## Key Dates & Deadlines to Keep in Mind

| **ITR Filing Due Date** | Typically 31 July; certain forms/extensions may vary | Neglecting deadlines leads to fees under Section 234F. ([incometax.gov.in](https://www.incometax.gov.in/iec/foportal/latest-news?link=6&mobile-app=1&page=%2C1&utm_source=openai)) |
| **Form 121 Declarations** | Declaration in Part A must be submitted by payee; payer issues UIN; quarterly Part B required | Use 26-character UIN and file Part B quarterly. ([incometax.gov.in](https://www.incometax.gov.in/iec/foportal/sites/default/files/2026-04/Notification-No-01-CPC-TDS-2026.pdf?utm_source=openai)) |

## Practical Examples & Common Mistakes
- **Individual with side income and foreign assets**: View foreign-asset info through the Annual Information Statement (AIS), ensure disclosure. Discrepancies may trigger notices. ([incometax.gov.in](https://www.incometax.gov.in/iec/foportal/latest-news?year=2026&utm_source=openai))
- **Business-eligible for IFSC Unit status**: If you forget to submit Form 1-28 or do not effectively trigger deduction election, TDS exemptions won’t apply even if income is eligible.
- **Mismatch of IFSC bank codes or misfilled schedules**: Technical errors rejected at validation—attend to bank details and linking of schedules. ([incometax.gov.in](https://www.incometax.gov.in/iec/foportal/sites/default/files/2026-05/CBDT_e-Filing_ITR%204_Validation%20Rules_AY%202026-27.pdf?utm_source=openai))
## Actionable Checklist
- Confirm your tax domicile, status, and whether income falls under new Act threshold.
- Update e-filing login, review latest forms, and use new utilities.
- For entities in IFSC, ensure election and declarations are in place early.
- Maintain accurate records and submissions — declarations, lease agreements, invoices.
- Use AIS to review reported foreign assets; reconcile to avoid mismatches and potential scrutiny.
## Conclusion
India’s tax law modernization under the **Income-tax Act, 2025** offers clarity, newer tools, and potential reliefs—especially for IFSC Units. However, it also demands updated discourses on compliance: updated forms, timelines, declarations, and transparency. Advance planning, accurate data capture, and prompt action will buffer taxpayers against avoidable penalties.
