Income Tax Calculator
Calculate income tax for FY 2025-26 under old and new tax regimes.
About Income Tax Calculator
The Income Tax Calculator on ToolsOfIndia is a free browser-based tool built for salaried taxpayers and small business owners. Indian financial paperwork is unforgiving, so this calculator stays strict about formulas, rounding and the small details that decide whether a figure matches your actual filing. Enter your income, deductions and regime, and the calculator applies the FY 2025-26 slabs for both old and new regimes, the standard deduction of Rs 75,000 under the new regime and Rs 50,000 under the old, and the 87A rebate that now removes tax on incomes up to Rs 12 lakh under the new regime. 80C, 80D, HRA and home loan interest deductions are accepted under the old regime, and the tool compares both regimes so you pick the lower liability. Surcharge on incomes above Rs 50 lakh and the 4 per cent health and education cess are applied automatically, so the final figure matches what a tax return will demand. Typical moments to reach for it: deciding between old and new regime, estimating TDS for the year, or planning an 80C investment to cut tax. Everything is free with no usage caps, and nothing asks for your email address.

How to save income tax in India?
Use Section 80C (up to Rs. 1.5L for PPF, ELSS, life insurance), 80D (health insurance), NPS under 80CCD(1B) (extra Rs. 50,000), and HRA exemption for salaried employees.
Which tax regime is better for me?
The new regime is simpler with lower rates but no deductions. The old regime benefits those with significant deductions. Use our calculator to compare both regimes for your income.
What are the new regime slabs for FY 2025-26?
Up to Rs 4 lakh nil, 4 to 8 lakh at 5 per cent, 8 to 12 at 10, 12 to 16 at 15, 16 to 20 at 20, 20 to 24 at 25, and above 24 lakh at 30 per cent.
Is income up to Rs 12 lakh tax-free?
Under the new regime, the 87A rebate removes tax on incomes up to Rs 12 lakh, but this is a rebate, not an exemption, so it applies after slab computation.
