Employee vs. independent contractor
IRS uses a facts‑and‑circumstances test
→ Review the 20‑factor list in the instructions
Who should sign
Both employer and worker can sign, but only one signature is required
→ Ensure the signer is authorized
What counts as an attachment
Some think a simple email is enough
→ Provide full written contracts or detailed work orders
Using the form for a previously issued ruling
The original SS‑8 number must be referenced
→ Include the prior determination letter
State law considerations
Federal classification differs from state rules
→ Verify state requirements separately
