TDI is required by the Act to administer and enforce the Act. Owners/operators operating amusement rides must pay a fee of $40 per year for each amusement ride subject to the Act. The fees must be paid by check or money order made payable to TDI; or, if paying online, the fee must be submitted through the following website: https://feepay.txapps.texas.gov/tdi/amusement-ride-sticker-payments, which may add a surcharge for the transaction. Except for overpayments resulting from mistakes of law or fact, all fees are nonrefundable and nontransferable.
