OpenWhy it matters
If a crew pays you on a 1099, no tax is taken out.
If you run the crew, see our contractor guide for payroll rules.
A tax pro can help you catch up either way.
- Employers withhold and pay taxes on employees. They generally do not on independent contractors. Calling a worker the wrong one can leave you owing.
- Self employment tax is 15.3%: 12.4% for Social Security and 2.9% for Medicare. No boss pays half for you.
- For 2025 through 2028, workers may deduct qualified overtime pay above their regular rate, like the "half" in time and a half.
What a tax pro may ask you

- If you were paid on a W-2, a 1099 or both
