Penalty for Late Filing of ITR for FY 2025-26 (AY 2026-27)

Missing the ITR filing deadline triggers a cascade of financial consequences beyond just a flat penalty — interest charges, loss of loss carry-forward rights, and complications for future loan applications. Understanding the exact penalty structure, due dates by taxpayer category, and how to file a belated or revised return helps you navigate any missed deadline with minimal damage.

This page covers:

• Key penalties and consequences of late filing
• Due date for filing ITR for AY 2026-27 by taxpayer category
• Due date for revising your return
• Detailed breakdown of penalty sections — 234F, 234A, 234B, 234C, 271H, 270A
• Penalty for private limited companies
• How proper tax planning supports future financial goals

The Central Board of Direct Taxes (CBDT) releases multiple ITR forms (Form 1 to Form 7) for different taxpayer categories each year. As a taxpayer, you must know the last date to file an ITR for the AY 2026-27 based on your category (individual, company, firm, etc.). If you do not file by the due date, you will pay a penalty for late filing, and lose certain benefits like carrying forward losses or faster refund processing.

• Late fee (Sec 234F): Filing after 31 July 2026 but before 31 December 2026 may attract a late fee of up to Rs. 5,000, applicable even if no tax is due
• Reduced penalty: If total income does not exceed Rs. 5 lakh, the late filing fee is reduced to Rs. 1,000
• Interest (Sec 234A): 1% per month or part of a month on any unpaid tax amount until the return is filed and dues are cleared
• No carry forward of losses: Filing late means you cannot carry forward certain losses, such as business or capital losses, to future years
• Belated return deadline: You can still file a belated return, but only up to 31 December 2026

Planning your taxes properly helps avoid penalties and manage finances better — when you organise your tax affairs, you can also plan for major life goals like buying a home. Check eligibility for a home loan from Bajaj Finserv to see how proper financial planning can help you achieve your dream home.

If you realise an error or missed details in your ITR, you can correct it by submitting a revised return on or before 31st December of the relevant assessment year. This gives taxpayers approximately nine months after the end of the financial year to fix mistakes. Filing well before the deadline gives you more time and flexibility to review and revise if needed.

• Allows you to rectify genuine errors or omissions before the assessment process.
• Minimises the risk of receiving tax-related notices in the future.
• Helps ensure that you receive the correct amount of tax refund.
• Supports compliance with the requirements of the Income Tax Department.
• Maintains accurate financial records, which can be helpful for future loan or credit applications.

1. What is the section 234F penalty for late filing?

The ITR late filing fee under Section 234F applies if you file your ITR after the due date:

• Total income more than Rs. 5 lakh: Rs. 5,000
• Total income less than Rs. 5 lakh: Rs. 1,000
• No late fee applies if total income is below the basic exemption limit.

The penalty for late filing of income tax return applies to belated returns filed after the due date (31 July 2026) but before 31 December 2026.
 

2. What is the interest under Section 234A for late payment of tax?

Section 234A applies if you have unpaid taxes and file late:

• Interest charged at 1% per month (or part of a month) on the unpaid tax amount
• Calculated from the due date until the actual date of filing
• Also applies if you changed jobs and failed to submit Form 16
   

3. When does Section 234B interest apply for non-payment of advance tax?

Section 234B applies if your tax liability exceeds Rs. 10,000 in a financial year and you do not pay sufficient advance tax:

• Interest charged at 1% per month
• Applies if you don't pay any advance tax, or pay less than 90% of total tax due
• Calculated from the end of the financial year (March 31) to the date the balance is paid
   

4. What is the interest under Section 234C for delay in advance tax instalments?

Section 234C applies when you fail to pay advance tax instalments on time:

• Interest charged at 1% per month
• Calculated on the difference between actual tax paid and the amount that should have been paid in each instalment
• Advance tax must be paid in instalments on specific dates
   

5. What is the Section 271H penalty for late filing of TDS/TCS returns?

Section 271H applies to those responsible for deducting or collecting tax at source:

• Penalty ranges from Rs. 10,000 to Rs. 1,00,000
• This penalty is separate from the late fee under Section 234E
• Section 234E late fee is Rs. 200 per day until the TDS/TCS return is filed

Updated Return (ITR-U) under Section 139(8A): If you miss both the belated return deadline (31 December 2026) and the revised return deadline (31 March 2027), you may file an ITR-U within 24 months from the end of the relevant assessment year, subject to payment of additional tax.

6. What is the Section 270A penalty for underreporting or misreporting income?

Section 270A applies when you underreport or misreport income:

• Penalty for underreporting is 50% of the tax payable on the underreported amount
• The penalty can apply when you fail to file an ITR or underreport income

Private companies face stricter penalties:

Companies must also pay interest on any tax due at 1% per month, making timely compliance particularly important for business entities.

31 December 2026 is the last date to file a belated ITR for AY 2026-27. Under Section 139(4), a belated return can be filed by this date or before completion of assessment, whichever is earlier. A late-filing fee under Section 234F may apply—Rs. 1,000 if total income does not exceed Rs. 5 lakh and Rs. 5,000 otherwise.

After 31 December 2026, eligible taxpayers may use an ITR-U (Updated Return) under Section 139(8A), subject to applicable conditions, additional tax and statutory time limits.

Missing even the belated deadline means you generally cannot file a regular belated return and may need to explore ITR-U or condonation of delay, where applicable.
