Old vs new regime: how to choose

The new regime is the default. A salaried employee can still pick the old regime each year — here is how the choice works and when it pays.

Tax year 2026-27 · Income-tax Act, 2025 as amended by Finance Act 2026 · reviewed 5 November 2026

The rule

  • Section 202(1): tax is computed under the new regime unless you opt out under 202(4).
  • If you have no business or professional income, you can choose each year — but the opt-out must be made in the original return filed by the due date under section 263(1) (31 July 2027 for 2026-27). A belated or updated return cannot switch to the old regime.
  • If you have business income, the option once exercised continues and can be withdrawn only once (202(4)(a)).
  • Your declaration to the employer only decides TDS; the return decides the final tax.

What you give up in the new regime

  • HRA, LTA, children education and hostel allowances, and other personal allowances not prescribed for the new regime.
  • Professional tax.
  • Interest on a self-occupied house (and set-off of house property loss against salary).
  • Chapter VIII deductions — 80C (123), 80D (126), own NPS ₹50,000 (124(3)), 80E (129), 80G (133), 80GG (134), savings interest (153) and others.
  • Allowed even in the new regime: standard deduction ₹75,000, employer NPS up to 14% (124(2)), Agniveer corpus (125(2)), gratuity, leave encashment and VRS exemptions.
