In India, there are two Income Tax regime options (FY 2026-27 = tax year 2026-27 under the Income-tax Act, 2025; slabs and rates unchanged from FY 2025-26): the Old Regime (deductions allowed but higher rates) and the New Regime (most deductions not available but with lower rates + standard deduction of Rs 75,000).

New Regime slabs (FY 2026-27): 0-4L = 0%, 4-8L = 5%, 8-12L = 10%, 12-16L = 15%, 16-20L = 20%, 20-24L = 25%, 24L+ = 30%. Standard deduction Rs 75,000. Rebate u/s 87A up to taxable income Rs 12L = zero tax (effectively up to ~Rs 12.75L gross income tax-free).

Old Regime slabs: 0-2.5L = 0%, 2.5-5L = 5%, 5-10L = 20%, 10L+ = 30%. Standard deduction Rs 50,000. Plus deductions: Sec 80C (Rs 1.5L PPF/ELSS/insurance/home loan principal), 80D (health insurance Rs 25K self + 50K parents), 80CCD (NPS Rs 50K additional), 80G (donations), 80E (education loan interest), Sec 24(b) (home loan interest Rs 2L for self-occupied), HRA exemption.

This free calculator takes gross salary, savings (80C/80D/etc), HRA components, home loan interest, and donations as input, computes tax in both regimes, and displays them side-by-side. It shows which regime gives the lower tax on your numbers ("Old Regime: Rs X lower" or "New Regime: Rs Y lower").

General rule of thumb: if total deductions across 80C + 80D + Sec 24 + HRA add up to Rs 4L+, the Old Regime often gives the lower tax. Below Rs 3L in deductions, the New Regime often does (its rates are lower). Run both on your own numbers.

Illustration only — not tax advice. Tax depends on your full income, the regime you choose and the law in force; please consult a Chartered Accountant (CA) before acting on it.

The calculator also computes surcharge (10% above 50L, 15% above 1Cr, 25% above 2Cr, 37% above 5Cr — capped at 25% in the New Regime) and a 4% Health & Education Cess on total tax. Surcharge carries marginal relief: when income just crosses a threshold, the extra tax cannot exceed the extra income, so a few thousand rupees over ₹50 lakh does not suddenly cost lakhs. The rebate under Section 87A (full up to ₹12 lakh taxable in the New Regime, ₹5 lakh in the Old) carries its own marginal relief the same way.

Frequently Asked Questions

Why is the New Regime the default?
In Budget 2023, the New Regime was made the default to simplify compliance — it is easier for most taxpayers (non-investors). The standard deduction was increased to Rs 75K (Rs 50K in Old). A salaried taxpayer can still choose the Old Regime each year in the return itself; a taxpayer with business income has a limited option to switch, made through a separate form before the due date.
How much 80C deduction do you get in the Old Regime?
A maximum of Rs 1.5 lakh combined across PPF, ELSS, LIC premium, home loan principal repayment, EPF employee contribution, NPS Tier-1 (under 80C), Sukanya Samriddhi, tax-saver FD (5-yr), NSC, tuition fees for 2 children. Important: 80C max is Rs 1.5L TOTAL, not per item.
Do salaried individuals get the standard deduction in the New Regime?
Yes — a Rs 75,000 standard deduction is available to salaried employees and pensioners in the New Regime too (increased in Budget 2024). Effectively, this makes gross income up to ~Rs 12.75L tax-free under the New Regime due to the 87A rebate.
Is HRA exemption available only in the Old Regime?
Yes, HRA exemption u/s 10(13A) is available only in the Old Regime. HRA is not exempt in the New Regime. Formula: min of (a) actual HRA received, (b) 50% of basic salary in Mumbai, Delhi, Kolkata, Chennai, Bengaluru, Hyderabad, Pune or Ahmedabad (40% elsewhere), (c) actual rent paid minus 10% of basic. Rent receipts and PAN of the landlord (if annual rent > Rs 1L) are required.
How do you get the extra Rs 50K NPS deduction?
Under Sec 80CCD(1B), an additional Rs 50,000 is available on NPS Tier-1 contributions, ON TOP of the Rs 1.5L 80C limit. Old Regime only. Employer NPS contribution (old 80CCD(2), now s.124 of the Income-tax Act 2025) is deductible in both regimes: up to 14% of salary (basic + DA) in the New Regime, and in the Old Regime 10% (14% for government employers). Employer contributions to PF, NPS and superannuation together above ₹7.5 lakh a year are taxable. Both self-employed and salaried are eligible.
