Old regime or new regime — which one leaves you better off?
The new tax regime has lower slab rates and almost no deductions; the old regime has higher rates and lets you claim 80C, 80D, HRA and home loan interest. Which one costs you less is arithmetic, not preference, and the answer flips depending on how much you actually claim — as a rough line, someone with a home loan and full 80C is usually better off in the old regime, and someone with few deductions is better off in the new one. You may switch each year if you have no business income.

Why some of those rows matter
Section 80C — PF, ELSS, insurance, tuition. For most salaried people PF alone fills a large part of 80C, so this is a deduction you are already earning whether or not you claim it.
Home loan interest, self-occupied. This single deduction is what decides the answer for most people with a home loan.
Switching between years. With business income you may switch out of the new regime once, and back once. After that the choice is fixed.
The recommendation
Who should pick what
Straight answers by situation, including where the answer flips.
If
You have a home loan on a self-occupied house and full 80C
Old regime
₹2,00,000 of interest plus ₹1,50,000 of 80C plus HRA is deduction the new regime cannot match, and it usually outweighs the rate difference by a wide margin.
If
You rent, have no home loan, and 80C is only your PF
New regime
The higher exemption and the ₹75,000 standard deduction beat a partly-used 80C, and you avoid buying financial products you did not want in order to fill it.
If
You are early in your career with income under ₹8 lakh
New regime
The rebate under section 87A takes the liability to nil in the new regime at income levels where the old regime still charges something.
If
You pay significant rent in a metro and claim HRA
Old regime, usually — but compute it
HRA in a metro can be a very large exemption, and it is the one case where the answer is genuinely close enough that it has to be worked out rather than assumed.
The decision is arithmetic, and it changes every year
There is no permanently correct answer. The slabs move with each Finance Act, and your own deductions move with your life — a home loan starts, a child's tuition ends, an insurance premium changes. A choice made three years ago on that year's numbers is not evidence about this year.
The correct method is dull and reliable: compute your liability under both regimes on your actual figures for the year, and pick the lower one. That is a ten-minute exercise with the right inputs, and it is what we do on every salaried return we file.
The break-even is a range, not a number
People look for a single income above which the old regime wins. There is no such number, because the answer depends on deductions rather than income. What exists is a break-even in total deductions: broadly, if your deductions under the old regime come to more than roughly ₹3,50,000 to ₹4,00,000, the old regime tends to win; below that the new one does.
That range is a guide for whether it is worth computing, not a substitute for computing. Two people on identical salaries with different housing arrangements land on different sides of it.
What switching actually costs
A salaried person with no business income may choose afresh every year, at the time of filing, regardless of what they told their employer. The declaration made to payroll in April affects how much TDS is deducted, not what you may claim in the return.
Business and professional income is different. Once you opt out of the new regime you may return to it only once, and after that the choice is locked. That makes the decision worth taking properly the first time rather than annually.
The trap in the old regime
The old regime rewards deductions, and that creates a pull towards buying financial products in March purely to fill 80C. An insurance policy bought to save ₹30,000 of tax, which locks up ₹1,50,000 a year for fifteen years at a poor return, is not a saving.
Claim what you already have. If the old regime only wins because of a product you would not otherwise buy, the new regime is the better answer.
How people get this wrong
- Choosing once and never recomputing, when the slabs and your own deductions both move
- Assuming the regime declared to payroll in April binds the return — it does not, for a salaried filer
- Buying an insurance or ELSS product in March purely to justify the old regime
- Forgetting that the new regime is the default, so saying nothing means choosing it
- For business income, opting out casually and discovering the choice is then locked
