Georgia Manufacturing Sales Tax Exemption: Rules and Certificates

Georgia’s manufacturing sales tax exemption lets qualifying manufacturers buy machinery, equipment, repair parts, industrial materials, packaging supplies, and most energy free of state and local sales and use tax under O.C.G.A. § 48-8-3.2.¹ To claim it, you complete Form ST-5M and give it to your supplier before the purchase, not to the Department of Revenue. The state rate alone is 4%, and local rates typically add 1% to 4% on top, so the exemption moves real money on every invoice.

Who Qualifies as a Manufacturer

Georgia defines manufacturing as using physical or chemical means to change industrial materials into tangible personal property with a different form, composition, or character.¹ Turning raw steel into brackets qualifies. Receiving finished brackets, storing them, and shipping them out unchanged does not.

Your business meets the manufacturer test in one of two ways. The clean path is classification under the 2007 North American Industry Classification System in Sectors 21, 31, 32, or 33, or under industry code 22111 (electric power generation) or 511110 (newspaper publishers).¹ The alternative is that your operation is “generally regarded” as manufacturing. That second path is more subjective and more likely to draw scrutiny, so keep detailed documentation of how your process transforms raw materials.

The statute treats manufacturing as one continuous process, from the moment industrial materials arrive at the plant through the completion of packaging.¹ Activities after that — warehousing finished goods for distribution, for example — sit outside the exemption. That boundary matters if your facility handles both production and pure logistics.

What Purchases the Exemption Covers

Every qualifying purchase must be “necessary and integral” to manufacturing. Within that standard, the statute breaks purchases into a few categories.

Machinery and Equipment

Machinery and equipment used directly in production are exempt from all state and local sales and use taxes. Equipment is defined broadly to cover durable devices designed for long-term or repetitive use, plus consumable supplies. The statute names hand tools, molds, dies, jigs, conveyors, pallets, safety devices, and pollution control devices. Machinery that conditions air or water to create the environment production requires — climate control on the factory floor, water treatment systems — qualifies as well.¹

Safety apparel is treated as necessary and integral to manufacturing, including gloves, earplugs, facemasks, protective eyewear, hard hats, breathing apparatuses, and headlamps.

Repair and Replacement Parts

Parts used to maintain, repair, restore, or upgrade exempt machinery carry the same exemption. The statute specifically covers oils, greases, hydraulic fluids, coolants, lubricants, and interchangeable tooling.¹ Spare parts create a common audit issue: you can buy in bulk under the exemption, but if any of those parts later come out of inventory for a non-manufacturing use, use tax is owed on those items.

Industrial Materials and Packaging Supplies

Industrial materials are the raw inputs that become part of the finished product or are consumed during production. This includes components incorporated into the product and materials that coat or impregnate the product at any stage, even when they don’t remain in the finished good. Packaging supplies used at the manufacturing plant fall under the exemption too. Both categories are exempt from all state and local sales and use taxes with no carve-outs.¹

Pollution Control Equipment

Pollution control, sanitizing, sterilizing, and recycling machinery qualifies as manufacturing equipment.¹ Air scrubbers, water treatment systems, and recycling equipment your facility needs to operate fall within the exemption.

Energy

Energy used at a manufacturing plant is exempt when it’s necessary and integral to manufacturing. That covers electricity, natural gas, oil, solid fuel, steam, water, and similar inputs, whether used to run machines, create production conditions, heat and cool the plant, light the facility, or provide personal comfort for employees, as long as it’s consumed at the plant.¹

One carve-out: energy used in manufacturing remains subject to the 1% sales and use tax levied for educational purposes under Georgia’s constitution.¹ The 4% state rate and most local taxes drop off; the education tax still applies. Manufacturers primarily engaged in producing electricity for resale are excluded from the energy exemption entirely.

How to Claim the Exemption

Two forms handle the claim, and they do different jobs.

Form ST-5M is the Certificate of Exemption for Manufacturer.² This is the form you complete and give to your vendor so they don’t charge sales tax on the transaction. You’ll need your business’s legal name as registered with the Georgia Secretary of State, the physical address of the manufacturing facility, your Federal Employer Identification Number, and your Georgia Sales and Use Tax Number. The form also asks for a description of the property being purchased and how it connects to your manufacturing process. Use the specific product names from your equipment documentation rather than generic descriptions; it reduces questions from both the vendor and auditors.

Form ST-M1 is the Application for Certificate of Exemption to Purchase Machinery for New or Expanded Industry.³ If you need a state-issued certificate to prove manufacturing status to vendors — typical when you’re new or expanding into a new facility — this application triggers that certificate. Current versions of both forms are on the Georgia Department of Revenue website.

Whoever signs must be authorized to certify the accuracy of the claims. Using a certificate fraudulently or claiming an exemption you aren’t entitled to is a misdemeanor under O.C.G.A. § 48-1-7, punishable by a fine of up to $1,000, up to 12 months in jail, or both.⁴⁵

Working the Certificates With Your Vendors

Present the completed ST-5M to your vendor at the point of sale. The vendor keeps it on file to justify why no tax was collected if they’re audited.⁶ A properly executed certificate taken in good faith shields the vendor from liability for uncollected tax. If the Department of Revenue later finds the certificate invalid, the burden shifts to the buyer.

Issue a fresh certificate whenever you start with a new supplier or when your business details change: a new facility address, a different tax ID, or a change in the types of exempt purchases you make. Stale or inaccurate certificates are one of the most common triggers for audit adjustments, and they’re entirely avoidable.

Records and Audit Window

Georgia requires dealers to keep exemption certificates and supporting documentation for at least three years following each taxable transaction.⁶ The Department of Revenue normally has three years from the date a return is filed to assess additional tax.⁷ If no return was filed, or the return was fraudulent, there’s no time limit; the Department can assess indefinitely.

Keep copies of every ST-5M you issue, along with invoices showing the exempt purchases and documentation tying those purchases to your manufacturing process. Auditors look for a clear connection between each purchase and the production floor. Administrative office furniture, general-purpose vehicles used off the plant, and supplies for non-manufacturing activities don’t qualify, and claiming them creates exposure across your other certificates.

Penalties for Misuse

The financial consequences go beyond simply repaying the tax you should have collected. Under O.C.G.A. § 48-8-66, late payment penalties start at 5% of the tax due (or $5, whichever is greater) for the first 30 days, with another 5% (or $5) for each additional 30-day period. The penalty caps at 25% of the tax due or $25, whichever is greater.⁸ Interest accrues on top. For willfully fraudulent returns, the penalty jumps to 50% of the tax due, above the standard cap.

The bigger risk for most manufacturers isn’t intentional fraud. It’s careless overreach: claiming the exemption on purchases that serve both manufacturing and non-manufacturing purposes without allocating, or leaving an outdated certificate in place with the wrong facility on it. A single audit finding on one purchase often prompts a deeper review of every exemption you’ve claimed. Getting the classification right up front and keeping your certificates current is the simplest way to keep one problem from becoming several.
