The FTA collects the fee.
Each year, when assessing the liability to pay VAT, the FTA shall allocate each undertaking liable to pay the fee to a tariff category and invoice it for the fee.
If an undertaking has made no VAT returns or its returns are clearly inadequate, the FTA shall use its discretion to allocate the undertaking to a tariff category.
If allocation to a tariff category for the tax period ending in the previous calendar year is temporarily impossible, the FTA shall invoice the fee when the tariff category has been determined.
