What are the income tax slabs for FY 2025-26?

Under the new regime: up to Rs 4 lakh nil, 4-8 lakh 5%, 8-12 lakh 10%, 12-16 lakh 15%, 16-20 lakh 20%, 20-24 lakh 25%, and above 24 lakh 30%. The old regime uses 2.5/5/10 lakh slabs at 5%, 20% and 30%.

Is income up to Rs 12 lakh tax-free?

Under the new regime for FY 2025-26, a Section 87A rebate makes tax effectively zero for taxable income up to Rs 12 lakh. With the Rs 75,000 standard deduction, a salaried person earning up to about Rs 12.75 lakh can pay zero tax.

Which regime should I choose?

The new regime has lower rates but few deductions. The old regime has higher rates but allows 80C, 80D, HRA, home loan interest and more. If your deductions are large, the old regime can be cheaper. This calculator compares both for you.

What is the standard deduction?

Salaried taxpayers and pensioners get a standard deduction from salary income: Rs 75,000 under the new regime and Rs 50,000 under the old regime, applied automatically.

What is the income tax calculator?

This calculator computes your income tax liability for FY 2025-26 under both the new tax regime (default from FY 2023-24) and the old tax regime. It accounts for standard deduction, Section 87A rebate and 4% health and education cess. Under the new regime, slabs are wider and rates lower, but most deductions (80C, HRA, LTA, home-loan interest, etc.) are not allowed. Under the old regime, deductions are available but slabs are narrower. The right choice depends on how many deductions you can claim.
