Any self-employed person may opt-in to the state plan. This includes sole proprietors, independent contractors, partners, and joint ventures. When electing to use the state plan, self-employed persons must participate for an initial period of three years, and one year thereafter.
Self-employed people who choose to participate must cover the employee share of the premium and are required to work 820 hours in the qualifying period to be eligible for benefits.
