What Are Exemption and Resale Certificates?

Exemption certificates and resale certificates are official documents that allow buyers to legally avoid paying sales tax on qualifying purchases in Ohio. These sales tax exemption certificate in Ohio confirm that the buyer meets the state’s criteria for sales tax exemptions, shifting the responsibility to collect tax onto the seller only when applicable.

• Resale Certificates: Used by wholesalers or retailers who purchase goods for resale. For example, a clothing store buying inventory from a supplier can present a resale certificate to avoid paying sales tax upfront, since the tax will be collected when the clothing is sold to the end customer.

Exemption Types Recognized in Ohio

The Ohio sales tax rate is 5.75% (with additional local rates up to 2.25%), but certain transactions qualify for exemption through the proper use of an Ohio Sales and Use Tax Exemption Certificate (Form STEC B) or specialized certificates. Understanding these exemptions is essential for compliance and avoiding unnecessary tax liabilities.

1. Resale Exemption

It is for merchants purchasing items for resale and not consumption. Businesses purchasing goods for resale can use Form STEC B – Blanket Exemption Certificate (Resale) to avoid paying sales tax at the time of purchase. Sales tax will be collected when the item is sold to the final consumer.

• Vendor’s name and license number
• Purchaser’s name, address, and business type
• Statement of intent to resell
• Signature and date

2. Nonprofit / Charitable Exemption

• Proof of nonprofit status (e.g., IRS determination letter)
• Must purchase goods directly for charitable activities

3. Government Exemption

Requirements:

• Must be in direct use in the manufacturing process
• Supplier may require additional compliance documentation

5. Agricultural Exemption

Exempt items include seeds, fertilizers, and machinery used in the production of crops or livestock. Buyers must complete Form STEC U (Agricultural Exemption Certificate) at the time of purchase.

Requirements:

• Purchases must be used exclusively in qualifying farm activities
• Specific rules apply to real property vs. equipment

6. Construction & Contractor Exemption

Requirements:

• Relies on contract terms and roles (vendor vs. contractor)

State-Specific Requirements for Exemption Certificates in Ohio

When searching for “how do I get an Ohio sales tax exemption certificate,” know that Ohio requires businesses and organizations to provide valid sales and use tax exemption certificates to claim tax-free purchases for qualifying transactions. Unlike states without a sales tax, Ohio strictly enforces documentation requirements to verify exemption eligibility.

Required Information on the Certificate

All Ohio exemption certificates must include:

• Buyer’s name, address, and tax ID (vendor license or FEIN)
• Seller’s name and address
• Detailed description of the goods or services purchased
• Reason for exemption (e.g., resale, manufacturing, agriculture, nonprofit use)
• Buyer’s signature and date of issuance

Accepted Forms and Formats

• Ohio accepts its own state forms (e.g., STEC B, STEC U) for exemption purposes.
• Multi-state exemption certificates (MTC) are accepted for out-of-state vendors if they meet Ohio requirements.
• Certificates must be filled out completely and provided at or near the time of the transaction.

Validity Period and Renewals

• Most Ohio exemption certificates remain valid indefinitely unless there is a change in the buyer’s eligibility or business status.
• Blanket certificates can be used for recurring purchases from the same vendor but should be reviewed annually for accuracy.

Electronic vs. Paper Submission

• Ohio allows exemption certificates to be stored electronically, provided they can be retrieved on demand for audits.
• Digital signatures are valid if they comply with state and federal e-signature regulations.
• Vendors should maintain both electronic and paper copies where feasible for audit readiness.

Common Pitfalls and Compliance Risks

Managing sales tax exemption certificates in Ohio may seem straightforward, but poor oversight can quickly lead to serious compliance risks. Here are the most common pitfalls businesses face:

• Expired or Outdated Certificates: A lot of people ask this question, “do sales tax exemption certificates expire in Ohio?” While Ohio blanket certificates technically don’t expire, changes in buyer information, tax status, or business use can void their validity.
• Incomplete or Incorrect Information: Ohio law requires specific data points on certificates, such as buyer’s name, address, exemption reason, and tax ID. Common errors include missing buyer signatures, incorrect exemption reasons, using the wrong form.
• Accepting Certificates from Ineligible Buyers: Some buyers may wrongly claim exemptions, intentionally or by mistake. For instance, a nonprofit may present an exemption certificate for items not related to its exempt activities.

Scenario Example of Poor Certificate Practices

A mid-sized Ohio wholesaler regularly accepted resale certificates from business clients but failed to implement a verification process. Over time:

• Some certificates were never signed
• A few clients went out of business
• One buyer used a resale certificate for clearly non-resale items (e.g., office furniture)

During a sales tax audit, the Ohio Department of Taxation flagged 17 transactions lacking proper documentation. The company was assessed $68,000 in back taxes, $11,000 in penalties, and forced into a prolonged 6-month audit involving hundreds of other invoices.

Lesson: What could have been avoided with automated certificate tracking and review cost the business significant financial and operational strain.

Best Practices for Managing Exemption Certificates

Now that the answer for what is a Ohio sales tax exemption certificate clear, its important to know that their proper management ensures compliance, minimizes audit risks, and prevents unnecessary tax liabilities. Below are proven strategies Ohio businesses can adopt:

• Collect Certificates at the Point of Transaction: Always obtain the exemption certificate before completing a tax-exempt sale. Delayed collection increases the risk of incomplete or incorrect documentation and may lead to denied exemptions during audits.
• Keep Certificates Updated and Accurate: Even though Ohio blanket certificates don’t expire, buyer details, tax status, or exemption reasons can change. Perform annual reviews to confirm all certificates are still valid.
• Use Digital Storage for Audit-Readiness: Switch from paper files to a secure digital repository. This ensures certificates are easily searchable, backed up and accessible during audits, time-stamped to prove when they were collected.
• Automate Renewal and Verification Reminders: Set up automated systems (e.g., through Commenda) to flag certificates that require updates due to regulatory changes, buyer information changes, or internal policy schedules.
• Conduct Periodic Internal Audits: Schedule quarterly or semi-annual reviews of your exemption certificate records. Cross-check certificates against invoices to ensure compliance and correct tax application.
