TL;DR
Completing a tax audit does not mean the business’s tax compliance work is finished. Before filing the Income Tax Return, businesses should carefully verify the audited financial statements, tax-audit report, Form 3CD, depreciation, GST and TDS data, brought-forward losses, deductions, advance tax and self-assessment tax. Any discrepancy between the ITR and audited information should be resolved before filing.
Introduction
For businesses subject to tax audit, the completion of the audit is an important milestone—but it is not the final step.
After the Chartered Accountant completes the tax audit and the applicable audit report is furnished, the business still needs to ensure that its Income Tax Return is prepared correctly. The figures reported in the ITR should be consistent with the audited financial statements and applicable information reported through the tax-audit process.
A mismatch between the ITR, tax-audit report, GST returns, TDS records or other tax information can create unnecessary questions during processing or assessment.
This makes the period immediately after the tax audit extremely important.
For FY 2025–26 / AY 2026–27, businesses continue to follow the Income-tax Act, 1961 framework. The corresponding tax-audit provision under the Income Tax Act, 2025 applies to Tax Year 2026–27 onward.
What Happens After a Tax Audit?
Once the tax audit is completed, the business should not immediately file its ITR without reviewing the final numbers.
The post-audit process generally involves:
- Reviewing the final audited financial statements
- Checking the tax-audit report
- Reviewing Form 3CD disclosures
- Calculating taxable income
- Verifying depreciation
- Reconciling tax credits
- Checking brought-forward losses
- Reviewing deductions and disallowances
- Calculating final tax liability
- Adjusting advance tax and TDS/TCS
- Reviewing the ITR before submission
- Verifying the filed return
The exact process depends on the business structure and applicable ITR form.
1. Check the Final Audited Financial Statements
The first step is to make sure the financial statements being used for the ITR are the finalised audited statements.
Review:
- Profit and Loss Account
- Balance Sheet
- Cash-flow statement, where applicable
- Schedules
- Notes to accounts
- Debtors
- Creditors
- Loans
- Fixed assets
- Capital accounts
- Provisions
- Outstanding liabilities
The profit or loss reported in the ITR should be based on the finalised financial information.
Why this matters
If financial statements are changed after the tax-audit report has been prepared, the corresponding tax implications and reporting requirements should be reviewed before filing the ITR.
Businesses should avoid using an earlier draft of their accounts when preparing the final return.
2. Verify Form 3CD Details
For FY 2025–26, where tax audit applies under Section 44AB of the Income-tax Act, 1961, Form 3CD contains various prescribed particulars relating to the taxpayer.
The business should review the final tax-audit report and ensure that important information is correctly reflected in the ITR.
Check items such as:
- Business nature
- Accounting method
- Turnover
- Taxable profit
- Depreciation
- Disallowable expenses
- Loans and deposits
- TDS/TCS compliance
- GST-related information
- Statutory liabilities
- Other prescribed disclosures
A CA should review any significant discrepancy between the tax-audit report and the proposed ITR before filing.
3. Reconcile Turnover With GST Returns
One of the most important post-audit checks is comparing business turnover with GST records.
Businesses should compare their books with relevant GST information, including:
- GSTR-1
- GSTR-3B
- GSTR-9, where applicable
- E-invoice records
- Credit notes
- Debit notes
The turnover appearing in books may not always exactly match GST figures because of timing differences, exempt supplies, non-GST transactions, advances, credit notes or other accounting and GST-treatment differences.
However, every material difference should be understood and properly supported.
Example
Suppose:
Turnover as per books: ₹2.50 crore
Turnover reported through GST: ₹2.45 crore
The ₹5 lakh difference should not simply be ignored.
The business should identify whether it relates to:
- Exempt supplies
- Credit notes
- Non-GST transactions
- Timing differences
- Accounting errors
- GST classification differences
A proper reconciliation creates a clear audit trail.
4. Check TDS and TCS Credits
Before filing the ITR, businesses should verify available tax credits.
Compare:
- Books
- TDS certificates
- Form 26AS
- AIS
- TCS records
- Tax-payment challans
If TDS appearing in the books is different from the amount reflected in Form 26AS or other tax records, the difference should be investigated.
Why TDS reconciliation matters
Incorrectly claiming TDS can result in a mismatch during return processing.
At the same time, failing to claim legitimate TDS credit can increase the taxpayer’s final tax payable.
Therefore, businesses should reconcile tax credits before filing rather than correcting them after the return has already been processed.
5. Verify Advance Tax Payments
Businesses that paid advance tax during the year should verify every challan.
Check:
- Challan number
- Payment date
- Amount
- Assessment year
- PAN
- Major head/minor head, where relevant
The total advance tax reported in the ITR should agree with the available tax records.
September advance tax matters
For taxpayers following the regular advance-tax instalment system, payments are generally made during the year based on estimated tax liability.
Before filing the final ITR, all advance-tax payments should be reconciled with the tax records so that the final tax calculation is accurate.
6. Recalculate Depreciation
Depreciation is another area that should be reviewed carefully after the audit.
Businesses should check:
- Fixed assets purchased during the year
- Date of purchase
- Date put to use
- Asset classification
- Applicable depreciation rate
- Additions
- Disposals
- Written-down value
- Depreciation claimed
The depreciation recorded in the books and depreciation allowed for income-tax purposes can differ.
Therefore, businesses should maintain a proper tax depreciation working rather than simply copying the depreciation figure from the Profit and Loss Account.
7. Check Disallowances Identified During the Audit
The tax audit may identify expenses that require adjustment while calculating taxable income.
These can include applicable disallowances relating to:
- Certain unpaid statutory liabilities
- TDS-related non-compliance
- Cash transactions
- Personal expenses
- Capital expenses
- Certain specified payments
- Other expenses restricted under the Income-tax Act
The business should ensure that all relevant adjustments identified during the audit are correctly incorporated into the tax computation.
8. Verify Outstanding Statutory Liabilities
Businesses should review statutory dues appearing in the Balance Sheet.
These may include:
- GST
- TDS
- PF/ESI, where applicable
- Professional tax
- Other statutory liabilities
The tax treatment of unpaid statutory liabilities depends on the relevant provisions and timing of actual payment.
The figures reported in the financial statements and tax computation should therefore be reconciled.
9. Check Brought-Forward Losses
Businesses that have losses from previous years should verify whether they are eligible for set-off or carry-forward.
Check:
- Previous ITRs
- Loss schedules
- Assessment records
- Unabsorbed depreciation
- Brought-forward business losses
- Capital losses
- Applicable carry-forward periods
Do not assume that the figure in the accounting software is automatically the correct tax figure.
Tax losses should be reconciled with the amounts accepted or reported in earlier returns.
10. Review Deductions and Tax Benefits
Before filing the ITR, review all deductions and tax benefits claimed by the business.
Depending on the business and applicable tax regime, this may involve:
- Depreciation
- Eligible business expenditure
- Donations
- Specific deductions
- Incentives
- Other tax benefits
Every deduction should have appropriate supporting documentation and satisfy the relevant legal conditions.
11. Verify Related-Party Transactions
Businesses should carefully review transactions involving:
- Directors
- Partners
- Promoters
- Relatives
- Group companies
- Related entities
Where applicable, these transactions may require specific reporting or tax treatment.
The amounts appearing in the financial statements, tax-audit report and ITR should be consistent.
12. Check Loans, Deposits and Cash Transactions
Certain transactions involving loans, deposits and cash can have specific reporting and tax implications.
Businesses should review:
- Loans received
- Loans repaid
- Deposits received
- Deposits repaid
- Cash transactions
- Transactions with related parties
- Large financial transactions
Proper documentation should be maintained for significant transactions.
13. Reconcile AIS and Form 26AS
Businesses should not rely exclusively on their accounting records.
The Annual Information Statement (AIS) and Form 26AS can contain information reported by various entities and government systems.
Review information such as:
- TDS/TCS
- Interest
- Securities transactions
- Other reported financial information
- Tax payments
- Refunds
- Demands
If the AIS contains information that appears incorrect or unfamiliar, the taxpayer should investigate it before finalising the return.
14. Check the Correct ITR Form
Using the correct Income Tax Return form is essential.
The applicable ITR depends on factors such as:
- Business structure
- Nature of income
- Turnover
- Residential status
- Business activities
- Capital gains
- Foreign assets/income
- Other applicable conditions
For example, companies, partnership firms, LLPs and individuals carrying on business may have different ITR requirements.
The business should verify the applicable form rather than selecting an ITR based only on previous-year filing.
15. Review the Tax Regime and Applicable Provisions
Businesses should verify the tax regime and provisions applicable to them for the relevant year.
The tax calculation should account for:
- Applicable tax rate
- Surcharge
- Health and education cess
- MAT/AMT, where applicable
- Deductions
- Depreciation
- Tax credits
- Applicable exemptions
For companies and firms, the tax computation may differ significantly from individual taxpayers.
16. Recalculate the Final Tax Liability
After all adjustments, calculate:
Taxable Income → Income Tax → Surcharge → Cess → Interest → Total Liability → Less TDS/TCS → Less Advance Tax → Balance Payable/Refund
This final calculation should be reviewed carefully before filing.
Example
Suppose:
Final tax liability: ₹8,00,000
TDS/TCS: ₹2,00,000
Advance tax: ₹5,00,000
Balance:
₹8,00,000 − ₹2,00,000 − ₹5,00,000 = ₹1,00,000
If applicable interest or other amounts are added, the final self-assessment tax payable will increase accordingly.
17. Check Interest Under the Income-Tax Act
Before filing, businesses should verify whether any interest is payable.
Potential areas include:
- Advance-tax shortfall
- Advance-tax deferment
- Late filing
- Other applicable statutory interest
For FY 2025–26, the relevant provisions under the Income-tax Act, 1961 continue to apply.
For Tax Year 2026–27 onward, corresponding provisions are found under the Income Tax Act, 2025.
18. Verify Self-Assessment Tax
If tax remains payable after adjusting TDS, TCS and advance tax, the business may need to pay self-assessment tax before filing the return.
The taxpayer should verify:
- Tax calculation
- Interest
- Challan amount
- PAN
- Relevant assessment year/tax year
- Payment status
Do not simply estimate the final payment. It should be based on the final tax computation.
19. Review ITR Schedules Carefully
Business ITRs can contain numerous schedules.
Depending on the taxpayer, review may include:
- Business or profession income
- Depreciation
- Balance sheet
- Profit and loss account
- TDS
- TCS
- Advance tax
- Capital gains
- Losses
- Tax computation
- Foreign assets, where applicable
The information should be internally consistent.

Common Mistakes After Tax Audit
Filing the ITR Without Reviewing Form 3CD
The tax-audit report contains important information that should be considered while preparing the ITR.
Copying Previous-Year Figures
Previous-year data can be useful for comparison, but businesses should not automatically copy old figures into the current return.
Ignoring GST Differences
Differences between GST returns and financial statements should be understood and documented.
Not Checking TDS Credits
Failure to reconcile TDS can lead to incorrect tax-credit claims.
Forgetting Advance-Tax Payments
Businesses sometimes overlook one or more challans when preparing the final tax computation.
Incorrect Depreciation
Book depreciation and tax depreciation should not be treated as identical without checking the applicable tax rules.
Ignoring AIS
AIS should be reviewed for reported information that may affect the tax return.
Filing in a Hurry
A tax audit deadline does not mean that the ITR should be prepared without a detailed review.
Tax Audit Completed? Why a Final CA Review Still Matters
A tax audit provides an important level of financial and tax review, but the final ITR still needs to accurately reflect the taxpayer’s complete tax position.
A Chartered Accountant can help with:
- Final tax computation
- Form 3CD review
- ITR preparation
- GST reconciliation
- TDS reconciliation
- AIS review
- Loss verification
- Depreciation calculation
- Tax-credit reconciliation
- Self-assessment tax calculation
- Final ITR review
This additional review can help identify discrepancies before the return is submitted.
Conclusion
Completing a tax audit is an important step, but businesses should not consider their tax compliance finished until the Income Tax Return has been properly reviewed and filed.
After the audit, businesses should compare the audited financial statements with the tax-audit report, GST records, TDS data, AIS, Form 26AS, advance-tax payments and tax computation. Depreciation, losses, deductions, disallowances and statutory liabilities should also be checked carefully.
For FY 2025–26 / AY 2026–27, businesses should ensure that the final ITR accurately reflects the applicable provisions of the Income-tax Act, 1961.
A structured post-audit review can reduce the possibility of reporting errors and help ensure that the final return is consistent with the financial and tax records.
Frequently Asked Questions
1. Can I file my ITR immediately after completing the tax audit?
Yes, but the final audited figures, tax-audit report, Form 3CD, tax computation, TDS, advance tax and other relevant information should be reviewed before filing.
2. What should I check after a tax audit?
You should check the audited financial statements, Form 3CD, turnover, GST reconciliation, TDS, AIS, Form 26AS, depreciation, losses, deductions, disallowances, advance tax and final tax liability.
3. Should turnover in the ITR match GST turnover?
The figures should be properly reconciled. They may differ for legitimate reasons such as exempt supplies, non-GST transactions, credit notes or timing differences, but material differences should be explained and supported.
4. Should Form 3CD and ITR information match?
Relevant information reported in Form 3CD and the ITR should be consistent. Any legitimate difference should be properly understood and reflected according to the applicable tax provisions.
5. Do I need to check Form 26AS after tax audit?
Yes. Form 26AS should be reconciled with TDS/TCS and tax-payment records before the ITR is filed.
6. Why should businesses check AIS before filing ITR?
AIS may contain financial and tax information reported by different sources. Reviewing it can help identify mismatches or information that needs clarification before filing.
7. What if I find an error after the tax audit is completed?
The issue should be discussed with the tax professional handling the audit and ITR. Depending on the nature of the error, the appropriate correction or reporting approach should be determined before filing.
8. What if tax is still payable after adjusting TDS and advance tax?
The business may need to pay the applicable self-assessment tax, including any relevant interest, before filing the ITR.
9. Is tax audit the same as filing an ITR?
No. Tax audit and ITR filing are separate compliance steps. Completing the audit does not automatically mean that the Income Tax Return has been filed.
10. Can a CA help with post-tax-audit ITR filing?
