Frequently Asked Questions
W-2 employees split payroll taxes (Medicare and Social Security) with their employer. As a 1099 freelancer, you are both the employer and employee, so you are legally required to pay the full 15.3% tax yourself.
No! The 15.3% SE tax is completely separate and in addition to your standard federal and state income taxes. This is why freelancers must save roughly 30% of their income for taxes.
