    GST, or Goods and Services Tax, has significantly transformed the Indian tax landscape. However, staying compliant with its intricate rules and regulations can be a daunting task for businesses of all sizes. To help you streamline your GST compliance efforts, we’ve created a comprehensive checklist and calendar for 2025.

    Why GST Compliance Matters

    The Goods and Services Tax (GST) is a crucial aspect of India’s tax regime, ensuring seamless taxation across states. Non-compliance can lead to fines, interest charges, and legal scrutiny. Therefore, staying on top of deadlines and maintaining accurate records is vital for businesses of all sizes.

    • GST Registration: Ensure your business is registered under GST if your annual turnover exceeds the prescribed threshold.
    • Tax Invoice Issuance: Issue accurate tax invoices for all sales and purchases, including GSTIN, HSN code, and applicable tax rates.
    • Return Filing: Regularly file GST returns (GSTR-1, GSTR-3B, and GSTR-9) within the specified deadlines.
    • Record Keeping: Maintain detailed records of all GST-related transactions for a minimum of six years.
    • Reconciliation: Reconcile your GST returns with your financial records to ensure accuracy.
