Frequently asked questions
Do I need a tax audit with ITR-3?
Only if turnover crosses the section 44AB limit (₹1 crore, or ₹10 crore when cash transactions are within 5%) or gross receipts of a profession exceed ₹50 lakh.
Can I switch from ITR-4 to ITR-3?
Yes, but if you opt out of presumptive taxation under 44AD you generally cannot opt back in for five years.
