This discussion helps individuals determine the correct Income Tax Return (ITR) form when they have both salary income and income from a business (like printing) and training. The primary question revolves around choosing between ITR 4, ITR 3, or ITR 2 based on the nature and quantum of business income. Advice suggests ITR 4 is suitable if printing income is treated as business income, while ITR 3 might be relevant for specific business structures. The discussion also touches upon GST implications and how to declare income from training as professional income.
