What changes and what does not
The new Act modernises and reorganises income-tax law from April 2026. Core compliance remains familiar: compute income, claim eligible deductions, pay taxes, file returns and respond to notices.
Key structural changes
- Simpler language and reorganised clauses.
- New references for old section numbers.
- Tax year terminology needs software and payroll updates.
- Digital assets and platform economy provisions are clearer.
- Old provisions remain relevant for past assessments and appeals.
What taxpayers must do
- File FY 2025-26 using applicable current-year forms and instructions.
- From FY 2026-27, verify new Act references in payroll and ITR tools.
- Keep old investment certificates; deduction treatment is mapped through law/software.
- Ask CA to map old-to-new references in notices.
TDS and declaration changes to review
- Section 194T partner remuneration TDS.
- Revised thresholds/rates where notified.
- Form 121 transition if applicable.
- Payroll and vendor master updates.
