Swinomish Trust Improvement Use and Occupancy Tax

image The Swinomish Indian Tribal Community has adopted a Swinomish Trust Improvement Use and Occupancy Tax Code (STC 17-11) that applies to individuals who own a home, commercial structure, or other improvement on leased trust land within the Swinomish Indian Reservation. The Code establishes a Tribal tax on the use and occupancy of permanent improvements on leased Swinomish Reservation Trust land. The Tribe previously adopted an Interim Trust Improvement Use and Occupancy Tax Code (STC 17-10) which applied only to taxes payable for the years 2011-2014.
Using this website, you can stay informed about taxes on the Swinomish Reservation and look up information relating to valuations and taxes for specific parcels.
