Frequently Asked Questions

Yes! For salaried taxpayers, the ₹75,000 standard deduction reduces ₹12,75,000 gross salary to ₹12,00,000 taxable income. Under Section 87A (Section 156 of the Income Tax Act 2025), normal slab tax up to ₹60,000 is 100% rebated at or below ₹12,00,000 taxable income, making total tax ₹0.

Marginal relief protects you! At ₹12.90L salary (₹12.15L taxable income), your tax before cess cannot exceed the ₹15,000 income above ₹12,00,000. So instead of paying ₹62,250 slab tax, you pay only ₹15,000 + 4% cess = ₹15,600.

At ₹15 lakh salary, you need over ₹5.25 lakh in total deductions (HRA + 80C + 80D + Home Loan Interest) for the Old Regime to tie with the New Regime. At ₹20 lakh+, the breakeven point is roughly ₹7.12 lakh to ₹8.0 lakh of deductions.

No. Special-rate income such as Section 111A STCG (20%) and Section 112A LTCG (12.5% above ₹1.25 lakh exemption) does not qualify for the Section 87A / Section 156 rebate and is taxed separately.
