The New York State Department of Taxation and Finance issued an advisory opinion determining that non-US unauthorized life insurance companies’ premiums were not includable in the New York State insurance franchise tax apportionment factor. The Department reasoned that the apportionment statute requires a life insurance company to report its premiums on a basis “consistent with” the Insurance Law filing requirements for authorized insurers. The applicable Insurance Law statute: (1) does not apply to unauthorized insurers; and (2) requires (authorized) non-US insurers to report only their US business and assets. Therefore, the Department concluded that a non-US unauthorized life insurance company’s premiums were neither “New York premiums” nor “total premiums” (the premium factor numerator and denominator, respectively). Notably, the Department relied on Insurance Law filing requirements to determine the insurance companies’ tax treatment. N.Y. Advisory Opinion TSB-A-17(2)C (Oct. 4, 2017).
