A Contribution Rate Notice (Form UC-657) is mailed to employers at the end of each calendar year and shows the rate effective for the coming calendar year. This percentage is to be applied to taxable wages
paid that determines the amount of employer contributions due.
An employer who wishes to appeal a contribution rate may do so by accessing the UCMS employer self-service portal at www.paucemployers.state.pa.us
or by filing a written appeal within 90 days of the mailing date of the rate notice. Written appeals should be sent to the Department of Labor & Industry, Office of UC Tax Services, Employer Account Services, 651 Boas Street, Harrisburg, PA 17121. The appeal must be received electronically or postmarked within 90 days from the date of the notice and must specify the reason or reasons why the rate assigned is incorrect. If the ninetieth day from the date of the notice falls on a Saturday, Sunday or legal holiday, an appeal received electronically or postmarked on the next business day will be accepted as timely.
