What Is an Ohio Sales Tax Exemption Certificate?
An Ohio sales tax exemption certificate is a document a buyer gives a seller to make qualifying purchases without paying Ohio sales tax. The seller keeps it as audit proof. Ohio’s state sales and use tax rate is 5.75% under Ohio Revised Code (ORC) 5739.02, and local county and transit rates add up to 2.25% on top.
You never file the certificate with the state. You hand it to the vendor, who retains it as the defense for not charging tax. Ohio exemptions are codified in ORC Chapter 5739 (sales tax) and Chapter 5741 (use tax). Ohio is a full member of the Streamlined Sales and Use Tax Agreement (SSUTA), so it also accepts a multistate certificate. Combined rates and local rules for each county are covered in the Commenda Ohio sales tax guide.
Who Qualifies for Ohio Sales Tax Exemption?
Ohio grants exemptions to buyers who use their purchases in a qualifying way, not to buyers by name. Resellers, manufacturers, 501(c)(3) nonprofits, farmers producing for sale, government entities, and contractors on exempt-entity projects all qualify. The exemption reason, not the buyer’s title, controls. Every category below is enumerated under ORC 5739.02(B).
| Exemption category | Who qualifies | Form used | Statutory basis |
|---|---|---|---|
| Resale | Wholesalers, retailers, online resellers buying goods to resell | STEC B or STEC U (reason: resale) | ORC 5739.02(B), tax.ohio.gov |
| Manufacturing | Producers using machinery directly in continuous production for sale | STEC B or STEC U (reason: manufacturing) | ORC 5739.011 |
| Nonprofit / charitable | 501(c)(3)s, churches, qualifying schools buying for their exempt mission | STEC B (reason: nonprofit) | ORC 5739.02(B) |
| Agriculture | Farmers buying inputs used directly to produce crops or livestock for sale | STEC B or STEC U (reason: agriculture) | ORC 5739.02(B) |
| Government | Federal, state, and Ohio local government purchases | Purchase order or STEC B | ORC 5739.02(B) |
| Contractor (exempt project) | Contractors building for a government or qualifying nonprofit | STEC CC | ORC 5739.02(B) |
What Is the Difference Between Form STEC B and Form STEC U?
Form STEC B is the blanket certificate covering all qualifying purchases from one vendor on a continuing basis. Form STEC U is the unit certificate covering a single transaction. The difference is frequency of use, not exemption type. Both forms, currently revised 7/25 per the Ohio Department of Taxation, can state any exemption reason: resale, manufacturing, agriculture, or nonprofit.
A common mistake labels STEC U the “manufacturing certificate” and STEC B the “resale certificate.” That is wrong. You pick the form based on your purchasing pattern, then write in your reason. Ohio’s full exemption certificate set is below.
| Form | Name | Use case | Source |
|---|---|---|---|
| STEC B | Blanket Exemption Certificate | Ongoing qualifying purchases from one vendor | tax.ohio.gov |
| STEC U | Unit Exemption Certificate | A single one-time qualifying purchase | tax.ohio.gov |
| STEC MV | Motor Vehicle Exemption Certificate | Exempt vehicle title transfers (OAC 5703-9-10) | tax.ohio.gov |
| STEC WC | Watercraft Exemption Certificate | Exempt watercraft/outboard motor titles (OAC 5703-9-25) | tax.ohio.gov |
| STEC CC | Construction Contract Certificate | Contractor buying materials for an exempt-entity project | tax.ohio.gov |
| STEC AG | Agricultural Exemption Certificate | Farm inputs and machinery used in production for sale | tax.ohio.gov |
| STEC DP | Direct Pay Certificate | Approved buyers remitting use tax directly to the state | tax.ohio.gov |
| SSTGB F0003 | Multistate Certificate of Exemption | Out-of-state buyers, accepted by Ohio as an SSUTA member | SSTGB |
How Do You Get an Ohio Sales Tax Exemption Certificate?
Ohio requires no pre-approval or state application to use an exemption certificate. You download the STEC form from the Ohio Department of Taxation, complete it, and give it to your vendor. There is no state issuance step and no “exemption number.” The vendor keeps the completed form on file as audit defense.
- Confirm your exemption reason qualifies under ORC 5739.02.
- Obtain an Ohio vendor’s license if you sell taxable goods, which resale claims generally require (Commenda Ohio sales tax permit guide).
- Choose STEC B for ongoing purchases or STEC U for a single purchase.
- Complete and sign the form.
- Deliver it to the seller at or near the time of sale and keep a copy.
How Do You Fill Out the Ohio STEC B Certificate?
You complete STEC B by naming the vendor, your business, and a specific exemption reason, then signing and dating it. Under Ohio Administrative Code (OAC) 5703-9-03, effective 7/17/2020, a valid certificate needs five data elements: purchaser name and address, vendor license or use tax account number, business type, exemption reason, and signature.
State the reason precisely. “Resale” alone is weak; name the activity, such as “purchased for resale” or “used directly in manufacturing.” The most common completion errors:
- Vague or blank exemption reason (the top audit failure)
- Missing signature or date
- Wrong form for the purchasing pattern
- Missing vendor license number where resale is claimed
Does Ohio Issue a Separate Resale Certificate?
No. Ohio has no stand-alone resale certificate. The resale claim is made directly on STEC B or STEC U by stating resale as the exemption reason. Searchers expecting a distinct “resale certificate” document will not find one in Ohio. The STEC forms cover resale the same way they cover every other exemption category.
An Ohio vendor’s license is generally the prerequisite to legitimately issue resale claims, since you certify intent to resell taxable goods. Out-of-state and online resellers who lack an Ohio license may present a home-state certificate or the multistate SSTGB Form F0003, which Ohio accepts as an SSUTA member state.
How Does the Ohio Manufacturing Exemption Work?
Machinery, equipment, and supplies used primarily in a continuous manufacturing operation to produce tangible personal property for sale are exempt under ORC 5739.011. The property must act directly on the product or move it through production. The claim goes on STEC B or STEC U with manufacturing stated as the reason.
The exempt zone starts when raw materials enter the production process and ends when the finished product is packaged. ORC 5739.011 expressly excludes property used for administration, security, recordkeeping, and storage before or after the manufacturing operation. Pre-production storage, post-production warehousing, and office equipment are generally taxable. This boundary is a frequent audit battleground, so document where each asset sits in the production flow.
Do Nonprofits Qualify for Ohio Sales Tax Exemption?
Qualifying 501(c)(3) organizations, churches, and certain schools can buy tax-free for purchases tied to their exempt mission. Ohio does not issue a “tax-exempt number.” The nonprofit self-certifies on STEC B and keeps its IRS determination letter as supporting evidence. Not every nonprofit qualifies automatically, and mission-unrelated purchases stay fully taxable.
Are Government Purchases Exempt in Ohio?
Yes. Federal, state, and Ohio local government purchases for governmental use are exempt under ORC 5739.02(B), and a purchase order often suffices as documentation.
How Does the Ohio Agricultural Exemption Work?
Seeds, fertilizer, feed, and machinery used directly in producing crops or livestock for sale are exempt in Ohio. Personal and hobby farming do not qualify. The claim is made on STEC B or STEC U (or the STEC AG variant) with agriculture stated as the reason, not on any single “agricultural certificate.”
The real property versus equipment distinction matters. Movable equipment and consumable inputs used directly in production qualify, while items that become part of real property, such as a permanent building, are treated differently and are often taxable. Keep records showing each purchase is used exclusively in qualifying, for-sale farm activity.
When Are Contractors Exempt From Ohio Sales Tax?
By default, contractors are the consumers of materials they incorporate into real property and must pay sales tax on those materials. The main exception is work for an exempt entity, such as a government body or qualifying nonprofit, claimed using the STEC CC construction contract certificate. This is grounded in ORC 5739.02(B).
The consumer-versus-reseller framing drives everything here. A contractor who installs materials is a consumer and owes tax; a contractor who resells materials without installing them may claim resale instead. Misusing a contractor exemption, especially claiming exempt status on a taxable private project, is a high audit risk and triggers assessments for the unpaid tax.
Do Ohio Exemption Certificates Expire?
Ohio blanket certificates carry no statutory expiration date. They become invalid when the buyer’s eligibility, business status, or information changes, so annual review is the practical standard. A properly completed STEC B stays valid as long as the underlying facts remain true and the vendor relationship continues.
Treat renewal as lifecycle management rather than a fixed deadline. Revalidation is triggered by a change of legal entity, address, ownership, exemption reason, or loss of qualifying status, such as a nonprofit losing its 501(c)(3) determination. Re-collecting certificates every one to three years keeps the file defensible when the Ohio Department of Taxation asks for it.
How Do You Validate an Ohio Resale Certificate?
A seller validates a certificate by checking that it is complete, plausible for the buyer’s business, and collected at or near the time of sale. Under OAC 5703-9-03, a fully completed certificate accepted in good faith shifts the tax liability to the buyer. A defective certificate gives the seller no protection and leaves the seller owing the tax.
Confirm each required element is present: buyer name and address, tax ID or vendor license number, a specific exemption reason, and a signature with date. Verify the reason fits the buyer’s line of business; a hardware reseller claiming a manufacturing exemption on office furniture is a red flag. Ohio has no public resale-lookup database, so completeness and good-faith review are the core defense.
How Do You Manage Exemption Certificates for Ohio Audits?
Keep every certificate retrievable on demand, matched to the invoices it covers, and reviewed on a schedule. Under OAC 5703-9-03, Ohio presumes every sale taxable until a valid certificate proves otherwise, and vendors must retain the completed certificate. Missing or defective certificates convert exempt sales into assessable ones with back taxes, penalties, and interest.
Best practices that hold up in an audit:
- Collect the certificate at the point of transaction, before the sale closes.
- Store certificates digitally with retrieval on demand.
- Use e-signatures, valid under state and federal e-signature law.
- Cross-check certificates against invoices in periodic internal reviews.
The consequence mechanism is direct: undocumented exempt sales become assessable liabilities for the seller, not the buyer who claimed the exemption.
