If your business is subject to a tax audit, your income-tax return is usually due on 31 October following the financial year, and the date is close. This guide explains who falls in this group, what to have ready, and the mistakes that cause late fees and notices. The key point: an income tax return for audit cases cannot be filed until the audit report is on the portal.
Who files an income tax return for audit cases?
Broadly, a business or profession whose accounts must be audited under section 44AB of the Income-tax Act files this return by the audit-case due date. Common triggers are turnover above the prescribed limit, or claiming profit lower than the presumptive rate while income is above the basic exemption limit. The thresholds depend on your cash-transaction share and on whether you opted for presumptive taxation, so confirm your own position with your chartered accountant (CA).
Partners in a firm whose accounts need an audit, and working partners in particular, are generally covered by the same extended date. Salaried individuals with no business income are not.
The usual due date, and why you should check for extensions
The statutory default for audit cases (without a transfer pricing report) is 31 October of the assessment year. Companies and firms with international or specified domestic transactions have a later date, usually 30 November. The Central Board of Direct Taxes (CBDT) sometimes extends dates by notification, so check incometax.gov.in before you plan around the deadline. Do not assume an extension will arrive.
Step 1: confirm the tax audit report is filed
The audit report (Form 3CA-3CD or 3CB-3CD) is normally due a month before the return, on 30 September. It is uploaded by the CA, and you must accept it on the e-filing portal. If it is missing, your return cannot be processed as an audit case. Log in, check the status under your pending actions, and chase your CA early if it is still open.
Step 2: finalise your books
The return is only as good as your books. Before you file, make sure:
- All sales and purchase invoices up to 31 March are posted in the correct year.
- Bank, loan and cash balances agree with statements and confirmations.
- Depreciation, provisions and prepaid items are recorded.
- Debtors and creditors are reconciled, and old balances reviewed.
Our guide on bookkeeping checklist for Indian SMEs covers this routine in more detail.
Step 3: match your numbers with the portal
Download Form 26AS and the Annual Information Statement (AIS) from the portal and compare them with your records. Check three things:
- TDS credit: every deduction by your customers should appear against your PAN, and the amount should match your books. If it does not, ask the deductor to correct their TDS return.
- Turnover: compare the sales you report with GST returns. Differences invite questions, so be ready to explain timing or exempt supplies.
- Advance tax and self-assessment tax: confirm the challans are paid and tagged to the right assessment year.
Step 4: pick the right form and fill it carefully
Business income is reported in ITR-3 for proprietors, or ITR-5 for firms and LLPs, and ITR-6 for companies. Use the form that fits your status, not the one you used by habit. The audit information, such as the date of the report and the CA's membership number, must agree with the audit report. Schedules for depreciation, balance sheet and profit and loss need figures that tie out to your financial statements, which should follow the proper format described in our Schedule III explainer for companies.
What happens if you miss the date
- Late fee under section 234F: up to Rs 5,000 for a belated return, or Rs 1,000 if total income is not above Rs 5 lakh.
- Interest under section 234A: 1% per month or part of a month on unpaid tax from the due date.
- Loss of carry-forward: most business losses cannot be carried forward if the return is filed late.
- Separate audit penalty: failing to get the tax audit done or to file the report on time can attract a penalty under section 271B, which is generally 0.5% of turnover capped at Rs 1.5 lakh.
These are general rules. A CA can tell you how they apply to your case, including any reasonable-cause relief.
A simple countdown
WhenWhat to do This weekConfirm the audit report is uploaded and accepted. Next 3-4 daysMatch books with Form 26AS and AIS; fix mismatches. A few days before the due datePay any balance tax, prepare the return, review it with your CA. Before the deadlineFile, then e-verify at once; an unverified return is treated as not filed.Common mistakes to avoid
Most problems are avoidable. Filing with a PAN or bank account that is not pre-validated delays refunds. Reporting turnover that differs from the audit report creates a mismatch the department can see. Claiming deductions without supporting papers is risky, because you may have to prove them later. Forgetting to e-verify within the allowed time means the return is treated as invalid. Keep a folder with the audit report, the filed return, the acknowledgement and the challans, so that you can answer any notice quickly.
