Georgia's income tax is a state tax on wages, investment income, and other earnings

Georgia taxes income at a flat rate of 5.75 percent on most types of earnings. This is separate from federal income tax — you pay both. The state applies this rate to wages from a job, self-employment income, interest, dividends, and retirement distributions. Georgia does not tax Social Security benefits, and it offers a deduction for retirement income (including pensions and 401(k) withdrawals) once you reach age 65.

The 5.75 percent rate applies to your taxable income, which is your total income minus deductions and exemptions. Georgia uses federal taxable income as a starting point, then makes its own adjustments. Most people file a Georgia return if they earned income in the state during the tax year, regardless of where they live now.

Key Takeaways

  • Georgia's flat income tax rate is 5.75 percent on most types of income, applied after deductions and exemptions.
  • You file a Georgia return if you earned income in the state, even if you have moved away or work remotely for an out-of-state employer.
  • Georgia does not tax Social Security benefits, and residents age 65 and older can deduct retirement income including pensions and 401(k) distributions.
  • Your employer withholds Georgia income tax from your paycheck based on a W-4 form you complete; you reconcile what was withheld against what you owe when you file.
  • Self-employed people must pay Georgia income tax on net business income and may also owe self-employment tax to the federal government.

Who has to file a Georgia income tax return

You must file a Georgia return if you lived in Georgia for any part of the tax year and earned income there. This includes wages, self-employment income, rental income, and investment income. If you moved out of Georgia mid-year, you still file a return for the months you were a resident and earned income.

If you worked in Georgia but lived in another state, you may owe Georgia tax on the income you earned in the state, depending on your employer's location and your residency status. Some states have reciprocal agreements with Georgia, meaning you may not owe Georgia tax if you live in a neighboring state and your employer is there. Check with Georgia Department of Revenue if you worked across state lines.

Nonresidents who earned income only in Georgia must file a Georgia return on that income. You do not need to file if your income was below the threshold for your filing status, though filing may result in a refund if taxes were withheld.

How withholding works and what to expect on your paycheck

Your employer withholds Georgia income tax from your paycheck based on the W-4 form you complete when hired. The W-4 tells your employer how much to withhold — the more dependents or adjustments you claim, the less is withheld. You can update your W-4 at any time if your situation changes, such as getting married, having a child, or taking a second job.

The amount withheld is an estimate. When you file your return at tax time, you compare what was actually withheld against what you owe based on your total income and deductions. If too much was withheld, you receive a refund. If too little was withheld, you owe the difference. Self-employed people do not have withholding and must pay estimated taxes quarterly to avoid owing a large amount at filing time.

Deductions and exemptions that reduce what you owe

Georgia allows a standard deduction, which reduces your taxable income before the 5.75 percent rate is applied. The standard deduction amount depends on your filing status (single, married filing jointly, head of household, and so on) and changes each year. You can claim the standard deduction or itemize deductions if itemizing results in a larger reduction — most people use the standard deduction.

Georgia also allows a personal exemption for yourself and each dependent, which further reduces taxable income. The exemption amount is set by the state and changes annually. If you are age 65 or older, you can deduct retirement income including pensions, 401(k) distributions, and IRA withdrawals, up to a limit set by the state. This deduction is one of Georgia's largest tax breaks for older residents.

You may also deduct contributions to a traditional IRA, student loan interest, and certain education expenses. Georgia does not allow a deduction for state income tax paid, unlike some other states.

Self-employment income and what you owe

If you are self-employed, you pay Georgia income tax on your net business income (revenue minus business expenses). You calculate net income on Schedule C (federal form) and use that figure on your Georgia return. Georgia taxes self-employment income at the same 5.75 percent rate as wages.

Self-employed people do not have withholding, so you must pay estimated taxes four times per year — April 15, June 15, September 15, and January 15 — to avoid owing a large amount when you file. You can pay online through the Georgia Department of Revenue website or by mail. If you underpay estimated taxes, you may owe a penalty in addition to the tax itself.

You also owe federal self-employment tax (Social Security and Medicare), which is separate from Georgia income tax. Self-employment tax is calculated on Schedule SE and is not reduced by the Georgia deductions described above.

Special situations: retirement income, investment income, and nonresidents

Georgia does not tax Social Security benefits, which is a significant advantage for retirees. However, other retirement income is taxable unless you may have access to for the retirement income deduction. If you are age 65 or older, you can deduct up to a certain amount of retirement income, including pensions, 401(k) distributions, IRA withdrawals, and annuity payments. The deduction limit is set by the state and changes yearly.

Investment income — interest, dividends, and capital gains — is taxable in Georgia at the 5.75 percent rate. Long-term capital gains (assets held more than one year) are taxed the same as ordinary income in Georgia, unlike the federal system which offers preferential rates. Short-term capital gains are taxed as ordinary income.

If you moved out of Georgia, you may still owe tax on income earned while you were a resident. Nonresidents who earned income in Georgia during part of the year file a part-year resident return. You report only the income earned during the months you were a Georgia resident.

How to file your Georgia return

You file your Georgia return using Form 500 (the main return) along with any schedules that explore to your situation, such as Schedule C for self-employment or Schedule D for capital gains. You can file online through the Georgia Department of Revenue website, by mail, or through tax software that supports Georgia returns.

The filing important date is April 15 unless that date falls on a weekend or holiday, in which case it moves to the next business day. You can request an extension, which gives you until October 15 to file, but the extension does not extend the important date to pay taxes owed — you still owe payment by April 15 or you will be charged interest and penalties.

If you are due a refund, filing early can speed up the refund. Direct deposit is the fastest way to receive a refund, typically within two to three weeks of the state accepting your return. If you mail a check, allow four to six weeks.

Frequently Asked Questions

Do I owe Georgia income tax if I work remotely for an out-of-state company?

Yes, if you live in Georgia and work remotely, you owe Georgia income tax on your wages. Your employer may not withhold Georgia tax if they are based out of state, so you may need to pay estimated taxes or adjust your W-4 to have additional tax withheld from your paycheck.

What happens if I don't file a Georgia return?

If you owe tax and do not file, Georgia charges interest and penalties on the unpaid amount. The longer the return is unfiled, the larger the penalties grow. If you are due a refund and do not file, you forfeit the refund after a certain period — typically three years.

Can I deduct federal income tax paid from my Georgia return?

No, Georgia does not allow a deduction for federal income tax paid. You can only deduct certain items such as retirement income (if age 65+), traditional IRA contributions, and student loan interest.

How much should I pay in estimated taxes if I'm self-employed?

Divide your expected annual net income by four and pay that amount quarterly. If you underpay, you may owe a penalty. Use the Georgia Department of Revenue's estimated tax worksheet to calculate the amount based on your income and deductions.

Does Georgia tax military income differently?

Georgia does not tax military retirement pay for service members who were stationed in Georgia or are Georgia residents. You must claim this exclusion on your return. Active duty military pay is taxed the same as other wages unless you may have access to for a specific military exemption.
