THA is an independent municipal corporation formed under Washington State law. A five member Board of Commissioners appointed by the Mayor of the City of Tacoma governs THA. THA has no taxing authority and receives no regular operating funds from the City of Tacoma or the State of Washington. Most of its funds comes from rents that it charges to its tenants, fees that it earns in administering its various programs, subsidies from the federal government for its federal programs, developer fees that it earns when it builds or rebuilds, and grants from public and private sources.

THA or related tax-credit partnership owns about 1,650 dwelling units of various designs and types scattered throughout the City of Tacoma.
