Frequently Asked Questions

The federal SE tax rate is 15.3% (12.4% Social Security plus 2.9% Medicare), the same in Saint Louis as everywhere. It applies to 92.35% of net profit; Social Security stops at $176,100 of net earnings.

Missouri taxes self-employment income as ordinary income (2% to 5%), so Saint Louis freelancers owe state tax on top of federal.

On $60,000 of net profit in Saint Louis, estimated total tax (SE plus federal plus state) is about $14,977, or roughly $3,744 per quarter.

St. Louis levies a 1% earnings tax on the wages of residents and of non-residents who work in the city, and on business net profits earned in the city. The calculators on this page show federal, Missouri, and FICA amounts, so people who live or work in St. Louis should add the 1% earnings tax on top. Missouri does not levy a statewide local business income tax, but St. Louis applies its 1% earnings tax to business net profits earned in the city and adds a payroll expense tax and business license. Budget for the earnings tax and these costs on top of the Missouri LLC filing fee.

Business expenses that lower net profit (equipment, software, home office, mileage) reduce both SE tax and income tax. The deductible half of SE tax, self-employed health insurance, and retirement contributions reduce income tax.
