Those electing coverage under this section must elect coverage for both family leave and medical leave and are responsible for payment of one hundred percent of all premiums assessed to an employee under RCW 50A.10.030. The self-employed person must file a notice of election in writing with the department, in a manner as required by the department in rule. The self-employed person is eligible for family and medical leave benefits after working eight hundred twenty hours in the state during the qualifying period following the date of filing the notice.

(2) A self-employed person who has elected coverage may withdraw from coverage within thirty days after the end of each period of coverage, or at such other times as the commissioner may adopt by rule, by filing a notice of withdrawal in writing with the commissioner, such withdrawal to take effect not sooner than thirty days after filing the notice with the commissioner.

(3) The department may cancel elective coverage if the self-employed person fails to make required payments or file reports. The department may collect due and unpaid premiums and may levy an additional premium for the remainder of the period of coverage. The cancellation shall be effective no later than thirty days from the date of the notice in writing advising the self-employed person of the cancellation.

(4) Those electing coverage are considered employers or employees where the context so dictates.
