For 2024, Georgia applies a flat 5.49% rate to taxable income. This tool computes Georgia taxable income from user-entered income, adjustments, deductions, and exemptions, and then applies the statutory flat rate.

The Formula Explained

$$\text{Taxable Income} = \max\bigl(0,\; \text{Gross} - \text{PreTax} - \text{Deduction} - \text{Exemptions}\bigr)$$
$$\text{GA State Tax} = r \times \text{Taxable Income}, \quad r = 0.0549 \; (5.49\%)$$
$$\text{Effective Rate} = \frac{\text{GA State Tax}}{\text{Gross}} \times 100\%$$
$$\text{Take\mbox{-}home (after GA tax)} = \text{Gross} - \text{GA State Tax}$$
$$\text{Per-Period Amounts} = \frac{\text{Annual Amount}}{N}, \quad N \in \{12,24,26,52\}$$

Glossary of Variables

    - Gross annual income: Your total income before any taxes or deductions. Required input.
    - Pre-tax adjustments (PreTax): Qualified amounts that reduce Georgia taxable income (e.g., certain retirement contributions, HSA/FSA, pre-tax premiums). Optional input.
    - Deduction: Either the Georgia standard deduction (varies by filing status) or your itemized deductions. Required selection.
    - Exemptions: Georgia personal exemption plus dependent exemptions. Defaults load based on filing status and dependents; editable to match your situation.
    - Taxable income: Income subject to Georgia state tax after subtracting adjustments, deduction, and exemptions; never below zero.
    - GA State Tax: Taxable income multiplied by Georgia’s 2024 flat rate (5.49%).
    - Effective state tax rate: GA State Tax as a percentage of gross annual income.
    - Per-period amounts: Annual figures divided by monthly, semi-monthly, biweekly, or weekly counts.

How It Works: A Step-by-Step Example

Scenario: Single filer with $80,000 gross, $3,000 pre-tax adjustments, standard deduction, no dependents.

  1. Defaults load: Standard deduction = $5,400 (Single), Personal exemption = $2,700.
  2. Compute taxable income: 80,000 − 3,000 − 5,400 − 2,700 = $68,900.
  3. Apply GA flat rate: 0.0549 × 68,900 = $3,784.61 state tax.
  4. Effective rate: 3,784.61 ÷ 80,000 = 4.73%.
  5. After GA tax: 80,000 − 3,784.61 = $76,215.39.
  6. Per paycheck (biweekly, 26): 3,784.61 ÷ 26 = $145.56 GA tax per check (approx.).

Note: Adjust deductions/exemptions if your documented values differ; always refer to Georgia DOR instructions for definitive amounts.

Frequently Asked Questions (FAQ)

What rate does Georgia use for 2024?

Georgia applies a flat 5.49% state income tax to taxable income for tax year 2024.

Does this calculator include federal taxes, credits, or FICA?

No. It only estimates Georgia state income tax. Federal tax, credits, and Social Security/Medicare are not included.

Yes. If your itemized deductions exceed the standard deduction, you may itemize. Select “Itemized” and enter your total amount.

How are exemptions handled?
