MACo History


The "Montana Association of County Commissioners" was formed in January 1909, for the purposes of providing advocacy on behalf of its members at the State Legislature. In 1973, the Association was reorganized as the "Montana Association of Counties" to allow for the creation of a permanent office and authorized the hiring of an Executive Director and appropriate staff.

In 1985, a group of Montana counties banded together to create the "MACo Joint Powers Authority (JPA) Workers' Compensation Trust," in response to rapidly increasing costs for workers' compensation coverage for county employees. In 2015, the Trust was renamed to the "Workers Compensation Trust (WCT)."

In 1986, the "MACo Joint Powers Insurance Authority (JPIA)" was created to provide liability and general insurance coverage for member counties, in response to the change in the market which made policies for certain liability coverages unavailable and/or unaffordable for members. In 2015, the Trust was renamed to the "Property & Casualty Trust (PCT)."

In 1999, the MACo Administration building was built, with ownership equally shared between MACo, the JPA (now the WCT) and the JPIA (now the PCT).

In 2005, the "MACo Health Care Trust (HCT)" was created to provide group health benefits to member counties and special districts.

In 2006, a second building was built by the PCT/WCT.

MACo as an Association provides third-party administration services to the HCT, PCT, and WCT through annual service agreements.

Following extensive due diligence by the Boards of the Trusts, it was determined that bringing services in-house and hiring staff would save members considerably, by eliminating the continually increasing costs of third-party administrators and contracts:

  1. In July 1992, PCT marketing was brought in-house.
  2. In October 1987, WCT Risk Management was brought in-house
  3. In January 2006, PCT/WCT claims administration was brought in-house.
  4. In April 2007, HCT Administration, marketing, and member services were brought in-house.
  5. In October 2008, Legal Counsel and Defense Services were brought in-house.
