A practical operational guide for year-end GST reviews, covering outward turnover alignment, GSTR-2B credit reconciliations, RCM audits, LUT renewals, and new fiscal cycle preparations.

GST COMPLIANCE CHECKLIST

Year-End Review & Regulatory Action Plan

Introduction

As the financial year draws to a close, structured and meticulous planning is essential for businesses to navigate their statutory obligations seamlessly. Ensuring comprehensive Goods and Services Tax (GST) compliance at year-end not only prevents costly interest liabilities and punitive penalties but also safeguards eligible Input Tax Credits from forfeiture. This checklist provides a systematic framework to review reconciliations, manage annual adjustments, and prepare your operational workflows for the upcoming fiscal cycle.

Comprehensive Year-End GST Compliance Checklist

1. Outward Supply and Turnover Alignment

Review sales figures to uncover any variance between total taxable turnover or output tax liability declared across GSTR-3B and GSTR-1, ensuring complete alignment with underlying financial ledgers. Document any identified mismatches so they can be rectified through adjustments in subsequent return filings.

2. Input Tax Credit (ITC) Verification & Reconciliation

Cross-verify the tax credits claimed in financial books and GSTR-3B against GSTR-2B to confirm validation, and ensure the closing balance in the Electronic Credit Ledger corresponds with ledger records. Process any unclaimed credits visible on the portal through the March return, while coordinating with vendors regarding any missing entries in GSTR-2B to secure eligible claims. Identify and reverse credit previously claimed on barred categories (such as personal-use vehicles, staff welfare expenses, or composition supplies). Complete mandatory annual credit reversals where applicable pursuant to Rule 42 and Rule 43 of the CGST Rules. Retract credit via the March GSTR-3B for invoices where vendor payments remain unsettled beyond 180 days, reclaiming the amount subsequently upon settling the dues.

3. Reverse Charge Mechanism (RCM) Audit

Validate compliance regarding inbound supplies subject to reverse charge obligations (including legal counsel, premises rental, director compensation, sponsorship arrangements, and freight transport services). Reconcile RCM tax liabilities recorded in books against actual disbursements reported in GSTR-3B, ensuring any pending dues are accounted for in the March returns.

4. Letter of Undertaking (LUT) Submission

File the LUT application on the common portal ahead of the upcoming fiscal cycle to facilitate zero-rated exports without upfront tax payment.

4. Pending Refund Proceedings

Review all open refund eligibility windows and file pending claims within the statutory two-year timeframe prescribed under regulatory provisions.

5. Advance Payments on Service Engagements

Check whether any advance considerations were received for services prior to invoice generation—triggering tax point liability upon receipt—and account for any missed tax adjustments within the March return.

6. Composition Scheme Opt-In

Evaluate aggregate turnover boundaries to determine eligibility for the Composition Scheme, submitting Form CMP-02 where applicable.

7. Quarterly Return Monthly Payment (QRMP) Scheme Management

Review filing frequency preferences for taxpayers below the ₹5 crore threshold; specifically, entities that utilized the QRMP structure up to the quarter ending March and wish to shift to standard monthly filing for the new fiscal year must register their preference.

8. E-Invoicing and Dynamic QR Code Applicability

Review operational turnover metrics and supply types to confirm whether electronic invoicing or dynamic QR code mandates apply, ensuring system readiness and adherence.

9. Profile and Registration Maintenance

Inspect GST registration parameters to guarantee that operational addresses and core business details remain correctly updated on the portal.

10. Fresh Invoice Sequencing

Initialize a fresh numbering sequence for tax invoices starting from the first day of the new financial year to prevent compliance and audit mismatches.

11. HSN and SAC Code Accuracy

Ensure proper classification and reporting of HSN or SAC codes across all B2B and B2C billing to minimize the risk of departmental scrutiny or queries.

Conclusion

Adhering diligently to this comprehensive year-end GST checklist ensures full alignment with applicable statutory frameworks while mitigating exposure to regulatory disputes and financial penalties. Proactive execution of these reconciliations and filings lays a robust foundation for seamless corporate operations in the new financial year.
