1₹6 Lakh Income - Zero Tax
With ₹75K standard deduction, taxable income is ₹5.25L. Section 87A rebate makes tax zero up to ₹7L taxable income.

After ₹75K standard deduction, tax calculated on ₹9.25L across slabs: ₹20K (5% of 4L) + ₹22.5K (10% of 2.25L) + cess.

New regime slabs: 0-3L (0%), 3-7L (5%), 7-10L (10%), 10-12L (15%), 12-15L (20%), 15L+ (30%). Standard deduction of ₹75,000 (increased from ₹50,000 in Budget 2024) is available.
Old regime: Higher tax rates but allows deductions (80C, 80D, HRA, LTA, etc.). New regime: Lower rates but minimal deductions (only NPS 80CCD employer contribution). Choose based on total deductions - if >₹3-3.5L, old regime may be better.
Standard deduction is a flat ₹75,000 deduction for salaried individuals (increased in Budget 2024 from ₹50,000). Available in both regimes, no bills or proof required. Automatically reduces taxable income.
Steps: 1) Calculate gross income, 2) Subtract standard deduction, 3) Subtract applicable deductions (old regime), 4) Apply tax slabs to taxable income, 5) Add 4% health and education cess. Tax is calculated progressively - each slab taxed at its rate.
New regime is better if deductions are <₹3-3.5L. Old regime is better if you claim: ₹1.5L (80C) + HRA + ₹50K (80D) + home loan interest + other deductions. Use regime comparison calculator for exact calculation.
Section 87A provides rebate of up to ₹25,000 for taxable income up to ₹7 lakh under new regime. This means effective zero tax up to ₹7L income. In old regime, rebate is ₹12,500 for income up to ₹5L.
Surcharge applies on high incomes: 10% for ₹50L-1Cr, 15% for 1-2Cr, 25% for 2-5Cr, and 37% for >5Cr (capped at 25% for new regime). Surcharge is calculated on tax amount, not income.

Salaried individuals can switch regimes each year by informing employer. If already filed ITR, you can file revised return to change regime before due date. Business income holders cannot switch frequently.
