1099 freelancer tax guide: what every US contractor should know

If you freelance in the US, clients send you a 1099-NEC when they pay you $600 or more in a year. That form goes to you and the IRS. It reports your income. Your job is to report it on your return, claim your deductions, and pay the right amount of tax. Miss a step, and the IRS will notice.

The self-employment tax trap

Employees split Social Security and Medicare with their employer. You pay both halves. That is 15.3% on your net profit, on top of income tax. A freelancer earning $80,000 might pay around $12,000 in self-employment tax alone. Budget for it.

Deductions that actually matter

• Home office: simplified method ($5 per sq ft, max 300 sq ft) or actual expenses
• Software, equipment, and subscriptions used for work
• Health insurance premiums if you are self-employed
• Retirement contributions: SEP-IRA or Solo 401(k) can cut your taxable income
• Travel to client sites, conferences, and professional development

When the 1099 is wrong

Clients sometimes misreport. Wrong amount, wrong EIN, or they send a 1099 when the work was under $600. You still need to report your actual income. If the 1099 says $8,000 and you actually received $7,200, report $7,200 and keep records. The IRS matches 1099s to returns; discrepancies trigger letters.

“I had a client send a 1099 for a project they cancelled. I never got paid. Had to report it as income and then claim a bad debt deduction. Painful. Now I get everything in writing.”

Quarterly payments and the annual return

1099 income flows into your Schedule C. You subtract expenses to get net profit. That profit goes onto your 1040 and drives both income tax and self-employment tax. If you paid estimated tax during the year, that reduces what you owe. If you overpaid, you get a refund.
