Ans: As per Section 44AD, individuals will calculate income by keeping 8% of the turnover (or 6% for digital payments and receipts). For example, Riya has a bookstore with Rs. 72 lakhs turnover for the preceding year.  Since she wants to opt for presumptive taxation, her income will be calculated at 8% of Rs. 72 lakhs (8÷100×72,00,000 = Rs. 5,76,000). Yearly presumptive tax will depend on the slab of Rs. 5,76,000.
