Guides a Georgia business through sales and use tax compliance: nexus determination, registration on GTC, preparing and filing Form ST-3 (or ST-3A for amended returns), collecting and remitting at the correct combined state (4%) and local rate (up to 8%), and handling exemption certificates. Covers economic nexus thresholds, destination-based sourcing, and common audit-risk categories such as SaaS and grocery food.
Determine whether the business has physical or economic nexus with Georgia under O.C.G.A. §48-8-2 and the economic nexus rule (more than $100,000 in Georgia sales OR 200 separate transactions in the current or prior calendar year). If nexus exists and the business is not yet registered, walk through registration on the Georgia Tax Center (GTC) portal at gtc.dor.ga.gov to obtain a Georgia Sales Tax Certificate of Registration.
Identify the correct combined state and local rate for each county where sales are sourced. Georgia is destination-based: the rate is determined by the delivery address of the customer. State rate is 4%; local rate varies by county from 2% to 4%, making the maximum combined rate 8%. Classify all product and service lines as taxable, exempt, or uncertain — paying special attention to Georgia-specific exemptions and grey areas.
Collect and validate Georgia exemption certificates for any customers claiming resale, manufacturing, or other statutory exemptions. Georgia accepts the Streamlined Sales Tax exemption certificate format as well as state-specific certificates. Ensure certificates are current, correctly completed, and retained on file — the burden of proof shifts to the seller if a certificate is missing or defective.
Compile gross sales, deductions for exempt sales, and taxable sales by county to compute the tax due for the filing period. Georgia Form ST-3 (Sales and Use Tax Return) is filed monthly, quarterly, or annually depending on the business's average monthly tax liability. Liability under $200/month qualifies for annual filing; $200–$600/month for quarterly; over $600/month for monthly filing. Use-tax obligations on untaxed purchases used in Georgia must also be self-assessed on the same return.
File Form ST-3 electronically via the Georgia Tax Center (GTC) by the due date — the 20th of the month following the end of the reporting period. Payment is due at the same time. Timely filers are entitled to a vendor compensation discount of 3% of the first $3,000 of tax due plus 0.5% of the excess, capped at $3,000 per period under O.C.G.A. §48-8-50. Late filing triggers a 5% penalty per month up to 25%, plus interest at the prime rate plus 3% under O.C.G.A. §48-2-40.
