No. Your tax amount is exactly the same. All slabs, rates, deductions unchanged. The Act only changed the rulebook, not the rules.

Your July 2026 filing (FY 2025-26) is still under the old Act. First new Act filing = July/August 2027 for Tax Year 2026-27.

Yes, 100%. PAN, TAN, all previous filings, pending cases — all valid. New Act doesn't go backwards.

Yes. Both continue. New regime = default. For old regime: tell employer via Form 124 and file ITR by July 31. Miss it? You're stuck with new regime.

Update software to Sec 392/393/394. Use challan codes 1001-1067. Switch to Form 124, 130 etc. Update HRA for 8 cities. All TDS from April 2026 uses new references.

Original RBI issue buyers = still tax-free at maturity. Secondary market buyers = now taxable as capital gains even at maturity.
