I need the most accurate and appropriate codes for both categories so that I do not receive any notice from the Income Tax Department for using an incorrect or non-compliant business/profession code.
For Section 44AD, there isn’t a very specific code only for selling software licenses online. You can use 09028 – Retail sale via internet / e-commerce (commonly used for online product sales). Another option could be 21008 – Other services, if your activity doesn’t fit perfectly into a specific category.
For Section 44ADA, software consultancy generally falls under 16005 – Engineering and technical consultancy.
