- Form 16 from your employer for the gross salary figure (Part B).
- Salary slip (any one month) for the HRA component.
- Rent receipts and landlord PAN (required if rent paid is over Rs 1 lakh per year).

- AIS / Form 26AS downloaded from incometaxindia.gov.in for capital gains data.
- 80C proofs: LIC premium receipts, ELSS statements, PPF passbook, ULIP receipts, tuition fee receipts, principal repayment certificate.
- Taxable income — salary plus other normal-rate income after standard deduction (and after Old Regime deductions in the Old column). Capital gains are not included here; they are taxed separately.
- Slab tax — tax computed on taxable income using the FY slabs. This is your tax before any rebate.
- Section 87A rebate — reduces only the slab tax, only if eligible. Shown as a negative number. Never reduces capital gains tax.
- Capital gains tax — STCG plus LTCG tax at the special rates. Always payable in full regardless of total income or rebate eligibility.
- Total tax — final liability including 4 per cent Health and Education Cess. This is what you owe (or what TDS should have already collected). Compare across regimes; pick the lower one.

This calculator is for illustrative purposes only. It uses estimated basic salary (40 per cent of gross) for HRA calculation, which is an industry-standard assumption and may differ from your actual pay structure. Marginal relief on surcharge thresholds is not modelled. Results do not constitute tax advice. Consult a Chartered Accountant for your specific situation. Use the official tax calculator at incometaxindia.gov.in for filing decisions.
How to use this calculator
Step 1. Pick the financial year that matches the income you want to compute. FY 2025-26 (AY 2026-27) covers income earned between 1 April 2025 and 31 March 2026, filed by 31 July 2026. FY 2024-25 and FY 2023-24 are available for older filings or revised returns.
Step 2. Enter your gross annual salary (the figure on your Form 16, before any deductions) and any other income at normal slab rates. Then enter any capital gains. For FY 2024-25, you must split equity STCG/LTCG into pre-23-July-2024 and post-23-July-2024 buckets because Finance Act 2024 raised the rates mid-year.
Step 3. If you want a fair comparison against the Old Regime, enter your deduction stack: HRA received, rent paid, 80C investments, 80D health insurance, 24(b) home loan interest, and 80CCD(1B) NPS. The calculator will compute the HRA exemption using the standard three-condition rule and apply the section caps automatically.
Click Calculate. The output shows New Regime and Old Regime side by side, with the recommended regime highlighted in green. A short narrative explains how the Section 87A rebate was applied (or denied) and flags the capital gains carve-out if applicable.
Which regime is right for you?
For FY 2025-26, the New Regime wins for most salaried Indians earning up to roughly Rs 20 lakh with modest deduction stacks. The combination of Rs 75,000 standard deduction and Rs 60,000 Section 87A rebate makes salary up to Rs 12.75 lakh effectively tax-free, and the 15 to 25 per cent marginal rate bands above that stay below the Old Regime's flat 30 per cent above Rs 10 lakh of taxable income.
The Old Regime retains a genuine case for filers whose deductions are large and durable: an active home loan delivering Rs 2 lakh of Section 24(b) interest, a metro HRA claim worth Rs 2 to 3 lakh, Section 80C and 80D both at their caps, and an additional NPS contribution under 80CCD(1B). When that full stack exceeds approximately Rs 4 lakh above the Old Regime's standard deduction, the comparison becomes worth running carefully. Enter your numbers in the calculator above to confirm.
Section 87A and capital gains: the rule that catches equity investors
The Section 87A rebate is one of the most-misunderstood provisions in Indian income tax. The rebate applies only to tax computed at normal slab rates. Tax on capital gains taxed at special rates under Sections 111A (STCG on listed equity, 20 per cent), 112A (LTCG on listed equity, 12.5 per cent above Rs 1.25 lakh), and 112 (LTCG on other assets, 12.5 per cent) is never eligible for the rebate, regardless of total income level.
Equally important, the threshold check for 87A eligibility (Rs 12 lakh under the New Regime for FY 2025-26, Rs 7 lakh under FY 2023-24 and FY 2024-25) applies to normal-rate income only. Capital gains are not added to the threshold calculation. This is the dominant CA practice and how the income tax portal itself processes returns, supported by CBDT Circular No. 13/2025 read holistically. The calculator above implements this rule correctly: a salaried filer with Rs 10 lakh salary and Rs 3 lakh STCG sees salary tax netted to zero by the rebate but pays Rs 60,000 STCG tax plus 4 per cent cess for a total demand of Rs 62,400.
