Stop Guessing Which Regime Is Cheaper

Since the new tax regime became the default, deciding between it and the old regime has become a genuine calculation, not a formality — and the right answer depends entirely on your actual income and how many deductions you can claim. This calculator runs both regimes on the same income at once and marks whichever comes out cheaper, so the comparison is based on your real numbers instead of a generic rule of thumb that may not apply to you.

How to Use This Calculator

  1. 1Enter your annual incomeYour yearly salary before tax (or business income), plus any interest or rent received.
  2. 2Set your age and income typeSalaried people and pensioners get a standard deduction; senior citizens get higher old-regime limits.
  3. 3Add your old-regime deductions80C, 80D, NPS, home loan interest and HRA — each limit is applied for you. There's a helper to work out HRA.
  4. 4See which regime is cheaperThe saving, the full working for both regimes, and how much in deductions the old regime needs to win.

Old Regime vs New Regime — What Actually Differs

  1. 1The new regime has lower rates but fewer deductionsSince Budget 2025, the new regime charges nothing on taxable income up to ₹12 lakh (₹12.75 lakh of salary after the ₹75,000 standard deduction) and has lower rates above it — but it doesn't allow most deductions and exemptions (80C, HRA, 80D, home loan interest on a self-occupied home) that the old regime does.
  2. 2The old regime rewards claiming deductionsIf you actively invest in 80C instruments, pay rent and claim HRA, or have a home loan, the old regime's deductions can bring your taxable income down enough to outweigh its higher headline rates.
  3. 3There's no universal answer — it depends on your actual deductionsSomeone with minimal deductions is very likely better off under the new regime's lower rates. Someone claiming substantial 80C, HRA, and home loan interest deductions may still come out ahead under the old regime — which is exactly why comparing both with your real numbers matters more than a general rule of thumb.

Frequently Asked Questions

Which tax slabs does this calculator use?

The rates for FY 2025-26 (AY 2026-27), which Budget 2026 kept unchanged for tax year 2026-27. New regime: nil up to ₹4 lakh, then 5%, 10%, 15%, 20%, 25% in ₹4 lakh steps, and 30% above ₹24 lakh. Old regime: nil up to ₹2.5 lakh (₹3 lakh for 60–79, ₹5 lakh for 80+), 5%, 20%, and 30% above ₹10 lakh. Rates are from the Income Tax Department's official summary.

Is income up to ₹12 lakh tax-free in the new regime?

Yes, for income taxed at normal slab rates. The Section 87A rebate of up to ₹60,000 cancels the tax on taxable income up to ₹12 lakh — so a salary up to ₹12.75 lakh pays nothing after the standard deduction. Just above ₹12 lakh, marginal relief caps your tax at the amount your income exceeds ₹12 lakh, so earning a little more never leaves you worse off.

Which regime should I choose?

Whichever costs less for your real income and deductions — the result shows the saving and the break-even: the amount of old-regime deductions at which both regimes cost the same. Most people with modest deductions pay less in the new regime; people with large HRA, home loan interest and 80C claims can still save with the old one.

Why do deductions only change the old regime?

The new regime doesn't allow most deductions — 80C, 80D, HRA, 80CCD(1B) and home loan interest on a self-occupied home. It does allow the standard deduction for salaried people and pensioners, and the employer's NPS contribution under 80CCD(2), which is why that field counts in both.

Does it include surcharge and cess?

Yes. Surcharge of 10%, 15% and 25% applies above ₹50 lakh, ₹1 crore and ₹2 crore (37% above ₹5 crore in the old regime; the new regime is capped at 25%), with marginal relief at each threshold. A 4% health and education cess is added to the tax plus surcharge.

Does this calculator cover capital gains?

No — it covers salary, pension, business and other income taxed at normal slab rates. Capital gains taxed at special rates (for example on shares and mutual funds) follow separate rules and don't get the ₹12 lakh rebate, so check those with a chartered accountant.

Is my income sent anywhere?

No. Every calculation happens in your browser — nothing you enter is sent to or stored on a server.
