How Salaried Employees Should Report Side-Business Income in Tax Returns
A person can have a regular job and also earn money from a side business.
The salary and side-business earnings are calculated separately for tax purposes.
Regular side-business income is usually treated as business or professional income.
The person may need to use ITR-3 or ITR-4, depending on whether they choose presumptive taxation.
Business expenses can usually be subtracted from business income.
Salary expenses cannot generally be claimed in the same way.
TDS deducted by an employer or client may not cover the entire tax bill.
Advance tax may be required if the remaining yearly tax liability is at least ₹10,000.
Regular side-business earnings are generally reported as “Profits and Gains from Business or Profession,” separately from salary income.
Taxpayers generally use ITR-3, or ITR-4 when choosing the presumptive taxation scheme.
If an audit is not required, income earned in FY 2025-26 must be reported by August 31, 2026, according to the article.
Business-related expenses can generally be deducted from revenue, while salaried employees instead claim permitted deductions and exemptions.
Advance tax may apply when net annual tax liability is ₹10,000 or more, and GST registration may be required after applicable revenue thresholds are crossed.
