Why section numbers changed
The new Act reorganises provisions for readability. Old sections from the 1961 Act are mapped into new clauses, but old-year filings and notices may continue to use old references.
Common mappings to track
| Old reference | Topic | Action |
|---|---|---|
| 80C | Savings and investments | Map through software/current form instructions. |
| 24(b) | Home loan interest | Check old/new regime availability. |
| 139 | Return filing | Use new Act filing clause for FY 2026-27 onward. |
| 194J | Professional fees TDS | Update vendor/payroll systems. |
| 234A/B/C | Interest | Map in notices and computations. |
What documents may still reference old law
- PPF/LIC/ULIP certificates.
- Form 16 and older salary declarations.
- Bank TDS certificates.
- Loan interest certificates.
- Notices for earlier years.
