Estimated tax
How it's calculated
India's New Regime uses a progressive slab system: only the slice of your income that falls inside each slab is taxed at that slab's rate. You do not pay the top rate on your whole income.
For each slab the calculator takes the part of your income between the slab's lower and upper bound and multiplies it by the slab rate. It adds all the slab amounts together to get the tax before cess, then adds a 4% health & education cess on that figure to get your total liability.
Worked example on ₹15,00,000: nil on the first ₹4,00,000; 5% on the next ₹4,00,000 = ₹20,000; 10% on the next ₹4,00,000 = ₹40,000; 15% on the remaining ₹3,00,000 = ₹45,000. Tax before cess = ₹1,05,000, plus 4% cess (₹4,200) = ₹1,09,200.
Slabs as of FY2025-26 — verify current rates. The slab table lives in a single clearly-labelled, dated config array at the top of this page's script (TAX_SLABS). Rebates, surcharge on very high incomes, and deduction eligibility are not modelled here — treat this as an estimate, not tax advice.

FAQ
What are the New Regime slabs for FY2025-26?
As configured here: up to ₹4 lakh nil, ₹4–8 lakh 5%, ₹8–12 lakh 10%, ₹12–16 lakh 15%, ₹16–20 lakh 20%, ₹20–24 lakh 25%, and above ₹24 lakh 30%, plus 4% cess. These are stored in the editable TAX_SLABS array — always verify against the current Finance Act before filing.
Why does my effective rate look lower than my slab?
Because the slab system is progressive. Your highest slab rate applies only to the income inside that slab, so your effective (average) rate across the whole income is always lower than your top marginal slab rate.
Does this include surcharge and rebate?
No. This estimator computes slab-wise tax plus 4% cess only. Section 87A rebate, surcharge on high incomes and deduction limits are not modelled — consult a tax professional for your filing.
