How this Georgia income tax calculator works

This calculator estimates your Georgia state income tax using a flat state tax rate on taxable income, plus Georgia-specific standard deductions and personal exemptions that vary by filing status and dependents.

Because Georgia law and rates can change, the calculator uses a simplified, transparent model that is easy to understand and adjust. For exact, up-to-date figures, always confirm with the Georgia Department of Revenue or a qualified tax professional.

Step 1 – Start from your Georgia-adjusted income

We begin with your annual gross income and subtract any pre-tax deductions you enter (401(k), HSA, etc.):

GA_adjusted_income = Gross_income − Pre_tax_deductions

Step 2 – Subtract Georgia standard or itemized deductions

Next, we subtract either the Georgia standard deduction for your filing status, or the itemized deduction amount you provide.

Illustrative standard deduction amounts used in this tool:

  • Single / Married filing separately: $5,400
  • Married filing jointly: $7,100
  • Head of household: $7,100
Taxable_base = GA_adjusted_income − max(Standard_deduction, Itemized_deductions)

Step 3 – Subtract Georgia personal exemptions

Georgia allows personal exemptions for the taxpayer, spouse, and dependents. To keep the tool simple and transparent, we approximate exemptions as:

  • Single / Head of household: $2,700 for the taxpayer
  • Married filing jointly: $7,400 for taxpayer + spouse
  • Married filing separately: $3,700 for the taxpayer
  • Dependents: $3,000 per dependent (all statuses)
GA_taxable_income = max(0, Taxable_base − Personal_exemptions)

Step 4 – Apply the Georgia state tax rate

Georgia currently uses a flat state income tax rate on taxable income. In this calculator we model that as:

GA_state_tax_before_credits = GA_taxable_income × 5.49%

Then we subtract any Georgia tax credits you enter (for example, child tax credits or other state credits):

GA_state_tax = max(0, GA_state_tax_before_credits − GA_credits)

Effective vs. marginal Georgia tax rate

  • Marginal rate – the rate applied to your last dollar of Georgia taxable income (here, the flat rate of 5.49%).
  • Effective rate – your total Georgia tax divided by your gross income:
    Effective_rate = GA_state_tax ÷ Gross_income

Limitations and important notes

  • This calculator covers Georgia state income tax only, not federal or FICA taxes.
  • It does not handle every special Georgia rule (e.g., detailed retirement income exclusions, capital gains preferences, or all available credits).
  • Georgia tax law is subject to change. Use this tool for education and planning, not for filing your return.

Frequently asked questions about Georgia income tax

Does Georgia tax Social Security benefits?

Georgia does not tax Social Security retirement benefits. In addition, Georgia offers a retirement income exclusion for qualifying taxpayers over a certain age, which can reduce or eliminate state tax on other retirement income such as pensions or IRA withdrawals. The exact exclusion amount depends on your age and filing status.

Are Georgia state income taxes deductible on my federal return?

Yes, Georgia state income taxes can be deductible on your federal return if you itemize deductions instead of taking the federal standard deduction. However, the total deduction for state and local taxes (SALT) is currently capped under federal law, which may limit the benefit.

How do Georgia tax brackets work?

Georgia has been transitioning from a traditional multi-bracket system to a flat income tax rate. Under a flat tax, all taxable income is taxed at the same rate, but your effective rate is lower because of deductions and exemptions. This calculator models that flat rate and shows both your effective and marginal rates.

When are Georgia income taxes due?

Georgia individual income tax returns are generally due on the same date as the federal tax deadline (usually April 15, or the next business day if that falls on a weekend or holiday). Extensions may be available, but any tax owed is still due by the original deadline to avoid penalties and interest.
