How this calculator works

Salary is reduced by exempt allowances (old regime) and the standard deduction — ₹50,000 old, ₹75,000 new. Rental income gets the 30% standard deduction under Section 24(a), and let-out home loan interest is deducted (loss set-off up to ₹2L in the old regime only). Chapter VI-A deductions (80C capped at ₹1.5L, NPS at ₹50K, 80TTA at ₹10K / ₹50K for seniors, self-occupied interest at ₹2L) apply in the old regime; employer NPS under 80CCD(2) applies in both. Digital asset income is taxed at a flat 30% with no rebate.

FAQ

Which regime should I pick?

The new regime usually wins unless your combined deductions (80C + 80D + HRA + home loan interest) are large. Fill in your actual numbers above — the greener regime is highlighted automatically.

Is the rebate really zero tax up to ₹12.75L?

For salaried taxpayers in the new regime, yes: ₹12.75L salary − ₹75,000 standard deduction = ₹12L taxable, fully covered by the 87A rebate. Special-rate income like crypto is not eligible.
