Tax Regime Calculator: New vs Old (FY 2026-27)

Tax regime calculator: worked examples for FY 2026-27

The same salaries run through this calculator’s engine, new regime against old. In the new regime nothing beyond the ₹75,000 standard deduction is claimed; the old-regime columns add 80C and 80D at their caps (₹1,75,000 together), then ₹2,00,000 of home-loan interest on top.

On ₹15,00,000 the new regime comes to ₹97,500. The old regime is ₹2,57,400 with nothing claimed, ₹2,02,800 with 80C and 80D, and ₹1,40,400 with home-loan interest as well — still above the new regime. Up to ₹12,00,000 of gross salary the new regime is nil, because taxable income stays within the rebate after the standard deduction.

Income tax on ₹5 lakh to ₹30 lakh salary

Every salary that has its own page, worked through this calculator’s engine with nothing claimed beyond each regime’s standard deduction: new-regime tax for the year and per month, old-regime tax, and the old-regime deductions (beyond the ₹50,000 standard deduction, rounded up to the next ₹1,000) at which the old regime draws level. Each row links to the page that works that salary through both regimes slab by slab.

Which regime is lower for tax saving: the deductions it takes

The old regime only comes out lower once its deductions are large enough to overcome the new regime’s lower rates and larger standard deduction. The table gives that amount: the total of 80C, 80D, home-loan interest, HRA exemption and any other old-regime deduction, beyond the ₹50,000 standard deduction, at which the old regime draws level.

On ₹15,00,000 it is ₹5,44,000 and on ₹20,00,000 it is ₹7,09,000. At ₹10,00,000 and ₹12,00,000 the new regime is nil, so the old regime needs ₹4,50,000 and ₹6,50,000 of deductions to reach its own rebate. From ₹25,00,000 the figure stops rising, at ₹8,00,000, because both regimes tax the last rupee at 30%. Whether your own claims reach the figure is what the calculator above checks.

Old vs new regime — FY 2026-27

The new regime has wider slabs and lower rates but allows almost no deductions. The old regime has narrower slabs and higher rates but permits 80C, 80D, HRA exemption and home-loan interest. Which one taxes you less depends entirely on how much you can actually deduct.

For FY 2026-27 the new regime is taxed at nil up to ₹4,00,000, 5% to ₹8,00,000, 10% to ₹12,00,000, 15% to ₹16,00,000, 20% to ₹20,00,000, 25% to ₹24,00,000 and 30% above that. The standard deduction is ₹75,000, and the Section 87A rebate makes tax nil where taxable income is ₹12,00,000 or less, with marginal relief just above it.

The old regime is nil to ₹2,50,000, 5% to ₹5,00,000, 20% to ₹10,00,000 and 30% above, with a ₹50,000 standard deduction and an 87A rebate of up to ₹12,500 where taxable income is ₹5,00,000 or less.

The deduction break-even

Because the new regime gives a larger standard deduction and lower rates, the old regime only wins once your deductions are big enough to overcome that gap. The main levers are 80C (capped at ₹1,50,000), 80D health premiums (₹25,000 for self and family below 60), home-loan interest on a self-occupied property (capped at ₹2,00,000) and HRA exemption.

The break-even table above gives the level at a few salaries; your own position depends on what you can actually claim. Enter your actual deductions above and the calculator computes both regimes on your own numbers and reports the difference in rupees.

What this calculator does not model

Surcharge on income above ₹50,00,000 is not included, so very high incomes are understated in both regimes. Capital gains, business or professional income, more than one house property, and the senior-citizen (60+ and 80+) slabs are also outside scope.

The 4% Health and Education Cess is applied in both regimes after rebate and marginal relief. HRA exemption is taken as you enter it — use the HRA calculator to work out your eligible amount first.
