Business Income? You Can't Switch Tax Regimes Yearly

If you earn business or freelance income, you cannot freely switch between old and new tax regimes each year. Filing Form 10-IEA is mandatory to opt out of the new regime, and re-entering the old regime after switching back is nearly impossible.

Here's what happened: Taxpayers with business or professional income filing ITR-3 or ITR-4 cannot switch tax regimes every year — unlike salaried individuals who can do so annually.. Form 10-IEA must be filed before the ITR deadline to opt out of the new tax regime for AY 2026-27; late submission is not accepted.. Once a business taxpayer switches back to the old regime, they get only one lifetime chance to return to the new regime — after that, the switch is permanent..

What you should do: Calculate your total deductions (80C, HRA, home loan interest, professional expenses) right now — if they exceed ₹3.75 lakh, the old regime likely saves you more tax.. File Form 10-IEA on the Income Tax e-filing portal before your ITR deadline if you want to opt for the old tax regime this year — do not wait until after submitting your ITR.. Check which ITR form applies to you — if you have any freelance, consultancy, or business income, you are in the ITR-3/ITR-4 category and the annual switch rule does NOT apply to you..

Pro tip: Even one rupee of business income in a financial year moves you from ITR-1 to ITR-3/4 — meaning the regime-switch restriction applies to you that year, even if salaried income dominates.
