To make the Old Regime advantageous, your total deductions (HRA + 80C including your own EPF + 80D + 24b Home Loan Interest + NPS + professional tax, not counting the ₹50,000 standard deduction) must strictly exceed the break-even amount below. CTC is split as on our calculators: basic 50%, with employer PF and gratuity not taxed.

4. How to Choose Your Regime in 4 Steps
Sum up your total eligible exemptions
Calculate your actual eligible HRA (§10(13A)), Home Loan Interest (§24b up to ₹2L), Section 80C (up to ₹1.5L, including your own EPF), Section 80D (health insurance up to ₹50k-₹1L), 80CCD(1B) NPS and professional tax.
Leave out the standard deduction
The break-even figures already allow for the ₹50,000 Old Regime standard deduction, so compare your total without it.
Compare against our Break-Even Table
If your total deduction is less than the break-even number for your salary level, the New Regime provides an immediate guaranteed higher take-home pay.
Verify employer NPS contribution
Check if your company offers Section 80CCD(2) employer NPS. This deduction is valid in both regimes: up to 14% of basic + DA in the New Regime, and 10% in the Old Regime for a non-government employer (14% for government).

Who should choose the Old Tax Regime in FY 2026-27?
Individuals paying high house rent (claiming large HRA), servicing heavy home loans (₹2 Lakh interest deduction), and exhausting Section 80C and 80D deductions, when the total, beyond the ₹50,000 standard deduction, clears the break-even for their pay.
