Every September, business owners discover — usually from their bank or a WhatsApp forward — that they may need a tax audit they have never planned for. The rules are threshold-driven and the thresholds changed shape over recent years, so most of what circulates is partly wrong. Here is the position for AY 2026-27 (FY 2025-26), as it applies to returns being filed right now.
Short answer
Short answer: a business needs a tax audit under Section 44AB when turnover for FY 2025-26 exceeds ₹1 crore — relaxed to ₹10 crore only if both cash receipts and cash payments stayed within 5% of the respective totals. A profession needs one when gross receipts exceed ₹50 lakh. The audit report (Form 3CA/3CB with 3CD) is due 30 September 2026, and the audit-case ITR follows by 31 October 2026. Presumptive taxation under 44AD/44ADA can lawfully keep you out of audit entirely — and quietly pull you into one if you exit it wrongly.
| Who you are | Audit trigger for AY 2026-27 |
|---|---|
| Business (normal) | Turnover above ₹1 crore |
| Business, cash receipts AND payments each ≤ 5% | Turnover above ₹10 crore |
| Profession (doctors, consultants, architects, CAs…) | Gross receipts above ₹50 lakh |
| 44AD presumptive business (declaring 8%/6% or more) | No audit up to the 44AD ceiling — ₹3 crore with ≤5% cash |
| 44ADA presumptive professional (declaring 50% or more) | No audit up to ₹75 lakh with ≤5% cash (else ₹50 lakh) |
| Left presumptive after using it — 44AD(4) trap | Audit if income exceeds the basic exemption limit |
Business — ₹1 crore or ₹10 crore?
The base limit is ₹1 crore of sales, turnover or gross receipts. The ₹10 crore limit is not a general increase — it is a reward for going digital, and it needs BOTH conditions in the same year:
- Aggregate cash receipts during FY 2025-26 did not exceed 5% of total receipts, AND
- Aggregate cash payments did not exceed 5% of total payments.
- Fail either side — one property purchase paid partly in cash, one big supplier settled in currency — and the limit snaps back to ₹1 crore for the whole year.
- Cheques and bank drafts that are NOT account-payee count as cash for this test — a detail that surprises traders every year.
Profession — ₹50 lakh, and the ₹75 lakh myth
For professionals the audit trigger is ₹50 lakh of gross receipts — and the ₹10 crore digital relaxation does not apply to professions. The ₹75 lakh figure floating around is something else entirely: it is the ceiling for 44ADA presumptive taxation (where at least 95% of receipts are digital), not a raised audit threshold. A consultant with ₹60 lakh of receipts who opts for 44ADA and declares 50% needs no audit; the same consultant staying on regular books has crossed ₹50 lakh and needs one. Same income, different paperwork, opposite audit outcomes.
The presumptive escape — and its trap
- 44AD (businesses): declare 8% of turnover (6% for digital receipts) or more, up to a ₹3 crore ceiling with ≤5% cash — no books audit required.
- 44ADA (professionals): declare 50% of gross receipts or more, ceiling ₹75 lakh with ≤5% cash — no audit required.
- The trap — 44AD(4): once you use 44AD and then declare LOWER than the presumptive rate in a later year (within the five-year lock-in), you must maintain books and get audited if your income exceeds the basic exemption limit. Many audits in September are of small businesses that exited presumptive without realising this.
- Choosing between presumptive and regular books is a numbers decision — real margin vs deemed margin, loss years, partner remuneration — worth an hour with a CA before the year closes, not after.
Due dates for AY 2026-27
| Filing | Due date |
|---|---|
| Tax audit report — Form 3CA/3CB with annexure 3CD | 30 September 2026 |
| ITR for audit cases | 31 October 2026 |
| ITR with transfer-pricing report (Form 3CEB) | 30 November 2026 |
| Non-audit business ITR-3/ITR-4 (already gone) | 31 August 2026 |
The audit report is uploaded by the auditor and then accepted by you on the portal — both steps must finish by the due date, so handing your CA the books in the last week of September is a plan for penalty, not for filing. Books, ledgers, GST returns, TDS statements and loan confirmations should reach the auditor by early September.
Forms 3CA / 3CB / 3CD — and UDIN
- Form 3CA applies when your accounts are already audited under another law (companies audited under the Companies Act).
- Form 3CB applies to everyone else — proprietorships, partnerships, LLPs without statutory audit.
- Form 3CD is the 40-plus-clause annexure both attach — loans in cash, TDS defaults, GST reconciliation, related-party payments all get reported here. It is where scrutiny cases are born.
- Every report carries a UDIN generated by the signing CA — verifiable on the ICAI portal. No UDIN, no valid audit.
Penalty for missing the audit
Section 271B: half a percent (0.5%) of turnover or gross receipts, capped at ₹1,50,000. The penalty can be waived for reasonable cause — auditor's resignation, natural calamity, genuine system failure — but "we were busy" is not reasonable cause. The quieter cost is worse: an audit-case return filed without the audit report invites processing failure, interest under 234A on unpaid tax, and a much higher chance of scrutiny selection.
Frequently Asked Questions
What is the tax audit limit for AY 2026-27?
For businesses: ₹1 crore of turnover, relaxed to ₹10 crore when both cash receipts and cash payments stayed within 5% of the respective totals for FY 2025-26. For professions: ₹50 lakh of gross receipts, with no digital relaxation. Presumptive taxpayers under 44AD/44ADA below their ceilings need no audit at all.
Is the tax audit limit for professionals ₹50 lakh or ₹75 lakh?
The audit trigger is ₹50 lakh of gross receipts. ₹75 lakh is the ceiling for opting into Section 44ADA presumptive taxation when at least 95% of receipts are digital — a professional inside 44ADA declaring 50% or more needs no audit even between ₹50-75 lakh. The two limits answer different questions.
What is the due date for tax audit for AY 2026-27?
The audit report (Form 3CA/3CB with 3CD) is due by 30 September 2026, and the income tax return for audit cases by 31 October 2026. Transfer-pricing cases get until 30 November. Both the auditor's upload and your acceptance on the portal must happen within the deadline.
Does the ₹10 crore limit apply if I received some payments in cash?
Yes, as long as aggregate cash receipts stayed within 5% of total receipts AND aggregate cash payments stayed within 5% of total payments. Cross either 5% line and the limit reverts to ₹1 crore for the whole year. Note that non-account-payee cheques and drafts count as cash for this test.
I used 44AD last year but want to declare lower profit this year. Do I need an audit?
Probably. Under Section 44AD(4), opting out of presumptive within the five-year lock-in bars you from 44AD for five years, and if your income exceeds the basic exemption limit you must maintain books and get audited under 44AB(e). This is the most common accidental audit trigger for small businesses.
What is the penalty for not getting a tax audit done?
Section 271B levies 0.5% of turnover or gross receipts, capped at ₹1,50,000. It can be dropped for reasonable cause, but routine delay does not qualify. The indirect costs — defective return processing, 234A interest, higher scrutiny probability — usually exceed the penalty itself.
What documents does the auditor need, and by when?
Books of account, bank statements, GST returns (GSTR-1/3B) with reconciliation, TDS returns and Form 26AS/AIS, loan statements and confirmations, stock records and fixed-asset details. For a 30 September deadline, complete records should reach the auditor by early September — the 3CD annexure alone has over 40 clauses to verify.
Do you handle tax audits in Ahmedabad?
Yes — tax audit under Section 44AB is core work at Pujara & Co (ICAI FRN 141156W), alongside statutory and internal audits. We review your trial balance first and confirm the complete fee in writing before the engagement begins. With the 30 September 2026 deadline approaching, earlier is better.
