ITR-4 Business Filers: 1 Regime Switch That Costs You

If you file ITR-4 for business income, switching between old and new tax regimes has strict rules. One wrong move can lock you out of deductions like 80C forever. Here's what you must know before filing this season.

Here's what happened: ITR-4 (Sugam) is used by individuals and HUFs with business or professional income up to ₹50 lakh under presumptive taxation schemes like Section 44AD or 44ADA.. Business income filers get only ONE lifetime chance to opt out of the new tax regime and switch back to the old regime — after that, the old regime is permanently closed to them.. Salaried individuals can switch tax regimes every year freely, but ITR-4 business income filers face a much stricter one-time-only reversal rule under current income tax law..

What you should do: Compare your actual deductions (80C, HRA, home loan interest, 80D) against the new regime's lower slab rates BEFORE filing — use a tax calculator with real numbers, not guesses.. File Form 10-IEA before the ITR deadline if you want to opt out of the new tax regime for AY 2025-26; missing this form means you are automatically taxed under the new regime.. Avoid switching regimes back and forth without a clear plan — consult a CA or tax advisor if your annual business income fluctuates, since one irreversible switch can cost you lakhs over a career..

If you chose the old regime last year as an ITR-4 filer and want to stay in it this year, you must still file Form 10-IEA every year to reconfirm — silence does NOT mean continuity.
