Colorado Payroll Taxes

Colorado manages Unemployment Insurance through the Department of Labor and Employment (DLE). Employers are required to create an account to pay Unemployment Insurance through DLE.

Five Colorado cities require employees and employers to pay an additional Occupational Privilege Tax (OPT) per employee working in the following cities:

1. Aurora
2. Denver
3. Glendale
4. Greenwood Village
5. Sheridan

Each city sets its own flat rate based on a city-determined income threshold. The tax is paid by the employee and the employer monthly. The tax is based on where the employee performs the work, not where the employee lives. OPTs are paid through the city’s tax department.

Once CorpNet registers your business with the EDD, you will be issued an eight-digit Employer Payroll Tax Account Number that look like 000-0000-0. This is also referred to as a State Employer Identification Number, SEIN, or state ID number.
