What Changed in FY 2025-26

The Union Budget 2025 (presented February 2025) introduced significant changes to the new tax regime effective from FY 2025-26 (AY 2026-27):

The most important change: Income up to ₹12 lakh is now effectively zero-tax under the new regime (₹12.75 lakh for salaried employees after the ₹75,000 standard deduction). This makes the new regime the obvious choice for most taxpayers below this threshold.

💡

Crossover point: For most salaried taxpayers, the old regime becomes more beneficial only when total deductions exceed approximately ₹4–5 lakh. Use ToolLoom's Income Tax Calculator to find your exact crossover point.

Surcharge and Cess

₹50L – ₹1 Cr10%10%

₹2 Cr – ₹5 Cr25%25%

The 4% Health & Education Cess applies on (tax + surcharge) for all taxpayers. Marginal relief is available to prevent the effective rate from exceeding 100% at surcharge thresholds.

Switching Between Regimes

Salaried employees can declare their preferred regime to their employer at the start of each financial year. They can switch every year — new regime one year, old regime the next, based on their deduction profile that year.

Business owners who have opted out of the new regime cannot return to it in future years, except under specific conditions. This is an important consideration for self-employed professionals and partners in firms.

⚠️

Default regime: If you don't declare your preference to your employer or choose a regime in your ITR, the new regime is applied automatically. Always make an active choice based on your actual deductions.

Frequently Asked Questions

For FY 2025-26 (AY 2026-27), the new regime slabs are: up to ₹4 lakh nil, ₹4-8 lakh 5%, ₹8-12 lakh 10%, ₹12-16 lakh 15%, ₹16-20 lakh 20%, ₹20-24 lakh 25%, above ₹24 lakh 30%. The old regime remains: up to ₹2.5 lakh nil, ₹2.5-5 lakh 5%, ₹5-10 lakh 20%, above ₹10 lakh 30%.
Surcharge applies only on incomes above ₹50 lakh. Rates under new regime: 10% surcharge for ₹50L-₹1Cr, 15% for ₹1Cr-₹2Cr, 25% for ₹2Cr-₹5Cr, 25% for above ₹5Cr (capped at 25% under new regime). Under the old regime, the top surcharge remains 37% for income above ₹5Cr. A 4% Health and Education Cess applies on tax plus surcharge.
Marginal relief ensures that the additional tax you pay on income just above a threshold is not more than the additional income itself. If your income is ₹51 lakh, the surcharge would push your effective tax rate up sharply. Marginal relief caps the additional tax to the additional income above the threshold, preventing an effective tax rate above 100% on the marginal rupee.
Salaried employees (without business income) can switch between old and new regime every financial year by declaring their choice to their employer at the start of the year. Business owners who opt out of the new regime cannot return to it in subsequent years except once in a lifetime. If no choice is declared, the new regime is applied by default.
For individuals and HUFs not under tax audit, the ITR filing due date is 31 July of the assessment year (i.e., 31 July 2026 for FY 2025-26). Late filing attracts a penalty of ₹5,000 (₹1,000 if income is below ₹5 lakh). Late filing also prevents carrying forward certain losses to future years.
