31 C.F.R. § 50.94 – Collecting the surcharge.

(a) Insurers shall collect a Federal terrorism policy surcharge from policyholders as required by Treasury.
(b) Policies subject to the Federal terrorism policy surcharge are those for which direct written premium is reported on commercial lines of business on the NAIC's Exhibit of Premiums and Losses of the NAIC Annual Statement (commonly known as Statutory Page 14) as provided in § 50.4(w)(1), or equivalently reported.
(c) For policies subject to the Federal terrorism policy surcharge, the surcharge shall be imposed and collected on a written premium basis for policies that become effective or renew during the assessment period. All new, renewal, mid-term, and audit premiums for a policy term are subject to the surcharge in effect on the policy term effective date. Notwithstanding this paragraph, if the premium for a policy term that would otherwise be subject to the surcharge is revised after the end of the reporting period described in § 50.95(e), then any additional premium attributable to such revision is not subject to the Surcharge. For purposes of this subpart:
1. (1) Written premium basis means the premium amount charged a policyholder by an insurer for property and casualty insurance, including all premiums, policy expense constants and fees defined as premium pursuant to the Statements of Statutory Accounting Principles established by the NAIC, as adopted by the state for which the premium will be reported.
2. (2) In the case of a policy providing multiple insurance coverages, if an insurer cannot identify the premium amount charged a policyholder specifically for property and casualty insurance under the policy, then:
  1. (i) If the insurer estimates that the portion of the premium amount charged for coverage other than property and casualty insurance is de minimis to the total premium for the policy, the insurer may impose and collect from the policyholder a surcharge amount based on the total premium for the policy, but
  2. (ii) If the insurer estimates that the portion of the premium amount charged for coverage other than property and casualty insurance is not de minimis, the insurer shall impose and collect from the policyholder a Surcharge amount based on a reasonable estimate of the premium amount for the property and casualty insurance coverage under the policy.
3. (3) The Federal terrorism policy surcharge is not considered premium.
(d) A policyholder must pay the applicable Federal terrorism policy surcharge when due. The insurer shall have such rights and remedies to enforce the collection of the surcharge that are the equivalent to those that exist under applicable state or other law for nonpayment of premium.
(e) When an insurer returns an unearned premium, or otherwise refunds premium to a policyholder, it shall also return any Federal terrorism policy surcharge collected that is attributable to the refunded unearned premium. Notwithstanding this paragraph, if the written premium for a policy is revised and refunded after the end of the reporting period described in § 50.95(e), then the insurer is not required to refund any Surcharge that is attributable to the refunded premium.
(f) Notwithstanding paragraphs (a), (b), and (c) of this section, if the expense of collecting the Federal terrorism policy surcharge from all policyholders of an insurer during an assessment period exceeds the amount of the Surcharges anticipated to be collected, such insurer may satisfy its obligation to collect by omitting actual collection and instead remitting to Treasury the amount otherwise due.
(g) The Federal terrorism policy surcharge is repayment of Federal financial assistance in an amount required by law. No fee or commission shall be charged on the Federal terrorism policy surcharge.
