SURPLUS LINES

Surplus lines insurance is regulated under Title 33, Chapter 2, Part 3, MCA, and ARM Chapter 6.6—Insurance Department; Subchapter 6.6.28.

When Montana is the home state at the time of the surplus lines insurance transaction, surplus lines filings are made on approved forms provided by the CSI.

Montana imposes a 2.75% premium tax, calculated on the total premium, and a 2.5% fire tax pertaining to the portion of the policy where a fire coverage premium is being charged—that must be collected by the surplus lines insurance producer.
