Frequently Asked Questions (FAQs)
What is the break-even deduction point between Old and New Tax Regime in FY 2026-27?
For a ₹15 Lakh salary, your total eligible deductions under Old Regime (80C, 80D, HRA, home loan interest) must exceed ₹4,00,000 for the Old Regime to result in lower tax than the New Regime. For a ₹20 Lakh salary, deductions must cross ₹4,50,000.
Is salary up to ₹12.75 Lakhs zero tax in New Regime?
Yes. Under the New Tax Regime for FY 2026-27, a gross salary of ₹12,75,000 attracts zero income tax. The ₹75,000 standard deduction brings taxable income to ₹12,00,000, which gets fully rebated under Section 87A (maximum ₹60,000 rebate).
Can I switch between Old and New Tax Regime every year?
Salaried employees with no business or professional income can switch between the Old and New Tax Regimes every year at the time of filing their ITR. Individuals with business or freelance income (ITR-3/ITR-4) can only switch once in a lifetime.
Do I get HRA and Section 80C benefits in the New Tax Regime?
No. The New Tax Regime does not permit deductions for HRA, Section 80C (PPF, ELSS, LIC), Section 80D (Health Insurance), or Section 24(b) home loan interest. It provides lower baseline tax slab rates and a flat ₹75,000 standard deduction instead.
Relevant Financial Calculators

Every financial year, your company HR asks you to declare your tax regime.
On one side is the Old Tax Regime: higher slab rates, but packed with deductions for house rent (HRA), home loan interest (§24b), life insurance, EPF, and medical premiums (§80D).
On the other side is the New Tax Regime: significantly lower tax slabs, a flat ₹75,000 standard deduction, and zero income tax for gross salaries up to ₹12.75 Lakhs thanks to the Section 87A rebate.
The question is simple: Exactly how much money must you spend on deductions to make the Old Regime beat the New Regime? Here is the exact break-even math.
1. The break-even deduction table across salary tiers
If your total deductions (80C + 80D + HRA + Home Loan Interest) are higher than the break-even number, pick Old Regime. If they are lower, pick New Regime.

Find out if your actual investments and rent receipts beat the New Tax Regime.
Salaries up to ₹12.75 Lakhs: You pay ₹0 tax automatically without locking any cash into lock-in schemes.
Young professionals renting cheap: If you live with parents or pay modest rent, you cannot claim enough HRA to beat the ₹4L+ break-even threshold.
No home loan: Without ₹2 Lakhs of home loan interest deduction under Section 24(b), reaching ₹4.25L deductions is very difficult.
Zero paperwork: No need to submit rent receipts, landlord PAN, or insurance premium proofs to HR every January.
When the Old Tax Regime Still Wins
Paying high metro rent: If you claim ₹2.5L+ in HRA exemptions plus ₹1.5L under 80C, your total deductions cross ₹4L easily.
Active home loan borrowers: Claiming ₹2 Lakhs under Section 24(b) plus ₹1.5L under 80C plus ₹50k under 80D puts your deductions at ₹4.5L+, making Old Regime save you ₹30,000 to ₹60,000 extra.

Check how much HRA you can legitimately claim based on rent receipts and metro city rules.
