About 64 million Americans do some form of freelance or contract work. If you’re paid on a 1099 instead of a W-2, your tax situation is dramatically different. Here’s everything you need to know.
Self-employment brings tax complexity but also opportunities. While you pay more in SE tax, you gain access to deductions and retirement plans that can significantly reduce your burden. Understanding the difference between your marginal and effective tax rate is even more important for 1099 workers.
Quick answer: 1099 workers pay 15.3% self-employment tax plus income tax (10-37%). Total effective rate: 25-40%. Key deductions: home office ($1,500), health insurance (100%), SEP IRA ($69,000 max), vehicle (67¢/mile).

S-Corp Election: The SE Tax Hack
If net SE income exceeds ~$60,000, an S-Corp election can save thousands on SE tax:
| Scenario | Sole Proprietor | S-Corp |
|---|---|---|
| Net business income | $120,000 | $120,000 |
| Reasonable salary | N/A | $70,000 |
| Distributions (not subject to SE tax) | N/A | $50,000 |
| SE tax (15.3% of applicable income) | $16,956 | $10,710 (only on $70K salary) |
| SE tax savings | — | $6,246/year |
| Additional S-Corp costs | $0 | ~$2,000 (payroll, tax prep) |
| Net savings | — | ~$4,246/year |
The S-Corp saves money because distributions (above reasonable salary) avoid the 15.3% SE tax.
