How Georgia Income Tax Works
Georgia taxes income at a flat 4.99% for tax year 2026. That rate is the result of HB 463, which cut the rate retroactive to January 1, 2026 — down from the 5.19% flat rate of the prior year. Before the rate applies, Georgia lets you subtract a generous standard deduction and a per-dependent deduction.
- One flat rate: 4.99%. Every dollar of Georgia taxable income is taxed at 4.99% — no brackets.
- Standard deduction: $15,000 single / $30,000 joint. Among the most generous state standard deductions in the country.
- Dependent deduction: $5,000 each. Every qualifying dependent subtracts another $5,000 from Georgia taxable income.
- No local income tax. Georgia cities and counties do not levy income taxes.
GA taxable income = gross income − standard deduction − ($5,000 × dependents)
GA state tax = taxable income × 4.99%
(taxable income cannot go below $0)
GA state tax = taxable income × 4.99%
(taxable income cannot go below $0)
Worked Example: Single, $80,000 Gross Income
| Calculation | Amount | |
|---|---|---|
| Standard deduction (single) | $15,000 | |
| Dependent deduction | 0 × $5,000 | $0 |
| GA taxable income | $80,000 − $15,000 | $65,000 |
| GA state tax | $65,000 × 4.99% | $3,243.50 |
| Effective rate | $3,243.50 ÷ $80,000 | 4.05% |
