Tax Audit Checklist for AY 2026-27: Getting Form 3CD Ready Before 30 September
If your business or profession crossed the Section 44AB limits in FY 2025-26, your Chartered Accountant must upload the audit report by 30 September 2026, and your audited return is due by 31 October 2026. This checklist covers who needs the audit, what to hand over, and the Form 3CD clauses that most often hold reports up.
Why it matters
A Tax Audit Is More Than a Formality
Form 3CD is a 44-clause statement in which your auditor reports how your books line up with the Income-tax Act. The department's systems compare it with your GST returns, TDS statements and Annual Information Statement (AIS), so gaps in a rushed report can come back as questions later.
It's a legal requirement
Missing 30 September can mean a penalty of 0.5% of turnover, up to ₹1.5 lakh.
Mismatches are flagged by systems
Turnover in Form 3CD, GST returns and AIS is compared automatically. Unexplained differences can lead to notices.
It shapes next year's return
Depreciation, disallowances and losses reported now carry into next year's tax computation.
Banks read it
Lenders reviewing working-capital limits often ask for the tax audit report along with audited accounts.
Who needs a tax audit for FY 2025-26
This year's audit is still governed by Section 44AB of the Income-tax Act, 1961. Turnover here means total sales or gross receipts for the year, not profit.
| Your situation | Tax audit is required when |
|---|---|
| Business, normal case | Turnover or gross receipts exceed ₹1 crore |
| Business where cash receipts and cash payments are each within 5% of the total | Turnover exceeds ₹10 crore |
| Profession (doctors, architects, engineers, lawyers, consultants and others) | Gross receipts exceed ₹50 lakh |
| Business that opted for presumptive tax (Section 44AD) in any of the last five years | You now declare profit below the presumptive rate and your income exceeds the basic exemption limit |
| Profession under presumptive tax (Section 44ADA) | You declare profit below 50% of receipts and your income exceeds the basic exemption limit |
Section 44AD covers businesses with turnover up to ₹3 crore, and Section 44ADA covers professionals with receipts up to ₹75 lakh, where cash receipts are within 5% of the total. Otherwise the limits are ₹2 crore and ₹50 lakh.
Share and F&O traders: turnover for futures and options is the total of profits and losses on each trade, ignoring whether each is a profit or a loss. It is not the contract value. Most traders' turnover is much lower than they expect, and because trades are digital, the ₹10 crore limit usually applies. Work out the figure before deciding either way.
Key dates for AY 2026-27
| What | Due date |
|---|---|
| Tax audit report (Form 3CA or 3CB, with Form 3CD) | 30 September 2026 |
| Income-tax return for audit cases | 31 October 2026 |
| Audit report where a transfer pricing report (Form 3CEB) is also required | 31 October 2026 |
| Income-tax return for transfer pricing cases | 30 November 2026 |
As of early September 2026, the CBDT had not extended the 30 September date, although professional bodies had asked for more time. Plan for 30 September and treat any extension as a bonus.
After your CA uploads the report, you must accept it from your own login on the income-tax portal. Until you do, it isn't treated as furnished, so keep your login details handy in the last week of September. For companies, the statutory audit under the Companies Act comes first, and the tax audit report in Form 3CA is based on those audited accounts.
Documents to hand over to your auditor
Most delays come from missing reconciliations, not from the audit itself. Share these early:
Books and accounts
- Final trial balance, profit and loss account and balance sheet
- Bank statements and reconciliations for every account
- Cash book and year-end cash balance
- Fixed asset register with bills and put-to-use dates
- Closing stock statement and valuation method
GST records
- GSTR-1 and GSTR-3B for all 12 months
- GSTR-2B and input tax credit reconciliation
- Turnover reconciliation across books, GST returns and AIS
- E-invoice and e-way bill reports, if applicable
TDS and advance tax
- FY 2025-26 TDS and TCS returns (24Q, 26Q, 27Q, 27EQ)
- TRACES default or justification reports
- Advance tax and self-assessment tax challans
- Form 26AS, AIS and TIS
Loans and related parties
- Loan confirmations and interest certificates
- Any loan, deposit or repayment made in cash
- List of relatives and related concerns, with transactions
MSME suppliers and payroll
- Udyam status of suppliers, with invoice and payment dates
- PF and ESI challans showing deposit dates
- Salary, bonus and gratuity workings
Last year's file
- Previous year's return and tax audit report
- Losses and depreciation carried forward
- Pending assessments, demands or refunds
Form 3CD clauses that most often cause delays
These clauses need information that isn't in the trial balance, so start on them first.
Clause 44: GST break-up of expenses
Expenses are split between registered suppliers (regular and composition), unregistered suppliers and exempt purchases. Tag each vendor's GST status in your accounting software to avoid doing this by hand.
Clause 34: TDS compliance
Payments liable to TDS are listed with the amounts deducted and deposited. Where TDS wasn't deducted or paid, 30% of the expense can be disallowed under Section 40(a)(ia).
Clauses 22 and 26: MSME dues and Section 43B
Micro and small suppliers must be paid within 15 days, or up to 45 days under a written agreement (Section 43B(h)). Late amounts are allowed only in the year of payment and are reported with other Section 43B dues. Clause 22 covers interest payable to MSMEs.
Clause 31: Cash loans and receipts
Loans or deposits of ₹20,000 or more taken or repaid in cash (Sections 269SS and 269T) are listed, as are cash receipts of ₹2 lakh or more from one person in a day or for one transaction (Section 269ST). Each carries a separate penalty.
Clause 21: Disallowances
Cash payments above ₹10,000 to one person in a day (₹35,000 for transporters) are disallowed under Section 40A(3). Personal, capital and penal expenses charged to profit and loss are reported here too.
Clause 20(b): Late PF and ESI deposits
Employees' contributions deposited after the due date under the PF or ESI law aren't deductible at all under Section 36(1)(va), even if paid before you file your return.
Clause 35: Quantitative details
Traders and manufacturers report opening stock, purchases, sales, closing stock and any shortage or yield for principal items. Production and consumption records need to be ready.
Clause 18: Depreciation
Additions are reported with dates. Assets put to use for less than 180 days in the year get half the normal rate, so keep bills and installation dates on file.
Penalties for missing the date
| Default | Consequence |
|---|---|
| Audit report not furnished by 30 September | Penalty under Section 271B of 0.5% of turnover or gross receipts, up to ₹1.5 lakh. It can be waived if you show reasonable cause (Section 273B). |
| Report uploaded but not accepted by you | The report isn't treated as furnished, and the return can be treated as defective. |
| Return filed after 31 October | Late fee of up to ₹5,000, interest at 1% a month on unpaid tax, and business or capital losses of the year can't be carried forward. |
What changes from next year
The Income-tax Act, 2025 took effect on 1 April 2026, but your FY 2025-26 audit is still done under the 1961 Act, on Forms 3CA or 3CB and 3CD, using the old section numbers (for example, 194C and 194J in the TDS clause).
From tax year 2026-27, a single new Form 26 replaces these forms, with the first reports due by 30 September 2027. The annual tax statement also becomes Form 168 instead of Form 26AS. Most checks carry over, so the habits in this checklist, such as monthly GST and TDS reconciliation, dated asset registers and clean MSME payment records, will make that first Form 26 audit easier.
This guide is general information on Indian tax and corporate law as it stood on 11 September 2026, and is not advice for any particular case. Rules, due dates and forms change, and how they apply depends on your facts. Please confirm the current position before acting, or speak to a qualified professional.
Common situations
Tax Audit Situations Common in Vadodara
Every business is different, but these patterns come up often across the city's industries.
GIDC manufacturing units
Units in Makarpura, Por, Waghodia, Savli and Nandesari need quantitative stock details, stock valuation and MSME payment tracking for Section 43B(h).
Traders and distributors
Wholesale and retail businesses around Raopura, Mandvi and Sayajigunj often handle cash, so Section 269ST receipts, Section 40A(3) payments and GST turnover matching need attention.
Doctors, consultants and other professionals
Clinics and practices cross the ₹50 lakh receipts limit sooner than expected. Section 44ADA can apply up to ₹75 lakh where receipts are mostly digital.
Share and F&O traders
Turnover is worked out trade by trade. Many traders stay under the limit, but carrying losses forward depends on filing the return on time.
Frequently asked questions
Answers to Your Tax Audit Questions
What is the tax audit due date for AY 2026-27?
The tax audit report for FY 2025-26 is due by 30 September 2026, and the audited income-tax return by 31 October 2026. If you also need a transfer pricing report (Form 3CEB), the audit report is due by 31 October and the return by 30 November 2026. These dates apply unless the CBDT notifies an extension.
My turnover is ₹4 crore but nearly all receipts are digital. Do I need a tax audit?
Probably not under the turnover test. If cash receipts and cash payments are each within 5% of the totals, the limit rises to ₹10 crore. Check both sides, because cash paid to suppliers or labour counts too. An audit can still apply if the presumptive-tax rules cover you.
What is the difference between Form 3CA and Form 3CB?
Form 3CA is used when your accounts are already audited under another law, such as companies under the Companies Act or LLPs with turnover above ₹40 lakh or contribution above ₹25 lakh. Form 3CB is used for everyone else, such as proprietors and partnership firms. Both are filed with Form 3CD.
What happens if I miss the 30 September deadline?
A penalty of 0.5% of turnover, up to ₹1.5 lakh, can be levied under Section 271B unless you show reasonable cause. File as soon as possible, because your return also depends on the report.
Does the new Income-tax Act, 2025 change this year's audit?
No. FY 2025-26 (AY 2026-27) audits use Forms 3CA, 3CB and 3CD and the 1961 Act's section numbers. The new Form 26 applies from tax year 2026-27, with the first reports due in September 2027.
How long does a tax audit take?
It depends on how ready your books are. When the trial balance is final and bank, GST and TDS reconciliations are done, the audit moves quickly. Most delays come from pending reconciliations, missing loan confirmations or unexplained GST differences, so share documents early.
