Full ITR-style computation for AY 2027-28 (IT Act, 2025) and AY 2026-27 (IT Act, 1961) with head-wise income — Salary, House Property, Business, Capital Gains (111A / 112A / VDA) and Other Sources — correct Section 87A rebate treatment on special-rate income, loss set-off, marginal relief, surcharge, cess and interest u/s 234A/234B/234C. Old vs New Regime, side by side. Runs 100% in your browser.
Budget 2026 made no change to slab rates — both years use identical slabs, rebate and cess. Due dates and interest anchors adjust automatically.
Standard deduction auto-applied: ₹75,000 (New) / ₹50,000 (Old).
30% standard deduction u/s 24(a) auto-applied on Net Annual Value.
HP loss set-off against other heads capped at ₹2,00,000; balance carried forward (shown in notes).
Business loss is set off against other heads except Salary (Sec 71(2A)). Unabsorbed loss shown as carry-forward.
Enter capital losses as negative in the relevant field (except VDA — losses ignored by law).
Old Regime only, except 80CCD(2) which both regimes allow.
80TTA (₹10,000) / 80TTB for seniors (₹50,000) auto-computed from savings interest.
Advance tax paid instalment-wise (for Sec 234B/234C):
If you fill only the single "Advance Tax" box above, it is treated as paid by 15 Mar (of the relevant FY) — interest u/s 234C on earlier instalments will apply accordingly.
Due date assumed 31 July 2027 (non-audit case). Interest @ 1% per month or part thereof.
Fill in each income head on the left (open only the heads you need) and press Compute. You get the complete statement for both regimes: head-wise income → Gross Total Income → deductions → Total Income → tax split between slab-rate and special-rate income (111A, 112A, 112, VDA) → 87A rebate with correct special-rate exclusion → marginal relief → surcharge → cess → TDS/advance tax → self-assessment tax or refund.
Disclaimer: For resident individuals, FY 2026-27 (AY 2027-28) and FY 2025-26 (AY 2026-27). Simplified treatment of loss set-off ordering, surcharge marginal relief, and capital-gains surcharge capping; AMT, clubbing, and carried-forward losses of earlier years are not modelled. Section 87A rebate against special-rate income follows the Finance Act 2025 position as continued by the Finance Act 2026 (rebate not available against income taxed at special rates). Interest u/s 234A/234B/234C is computed on a simplified basis (due date assumed as selected; part of a month counted as a full month; Rule 119A rounding applied).
