Kentucky Form 51A126 is the Purchase Exemption Certificate that a qualifying nonprofit educational, charitable, or religious institution, or a Kentucky historical site, gives to a vendor to buy tangible personal property, digital property, or services without paying the state’s 6% sales tax.1Kentucky Department of Revenue. Kentucky Form 51A126 – Purchase Exemption Certificate To fill it out correctly you need a Purchase Exemption Number already issued by the Kentucky Department of Revenue, the vendor’s name, and a description of what you’re buying for your exempt function. The completed form goes to the seller, not to the state.
Who Can Use This Form
Eligibility is narrow. Under KRS 139.495, the exemption is available to resident nonprofit educational, charitable, or religious institutions that hold 501(c)(3) status under the Internal Revenue Code, provided the purchase is used solely within the organization’s educational, charitable, or religious function inside Kentucky.2Justia. Kentucky Code 139.495 – Application of Taxes to Nonprofit Educational, Charitable, or Religious Institutions A resident single-member LLC wholly owned by a qualifying 501(c)(3) and treated as a disregarded entity for federal tax purposes qualifies on the same terms.
Kentucky historical sites qualify through a different door: KRS 139.482 covers nonprofits located in Kentucky and listed on the National Register of Historic Places. Across all eligible organizations the same limit applies. The purchase has to serve the exempt function. Office supplies for church operations, yes. A personal gift for staff, no.
Get Your Purchase Exemption Number First
Form 51A126 will not do anything on its own. It requires an exemption number that only the Department of Revenue can issue, and you obtain that by filing Form 51A125, the Application, Update or Cancellation for Purchase Exemption. Supporting documentation depends on your organization type, such as proof of 501(c)(3) status or National Register listing.3Kentucky Department of Revenue. Form 51A125 – Application, Update or Cancellation for Purchase Exemption
You can submit the application three ways:
- By mail to the Division of Sales and Use Tax, PO Box 181, Station 67, Frankfort, KY 40602-0181
- By fax to (502) 564-2041
- By email to DOR.WebResponseSalesTax@ky.gov
If approved, the Department sends a letter of authorization with your Purchase Exemption ID and instructions for claiming the exemption.3Kentucky Department of Revenue. Form 51A125 – Application, Update or Cancellation for Purchase Exemption That ID is the number you’ll enter on every 51A126 from then on.
Filling Out Each Field
The certificate is a single page, and it is not valid unless every field is complete.1Kentucky Department of Revenue. Kentucky Form 51A126 – Purchase Exemption Certificate Work through it in order.
- Exemption Number. The Purchase Exemption ID from your Department of Revenue authorization letter.
- Name of Exempt Institution. Your organization’s full legal name as it appears on the authorization letter.
- Blanket or Single Purchase. Check one box. More on this choice below.
- Institution Certification. Fill your organization’s name and Kentucky address into the certification statement, which confirms you are a Kentucky resident nonprofit educational, charitable, or religious institution, or a Kentucky historical site.
- Vendor Name. The seller you are buying from.
- Description of Property. Describe the tangible personal property, digital property, or services being purchased. Write it specifically enough that an auditor could see the items belong to your exempt function.
- Authorized Signature, Title, and Date. An officer or authorized employee signs. The signature is under penalties of perjury, so the person signing needs actual authority and accurate information.
A blank field is not a minor issue. An incomplete certificate does not qualify as validly issued, and the seller loses the protection it provides.
Blanket or Single Purchase
The checkbox at the top decides how far the certificate reaches. A single-purchase certificate covers one transaction, which is what you want for a one-off buy from a vendor you may not use again. A blanket certificate covers all future qualifying purchases from the same vendor, so you don’t have to fill out a new form each time.1Kentucky Department of Revenue. Kentucky Form 51A126 – Purchase Exemption Certificate
If your organization orders regularly from the same supplier, a blanket certificate on file saves real paperwork. Write the property description broadly enough to cover the categories you typically buy, but keep it tied to your exempt function so it still reads as a legitimate exempt-use description on audit.
Giving the Certificate to the Seller
The completed form goes to the vendor, not to the Department of Revenue. Hand it over in person, mail it, or send it electronically. Under KRS 139.270, the seller must obtain the completed certificate within 90 days of the sale in order to be relieved of the burden of proving the sale was exempt.4Kentucky Legislative Research Commission. Kentucky Code 139.270 – Resale Certificate and Certificates of Exemption Giving it at the time of purchase is cleanest for both sides.
The seller keeps the certificate on file. If the Department later audits the seller and questions the sale, the seller has a second chance to obtain a completed certificate from the purchaser within 120 days of the Department’s request, as long as the exemption was actually available and reasonable for that type of organization.4Kentucky Legislative Research Commission.

When the Form Does Not Apply
One boundary catches organizations off guard. Construction contractors cannot use Form 51A126 to buy materials for a contract with an exempt institution. The form says so on its face, and any seller who accepts a certificate for that purpose is held liable for the tax.1Kentucky Department of Revenue. Kentucky Form 51A126 – Purchase Exemption Certificate If a contractor builds an addition to your church, the contractor pays sales tax on the building materials. Your exemption does not pass through to their purchases.
Keeping the Exemption Clean
If property bought with the certificate ends up used for a non-exempt purpose, the buyer owes the tax on the purchase price.1Kentucky Department of Revenue. Kentucky Form 51A126 – Purchase Exemption Certificate An official or employee who uses the certificate for personal purchases faces penalties under KRS 139.990.
The Department’s civil penalty structure adds real cost on top of the tax:5Kentucky Department of Revenue. Penalties, Interest and Fees
- Negligence: 10% of the tax assessed, no cap.
- Late payment or failure to collect tax: 2% of the tax due for each 30-day period or fraction of one, capped at 20%.
- Fraud: 50% of the tax assessed, no cap or minimum.
Because you sign the certificate under penalties of perjury, misstating exempt status or intended use can push a violation into fraud territory. On the buyer’s side, keep the invoices, purchase orders, and internal requisition records that show how each item was used within your exempt function. If the Department ever asks, those records are how you demonstrate the exemption was properly claimed.
