The words "tax audit" sound scary. They shouldn't. A tax audit is not a government investigation into your business.
It simply means this: once your business or profession crosses a certain size, a Chartered Accountant (CA) has to check your accounts and sign off on them before you file your tax return. The CA confirms your books are in order and reports a few details the tax department asks for. That's all it is.
Below: who actually needs an audit, what the CA checks, the deadlines, and how to make it quick and cheap. Need one this year? Our audit team handles the whole thing.
Who needs a tax audit in FY 2026–27
The triggers under Section 44AB:
| Who | Audit threshold | Digital-receipts relief |
|---|---|---|
| Business | Turnover > ₹1 crore | ₹10 crore if 95%+ cashless |
| Professionals | Receipts > ₹50 lakh | — |
| Presumptive opt-out | Income below presumptive rate & above basic exemption | — |
| Cooperative societies | Income > ₹1 crore | — |
The digital channel exception matters: A business with ₹8 crore turnover but 97% cashless transactions is exempt from mandatory audit. This incentivises digital payment adoption and is worth structuring your payment collection around if you're near the threshold.
What the auditor actually examines
The audit report is a long checklist. The CA isn't judging whether your business is good or bad — they're just confirming the facts on the things the tax department cares about, such as:
- How you record income — on a cash basis or accrual basis — and whether that changed during the year
- Gross turnover/receipts and the basis of their computation
- Purchases and sales reconciliation
- Any cash payments above ₹10,000 (these aren't allowed as a business expense)
- TDS compliance — amounts deducted, deposited and reported
- Brought-forward losses, depreciation, and capital gain details
- Loans or deposits above ₹20,000 taken or repaid in cash
- Payments to related parties (family members or sister companies)
The quality of your books determines how smooth this process is. Well-maintained, reconciled accounts mean the auditor spends a day or two; messy, incomplete records can stretch the process and increase the cost.
Key deadlines for FY 2026–27
| Filing | Due date |
|---|---|
| Audit report (3CA/3CB + 3CD) | 30 Sep 2027 |
| ITR for audit cases | 31 Oct 2027 |
| Transfer-pricing audit (3CEB) | 31 Oct 2027 |
| Late-filing penalty | 0.5% of turnovercapped at ₹1.5 lakh |
More importantly, you cannot file your ITR without the signed report — so a missed audit deadline cascades into a missed ITR deadline.
How to prepare: the practical checklist
The businesses that finish audits quickly and cheaply share one habit: they keep their books current through the year rather than reconstructing them in July and August. The practical checklist:
- Reconcile your bank statements monthly through the financial year, not at year-end
- Maintain a cash book if you have cash transactions — and avoid cash payments above ₹10,000 to any single party
- Track fixed assets with acquisition dates and costs for the depreciation schedule
- Reconcile TDS deducted and deposited — Form 26AS mismatches are a common audit finding
- File GST returns on time — the auditor will reconcile your ITR turnover against GST returns, and discrepancies require explanation
- Appoint your CA by June — don't wait until September when every CA in the country is running 10 simultaneous audits
Frequently asked questions
Is a tax audit the same as an income tax scrutiny?
No. A tax audit (Section 44AB) is a proactive statutory requirement conducted by your own CA before you file your return. A scrutiny (Section 143(3)) is when the income tax department selects your return for examination after you've filed it. They're completely different in nature and trigger.
Can I use the same CA who does my regular accounting?
Yes, a practising CA can conduct the tax audit for their own client. There's no independence requirement under the Income-tax Act the way there is under the Companies Act for statutory audits.
What happens if I miss the 30 September deadline?
You'll face a penalty and be unable to file your ITR on time. The department can levy 0.5% of turnover as penalty, though genuine hardship cases can apply for waiver. The cascading ITR delay also brings its own late-filing fee under Section 234F.
My turnover is just above ₹1 crore but most of it is digital. Do I need an audit?
Not if at least 95% of your receipts and at least 95% of your payments (including all expenses) are through banking channels. If both conditions are met, the threshold rises to ₹10 crore and you're exempt from the mandatory audit.
Audit season is September. Don't wait until August. Our team handles your tax audit end to end — books reconciliation, Form 3CD preparation and CA sign-off — so your ITR is filed well before the October deadline.
