Old vs New Tax Regime: Which One Actually Saves You Money

There are two income tax regimes in India, and the government keeps making the new one more attractive. The old regime has higher headline rates but lets you subtract a long list of deductions before those rates apply. The new regime has lower rates and takes almost all of that away.

Which one costs you less is not a matter of opinion. It is one subtraction, done twice.

The two rate tables

The new regime's slabs are wider and start lower. The old regime's are the ones that have been broadly stable for years:

Both then add a 4% health and education cess on the tax computed, and a surcharge above ₹50 lakh. Slab boundaries and the rebate threshold move in most Budgets, so check the current year's figures before relying on any specific number here: the method is what stays constant.

The break-even deduction

Here is the useful way to think about it. The new regime hands you a rate cut. The old regime hands you deductions. The question is whether your deductions are worth more than the rate cut.

For most salaried people in the ₹10 to ₹15 lakh band, the crossover sits somewhere between ₹3 lakh and ₹4.5 lakh of total deductions. Below that, the new regime wins. Above it, the old one does.

That sounds like a lot until you count what a typical person already has:

• Standard deduction, automatic for salaried taxpayers
• EPF contribution, which is already coming out of your salary and counts toward 80C
• Life insurance premiums, PPF, ELSS or children's tuition fees, also 80C, capped at ₹1.5 lakh in total
• Health insurance under 80D, ₹25,000 for yourself and family, ₹50,000 more if you pay for senior-citizen parents
• HRA, if you pay rent and your salary has an HRA component. This is frequently the largest single item
• Home loan interest on a self-occupied property under Section 24(b), up to ₹2 lakh

Someone with a home loan and rent paid in a metro can clear ₹5 lakh of deductions without doing anything unusual. Someone renting modestly with no home loan and only their EPF often cannot reach ₹3 lakh, and the new regime is simply cheaper for them.

Two people, same salary, different answers

Take two people earning ₹14,00,000 a year.

Person A lives in their own flat, has a home loan, pays ₹1.5 lakh into 80C instruments and ₹25,000 for health insurance. Their deductions: ₹1,50,000 (80C) + ₹25,000 (80D) + ₹2,00,000 (home loan interest) + the standard deduction. That is well over ₹4 lakh. Their taxable income under the old regime falls to around ₹9.2 lakh, and the old regime wins comfortably.

Person B rents a small place outside a metro with no HRA component in their salary, has no home loan, and whose only 80C is EPF at about ₹60,000. Their deductions barely exceed ₹1.1 lakh. Under the old regime their taxable income stays near ₹12.9 lakh and is taxed at 30% at the margin. The new regime's lower rates save them money outright.

Same income, opposite answers. This is why a general rule of thumb is useless and why the only reliable approach is to compute both.

Four things people get wrong

Comparing gross salary instead of taxable income. The regimes differ in what you are allowed to subtract before the rates apply. Comparing the rate tables alone tells you almost nothing.

Forgetting that EPF is already a deduction. Your provident fund contribution counts toward 80C whether you thought about it or not. People routinely under-count their deductions by ₹50,000 or more because of this.

Buying an insurance policy purely to save tax. A deduction returns your marginal rate, so at 30% a ₹1 lakh investment saves ₹30,000 of tax. That is not a return, it is a discount on money you locked away. If the underlying product is poor, the tax break rarely rescues it.

Assuming the choice is permanent. For salaried taxpayers it is not. If your circumstances change, a home loan ends or a rent agreement starts, the better regime can flip. Recompute annually.

The two-minute version

1. Add up every deduction you can actually claim this year. Be honest: only what you will really invest and really pay.
2. Compute tax under the old regime on income minus those deductions.
3. Compute tax under the new regime on income minus only the standard deduction.
4. Pick the smaller number.

Our Income Tax Calculator does steps 2 and 3 side by side from one set of inputs, so you only need step 1. If you are unsure how much of your rent qualifies, the HRA Calculator works out the exempt portion, which is the item most likely to tip the decision toward the old regime.

One last note: this is general information about how the two systems compare, not personal tax advice. If your situation involves capital gains, business income, foreign assets or anything else out of the ordinary, the crossover moves and a chartered accountant is worth the fee.
