Oklahoma does not automatically offer sales tax exemption to all entities that are recognized by the Internal Revenue Service. Sales tax exemptions are governed according to Oklahoma Statue Title 68, Section 136. Seventy classifications of nonprofit and charitable organizations are eligible to apply for a permit. Your organization must have a Federal Employer Identification Number before submitting an application. Apply for an identification number at the IRS website.
Access the Oklahoma Tax Commission website and download an Oklahoma Sales Tax Exemption Packet (see Resources), or contact the Oklahoma Tax Payer Assistance Office at 800-522-8165 to request one by mail.
Examine the Requirements and Documents to Qualify section of the packet. It lists the specific organization types approved for tax-exempt status. The category titles provide the document number of the specific application required, as well as a list of supporting documentation that is needed for your type of organization. Other useful information such as exceptions, limitations, rules and contact information is listed below each heading.
Fill out the application, form 13-16-A, which is found on page 5 of the packet. Some types of organizations require an alternate application form. A complete list of these is included on page 4 of the packet.
Mail the application and supporting documentation to Oklahoma Tax Commission, Taxpayer Assistance Division, P. O. Box 26920, Oklahoma City, OK 73126. The commission often requires documentation from other sources to qualify an entity for exemption, such as a letter from the IRS that proves federal exemption, articles of incorporation, by-laws or financial statements. Specific details for each classification are listed in the Oklahoma Sales Tax Exemption Packet.
