Which ITR form to be used

If you're self-employed with an income of £2 lakh and significant bank transactions, you'll likely need to use either ITR-3 or ITR-4. ITR-3 is for those with income from business or profession profits, while ITR-4 is suitable for individuals with business income computed under specific sections (44AD, 44ADA, or 44AE) and a total income up to £50 lakhs. The exact form depends on the nature of your income sources.
