Georgia charges a flat state income tax on most types of earned and unearned income. For 2026, the rate is 5.39%. Recent legislation is accelerating annual rate cuts of 0.125 percentage points, bringing the rate to 4.99% and eventually down to 3.99% over the coming years. Here’s what you need to know about how the tax works, who has to file, and what deductions and exclusions can lower your bill.
The Current Tax Rate
Georgia moved from a graduated income tax bracket system to a single flat rate starting in 2024. For 2026, the rate drops to 4.99%, down from 5.19% in the prior year. The state legislature approved a plan to reduce the rate by 0.125 percentage points each year until it reaches 3.99%. That means the rate will continue falling annually for several more years, assuming no changes to the law.
The flat rate applies to your Georgia taxable income, which is your federal adjusted gross income modified by Georgia’s own standard deduction and any state-specific adjustments. Unlike the federal system, there are no separate brackets where different slices of income are taxed at different rates.
Who Needs to File
You need to file a Georgia state income tax return if you’re a full-year resident and your gross income exceeds $12,000 (or $24,000 for married couples filing jointly). You also need to file if you’re required to file a federal return or if you have income subject to Georgia tax that isn’t taxed at the federal level.
Part-year residents who earned income while living in Georgia generally need to file as well. Nonresidents who earn certain types of Georgia-sourced income, such as wages from a Georgia employer, Georgia lottery winnings, or income flowing through Georgia-based S-corporations, partnerships, or LLCs, are also required to file a state return.
Standard Deduction
Georgia offers its own standard deduction, which reduces your taxable income before the flat rate is applied. The deduction amounts depend on your filing status. Joint filers receive a higher deduction than single or head-of-household filers. These amounts are set by state law and may differ from the federal standard deduction, so don’t assume they match what you claim on your federal return. Check the current year’s Form IT-511 instruction booklet from the Georgia Department of Revenue for exact figures.
Retirement Income Exclusion
Georgia provides a meaningful tax break for retirees. If you’re 62 or older, or permanently and totally disabled at any age, you can exclude a portion of your retirement income from state tax. The exclusion covers a broad range of income types: pensions, annuities, interest, dividends, capital gains, rental income, royalties, and up to $5,000 of earned income. The Georgia Department of Revenue publishes the maximum exclusion amount each year in its individual income tax instruction booklet.
For married couples filing jointly where both spouses qualify, the exclusion can be doubled, with each spouse claiming the full individual amount on their own qualifying income. Each spouse must independently meet the age or disability requirement.
Military retirees get an additional benefit. If you’re under 62, you can exclude up to $17,500 of military retirement income. If you also have more than $17,500 in earned income from Georgia sources, you can exclude an additional $17,500 on top of that. These amounts apply per qualifying taxpayer, so a married couple where both spouses receive military retirement pay could each claim the exclusion separately.
How Georgia Taxable Income Is Calculated
Georgia starts with your federal adjusted gross income as the baseline. From there, you subtract the Georgia standard deduction (or itemized deductions, if you choose to itemize at the state level). You then apply any Georgia-specific adjustments, like the retirement income exclusion. The result is your Georgia taxable income, and the flat rate is applied to that number.
Because the starting point is federal AGI, most of the same income sources count: wages, self-employment income, investment gains, rental income, and retirement distributions. Social Security benefits that are excluded from federal taxable income generally stay excluded at the state level too.
Filing Deadlines and Payment
Georgia’s income tax return is due on the same date as the federal return, typically April 15. If that date falls on a weekend or holiday, the deadline shifts to the next business day. You can request an extension for additional time to file, but an extension only delays the paperwork, not the payment. If you owe tax, you’re expected to pay by the original deadline to avoid interest and penalties.
The state accepts electronic filing through its Georgia Tax Center portal, and most major tax software programs support Georgia returns. If your employer withholds Georgia income tax from your paycheck, those withholdings are credited against your total tax liability when you file. Self-employed workers and people with significant non-wage income typically need to make quarterly estimated payments throughout the year to avoid an underpayment penalty.
