Compile Salary, Deductions & Banking Certificates

Phase 2

Tax Regime Selection: Old vs New Regime (Sec 115BAC)

Under current tax provisions, the New Tax Regime (Section 115BAC) is the default regime. Taxpayers must compute their liability under both regimes to make the most cost-effective election.

Parameter New Tax Regime (Default u/s 115BAC) Old Tax Regime
Basic Exemption Limit ₹3,00,000 ₹2,50,000 (₹3,00,000 for Senior Citizens)
Standard Deduction ₹75,000 (for Salaried & Pensioners) ₹50,000
Rebate under Section 87A Full tax rebate up to ₹7,00,000 taxable income (Net zero tax up to ₹7.75L with standard deduction) Full tax rebate up to ₹5,00,000 taxable income
Section 80C Deductions (LIC, PPF, ELSS, Tuition Fee) Not Allowed Allowed up to ₹1,50,000
Health Insurance (Section 80D) Not Allowed Allowed (₹25,000 to ₹1,00,000)
House Rent Allowance (HRA) & LTA Not Allowed Allowed as per calculation rules
Home Loan Interest (Self-occupied u/s 24b) Not Allowed Allowed up to ₹2,00,000
Employer NPS Contribution (Sec 80CCD(2)) Allowed (up to 14% of salary) Allowed (up to 10% / 14%)
CA Decision Rule: If your total deductions (HRA + 80C + 80D + Home Loan Interest) exceed ₹3,75,000, the Old Tax Regime usually results in lower tax. If deductions are below this threshold, the New Tax Regime is substantially more beneficial.
Phase 3
