How Do You Fill Out a Resale Certificate Correctly?

To fill out a resale certificate correctly, use the certificate accepted by the state governing the transaction, enter the purchaser’s sales-tax registration information in the proper section, describe what is being bought for resale, identify the seller, and complete the certification with an authorized signature and date. Do not substitute an EIN, a seller’s permit, or a copy of a permit unless the applicable state’s instructions expressly allow the information or document you provide.

The most important first step is identifying which state’s rules apply. There is no single nationwide completion rule: California, Texas, and New York, for example, publish materially different requirements and forms. If your business first needs sales-tax registration, start with the appropriate state sales tax application information. Registration and certificate completion are related, but they are not the same task.

Start with the transaction, not a generic template

A resale certificate documents the purchaser’s claim that the covered property is being acquired for resale rather than for the purchaser’s own use. Before writing anything, answer three questions:

• Which state governs the transaction?
• Are the specific items being purchased for resale?
• Does that state require its own form, permit number, registration number, or particular certification language?

Do not assume a certificate used with one supplier or in one state will work everywhere. The examples from California, Texas, and New York do not establish that any one of those certificates is accepted in another state. Check the instructions for the state involved in the current purchase.

Also distinguish a resale certificate from federal identification. The IRS calls a business’s federal tax identifier an Employer Identification Number, or EIN. IRS EIN confirmation documents include the CP575 Employer Identification Number Verification Notice and Letter 147C, EIN Previously Assigned. Those documents are not identified by the IRS as resale certificates, and an EIN is not a universal resale number.

If the terminology is causing confusion, compare the separate roles explained in seller’s permits and resale certificates. A permit or registration generally identifies the business’s state sales-tax account, while a resale certificate is completed for a purchase being claimed as a sale for resale.

Scenario 1: You are completing a certificate for a routine resale purchase

Suppose a retailer is purchasing inventory from a supplier and expects to resell that inventory in the regular course of business. The purchaser should use the state-approved certificate or another format that the governing state expressly permits. The entries should be internally consistent: the purchaser name should identify the buying business, the seller section should identify the supplier, and the item description should explain what is actually being acquired for resale.

A vague description can make the transaction difficult to evaluate. Instead of merely writing “products” or “merchandise,” describe the category of goods in practical terms. The description of the purchaser’s business should also make sense in relation to the items being purchased. If the form presents different resale categories, select the category that accurately reflects the transaction rather than checking every available option.

The registration field deserves particular attention. Enter the state sales-tax permit or registration number requested by that form, not automatically the EIN. Preserve prefixes, spacing, or other identifying elements shown on the business’s registration record. If the form provides a special section for an out-of-state purchaser, use that section rather than placing an out-of-state number in a field reserved for in-state registrants.

Finally, review the certification language before signing. The person signing should be authorized to certify for the purchaser and should provide every requested element, which may include a printed name, title, signature, and date. Do not sign an incomplete certificate and expect the supplier to determine which purchases are exempt.

Scenario 2: Your purchase includes both resale and business-use items

A mixed purchase requires more care than an inventory-only order. If some items will be resold and others will be consumed, used, installed, or otherwise retained by the purchaser, do not represent the entire order as a resale purchase without confirming that the governing rules support that treatment.

Texas provides a useful example of the required distinction. Texas instructs purchasers buying a mixture of resale and nonresale items to identify clearly which items will be resold. Its blanket-certificate option is limited to customers purchasing exclusively for resale and stating that all purchases will be resold in the regular course of business.

For a mixed order, practical ways to make the intended treatment clear include identifying the resale items by line, using an attached list when the form permits it, or arranging separate orders for resale and nonresale property. The goal is to avoid a certificate that appears to cover property outside the purchaser’s resale claim.

This is also where the distinction between resale and other exemptions matters. A purchase that is not for resale does not become a resale transaction merely because the purchaser believes another exclusion may apply. If the claimed treatment is based on the purchaser’s status or a non-resale use, review the appropriate exemption certificate information instead of placing the transaction on a resale certificate.

Scenario 3: The form asks for unfamiliar registration information

California: seller’s permit number or an allowed explanation

California does not limit a resale certificate to one particular document format. For a California purchase claimed as a sale for resale, a document may serve as the certificate if it contains the purchaser’s business name and address, the seller’s permit number or an explanation of why no permit is required, a description of the property, an express statement that the property is for resale, the date, and an authorized signature.

The California Department of Tax and Fee Administration calls the state registration document a “seller’s permit.” A purchaser that is not required to hold a California seller’s permit may state the reason on the certificate instead of supplying a permit number. That exception should not be read as general permission to omit registration information whenever it is inconvenient; it applies when the purchaser is not required to hold the permit.

Texas: use the number requested on Form 01-339

Texas uses Form 01-339, Texas Sales and Use Tax Resale Certificate. It requests purchaser and seller information, the Texas permit number or a qualifying out-of-state registration number, descriptions of the items and the purchaser’s business, and the purchaser’s signature, title, and date.

The completed Texas form is furnished to the supplier rather than sent to the Comptroller. A Texas permit or a copy of the permit does not substitute for the resale certificate. The seller must retain accepted resale certificates for four years, so the purchaser should provide a complete document that the supplier can keep with its records.

New York: choose the correct purchaser section

New York uses Form ST-120, Resale Certificate. The purchaser selects single-use or blanket status, although a New York temporary vendor must use a single-use certificate. Registered New York vendors enter their valid sales-tax identification number, and temporary vendors also provide its expiration date.

Qualifying non-New York purchasers use the applicable part of Form ST-120 to identify their home jurisdiction and registration number. If their home jurisdiction does not require registration or issue a number, the form instructs them to write “not applicable.” New York also requires the purchaser to identify the business and principal products, choose the applicable resale category, and have an owner, partner, or authorized person print their name and title, sign, and date the certificate. Contractors may not use Form ST-120 to purchase materials and supplies.

These differences show why the state’s instructions—not a supplier’s generic account field or the purchaser’s EIN—should control how an unfamiliar registration question is answered.

Scenario 4: The supplier asks for a blanket certificate

A blanket certificate is intended to address qualifying future purchases from the same seller, while a single-use certificate addresses an individual transaction. Whether blanket treatment is available and what it covers depends on the governing state’s rules and the purchaser’s circumstances.

Before selecting blanket status, consider whether all purchases covered by the certificate will actually qualify for resale treatment. If the business routinely buys both inventory and supplies for its own use from the same seller, a broad blanket statement may not match the purchasing pattern. Use single-use treatment, separate purchasing accounts, or another permitted method when that more accurately identifies the resale transactions.

New York Form ST-120 expressly asks the purchaser to select single-use or blanket status, but temporary vendors are restricted to single-use certificates. Texas permits a blanket certificate when the customer purchases exclusively for resale and states that all purchases will be resold in the regular course of business. Those rules are state-specific and should not be carried over automatically to another jurisdiction.

Final review before giving the certificate to the seller

Use a short accuracy review before submitting the document:

• Confirm that you used the certificate or format permitted for the state governing the transaction.
• Verify the purchaser’s legal or business name and address.
• Enter the requested state permit or registration number in the correct section, or use an expressly permitted explanation when applicable.
• Identify the seller named in the transaction.
• Describe the items being purchased for resale and the purchaser’s type of business with enough specificity to connect the purchase to the resale activity.
• Exclude or clearly distinguish personal-use, business-use, and other nonresale items.
• Select single-use, blanket, or another category only when it fits the transaction and the state’s instructions.
• Read the certification, then provide the requested printed name, title, authorized signature, and date.

A correctly completed certificate should tell a coherent story: who is buying, from whom, under which state registration or permitted exception, what property is being acquired, and why the purchase qualifies as a purchase for resale. If any of those answers conflict, correct the certificate before providing it to the seller. Businesses looking for a broader overview of resale documentation can also review information on resale certificates, wholesale licensing, and sales-tax permits.
