Last updated: May 2026 · Data: MIT Living Wage Calculator, C2ER, U.S. Census, BLS, IRS, state and city sources
Chattanooga self-employed workers pay federal SE tax and federal income tax, but no Tennessee state income tax. Tennessee has no state income tax on wages or salaries. The state previously taxed interest and dividend income (the Hall Tax), but this was fully repealed as of January 2021. Tennessee relies on its 7% sales tax for revenue.

The federal SE tax rate is 15.3% (12.4% Social Security plus 2.9% Medicare), the same in Chattanooga as everywhere. It applies to 92.35% of net profit; Social Security stops at $176,100 of net earnings.
Tennessee has no state income tax, so self-employment income earned in Chattanooga is not subject to state tax, only federal SE and income tax.
On $60,000 of net profit in Chattanooga, estimated total tax (SE plus federal) is about $13,131, or roughly $3,283 per quarter.
Chattanooga does not levy a local self-employment or income tax. Tennessee does not levy a local business income tax, but the state imposes a business tax on gross receipts collected for the state and the local jurisdiction, and Chattanooga and Hamilton County require a business license. Budget for the state and local business tax and the Tennessee LLC fees 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.
