March 31st Deadline: 5 Accounting Tasks That Could Cost You Thousands (If You Miss Them)

Final Call: March 31st Is The Reporting Deadline

When it comes to Indian accounting and finance, March 31st stands out as the most significant date. With the end of the financial year 2025-26, Indian businesses are making sure their financial statements are clean, their taxes are settled, and their compliance boxes are ticked. Accounting professionals are swamped, and BBA and MBA students get to learn a valuable lesson in the management of finances.

n this scenario, a single day can be devastating financially, whether it be the cost of a missing checkbox, a critical bank reconciliation that will determine your company’s profitability for the entire year and beyond, etc. That’s March Closing for you. In this article, I have compiled a list of 5 tasks that need to be completed before the end of the day, March 31, 2026, and the closure of the March 2026 financial statements.

1. The Foundation: Comprehensive Bank & GST Reconciliation

The most common reason for audit observations is a mismatch between the company’s books and external records. Before closing the year, you must perform a “Three-Way Match” between your internal ledger, bank statements, and the GST portal.

Key Action Points:

• Bank Reconciliation Statement (BRS): Ensure every entry in your bank statement is accounted for in your books. Unreconciled cheques or bank charges can lead to incorrect cash balance reporting.
• GSTR-2B vs. Purchase Register: Reconcile the Input Tax Credit (ITC) available in your GSTR-2B with your purchase invoices. If a supplier hasn’t uploaded an invoice, follow up immediately to avoid losing your credit.
• Sales Reconciliation: Match your GSTR-1 and GSTR-3B data with your sales register to ensure no revenue has been missed or double-counted.

2. Tax Compliance: Advance Tax & TDS Finalization

March is the Month of the Income Tax Depart. If you have not pre-paid your correct amount of taxes by the due date, the Income Tax Act, sections 234B and 234C, will charge you interest.Main Action Items:

Key Action Points:

• Final Installment of Advance Tax: Ensure that 100% of your estimated tax liability for FY 2025-26 is paid by March 15th (or by March 31st with minimal interest).
• TDS/TCS Reconciliation: Verify that all Tax Deducted at Source (TDS) on payments like rent, professional fees, and salaries has been deposited. Check your Form 26AS and AIS (Annual Information Statement) to ensure all taxes paid are correctly reflected against your PAN.
• Investment Proofs: For students and salaried professionals, this is the last chance to submit investment proofs (80C, 80D, etc.) to your employer to reduce your tax burden.

3. Inventory & Fixed Asset Verification

The only means to verify that the “Stock in Hand” reflected in the Balance Sheet is that stock audits confirm the existence of stock. This is what we call a “classic example of Internal Control” in the case of BBA Students.

Key Action Points:

• Physical Stock Take: Conduct a physical count of inventory on the night of March 31st. Account for any damages, slow-moving items, or obsolescence by creating necessary provisions.
• Fixed Asset Register (FAR): Verify that all assets purchased during the year are correctly capitalized and depreciation is calculated as per the Companies Act and Income Tax Act.
• Write-offs: Identify any bad debts or unusable assets that need to be written off to present a “true and fair” view of the business.

4. Provisions and Accruals: Closing the “Gap”

By the accrual basis of accounting, an expense must be recorded when the expense is incurred as opposed to when the expense is paid. Most businesses overlook “invisible” expenses that are incurred in the current financial year.

Key Action Points:

• Outstanding Expenses: Create provisions for electricity bills, telephone bills, and salaries for March, even if they are paid in April.
• Prepaid Expenses: Identify payments made for the next financial year (like insurance premiums or annual software subscriptions) and move them to “Prepaid Expenses” in the Balance Sheet.
• Audit Fee Provision: Don’t forget to provide for the statutory audit fees for the year-end audit.

5. Audit Readiness: Organizing the “Trail”

In 2026, audits are increasingly becoming “Invisible” and AI-driven. To survive an audit, your digital and physical documentation must be flawless.

Key Action Points:

• Vouching & Verification: Ensure every journal entry has a supporting document (invoice, receipt, or contract).
• Agreement Reviews: Check for any contracts or leases expiring on March 31st that need renewal or termination.
• Digital Backup: Securely back up your accounting data. With the government’s focus on “Audit Trails” (Edit Log), ensure your software compliance is up to date.
