26 CFR 51.8 - Notification and payment of fee.
(a) Notification of final fee calculation. No later than August 31st of each fee year, the IRS will send each covered entity its final fee calculation for that year. In any fee year, the IRS will base its final fee calculation on data provided to it by the Agencies as adjusted pursuant to the dispute resolution process. The notification to a covered entity of its final fee calculation will include -
(1) The covered entity's allocated fee;
(2) The covered entity's adjustment amount calculated as described in § 51.5;
(6) The final determination with respect to error reports.
(b) Differences in preliminary fee calculation and final fee calculation. A covered entity's final fee calculation may differ from the covered entity's preliminary fee calculation because of changes made pursuant to the dispute resolution process described in § 51.7. Even if a covered entity did not file an error report described in § 51.7, a covered entity's final fee may differ from a covered entity's preliminary fee because of a change in data reported by the Agencies after resolution of error reports, including a change in the aggregate prescription drug sales figure. A change in aggregate prescription drug sales data can affect each covered entity's fee because each covered entity's fee is a fraction of the aggregate fee collected from all covered entities. A covered entity's final fee may also differ from its preliminary fee calculation because the data used in the preliminary fee calculation may have contained inaccurate branded prescription drug sales information that was corrected or updated at the conclusion of the dispute resolution process.
(c) Payment of final fee. Each covered entity must pay its final fee by September 30th of the fee year. For a controlled group, the payment must be made using the designated entity's EIN as reported on Form 8947. The fee must be paid by electronic funds transfer as required by § 51.6302-1. There is no tax return to be filed for the fee.
(d) Joint and several liability. In the case of a controlled group that is liable for the fee, all members of the controlled group are jointly and severally liable for the fee. Accordingly, if a controlled group's fee is not paid, the IRS will separately assess each member of the group for the full amount of the controlled group's fee.
