The Core Trade-Off Explained
Since FY 2020-21, Indian taxpayers have had to choose between two income tax regimes each financial year. The choice is not permanent — you can switch every year for salaried individuals (though business owners have more restrictions).
The Old Regime offers higher tax slabs but allows a wide array of deductions and exemptions (HRA, LTA, 80C, 80D, etc.) that can significantly reduce your taxable income. The New Regime offers lower tax rates but eliminates almost all deductions. The regime that wins for you depends entirely on how much you invest and claim as deductions.
Tax Slabs Comparison (FY 2025-26)
Old Regime
+ 4% Health & Education Cess on tax payable
New Regime (Default)
+ 4% Cess. Also, full rebate u/s 87A for income up to ₹12 lakh (effective zero tax).
Key Deductions Lost in the New Regime
These are the major deductions available in the Old Regime that are not available in the New Regime:
₹1.5 lakh deduction for PPF, ELSS, LIC, EPF, home loan principal, etc.
₹25,000–₹75,000 deduction for health insurance premiums (self + parents)
Fully or partially exempt House Rent Allowance for salaried in rented accommodation
₹2 lakh deduction on home loan interest for self-occupied property
Leave Travel Allowance for domestic travel (twice in a 4-year block)
₹50,000 flat deduction for salaried individuals (NOW also available in New Regime)
₹10,000–₹50,000 deduction on savings account interest
The Break-Even Point: When Old Regime Wins
The Old Regime is better for you only if your total eligible deductions exceed a certain threshold. Here is the approximate breakeven for different income levels:
| Annual Income | Deductions needed to prefer Old Regime |
|---|---|
| ₹7 lakh | New Regime always wins (zero tax via 87A rebate) |
| ₹10 lakh | Old Regime wins if deductions exceed ~₹1.75 lakh |
| ₹12 lakh | Old Regime wins if deductions exceed ~₹2.5 lakh |
| ₹15 lakh | Old Regime wins if deductions exceed ~₹3.75 lakh |
| ₹20 lakh+ | Old Regime wins if deductions exceed ~₹4.25 lakh |
* These are approximate figures. Exact breakeven depends on your HRA component, rent paid, specific allowances, and other factors. Always calculate both scenarios with actual numbers.
Who Should Choose Which Regime?
New Regime is Best For:
- • Income below ₹7 lakh (zero tax)
- • Those with minimal 80C/80D investments
- • Young earners renting cheap accommodation
- • People who prefer simplicity and lower compliance burden
- • High earners with limited deduction access
Old Regime is Best For:
- • Those maximizing 80C (PPF, ELSS, EPF)
- • People paying significant rent (HRA benefit)
- • Home loan holders (₹2L interest deduction)
- • Those with comprehensive health insurance (80D)
- • Income above ₹15L with significant deductions
The Right Approach
Calculate your tax liability under both regimes with actual numbers before your employer freezes your declaration (usually April). Use the FinCalc Pro tools to estimate your SIP corpus, loan EMIs, and other financial commitments — these directly inform your regime choice. When in doubt, consult a CA, especially if you have business income, capital gains, or foreign assets.
