Due dates are frequently extended by notification or circular. Verify on the official portal before relying on them. Section references are to the Income-tax Act, 1961 (up to FY 2025-26); the Income-tax Act, 2025 re-numbers provisions from tax year 2026-27.

Penalty / consequence of delay
Missed deduction (no statutory penalty).
How to comply
- Compare old vs new regime
- Invest or pay premiums by 31 March

Tips to stay compliant
- Add the due date to your calendar a week early and keep documents ready.
- Reconcile books with portal data before filing; fix differences first.
- Keep acknowledgements, challans and working papers for at least the statutory retention period.
- Watch for CBDT / CBIC / MCA notifications: extensions and relaxations are common, but never assume one.
