What you still owe

South Dakota doesn't tax your freelance profit, but the IRS does. You still owe self-employment tax (15.3% on most of your profit, for Social Security and Medicare) plus federal income tax, and you still make federal quarterly estimated payments.

That makes your set-aside lower than in most states, but rarely below 15% once you're earning a real profit.
