Old vs New Tax Regime: Which Saves You More in 2026?

For years, choosing your income tax regime meant actively opting in to the new one. That has flipped. For FY 2025-26 (the year you file by July 2026), the new regime is the default. If you do nothing, that is the regime you are taxed under. So the real question is no longer “should I switch to the new regime?” It is the opposite: “Do I have enough deductions to be better off opting back into the old one?”

For a lot of salaried people the honest answer is no, and that is fine, because the new regime now makes income up to ₹12.75 lakh effectively tax-free for a salaried earner. But for some (mainly people paying rent with a big House Rent Allowance, or servicing a home loan) the old regime still wins by a wide margin. This post shows exactly where the line sits, with real numbers you can check against your own salary, before the 31 July 2026 filing deadline.

What actually changed, and why the default matters

Two changes from Budget 2025 carry through this filing season and reshape the decision:

• The rebate under Section 87A in the new regime rose to ₹60,000, which means a resident with taxable income up to ₹12 lakh pays zero tax under the new regime (official announcement).
• The standard deduction for salaried taxpayers in the new regime is ₹75,000. Stack it on the rebate and a salaried person earning up to ₹12.75 lakh owes nothing.

Here are the new-regime slabs for FY 2025-26:

A 4% health and education cess applies on top of the tax in both regimes. The catch with the new regime is the trade: those lower rates come with almost no deductions. You lose 80C, HRA, home-loan interest and 80D. You get the rates; you give up the write-offs.

The two regimes, side by side

The old regime keeps every familiar deduction but charges higher rates above ₹10 lakh, with a smaller ₹50,000 standard deduction.

The old-regime slabs are unchanged: nil up to ₹2.5 lakh, 5% to ₹5 lakh, 20% to ₹10 lakh, and 30% above that. Because the 20% band starts so early, the old regime only pulls ahead once your deductions are large enough to drag a big slice of income out of those higher brackets.

A worked example: ₹15 lakh salary

Numbers make the trade-off concrete. Take a salaried earner on ₹15,00,000 a year. Under the new regime, taxable income is ₹14.25 lakh after the ₹75,000 standard deduction, and the tax works out to ₹97,500 including cess. Under the old regime with no deductions claimed, the same salary attracts ₹2,57,400, over ₹1.6 lakh more.

So far the new regime looks unbeatable. The interesting part is what happens as you add old-regime deductions:

Read the last two rows carefully. Even with ₹4 lakh of deductions (a maxed-out 80C of ₹1.5L, full ₹2 lakh of home-loan interest, and ₹25,000 of health-insurance premium under 80D), the old regime still costs more than the new one. You only break even at roughly ₹5.4 lakh of deductions beyond the standard deduction.

That is a high bar. Hitting ₹5.4 lakh usually requires claiming substantial HRA on top of a home loan and a full 80C. That combination is one most single-income, non-home-loan salaried earners simply do not have. The practical takeaway: at this salary, if you are not paying rent with a large HRA component or repaying a home loan, the new regime almost certainly wins. The break-even amount shifts with your salary, so the rule is to run your own figures. The shape of the answer rarely changes.

Lower down the salary scale, there is barely a decision to make. Because the new-regime rebate covers taxable income up to ₹12 lakh, a salaried earner taking home up to ₹12.75 lakh pays no tax at all under the new regime. No deduction in the old regime can beat zero. So if your salary sits below that line, the new regime is almost always the answer, and you can skip the comparison entirely. The maths only gets interesting once you are clearly into the taxable brackets above ₹12.75 lakh.

One deduction does survive into the new regime, and it is worth knowing: the employer’s contribution to the National Pension System under Section 80CCD(2), up to 14% of basic salary. If your employer offers it, that benefit lowers your taxable income even under the new regime. It is the only common write-off that does. On its own it will not swing the old-vs-new decision, yet it is real money most people overlook.

Which one is right for you

You do not need a spreadsheet to get close. Match yourself to the case below.

If you rent and claim a large HRA

House Rent Allowance is the single biggest swing factor, and it is only available in the old regime. If you live in a metro on rent and your HRA exemption runs into lakhs, the old regime is very likely cheaper. Add it to your 80C and 80D and you can clear that break-even. Keep rent receipts and your landlord’s PAN if annual rent crosses ₹1 lakh.

If you have a home loan

Interest on a self-occupied home loan, up to ₹2 lakh a year under Section 24(b), is a large deduction the new regime ignores. A home loan plus a full 80C (your principal repayment already counts toward 80C) often tips the maths toward the old regime on its own. Run both numbers before you assume.

If your only deduction is 80C or EPF

This is where most people overestimate the old regime. A ₹1.5 lakh 80C alone, even when it is fully funded by your EPF contribution and a little ELSS, is nowhere near enough to beat the new regime’s lower rates and bigger rebate. If 80C is your whole deduction story, the new regime almost always wins.

If you are early-career or have few deductions

Young earners, people who have not started investing for tax, and anyone who values not filing investment proofs: the new regime is built for you. Up to ₹12.75 lakh you pay nothing, and there is no paperwork to assemble. Do not lock money into a five-year tax-saver only to chase a deduction that would not have changed your regime anyway. (If you are weighing where idle money should sit instead, that is a separate decision from your tax regime; see how a savings account quietly loses value to inflation.)

Which ITR form to file, and the deadline

Picking the regime is half the job; you still file on the correct form. For most salaried people it comes down to two:

If you sold stocks or equity mutual funds beyond the ₹1.25 lakh long-term limit, or booked any short-term capital gains, you are on ITR-2 (detailed comparison).

On timing, the key dates for AY 2026-27:

• 31 July 2026, the due date for ITR-1 and ITR-2 (salaried, non-audit).
• 31 December 2026, the last date for a belated or revised return, with a late fee of ₹5,000 (₹1,000 if your total income is below ₹5 lakh) and lost ability to carry forward certain losses (full calendar).

One thing in your favour: a salaried person with no business income can choose afresh every year. Picking the old regime this time does not bind you next time, so revisit the comparison annually as your rent, loan and investments change.

How to decide and file this week

You can settle this in an afternoon:

1. Gather your numbers. Your Form 16 from your employer and the Annual Information Statement (AIS) on the e-filing portal give you salary, TDS and reported income.
2. Total your real old-regime deductions. Add HRA exemption, 80C (including EPF and any ELSS — see how Section 80C works), 80D health premium, and home-loan interest. Be honest; only count what you can document.
3. Run both regimes. Use the official income tax department’s online calculator, or any reputable tax-filing site, and enter the same income under each regime.
4. Pick the lower number, then the right form. Choose the regime, then confirm whether you are on ITR-1 or ITR-2 using the table above.
5. File before 31 July 2026. Filing early avoids the last-week portal rush and leaves room to fix mistakes with a revised return.
6. Save your proofs. Keep rent receipts, investment statements and Form 16 for at least a few years in case of a query.

Frequently Asked Questions

Can I switch between regimes every year? If you are salaried with no business or professional income, yes. You choose freshly at the time of filing each year. Taxpayers with business income face tighter rules and a separate form to switch.

Is the new regime always the better choice now? No. It is the better default for people with few deductions, which is a large share of salaried earners. But anyone with a substantial HRA claim or a home loan should still run the old-regime numbers; for them it can save well over a lakh a year.

Do I still need 80C investments if I am on the new regime? Not for tax purposes — they will not reduce your new-regime liability. But your EPF still builds retirement savings and term insurance still protects your family. Keep those for what they do, not for a deduction you are no longer claiming.

Is ₹12.75 lakh really fully tax-free? For a salaried earner, yes: the ₹75,000 standard deduction brings ₹12.75 lakh down to ₹12 lakh of taxable income, which the 87A rebate wipes out. Just above ₹12 lakh, “marginal relief” softens the jump so you never pay more extra tax than the income that crosses the line.

What if I told my employer the wrong regime for TDS? The regime you declared to your employer at the start of the year only decides how much tax they deduct each month — it does not lock your final choice. When you file, you can still pick the other regime, and any excess TDS comes back as a refund. So a mismatch is not a problem; the return is where the real decision is made.

What if I miss 31 July 2026? You can still file a belated return up to 31 December 2026, but you pay a late fee and lose the right to carry forward some losses. If you owe tax, interest also accrues from the original due date — so filing on time is cheaper than it looks.

Choosing a regime has little to do with which one is “better” in the abstract. What matters is which one is lower for your salary and your deductions. Run the two numbers once, file on the right form before the end of July, and you have settled it for the year.
