- Required Unemployment Reports
You must submit premium and wage reports every quarter. Most employers can file both premium and wage reports through MyUI Employer. You may also be required to provide responses to requests for information like the Request for Verification of Weekly Earnings or employee separation information. Providing responses timely helps keep improper payments to a minimum and helps you avoid costs.
- Register for MyUI Employer
Manage your unemployment insurance premium account information using MyUI Employer. Employers who pay unemployment insurance premiums and their designees, for example employees, accounting, or legal staff can utilize this tool to manage their accounts.
- Ensure Proper Worker Classification
Ensure you are classifying your workers correctly.Employee/worker misclassification occurs when an employer mistakenly classifies a worker as an independent contractor rather than an employee.
- Online Job Separations
When an employee is separated from employment and files a claim to collect unemployment benefits, any employer listed on the claim are notified via letter and are required to submit job-separation documentation. This documentation allows us to make decisions about allowing or denying unemployment benefits to be paid to the previous employee. Our new email notification and response tool allows employers to respond quickly, which gives us information sooner and helps us make more accurate decisions.
- Verify Workers' Compensation Coverage
All businesses with employees operating in Colorado are required to have workers’ compensation insurance, regardless of the number of employees, whether the employees only work part-time or if they are members of the same family.
- Verify Wage &, Hour Law Compliance
Verify your compliance with minimum wage, overtime, and pay laws and regulations.
