3. Presumptive Taxation Under Section 44AD for Port Blair Businesses
Small traders and manufacturers in Port Blair with turnover up to ₹2 crore can opt for Section 44AD presumptive taxation — declaring 8% of gross turnover as income (6% for fully digital receipts) without maintaining detailed books. This is ideal for small businesses in Port Blair's Tourism and hospitality sector that want to minimise compliance burden.
Section 44ADA for professionals: Doctors, lawyers, engineers, architects, and consultants in Port Blair with gross receipts up to ₹75 lakh can declare 50% as presumptive income under 44ADA.
