ITR-3 and ITR-4 Due Dates and Penalties AY 2026-27

If you earn business or professional income, choosing the correct income tax return form is only the first step. You must also file it within the applicable deadline to avoid Section 234F late filing fees, Section 234A interest, loss carry-forward restrictions and, where applicable, tax audit penalties.

For FY 2025-26 and AY 2026-27, most taxpayers filing ITR-3 or ITR-4 without tax audit must file their income tax return by 31 July 2026. Taxpayers subject to tax audit generally get time until 31 October 2026, while taxpayers with specified international or domestic transactions requiring a transfer pricing report generally have time until 30 November 2026.

ITR-3 and ITR-4 Due Dates for AY 2026-27

The due date depends mainly on whether your accounts are subject to tax audit. The form number alone does not determine the deadline.

Taxpayer category	Applicable return	Statutory due date for AY 2026-27
Individual or Hindu Undivided Family (HUF) not subject to tax audit	ITR-3 or ITR-4	31 July 2026
Individual or HUF whose accounts require tax audit	ITR-3	31 October 2026
Taxpayer required to furnish a transfer pricing report	ITR-3	30 November 2026
Belated or revised return	ITR-3 or ITR-4	31 December 2026

These are the statutory income tax return filing due dates for AY 2026-27, subject to any extension notified by the Central Board of Direct Taxes (CBDT). Taxpayers should check the latest Income Tax Department tax calendar before filing.

ITR-3 due date for AY 2026-27

The ITR-3 due date for AY 2026-27 is generally:

• 31 July 2026 if the individual or HUF is not liable to tax audit.
• 31 October 2026 if the accounts are required to be audited under the Income Tax Act.
• 30 November 2026 where a transfer pricing report under Section 92E is applicable.

ITR-3 is generally used by individuals and HUFs having income from:

• Business or profession that does not qualify for ITR-4.
• Speculative business.
• More than one house property.
• Capital gains along with business or professional income.
• Foreign assets or foreign income.
• Unlisted equity shares.
• Partnership firm remuneration, salary, interest, commission or bonus.
• Business or professional income where the taxpayer does not meet the conditions for ITR-4.

ITR-4 due date for AY 2026-27

The ITR-4 due date for AY 2026-27 is 31 July 2026, provided the taxpayer is not subject to tax audit.

ITR-4, also known as Sugam, is generally available to eligible resident individuals, HUFs and firms other than limited liability partnerships that declare income under the presumptive taxation provisions.

It may apply where income is declared under:

• Section 44AD for eligible businesses.
• Section 44ADA for eligible professions.
• Section 44AE for certain transport businesses.

A taxpayer using ITR-4 must satisfy all eligibility conditions. For example, a taxpayer with certain foreign assets, income from more than one house property, brought-forward losses or specified capital gains may have to use ITR-3 instead.

The Income Tax Department provides guidance on the applicability of ITR forms through its official return filing and forms resources.

ITR-4 Presumptive Taxation Filing Deadline for AY 2026-27

The ITR-4 presumptive taxation filing deadline for AY 2026-27 is 31 July 2026 for eligible taxpayers not liable to tax audit.

Under presumptive taxation, the taxpayer declares income at a prescribed percentage or amount instead of calculating actual business expenses in the usual manner. However, presumptive taxation does not automatically make every taxpayer eligible for ITR-4.

Section 44AD

Section 44AD generally applies to eligible resident individuals, HUFs and partnership firms carrying on eligible businesses. The presumptive income is generally calculated as:

• 8% of eligible turnover or gross receipts, or
• 6% of eligible turnover or gross receipts received through specified banking or electronic modes, subject to the applicable conditions.

The taxpayer may declare a higher income. If the taxpayer declares income below the prescribed presumptive amount and the total income exceeds the basic exemption limit, maintaining books and obtaining a tax audit may become necessary under the applicable provisions.

Section 44ADA

Section 44ADA applies to eligible resident individuals and partnership firms carrying on specified professions. Presumptive income is generally 50% of gross receipts, although the taxpayer can declare a higher amount.

If the taxpayer claims income below the prescribed percentage and meets the conditions that trigger audit, the tax audit provisions may apply. In that case, the taxpayer cannot simply rely on the ordinary ITR-4 deadline.

Section 44AE

Section 44AE applies to taxpayers engaged in the business of operating, leasing or hiring goods carriages, subject to the statutory conditions. Presumptive income is calculated based on the type and capacity of the goods carriage.

When Is ITR-3 Required Instead of ITR-4?

A taxpayer may need to file ITR-3 instead of ITR-4 in several situations. Common examples include:

• The taxpayer has income from speculative business.
• The taxpayer owns foreign assets or earns foreign income.
• The taxpayer has income from more than one house property.
• The taxpayer has certain capital gains that are not supported by the applicable ITR-4 provisions.
• The taxpayer has brought-forward or carry-forward losses requiring detailed reporting.
• The taxpayer is a partner in a firm and receives income that requires ITR-3 reporting.
• The taxpayer is not eligible to declare income under the presumptive taxation provisions.
• The taxpayer has business or professional income but does not satisfy the conditions for ITR-4.

Using ITR-4 merely because it is shorter can lead to an incorrect return. If the form is not applicable, the Income Tax Department may treat the return as defective and require correction.

Tax Audit Due Date for ITR-3 AY 2026-27

The ITR-3 tax audit due date for AY 2026-27 is generally:

• 30 September 2026 for furnishing the tax audit report, where audit is applicable.
• 31 October 2026 for filing the income tax return.

The audit report is generally required one month before the income tax return due date. The taxpayer should not wait until 31 October to start the audit process because the report must be completed and uploaded earlier.

A taxpayer may become liable to tax audit because of:

• Business turnover exceeding the applicable threshold under Section 44AB.
• Professional gross receipts exceeding the applicable threshold.
• Declaring income below the presumptive rate in circumstances covered by the audit provisions.
• Other conditions specified under the Income Tax Act.

The turnover limits and exceptions can depend on cash receipts, cash payments and the method of accounting. Taxpayers should review the current Section 44AB tax audit provisions before deciding whether an audit is required.

Penalty for failure to obtain or furnish a tax audit report

Section 271B may apply when a taxpayer fails to get accounts audited or fails to furnish the audit report as required. The penalty can be:

• 0.5% of total sales, turnover or gross receipts, or
• ₹1,50,000,

whichever is lower, subject to the provisions and reasonable-cause relief available under the law.

This tax audit penalty is separate from the late filing fee under Section 234F and interest under Section 234A.

Belated ITR Filing Penalty Under Section 234F for AY 2026-27

A return filed after the original due date is called a belated return. The belated ITR filing penalty under Section 234F for AY 2026-27 is technically a late filing fee, not a penalty.

The applicable fee is:

Total income	Section 234F fee
Total income up to ₹5,00,000	₹1,000
Total income above ₹5,00,000	₹5,000

The fee is payable when the return is filed after the applicable Section 139(1) due date. The law provides that the fee cannot exceed the amount of tax payable where the total income does not exceed ₹5,00,000.

The Income Tax Department’s Section 234F guidance sets out the late filing fee provisions.

Example of Section 234F fee

Suppose a taxpayer files ITR-4 on 15 August 2026 instead of 31 July 2026:

• If total income is ₹4,80,000, the Section 234F fee can be ₹1,000, subject to the statutory limit.
• If total income is ₹8,00,000, the Section 234F fee can be ₹5,000.

The taxpayer must also pay any applicable interest and unpaid tax before completing the filing process.

ITR-3 and ITR-4 Late Filing Interest Under Section 234A

Section 234A applies when the taxpayer files the return after the due date and has unpaid tax liability. Interest is calculated at 1% for every month or part of a month from the day immediately following the original due date until the date of filing.

Interest is generally calculated on the tax payable after reducing:

• Tax deducted at source (TDS).
• Tax collected at source (TCS).
• Advance tax paid.
• Certain eligible tax credits, as applicable.

The official text of Section 234A should be referred to for the statutory calculation.

Example of Section 234A interest

Assume:

• Tax payable after TDS and advance tax: ₹60,000.
• Original due date: 31 July 2026.
• Actual filing date: 15 August 2026.

Because a part of a month is counted as a full month, interest may be calculated for one month:

₹60,000 x 1% = ₹600

The final amount can change if the taxpayer pays self-assessment tax before filing or if other credits and adjustments apply.

Section 234A interest is not charged merely because the taxpayer filed late. It generally arises when there is tax payable after considering the eligible credits and payments.

Penalty for Late Filing ITR-3 With Business Income

The penalty for late filing ITR-3 with business income usually consists of three separate consequences:

1. Section 234F late filing fee of ₹1,000 or ₹5,000, depending on total income.
2. Section 234A interest at 1% per month or part of a month on the relevant unpaid tax.
3. Possible consequences for late tax audit compliance, including Section 271B exposure where audit was mandatory.

Late filing can also affect the ability to carry forward certain losses. Generally, business losses, speculative business losses and capital losses may not be carried forward if the return is not filed within the original Section 139(1) due date, subject to the specific statutory rules. Losses from house property have separate rules.

Taxpayers should therefore file ITR-3 by the original due date even where the final tax payable is small or zero.

Penalty for Late Filing ITR-4 Under Section 44AD

The penalty for late filing ITR-4 under Section 44AD is generally the same Section 234F late filing fee that applies to other eligible taxpayers:

• ₹1,000 where total income does not exceed ₹5,00,000.
• ₹5,000 where total income exceeds ₹5,00,000.

Section 44AD itself does not impose a separate late filing fee merely because the taxpayer uses presumptive taxation. However, the taxpayer may face:

• Section 234A interest on unpaid tax.
• Interest for delay in advance tax payment under Sections 234B and 234C, where applicable.
• Tax audit consequences if the taxpayer is required to maintain books and obtain an audit.
• Loss carry-forward restrictions where applicable.
• Problems if the taxpayer incorrectly uses ITR-4 despite being required to file ITR-3.

A taxpayer declaring presumptive income should also ensure that the turnover, digital receipts and bank deposits reported in the return are consistent with books, invoices, bank statements, GST returns and Form 26AS or AIS information.

Revised ITR Deadline for AY 2026-27

The revised ITR deadline for AY 2026-27 is generally 31 December 2026.

A revised return can be used to correct an omission or error in an original or belated return. Common reasons for revision include:

• Incorrect bank account details.
• Omission of interest income.
• Incorrect TDS credit.
• Wrong business turnover or presumptive income.
• Failure to report capital gains or other income.
• Incorrect selection of the ITR form.
• Mistakes in deductions or tax regime selection.

The revised return must be filed within the statutory time limit or any later time allowed by a CBDT notification. Filing a revised return does not automatically remove Section 234F fee or interest that arose because the original return was filed late.

A taxpayer should preserve the acknowledgement number of the original return and use it while filing the revised return.

Can a Belated ITR Be Revised?

Yes. A belated ITR can generally be revised if the taxpayer discovers an error after filing it. However, the revised return must be submitted within the permitted deadline.

For AY 2026-27, a taxpayer who files a belated ITR after 31 July 2026 should normally complete the revision by 31 December 2026. The revised return does not reset the original filing date for calculating late filing fee or interest.

New Tax Regime and ITR-3 or ITR-4 Filing

The new tax regime is the default regime for eligible individual and HUF taxpayers. Taxpayers with business or professional income who want to opt out of the new regime and choose the old regime generally need to submit Form 10-IEA within the prescribed time.

For taxpayers with business or professional income, tax regime selection should be reviewed before filing ITR-3 or ITR-4 because:

• The old regime may allow specified deductions and exemptions.
• The new regime has different slab rates and deduction rules.
• Switching regimes can be subject to additional conditions for business or professional income.
• The relevant form and option must be filed within the prescribed return deadline.

The Income Tax Department’s tax regime guidance should be checked for the latest AY 2026-27 instructions and form requirements.

Practical Checklist Before Filing ITR-3 or ITR-4

Complete these steps before submitting your return:

1. Identify the correct ITR form. Do not use ITR-4 if your income or assets require ITR-3.
2. Check the original due date. For most non-audit taxpayers, it is 31 July 2026.
3. Confirm tax audit applicability. If audit applies, check the 30 September 2026 audit report deadline and 31 October 2026 return deadline.
4. Download AIS and Form 26AS. Reconcile TDS, interest, dividends, securities transactions and other reported information.
5. Reconcile business turnover. Match turnover with invoices, bank statements, GST returns and accounting records.
6. Calculate presumptive income correctly. Apply the relevant Section 44AD, 44ADA or 44AE provisions.
7. Calculate self-assessment tax. Include Section 234A, 234B, 234C and Section 234F amounts where applicable.
8. Verify the return. Complete electronic verification through the available Income Tax e-filing methods.
9. Save the acknowledgement. Keep the filed return, computation, challans and verification record.
10. Revise errors by 31 December 2026. A revised return should correct genuine omissions or mistakes before the statutory deadline.
