Tax Rates/Contribution Rate Notice

Notifying Employers of Their UC Tax Rates

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.

This rate notice serves to notify employers of their contribution rate and explains each of the factors comprising the total rate. Choose one of the following links to view:

Appealing a UC Tax Rate

An employer who wishes to appeal a contribution rate may do so by accessing the UCMS employer self-service portal at 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.

If the Office of UC Tax Services issues a denial of a contribution rate appeal, the employer has the right to file a second-level appeal with the UC Tax Review Office.
