- You have a home loan with interest payments above ₹1.5 lakh/year
- You pay health insurance premiums for yourself and parents
- Your total deductions exceed ₹3.75 lakh per year
6. When to Choose New Regime
- Your salary is below ₹12.75 lakh (zero tax with standard deduction)
- You don't invest in 80C instruments or pay rent
- You prefer simplicity — fewer declarations and paperwork
- Your employer doesn't offer HRA or you live in your own home
- Your salary is above ₹15 lakh and deductions are limited
⚡ Quick Verdict by Salary Range
- Below ₹7.75 LPA → New Regime (zero tax)
- ₹7.75 – ₹12 LPA → Depends on deductions; calculate both
- ₹12 – ₹15 LPA → Old Regime usually wins if you have HRA + 80C
- Above ₹15 LPA → New Regime often wins; compare case-by-case
7. Can You Switch Regimes Every Year?
Yes — salaried individuals can switch between regimes every financial year when filing their ITR. However, during the financial year itself, you can only declare one regime to your employer for TDS purposes. If you want to switch at ITR time, you'll need to reconcile any excess or short TDS deducted.
Self-employed individuals and business owners have fewer switching opportunities — they can switch to the Old Regime only once from the New Regime.
8. Frequently Asked Questions
Is the New Regime now the default?
Yes. From FY 2024-25 onwards, the New Tax Regime is the default for all taxpayers. If you want to use the Old Regime, you must explicitly opt in by submitting a declaration to your employer or selecting it while filing your ITR.
What is the Section 87A rebate in the New Regime?
Under the New Regime for FY 2026-27, if your total taxable income does not exceed ₹12 lakh, you get a full tax rebate under Section 87A — meaning your tax liability becomes zero. This is a significant benefit for those earning below ₹12.75 lakh (with standard deduction).
Does NPS help in both regimes?
Yes. Employer contributions to NPS under Section 80CCD(2) are deductible under both the Old and New regimes. This is one of the few deductions available in the New Regime and can be an effective tax-saving tool.
