How the 2026 numbers are calculated
- Net profit is your 1099 income minus deductible business expenses (Schedule C).
- Self-employment tax is 15.3% of 92.35% of net profit: 12.4% Social Security on the first $184,500 of combined wages and net earnings, plus 2.9% Medicare on all of it. An extra 0.9% Medicare tax applies above $200,000 ($250,000 married filing jointly).
- Adjusted gross income is net profit plus any W-2 wages, minus half of the self-employment tax.
- The standard deduction ($16,100 single, $32,200 married filing jointly, $24,150 head of household) and the 20% qualified business income deduction reduce taxable income. The QBI deduction starts phasing out above $201,750 of taxable income ($403,500 joint).
- Federal income tax is applied to what is left using the 2026 brackets for your filing status.
- The child tax credit ($2,200 per child under 17, $500 per other dependent) reduces income tax; up to $1,700 per child is refundable and can offset self-employment tax.
- The earned income credit for filers with children — up to $4,427 with one child, $7,316 with two, $8,231 with three or more — is fully refundable and phases out above $23,890 of income ($31,160 joint).
- Georgia income tax: calculated under the state's own rules, described below.
Georgia and self-employment income
Georgia replaced its graduated brackets with a flat rate in 2024 and is cutting it by roughly 0.1 percentage point a year: 5.19% for 2025, with 5.09% scheduled for 2026 if revenue targets are met. Freelancers get the standard deduction and a $4,000 deduction per dependent.
Georgia rules used by this calculator (2025)
- Georgia applies a flat 5.19% rate for 2025.
- Standard deduction: $12,000 single, $24,000 married filing jointly, $12,000 head of household.
- Each dependent adds a $4,000 deduction.
- Georgia starts from federal AGI, so the deductible half of self-employment tax reduces state income as well.
What a Georgia freelancer may still owe
- Georgia requires estimated payments (Form 500-ES) when you expect to owe more than $500 for the year.
- Every business needs an occupational tax certificate from its city or county, priced on gross receipts or a flat fee.
Quarterly estimated tax deadlines (2026)
If you expect to owe $1,000 or more of federal tax for the year, the IRS expects four estimated payments (Form 1040-ES). Georgia runs its own estimated-payment schedule with its own threshold (see above); the calculator's per-quarter figure combines federal and state so you can set aside one amount.
- Federal payment 1: April 15, 2026
- Federal payment 2: June 15, 2026
- Federal payment 3: September 15, 2026
- Federal payment 4: January 15, 2027
The calculator splits your total into four equal payments. To avoid an underpayment penalty you can instead pay 100% of last year's total tax (110% if your prior-year AGI was over $150,000) spread across the four dates.
Common questions
Does Georgia tax self-employment income differently from wages?
For state income tax, net profit from self-employment is ordinary income like wages. The self-employment tax itself is federal only; Georgia does not add a state equivalent.
Is half of self-employment tax really deductible?
Yes, for federal tax. The employer-equivalent half is an adjustment to income on Schedule 1, which lowers your AGI and therefore your federal income tax. It does not reduce the self-employment tax itself.
Does an LLC change these numbers?
A single-member LLC taxed as a sole proprietorship pays exactly what this calculator shows. Electing S-corporation status changes the math (salary plus distributions) and is outside this tool's scope.
What if I moved to Georgia during the year?
Income earned while you were a resident of another state is taxable there under that state's rules. This calculator assumes all income was earned as a Georgia resident.
