Yes, you can change your tax regime every year, but only if your income does not include earnings from a business or profession. Salaried taxpayers and others with non-business income (interest, rent, capital gains, and similar sources) make the choice fresh in every Income Tax Return, so the old regime one year and the new regime the next is entirely permitted. Anyone with business or professional income is treated differently: the new regime is the default, and once you opt out and later switch back, you cannot return to the old regime again.
Salaried and Non-Business Taxpayers: A Fresh Choice Every Year
If your income comes from salary, interest, rent, capital gains, or any source other than a business or profession, you have full annual flexibility. The Ministry of Finance has confirmed this directly: eligible persons without business income can choose the new regime in one financial year and the old regime in another, and vice versa.1Ministry of Finance. Clarification Regarding Applicability of New Tax Regime and Old Tax Regime
You exercise the choice inside the ITR itself, filed on or before the due date under Section 139(1). No separate form is required. You select “Old Regime” or “New Regime” in the return, and the portal computes your liability under the slabs and deductions that apply.2Income Tax Department. FAQs on New Tax vs Old Tax Regime
During the year, you can tell your employer which regime to use for TDS calculations. That intimation is not binding. Your final regime is whatever you pick in the ITR at filing time, and it can differ from what your employer applied. Excess TDS is refunded; any shortfall is collected.
Because the choice resets each year, last year’s decision does not lock you in. Deduction profiles change: a home loan gets paid off, rent payments stop, a policy matures, a large premium falls in one year and not the next. Run the comparison every filing season instead of assuming the previous year’s winner is still right.
Business and Professional Income: One Switch, Then You’re Locked In
The rules tighten sharply if you earn income from a business or profession, whether as a sole proprietor, partner, or freelancer. The new regime under Section 115BAC is your default. You can opt out to the old regime by filing Form 10-IEA. But once you later switch back to the new regime, you permanently lose the ability to choose the old regime in any future year.2Income Tax Department. FAQs on New Tax vs Old Tax Regime
Think of it as a one-way door. You start in the new regime. You can walk out to the old regime. You can walk back into the new regime. That second walk-through locks the door behind you. This is where business taxpayers get tripped up: assuming the annual flexibility that salaried filers enjoy applies to them, opting out casually, switching back, and then discovering the old regime is no longer available.
Form 10-IEA itself must be filed on or before the Section 139(1) due date. Filing even a day late makes the form invalid, and the department will assess you under the new regime for that year. File the form before you file the ITR, because the return asks for the acknowledgment number and filing date of Form 10-IEA.3Income Tax Department.

The Deadline That Decides Whether Your Choice Counts
Your regime selection is only respected if you file the return on or before the due date under Section 139(1). For most individual taxpayers, that date is July 31 of the assessment year. Where accounts require auditing, the deadline extends to October 31.5Income Tax Department. Income-Tax Act 1961 – Section 139(1)
Miss that deadline and the choice is gone. A belated return filed under Section 139(4) is processed under the default new regime regardless of your preference. Even if a business taxpayer had filed Form 10-IEA in time, a belated ITR overrides that opt-out. The July 31 date is not just about avoiding late fees. It is the hard cutoff for exercising your regime selection at all.
How to Decide Which Regime to Pick This Year
The new regime carries lower slab rates but strips out most deductions and exemptions. Chapter VI-A deductions are not available under the new regime, except for employer NPS contributions under Section 80CCD(2), income from the Agniveer fund under Section 80CCH, and new employment deductions under Section 80JJAA.2Income Tax Department. FAQs on New Tax vs Old Tax Regime HRA exemption under Section 10(13A), home loan interest on a self-occupied property, LTA, and the popular Section 80C and 80D deductions are only available in the old regime.
Salaried filers do still get the ₹75,000 standard deduction under the new regime, and employer NPS contributions remain deductible up to 14% of basic salary. A 4% health and education cess applies on top of the tax under both regimes.
A working rule of thumb: if your combined eligible deductions under 80C, 80D, HRA, home loan interest, and other exemptions run to roughly ₹3,00,000 to ₹4,00,000 or more, the old regime likely produces a smaller bill. Below that, the new regime’s lower slab rates typically win even without deductions. The crossover shifts with income level, so the safer step is to plug your actual figures into the Income Tax Department’s comparison calculator on the e-filing portal and see the two liabilities side by side.6Income Tax Department.

Recording the Choice on the Portal
For salaried and non-business filers, the whole process happens inside the return. Log in at incometax.gov.in, start the ITR for the relevant assessment year, and select “Old Regime” or “New Regime” when prompted. The portal recalculates your liability under the applicable slabs and deductions. Nothing else is needed.
For business and professional income, file Form 10-IEA first through the e-filing portal. It generates an acknowledgment number you enter into the ITR. Because of the one-switch restriction, treat the decision to file Form 10-IEA as one you may not be able to reverse cleanly: opting out now, switching back later, and hoping to come back to the old regime a third time will not work.
After filing, download the ITR-V acknowledgment from the portal and keep it. The ITR-V records which regime was applied and the tax computation for that assessment year, which matters if a question comes up later about which regime governed a particular return.7Income Tax Department.
