1. Three Types of Returns: Original, Belated, and Revised
Under ITA 2025, taxpayers have three opportunities to file or correct their income tax return for any Tax Year. Understanding the differences — timing, consequences, and limitations — helps taxpayers avoid penalties and exercise their rights correctly.
2. Original Return: The Ideal
Filing the ITR by the original due date is always the best option:
| Category | Original Due Date (Tax Year 2026-27) |
|---|---|
| Individuals, HUF, firms (non-audit) | 31 July 2027 |
| Tax audit cases | 31 October 2027 |
| Transfer pricing cases | 30 November 2027 |
3. Belated Return: After the Due Date
If you miss the original due date, you can still file a belated return by 31 December 2027 (for Tax Year 2026-27). But there are consequences:
- Late filing fee (Section 434): Rs 5,000 (Rs 1,000 if income below Rs 5 lakh)
- Interest (Section 419): 1% per month on unpaid tax from original due date — adds significantly to cost
- No carry-forward of business/capital losses: Belated return cannot carry forward most losses (only HP loss and unabsorbed depreciation survive)
- Cannot claim certain deductions: Some time-sensitive deductions may not be available in belated return
- Still better than not filing — non-filing can lead to best-judgment assessment and prosecution
4. Revised Return: Correcting Errors
If you discover an error or omission in an already-filed return (original or belated), file a revised return under Section 275 of ITA 2025:
- Can be filed up to 31 December of the relevant assessment year
- Deadline: 31 December 2027 for Tax Year 2026-27
- Can be filed any number of times within the deadline — each revision supersedes the previous one
- Can add income, claim refunds, correct deductions, fix wrong ITR form errors
- No penalty for filing a revised return — it is specifically permitted
5. When to File a Revised Return
Common situations requiring revised return:
- Missed reporting interest income from a bank (AIS showed it after original filing)
- Forgot to include gains from a mutual fund switch
- Entered wrong PAN of a deductee in TDS schedule
- Claimed wrong deduction amount
- Selected wrong ITR form (minor error — requires revised return with correct form)
- Forgot to claim a legitimate deduction in the original return
6. Updated Return (ITR-U): Section 285A
If both original due date and revision deadline (31 December) have passed, and you want to add income not declared or file a return not filed, use ITR-U (Updated Return) under Section 285A:
- Available for 2 years from end of relevant assessment year
- Additional tax: 25% of (tax + interest) if filed within 1 year from AY end; 50% if filed in 2nd year
- CANNOT be used to claim refund, reduce income, or increase losses
- One-time per Tax Year — cannot revise after filing ITR-U
7. Comparison Table
| Feature | Original | Belated | Revised | ITR-U |
|---|---|---|---|---|
| Deadline (TY 2026-27) | 31 July 2027 | 31 Dec 2027 | 31 Dec 2027 | 31 March 2030 |
| Late filing fee | Nil | Rs 1K-5K | Nil | 25%/50% additional tax |
| Loss carry-forward | Yes (all) | Limited | Depends on original | No (cannot claim losses) |
| Claim refund | Yes | Yes | Yes | No |
| Add income | N/A | Yes | Yes | Yes |
