Basics: What “new vs old regime” actually means
India’s income tax gives you two broad ways to compute tax: Old regime (deductions/exemptions allowed) and New regime (simplified, usually fewer deductions).
The “best” option is not moral or philosophical. It’s just whichever produces lower tax after considering your deductions and exemptions.
New regime usually wins when…
- You don’t claim many deductions/exemptions
- Your salary structure is simple (low HRA / fewer components)
- You prefer fewer documents & less compliance headache
Old regime can win when…
- You max out 80C/80D and other deductions
- You have meaningful HRA benefits
- Home-loan interest deductions matter in your case

Important notes
- This calculator is a simplified estimator (does not handle surcharge complexities and special incomes).
- Rebate thresholds and rules can change by Budget and can have marginal relief; always verify on official sources for your exact filing.
- You can tweak assumptions below (standard deduction, cess, deductions) to match your reality.
Instant comparison calculator
Enter your numbers. We compute approximate tax under both regimes and show the difference.
Include 80C/80D/HRA/home-loan etc. (your estimate).
If you have any deductions allowed in the selected year, enter them.
Mini sanity-check (very useful)
If your Old regime deductions are large enough, old wins. If deductions are low, new often wins. The break-even depends on your income level and slabs.
Decision rules (fast, practical)
Use these rules like a compass—then confirm with the calculator.
Pick New Regime if…
- You don’t claim big deductions
- Your investment/insurance tax-saving is limited
- You want simpler compliance & fewer proofs
- You’re okay with fewer “structure hacks”
Pick Old Regime if…
- You have large deductions (80C/80D/etc.)
- HRA benefit is significant
- Home loan interest and exemptions matter
- You can document & claim properly
The “one-liner”
If your deductions are small, new regime usually wins on rates. If deductions are big, old regime can win despite higher rates.
