Tax year 2026-27 (FY 2026-27) Rules checked on 7 October 2026

What this calculates

  • Resident individuals under 60 with salary or pension income
  • Total income up to ₹50,00,000, so no surcharge
  • Income taxed at normal slab rates only: no capital gains, dividends, winnings, crypto, rent or business income
  • An estimate for Tax year 2026-27 (FY 2026-27), not tax advice and not a return

1 Your income

₹
Your total pay for the year before any deduction, as in your Form 16. Pension counts as salary. Include your employer's NPS contribution if it is part of the amount.
₹
For example, interest you earn. Do not include capital gains, dividends, winnings, rent or business income: they are not supported.
₹
Needed only for the HRA exemption and the employer NPS limit. DA counts if your terms of employment provide it.
2 Deductions that apply to you Old regime only, unless stated

This calculator does not check that you are eligible. Enter what you are sure of; each limit is applied for you. The new regime allows almost none of these.

₹
Such as life insurance premium and provident fund contributions (the full list is in Schedule XV of the Act). Limit ₹1,50,000.
₹
Your contribution, not your employer's. Limit ₹50,000 (section 124(3)).
₹
Premium paid, none of them aged 60 or more. Limit ₹25,000 (section 126).
₹
Premium paid for your parents (section 126).
Under 60: limit ₹25,000. Aged 60 or more: ₹50,000. If only one is 60 or more, enter the total allowed in "Other eligible deductions" instead.
₹
Tax on employment deducted from your salary.
₹
Interest for the year on a loan for your own home. Not for a house you let out. Old regime only.
Buying or building, finished within five years of the year you borrowed: limit ₹2,00,000 (section 22). Anything else, such as repairs: ₹30,000.

To estimate a year's interest, use the Home Loan Calculator.

House rent allowance (HRA), old regime only

Worked out from rule 279 of the Income-tax Rules, 2026, for a full year in one city with one landlord. Uses your Basic salary plus DA above.

₹
₹
The 50% cities are Mumbai, Kolkata, Delhi, Chennai, Hyderabad, Pune, Ahmedabad and Bengaluru.
Advanced
₹
The limit is a share of your Basic salary plus DA (entered above): 14% in the new regime, 10% in the old (14% if your employer is the Central or a State Government).
₹
Anything else you are sure the old regime allows, for example interest on an education loan. The calculator does not check eligibility or limits for this amount.

How to Use the Old vs New Tax Regime Calculator

  1. Enter your annual salary or pension income. The standard deduction is applied for you.
  2. Open "Deductions that apply to you" and add what you are sure of. The limits are applied for you and shown.
  3. Read the estimated tax under each regime and the difference. Open the breakdown to see how each was worked out.
  4. The break-even shows how much old-regime deduction would make the two equal, so you can see how far your deductions are from it.

How the Two Regimes Differ for Tax year 2026-27 (FY 2026-27)

The new regime (section 202 of the Income-tax Act, 2025) has lower slab rates, a ₹75,000 standard deduction and a rebate that makes income up to ₹12,00,000 tax-free, with marginal relief just above it. It does not allow the old regime's exemptions and deductions, such as HRA, the section 123 (80C) deduction, health insurance, own NPS contributions, home loan interest on the house you live in and professional tax. It does allow the employer's NPS contribution.

The old regime has higher slab rates, a ₹50,000 standard deduction, a rebate only up to ₹5,00,000 of total income, and the deductions this calculator lets you enter. Both add 4% Health and Education Cess, and the final amount is rounded to the nearest ten rupees (section 516).

What This Does Not Cover

It does not calculate business or professional income, capital gains, dividends, lottery or online-game winnings, crypto, foreign income, agricultural income, rent from a house you let out or a loss on one, arrears relief, family pension, senior citizens (60 and above), non-residents, part-year or multiple-employer cases, or income above ₹50,00,000. It assumes one tax year and one house you live in. It does not check that a deduction is allowed, and it is not tax or legal advice. Your actual return may differ; for anything complex, check the official sources above or ask a qualified professional.

Old vs New Tax Regime Calculator FAQ

Is my income or any number sent anywhere?

No. The calculation runs in your browser and nothing is uploaded or stored; reloading clears it.

Why is there a limit of ₹50,00,000?

Above ₹50 lakh of total income, surcharge applies, with its own thresholds and relief. This version does not calculate it, so it refuses higher incomes instead of giving a misleading number.

What is the break-even?

It is the amount of old-regime deductions and exemptions (not counting the standard deduction) at which the old regime's estimated tax falls to the new regime's. Since more deduction never raises the old regime's tax, there is one such point. It is shown to the nearest ₹1,000.

How is the HRA exemption worked out?

It is the least of the HRA you receive, the rent you pay minus 10% of your Basic salary plus DA, and 50% of that salary if you live in Mumbai, Kolkata, Delhi, Chennai, Hyderabad, Pune, Ahmedabad, Bengaluru or 40% elsewhere (rule 279 of the Income-tax Rules, 2026). If your case is different, enter the exemption yourself.

Why is the tax a multiple of ten?

The Act rounds total income and the amount payable to the nearest ten rupees (section 516), so that is how the estimate is rounded.
