Tex. Parks and Wildlife Code § 47.031

(a) All licenses and permits issued under the authority of Chapter 47 of this code are valid only during the yearly period for which they are issued without regard to the date on which the licenses are acquired. Each yearly period begins on September 1 or another date set by the commission and extends through August 31 of the next year or another date set by the commission. The commission by rule may set the amount of a license fee for a license issued during a transition period at an amount lower than prescribed in this chapter and provide for a license term for a transition period that is shorter or longer than a year.

(b) All licenses and permits issued under the authority of Chapter 47 may not be transferred to another person except that a license issued in the name of a business shall remain valid for the business location specified on the license or permit if a change of ownership and/or business name occurs. A license issued under the authority of Section 47.009, 47.011, 47.014, or 47.016 may be transferred to a new address if the business moves to another location. A license issued under the authority of Section 47.007, 47.010, or 47.013 may be transferred to another vehicle or vessel or to a new owner of the same vehicle or vessel. The commission, by regulation, may prescribe requirements necessary to clarify license and permit transfer procedures and may prescribe, by regulation, forms to be used and fees to be charged for transfer of licenses and permits in this chapter and for duplicate license plates and duplicate or replacement licenses and permits.
