Determining your standard premiums.
Employers are required to pay accident fund, medical aid stay-at-work and supplemental pension fund premiums according to chapter 296-17 WAC. Standard premiums are the premiums an employer pays to the accident and medical aid funds under chapter 296-17 WAC for employment during the coverage period, and do not include either stay-at-work or supplemental pension fund premiums.
For an employer enrolled in a group after the start of a group's coverage period, we will only consider the employer's standard premiums for the calendar quarters for which the employer was enrolled.
