Overview of Income Tax Rules, Deadlines, Penalties, and New Law Transition for FY 2025-26
Filing an Income Tax Return (ITR) is something every taxpayer needs to do, and it’s important to do it on time. If you miss the deadline, you might have to pay a penalty and interest, and in some cases, it can even create legal trouble.
For the financial year 2025-26 (the assessment year will be 2026-27), the government has set different deadlines for different types of taxpayers. This arrangement has been made so that the filing process remains easy and systematic.
Main deadlines for ITR filing
| Category of Taxpayer | ITR Forms | Due Date |
| Salaried Individuals / Pensioners | ITR-1, ITR-2 | July 31st, 2026 |
| Business / Professionals (No Audit) | ITR-3, ITR-4 | August 31st, 2026 |
| Business / Professionals (Audit Required) | ITR-3, ITR-4 | October 31st, 2026 |
| Belated Return (Late Filing) | All Forms | December 31st, 2026 |
- The deadline for salaried employees, pensioners and investors has been kept till July 2026.
- For businesses and professionals (who are not required to be audited), the deadline extends to August 2026.
- For cases where an audit is necessary, filing has to be done by October 2026.

Revised and updated return timeline

| Updated Return | Report missed income or updates | Valid up to 31 March 2031, within 4 years from the end of the Assessment Year. |
If a person later wants to correct a mistake in his filed ITR, he can file a Revised Return. Through this, the mistakes made earlier can be corrected. Apart from this, the facility of Updated Return (ITR-U) is also provided, in which missing income or updated information can be reported later, but there is a fixed time limit for this also.
