Income Tax Calculator FY 2026-27: New vs Old Regime (India)

1. Pick the financial year. FY 2026-27 for this year's TDS and planning; FY 2025-26 (AY 2026-27) for the ITR you file in 2026. The slabs are the same; only the HRA city list differs.
2. Pick your age. It changes the old regime's basic exemption (₹3 lakh at 60 to 79, ₹5 lakh at 80 and above) and allows 80TTB instead of 80TTA.
3. Enter yearly amounts. Gross salary (with HRA and bonus, without employer PF), Basic + DA, and any employer NPS contribution, interest or other income.
4. Open "Old Regime Deductions" (tap +) and add your items for the comparison: HRA and rent, LTA, professional tax, 80C, NPS, 80D, home loan interest and others. The new regime ignores them.
5. Read the result. Both regimes appear line by line, the lower tax is highlighted, and the verdict shows how much you save and the break-even deductions. Use Copy or Excel to save it.

Example (the default figures): ₹15 lakh salary, Basic ₹6 lakh, HRA and rent ₹2.4 lakh each in Bengaluru, 80C ₹1.5 lakh, 80D ₹25,000. The new regime tax is ₹97,500; the old regime tax is ₹1,45,860, so the new regime saves ₹48,360.

In the new regime, a resident individual with taxable income up to ₹12 lakh gets a rebate of up to ₹60,000 under Section 156 of the Income-tax Act, 2025 (earlier Section 87A). That wipes out the full slab tax of ₹60,000 at ₹12 lakh. Add the ₹75,000 standard deduction and a salary of ₹12.75 lakh pays no tax.

Marginal relief: if taxable income goes a little above ₹12 lakh, the tax cannot be more than the income above ₹12 lakh. For example, at ₹12.25 lakh taxable (₹13 lakh salary) the slab tax is ₹63,750, but the tax is limited to ₹25,000, so you pay ₹26,000 with cess. The relief stops at about ₹12.7 lakh taxable income.

The rebate does not apply to tax on special-rate income such as capital gains, which this calculator does not cover. In the old regime, the rebate is up to ₹12,500 for income up to ₹5 lakh, with no marginal relief.

Use this as a new tax regime calculator by leaving the old regime boxes empty. The new regime (Section 202, earlier 115BAC) has lower rates but very few deductions. For a salaried person it allows:

• Standard deduction of ₹75,000.
• Employer's NPS contribution under 80CCD(2), up to 14% of Basic + DA, for private and government employers alike.
• Exempt employer contributions to PF within the usual limits, and certain allowances not covered here (such as conveyance for official travel).

Not allowed: HRA, LTA, professional tax, 80C, own NPS under 80CCD(1B), 80D, 80E, 80G, 80TTA and interest on a self-occupied home loan. You can see HRA's effect separately with our HRA exemption calculator, and read the rules in how HRA exemption is calculated. To work out the employer NPS deduction, use the NPS employer contribution calculator.

As an old tax regime calculator, it applies these limits to what you enter. For FY 2025-26 returns, use the 1961 Act section numbers; from FY 2026-27, the Income-tax Act, 2025 numbers apply.

A preventive health check-up of up to ₹5,000 is included within the 80D limits. Employee PF and employee NPS under 80CCD(1) count inside the ₹1.5 lakh 80C limit. Read the old tax regime slabs and deductions list for more.

The old regime wins only when your exemptions and deductions (HRA, 80C, 80D, NPS, home loan interest and so on, excluding the standard deduction) are above a break-even amount. Below 60, with salary income only:

The calculator works out your own break-even figure. A salaried person with no business income can choose either regime every year when filing the return by the due date, after telling the employer at the start of the year for TDS. Compare more cases in old vs new tax regime with examples.

The new regime has the same slabs for every age, so a senior citizen with pension or salary up to ₹12.75 lakh pays no tax there. In the old regime, residents aged 60 to 79 have a ₹3 lakh basic exemption and those 80 and above ₹5 lakh. Seniors also get 80TTB (up to ₹50,000 of bank and post office interest) and a ₹50,000 80D limit.

Surcharge is a percentage of the tax. Marginal relief applies just above each threshold: the extra tax and surcharge cannot be more than the income above the threshold. For example, at ₹51 lakh taxable in the old regime, tax plus surcharge is limited to ₹14,12,500 instead of ₹14,76,750, so the total with cess is ₹14,69,000. After surcharge, a 4% health and education cess is added; read more on health and education cess.

From 1 April 2026, the Income-tax Act, 2025 replaced the Income-tax Act, 1961. It uses one term, tax year, in place of "previous year" and "assessment year". So FY 2026-27 is tax year 2026-27, and the return for it is filed in 2027 (what was called AY 2027-28). Rates and limits did not change with the new Act.

• New regime: Section 202 (earlier 115BAC). Rebate: Section 156 (earlier 87A).
• Standard deduction and professional tax: Section 19 (earlier 16). 80C: Section 123. 80D: Section 126.
• Income for FY 2025-26 is still governed by the 1961 Act, so its return uses the old numbers.

• HRA is worked out on Basic + DA for a full year of the same rent. If your rent or salary changed in the year, use our HRA exemption calculator for each period.
• Home loan interest is for a self-occupied house (allowed only in the old regime). Employer contributions to PF, NPS and superannuation above ₹7.5 lakh in total are taxable; this is not checked.
• Results are estimates. Your employer's TDS or your return may differ if your data differs. To see the tax deducted from each month's salary, use the TDS on salary calculator.
