637 Registration Program
Under the Code and regulations, each person who engages in certain specified activities relating to excise tax must be registered by the Internal Revenue Service (IRS) before engaging in that activity. In other cases, a person is required to be registered by the IRS in order to receive an excise tax benefit, such as, the right to sell or buy an article tax-free or to file a claim. Form 637, Application for Registration (For Certain Excise Tax Activities), is used to apply for registration for activities under sections 4101, 4222 and 4682. Form 637 contains a listing of activities for which registration is required or allowed. A person can register for more than one activity on Form 637, if applicable. In order to receive and retain a registration, a person has to meet certain standards referred to as “registration tests.” The registration tests vary according to the activity; it may include an inspection of the person’s business premises during normal business hours without advance notice. If your application is approved, the IRS will issue a Letter of Registration. The letter will include the activities you are registered for, the effective date of the registration, and your registration number. Each business unit that has, or is required to have, a separate employer identification number is treated as a separate person, and must submit their own Form 637 application.
