Documents you need to support this filing

Based on the figures you entered, these are the documents that back this calculation when you actually file. Generate them in seconds — no signup, your data stays in your browser.

Have you got compliant rent receipts for the HRA you just calculated?

Section 10(13A) requires monthly rent receipts (with landlord PAN if annual rent crosses ₹1 lakh). Form 12BB submission to your employer needs them. Your inputs imply ₹3,00,000/year of rent, which is 12 monthly receipts.

Need a clean salary slip showing the gross figure you used above?

Banks, NBFCs, visa officers, and ITR scrutiny match the gross figure on your slip against your declared income. A clean monthly slip with the 12 mandatory fields is what they ask for.

Generate salary slip ₹4 per slip

Have payment receipts for your 80C / 80D / NPS investment proofs?

80C, 80D, and 80CCD(1B) claims need primary payment evidence: premium receipts, PPF deposit slips, NPS contribution receipts. A clean payment receipt with UTR is the cleanest audit trail when scrutiny lands.

Generate payment receipts ₹4 / receipt

Section 89(1) — salary-arrears reliefTick this if you received arrears of salary, advance salary, family-pension arrears, or premature PF withdrawal this year. Section 89(1) read with Rule 21A protects you from being pushed into a higher slab because multiple years of pay landed in one FY. The relief recalculates tax as if the arrears had been received in the years they pertain to.

FAQ

Income tax calculator — common questions

How is the FY 2026-27 income tax calculator different from previous years?

Two changes effective 1 April 2026 affect FY 2026-27 calculations. Rule 279 of the Income-tax Rules 2026 (CBDT notification, 20 March 2026) expanded the HRA 50% metro list from 4 cities (Delhi, Mumbai, Kolkata, Chennai) to 8 by adding Bengaluru, Hyderabad, Pune, and Ahmedabad. The Section 87A rebate under the new regime is Rs. 60,000 (raised from Rs. 25,000 by Finance Act 2025), making salary up to Rs. 12,75,000 effectively tax-free under the new regime.

Does this calculator handle Section 89(1) salary-arrears relief?

Yes. Tick the Section 89(1) checkbox to enter total arrears received this year and per-prior-year gross income. The calculator applies the Rule 21A formula (relief = current-year tax delta minus the sum of would-have-been prior-year deltas) and shows the working. Form 10E must be filed online on the e-filing portal before submitting the ITR to claim the relief; the calculator displays this reminder prominently.

Is my salary or rent data sent to any server?

No. The calculator is a pure client-side computation. Your salary, basic, HRA, rent, PAN, deductions, and arrears figures live only in your browser tab. No form submission to any server occurs at any point. Refresh the page or close the tab and the data is gone.

Which deductions does the Old regime path support?

Standard deduction (Rs. 50,000), HRA exemption under Section 10(13A) and Rule 279, Section 80C up to Rs. 1,50,000 (PPF / ELSS / EPF / life insurance / principal repayment), Section 80D up to Rs. 25,000 (health insurance, self + family under 60), Section 80CCD(1B) up to Rs. 50,000 (NPS additional), and Section 24(b) up to Rs. 2,00,000 (home loan interest, self-occupied).

When does the New regime win versus Old?

Rule of thumb: if your total deductions (HRA + 80C + home loan interest + 80D) exceed roughly Rs. 4-5 lakh, the Old regime is usually better. Below that, the New regime wins on lower slab rates and the Rs. 12 lakh tax-free ceiling under Section 87A. The breakeven shifts as the New regime slabs widen, so re-run the calculation each year after the Union Budget.
