Penalty for Missing ITR Filing Deadlines (AY 2027–28)
Under Section 234F of the Income Tax Act, taxpayers who file returns after the due date must pay a late filing fee.
| Total Income | Filing Date | Penalty |
| Up to ₹5 lakh | After due date | ₹1,000 |
| Above ₹5 lakh | Before 31 December 2026 | ₹5,000 |
| Above ₹5 lakh | After 31 December 2026 | Higher consequences may apply |
The penalty amount must be paid before submitting the belated return.
Penalty Under Section 234F – The Late Filing Fee
Section 234F of the Income Tax Act, 1961 (effective from FY 2017–18) imposes a mandatory fee for filing your ITR after the due date. This is not a discretionary penalty – the Income Tax Department automatically levies it when you file a belated return.
- Income ≤ ₹5 lakh: Maximum late fee is ₹1,000
- Income > ₹5 lakh: Late fee is ₹5,000 (reduced from ₹10,000 since FY 2021)
- Below basic exemption limit: Nil – no late fee if total income is below the basic exemption limit
| Filing Timeline | Fee (Income ≤ ₹5 Lakh) | Fee (Income > ₹5 Lakh) |
| Filed on or before 31 July 2026 (due date) | No Penalty | No Penalty |
| Filed after 31 July 2026 but on or before 31 December 2026 | ₹1,000 | ₹5,000 |
| Filed after 31 December 2026 (if extended window applies) | ₹1,000 | ₹10,000* |
| Total income below basic exemption limit | No Penalty | Not Applicable |
*The ₹10,000 cap applies as per the original statute; the CBDT may amend this. Always check the current notification.
Penalty for Late Filing – Individuals
For individual taxpayers – salaried employees, self-employed professionals, freelancers, and investors – late filing primarily attracts the Section 234F fee, plus interest charges if taxes remain unpaid.
Section 234A – Interest on Unpaid Tax
If you have any outstanding tax liability at the time of filing a belated return, The Income Tax Department charges interest at 1% per month (or part thereof) on the unpaid tax amount, calculated from the original due date until the actual date of payment or filing.
Example: If you owe ₹50,000 in taxes and file your return 3 months late, you will pay ₹1,500 in interest under Section 234A (₹50,000 × 1% × 3 months), in addition to the ₹5,000 late fee under Section 234F.
Section 234B – Advance Tax Default
If your total tax liability exceeds ₹10,000 in a financial year, you must pay advance tax. Failure to pay at least 90% of the total tax as advance tax attracts interest at 1% per month from 1 April of the assessment year until the tax is fully paid.
Section 234C – Delay in Advance Tax Instalments
Taxpayers must pay advance tax in specified installments during the year. If you miss or short-pay any instalment, The Income Tax Department charges interest at 1% per month on the shortfall for that instalment period.
| Advance Tax Instalment | Due Date | Minimum % of Total Tax Due |
| 1st Instalment | 15 June | 15% |
| 2nd Instalment | 15 September | 45% |
| 3rd Instalment | 15 December | 75% |
| 4th Instalment | 15 March | 100% |
Penalty for Late Filing – Companies & Firms
Private limited companies and partnership firms face stricter penalties compared to individual taxpayers.
For Private Limited Companies
| Compliance Issue | Section | Penalty Amount |
| Late filing of ITR | 234F | ₹10,000 flat penalty |
| Failure to file return | 271F | ₹5,000 per day until default continues |
| Carrying on business without filing | 271BA | ₹10,000 flat penalty |
| Inaccurate details / concealment of income | 271AAB | 30%–60% of tax sought to be evaded |

| Late filing under Section 234F | ₹5,000 |
| Interest under Section 234A (on unpaid tax) | 1% per month on unpaid tax |
| Defective return (not corrected in time) | ₹5,000 |
| Non-compliance with tax audit requirement | 0.5% of turnover or ₹1,50,000, whichever is less |
Penalty for Late Filing – Trusts

| Religious trusts | ₹5,000 |
| Private trusts (taxed as AOP) – based on income level | ₹1,000 or ₹5,000 |
| Interest under Section 234A (unpaid tax) | 1% per month on unpaid tax |
Consequences of Late Filing of ITR
Missing the ITR filing deadline goes beyond just a monetary penalty:
- Late Fee under Section 234F: Up to ₹5,000 (or ₹1,000 for income up to ₹5 lakh).
- Interest under Section 234A: 1% per month on any outstanding tax liability until the return is filed.
- No Carry Forward of Losses: Business losses and capital losses (other than house property losses) cannot be carried forward to future years.
- Delay in Tax Refunds: The Income Tax Department processes refunds after you file your return. Filing late delays your refund.
- Cannot Opt for Old Tax Regime: Filing a belated return may result in losing the option to choose the old tax regime with deductions for that year.
- Prosecution Risk for Willful Default: Deliberately failing to file a return despite a legal obligation can attract prosecution under Section 276CC.
- Restricted Loan Processing: Banks typically require the last 2–3 years’ ITRs for processing home loans, personal loans, and business loans.
- Difficulty Obtaining Visa: Many embassies ask for ITR copies as proof of income during visa processing.
File an Updated Return Under Section 139(8A)
Taxpayers who missed filing or reported incorrect income may file an Updated Return (ITR-U). You may have to pay additional taxes.
Benefits of filing ITR-U: avoid future notices, correct previously omitted income, maintain tax compliance, and reduce legal complications.
Benefits of Timely Filing of ITR
- Carry Forward of Losses: Capital gains losses and business losses can be set off against future income.
- Faster Refund Processing: The Income Tax Department prioritises returns filed before the due date for processing.
- Easier Loan Approvals: Timely ITRs act as valid income proof for home loans, car loans, and business credit.
- Revised Return Option: Filing on time gives you the opportunity to file a revised return (up to 31 March 2027) if you discover errors.
- Choice of Tax Regime: Timely filers can choose between the old and new tax regimes to minimise tax liability.
- Builds Financial Credibility: Consistent ITR filing history strengthens your financial profile.
- Peace of Mind: Avoids notices, scrutiny, and follow-up compliance obligations.
Belated vs Revised vs Updated Return (ITR-U)
| Feature/Criteria | Belated Return (Sec 139(4)) | Revised Return (Sec 139(5)) | Updated Return ITR-U (Sec 139(8A)) |
| Who Files | Those who missed the original due date | Those who filed on time but made errors | Those wanting to disclose missed/additional income |
| Deadline | 31 December 2026 | 31 March 2027 | Within 2 years of end of Assessment Year |
| Late Fee / Extra Tax | ₹1,000 or ₹5,000 under Sec 234F | None (if you filed the original return on time) | 25%–50% additional tax plus interest |
| Carry Forward Losses | Not allowed (except HP loss) | Allowed (as per original return) | Cannot be used to reduce income |
ITR-U Key Rule: You can file an Updated Return even if you have not filed the original return. Taxpayers cannot use ITR-U to claim a refund or reduce their tax liability – it is only for disclosing additional income.
ITR Not Filed for Previous Financial Years?
For financial years still within the two-year window from the end of the Assessment Year, you can file an Updated Return (ITR-U) under Section 139(8A). For years older than that window, taxpayers can no longer file voluntarily. However, the Income Tax Department may still issue a notice under Section 148 for income escaping assessment. In such cases, consult a Chartered Accountant immediately.
If you have not filed returns for previous years: the department may issue notices, The Income Tax Department continues to levy interest and penalties, refund claims may become invalid, Late filing may affect loan and visa applications, and severe cases can lead to prosecution proceedings. It is advisable to regularise pending filings as early as possible.

Frequently Asked Questions
What is the last date to file ITR for FY 2025–26 (AY 2026–27)?
For individuals, salaried employees, and HUFs not required to get accounts audited, the due date is 31 July 2026. The belated return deadline is 31 December 2026.
Is the Section 234F penalty mandatory or can it be waived?
The Income Tax Department automatically applies the late fee under Section 234F when you file a belated return. The Income Tax Department does not provide any provision to waive it. However, no late fee applies if your total income is below the basic exemption limit.
Can I still file my ITR after 31 December 2026?
Generally, no. The belated return window closes on 31 December 2026. After that, you may only file an Updated Return (ITR-U) under Section 139(8A) with an additional tax payment, or respond to a tax department notice.
Can I carry forward my business losses if I file late?
No. Filing a belated return disallows the carry forward of business losses, capital gains losses (other than house property losses), and speculative losses.
What happens if I make an error in my return after filing on time?
You can file a Revised Return under Section 139(5) up to 31 March 2027 for AY 2026–27. There is no additional penalty for filing a revised return, as long as you filed the original return before the due date.
Does the late fee apply if I have zero tax liability?
Yes, the late fee under Section 234F applies even if there is no tax due – unless your total income is below the basic exemption limit. Section 234A interest, however, only applies if there is actual unpaid tax.
I have not filed my ITR for the last 3 years. What should I do?
For the most recent years still within the ITR-U window, file Updated Returns immediately and pay the applicable additional tax. For older years, consult a Chartered Accountant to assess your risk exposure before receiving a notice.
