Tax Audit Deadline Is 30 September 2026
Complete these 12 important checks before approving Form 3CD.
Only a few days remain for the tax-audit deadline. Rushing the report without complete records can create differences between the books, Form 3CD and the income-tax return.
Which tax-audit form applies?
| Form | When it generally applies |
|---|---|
| Form 3CA with Form 3CD | When the accounts are already required to be audited under another law, such as the Companies Act. |
| Form 3CB with Form 3CD | When the accounts are not required to be audited under another law but tax audit is applicable. |
12 checks before approving Form 3CD
Finalise the books of account
Ensure that all sales, purchases, expenses, receipts, payments and journal entries are recorded. Avoid changing the books after giving the final data to the auditor without informing the auditor.
Confirm turnover or gross receipts
Reconcile the turnover appearing in the profit and loss account with GST returns, invoices, bank credits and other applicable records.
Complete the GST reconciliation
Compare the books with GSTR-1, GSTR-3B and annual GST workings. Explain differences caused by credit notes, advances, amendments, exempt supplies or timing differences.
Verify TDS compliance
Review expenses such as salary, interest, rent, professional fees, contracts and commission. Check whether applicable TDS was deducted, deposited and reported correctly.
Review outstanding expenses
Examine unpaid statutory liabilities and year-end provisions. Confirm whether any amount requires adjustment or separate reporting under the tax law.
Check MSME creditors
Identify suppliers registered as micro or small enterprises. Keep their declarations, ageing details and payment dates ready for examining the applicable deduction and disclosure requirements.
Verify loans and deposits
Prepare party-wise details of loans accepted or repaid. Include opening balance, additions, repayments, closing balance, mode of payment and lender details.
Check cash transactions
Review large cash receipts, cash payments, expense vouchers and cash-book balances. Confirm that supporting evidence is available and applicable restrictions have been examined.
Update the fixed-asset register
Provide invoices and put-to-use dates for new assets. Record assets sold or discarded and reconcile depreciation with the books and tax workings.
Confirm related-party transactions
Prepare the names, relationships, nature of transactions and amounts involving specified related persons. Keep agreements and supporting documents ready.
Match AIS, TIS and Form 26AS
Review reported income, TDS, high-value transactions and tax payments. Investigate differences before the income-tax return is prepared.
Accept the uploaded report
After the auditor submits the report, the taxpayer should review it on the portal and complete the acceptance process before the deadline.
Documents to keep ready
| Area | Important records |
|---|---|
| Accounts | Trial balance, ledgers, financial statements and schedules |
| Banking | Statements, reconciliations, loan statements and interest certificates |
| GST | GSTR-1, GSTR-3B and turnover reconciliation |
| TDS | Returns, challans, Form 26AS and expense-wise reconciliation |
| MSME | Supplier declarations, registration details, ageing and payment dates |
| Fixed assets | Purchase invoices, sale documents and depreciation workings |
What happens if tax audit is delayed?
Where Section 271B applies, the Assessing Officer may impose a penalty equal to 0.5% of turnover or gross receipts, or ₹1,50,000, whichever is lower.
However, the law provides relief where the taxpayer proves a reasonable cause. This should not be treated as an automatic waiver.
Do not wait for the final day
The auditor needs sufficient time to review reconciliations, supporting records and explanations. The taxpayer also needs time to accept the uploaded report.
Submitting incomplete information on the final day may result in avoidable qualifications, incorrect reporting or last-minute portal difficulties.
