Unemployment Insurance

Colorado's unemployment insurance rates vary among established employers, depending upon the history of taxes and benefits paid, and the Unemployment Insurance Fund balance.

The tax rate is a combination of three separate factors including the base rate, an annually computed surtax, and a solvency tax surcharge.

For the majority of new employers for calendar year 2008, the beginning base tax rate is 0.017, the surtax is 0.0022, and the solvency surcharge is 0.006, resulting in a combined rate of 0.0252 on the first $10,000 of each employee's annual earnings.

Employers in construction-related businesses may be subject to a different tax base rate.
