Last Date for ITR Filing: Due Dates, Extensions & Late Filing Penalties (AY 2026-27)

Last Updated on July 6, 2026

Depending on your status as an individual or a business, the last date to submit your ITR (Income Tax Return) may vary based on when the income was received. If you do not submit by that date, there may be penalties. This write-up provides information about which taxpayers must file their returns by which deadline, what happens if they do not file, how you can still file your return and have it accepted as a timely filed return, and includes explanations of all these topics relative to individuals (employed), small business owners, self-employed professionals or other types of taxpayers.

What is ITR Filing?

The process of ITR filing consists of the submission of your income details, tax deductions, taxes paid, and all other necessary information about you to the I.T Department. The return is filed for the assessment year in question, using the form prescribed for each taxpayer depending on the source and nature of their income. The tax department’s website provides details about filing dates, as well as details about each form.

ITR filings serve as proof of income for many taxpayers, and for others, they are just a legal requirement. If an adequate ITR filing is done, it can be beneficial to taxpayers for borrowing money, applying for visas and getting refunds, or verification of tax for future years.

Why is the Last Date for ITR Filing Important?

It is very important to file your ITR on or before the due date, as there are additional costs to taxpayers for late filing; these include charges for late payments, interest, and filing a belated return. In addition, if you do have losses for the tax year, these losses will be used in future tax years, and if a taxpayer files late, he or she is likely to create confusion for the I.T Department regarding the taxpayer’s compliance for that year. The I.T Department FAQ will assist taxpayers in determining their rights for belated, revised, and amended returns depending on what is occurring at the time of filing their returns.

In addition to being costly, late filing of the ITR. will also create confusion regarding financial planning, delay taxpayers’ refunds, and leave taxpayers unsure whether they have proof of income for other legal or financial purposes.

Who Needs to File an ITR?

Individuals, Hindu Undivided Families, Firms, companies, Limited Liability Partnerships or other types of taxpayers may be required to file an income tax return based on the type of income, allowable deductions and whether or not they are subject to the law regarding filing income tax returns in the respective assessment year. Generally, tax return filers are salaried taxpayers, business and profession owners, and those with capital gains or foreign investment earnings. The obligation for these taxpayers to file a return is based on the applicable statutory provisions in the assessment year identified.

In addition, taxpayers who have tax deducted at source (TDS) must file a return to report their total income in order to receive a refund of any overpayment due to TDS. The majority of taxpayers are required to file an income tax return, regardless of how much tax they may owe.

Who is Mandatorily Required to File an ITR?

Under the Income Tax Act, filing is mandatory regardless of income level if any of the following apply:

• Deposited more than ₹1 crore in one or more current bank accounts in the year
• Incurred foreign travel expenditure exceeding ₹2 lakh
• Paid electricity bills exceeding ₹1 lakh during the year
• Has foreign assets or income
• Claimed TDS/TCS refund
• Business turnover exceeds prescribed limits

For individuals, the basic exemption is ₹2.5 lakh (old regime) or ₹3 lakh (new regime); income below this is generally not required to file unless one of the triggers above applies. However, filing, even when not mandatory, builds a financial record that’s useful for loans, visas, and future compliance.

ITR Filing Eligibility and Filing Categories

The due date for filing a return of income is based upon the type of return and whether or not the taxpayer’s taxes have been subject to audit.

Generally, taxpayers can fall into the following categories: (1) salaried individuals, (2) non-audit business/profession, (3) audit, and (4) transfer pricing. Each category will have a separate due date for filing, so when looking at the last date for filing income tax returns, it is important to consider the taxpayer classification involved.

New vs Old Tax Regime – Which to Choose and When

From FY 2023-24, the new tax regime is the default. If you want to opt for the old regime (with deductions like 80C, 80D, HRA), you must actively choose it, and the deadline for that choice matters:

• Salaried individuals can switch between regimes every year — but must declare their choice to the employer before the year ends and confirm it in the ITR
• Business/professional taxpayers can opt out of the new regime only once — after opting out, they cannot switch back except in very limited circumstances
• The option to choose the old regime for business taxpayers is available only if you file on or before the due date — a belated return locks you into the new regime by default

This makes filing on time not just a penalty issue; it’s a tax planning issue for lakhs of business owners.

Documents Required for ITR Filing

• PAN
• Aadhaar, if required.
• Salaried people need Form 16 to file their returns.
• Form 26AS and AIS or TIS.
• Bank account number.
• Proof of deduction & proof of investment.
• TDS or TCS certificate.
• If it is for business/professional activity, then Business/Professional Accounts.
• If your case is subject to audit, you are required to provide an audit report.

The final list of required documents will depend on the type of return that you will be filing and your income type. Taxpayers who receive business income; capital gains; foreign based income; or incur losses must have supporting documentation ready prior to filing to avoid problems from erroneous filings.

Step-by-Step Process to File ITR

1. Determine the appropriate assessment year and corresponding return form.
2. Gather all necessary documentation for income, deductions, and tax credits.
3. Reconcile your TDS, payment of advance tax and self-assessment tax against the documents you gathered.
4. Accurately fill in the return and review all data entered as part of your return.
5. Submit your return through the e-filing portal.
6. Complete the necessary verification for the filing of the return by the prescribed means.
7. Retain a copy of both your acknowledgement and the return itself.

You can confirm deadlines, filing status, changes to returns, etc., by reviewing the tax portal and calendar. It is best to file as early as possible to limit any last-minute issues with portals or paperwork.

Advance Tax

If your total tax liability exceeds ₹10,000 for the year, you must pay tax in advance during the year itself, not just at the time of filing.

Installment	Due Date	Amount to Pay
1st	June 15	15% of estimated tax
2nd	September 15	45% cumulative
3rd	December 15	75% cumulative
4th	March 15	100%

Missing these instalments triggers Section 234C interest even if you file your ITR on time. Salaried individuals with only salary income and TDS deducted properly are generally exempt. TDS covers their advance tax obligation automatically.

ITR Filing Fees, Late Fee, and Interest

If your tax return is filed late, certain fees may apply based on your filing status. According to the Income Tax FAQ published by the tax authority, if you file a belated return for AY 2026-27 and the total income is ₹5,00,000 or less, the fee assessed will be ₹1,000. If the total income exceeds ₹5,00,000, the fee associated with your belated return will be ₹5,000.

Additionally, if you have an outstanding tax liability on the date of your due tax return filing, you may also be subject to interest. Therefore, it is possible that the cost associated with missing your due date will exceed the cost of filing your tax return on time, even though you might later be able to file a tax return after the due date.

Interest for Late Filing and Non-Payment – Actual Sections and Rates

Beyond the late filing fee, three interest provisions apply:

• Section 234A – Interest for late filing at 1% per month on unpaid tax from the due date until the actual filing date. Applies only if tax remains unpaid. If the full tax is paid via TDS/advance tax, 234A doesn’t bite.
• Section 234B – Interest at 1% per month if the advance tax paid is less than 90% of the total tax liability by March 31. Runs from April 1 until the date of assessment or payment.
• Section 234C – Interest at 1% per month for shortfall in quarterly advance tax instalments during the year itself.

These three can combine – a taxpayer who underpaid advance tax AND filed late can face 234A + 234B + 234C simultaneously, making the effective cost of delay far higher than the ₹5,000 late fee alone.

Belated Return and Revised Return

A belated return can be filed after the original due date but within an appropriate time frame. For AY 2026-27, one can file a belated return by 31 December 2026, or earlier if the assessment is completed before that date.

A revised return is used to correct errors or omissions found on a previously filed return. According to the official FAQ, revised returns for AY 2026-27 will be accepted as per the previous act’s provisions (old act) and should be filed by the due date or before the end of the relevant assessment year, whichever is sooner.

Key Facts About ITR-U You Need to Know

ITR-U can be filed within 2 years from the end of the relevant assessment year. For AY 2026-27 (FY 2025-26), ITR-U can be filed until March 31, 2029.

Additional tax payable: Filing ITR-U isn’t free of cost. An additional tax must be paid:

• 25% of tax + interest if filed within 1 year of the end of AY
• 50% of tax + interest if filed between 1 and 2 years after the end of AY

When ITR-U cannot be filed:

• If the updated return results in a refund or reduces tax liability
• If assessment or reassessment proceedings are pending
• If the taxpayer is under search or survey

ITR-U is not a route to fix any error; it can only be used to declare additional income, not to claim additional deductions or reduce tax.

Compliance Requirements After Filing ITR

After filing, taxpayers should keep the acknowledgement, ITR copy, computation, and supporting documents safely. They should also verify that refunds, if any, are credited to the correct account and that the return status is processed properly on the portal.

If the return is filed late, taxpayers should monitor for any fees, notices, or rectification issues that may arise later. Keeping a complete record makes future responses easier and more accurate.

Penalty and Consequences of Missing the ITR Due Date

If a taxpayer fails to meet their tax obligation, they may experience negative consequences, such as incurring late fees, interest, and being required to file a late return. In some instances, a taxpayer who fails to meet their tax obligation may lose the ability to carry over a certain amount of losses to future tax years under applicable regulations.

There is also a practical noncompliance cost associated with delays in filing an income tax return, as they may result in delays in receiving a tax refund, processing loan application documents and receiving proof of income. The impact of a taxpayer’s noncompliance on their overall tax situation may be greater for business taxpayers, as many business taxpayers rely on compliance with tax regulations to establish credibility in their financial reporting.

Losses Cannot Be Carried Forward If You File Late

This is one of the most financially significant consequences of missing the July 31 deadline that most taxpayers don’t realise:

• Business losses under Section 72 cannot be carried forward if the return is filed late
• Capital losses under Section 74 cannot be carried forward if filed after the due date
• Speculation losses and F&O losses are similarly lost

The only exception: House Property loss can be carried forward even in a belated return.

For traders, investors, and business owners with losses, filing late doesn’t just cost ₹5,000; it can cost the entire tax benefit of those losses in future years.

Common Mistakes to Avoid While Filing ITR

Some of the most common mistakes made by taxpayers include:

1. Using an incorrect assessment year
2. Inaccurately selecting an ITR form
3. Failing to recognise the TDS mismatch with the amount of tax withheld
4. File on last day of the deadline
5. Forgetting to verify their return after submission

It’s a common misconception that individual taxpayers have the same due date for filing a return. The actual due date for any individual taxpayer was determined by the type of return being filed, the individual taxpayer’s audit status, and their individual taxpayer income profile. Therefore, using a single due date for all taxpayers is not appropriate and can create additional errors and/or misunderstandings.

Benefits of Filing ITR on Time

Filing by the required dates has several advantages:

• You will not incur late filing penalties,
• Your interest expense is minimised,
• You will have established a record of your compliance status,
• processing your tax refunds will be easier and quicker,
• obtaining documentation needed for loans/visa applications will be easier,
• You will reduce your chances of making last-minute mistakes when filing your tax return.

Filing on time will help ensure that your business can continue to operate. A clean history of taxes paid will assist you when getting vendor checks, doing business plans, and performing future compliance work.

Example

If an employee earning a salary has no business income and files their tax return using ITR-1 for the financial year 2025-26, they will avoid paying late filing fees if they meet the due date. The refund from this tax return will also be processed more quickly. If the taxpayer misses the due date, they may still have the option of filing their return late as a “belated” return; however, the taxpayer may be subject to late filing fees.

This example illustrates that the due date is more than a date on the calendar; it affects how much it costs to file, the convenience to the taxpayer, and the compliance outcome of their return.
