Who Must File an Insurance Premium Tax Return – Captive Companies

Captive insurance companies shall pay to the Commissioner of Revenue Services, a tax on the direct premiums collected or contracted for on policies or contracts of insurance written by the captive insurance company during the year ending December thirty-first next preceding, after deducting from the direct premiums subject to the tax the amounts paid to policyholders as return premiums which shall include dividends on unabsorbed premiums or premium deposits returned or credited to policyholders, except that no tax shall be due or payable as to considerations received for annuity contracts.

Each captive insurance company shall pay to the Commissioner of Revenue Services, a tax on assumed reinsurance premiums collected or contracted for on policies or contracts of insurance written by the captive insurance company during the year ending December thirty-first next preceding, provided no tax under Conn. Gen. Stat. § 38a-91nn(b) shall apply to premiums for risks or portions of risks that are subject to taxation on a direct basis pursuant to Conn. Gen. Stat. §38a-91nn(a) of this section. No tax under Conn. Gen. Stat. § 38a-91nn(b) shall be payable in connection with the receipt of assets in exchange for the assumption by a captive insurance company of loss reserves and other liabilities of another insurer under common ownership and control, if such transaction is part of a plan to discontinue the operations of such other insurer and if the intent of the parties to such transaction is to renew or maintain such business with the captive insurance company.

Captive insurance companies filing a consolidated return must attach a list which contains the name and federal employer identification number of the companies included on the consolidated return.

Common ownership and control means ownership and control of two or more captive insurance companies by the same person or group of persons.

Ownership and control is defined as:

Stock corporations

Mutual or nonprofit corporations

The direct or indirect ownership of 80% or more of the surplus and voting power of the corporation.

Limited liability companies

The direct or indirect ownership of 80% or more of the membership interests in the company.

Sponsored captive insurance companies

A protected cell shall be treated as a separate captive insurance company owned and controlled by the protected cell’s participants.


Interest and Penalties

In general, interest and penalty apply to any portion of the tax not paid on or before the original due date of the return.

Late Payment Penalties

The late payment penalty is the greater of 10% of the tax due or $50. Late payments are subject to interest at the rate of 1% per month or fraction of a month until the tax is paid in full.
