ITR-6 Filing Guide for AY 2026-27:
Beyond Compliance, Towards Confidence
For: Directors • CFOs • Finance Heads • Company Secretaries • Tax Professionals
Every Company Has Two Financial Stories
One is prepared by your finance team. The other is created by the Income Tax Department.
Your books record transactions. Government systems compile data from GST returns, TDS statements, AIS, MCA filings, banks, and previous tax returns. Your Income Tax Return (ITR-6) is no longer the Department's primary source of information - it is the document used to verify whether all these data points tell the same story.
That is why companies with accurate books still receive tax notices. Modern corporate tax compliance is no longer about calculating tax correctly. It is about ensuring data consistency across every statutory reporting platform.
This guide explains what every company should know before filing ITR-6 for Assessment Year 2026-27.
Who Should File ITR-6?
ITR-6 is applicable to all companies registered under the Companies Act except those claiming exemption under Section 11. Generally, ITR-6 applies to:
Important Due Dates (AY 2026-27)
| Compliance | Due Date |
|---|---|
| Tax Audit Report | 30 September 2026 |
| ITR-6 (Audit Cases) | 31 October 2026 |
| Transfer Pricing Cases | 30 November 2026 |
| Belated Return | 31 December 2026 |
| Revised Return | 31 March 2027 |
What's New in ITR-6 for AY 2026-27?
While the structure of ITR-6 remains familiar, several disclosures deserve greater attention this year.
Enhanced Contact Details
Companies are expected to provide additional communication details, ensuring important notices and departmental communications reach the correct authorised persons.
Expanded Capital Gains Reporting
Schedule CG now requires more detailed reporting for:
- Share buybacks
- Immovable property transfers
- Buyer PAN/Aadhaar
- Ownership percentages
Section 43B(h) Remains Critical
Delayed payments to Micro and Small Enterprises continue to attract disallowance under Section 43B(h). Finance teams should review vendor ageing reports before finalising taxable income.
Schedule AL Reporting
Companies crossing the prescribed threshold must ensure complete disclosure of specified assets and liabilities.
The Five Reconciliations Every Company Must Complete
The quality of an ITR-6 depends on reconciliation - not data entry. Before filing, every company should complete these five checks:
Books vs Financial Statements
Ensure audited financial statements agree with books of account and tax computation.
GST vs Revenue
Revenue reported in ITR should reconcile with GSTR-1, GSTR-3B, and annual GST returns. Differences should be documented with clear explanations.
AIS & Form 26AS
Interest income, dividends, securities transactions, TDS credits, and other information appearing in AIS should be reconciled before filing.
MSME Payments
Review all outstanding creditors covered under the MSMED Act. Delayed payments may require tax adjustments under Section 43B(h).
MAT Credit & Losses
Verify brought-forward MAT credit and business losses with previous year's returns before claiming them.
Why Companies Receive Income Tax Notices
Many directors assume notices arise because tax has not been paid. That is rarely the real reason. Most notices today originate from data mismatches.
GST Turnover Mismatch
Revenue in GST returns differs from revenue reported in ITR.
AIS Mismatch
Dividend income, interest, or capital gains appear in AIS but are omitted from the return.
Wrong Depreciation
Depreciation claimed under the Income-tax Act differs from financial statements without proper reconciliation.
Incorrect MAT Credit
MAT credit claimed does not match departmental records.
MSME Disallowance
Section 43B(h) adjustments are ignored despite delayed payments.
A Practical Example
ABC Private Limited
₹15 Crore
Completed
Fully Paid
15 November 2026
Although the company paid all taxes on time, the return was filed after the due date. Consequences included:
- Late filing fee under Section 234F
- Interest implications
- Restriction on carry-forward of certain losses
- Increased compliance risk during processing
Corporate Filing Workflow
A robust filing process should follow this sequence:
- 1 Finalise books of account
- 2 Complete GST reconciliation
- 3 Reconcile AIS and Form 26AS
- 4 Review MSME ageing under Section 43B(h)
- 5 Complete tax audit
- 6 Compute taxable income
- 7 Prepare ITR-6
- 8 Perform internal review
- 9 Verify through Digital Signature Certificate (DSC)
- 10 Preserve acknowledgements and supporting documentation
Before You Click “Submit”
Ask your finance team these questions before filing:
- Has AIS been fully reconciled?
- Does GST turnover match financial statements?
- Have all TDS credits been verified?
- Has Section 43B(h) been reviewed?
- Are capital gains correctly reported?
- Is MAT credit reconciled?
- Is the authorised signatory's DSC active?
- Have all schedules been reviewed against the tax audit report?
Frequently Asked Questions
Q1. Can a Private Limited Company file ITR-3?
No. Companies generally file ITR-6 unless they are required to file ITR-7.
Q2. Is DSC mandatory?
Yes. Most companies are required to verify their returns using a valid Digital Signature Certificate.
Q3. Can an ITR-6 be revised?
Yes. A revised return may be filed within the prescribed statutory time limits, subject to applicable conditions.
Q4. Is AIS reconciliation mandatory?
While there is no separate legal requirement to reconcile AIS, doing so significantly reduces the likelihood of processing adjustments and notices.
Q5. Does every company require a tax audit?
No. Tax audit applicability depends on the provisions of the Income-tax Act. However, statutory audit requirements under the Companies Act continue to apply separately.
Final Thoughts: Corporate tax compliance is no longer about filing a return before the deadline. It is about ensuring that your books, GST returns, AIS, TDS records, financial statements, and tax computation present one consistent version of your business. An ITR-6 prepared with proper reconciliation not only reduces the likelihood of notices but also strengthens governance, improves compliance confidence, and saves management time during assessments. As tax administration becomes increasingly data-driven, companies that invest in accurate reporting today will spend less time responding to queries tomorrow.
