What is Advance Tax?
Advance tax is paying income tax in installments during the financial year instead of a lump sum at year-end. If your tax liability exceeds ₹10,000 in a year, advance tax is mandatory.
- All freelancers/consultants with estimated tax > ₹10,000
- Applies whether you use Section 44ADA or regular accounting
- TDS deducted by clients does NOT exempt you from advance tax
- Even salaried employees with freelance side income may need to pay
