1. Why the confusion arise
Question A19(b) is badly worded. It assumes that if you have “business/profession” income, the only reason you’d be answering this block is because you want to opt out of the new regime.
But in reality, many taxpayers (like you) simply want to continue under the new regime — and the form still forces them to go through these screens.
So, on the surface, it looks like you’re “choosing to opt out” even though you are not.

2. The correct path (when continuing in New Regime with business income)
Step 1: Answer A19(b) as if you fall under “by filing 10-IEA” (Answer Set A), even though you don’t actually want to file Form 10-IEA.
Step 2: When the system then asks:
“Have you exercised option u/s 115BAC(6) in Form 10-IEA in AY 2024-25?” → Select “No”
“Do you wish to opt out of New Tax Regime for current assessment year?” → Select “No”
Net effect: You remain in the New Regime, and the return will compute accordingly.

3. Why this is safe
The controlling answer is b1 (“Do you wish to opt out of New Tax Regime for current AY?”). When you select “No”, you are clearly telling the system (and CPC processing) that you are not opting out.
The earlier forced choices are just routing logic in the utility — they don’t override your final choice.
The computation of tax liability in your ITR is the proof. If the return shows calculation under the new regime slab rates, then your intent is implemented correctly.

4. CBDT position
CBDT notified that from AY 2024-25, New Regime is the default (unless you opt out).
Opting out (especially with business/profession income) requires filing Form 10-IEA.
Since you are not opting out, Form 10-IEA is irrelevant for you.
The ITR form just happens to pull you through those questions anyway.

Conclusion: Your CA’s guidance is correct.
This is a quirk of ITR-3’s wording and flow, but as long as you select “No” in b1 (opt out?), you are safely continuing in the New
Tax Regime, and CPC will process your return correctly.
