ITR-3 & ITR-4 Non-Audit Due Date 2026: No Extension Announced, File Your ITR Today

Taxpayers with business or professional income who are not required to get their accounts audited should complete their income tax return filing within the prescribed deadline.

The August 31 deadline is particularly important for proprietors, professionals, freelancers, small business owners and eligible taxpayers opting for presumptive taxation.

ITR-3 & ITR-4 Last Date for AY 2026-27

For FY 2025-26 / AY 2026-27, the applicable deadline for non-audit business and professional taxpayers is:

The Income Tax Department has specifically confirmed that the due date for non-audit business cases was changed from July 31 to August 31, with the change applicable for AY 2026-27.

No Further Extension Announced for ITR-3 & ITR-4

There has been considerable discussion among taxpayers and tax professionals regarding a possible extension of the ITR filing deadline.

However, taxpayers should not assume that an extension will be granted.

As of August 31, 2026, the prescribed deadline remains August 31 for eligible non-audit ITR-3 and ITR-4 taxpayers. Recent reports also confirm that August 31 is the deadline for taxpayers with business or professional income whose accounts do not require tax audit.

Therefore, eligible taxpayers should file their return today rather than wait for a possible extension.

Who Needs to File ITR-3?

ITR-3 is generally applicable to individuals and HUFs having income from business or profession who are not eligible to use ITR-1, ITR-2 or ITR-4.

This may include:

• Proprietors
• Professionals
• Freelancers
• Traders
• Business owners
• Individuals earning income from business and profession
• Partners in certain partnership firms
• Taxpayers having business income along with other sources of income

The Income Tax Department describes ITR-3 as applicable to individuals and HUFs having income under business/profession along with other applicable heads of income, where ITR-1, ITR-2 or ITR-4 is not applicable.

Who Can File ITR-4?

ITR-4, also known as Sugam, is designed for eligible individuals, HUFs and resident firms other than LLPs who meet the prescribed conditions and declare business or professional income under the presumptive taxation provisions.

It can generally apply to eligible taxpayers using presumptive taxation under:

• Section 44AD – eligible business
• Section 44ADA – eligible profession
• Section 44AE – certain businesses involving goods carriages

The Income Tax Department's current guidance confirms the applicability of ITR-4 to eligible resident taxpayers using these presumptive taxation provisions, subject to the prescribed conditions.

What Happens If You Miss the August 31 Deadline?

Missing the original due date does not necessarily mean that you cannot file your income tax return.

A taxpayer may still be able to file a belated return, subject to the applicable provisions, interest and late-filing consequences.

The Income Tax Department states that if an ITR is filed after the due date under the relevant provision, a late filing fee of up to ₹5,000 may apply, along with interest where applicable.

However, filing late can also have other tax consequences depending on the taxpayer's circumstances, including issues relating to certain loss carry-forwards and other statutory benefits.

Therefore, filing within the original deadline is preferable.

Don't Confuse ITR-3/4 Non-Audit With Audit Cases

One important point taxpayers should understand is that the deadline differs depending on whether the taxpayer is subject to tax audit.

Non-Audit Cases

For eligible taxpayers whose accounts are not required to be audited:

Due date: August 31, 2026

This includes applicable ITR-3 and ITR-4 taxpayers.

Tax Audit Cases

Taxpayers whose accounts are subject to tax audit have a different compliance timeline.

The audit report and income tax return are subject to separate prescribed deadlines.

Therefore, taxpayers should determine their audit applicability before deciding which deadline applies to them.

Important Documents to Keep Ready

Before filing ITR-3 or ITR-4, taxpayers should keep the following information and documents ready:

• PAN
• Aadhaar
• Bank account details
• Bank statements
• Sales and purchase information
• Business income details
• Professional receipts
• Expense details
• TDS certificates
• Form 26AS
• AIS and TIS
• Capital gains information, if applicable
• Details of investments and deductions
• Previous year's ITR
• GST-related information, where applicable
• Details of loans and interest, where applicable

Check AIS, TIS and Form 26AS Before Filing

Taxpayers should not simply copy figures from their previous year's return.

Before submitting the ITR, it is advisable to compare the income and tax information with:

AIS – Annual Information Statement

TIS – Taxpayer Information Summary

Form 26AS

This can help identify discrepancies in reported income, TDS, interest income, securities transactions and other information available with the Income Tax Department.

Why You Should File ITR Before the Deadline

Filing on time can help taxpayers:

• Avoid applicable late-filing fees
• Reduce interest exposure where applicable
• Maintain a clean tax compliance record
• Carry forward eligible losses where permitted
• Avoid last-minute technical problems
• Complete tax compliance without unnecessary stress
• Obtain ITR acknowledgement on time

The Income Tax Department has also advised taxpayers to avoid waiting until the last moment because a large number of returns are filed around the deadline.
