Why You Need an Income Tax Calculator
Tax season in India brings a familiar anxiety: how much will I actually pay? The income tax calculator on this page takes the guesswork out of that question. Whether you’re a salaried employee, freelancer, or business owner, knowing your tax liability before filing is the first step to smart planning. With the new regime and old regime both on the table, a reliable tax calculator helps you choose the option that keeps more money in your pocket.
Old Regime vs New Regime: What Changed
The new tax regime, introduced under the Income Tax Act, offers lower tax rates but removes most deductions like Section 80C, 80D, and HRA. The old regime keeps those deductions but applies higher slab rates. There’s no one-size-fits-all answer—your salary structure, investments, and home loan interest all decide which one wins. That’s exactly why an income tax calculator matters: it computes both options in seconds and shows you the difference in black and white.
FY 2025-26 Tax Slabs You Should Know
Under the new regime for FY 2025-26 (AY 2026-27), income up to ₹4 lakh is tax-free. From ₹4–8 lakh it’s 5%, ₹8–12 lakh is 10%, ₹12–16 lakh is 15%, ₹16–20 lakh is 20%, ₹20–24 lakh is 25%, and above ₹24 lakh it’s 30%. The old regime still follows the classic slabs: ₹2.5 lakh free, 5% up to ₹5 lakh, 20% up to ₹10 lakh, and 30% beyond. The standard deduction of ₹75,000 (new) and ₹50,000 (old) is applied automatically by our tax calculator.
Rebate u/s 87A: Zero Tax for Many
Under the new regime, if your taxable income is up to ₹12 lakh, the rebate under Section 87A wipes out your entire tax liability. Under the old regime, the rebate applies up to ₹5 lakh. Millions of middle-class taxpayers qualify for this rebate—many without realizing it. A quick run through a salary calculator and tax tool can confirm whether you owe anything at all.
How Our Income Tax Calculator Works
Enter your annual income, your deductions under 80C/80D (these apply only to the old regime), and pick a regime. The calculator applies the correct slabs, standard deduction, rebate, and 4% health and education cess automatically. The result shows your total tax, effective tax rate, and a side-by-side comparison of both regimes so you can pick the cheaper one. It’s the same math the Income Tax Department uses, minus the confusion.
Tips to Lower Your Taxable Income
If the old regime works for you, max out Section 80C (₹1.5 lakh) with PPF, ELSS, or EPF, claim Section 80D health insurance premiums, and use your HRA exemption properly. Under the new regime, there are few deductions—but the lower rates and higher rebate often win anyway. Use our PPF calculator to see how a 15-year PPF investment grows tax-free.
Frequently Asked Questions
How much income is tax-free in India in 2025-26?
Under the new regime, income up to ₹4 lakh is tax-free before the standard deduction. With the ₹75,000 standard deduction, salaried income up to ₹12 lakh pays zero tax thanks to the Section 87A rebate.
Is the old or new regime better for salaried employees?
It depends on your deductions and salary. Employees claiming more than about ₹3 lakh in deductions and exemptions usually do better under the old regime; everyone else often benefits from the new regime’s lower slabs and rebate.
How is TDS calculated on salary?
Your employer estimates your annual income, applies the regime you chose, deducts the standard deduction and any declarations you made, then divides the resulting tax by 12 to arrive at monthly TDS.
