About this advance tax calculator (FY 2026-27)
This calculator estimates your full-year tax for FY 2026-27 (AY 2027-28) across all five heads of income, compares the old and new regimes, and then breaks the liability into the four advance-tax installments. It also shows the interest under Sections 234B and 234C you avoid by paying on time. Slab rates are unchanged from FY 2025-26.

Senior citizens (60–80) get a ₹3 lakh exemption and super-seniors (80+) ₹5 lakh. The old regime allows 80C, 80D, HRA, home-loan interest and other deductions; the new regime allows only employer NPS under 80CCD(2).
Advance tax & interest saved
If your tax after TDS is ₹10,000 or more, advance tax is due in four installments: 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March. Missing them triggers interest at 1% per month under Section 234C (deferment) and Section 234B (default) — the exact interest a timely payer keeps.
Frequently asked questions
Does the ₹12 lakh rebate cover capital gains?
No. The Section 87A rebate applies only to income taxed at slab rates. Capital gains taxed at special rates (111A, 112A, 112) are taxed even when your total income is within ₹12 lakh.
Can I deduct home-loan interest in the new regime?
For a self-occupied house, no. Interest up to ₹2 lakh is deductible only in the old regime. For a let-out property, interest is allowed against rent, but any resulting loss cannot be set off against other income in the new regime.
How is the basic exemption used against capital gains?
Resident individuals can apply any unused basic exemption limit against special-rate capital gains. This calculator does that automatically, sheltering the highest-taxed gains first.
Are the FY 2026-27 slabs different?
No. The Union Budget kept slab rates, deduction limits and rebates unchanged for FY 2026-27, so the same engine drives both calculators.
