How 1099 Taxes Work in 2026
As a 1099 contractor you pay two separate taxes on your net profit: self-employment tax and income tax.
Self-Employment Tax (15.3%)
SE tax = net profit × 92.35% × 15.3%. The 92.35% factor exists because employees only pay 7.65% FICA (employer pays the other half). As self-employed, you pay both halves. Good news: you can deduct half of SE tax paid from your gross income, reducing your federal income tax.
Federal Income Tax
After subtracting half of SE tax and the standard deduction from your adjusted gross income, your taxable income is taxed at the 2026 bracket rates (10% / 12% / 22% / 24% / 32% / 35% / 37%).
