Form 3CD Checklist for AY 2026-27: Practical Tax Audit Review
Use this practical Form 3CD checklist to organise tax audit work for AY 2026-27, from depreciation and MSME reporting to TDS, GST and cash-transaction checks.
Form 3CD is easier to complete when the audit team works from a structured checklist instead of opening each clause only at the final filing stage.
For AY 2026-27, tax audit continues under the Income-tax Act, 1961 and the existing Form 3CA/3CB with Form 3CD framework remains applicable.
1. Start with the entity master
- PAN, address, constitution and nature of business or profession;
- partners or members, where relevant;
- books maintained and locations;
- method of accounting;
- inventory valuation method; and
- presumptive-tax history where relevant.
Errors in basic master information often flow into both the return and audit report, so this stage should not be treated as clerical.
2. Complete Trial Balance and financial statement review
Reconcile the final Trial Balance with the Balance Sheet, P&L and Notes to Accounts.
Check opening balances, prior-year comparatives, capital accounts, loans, trade balances, inventory, fixed assets and year-end provisions.
3. Prepare tax depreciation independently
Book depreciation and income-tax depreciation are separate computations.
The tax working should identify opening WDV, additions, put-to-use dates, deletions, applicable blocks and closing WDV. Pay particular attention to additions used for less than 180 days.
4. Review MSME and Section 43B items
Obtain vendor-wise MSME information early. Identify micro and small suppliers, payment terms, acceptance dates, year-end outstanding amounts and subsequent payments.
Also review other Section 43B liabilities and specified statutory dues.
5. Reconcile TDS and TCS
- expense ledgers vs applicable TDS categories;
- deductions vs challans;
- quarterly statements vs books;
- year-end provisions;
- short or non-deduction cases; and
- partner-payment TDS where applicable.
6. Review specified payments and transactions
Check cash payments, loans and deposits, repayments, cash receipts and other transactions covered by the prescribed reporting clauses.
Do not rely only on ledger names. Bank books, journal entries and party ledgers may contain reportable transactions that are not obvious from the Trial Balance.
7. Reconcile GST information
Reconcile turnover between books and GST returns and document timing differences, credit notes, exports, exempt supplies and other adjustments.
Prepare Clause 44 expenditure classification from a controlled data set rather than reconstructing it manually at the filing stage.
8. Maintain an exceptions register
A good tax audit file should clearly separate:
- completed items;
- items awaiting client evidence;
- management representations;
- auditor observations; and
- items requiring tax-computation adjustment.
Reduce preparation work before the review starts
When financial statements are still being rebuilt in Excel, the tax audit team loses time updating the same figures in multiple places.
assureOffice Financial Builder can prepare structured financial statements from Tally or traditional Excel data so the team can focus on audit clauses and professional review.
For a detailed MSME review, see Clause 22 and Section 43B(h).
The most efficient Form 3CD workflow starts with clean books, stable financial statements and reconciled supporting schedules.
