ITR-4 AY 2026-27 Due Date 31 August 2026: Last-Mile Filing Checklist

By Ravi Sisodia · Reviewed by CA Divyanshu Sengar · Updated 5 October 2026

For eligible non-audit business/profession taxpayers using ITR-4, the AY 2026-27 due date was 31 August 2026. As of 4 October 2026 the focus is no longer last-minute filing - it is belated-return eligibility, late fee/interest, correct tax payment and prompt verification.

Finin2min 2-Minute Summary

• The Income Tax Department's current ITR-4 FAQ states the AY 2026-27 due date was 31 August 2026.
• That date has passed as of this article's 4 October 2026 source check.
• Eligible taxpayers can still evaluate belated-return filing under the applicable law, subject to statutory time limits and consequences.
• Late filing can attract fee under section 234F and interest where applicable; the portal FAQ notes fee up to ₹5,000.
• Do not choose ITR-4 solely for simplicity - verify resident status, income ceiling, presumptive business/profession eligibility and exclusions.

First confirm that ITR-4 was the correct return

The AY 2026-27 FAQ allows specified resident individuals/HUFs/firms (other than LLP) with total income up to ₹50 lakh and presumptive income under sections 44AD/44ADA/44AE, along with permitted salary/pension, up to two house properties, other sources, small agricultural income and specified section 112A LTCG within the stated threshold.

Directors, holders of unlisted equity shares and persons with disqualifying foreign/special-rate/loss conditions can be outside ITR-4.

After 31 August: quantify consequences before submission

Compute total tax, advance tax/TDS/TCS/self-assessment tax, interest and late fee. Reconcile AIS/26AS and bank challans before filing; a late return with missing credit can create a demand that is harder to fix later.

Use the current portal utility/version because validation logic may have changed after the due date.

Verification still matters

Submission is not the final compliance step. Complete e-verification or ITR-V process within the applicable timeline and save the acknowledgement. An unverified return can fail to achieve the intended filing outcome.

If books/audit facts show ITR-4 was never appropriate, use the correct return rather than forcing presumptive disclosure.

Post-deadline case: taxpayer has refund but no tax payable

A taxpayer who expects a refund may assume missing the 31 August due date has no consequence because no self-assessment tax is payable. That is unsafe. Late-filing rules, loss carry-forward restrictions and verification requirements can matter independently of whether the final computation is a refund.

Run the full return computation and eligibility review immediately. Reconcile TDS/TCS credits that create the refund, because a mismatch can turn the expected refund into a portal demand. File using the current utility rather than a locally saved pre-deadline version.

• Do not delay merely because a refund is expected.
• Reconcile the credit creating the refund.
• Check loss/carry-forward consequences of late filing.

Post-deadline checklist

• ITR-4 eligibility rechecked.
• 31 August due date acknowledged as passed.
• AIS/26AS/TDS credits reconciled.
• Tax, interest and late fee computed.
• Current utility/schema used.
• Return filed and verified.
• Acknowledgement and workings archived.
