Hey guys! I'm working as an associate at law firm. I earn from other work also. From april 2023-march 2024, my income will be in between 7.3 Lakhs to 7.5lakhs. i have no investment and my friend told me that we'll be taxed under professional income slab and not salaried. How do I apply for deductions and how much and where should I invest to save money and pay zero tax?
