Month End Close Checklist for Startups: From 15 Days to 5

Most funded Indian startups treat month-end close as an accounting task. Their finance team or CA runs through it in the background, and the founder gets a P&L somewhere between the 12th and 18th of the following month. By then, the board pack is already late, burn decisions are being made on stale numbers, and the investor update is half-guesswork. The close is not an accounting problem. It is an operating cadence problem, and one that Indian startups have it harder than their global counterparts because the accounting close and the compliance calendar both land in the same ten-day window every month. This article gives you a day-by-day close checklist designed for Indian startups, maps every India-specific compliance obligation into the sequence, and explains what to systematise first if you want to get from 15 days to 5.

How long should month-end close take for an Indian startup?

A well-structured Indian startup at seed or Series A should deliver investor-grade financials within 5 working days of month-end and complete compliance filings by the 20th. The close runs in two concurrent phases: an accounting close from Day 1 to Day 5 (covering bank reconciliation, accruals, TDS computation, revenue recognition, and management reporting), and a compliance close from the 14th to the 20th (covering GSTR-2B reconciliation and GSTR-3B filing). Both phases run simultaneously against the months own work, not sequentially.

Why Indian startup closes run so long

The median Indian startup close runs 12 to 18 working days. That means a founder trying to understand July’s financials gets the numbers in late August. By then, one more hiring decision has been made without data, one more vendor has been onboarded without a margin check, and the investor update has gone out with estimates.

The delay is almost never a headcount problem. It is almost always one of three structural failures:

Bookkeeping is done in batches, not daily. When transactions are being recorded weekly or fortnightly, the first week of the close is spent just getting the ledger current. Before any reconciliation can begin, the accountant is catching up on three weeks of bank entries, vendor bills, expense claims, and salary payments.

GST and TDS are treated as separate workflows. Most startup finance setups have accounting in one lane and compliance in another. The month-end accounting close wraps up, and then the GST team starts GSTR-2B reconciliation, and then the TDS team processes deductions. Each handoff adds three to five days. In a well-designed close, these workflows are concurrent, not sequential.

There is no owner accountability per task. When the close is a shared CA responsibility with no internal task owner, every blocker sits in an email thread. Bank statements do not get pulled. Vendor bills wait for approvals. Expense reimbursements sit in founders’ inboxes. The close drags because nobody is tracking individual task completion against a calendar.

What accounting standards apply to an Indian startup?

Before designing a close process, the founding team needs to know which accounting framework governs their financial statements. Indian Pvt Ltd companies below the Ind AS threshold (net worth below Rs. 250 crore and annual turnover below Rs. 500 crore) apply the older Indian Accounting Standards issued by the Institute of Chartered Accountants of India (ICAI). Once a company crosses either threshold, it becomes mandatory to transition to Indian Accounting Standards (Ind AS), which align with International Financial Reporting Standards (IFRS). For most seed-to-Series-A startups, the applicable framework is the older AS set. The close checklist in this article applies under both frameworks. Where Ind AS introduces a specific additional requirement (deferred revenue recognition under Ind AS 115 is one example, covered in Day 3 below), this is flagged explicitly. For a detailed breakdown of the transition thresholds and their implications for revenue recognition, the Treelife article on Ind AS applicability for private companies covers the mechanics.

What does “closed” actually mean for an Indian startup?

This definition matters because Indian startups frequently confuse “books updated” with “month closed.” A period is properly closed when all of the following are true:

• All bank accounts, credit cards, and payment gateway accounts are reconciled to zero variance
• All vendor bills (including accruals for services not yet invoiced) are recorded
• All revenue is recognised per the company’s revenue recognition policy
• TDS has been deducted at the time of credit or payment (whichever is earlier) on all applicable vendor payments, including accruals
• RCM has been computed and journalised on all import-of-services payments to foreign vendors
• GSTR-2B has been reconciled against the purchase register, and any mismatches are documented
• Payroll has been posted with PF, ESIC, and professional tax contributions recorded as liabilities
• Depreciation and amortisation entries have been posted
• All balance sheet accounts have a supporting schedule
• The P&L, Balance Sheet, and Cash Flow Statement are prepared and reviewed
• The accounting period is locked in the software so no retrospective entries can corrupt filed returns

Anything short of this is not a close. It is a draft. And investor-grade reporting requires a close, not a draft.

The India-specific compliance calendar: what runs alongside the accounting close

This is the piece that no global checklist covers, and the piece that makes Indian startup closes harder than their US or UK counterparts. Every month, the following compliance events are live in the same 10 to 20 day window as the accounting close.

Compliance calendar: first 25 days of every following month

Day	Event	Regulatory basis
7th	TDS deposit for previous month	Section 200, Income Tax Act 1961; Rule 30, Income Tax Rules
7th	TCS deposit for previous month	Section 206C, Income Tax Act 1961
10th	GSTR-7 (TDS deductors under GST)	Section 51, CGST Act 2017
11th	GSTR-1 (monthly filers, outward supplies)	Section 37, CGST Act 2017
13th	IFF (QRMP filers, months 1 and 2 of quarter only)	Section 37, CGST Act 2017
13th	GSTR-1 (QRMP filers, quarter-end month only)	Section 37, CGST Act 2017
14th	GSTR-2B available on portal	Section 38, CGST Act 2017
15th	PF and ESIC contributions due	EPF Act 1952; ESI Act 1948
20th	GSTR-3B (monthly filers)	Section 39, CGST Act 2017
25th	GST PMT-06 (QRMP filers)	Rule 85B, CGST Rules 2017
28th	Professional tax payment (Maharashtra, 20+ employees)	Maharashtra State Tax on Professions, Trades, Callings and Employments Act 1975

A note on QRMP and IFF: Quarterly Return Monthly Payment (QRMP) filers use the Invoice Furnishing Facility (IFF) in the first two months of each quarter to report outward B2B supplies. In the third month of the quarter, they file a full GSTR-1 (not IFF), with a 13th deadline for that quarter-end month. The compliance calendar above reflects the correct distinction. If your startup moved from monthly filing to QRMP, confirm which month of the quarter you are in before assuming IFF applies.

The critical insight: your accounting close must be designed around this calendar, not alongside it. GSTR-1 cannot be filed correctly if outward supply entries are not finalised by the 10th. GSTR-3B cannot be filed without completing GSTR-2B reconciliation, which is only available from the 14th. TDS deposit on the 7th requires that all accruals for the preceding month be posted before month-end so that TDS is computed on credit entries, not just on cash payments.

The two-phase close: how the 5-day accounting close and the compliance close fit together

This is the structural fix that collapses 15+ day closes. Most startups run their accounting close and their compliance close sequentially. The accounting team finishes its work, then hands off to the compliance team. Each handoff costs days.

The 5-day model runs them concurrently. Phase 1 (Days 1 to 5) is the accounting close. Phase 2 (14th to 20th of the same month) is the compliance close for the prior period. While your accounting team is closing June in Days 1 to 5 of July, your compliance calendar for June is running in parallel on the same July calendar. By the 5th, the accounting close for June is done and the management pack is out. By the 20th, GSTR-3B for June is filed on a fully reconciled basis. Nothing is sequential. Nothing waits.

The “from 15 days to 5” headline refers specifically to the accounting close and management reporting delivery. The compliance close (GSTR-2B reconciliation and GSTR-3B filing) runs concurrently and is complete by the 20th regardless of when the accounting close finishes, because GSTR-2B is only available from the 14th. Separating these two phases in your calendar is the single most important structural change you can make.

Day-by-day close checklist: the 5-day accounting close

This sequence assumes daily bookkeeping is current. If it is not, the first non-negotiable step is to build daily transaction recording into the finance calendar before attempting to compress the close.

Day 1 (1st of following month): transaction lock, bank reconciliation, and gateway reconciliation

The first working day is for locking all transactions in the prior month and beginning reconciliation. No new entries should be permitted in the prior period from this point.

Bank and card reconciliation:

• Export all bank statements for every account held by the company, including current accounts, savings accounts, and virtual accounts
• Match every bank line to a ledger entry. Flag all unmatched lines for resolution on Day 1 itself, not later
• Pull all credit card statements and match to expense entries
• Record all outstanding vendor bills received but not yet entered
• Confirm that all sales invoices raised in the month are entered and matched to revenue
• Check that payroll has been posted with gross-to-net breakdown and that PF, ESIC, and professional tax liability entries are in the books
• Post depreciation for fixed assets using the company’s depreciation schedule

Payment gateway reconciliation (separate procedure): Payment gateway accounts are not the same as bank accounts and must be reconciled separately. Three differences create systematic reconciliation gaps that confuse most startups:

First, settlement lag. Gateways typically settle on a T+1 or T+2 basis, meaning cash collected on the 30th of the month may not appear in the bank until the 1st or 2nd of the following month. This creates a timing difference between gateway revenue and bank credit that must be tracked through a gateway clearing account in the books.

Second, MDR (Merchant Discount Rate) deductions. The gateway deducts its fees before settling. If your books record the gross amount collected from the customer and the bank receives the net amount after MDR, the difference creates an unexplained reconciliation gap every month. Decide whether your policy is to record gross revenue and book MDR as a separate expense (recommended for revenue accuracy), or to record net revenue. Apply it consistently every month.

Third, refund reversals. Refunds processed through the gateway reverse a prior settlement and create a negative cash entry that sits in the gateway account until the next settlement cycle. If not tracked, refund reversals cause over-stated revenue in the month of original payment and phantom negative entries in subsequent months.

The fix is a dedicated gateway reconciliation schedule: gateway receipts for the month, less MDR, less refunds, equals expected settlement. Match expected settlement to actual bank credits. Any difference is either a timing item (carry forward to next month) or an error (investigate immediately).

This day is typically the longest. If bank and gateway reconciliation combined is taking more than one working day, the root cause is almost always a gap in daily bookkeeping.

Day 2 (2nd): accruals, TDS, RCM, and vendor liability sweep

Day 2 is the most compliance-dense day of the close. This is where most Indian startup closes accumulate errors.

Accruals: Post all month-end accruals for expenses where services have been delivered but no invoice has been received. Common startup accruals include:

• Professional fees (legal, audit, advisory, CA fees) where the engagement ran through the month but the invoice has not arrived
• Software subscriptions billed quarterly or annually, apportioned monthly
• Cloud infrastructure costs (billed by foreign entities) for the billing period just closed
• Marketing agency retainers
• Contractor fees where timesheet approval is pending

TDS at accrual (critical rule that most startup accountants get wrong): Under Section 194J, 194C, 194H, 194I, and related provisions of the Income Tax Act 1961, TDS is deductible at the time of credit to the vendor’s account or payment, whichever is earlier. The word “credit” means the accounting entry. When your finance team posts a month-end accrual for a vendor, TDS is due at that point, not when the invoice is received or the payment is made. This means your accrual entry must be split: debit the expense account, credit TDS payable for the applicable rate, and credit vendor payable for the net amount. If this is not done, your TDS challan on the 7th will be understated, and a mismatch will emerge when the vendor files their 26AS. Two rate updates from October 2024 remain in effect: commission and brokerage TDS dropped from 5% to 2% (Section 194H), and e-commerce operator TDS on seller payments dropped from 1% to 0.1% (Section 194-O). Section 194T (TDS on partner remuneration) applies from 1 April 2025. For a complete rate reference and applicability matrix, see the Treelife guide to TDS and TCS compliance.

RCM on import of services from foreign vendors: This is the GST obligation that runs in parallel with Section 195 TDS on the same foreign vendor payments, and it is missed by the large majority of early-stage Indian startups. Under Section 9(4) of the CGST Act 2017 and Section 5(4) of the IGST Act 2017, when an Indian entity receives services from a foreign supplier (a non-resident without a GSTIN), GST applies under Reverse Charge Mechanism (RCM). The Indian startup is the deemed supplier for GST purposes and must self-assess the applicable GST rate on the service value, pay it from the electronic cash ledger (not from ITC credit), and raise a self-invoice. The ITC on that RCM payment can be claimed in the same period, subject to standard ITC restrictions under Section 16 of the CGST Act 2017.

Practically, every SaaS infrastructure cost paid to a foreign vendor where the billing entity is overseas triggers RCM GST. This includes cloud compute platforms, collaboration tools, design tools, code hosting services, and any other software subscription billed by a non-resident entity. The journal entry at accrual or payment is: debit the expense account at gross, credit vendor payable at gross, then separately debit GST ITC receivable (RCM) at 18% of the taxable value, and credit RCM GST payable at the same amount. The net cash impact is zero if ITC is claimed in the same period, but the filing obligation is real: RCM liability must be reported in GSTR-3B under the “Tax payable under RCM” column, and the self-invoice must be raised and kept on record for audit. Failure to self-assess and pay RCM GST is treated as non-payment of tax under Section 73 and Section 74 of the CGST Act 2017, with interest at 18% per annum under Section 50.

Vendor liability sweep: Review the AP ageing report. Flag any vendor outstanding beyond 45 days that is classified as an MSME under the Micro, Small and Medium Enterprises Development (MSMED) Act 2006. Under Section 43B(h) of the Income Tax Act 1961 (inserted by Finance Act 2023), payment beyond 45 days to an MSME supplier disallows the expense in the year of accrual and allows it only in the year of actual payment. This is a cash-flow and tax-planning point that most early-stage startups miss until their first tax audit.

Day 3 (3rd): revenue recognition, deferred revenue, and GST outward supply check

Revenue recognition: Apply the company’s revenue recognition policy consistently. For SaaS or subscription businesses, revenue is recognised over the service period, not on the invoice date or the cash receipt date. If a customer paid Rs. 12 lakhs for a 12-month subscription in month one, Rs. 1 lakh is revenue in month one and Rs. 11 lakhs sits in deferred revenue (a current liability on the balance sheet). This distinction matters enormously in due diligence. Investors look at deferred revenue balances as a leading indicator of committed future revenue, and a deferred revenue schedule that does not reconcile to contracts is a red flag. For companies that have crossed the Ind AS threshold, revenue recognition follows the five-step model under Ind AS 115. For those still on the older AS framework, the principles are equivalent but the documentation requirements differ. The Treelife article on Ind AS 115 revenue recognition for SaaS businesses covers the mechanics of the deferred revenue waterfall in detail.

GST outward supply check: GSTR-1 for monthly filers is due by the 11th. To file correctly, all B2B invoices must be uploaded, classified by HSN/SAC code, and matched to the correct GSTIN of the recipient. For companies with Aggregate Annual Turnover (AATO) above Rs. 5 crore, e-invoicing via the Invoice Registration Portal (IRP) is mandatory for all B2B transactions as of FY 2026-27. Every invoice must have an Invoice Reference Number (IRN) assigned by the IRP before it is considered valid. For businesses with AATO above Rs. 10 crore, the 30-day reporting window applies: invoices must be uploaded to the IRP within 30 days of the invoice date. An invoice reported after this window receives no IRN, is invalid for GST purposes, and your customer cannot claim Input Tax Credit on it. This is a relationship and cash-collection risk, not just a compliance risk. Day 3 of the close is when you confirm that every outward supply invoice in the prior month has a valid IRN, so that GSTR-1 can be filed clean on the 11th.

Revenue reconciliation: The total revenue per the P&L must reconcile to the total of GSTR-1 outward supplies plus any exempt or non-GST revenue. If these numbers do not match, GSTR-2B will produce a mismatch for your customers, and your own GSTR-3B liability will be miscalculated.

Day 4 (4th): purchase register preparation and balance sheet review

GSTR-2B is auto-populated by the GSTN by the 14th of the following month, reflecting all invoices uploaded by your suppliers in the prior period. You cannot complete GSTR-2B reconciliation on Day 4 because GSTR-2B is not yet available. What you do on Day 4 is prepare your side of the reconciliation so that the moment GSTR-2B drops on the 14th, you can complete the match immediately and file GSTR-3B on the 20th. This preparation on Day 4 is what allows the compliance close to run on time even though GSTR-2B data arrives later.

Purchase register preparation: Export your purchase register (all inward supply invoices received in the month) with supplier GSTIN, invoice number, invoice date, taxable value, and GST amount for each line. Separately, list all RCM self-invoices raised during the month. This is your side of the GSTR-2B match. Suppliers who have not filed GSTR-1 will not appear in your GSTR-2B. If a key supplier is consistently absent, it is a signal to chase their compliance or reconsider the relationship, because Input Tax Credit on their invoices is at risk. ITC for FY 2025-26 can be claimed only until the September 2026 GSTR-3B filing. After that window, unclaimed ITC is permanently lost.

Balance sheet review: Every balance sheet account must have a supporting schedule. The P&L is what founders look at. The balance sheet is what investors look at in due diligence. Accounts to schedule and review on Day 4:

Balance sheet line	What the schedule must show
Cash and bank	Reconciliation statement for each account
Payment gateway clearing	Gateway receipts, MDR deductions, refunds, unsettled balance
Trade receivables	Invoice-level ageing, provision for doubtful debts
GST input tax credit	Monthly movement, match to GSTR-2B (pending), RCM ITC separately
Prepaid expenses	Policy, period, and monthly amortisation
Fixed assets	Cost, accumulated depreciation, WDV
Trade payables	Vendor-level ageing, MSME flag where applicable
TDS payable	Tax-wise, deductee-wise breakup
RCM GST payable	Foreign vendor-wise, period-wise
PF and ESIC payable	Head-wise computation, deposit status
Professional tax payable	State-wise, employee count
Deferred revenue	Contract-wise breakup, recognition schedule
Inter-company payable or receivable	Entity-wise, transaction-wise, arm’s-length rate
Shareholder equity	Paid-up capital, retained earnings, ESOP reserve

Day 5 (5th): review, lock, and reporting

By Day 5, the accounting entries are complete and the compliance preparation is done. This day is for review, final sign-off, and producing the management reporting package.

Variance review: Compare the current month’s P&L against the prior month and against budget. Any line item variance above 15% must have a written explanation, not just a number. Revenue down 20%: was it a delayed invoice, a lost customer, or a seasonal dip? Cloud costs up 25%: new product feature, a runaway job, or a pricing change from the vendor? These explanations become your board pack narrative. If you cannot explain every major variance within 24 hours of closing, your close does not have enough internal review built in.

Burn and runway update: Net burn for the month (cash out minus cash in) must be calculated and updated in the 13-week rolling cash flow model. With a 5-day close, the founder has burn and runway figures by the 5th working day of the following month rather than the 18th. The difference in decision quality is significant: a hiring decision, a vendor negotiation, or a fundraising timeline call made on the 5th with July data is materially better than the same call made on the 18th.

Lock the period: Lock the accounting period in your software immediately after review sign-off. This is non-negotiable. If team members can edit transactions in a closed period, your filed GSTR-1 and GSTR-3B will diverge from your books every time a back-dated entry is made. Reconciling this divergence at year-end is expensive and sometimes impossible.

Management reporting package: Produce and distribute the standard reporting pack:

• P&L (actual vs budget, actual vs prior month)
• Balance Sheet (current month vs prior month)
• Cash Flow Statement
• Burn and runway summary (gross burn, net burn, cash on hand, months of runway)
• KPI dashboard (revenue, collections, headcount cost, unit economics where applicable)

This pack goes to the founding team first. The investor-facing version follows the same structure but is filtered for the metrics each investor cares about per the SHA reporting covenants, if any. For a full breakdown of what goes into a startup MIS pack and how to structure it by business model, the Treelife MIS reporting for startups guide covers each component.

The compliance close: 14th to 20th (runs concurrently, not after)

This phase runs in the same month as the accounting close, not after it. While the Day 1 to Day 5 accounting close for June is happening in the first week of July, the compliance close for May is completing in parallel in the same July calendar.

14th: GSTR-2B becomes available. Run the purchase register prepared on Day 4 against GSTR-2B. Identify and document all mismatches. Mismatches fall into three categories: invoices in your register not in GSTR-2B (vendor has not filed, chase them or defer the ITC claim), invoices in GSTR-2B not in your register (entry missed, post it), and value or tax mismatches (investigate and correct in books or raise a dispute with the vendor).

15th to 19th: Complete GSTR-3B preparation. Consolidate outward tax liability (from GSTR-1), inward ITC eligible (from reconciled GSTR-2B), RCM liability (from self-invoices), and net tax payable. Verify that the electronic cash ledger has sufficient balance for any cash payment required.

20th: File GSTR-3B. Do not file before GSTR-2B reconciliation is complete. Filing on the basis of the internal purchase register without reconciling against GSTR-2B is the single most common GST compliance error Indian startups make.

How to build daily bookkeeping (the prerequisite for a 5-day close)

The 5-day accounting close is not achievable without daily bookkeeping. If transactions are being recorded weekly or at month-end, the close will always start from a deficit. Daily bookkeeping does not require a full-time accountant. It requires a process:

• Bank feeds connected to the accounting software (cloud-based platforms with auto-import enabled work best)
• All vendor bills entered within 24 hours of receipt, with GL coding completed at entry, not at month-end
• Expense claims submitted weekly with receipt images, not monthly in a bundle
• Sales invoices raised on the day of delivery or service completion, not at month-end
• Payment gateway reconciliation reports pulled daily or weekly, not month-end

For a seed-stage startup doing 200 to 500 transactions per month, this is 30 to 45 minutes of daily finance work. The payoff is a close that starts with a current ledger on Day 1 rather than a 3-week backlog.

What changes when you raise a Series A

The close does not get harder at Series A. It gets more formal. The differences are:

Board reporting frequency: Most Series A SHA agreements include a clause requiring monthly management accounts to be shared with investors within 10 to 15 business days of month-end. A 5-day close makes this trivially achievable. A 15-day close makes it structurally impossible, and an investor who consistently receives late or unreconciled reports will begin to lose confidence in the founding team’s operational grip. For a full treatment of what investor-grade financial reporting looks like at Series A, see the Treelife guide to how a virtual CFO gets your startup Series A ready.

Audit trail requirements: By the time a company approaches a Series B or an international investor, the data room will request 12 to 24 months of monthly management accounts. These need to be consistent, comparable, and produced on the same reporting basis every month. A close process that varies month to month produces accounts that are difficult to compare and expensive to explain.

ESOP accounting: Once ESOPs are granted, the fair value of options must be expensed over the vesting period using the Black-Scholes or binomial model (Guidance Note on Accounting for Employee Share-Based Payments, ICAI). This creates a monthly non-cash charge to the P&L and a corresponding credit to the ESOP reserve in equity. Most early-stage startups forget to post this entry monthly, then face a large prior-period adjustment when their auditors pick it up. Post the ESOP charge every month as part of the close.

Transfer pricing and inter-company (multi-entity structure): This is the caveat that extends the 5-day close for a significant number of funded Indian startups. If the startup has incorporated an offshore holding entity (Singapore, Mauritius, Delaware, or Cayman are common), the Indian operating entity is likely receiving or paying for services under an inter-company arrangement: a management fee, a software licence, a cost-plus service agreement, or a loan with interest. The close of the Indian entity depends on receiving a charge statement from the parent entity. Until that statement arrives and is reviewed at arm’s length, the inter-company payable or receivable cannot be finalised. This creates a dependency that sits outside the Indian finance team’s control.

The fix is to establish a shared close calendar with the parent entity’s finance team (or its accounting service provider), set a hard deadline for the charge statement (typically the 2nd of the following month), and build the inter-company posting as a standing accrual at the agreed monthly rate even if the formal statement arrives late. Adjustments are made in the following month when actuals are confirmed. Any management fee, software licence, or cost-sharing arrangement between the Indian entity and the foreign entity must be journalised monthly and is a transfer pricing assessment item under Section 92 of the Income Tax Act 1961. The 5-day close timeline assumes a single-entity structure. Multi-entity setups realistically need an additional 2 to 3 days, giving a 7 to 8 day accounting close as the practical target.

Common mistakes that extend the close and cost Indian startups

Not deducting TDS on cloud and software subscriptions paid to foreign vendors, and missing the RCM obligation on the same payments. Foreign cloud infrastructure and SaaS platforms bill Indian entities for services. Two separate obligations apply simultaneously. Under Section 195 of the Income Tax Act 1961, payments to non-residents for services that have a source in India attract TDS at rates ranging from 10% to 15% (or DTAA rates where a treaty applies). Separately, GST under RCM applies on the same payment under Section 9(4) of the CGST Act 2017. Most startups miss both. The TDS liability accumulates silently and emerges as a demand in assessment. The RCM liability is non-payment of GST, attracting 18% interest under Section 50 of the CGST Act. Check every foreign vendor payment against both the Section 195 TDS matrix and the RCM applicability list.

Not deducting TDS at accrual, and incurring interest under Section 201(1A). Beyond the Section 234E late filing fee of Rs. 200 per day per return, startups that fail to deduct TDS on accruals face interest under Section 201(1A) of the Income Tax Act 1961. The rate is 1% per month from the date TDS was deductible to the date of deduction, and 1.5% per month from the date of deduction to the date of deposit. For a startup that has missed TDS on 12 months of professional fee accruals at Rs. 5 lakhs per month with a 10% TDS rate, the interest charge alone runs to Rs. 90,000 at 1.5% per month over the period. This compounds every month the error is uncorrected.

Claiming ITC on invoices not in GSTR-2B. Section 16(2)(aa) of the CGST Act 2017 (inserted by Finance Act 2021, operative from 2022) restricts ITC to amounts appearing in the taxpayer’s GSTR-2B. If a vendor has raised an invoice, you have paid it, and it does not appear in your GSTR-2B because the vendor has not filed their GSTR-1, you cannot claim ITC on that invoice in the current month. Claiming it anyway triggers a DRC-01C mismatch notice from the GSTN. The correct treatment is to carry the claim to a future month when the vendor complies, or to chase the vendor to file their return.

Filing GSTR-3B before completing GSTR-2B reconciliation. Some startups file GSTR-3B on the basis of their internal purchase register rather than waiting for GSTR-2B. If any supplier has cancelled or amended an invoice in GSTR-1, your internal register will overstate ITC and your GSTR-3B will be wrong. File GSTR-3B only after GSTR-2B has been reconciled.

Booking prepaid expenses entirely in the month of payment. Annual software subscriptions, insurance premiums, and security deposits paid in a lump sum are not fully expensable in the month of payment. They must be capitalised as a prepaid asset and amortised monthly over the benefit period. A startup that books a Rs. 12 lakh annual SaaS subscription entirely in one month shows a cost spike that confuses its own P&L and makes month-on-month comparison meaningless.

Missing professional tax in the payroll close. Professional tax is a state-level obligation that most early-stage startups omit from their close checklist. In Maharashtra (where a large share of funded startups are domiciled), the rate is Rs. 200 per month per employee for salaries above Rs. 10,000, capped at Rs. 2,500 per year per employee. Payment is due by the last day of the following month for monthly filers, and returns are filed twice a year. Karnataka, Telangana, and West Bengal have similar obligations at different rates. Any payroll close that does not include a professional tax computation and a liability entry is incomplete.

No lock on closed periods. If your accounting software allows back-dated entries in a closed and filed month, you will eventually face a situation where books and filed returns diverge. The fix costs more than the original error.

FAQs

Q: What is month-end close?
A: Month-end close is the process of finalising all financial transactions for a month and producing accurate financial statements including the P&L, Balance Sheet, and Cash Flow Statement. For an Indian Pvt Ltd startup, a close is not complete until bank and gateway reconciliations are done, GST and TDS obligations (including RCM) are computed, accruals are posted, and the accounting period is locked in the software.

Q: How many days should month-end close take for an Indian startup?
A: A seed-to-Series-A Indian startup with good daily bookkeeping hygiene should deliver management accounts within 5 to 7 working days of month-end, with GSTR-3B filed by the 20th as part of the concurrent compliance close. Multi-entity structures with inter-company dependencies realistically need 7 to 8 working days for the accounting close.

Q: What is the difference between the accounting close and the compliance close?
A: The accounting close (Days 1 to 5) covers bank and gateway reconciliation, accruals, TDS computation, revenue recognition, balance sheet schedules, and management reporting. The compliance close (14th to 20th) covers GSTR-2B reconciliation and GSTR-3B filing. They run concurrently in the same calendar month, not sequentially. Running them sequentially is the primary reason close cycles extend beyond 15 days.

Q: What is GSTR-2B and why does it affect the close timeline?
A: GSTR-2B is the auto-drafted Input Tax Credit statement generated by the GSTN by the 14th of each month. It reflects invoices uploaded by your suppliers in GSTR-1 for the prior month. Under Section 16(2)(aa) of the CGST Act 2017, ITC is restricted to amounts appearing in GSTR-2B. A startup cannot finalise its GST liability for the month until GSTR-2B is available and reconciled against its internal purchase register.

Q: What is QRMP and does it change the compliance calendar?
A: QRMP (Quarterly Return Monthly Payment) is an optional scheme for GST taxpayers with annual aggregate turnover below Rs. 5 crore. QRMP filers file GSTR-1 quarterly (using the Invoice Furnishing Facility for the first two months of each quarter and a full GSTR-1 at quarter end, both by the 13th of the month following the relevant period). They pay GST monthly via PMT-06 by the 25th. If your startup is on QRMP, confirm which month of the quarter you are in before planning the compliance close: IFF applies in months 1 and 2, full GSTR-1 applies in month 3.

Q: When is TDS deducted: at payment or at accrual?
A: At whichever happens first, as per Section 194J, 194C, 194H, and other applicable sections of the Income Tax Act 1961. “Credit” means the accounting entry. If your finance team posts a month-end accrual for a professional fee, TDS is due at that point. Startups that deduct TDS only at cash payment are routinely understating their TDS liability and generating 26AS mismatches for vendors. Interest under Section 201(1A) accrues at 1.5% per month from the date of deduction to the date of deposit.

Q: What is RCM GST and when does it apply to a startup?
A: Reverse Charge Mechanism (RCM) GST applies when an Indian entity receives services from a foreign supplier without a GSTIN, under Section 9(4) of the CGST Act 2017 and Section 5(4) of the IGST Act 2017. The Indian startup must self-assess GST at the applicable rate (typically 18% for B2B services), pay it from the electronic cash ledger, raise a self-invoice, and claim the ITC in the same period. Every payment to a foreign cloud infrastructure or SaaS vendor where the billing entity is a non-resident triggers this obligation. It runs in parallel with Section 195 TDS on the same payments.

Q: Does e-invoicing apply to my startup?
A: E-invoicing under GST is mandatory for all B2B transactions if your Aggregate Annual Turnover (AATO) exceeds Rs. 5 crore. From 1 April 2026, businesses crossing this threshold in FY 2025-26 must generate all B2B invoices via the Invoice Registration Portal (IRP). Businesses with AATO above Rs. 10 crore must upload invoices to IRP within 30 days of the invoice date; invoices uploaded after this window receive no IRN and are invalid for ITC purposes.

Q: What is the cost of a late or missing month-end close for a startup?
A: Late TDS returns attract a fee of Rs. 200 per day per return under Section 234E. Failure to deduct TDS attracts interest at 1% per month under Section 201(1A); failure to deposit after deduction attracts 1.5% per month. Late GSTR-3B attracts Rs. 50 per day (Rs. 20 for nil returns), capped at Rs. 5,000. RCM not self-assessed attracts 18% interest under Section 50 of the CGST Act. Incorrectly claimed ITC triggers reversal plus 18% interest. MSME vendor payments beyond 45 days lose their deductibility under Section 43B(h).

Q: Do we need a VCFO or a bookkeeper to run a 5-day close?
A: A 5-day close is achievable with a good bookkeeper plus a CA who understands the Indian compliance calendar. A VCFO adds value on top: they own the variance review, build the management reporting pack, manage investor-facing reporting, and spot the structural issues (TDS-at-accrual failures, RCM gaps, MSME vendor risks, gateway reconciliation errors) that a bookkeeper will not flag. For a startup raising a Series A or managing more than Rs. 2 crore per month in transactions, fractional VCFO involvement in the close pays for itself.

Q: What accounting software works best for Indian startup month-end close?
A: Cloud-based accounting platforms with GSTN integration offer bank feed automation and built-in TDS management. Desktop-based accounting software remains widely used and is auditor-compatible but typically requires more manual setup for bank feeds. For SaaS startups with deferred revenue, a dedicated deferred revenue module or a well-maintained spreadsheet schedule alongside the accounting software is necessary. The choice matters less than the configuration: any software left unconfigured for GST, TDS, and RCM handling will not support a 5-day close.

Q: Should payroll be part of the month-end close?
A: Yes. Payroll must be processed and posted before the close can be called complete. This includes gross salaries, PF employer contribution (12% of basic, per the Employees’ Provident Fund and Miscellaneous Provisions Act 1952), ESIC employer contribution (3.25% of gross wages, per the Employees’ State Insurance Act 1948), professional tax (state-level, rate varies by state, e.g. Rs. 200 per month per employee in Maharashtra for salaries above Rs. 10,000), and TDS withheld from salary under Section 192 of the Income Tax Act 1961. PF and ESIC must be deposited by the 15th; professional tax by the 28th (Maharashtra).

Q: What is the MSME 45-day rule and how does it affect month-end close?
A: Under Section 43B(h) of the Income Tax Act 1961 (inserted by Finance Act 2023), payments to MSME suppliers registered under the MSMED Act 2006 must be made within 45 days of the invoice date (or within the agreed credit period, whichever is earlier, subject to a maximum of 45 days). If payment is not made within this window, the accrued expense is disallowed in the current year and is allowed only in the year of actual payment. During the close, the AP ageing report must flag every MSME creditor outstanding beyond 30 days for immediate escalation.

Q: How does the month-end close connect to audit readiness?
A: Directly. A startup with 12 months of clean, locked, reconciled closes with supporting schedules for every balance sheet account can complete a statutory audit in 3 to 4 weeks. A startup with inconsistent closes, back-dated entries, and un-reconciled balance sheet accounts typically takes 3 to 4 months, with significant additional CA fees and management time. Close quality is audit readiness.

Q: What is the impact on fundraising if my close is poor?
A: Financial due diligence for a Series A or Series B almost always includes an FDD exercise by the investor’s CA or a Big 4 firm. They will request 12 to 24 months of monthly management accounts. If those accounts are inconsistent, unreconciled, or delayed, the FDD report will flag material weaknesses in financial controls. This directly impacts valuation negotiation and can delay or derail a round.
