Old vs New Tax Regime in India: Which Should You Pick?

Every salaried Indian now faces a yearly choice: file under the old tax regime or the new tax regime. Since FY 2023-24, the new regime is the default, so if you do nothing, that is what applies. But default does not mean best for you. The right pick depends almost entirely on how many deductions you actually claim.

The Fundamental Trade-Off

The two regimes strike opposite bargains:

• The new regime gives you lower tax rates and wider slabs, plus a ₹75,000 standard deduction for FY 2024-25, but scraps almost every exemption (no 80C, no HRA, no home-loan interest on a self-occupied home, and so on).
• The old regime keeps the full menu of deductions but charges higher rates on narrower slabs.

In short: the new regime is simpler and cheaper if you have few deductions; the old regime pays off only if your deductions are large enough to offset its higher rates.

The Slabs (FY 2024-25)

A 4% health and education cess applies on top of the tax in both regimes.

Two Features That Make the New Regime Strong

The ₹75,000 standard deduction. For FY 2024-25 the standard deduction under the new regime was raised to ₹75,000 (the old regime stays at ₹50,000). Every salaried person gets it automatically.

The Section 87A rebate up to ₹7 lakh. Under the new regime, if your taxable income is ₹7 lakh or less, the 87A rebate wipes out your tax entirely. Combined with the ₹75,000 standard deduction, a salary up to about ₹7.75 lakh can end up paying zero tax. The old regime's 87A rebate only extends to ₹5 lakh, so its zero-tax ceiling is lower.

When the Old Regime Still Wins

The old regime rewards people who genuinely use its exemptions. The big ones are:

• Section 80C up to ₹1.5 lakh (PF, PPF, ELSS, life insurance, home-loan principal).
• HRA exemption for those paying rent, often the largest single deduction.
• Home-loan interest up to ₹2 lakh on a self-occupied property (Section 24b).
• 80D health-insurance premiums, 80CCD(1B) NPS, and others.

Stack enough of these and the old regime's higher rates get outweighed. If you pay rent, work out your HRA relief first with the HRA Exemption Calculator, because it often tips the decision.

A Break-Even Rule of Thumb

Here is the shortcut. Add up all the deductions you would claim under the old regime (80C + HRA + home-loan interest + 80D and the rest). Then:

• For higher incomes (around ₹15 lakh and above), you generally need roughly ₹3.75–₹4.3 lakh of total deductions for the old regime to beat the new one.
• If your deductions fall short of that, the new regime almost always costs you less.

It is only a rule of thumb because the exact break-even shifts with your income level. The reliable move is to compute both. The India Take-Home Pay Calculator lets you see the actual tax and net salary so you are not guessing.

How to Decide in Practice

1. List the deductions you actually claim, not the ones you could in theory.
2. If they are modest (say, only a bit of 80C and no rent), pick the new regime and enjoy the simplicity.
3. If you pay significant rent or a home loan and max out 80C, run the old-regime numbers, because it may save you more.
4. Compute both every year; salaried employees can switch regimes annually.

The Takeaway

The new regime is the sensible default for most people with few deductions, thanks to lower slabs, a ₹75,000 standard deduction, and the ₹7 lakh rebate. The old regime is worth it only when your deductions are large. Never assume, calculate: check your rent relief in the HRA Exemption Calculator and your net pay in the India Take-Home Pay Calculator before you lock in a choice.
