How this works
The FY 2025-26 slabs (Budget 2025)
New regime (the default). Standard deduction ₹75,000 for salaried, then:
Section 87A rebate: if your total income is up to ₹12,00,000, your tax is fully rebated to zero (with marginal relief just above that line). So a salaried person can earn up to ~₹12.75L tax-free.
Old regime. Standard deduction ₹50,000 for salaried, basic exemption ₹2.5L (₹3L if 60–80, ₹5L if 80+), then ₹2.5–5L. 5% · ₹5–10L. 20% · above ₹10L. 30%. Rebate makes tax zero up to ₹5L taxable. You can subtract 80C/80D/HRA/home-loan deductions.
Both add 4% health & education cess, plus surcharge on higher incomes (10% over ₹50L, 15% over ₹1cr, 25% over ₹2cr; the old regime adds a 37% slab over ₹5cr, which the new regime does not).
Old vs new. How to choose
The new regime has lower rates and a big rebate but ignores most deductions. The old regime has higher rates but lets you subtract 80C, 80D, HRA, and home-loan interest. The rule of thumb: if you claim large deductions (home loan + full 80C + HRA), the old regime can still win; if you don't, the new regime almost always does. This tool computes both so you don't have to guess.
Advance tax & presumptive (for business owners)
Advance tax is due if your tax for the year exceeds ₹10,000. Pay it in instalments: 15% by 15 Jun, 45% by 15 Sep, 75% by 15 Dec, 100% by 15 Mar. Missing dates attracts interest under sections 234B/234C.
Presumptive taxation can simplify life if you qualify:
Section 44AD (small business). Declare 8% of turnover as profit (6% for digital receipts), turnover up to ₹2 crore (₹3 crore if cash receipts are ≤5%). No detailed books required.
Section 44ADA (professionals. Consultants, doctors, lawyers, etc.). Declare 50% of gross receipts as profit, receipts up to ₹50 lakh (₹75 lakh if cash ≤5%).
Under presumptive, enter the presumptive profit as your income above to estimate the tax on it.
Bookkeeping. The records you must keep
Whether or not you're under presumptive tax, a clean set of books protects you in an assessment and makes filing painless:
Bank reconciliation. Match every entry in your books to the bank statement, monthly. This is the single most important habit.
Sales & purchase registers. Every invoice raised and received, with GST where applicable.
Cash book. All cash in and out; keep cash transactions small and documented.
Expense vouchers. A bill or receipt for every expense you claim. No receipt, no deduction.
Fixed-asset register. What you own, when bought, and depreciation.
TDS records. Tax deducted on payments you make (rent, contractors, professional fees) and deposited on time; issue Form 16/16A.
GST returns & reconciliation. GSTR-1 vs 3B vs books vs 2B, monthly or quarterly.
Retain for 6+ years. The income-tax department can reopen older years; keep records accordingly.
Heads-up. What changes from FY 2026-27: A new Income-tax Act, 2025 replaces the Income-tax Act, 1961 with effect from 1 April 2026 (the new "Tax Year 2026-27"). The year this tool covers. FY 2025-26 (AY 2026-27). Is governed by the current law and the Budget-2025 slabs above, so these figures stand. Under the new Act the slab rates are unchanged, but the framework is new: "Tax Year" replaces "Assessment Year", some deduction limits and allowances are revised, and ITR forms/due dates change (e.g., ITR-3/4 to 31 Aug). We'll refresh this tool once the Tax Year 2026-27 rules are notified.
This is an estimate and general information, not tax advice. It models a resident individual/HUF on FY 2025-26 (AY 2026-27) slabs and does not cover capital gains, multiple income heads, clubbing, set-off of losses, foreign income, every surcharge edge case, or marginal-relief nuances beyond the new-regime rebate. Nothing is sent anywhere. Confirm your actual liability with a Chartered Accountant before filing or paying.
Beyond a calculator
The savings are in the structure, not the slab.
Regime choice, presumptive vs books, salary-vs-dividend for founders, capital gains timing. The real optimisation needs someone who knows both the rules and your business. Unfolding Values works with founders across India and the US on exactly this.
