How to Verify a Resale Certificate in Every State: 2026 Guide

Last reviewed: August 14, 2026

Selling products to another business for resale can qualify as a tax-exempt transaction. However, the seller must generally obtain appropriate documentation showing that the purchaser is buying the products for resale rather than for its own use.

Accepting a resale certificate without reviewing it can expose a business to unpaid sales tax, penalties, and interest during a state audit. The seller—not only the purchaser—may be asked to prove why sales tax was not collected.

The safest approach is to confirm that:

• The resale certificate is complete.

• The buyer’s sales tax account or permit is active.

• The purchaser’s business information matches state records.

• The products being purchased are reasonably connected to the buyer’s business.

• The certificate is acceptable in the state where the transaction is taxable.

• Evidence of the verification is retained with the transaction records.

A state’s online system normally confirms that a permit or registration number is active. It does not automatically prove that every purchase made by that business qualifies for resale.

What Is a Resale Certificate?

A resale certificate is a document provided by a purchaser to a seller when the purchaser intends to resell the products being purchased.

The certificate allows the seller to complete the qualifying transaction without collecting sales tax. The purchaser will ordinarily collect the applicable tax when the product is later sold to the final consumer.

Depending on the state, the document may be called a:

• Resale certificate

• Certificate of resale

• Sales tax exemption certificate

• Reseller permit

• Wholesale certificate

• Non-Taxable Transaction Certificate

• Streamlined Sales Tax Exemption Certificate

A resale certificate is not always the same thing as a sales tax permit.

The sales tax permit or registration is issued by a state tax authority and identifies the purchaser as a registered business. The resale certificate is the document the purchaser gives to the seller to support a particular exempt transaction or an ongoing series of purchases.

Who Is Responsible for Verifying the Certificate?

The seller is responsible for documenting why sales tax was not collected.

A buyer may provide a legitimate sales tax number, but the certificate can still be invalid if it is incomplete, outdated, used for the wrong type of purchase, or unacceptable in the applicable state.

A properly completed certificate accepted in good faith can provide important protection to the seller. For example, California regulations recognize good-faith acceptance when a certificate contains the required information and appears valid on its face.

Seven Steps for Verifying a Resale Certificate

1. Obtain the correct certificate

Determine whether the state requires a state-specific form, accepts a multistate form, or permits a purchaser-created certificate containing the required information.

Do not assume that a sales tax license, business registration, W-9, or federal EIN is a substitute for a resale certificate.

2. Review all required fields

Confirm that the certificate contains the purchaser’s legal name, address, tax identification number, exemption reason, product description, date, and signature when required.

Some states, including Florida, may not require the purchaser to sign the state-issued certificate. Always follow the rules of the applicable state rather than applying one checklist universally.

3. Match the certificate to the purchaser

Compare the certificate with the customer’s:

• Purchase order

• Invoice information

• Billing address

• Shipping address

• Business website

• State registration

• Legal business name

Minor formatting differences may be explainable. A completely different business name, address, or entity should be investigated.

4. Verify the permit or account number

Use the state tax department’s official verification system whenever one is available.

Confirm that the registration is active and that the registered business name reasonably matches the purchaser.

5. Confirm that the purchase makes sense for resale

The items purchased should be consistent with the purchaser’s business.

For example, a clothing retailer buying inventory for resale may present a reasonable exemption claim. The same retailer claiming that office furniture, computers, or cleaning supplies are being purchased for resale should receive additional scrutiny.

6. Save evidence of the verification

Retain:

• The completed certificate

• A PDF or image of the certificate

• A screenshot of the state lookup result

• The date of verification

• Any confirmation or authorization number

• Relevant correspondence with the purchaser

• Invoices covered by the certificate

7. Reverify periodically

Reverify a certificate when:

• The certificate expires.

• The buyer changes its legal name or address.

• The purchaser changes ownership or entity type.

• The permit becomes inactive.

• The nature of the products purchased changes.

• A blanket certificate has remained on file for several years.

• The state issues certificates annually.

State-by-State Resale Certificate Verification Directory

The following directory identifies the principal official verification resource or review method available in each state and the District of Columbia.

State systems, forms, and portal menus may change. Always confirm the current instructions with the applicable Department of Revenue before relying on a certificate.

The directory above includes the portal and form structure generally available as of the review date. State agencies may rename portals, modify access requirements, or change whether searches are publicly available.

Special Rules for Florida Resale Certificates

Florida businesses registered to collect sales and use tax receive a Florida Annual Resale Certificate for Sales Tax, Form DR-13.

Florida Annual Resale Certificates expire on December 31 and are issued again for the following calendar year to eligible registered dealers. A certificate from a prior year should not be accepted for transactions occurring in the new year.

Florida sellers can document a sale for resale in several ways.

Method 1: Keep a copy of the certificate

The seller may obtain and retain a paper or electronic copy of the purchaser’s current Annual Resale Certificate.

Florida instructs sellers using this method to maintain the certificate copy for three years.

Method 2: Obtain a transaction authorization number

The seller may verify the purchaser’s certificate for a particular transaction and retain the transaction authorization number instead of keeping a certificate copy.

Method 3: Obtain an annual vendor authorization number

For regular customers, sellers may use Florida’s batch-verification process to obtain an annual vendor authorization number.

The verification file and authorization results should be retained with the seller’s records.

A Florida resale certificate cannot be used to purchase furniture, computers, office supplies, equipment, or other items that the purchaser will use rather than resell. If an item is purchased tax-free for resale but is later consumed or used by the business, Florida use tax may become due.

Can You Accept an Out-of-State Resale Certificate?

Do not assume that a certificate issued by one state is automatically valid in another.

There are several possible situations:

• The state may require its own state-issued certificate.

• The state may allow an out-of-state purchaser to complete the destination state’s form.

• The state may accept a Streamlined Sales Tax certificate.

• The state may accept the Multistate Tax Commission certificate with limitations.

• The purchaser may need to be registered in the state.

• Special rules may apply to drop shipments.

• The certificate may be acceptable only if a particular state registration number is included.

For example, New York states that an exemption certificate issued by another state or country cannot, by itself, establish exemption from New York sales and use tax. A qualified out-of-state purchaser may still be able to use the appropriate New York form under New York’s instructions.

Florida’s treatment also depends on the transaction and the purchaser’s status. The MTC multijurisdiction certificate generally requires a Florida sales and use tax registration number when used to support a Florida resale transaction.

The safest rule is to review the instructions for the specific state and form rather than relying solely on the location where the purchaser is registered.

Streamlined Sales Tax Exemption Certificate

The Streamlined Sales Tax Governing Board provides a uniform exemption certificate accepted by its 24 member states.

The member states are:

• Arkansas

• Georgia

• Indiana

• Iowa

• Kansas

• Kentucky

• Michigan

• Minnesota

• Nebraska

• Nevada

• New Jersey

• North Carolina

• North Dakota

• Ohio

• Oklahoma

• Rhode Island

• South Dakota

• Tennessee

• Utah

• Vermont

• Washington

• West Virginia

• Wisconsin

• Wyoming

Using the SST certificate does not eliminate the seller’s duty to review the purchaser’s information and comply with state-specific instructions.

Multistate Tax Commission Resale Certificate

The Multistate Tax Commission provides a Uniform Sales & Use Tax Resale Certificate—Multijurisdiction.

According to the MTC, 36 states have indicated that the form may be used as a resale certificate. However, each participating state can impose its own requirements and limitations.

A seller should review the instructions printed on the current version of the certificate, including:

• Whether the state accepts the form

• Whether the purchaser must be registered in that state

• Which tax identification number must be entered

• Whether the form is accepted for drop shipments

• Whether additional documentation is required

The MTC recommends contacting the applicable state revenue department when there is uncertainty about acceptance.

Information a Valid Resale Certificate Should Contain

Requirements vary, but a resale certificate will commonly include:

• Purchaser’s legal name

• Purchaser’s business address

• Seller’s name and address

• State sales tax permit or registration number

• State that issued the number

• Type of business operated by the purchaser

• Description of the products being purchased

• Statement that the property is being purchased for resale

• Exemption reason

• Date the certificate was prepared

• Purchaser’s signature or electronic certification, when required

• Indication of whether the certificate applies to one purchase or continuing purchases

A certificate that is missing a material field should be corrected before the seller completes the transaction without charging tax.

Red Flags Sellers Should Investigate

A seller should request clarification or replacement documentation when:

• The business name does not match the state registration.

• The permit is inactive, revoked, canceled, or not found.

• The purchaser provides only an EIN or W-9.

• The certificate is from the wrong state.

• The form is unsigned when a signature is required.

• The document contains obvious alterations.

• The state agency’s name is misspelled.

• The certificate contains a future effective date.

• The purchaser refuses to describe the products being resold.

• The purchase appears unrelated to the buyer’s business.

• The buyer requests tax removal after completing the purchase but cannot provide contemporaneous documentation.

• The purchaser uses a certificate belonging to a parent, subsidiary, affiliate, prior owner, or different legal entity.

• The certificate expired before the sale.

• The shipping address creates a different state tax issue than the billing address.

A red flag does not necessarily mean that the customer is committing fraud. The purchaser may have supplied an old certificate, recently changed its legal name, or registered under a different trade name.

The seller should nevertheless resolve the discrepancy before treating the transaction as exempt.

What to Do When Verification Fails

When a permit cannot be verified:

1. Check the number for typing errors.

2. Confirm that the correct state and portal were used.

3. Ask the purchaser for an updated certificate.

4. Request a copy of the purchaser’s state sales tax registration.

5. Compare the legal name and address with the state record.

6. Contact the applicable state revenue agency if necessary.

7. Document each verification attempt.

8. Charge sales tax if the purchaser cannot establish that the transaction qualifies for exemption.

Do not alter the certificate on behalf of the purchaser. Corrections should ordinarily be completed or authorized by the buyer.

Blanket Resale Certificates

A blanket resale certificate covers an ongoing purchasing relationship rather than a single invoice.

Blanket certificates reduce paperwork but create additional risk because numerous transactions may rely on the same document.

Businesses using blanket certificates should:

• Identify which customer account is covered.

• Associate all exempt invoices with the certificate.

• Review whether every product category purchased qualifies.

• Monitor certificate expiration dates.

• Reverify the purchaser’s permit periodically.

• Replace the certificate when the buyer’s information changes.

• Prevent employees from applying the certificate to personal or nonqualifying purchases.

How Long Should Resale Certificates Be Retained?

There is no universal retention period for every state.

The certificate and verification documentation should be retained for at least the period during which the state can audit the transaction. Some states require longer periods than others, especially when a return was not filed or fraud is alleged.

A practical certificate file should include:

• Original certificate

• Verification screenshot

• Verification date

• Authorization number

• Customer account number

• Invoices covered

• Renewal or expiration date

• Correspondence about discrepancies

• Replacement certificates

Businesses operating in multiple states should establish a retention policy based on the longest applicable state requirement rather than automatically destroying certificates after three or four years.

Create a Repeatable Verification Process

Businesses that regularly make exempt sales should establish a written procedure for collecting and validating resale certificates.

The procedure should define:

• Who reviews certificates

• Which state portal should be used

• What information must match

• How screenshots are saved

• How certificates are connected to customer accounts

• When expired certificates are blocked

• When sales tax must be charged

• Who approves exceptions

A consistent verification process is easier to defend during an audit than informal decisions made separately by individual employees.
