Do I pay extra tax on my side hustle?
Your employer deducts PAYE from salary. Side income above the threshold requires additional filing. If your side income is small, it may already be covered by your PAYE.
Example:
Salary of ₦3M (PAYE paid) + side hustle of ₦500K = May need to file combined return.
What You Can Deduct
✓Equipment for side business
✓Materials and supplies
✓Internet (business portion)
✓Transport for side work
✓Marketing and advertising
Common Mistakes to Avoid
- ✗Assuming salary tax covers everything
- ✗Not tracking side income separately
- ✗Missing filing deadline for additional income
