Income from Salary & other Income

This discussion seeks guidance on the correct Income Tax Return (ITR) form for an individual with multiple income streams. The individual earns salary from both full-time and part-time employment, alongside additional income from bookkeeping and document preparation. The core question is whether all these incomes can be declared under the 'Salary' head and which specific ITR form is most appropriate, with a suggestion towards ITR-4 or ITR-1.
