The graduated slab rates apply: nil up to Rs. 4 lakh, then 5%, 10%, 15%, 20%, 25% in successive slabs.
Example 2: Priya runs a consulting business with receipts of Rs. 60 lakh (90% digital). Under Section 44ADA, she can declare 50% as income = Rs. 30 lakh. She opts for the old regime to claim Chapter VI-A deductions including Rs. 1.5 lakh (80C), Rs. 50,000 (NPS 80CCD(1B)), and Rs. 25,000 (80D).
