How to Choose Between Regimes
Selecting the optimal tax regime depends on your income level and eligible deductions. Here’s a decision framework:
- Calculate Taxable Income: Determine your gross income minus standard deduction (₹50,000).
- List Eligible Deductions: Compile all deductions under Sections 80C, 80D, 80G, HRA, etc.
- Compare Tax Liability:
- If deductions exceed ₹3.75 lakh, the old regime is typically better
- For income below ₹7 lakh with minimal deductions, new regime offers full rebate
- For income between ₹7-15 lakh, compare both regimes using our calculator
- Consider Future Plans: If you plan to invest in tax-saving instruments (PPF, NPS, etc.), the old regime may be more beneficial long-term.

Yes, from AY 2024-25 onwards, you can choose between regimes each year when filing your ITR. Previously, salaried individuals could only switch once.
