How to File the Georgia ST-3 Sales and Use Tax Return

To file the Georgia ST-3 sales and use tax return, log in to the Georgia Tax Center, enter your taxable sales broken down by county, complete Parts A through D of the return, and submit it with payment by the 20th of the month following your reporting period. The form reports state tax, county-level local taxes, and transportation local option taxes separately, so the work is less about arithmetic and more about sourcing each sale to the right jurisdiction.

If you had no activity during the period, you still owe a return. File a zero return by checking the “No Sales/Use Tax Activity” box; skipping it is one of the fastest ways to trigger penalties and put your registration at risk.¹

What to Gather Before You Open the Form

The ST-3 asks for more granular data than a single-rate state return because Georgia layers a 4% state sales tax with several county-level local option taxes.² Those local levies — Local Option (LO), Special Purpose (SP), Educational (ED), Homestead (HO), and TSPLOST — push combined rates to between 6% and 8% or higher in most counties. Pull together the following before you start:

Gross taxable sales by county, sourced to where the item was delivered or the service performed, not where your business sits. You will need the county name and its jurisdiction code from the Department of Revenue’s current rate chart.
Exempt sales, separated out. Keep the corresponding Form ST-5 exemption certificates on file for each purchaser claiming tax-free treatment; if an audit later finds a missing certificate, you become liable for the uncollected tax.
Use tax purchases. Any tangible property bought from an out-of-state vendor without Georgia sales tax collected, and then used, stored, or consumed in Georgia, triggers use tax at the same combined state-and-local rate as if the item had been bought in-state.²
Energy sold to manufacturers, which must be reported on a separate line from other taxable sales in each county.

Working Through the Four Parts of the ST-3

The current ST-3, effective for sales beginning October 1, 2022, is available as a PDF from the Department of Revenue.³ Most filers complete it electronically, but the paper form and the online version follow the same four-part structure.

Part A: Tax Summary

Part A is the dashboard. It pulls totals from the other sections and calculates your bottom line.

Line 1: total state sales sourced to Georgia, including leases and rentals.
Line 2: total exempt state sales, including sales exempt from state tax even if subject to local tax.
Line 3: Line 1 minus Line 2, giving your taxable state sales.
Lines 4 through 7: total sales tax from Part B, total use tax from Part B, TSPLOST tax from Part C, and pre-paid local tax on motor fuel from Form ST-3 MF, respectively.
Line 8: total sales and use tax collected per your accounting records for the period.
Line 9: the sum of Lines 4 through 7.
Line 10: Line 8 minus Line 9, which captures any excess tax collected.
Line 11: vendor’s compensation from Part D.

Part B: Sales Tax and Use Tax Distribution

Part B is the county-by-county breakdown, and it trips up more filers than any other section. For each county where you made taxable sales, enter the county name, jurisdiction code, taxable sales amount, and the applicable combined local tax rate, then multiply to get the tax. Lines 13 through 19 handle most filers; if you sell into more than seven jurisdictions, attach additional ST-3 Addendum Sales pages.³

The use tax portion of Part B works the same way, except purchases are reported by the jurisdiction of use: the county where the item was first used in Georgia, not where it shipped from. Each use tax entry needs a reason code:⁴

Code 01, Georgia Use: local tax only, where an item was purchased tax-paid in Georgia but used in a county with a higher local rate.
Code 02, Withdrawal from Inventory: local tax only, where you pulled items from inventory for your own use.
Code 03, Import-Use: state tax only, using state jurisdiction code 000.
Code 04, Import-Use: local tax only.

One common mistake: reporting TSPLOST in Part B. Transportation local option sales tax belongs in its own section.

Part C: TSPLOST Sales and Use Tax

If any of the counties you sell into have an active TSPLOST, report those taxable sales and the corresponding tax in Part C. The structure mirrors Part B (county name, jurisdiction code, taxable amount, rate, tax), but the rates and codes are different. The Department of Revenue’s current rate chart shows which counties have an active TSPLOST and at what rate.

Part D: Vendor’s Compensation

Georgia lets dealers who file and pay on time keep a percentage of the tax collected as compensation for the cost of collecting it. The discount is authorized under O.C.G.A. § 48-8-50, and the regulation confirms that quarterly and annual filers receive it on the same basis as monthly filers.⁵ The compensation is 3% of the first $3,000 in combined state and local tax due, plus 0.5% of any amount above that. You only qualify if you file electronically. Submitting a paper return or payment disqualifies you from the discount for that period. Calculate the amount in Part D and carry it to Part A, Line 11, where it reduces your remittance.

Submitting the Return Through the Georgia Tax Center

The Georgia Tax Center (GTC) is the standard filing method. Log in, select your sales and use tax account, and choose the return period. You can key the figures in directly or, for high-volume businesses, upload a formatted file.⁶ After entering your data, review the totals and submit. Save the confirmation number the system generates. That is your proof of filing.

Paper filing is available only in limited circumstances, typically with authorization from the Department. If you do file by mail, use the ST-3 PDF with the PV-ST payment voucher and send both to the Department of Revenue’s Atlanta processing address. Certified mail gives you a delivery record if a deadline is ever disputed.

Paying the Tax

Georgia accepts ACH debit, ACH credit, credit or debit card, and paper check with the PV-ST voucher. Any dealer owing more than $10,000 on a single return must pay by electronic funds transfer.⁷ That threshold is per return, not an annual total, so a dealer who normally owes $8,000 per month but hits $11,000 in December must use EFT for that filing. Once you cross the threshold and register for EFT, Georgia requires you to continue using it for all future payments of that tax type, even if later amounts drop below $10,000.⁸

Deadlines and the Estimated Payment Rule

For most dealers, the ST-3 is due monthly. Returns and payments are timely if postmarked by the 20th day of the month following the close of the reporting period.⁹ January sales are due February 20, February sales March 20, and so on. The Department of Revenue may authorize quarterly or annual filing on written request, under Ga. Comp. R. & Regs. r. 560-12-1-.22.¹⁰

Larger dealers face an added step. If your state sales tax liability in the preceding calendar year exceeded $60,000 (excluding local taxes), you must remit at least 50% of your estimated tax liability for the current period by the 20th, before the full return is even due. That estimated payment is credited against the amount shown on your completed return.⁹ Missing it is a separate compliance problem on top of whatever happens with the return.

If You File Late or Pay Short

Georgia imposes a penalty of 5% of the tax owed or $5, whichever is greater, for the first 30 days a return is late or tax is unpaid. Another 5% or $5, whichever is greater, accrues for each additional 30-day period. The maximum penalty for a single violation caps at 25% of the tax or $25, whichever is greater.¹¹ Even a zero-dollar return filed late triggers at least a $5 penalty per 30-day block.

Interest runs on top. Georgia charges interest on past-due tax at an annual rate equal to the federal Reserve prime rate plus 3%, reviewed and potentially adjusted each January. It accrues monthly from the date the tax was due until it is paid.¹² Over a few months, penalty and interest together can turn a modest balance into a much larger one. Georgia regulations also authorize the Department to revoke the certificate of registration of any dealer who fails to file required returns.¹³

Fixing a Return After You File It

If you catch an error after submitting, file a corrected ST-3 with the “Amended Return” box checked. The amended return replaces the original rather than supplementing it, so include both the corrected figures and any unchanged information.¹ If the amendment increases the tax owed, pay the difference promptly to limit additional interest and penalty. If it reduces what you owed, the amended return starts the refund or credit process.
