5. What is the rebate under Section 87A in the New Regime?
Under the New Tax Regime, individuals with taxable income up to ₹7,00,000 can claim rebate under Section 87A,

Yes. Standard deduction of ₹50,000 (Old Regime) and ₹75,000 (New Regime as applicable) is available for salaried individuals.

the income earned above the surcharge threshold.
It protects taxpayers from disproportionately high tax at income levels slightly above surcharge limits.
