Taxes for freelancers vs W-2 employee

The tax system in the US works on a pay-as-you-go basis, so the IRS collects income taxes throughout the year via payroll. Ideally, if you are a W-2 employee, you automatically get your taxes withheld by your employer. However, as a freelancer, taxes aren’t a cakewalk. They have to pay a bit extra in “self-employment tax” to contribute to Social Security and Medicare.

CPA advice for freelancers

If you’re a W-2 employee then most likely, your taxes are already being withheld for you by your employer and you typically get a tax refund. Freelancers, self-employed individuals, and business owners have to handle their own taxes including the quarterly estimated tax payments.
