1099 Contractor Tax Guide: What You Owe and How to Pay It
Everything independent contractors need to know about 1099-NEC income, self-employment tax, quarterly payments, and keeping enough cash aside to avoid surprises in April.

When you work as an independent contractor, clients who pay you $600 or more in a year issue a Form 1099-NEC (Non-Employee Compensation). Unlike W-2 employees, no taxes are withheld from your payments — you owe both income tax and self-employment tax, and you're responsible for paying them yourself throughout the year.
Self-Employment Tax: The Big Surprise
Self-employment tax is 15.3% on the first $176,100 of net earnings (2025), plus 2.9% Medicare on amounts above that. It covers Social Security and Medicare — taxes that employees split with their employer. As a contractor, you pay the full amount. However, you can deduct 50% of SE tax from your gross income.
What You Actually Owe
- Self-employment tax (15.3%): on your net profit after deductions
- Federal income tax: marginal rates from 10% to 37% based on taxable income
- State income tax: varies by state — nine states have no income tax
- Combined effective rate for a typical freelancer: 25–35% of net profit
The Set-Aside Rule
A practical guideline: set aside 25–30% of every client payment for taxes. For higher earners or those in high-tax states, 35% is safer. Open a separate savings account specifically for this purpose — the money isn't yours until you've filed your return.
Every tracked expense reduces your net profit — which lowers both income tax and self-employment tax. ReceiptOne captures deductions you'd otherwise miss.
Quarterly Estimated Payments
If you expect to owe $1,000 or more in taxes for the year, the IRS requires quarterly estimated payments. Missing or underpaying these triggers an underpayment penalty — typically small but avoidable. Pay by April 15, June 16, September 15, and January 15.
