What Section 44ADA does
Section 44ADA lets a notified professional skip a full set of books. You do not list every laptop bill, software subscription, or train ticket. You declare profit as a fixed share of what clients paid you.
of gross receipts is the profit you pay tax on
Say clients paid you ₹10 lakh. Taxable profit is ₹5 lakh. The other ₹5 lakh is treated as your costs: internet, a laptop, travel, software, and the rest. The tax department accepts that split without asking for those bills, as long as you stay inside the section.
Higher limit if you are paid digitally
The usual receipt cap is ₹50 lakh. If cash is under 5% of receipts, the cap is ₹75 lakh. Bank transfer, UPI, and card payments count as digital. See the CBDT presumptive page.
This is a section of the Income-tax Act, written for small professional practices. It is not a side route around the Act.
