Permits comprehensive deductions including ₹1.5 Lakhs (80C), ₹25,000-₹50,000 (80D), Section 24(b) housing loan interest up to ₹2 Lakhs, and Rule 2A HRA exemptions, but features steeper tax slabs up to 30%.

Can salaried individuals switch between Old and New Tax Regimes every year?

Yes. Salaried individuals with no business or professional income can switch between the Old and New Tax Regimes every financial year at the time of filing their Income Tax Return (ITR-1 or ITR-2) under Section 139(1). However, individuals with business income can opt out of the new regime only once in a lifetime.

How does the Section 87A rebate differ between the New and Old Regimes?

Under the New Tax Regime, Section 87A provides a full rebate on taxable income up to ₹7,00,000 (meaning zero tax up to ₹7.75 Lakhs gross income for salaried employees). In contrast, the Old Tax Regime limits the Section 87A rebate to a taxable income of ₹5,00,000 (maximum rebate of ₹12,500).

Is the ₹75,000 standard deduction available in the Old Tax Regime as well?

No. The enhanced ₹75,000 standard deduction introduced in Finance Act 2024 applies strictly to the New Tax Regime (Section 115BAC). Under the Old Tax Regime, the standard deduction for salaried individuals remains capped at the earlier level of ₹50,000.
