Understanding Your 2026 Taxes
For 2026, this calculator assumes the sunset of the Tax Cuts and Jobs Act (TCJA), reverting to pre-2018 bracket structures adjusted for inflation. As a freelancer, you are responsible for both the employer and employee portions of Social Security and Medicare taxes.
Tip: To avoid underpayment penalties, the IRS generally requires you to pay at least 90% of your current year's tax or 100% of last year's tax through quarterly estimated payments.
