The federal SE tax rate is 15.3% (12.4% Social Security plus 2.9% Medicare), the same in Louisville as everywhere. It applies to 92.35% of net profit; Social Security stops at $176,100 of net earnings.
Kentucky taxes self-employment income as ordinary income (Flat 4%), so Louisville freelancers owe state tax on top of federal.
On $60,000 of net profit in Louisville, estimated total tax (SE plus federal plus state) is about $14,761, or roughly $3,690 per quarter.
Louisville Metro levies a 2.2% occupational license (payroll) tax on wages earned in the jurisdiction and on business net profits. The calculators on this page show federal, Kentucky, and FICA amounts, so people who live or work in Louisville Metro should add the 2.2% occupational tax on top. Kentucky does not levy a separate local business income tax, but Louisville Metro imposes an occupational license (payroll and net-profits) tax that applies to LLC owners' earnings and business profits. Budget for that and the Kentucky LLC annual report on top of the state 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.
