What is the Section 87A rebate in the new regime?+

Which regime should I choose — old or new?+
If your total deductions under the old regime exceed roughly ₹3.75 lakh, the old regime often wins. For salaried employees with few deductions, the new regime with its ₹75,000 standard deduction and enhanced 87A rebate usually saves more tax.
