To get a certificate of exemption, figure out which exemption you qualify for, then apply through the right authority: for most sales tax exemptions that means downloading your state’s form and self-certifying, and for nonprofit exemptions it means first obtaining 501(c)(3) recognition from the IRS and then applying to your state. The specifics, fees, and wait times depend on which path fits you.
Figure Out Which Certificate You Need
The application you file depends on why you’re claiming the exemption. Most buyers fall into one of five groups.
- Resale. You’re buying goods to resell to customers, and you don’t want to pay sales tax on inventory that will be taxed again when it reaches the end consumer.1Multistate Tax Commission. Uniform Sales and Use Tax Resale Certificate – Multijurisdiction
- Nonprofit. You represent a charity, school, religious organization, or similar group with recognized tax-exempt status, and the purchases are tied to your exempt purpose.
- Manufacturing or industrial. You’re buying raw materials, machinery, or production equipment that will go into a finished product later subject to sales tax.
- Agricultural. You’re a farm or agricultural business buying equipment, seeds, feed, or fertilizer used directly in production.
- Government. You’re a federal, state, or local agency, generally exempt but often required to hand vendors documentation.
Match yourself to one of these before you start filling anything out. The wrong certificate is worse than no certificate, because it looks like you tried to claim an exemption you weren’t entitled to.
Applying for a State Resale or Sales Tax Exemption Certificate
For resale and most other state sales tax exemptions, the process is short. You’ll need a registered business with a valid seller’s permit or sales tax ID number from your state before you begin.1Multistate Tax Commission. Uniform Sales and Use Tax Resale Certificate – Multijurisdiction
From there:
- Download the appropriate exemption or resale form from your state’s department of revenue website.
- Fill in your business details, your sales tax registration number, and a description of the type of goods you’ll be buying.
- Sign and date the certificate.
- Give the completed form directly to the vendor before or at the time of purchase.
Most states charge no fee and require no government approval step before you hand the form to a seller. You’re self-certifying your eligibility, which is what makes the misuse penalties serious. If you tell a seller goods are for resale and then keep them for your own use, you owe use tax directly to your state.1Multistate Tax Commission.

Manufacturing and agricultural exemptions use the same basic process but layer on documentation requirements. You’ll generally need to show that the items you’re buying are used directly in the exempt production process, not for office supplies or other general business needs.
Applying for Nonprofit Exemption
Nonprofits face a two-step process: federal recognition first, then state exemption. Skipping to the state application without federal status won’t work in most jurisdictions.
Step 1: Get 501(c)(3) Recognition From the IRS
To qualify, your organization must be structured and operated exclusively for charitable, educational, religious, or similar exempt purposes.2Internal Revenue Service. Exemption Requirements – 501(c)(3) Organizations Before you apply, gather your governing documents (articles of incorporation or trust instrument), an Employer Identification Number, and information about your planned activities and finances.3Internal Revenue Service. Before Applying for Tax-Exempt Status
You’ll file Form 1023 for the full application or Form 1023-EZ if your organization qualifies as a smaller entity.4Internal Revenue Service. How to Apply for 501(c)(3) Status Both forms must be filed electronically through Pay.gov.5Internal Revenue Service. Applying for Tax Exempt Status
Filing fees are $600 for Form 1023 and $275 for Form 1023-EZ.6Internal Revenue Service. Frequently Asked Questions About Form 1023 Processing times track the complexity: the IRS issues 80% of Form 1023-EZ determinations within about three weeks, while 80% of full Form 1023 applications take around six months.7Internal Revenue Service.

When approved, the IRS sends a determination letter confirming your status.8Internal Revenue Service. Exempt Organizations Rulings and Determinations Letters Hold onto it. You’ll need it next.
Step 2: Apply for State Sales Tax Exemption
Most states then require a separate application for a state sales tax exemption certificate, using the IRS determination letter as supporting documentation. Requirements and forms vary by state, so check with your state’s department of revenue for the specific application.
If You Buy Across Multiple States
Filing separate certificates for every state you purchase in is tedious, and two shortcuts exist.
The Multistate Tax Commission publishes a Uniform Sales and Use Tax Resale Certificate accepted by 36 states as a valid resale certificate.9Multistate Tax Commission. Uniform Sales and Use Tax Resale Certificate One form, one signature.
The Streamlined Sales Tax Agreement offers its own exemption certificate accepted by every SST member state, and you don’t need to register through the SST system to use it. For sellers in SST member states, presenting the certificate means they should not collect sales or use tax on that transaction, and in most SST states they aren’t even required to verify your ID number.10Streamlined Sales Tax.

Using the Certificate Once You Have It
Hand your completed certificate to the vendor before or at the time of purchase. For a one-time transaction, a single certificate covering that purchase is enough. For repeat purchases from the same supplier, most states allow a blanket exemption certificate that stays on file and covers all qualifying future purchases. This is what businesses typically use with regular wholesalers.
Keep copies of every certificate you issue, plus records of all tax-exempt purchases. If a state auditor questions why you didn’t pay sales tax on a transaction and you can’t produce the certificate, you’ll owe the tax plus penalties and interest.
Expiration and Renewal
Whether your certificate expires depends on which state issued it. Some states set certificates to expire after one year. Others allow them to remain valid for up to ten years, or indefinitely as long as the information is still accurate and there’s an ongoing business relationship between buyer and seller. A few states issue project-specific certificates that expire when the project is complete. Check your state’s rules and calendar the renewal date so a lapsed certificate doesn’t cost you the exemption.
Where the Certificate Doesn’t Protect You
An exemption certificate isn’t a blanket pass on sales tax. It only covers purchases that actually qualify for the exemption you claimed. The most common misuse isn’t dramatic: a business owner buys something with a resale certificate but uses it in the office instead of reselling it. That triggers a use tax obligation you’re supposed to self-report and pay to your state.
States treat deliberate misuse as fraud. Consequences vary by jurisdiction but commonly include owing all unpaid tax plus interest backdated to the original purchase, a penalty of 10% to 25% on top of the tax owed, and in egregious cases, criminal charges. Sloppy paperwork causes assessments too. Missing signatures, missing dates, wrong exemption types, or a name and address that doesn’t match the actual buyer can void an otherwise legitimate exemption. Fill the certificate out completely, and if you end up consuming goods you bought tax-free, pay the use tax voluntarily rather than waiting for an auditor to find it.
