Old vs New Tax Regime India FY 2026-27
Quick Summary
The Old Tax Regime has higher slab rates (5%/20%/30%) but allows deductions under 80C, HRA, 80D, and home loan interest. The New Regime (default) has wider slabs (5%/10%/15%/20%/25%/30%) with no major deductions except the ₹75,000 standard deduction, and provides zero tax for taxable income up to ₹12 lakh via the Section 87A rebate (about ₹12.75 lakh for a salaried person).
The Break-Even Deduction Amount
Since the new regime's slabs were widened and the rebate lifted to ₹12 lakh, the break-even deduction amount is now high. As an illustration, at a gross salary of ₹15 lakh the old regime only starts to win when deductions beyond the standard deduction reach roughly ₹5 lakh. The break-even moves with income, so use ToolsDock's Income Tax Calculator to find the exact answer for your figures.
Who Should Choose the New Regime
The new regime is almost always better if: you are a fresh graduate or early-career professional not yet investing heavily in 80C instruments; you do not pay rent (no HRA); you do not have a home loan; your salary is up to ₹12.75 lakh (zero tax after the standard deduction and the 87A rebate); or you prefer simplicity without tracking deductions.
Who Should Choose the Old Regime
The old regime remains beneficial if: you max out 80C (₹1.5L in PPF, ELSS, or LIC) + pay rent (HRA) + pay medical insurance (80D) + have a home loan with interest deduction. If these combined deductions are very large (for many mid-income salaried taxpayers, ₹5 lakh or more), the old regime's higher rates can be offset by the deduction benefit. Run both regimes in the calculator before deciding.
Worked Example: ₹10 Lakh and ₹15 Lakh Salaries
At a ₹10 lakh gross salary, the new regime gives zero tax (taxable ₹9.25 lakh is under the ₹12 lakh rebate limit), while the old regime with ₹1.5 lakh in 80C costs about ₹75,400 including cess. At ₹15 lakh, the new regime costs about ₹97,500, while the old regime with ₹3.5 lakh of deductions costs about ₹1.48 lakh. Only very large deduction totals tip the balance back to the old regime.
Do Not Buy Tax Savers Just for the Deduction
Locking money into products only to claim 80C makes little sense when the new regime already gives a lower tax bill. Choose investments for your goals and returns first, and treat any deduction as a bonus. A SIP in a suitable fund can serve long-term goals whichever regime you pick.
How to Decide Each Year
Total your likely deductions at the start of the year, run both regimes in the Income Tax Calculator, and tell your employer your choice so TDS is deducted correctly. You can switch each year if you only have salary income, and you can still correct the choice when you file your return. Slabs and rebates can change with each Budget, so confirm the current rules on the income tax portal.
