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 contribution rate effective for the coming calendar year. This percentage is applied to taxable wages paid to determine the amount of employer contributions due.

This contribution rate notice serves to notify employers of their contribution rate and provides 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 For employers unable to access UCMS, a written appeal will be accepted if received within 90 days of the mailing date of the contribution rate notice. Written appeals should be sent to the Department of Labor & Industry, Office of UC Tax Services, Employer Account Services, PO Box 68568, Harrisburg, PA 17106-8568. The appeal must be received electronically or postmarked within 90 days from the date of the contribution rate notice and must specify the reason(s) why the contribution rate assigned is incorrect. If the ninetieth day from the date of the contribution rate 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.

(A voluntary contribution may be submitted at any time, but to affect a contribution rate, it must be received within 30 days from the mailing date of the Contribution Rate Notice or no later than 120 days after the beginning of such year, whichever is earlier.)

  • March 31, 2023 is the last day to file a timely rate appeal to the contribution rate reflected on the Contribution Rate Notice.
