In Ohio, a buyer generally documents a qualifying tax-exempt purchase by giving the seller a completed exemption certificate. For goods bought to resell, the buyer claims the resale exemption on the certificate; Ohio does not issue a separate resale-certificate number for a buyer to obtain. The seller should collect and retain the certificate and check that the buyer’s information and stated reason for exemption make sense for the transaction.
Ohio sales tax registration and exemption paperwork are handled through the Ohio Department of Taxation and the Ohio Business Gateway. Ohio also administers a separate Commercial Activity Tax (CAT), so a business may have distinct sales-tax and CAT obligations. This page explains the certificate process; the right treatment can depend on the goods, buyer, and transaction, so confirm uncertain cases with the Department or ask Sales Tax Compliance USA to review them.
How Ohio resale certificates work
A resale certificate is the buyer’s written claim that a purchase is for resale in the ordinary course of business, rather than for the buyer’s own use. The buyer gives the certificate to the seller, who keeps it as support for not collecting sales tax on that sale. It is not a general exemption for everything a business buys: inventory intended for resale may qualify, while equipment, office supplies, and items consumed by the business generally do not qualify merely because the purchaser is a retailer.
Ohio uses exemption certificate forms that cover resale and other exemption reasons. A buyer does not apply to Ohio for a standalone resale-certificate number. The buyer provides its business and vendor-license details, identifies the purchase as resale, and completes the applicable certificate for the seller. A seller should not treat a certificate as proof that every purchase by that buyer is exempt; the stated reason must fit the specific goods and transaction.
Choose the right Ohio exemption certificate form
Ohio’s general certificate forms include STEC B, the blanket exemption certificate, and STEC U, the unit exemption certificate. STEC B is used when a buyer expects to make recurring purchases from a seller that qualify for the exemption stated on the certificate. STEC U documents an exemption for a particular purchase or transaction. The choice is about the scope of the certificate, not a different standard for whether the purchase actually qualifies.
Ohio also provides forms for particular transaction types and exemptions. Use the form that matches the transaction rather than assuming the general certificate covers a special case. For example, Ohio publishes separate forms for certain vehicle and watercraft transactions. Check the current forms and instructions on the Ohio Department of Taxation website before relying on a certificate, since form names and requirements can change.
Who qualifies for an Ohio sales tax exemption
Eligibility depends on the legal basis for the exemption and how the property will be used. A business buying goods for resale may claim the resale exemption when the goods are acquired for resale, rather than for its own use. Other exemptions may apply to qualifying purchases by particular organizations or to property used in specified activities, including certain manufacturing or agricultural uses. A buyer’s business status alone does not make its purchases exempt.
For a seller, the practical test is whether the buyer’s stated exemption fits the item and the transaction. If the buyer claims an exemption that is unclear, incomplete, or inconsistent with the purchase, ask for clarification or supporting details before treating the sale as exempt. The exact position depends on the facts and the current Ohio rules; confirm a doubtful claim with the Ohio Department of Taxation.
Register as an Ohio vendor before making exempt sales
A resale certificate does not replace the buyer’s Ohio vendor registration. A business making taxable retail sales in Ohio generally needs the appropriate vendor’s license or seller’s use tax registration, depending on its circumstances. The Ohio Business Gateway is the state’s online registration system for vendor licensing, and the Department of Taxation provides information for sellers on registration and sales-tax responsibilities.
Ohio-based sellers and sellers located outside Ohio may have different registration routes. Do not assume that a certificate from a buyer authorizes the seller to make sales without the required registration, or that sales-tax registration resolves CAT obligations. Ohio administers CAT separately from sales tax; whether a business has a CAT filing or payment obligation depends on its circumstances. Check both programs with the Department rather than treating one registration as covering both.
Collect and complete certificates before the sale
Obtain the certificate from the buyer and complete the documentation before treating the sale as exempt. The buyer should identify the purchaser and seller, provide the relevant business and vendor-license information requested by the form, select or describe the exemption reason, and describe the covered goods or transactions as required. The buyer or authorized representative should sign and date the certificate where the form calls for it.
For a blanket certificate, make sure its stated scope reasonably covers the purchases being made. For a unit certificate, connect it to the specific transaction and retain the related invoice or order record. If information is missing or the exemption reason does not fit the goods, request a corrected certificate or collect tax unless the buyer establishes a valid basis for exemption. Keep the certificate with the sales records so it can be matched to the transaction later.
Verify exemption certificates and buyer details
Ohio does not provide a separate resale-certificate number that a seller can validate as a standalone credential. A seller can review the certificate for completeness, compare the buyer’s name and business details with the order and account records, and check that any Ohio vendor-license information supplied is consistent with the buyer’s business. The seller should also consider whether the goods are the kind of items the buyer would resell and whether the certificate’s exemption claim fits the sale.
If the buyer’s details cannot be reconciled, contact the buyer for clarification and request a corrected certificate or other appropriate documentation. For a question about a license or a particular exemption, contact the Ohio Department of Taxation. A seller’s review should be documented; a certificate that is signed but materially incomplete or implausible is not a substitute for reasonable transaction records.
Understand Ohio exemptions for manufacturing and agriculture
Ohio has exemptions that may apply to certain property used in manufacturing or agriculture, but the activity label alone does not establish eligibility. The nature of the property, how it is used, and the specific statutory conditions matter. A manufacturer should distinguish qualifying production use from general business use, and an agricultural buyer should distinguish qualifying agricultural use from personal or unrelated use.
Before accepting a manufacturing or agricultural exemption, identify the applicable Ohio exemption and use the certificate or documentation required for that claim. Ask the buyer to explain the intended use when it is not clear from the order. Because the boundary between qualifying and nonqualifying use can be fact-specific, confirm uncertain purchases with the Ohio Department of Taxation rather than extending an exemption based only on the buyer’s industry.
Keep certificates and records ready for an audit
Retain each certificate with the records that show what was sold, when it was sold, who bought it, and why the sale was treated as exempt. Useful supporting records include invoices, order details, customer account information, correspondence resolving questions, and any documentation relevant to the claimed exemption. Organize records so a certificate can be connected to the transactions it covers, especially when using a blanket certificate.
Ohio’s Department of Taxation may examine a seller’s records, so keep them accessible and consistent. Do not rely on a certificate alone when the transaction details contradict the exemption claim. The retention period and any special documentation requirements can depend on the record and applicable rules; check current Ohio Department of Taxation guidance for the period that applies to your records.
Know how long Ohio certificates remain valid
Ohio’s blanket certificate is intended for recurring qualifying purchases, while a unit certificate relates to a particular purchase. Do not assume that a blanket certificate remains appropriate indefinitely if the buyer’s business, exemption basis, or purchasing pattern changes. Review the certificate when those facts change and obtain an updated or transaction-specific certificate when needed.
The exact validity and recordkeeping treatment should be checked against the current Ohio form instructions and Department of Taxation guidance. If you cannot establish that an older certificate still covers the current purchase, request a new certificate before applying the exemption. This avoids relying on a document whose scope or buyer details no longer match the transaction.
Get help managing Ohio exemption certificates
Managing certificates across ecommerce orders can involve more than collecting a form: sellers need to match the exemption reason to the goods, check buyer details, retain supporting records, and revisit certificates when circumstances change. Cross-border sellers may also need to determine whether Ohio registration applies and whether CAT creates a separate obligation. These are related compliance tasks, but a resale certificate does not resolve them all.

How Ohio’s general exemption certificate forms differ in scope, and what sellers should document.
| Ohio form or record | Typical scope | Seller’s practical check |
|---|---|---|
| STEC B — blanket exemption certificate | Recurring purchases from a seller that qualify for the exemption stated on the certificate. | Check that the buyer, exemption reason, and covered purchases fit; revisit it if the buyer’s circumstances or purchasing pattern changes. |
| STEC U — unit exemption certificate | A particular purchase or transaction. | Match the certificate to the specific invoice or order and retain the related transaction record. |
| Special-purpose Ohio certificate | A transaction category with its own Ohio form, such as certain vehicle or watercraft transactions. | Use the current form and instructions for that transaction rather than assuming a general certificate is sufficient. |
| Invoice and supporting records | Evidence connecting the exempt sale to the buyer, goods, and claimed exemption. | Keep records together so the exemption claim can be understood and reviewed later. |
Frequently asked questions
How do I get a resale certificate in Ohio?
Ohio does not issue a separate resale-certificate number. Register for the appropriate Ohio vendor’s license or seller’s use tax account if your business needs one, then give your supplier a completed Ohio exemption certificate claiming resale, such as STEC B for qualifying recurring purchases or STEC U for a particular transaction. Use the current form from the Ohio Department of Taxation.
Does Ohio have a separate resale certificate?
No separate state-issued resale certificate or resale number is required as a standalone credential. Ohio buyers document a resale claim using an exemption certificate provided to the seller. The seller should retain it and confirm that the goods and transaction fit the resale claim.
What form do I use for an Ohio sales tax exemption?
For general exemption claims, Ohio provides STEC B for blanket claims covering qualifying recurring purchases and STEC U for a particular purchase. Some transaction types have their own forms, so check the Ohio Department of Taxation’s current forms and instructions before choosing. The form must match the exemption and transaction.
What is the difference between STEC B and STEC U?
STEC B is a blanket exemption certificate for qualifying recurring purchases from a seller. STEC U documents an exemption for a specific purchase or transaction. Neither form makes an otherwise taxable purchase exempt; the buyer must meet the requirements for the claimed exemption.
Do I need an Ohio vendor’s license to buy goods for resale?
A buyer making taxable retail sales in Ohio generally needs the appropriate vendor registration, but the exact registration depends on the business and its location. The license is not a separate resale-certificate number: the buyer claims resale by giving its supplier a completed exemption certificate. Confirm the correct registration route with the Ohio Department of Taxation or through the Ohio Business Gateway.
How do I fill out an Ohio exemption certificate?
Use the current Ohio form and complete the buyer and seller details, the requested vendor-license or business information, the exemption reason, and the description or scope of the covered purchases. Sign and date it where required, and use a unit certificate for a specific transaction or a blanket certificate only for purchases within its stated scope. Ask the buyer to correct missing or inconsistent information before treating the sale as exempt.
How long is an Ohio resale certificate valid?
A unit certificate applies to the particular transaction it documents; a blanket certificate is intended for recurring qualifying purchases. Do not assume a blanket certificate remains suitable if the buyer’s details, exemption basis, or purchasing pattern changes. Check the current Ohio form instructions for any specific validity or recordkeeping rule that applies.
How can a seller verify an Ohio resale certificate?
Ohio does not provide a separate resale-certificate number to validate. Review the certificate for completeness, compare the buyer’s details with your records, check any license information supplied, and confirm that the goods and transaction fit the resale claim. If anything is unclear, request clarification or a corrected certificate and contact the Ohio Department of Taxation about a specific licensing or exemption question.
