Methodology
How Georgia income tax is calculated
Georgia applies a single flat rate of 4.99% to all taxable income. The standard deduction for Georgia single filers is $15,000. Taxable income equals gross income minus your deduction (standard or itemized).
Formula
Taxable income = Gross income − Deduction Georgia tax = Taxable income × 4.99%
Tax year scope
This calculator uses 2026 tax year rates as published by the Georgia Department of Revenue.
Marginal vs. effective rate
Because Georgia uses a flat rate, your marginal and effective state income tax rates are the same percentage (4.99%). Your effective rate as a share of gross income will be lower because the deduction reduces taxable income before the rate is applied.
Limitations
- Covers state income tax only — federal income tax is separate.
- Does not account for tax credits, phase-outs, or alternative minimum tax provisions.
- Local income taxes (where applicable) are not modeled.

For flat-rate states like Georgia, your marginal rate and effective rate are the same percentage — both equal the flat rate (4.99%). However, the effective rate as a share of your gross income will be lower than 4.99% because your deduction reduces taxable income before the rate is applied.
