A Financial Year-End Checklist for Indian Businesses in 2026

As the financial year comes to an end, many businesses focus only on closing their books. But year-end is more than accounting. It is the right time to verify compliance, fix mismatches, and prepare for income tax filing.

A handful of checks before March 31 helps you avoid compliance gaps, reduces stress, and keeps you prepared for filing.

1. Reconcile Your GST Returns

GST reconciliation is one of the most important year-end activities.

Before closing the year, verify that:

• GSTR-1 matches with GSTR-3B
• Input Tax Credit (ITC) matches with GSTR-2B
• All sales and purchase invoices are properly recorded

Even small mismatches can trigger notices from the GST department. Monthly reconciliation is ideal; a financial year-end review is essential.

2. Review Advance Tax Liability

Advance tax applies if total tax liability exceeds Rs. 10,000 in a financial year.

Under Section 208 of the Income Tax Act, 1961, individuals and businesses must pay advance tax in instalments during the year.

Failure to pay the correct advance tax may result in interest under:

• Section 234B: interest for non-payment of advance tax
• Section 234C: interest for deferment of advance tax

Reviewing your tax liability before March 31 helps avoid unnecessary interest.

3. Verify TDS Compliance

Businesses that deduct TDS must ensure compliance before the year ends.

Important checks include:

• TDS deducted correctly on applicable payments
• TDS deposited within prescribed timelines
• Quarterly TDS returns filed accurately

Delays or errors may attract interest and penalties under the Income Tax Act.

4. Update Your Books of Accounts

Accurate books of accounts are the foundation of compliance.

Before the financial year closes:

• Record all expenses and revenue
• Update outstanding receivables and payables
• Reconcile bank accounts and credit cards
• Ensure supporting documents are maintained

Clean records make ITR filing, audits, and financial planning much easier.

5. Review Business Expenses and Deductions

Year-end is the right time to review allowable business expenses, including office rent, utilities, professional fees, business travel, and software costs.

Deductions must be supported by proper documentation. Missing invoices or incorrect records may lead to disallowance during assessment.

6. Check Vendor Compliance for GST

Your Input Tax Credit depends on vendor compliance.

Before the financial year closes, verify that:

• Vendors have filed their GST returns
• Your ITC appears correctly in GSTR-2B
• Vendor GSTIN details are accurate

If vendors fail to file returns, your ITC eligibility may be affected.

7. Prepare for Income Tax Return Filing

Preparing early for ITR filing saves time and reduces errors.

Start organising key documents such as:

• Profit and loss statements
• GST records
• TDS certificates (Form 16 / 16A)
• Investment and deduction proofs

Why Financial Year-End Planning Matters

A proper year-end review helps identify errors before filing, reduce your exposure to penalties and interest, and maintain clean financial records for accurate ITR filing.

Businesses that follow a structured review process rarely face unexpected compliance issues.

Frequently Asked Questions

What is the last date for advance tax for a financial year?

The final instalment is due on 15 March, by which 100% of the year's advance tax must be paid. Businesses under presumptive taxation in Section 44AD or 44ADA can pay the entire amount in one instalment by 15 March. Tax paid up to 31 March is still treated as advance tax, but interest under Section 234C applies for the shortfall.

Until when can I claim input tax credit missed in FY 2025-26?

Under Section 16(4) of the CGST Act, ITC for invoices of a financial year can be claimed up to 30 November of the next year or the date of filing the annual return, whichever is earlier. For FY 2025-26 that means claiming it in a GSTR-3B filed by 30 November 2026.

Should I clear MSME supplier dues before 31 March?

Yes, if the supplier is a registered micro or small enterprise. Under Section 43B(h), payments not made within 45 days where there is a written agreement, or 15 days where there is none, are disallowed as an expense in the current year and allowed only in the year of actual payment. Clearing overdue bills before 31 March protects the deduction.

What happens if I forgot to deduct TDS on an expense during the year?

Under Section 40(a)(ia), 30% of an expense paid to a resident is disallowed if TDS was not deducted or not deposited by the ITR due date. Deduct and deposit the TDS with interest before filing the return to avoid the disallowance, and include the entry in the Q4 TDS return due on 31 May.

What year-end checks matter for stock and cash balances?

Physically count closing stock on 31 March and value it at the lower of cost or net realisable value, since it directly affects profit. Reconcile the cash book with actual cash and all bank accounts with statements. Large cash balances or unexplained stock differences are common triggers for questions in scrutiny and GST audits.
