Income tax is computed by applying the FY2025-26 slab rates progressively to taxable income (after standard deduction), then applying the Section 87A rebate with marginal relief near the rebate threshold, plus surcharge and cess where applicable.
It depends on how many deductions and exemptions you claim. Use the Old vs New Tax Regime Calculator to compare your actual tax liability under both.
Under the new regime, income up to ₹12 lakh (₹12.75 lakh with the standard deduction for salaried taxpayers) is effectively tax-free after the Section 87A rebate, with marginal relief at the threshold.
Marginal relief caps your tax at just the amount your income exceeds the rebate threshold, so a small increase in income never results in a disproportionately larger tax bill.
No — this is an estimation tool only, to help you plan. Filing your actual return should account for your complete financial situation and any changes announced after this calculator was last updated.
