Until July 1, 2007, licensed insurers were charged 2% of premiums for insurance and risks written within the state. In connection with a study and recommendation intended to encourage redomicile of insurers into the state, a schedule of rate reductions was instituted for most commercial insurance lines. The rate became 1.75% July 1, 2007, 1.5% on January 1, 2009 and 1.25% on January 1, 2010. The Committee of Conference Special Session of 2010 froze the rate at 1.25% indefinitely. The tax also applies to certain nonprofit health insurers and dental insurers. Annually, on March 15, authorized insurers are required to file a final report showing direct premiums and other insurance related items. In accordance with Chapter 277:3, Laws of 2006, the entire premium tax for the previous calendar year is due on or before March 15th.
