Premium Rates

Each year, we determine premium rates for employers based on a number of factors, including the amount of money already paid and unemployment benefit payments made to former employees. Employers must pay annual premiums for each employee's chargeable wages. The chargeable wage limits are:

$13,600 for 2020

$13,100 for 2019

$12,600 for 2018

$12,500 for 2017

$12,200 for 2016


Standard Rate (New Employers)

New employers begin at a standard rate depending on the type of business activity. For rate year 2020 the rate consists of only the base rate. There are no surcharges in effect for 2020. However, between 2004-2012, the standard rate consisted of three components: a base rate, a solvency surcharge and a surtax. For the years 2013 through 2017, the standard rate consisted of two components: a base rate and a bond principal rate. More>

Computed Rate

After an employer has paid wages for a sufficient number of quarters, the employer is eligible for a computed rate based on the experience of the business. More>

Rate Increases

There may be several reasons why your business sees a rate increase. Some of the common reasons include:

  • the average annual payroll increased
  • there were new benefit charges to the account
  • the level of the Unemployment Insurance Trust Fund decreased
  • the business stopped paying wages for a period of time and lost its computed rate

Claims for Benefits

Premiums are contributions paid by Colorado employers to help protect the economy. We administer these contributions by paying unemployment insurance benefits to persons unemployed through no fault of their own. More>

Bond Principal Repayment

In order to increase the financial health of the Unemployment Insurance Trust Fund and provide relief to Colorado employers, a bond transaction totaling $630 million was secured. The bond was repaid in 2017. The bond repayment assessment will no longer be included in your premium payments effective with rate year 2018. More>
