Decoding DPIIT Deep Tech for startups: eligibility and taxation

The Department for Promotion of Industry and Internal Trade formally defined Deep Tech Startup as a distinct legal category for the first time on 4 February 2026, through Gazette Notification G.S.R. 108(E). For founders working on semiconductors, quantum systems, novel biotech, or advanced materials, two separate questions follow from that notification, and founders routinely conflate them. The first is whether the company meets the eligibility criteria for Deep Tech status at all. The second, entirely separate, is what tax treatment actually follows once it does. This article answers both, in order, with the gazette text as the source rather than a summary of a summary.

Where do the DPIIT Deep Tech startup eligibility criteria come from?

The notification, formally titled G.S.R. 108(E), supersedes the earlier Gazette Notification G.S.R. 127(E) dated 19 February 2019 and takes effect from its date of publication in the official gazette, 4 February 2026 (Notification G.S.R. 108(E), Ministry of Commerce and Industry, Department for Promotion of Industry and Internal Trade, 4 February 2026). It does three things at once. It raises the general startup turnover ceiling from ₹100 crore to ₹200 crore. It expands eligible entity types to include Multi-State Cooperative Societies and State Cooperative Societies, alongside the existing private limited company, partnership firm, and LLP structures. And, separately from both of those, it inserts a formal definition of Deep Tech Startup, a category that did not exist as a distinct legal term under the 2019 notification.

Treelife has already covered the general reforms, the turnover increase and the cooperative society expansion, in detail in our breakdown of the revised startup recognition framework. This article does not repeat that ground. It stays inside the Deep Tech provision, because that is where the practical ambiguity for founders actually sits.

What are the four DPIIT Deep Tech startup eligibility criteria?

A Deep Tech Startup is a Startup that additionally meets four specific eligibility criteria set out in the explanation clause of the notification, clause (n). All four must be present, not just one or two.

The notification defines Deep Tech Startup as an entity that, first, is working on a solution based on new knowledge or advancement within a scientific or engineering discipline, or across multiple disciplines, which is still being developed or is yet to be developed. Second, it must show a high percentage of research and development expenditure relative to its total revenue or funding. Third, it must own, or be actively in the process of creating, significant novel intellectual property, while taking concrete steps toward commercialising that IP. Fourth, it must be facing extended development timelines, long gestation periods, high capital and infrastructure requirements, and material technical or scientific uncertainty (Notification G.S.R. 108(E), Explanation clause (n), 4 February 2026).

Read together, this is a test built to exclude companies that use the word deep tech loosely. A company applying machine learning to a known problem with a working product and paying customers is unlikely to satisfy the third and fourth prongs, novel IP under active development and material technical uncertainty, even if its underlying technology is genuinely sophisticated. A company still validating a novel battery chemistry, a new antibody platform, or a photonic chip architecture with no proven yield, is squarely inside the intended scope.

Deep Tech attributes at a glance

Attribute	What DPIIT is testing for	Common founder misread
Novel scientific or engineering solution	The core technology is new, not an application of existing technology	Believing “AI-powered” alone satisfies this
High R&D spend relative to revenue or funding	A funding and expense pattern that looks like research, not sales	Underestimating how R&D-heavy the ratio needs to look
Ownership or active creation of novel IP, with commercialisation steps	Filed or filing patents, plus a credible path to market	Treating a provisional patent filing as sufficient on its own
Extended timelines, high capital needs, technical uncertainty	The business genuinely cannot commercialise on a typical startup timeline	Framing long timelines as a weakness rather than the qualifying feature

Why hasn’t DPIIT published the actual assessment framework yet?

The direct answer is that the notification deliberately leaves the detailed evaluation criteria to a future DPIIT framework, and that framework had not been separately published as of the date of writing. The gazette text itself says the determination of whether an entity satisfies the Deep Tech attributes will be made in accordance with such framework, parameters, and guidelines as may be issued by the Department from time to time, based on documents and information the applicant furnishes in the manner specified on the online application portal (Notification G.S.R. 108(E), Explanation clause (n), proviso, 4 February 2026).

This is a meaningful gap that most surface-level coverage of the notification skips past. The four attributes in the gazette are the legal test. The operational rubric, how DPIIT actually scores R&D-to-revenue ratios, what counts as sufficient documentation of technical uncertainty, and how reviewers will treat borderline sectors like applied AI or climate tech, sits with a portal-level framework that is issued separately and can change without a fresh gazette notification. Founders who wait for that granular guidance before assembling their documentation will be better positioned than those who apply on the four-attribute text alone and get rejected on interpretation grounds that have not yet been made public.

In practical terms, this means the safest approach right now is to build a Deep Tech application file around the strongest possible evidentiary version of each of the four attributes, patent filing records, R&D expense schedules as a percentage of total spend, a technical uncertainty memo written by the company’s own scientific or engineering lead, rather than assuming any single document will satisfy DPIIT on its own.

For a Deep Tech Startup, the recognition period extends to twenty years from the date of incorporation or registration, compared to ten years for a regular Startup, and the turnover ceiling before an entity loses status rises to ₹300 crore for any financial year since incorporation, compared to ₹200 crore for a regular Startup (Notification G.S.R. 108(E), proviso to clause 1(a), 4 February 2026).

Regular startup versus deep tech startup, recognition parameters

Parameter	Regular startup	Deep tech startup	Where it is set out
Recognition period	10 years from incorporation	20 years from incorporation	Notification clause 1(a)(ii), proviso
Turnover ceiling	₹200 crore in any financial year	₹300 crore in any financial year	Notification clause 1(a)(iii), proviso
Eligible entity types	Pvt Ltd, LLP, partnership firm, cooperative societies	Same entity types, with Deep Tech attribute test layered on top	Notification clause 1(a)(i)
80-IAC certifying body	Inter-Ministerial Board of Certification	Same Board, now including DBT and DST representatives	Notification clause 1(c)

The scale of the change is significant for founders in sectors like semiconductors and clinical-stage biotech, where a decade is often not enough to get from incorporation to a commercially validated product. Under the 2019 framework, a semiconductor design company that took nine years to tape out a commercially viable chip had effectively one year of startup status left to raise capital and build revenue before losing every DPIIT-linked benefit. The 20-year window removes that cliff for companies that can demonstrate genuine Deep Tech status, though it does not extend the clock for companies that fail the attribute test and remain classified as regular Startups.

One nuance worth flagging for finance teams. The turnover figure that matters is defined by reference to Section 2, clause 91 of the Companies Act 2013 (Notification G.S.R. 108(E), clause 1(k)), not by any tax return figure or a founder’s informal sense of revenue. Founders tracking their own eligibility internally should use the Companies Act definition of turnover, not GST turnover or accounting revenue under a different standard, when checking where they sit against the ₹300 crore line.

How is a DPIIT Deep Tech startup actually taxed?

Eligibility and taxation are two separate questions, and this is where most founder confusion sits. DPIIT recognition, including Deep Tech recognition, is an administrative status. It does not, by itself, change a single number on a tax return. The tax benefits available to a Deep Tech Startup come from four distinct provisions, each with its own application, its own conditions, and in most cases its own filing.

Section 80-IAC: the three-year profit holiday

A Startup, including a Deep Tech Startup, that is a private limited company or an LLP and meets the conditions in the Explanation to Section 80-IAC of the Income Tax Act 1961 may apply separately, in Form 1, to the Inter-Ministerial Board of Certification for a certificate that unlocks a 100 percent profit exemption for any three consecutive years within the recognition period (Notification G.S.R. 108(E), clause 3, 4 February 2026). For a regular Startup, those three years must fall within the first ten years from incorporation. For a Deep Tech Startup, the same three-year exemption applies, but the founder has the full twenty-year recognition window to choose from, which matters given how long deep tech companies typically take to reach profitability.

What changed under the 2026 notification is who reviews the application. The Inter-Ministerial Board now formally includes a representative of the Department of Biotechnology and a representative of the Department of Science and Technology, alongside the Joint Secretary of DPIIT who convenes it (Notification G.S.R. 108(E), clause 1(c), 4 February 2026). Founders applying for 80-IAC certification as a Deep Tech company should expect more technically substantive review questions than a generalist software startup would face, since two of the Board’s members now have a scientific and technical background specifically added for this purpose.

Founders should also note that from 1 April 2026, the Income Tax Act 1961 provisions referenced in the notification are superseded by the Income Tax Act 2025, notified on 21 August 2025. Section 80-IAC itself is renumbered as Section 140 under the new Act, so a Deep Tech company applying for certification on or after that date should cite Section 140 for filings covering the new tax year, while filings covering periods before 1 April 2026 continue to reference Section 80-IAC of the 1961 Act (Notification G.S.R. 108(E), footnote to clause 3, 4 February 2026).

Section 35: why the R&D deduction matters more for a Deep Tech company

Section 35 deductions for scientific research expenditure are a general provision, available to any company regardless of DPIIT status, and Treelife’s guide to startup tax exemptions covers the mechanics, including the specific sub-clauses and rates, in full. What is worth flagging here is the overlap that is specific to Deep Tech. A high ratio of R&D expenditure to revenue or funding is itself one of the four Deep Tech eligibility attributes, which means the same expense schedule a founder builds to document R&D intensity for the eligibility application is also the schedule a tax advisor needs to size the Section 35 deduction. Building that schedule once, with both uses in mind, avoids reconstructing it twice.

MAT: why it changes the deep tech holiday math more than most founders expect

MAT continues to apply to companies during the 80-IAC exemption period, and the current rate and carry-forward rules are covered in Treelife’s guide to startup tax structuring. The point specific to Deep Tech is timing. Because a Deep Tech company can choose its three exemption years from anywhere within a twenty-year window rather than ten, the MAT position in the surrounding years, including whether MAT credit is still accumulating under the rules applicable at the time, becomes a genuine variable in deciding which three years to claim, not a fixed backdrop the way it is for a regular Startup with a shorter window to choose from.

ESOP deferral: a longer gap before it matters, then it matters more

The ESOP perquisite tax deferral available to eligible startup employees operates independently of Deep Tech status. What is worth flagging here is a recent change. The deferral, previously under Section 192(1C) of the Income Tax Act 1961, now sits under Section 392(3) read with Section 289(3) of the Income Tax Act 2025, and for shares allotted on or after 1 April 2026, the deferral window extends from 48 months to 60 months from the end of the relevant tax year of allotment. For a Deep Tech company specifically, the practical risk window is longer still. Given the sector’s typical development timelines, a Deep Tech company may grant ESOPs years before any realistic liquidity event, which means the DPIIT and IMB certificates need to stay current for far longer before an employee actually benefits from the deferral, making certificate renewal tracking a longer-running compliance item than it is for a faster-moving consumer startup.

Deep tech taxation at a glance

Provision	What it does	Who administers it	Automatic on DPIIT recognition?
Section 80-IAC (Section 140 from 1 April 2026)	100% profit exemption for 3 consecutive years within the recognition window	Inter-Ministerial Board of Certification, separate Form 1 application	No, requires a separate application
Section 35	Deduction for R&D revenue expenditure and weighted in-house R&D deduction	Standard income tax assessment	No, available to any company meeting the section’s conditions, DPIIT status not required
MAT	Minimum tax on book profit, applies even during the 80-IAC holiday	Standard income tax assessment	Not applicable, applies regardless
ESOP deferral (Section 192(1C), now Section 392(3) read with Section 289(3))	Defers perquisite tax on ESOP exercise for eligible startup employees, window extended to 60 months for shares allotted from 1 April 2026	Employer, based on valid DPIIT and IMB status	Requires valid DPIIT recognition, and IMB certification where relevant, at time of allotment

What fund deployment restrictions apply to deep tech startups specifically?

This is the section most Deep Tech founders underestimate, because the restrictions read like generic anti-abuse language but bind harder on capital-intensive R&D businesses than on a typical software company.

The notification requires a Startup, including a Deep Tech Startup, to deploy its funds primarily toward core business activities, innovation, research, scaling, or operational requirements, and, outside the ordinary course of business, prohibits investment in a defined list of asset classes during the recognition period (Notification G.S.R. 108(E), clauses 4 and 5, 4 February 2026).

• Residential property, unless used for the startup’s own business purposes or held as stock-in-trade
• Non-residential land or buildings, unless occupied for business use or held as stock-in-trade in the ordinary course of business
• Loans and advances, unless lending is a substantial part of the business or the advances arise in the ordinary course of business
• Capital contributions to other entities, unless directly related to the startup’s business or strategic objectives
• Investment in shares and securities, unless incidental to treasury operations or part of the core business
• Motor vehicles, aircraft, yachts, or other high-value transport, unless used operationally, for leasing, hiring, or as stock-in-trade
• Jewellery or other luxury assets, unless held as stock-in-trade in the ordinary course of business
• Any other speculative or non-productive asset or activity as the Central Government may separately notify

For a SaaS or fintech startup, most of this list is easy to comply with by default. For a deep tech company, it is not. Buying a lab building rather than leasing one, holding a fabrication facility as a fixed asset, parking a large equity round in short-term securities while the R&D roadmap is finalised, or a founder-held company vehicle used to transport prototype hardware between labs, are all real scenarios that fall inside these restricted categories unless the company can show the acquisition is integral to its core business operations. The carve-out language, integral to its core business operations, is doing significant work here and is exactly the kind of clause that benefits from a documented internal memo at the time of purchase, not a retrospective justification during a certification review or an investor’s due diligence.

Common mistakes that cost founders time and money on Deep Tech eligibility

Treating the 80-IAC holiday as the only tax lever available. Founders who focus exclusively on the three-year 80-IAC exemption often miss that Section 35 R&D deductions apply regardless of DPIIT status and that MAT continues to apply during the holiday itself. A Deep Tech company that models 80-IAC in isolation, without MAT and without stacking Section 35 deductions, typically overstates the actual cash tax saved in a profitable year.

Applying for Deep Tech recognition before the R&D-to-revenue ratio is documented. DPIIT wants to see a high percentage of R&D expenditure against revenue or funding as one of the four attributes. Founders who apply with a generic set of financial statements, rather than a schedule that isolates R&D spend as a distinct line, make the reviewer do work that should have been done in advance, and inconsistent categorisation is a common reason for a request for additional information.

Treating DPIIT recognition and 80-IAC certification as one application. These are separate filings to separate review bodies, and a founder who assumes the DPIIT certificate automatically confers the tax holiday will miss the Form 1 application to the Inter-Ministerial Board entirely, sometimes for years, forfeiting profitable years that could have counted toward the three-year exemption window.

Buying or holding capital assets without a documented core-business justification. Given the restrictions in clauses 4 and 5, a deep tech company that purchases lab premises, holds a company vehicle, or parks surplus funding in securities without a contemporaneous internal note tying the asset to core operations, creates an unforced compliance gap that surfaces during 80-IAC review or, later, during investor due diligence.

Assuming the four-attribute test is self-certifying. The gazette text is explicit that DPIIT determines Deep Tech status based on documents and information the applicant furnishes in the manner the Department specifies, not on the founder’s own characterisation of the business. A pitch deck that calls the company deep tech is not evidence; a patent filing schedule, an R&D expense breakdown, and a technical uncertainty memo are.

Filing for Deep Tech status when the company would qualify more easily, and just as usefully, as a regular Startup. Not every scientifically sophisticated company needs the 20-year window or the ₹300 crore ceiling in its first several years. A company still well inside the ₹200 crore turnover limit and the 10-year window gains little from the additional Deep Tech documentation burden and review scrutiny, and can revisit the Deep Tech application closer to the point where the standard thresholds would actually bind.

Treelife practitioner note

In the DPIIT recognition and 80-IAC engagements we have run at Treelife, the single biggest predictor of a smooth Deep Tech application is whether the R&D expense schedule existed before the application was drafted, or was assembled afterward to fit the notification’s language. A founder who can hand us a clean, auditor-reviewed breakdown of R&D spend against total expenditure, mapped to the financial years the company is claiming recognition for, moves through the Inter-Ministerial Board review meaningfully faster than one who reconstructs that split from general ledger entries during the filing process itself. We have also started advising clients to prepare the technical uncertainty memo, required under attribute four, as a document authored by the company’s own scientific or technical lead rather than by legal or finance, since Board members from the Department of Biotechnology and the Department of Science and Technology are now formally part of the review under clause 1(c), and a memo written in founder-legal language rather than domain-specific technical language tends to generate more clarification requests, not fewer. One pattern only visible from running live transactions: companies that apply for Deep Tech recognition and 80-IAC certification in the same filing cycle, rather than sequentially, generally reach a certified outcome faster than those that wait for the DPIIT certificate before starting the Form 1 process, because the underlying documentation largely overlaps.

Case study

Situation: A pre-Series A quantum sensing hardware company based in Bengaluru, incorporated in 2019, approaching its original 10-year DPIIT recognition limit under the 2019 framework.

Challenge: The founders had never separated R&D expenditure from general operating costs in their books, had two provisional patents but no evidence of active commercialisation steps, and held a leased lab facility that had recently been converted to a purchased asset without any internal documentation tying it to core operations.

What Treelife did: We rebuilt three years of R&D expense schedules from the general ledger, drafted a technical uncertainty memo with the company’s chief scientist, filed the commercialisation roadmap alongside the existing patent filings, and prepared a core-business justification memo for the lab facility purchase ahead of the Deep Tech and 80-IAC applications being filed in the same cycle.

Outcome: The company received Deep Tech Startup recognition with the extended 20-year window, and its 80-IAC certification was approved without an additional information request, preserving two further years of the three-year tax holiday window that would otherwise have been at risk under the original 10-year limit.

FAQ’s on Decoding DPIIT Deep Tech for startups

Q: What are the DPIIT Deep Tech startup eligibility criteria in one line?
A: A company must first meet the standard Startup criteria, incorporation form, age, and turnover, and then satisfy four additional attributes: a novel scientific or engineering solution still under development, a high ratio of R&D spend to revenue or funding, ownership or active creation of significant novel IP with a commercialisation plan, and extended timelines with material technical or scientific uncertainty (Notification G.S.R. 108(E), Explanation clause (n)).

Q: Does DPIIT Deep Tech recognition automatically give me the section 80-IAC tax holiday?
A: No. Deep Tech recognition and 80-IAC certification are separate applications. A private limited company or LLP must separately apply in Form 1 to the Inter-Ministerial Board of Certification and satisfy the conditions in the Explanation to Section 80-IAC before the three-year tax exemption applies (Notification G.S.R. 108(E), clause 3).

Q: How does the ₹300 crore Deep Tech turnover ceiling interact with the income tax provisions?
A: They do not move together, and this is a distinction founders frequently miss. The ₹300 crore figure governs DPIIT Deep Tech status. The turnover ceiling written into Section 80-IAC of the Income Tax Act itself remains ₹100 crore in the previous year relevant to the assessment year for which the deduction is claimed, and has not been raised to match the DPIIT figure. A Deep Tech Startup can hold valid DPIIT recognition well past ₹100 crore in turnover and still lose 80-IAC eligibility for that year at the lower statutory threshold. Founders should track the ₹100 crore line for 80-IAC purposes specifically, separately from the ₹300 crore DPIIT recognition ceiling, and confirm the current figure with a tax advisor before assuming the two move together.

Q: What does it cost to apply for DPIIT Deep Tech recognition?
A: DPIIT does not charge a fee for Startup or Deep Tech recognition applications filed through the National Single Window System portal. The cost founders should budget for is advisory time to prepare the R&D expense schedule, technical uncertainty memo, and commercialisation documentation the four-attribute test requires, since incomplete documentation is what drives delay, not any government filing fee.

Q: How long does Deep Tech recognition and 80-IAC certification take end to end?
A: DPIIT recognition itself is typically processed within a few weeks once documentation is complete. The separate 80-IAC certification through the Inter-Ministerial Board typically takes 45 to 90 days from a complete Form 1 filing, longer if the Board requests additional documents or information under clause 3.

Q: What documents does a Deep Tech applicant need beyond the standard Startup India form?
A: Beyond the incorporation certificate and business write-up every Startup applicant provides, a Deep Tech applicant must submit documents and information demonstrating each of the four attributes in clause 1(n), typically an R&D expense schedule, patent or IP filing records, a commercialisation roadmap, and a memo addressing technical or scientific uncertainty and development timelines (Notification G.S.R. 108(E), clause 2(i)(c)).

Q: Does Deep Tech recognition change anything for a startup with foreign investors or an overseas holding structure?
A: The notification itself does not alter FEMA rules on foreign investment, and a gap from the 2019 framework carries over unchanged. The Foreign Exchange Management (Non-debt Instruments) Rules, 2019 recognise only startup companies, not startup LLPs, for foreign investment purposes. A Deep Tech Startup structured as an LLP remains DPIIT-recognised but cannot access instruments reserved for startup companies, such as convertible notes, regardless of its Deep Tech status. Founders choosing between a company and an LLP structure for a deep tech venture with anticipated foreign funding should weigh this gap before incorporation, not after a term sheet is signed.

Q: What happens to Deep Tech recognition if the company undergoes an internal restructuring or a co-founder exit?
A: The notification bars recognition for any entity formed by splitting up or reconstruction of an existing business (Notification G.S.R. 108(E), proviso to clause 1(a)). A co-founder exit alone does not trigger this, but a restructuring designed to create a new entity out of an existing recognised business could jeopardise recognition for the resulting entity, and should be reviewed before execution.

Q: Is Deep Tech a separate registration from regular DPIIT Startup recognition?
A: A Deep Tech Startup is deemed to be a Startup, and references to Startup in the notification include Deep Tech Startup unless stated otherwise (Notification G.S.R. 108(E), proviso to clause 1(n)). In practice, the application is filed on the same DPIIT portal, with additional documentation specific to the Deep Tech attributes layered on top of the standard Startup application.

Q: What happens if DPIIT rejects the Deep Tech application but the entity still qualifies as a regular Startup?
A: A rejected Deep Tech application does not automatically forfeit regular Startup status if the entity independently meets the standard criteria in clause 1(a). Founders should apply for, or retain, regular Startup recognition regardless of the outcome of a separate Deep Tech application.

Q: Do investors verify Deep Tech status during due diligence?
A: Increasingly, yes, particularly for deep tech-focused funds and the Startup India Fund of Funds 2.0, which channels capital toward DPIIT-recognised startups through SEBI-registered AIFs with a stated focus on deep tech. Investors will typically check that the DPIIT certificate, and any 80-IAC certification, is current and was obtained on accurate documentation, since a revoked certificate under clause 6 is deemed never to have been issued.

Q: Does Deep Tech recognition affect ESOP taxation for employees?
A: Not directly through this notification. The ESOP perquisite tax deferral, now under Section 392(3) read with Section 289(3) of the Income Tax Act 2025, extended to 60 months from the end of the relevant tax year for shares allotted on or after 1 April 2026, operates independently of Deep Tech status, though it does require the underlying DPIIT recognition and, where relevant, IMB certification to be valid at the time of allotment.

Q: Can a startup with an NRI founder or foreign shareholding still qualify as a Deep Tech Startup?
A: Yes. The entity type eligibility criteria in clause 1(a) turn on incorporation form, private limited company, LLP, partnership firm, or cooperative society, not on the residency or citizenship of the founders or shareholders. Foreign shareholding is governed separately by FEMA and does not affect Deep Tech eligibility under this notification.

Q: What happens if a Deep Tech certificate is later found to be based on incorrect information?
A: The Inter-Ministerial Board has the authority to revoke a certificate obtained on the basis of false information, and once revoked, the certificate is deemed to have never been issued (Notification G.S.R. 108(E), clause 6). This has retrospective consequences for any tax exemption already claimed on the strength of that certification, which is why documentation accuracy at the time of filing matters more than speed.
