Government rules to follow
- SAC code
- Every service invoice carries the SAC code; the GST rate depends on it (18% for most services).
- TDS by your clients
- Income-tax Act, 2025: clients deduct TDS on fees and contract payments. Match it with your tax credit statement before filing.
- Professional tax
- State law: deducted from salaries and paid to the state or local body. Tamil Nadu collects it half-yearly.
- Contracts
- Indian Contract Act, 1872: the work order or contract decides what you can bill and when.
