If you live in Atlanta, you pay Georgia’s 5.19 percent flat state income tax for the 2026 tax year, a combined state and local sales tax of roughly 8.9 percent on most retail purchases, and property tax calculated on 40 percent of your home’s fair market value at millage rates set by the city, your county, and the school board.1Department of Revenue. Important Tax Updates Each layer has its own deductions, exemptions, and deadlines, and the income tax rate is still dropping each year.
Georgia Income Tax Rate
Georgia switched from a graduated income tax to a flat rate starting in 2024, and the rate falls by 0.10 percentage points each year until it reaches 4.99 percent. For 2026 the rate is 5.19 percent of your Georgia taxable net income.1Department of Revenue. Important Tax Updates The scheduled path:
- 2024: 5.39 percent
- 2025: 5.29 percent
- 2026: 5.19 percent
- 2027: 5.09 percent
- 2028: 4.99 percent (target floor)
Each annual reduction is contingent on state revenue conditions. If revenue falls short of certain benchmarks, a scheduled cut can be delayed.2Justia. Georgia Code 48-7-20 – Individual Tax Rates The same flat rate applies to full-year residents, part-year residents on the income they earned while living in Georgia, and nonresidents on income they earn from Georgia sources.
How Your Taxable Income Is Figured
Your Georgia return starts with your federal adjusted gross income, then applies Georgia-specific additions and subtractions. In practice, most of the work you did on your federal return carries straight over.
Under the flat tax system, the standard deduction is $12,000 for single and head-of-household filers, with a higher amount for married couples filing jointly. These replaced the smaller personal exemptions and standard deductions that existed under the old graduated structure. You claim the deduction on Georgia Form 500, and the 5.19 percent rate applies to what remains.
Social Security and Retirement Income
Georgia does not tax Social Security benefits. Any Social Security income on your federal return gets subtracted when you figure your Georgia taxable income.
Georgia also offers a retirement income exclusion for taxpayers age 62 and older. Qualifying income includes pensions, annuities, interest, dividends, capital gains, rental income, royalties, and up to $5,000 of earned income. Filers between 62 and 64 can exclude up to $35,000 per person; those 65 and older can exclude up to $65,000 per person, which means a married couple both 65 or older filing jointly can shelter up to $130,000. Confirm current thresholds against the worksheet in the IT-511 instruction booklet for your filing year.3Department of Revenue. Retirement Income Exclusion
Sales Tax in Atlanta
Georgia’s base sales tax is 4 percent, but inside Atlanta’s city limits several local taxes stack on top.4Department of Revenue. Tax Rates The components:
- State sales tax: 4 percent
- MARTA tax: 1 percent, funding the regional transit system in Fulton, DeKalb, and Clayton counties5MARTA. Top Questions About the MARTA Transit Sales Tax
- Municipal Option Sales Tax (MOST): 1 percent, dedicated to city water and sewer infrastructure
- Education Local Option Sales Tax (ELOST): 1 percent, funding local school construction
- Additional county and special-purpose levies that bring the combined rate to roughly 8.9 percent
The exact combined rate shifts slightly depending on where in Atlanta your purchase happens, since the city spans portions of Fulton and DeKalb counties. Some special-purpose taxes expire and get renewed by voter referendum, so the total changes periodically. The Georgia Department of Revenue publishes updated rate charts quarterly with the precise figure for each jurisdiction.
What’s Exempt
Georgia exempts most unprepared groceries from the 4 percent state sales tax, though local taxes may still apply at a reduced rate. Prescription drugs are also exempt from state sales tax. Prepared food, restaurant meals, and most beverages other than plain water are fully taxable at the combined rate.
Property Tax in Atlanta
Property tax depends on which county your home sits in. Most of Atlanta falls within Fulton County, but portions extend into DeKalb County, and each county’s Board of Assessors determines your home’s fair market value. Georgia law sets the taxable assessed value at 40 percent of that fair market value.6Justia. Georgia Code 48-5-7 – Assessment of Tangible Property
Millage rates from the city, county, and school board are then applied to that assessed value. One mill equals $1 of tax per $1,000 of assessed value. The average combined millage rate across Georgia counties is roughly 30 mills, but Atlanta residents often pay above that average because city and Atlanta Public Schools millage rates layer on top of the county rate.
A rough example: a home with a fair market value of $400,000 has an assessed value of $160,000. At a combined millage rate of 35 mills, the annual property tax bill before exemptions would be $5,600. Homestead exemptions can cut that figure meaningfully.
Homestead Exemptions
If you own and occupy your Atlanta home as your primary residence on January 1 of the tax year, you qualify for Georgia’s standard homestead exemption, which removes $2,000 from the 40 percent assessed value for county and school tax purposes.7Department of Revenue. Property Tax Homestead Exemptions That’s the floor. Additional exemptions apply to:
- Seniors age 62 and older: additional school tax exemptions if household income falls below certain thresholds
- Seniors age 65 and older: a $4,000 exemption from school taxes, with income limits tied to the federal Social Security maximum benefit
- Disabled veterans: exemption from all ad valorem taxes up to $121,812 in assessed value for the 2025 tax year
- Surviving spouses of military members killed in service: the same $121,812 exemption amount
Fulton and DeKalb counties also offer locally enacted exemptions that can exceed the state minimums, and some counties use a “valuation freeze” that locks your assessed value at the amount from the year you first qualified.7Department of Revenue. Property Tax Homestead Exemptions Apply by April 1 of the tax year, or within the 45-day window to appeal your assessment notice, whichever is later. Exemptions aren’t automatic.
If You Pay Late
Georgia law imposes a 5 percent penalty on unpaid ad valorem tax after 120 days, with an additional 5 percent every 120 days the balance remains outstanding, up to a maximum of 20 percent. Interest accrues on top of the penalties.8Justia. Georgia Code 48-2-44 – Penalty and Interest on Failure to Pay Ad Valorem Tax Prolonged nonpayment can lead to a tax lien and eventually a tax sale. Fulton County’s specific due dates vary year to year, so check the tax commissioner’s website each fall.
Filing Your Georgia Return
Georgia individual income taxes are filed on Form 500, available on the Georgia Department of Revenue website along with the IT-511 instruction booklet.9Department of Revenue. 500 Individual Income Tax Return You’ll need your Social Security number or ITIN, W-2s, 1099s for interest, dividends, or freelance income, and documentation for any Georgia-specific deductions or credits. Because your return starts with federal adjusted gross income, finish your federal return first.
The Georgia Tax Center is the state’s online portal for filing, paying, and tracking your return. You can pay a balance by electronic check or credit card.10Georgia.gov. File Individual State Income Taxes Paper filers mail Form 500 to the address in the DOR instructions. The deadline is April 15, 2026, matching the federal due date.11Department of Revenue. Taxes
Extensions and Late Penalties
Georgia grants an automatic six-month extension to file if you’ve already received a federal extension. You can also file Georgia Form IT-303 separately. An extension gives you more time to file; it does not extend the deadline to pay.12Department of Revenue. Requesting an Extension If you owe and don’t pay by April 15, interest and penalties start accruing even with a valid extension on file. Estimate what you owe and send a payment with the extension request.
The late filing penalty is 5 percent of the unpaid tax for each month overdue, capping at 25 percent. The late payment penalty is a separate 0.5 percent per month, also capping at 25 percent, though the two combined cannot exceed 25 percent of the tax due. Interest accrues on top at the federal prime rate plus 3 percent, adjusted each January.13Department of Revenue. Penalty and Interest Rates Because the late filing penalty accumulates ten times faster than the late payment penalty, file on time even if you can’t pay in full, and set up a payment plan through the Georgia Tax Center for the balance.
If You Moved In or Out of Atlanta
Part-year residents are taxed on income earned while they were Georgia residents plus any Georgia-sourced income earned while living elsewhere. Wages are allocated based on where you were living when you earned them; unearned income like dividends and interest is assigned to wherever you were a resident when you received it.
Nonresidents who work in Atlanta or earn Georgia-source income generally must file a Georgia return if they also have to file a federal one. One narrow exception: if your only Georgia activity is working as an employee and your Georgia compensation is both less than $5,000 and less than 5 percent of your total income from all sources, you don’t need to file.14Department of Revenue. Filing Residents, Nonresidents, and Part-Year Residents – FAQ That threshold is low enough that most people drawing regular wages in Atlanta will owe a return regardless of where they sleep.
