Tennessee has had captive insurance legislation in place since 1978. In 2011, the state undertook a major rewrite of its captive laws to expand the types of captives permitted as well as the lines of coverage captives can provide. Additional revisions were passed in 2016, 2017, and 2019. Among other improvements, the changes allow a protected cell captive to be spun off as a stand-alone captive or to transfer from one Tennessee cell facility to another and allow captives to use any type of limited liability company (LLC) structure including series LLCs (a popular form with protected cell companies). Other recent changes add tax benefits for redomestications and allow individual protected cells to merge with each other or to apply for dormancy. State regulators intend to retain existing captive business and to capture the interest of organizations in Tennessee and other nearby states that have formed captives in other domiciles.
