Georgia income tax goes up to 5.19% at the top bracket. Calculate your combined federal + state effective tax rate for 2026. Formula shown, sources cited — no account required.
Georgia's flat 5.19% income tax rate applies uniformly to all taxable income above the standard deduction and personal exemption amounts. The flat structure means no bracket thresholds to track — every additional dollar of income costs exactly 5.19 cents at the state level. For a median earner at $79,991, the state tax bill runs roughly $4,151 before exemptions and deductions reduce the taxable base. Georgia conforms closely to federal AGI definitions, and the state standard deduction is set separately from the federal amount. One notable Georgia-specific benefit is the retirement income exclusion, which reduces state tax for taxpayers over a certain age — a benefit that matters for workers approaching retirement. At the combined federal and state level, the median Georgia household faces an effective all-in rate typically in the 20–24% range.

Georgia Tax Brackets Explained (2026)
Georgia has a state income tax with a top marginal rate of 5.19%. On top of federal rates (10%–37%), residents can face a combined marginal rate exceeding 35% at higher income levels. However, your effective rate is always lower than the marginal rate because only income above each threshold is taxed at that bracket's rate.
The median household in Georgia earns $79,991/year. At that income (single filer), the federal effective rate is approximately 12–14%, bringing total income tax (federal + state) to roughly 15–18%.
How Marginal vs. Effective Rate Works
The marginal rate is the rate on your last dollar of income — it does not apply to all income. The effective rate is your total tax divided by total income. For example, someone earning $100,000 in Georgia has a 22% federal marginal rate but an effective federal rate of roughly 15%, because the first $44,725 (2024) is taxed at 10% and 12%, not 22%.
