Single filer, standard deduction. Total tax = SE tax + federal income tax + Georgia state tax. Estimates only.
The federal self-employment (SE) tax rate is 15.3% (12.4% Social Security plus 2.9% Medicare), the same in every state including Georgia. It applies to 92.35% of your net self-employment profit. Social Security stops at $176,100 of net earnings; Medicare has no cap and adds 0.9% above $200,000.
Multiply your net profit by 92.35%, then apply 15.3%. For example, on $60,000 of net profit the SE tax is about $8,478. You can deduct half of that (about $4,239) from your income before figuring income tax.
Georgia also taxes self-employment income as ordinary income (Flat 5.49%). This calculator adds federal income tax and Georgia state income tax on top of SE tax to estimate your total liability and quarterly payments.
A common rule of thumb is 25% to 35% of net profit. On $60,000 of net profit in Georgia, estimated total tax (SE + federal + state) is about $15,368, or roughly $3,842 per quarter. Use the calculator above for your own numbers.
Business expenses that lower net profit (equipment, software, home office, mileage, marketing) reduce both SE tax and income tax. The deductible half of SE tax, self-employed health insurance, and retirement contributions (SEP-IRA, Solo 401k) reduce income tax.
