Colorado has a structured approach to taxing the wages of both resident and nonresident remote employees under its taxation laws.
Overview of Colorado's Tax Posture
- Complexity Bucket: Colorado's tax complexity rating is classified as Baseline.
Employer Withholding Obligations
- Employers in Colorado must withhold state income tax from wages paid to both resident and nonresident employees. This withholding is based on percentages defined by the Colorado Department of Revenue. Employers are responsible for ensuring that deductions are accurately calculated and submitted to the state.
Sourcing of Nonresident Wages
- For nonresident individuals, wages are sourced based on income derived from activities performed within Colorado. This includes:
- Earnings related to property or business interests within the state.
- Compensation attributed to services performed in Colorado.
- Nonresident income is subject to apportionment based on Colorado nonresident federal adjusted gross income in relation to total federal adjusted gross income, as per Section 39-22-104 of the Colorado Revised Statutes.
Reciprocity Agreements
- Colorado does not have reciprocity agreements with other states. Therefore, nonresidents are taxed on income earned from sources in Colorado without regard to their state of residence.
De-minimis Thresholds
- Colorado does not currently maintain a de-minimis threshold for remote work or for income earned by nonresident employees.
Local/City Wage Taxes
- Local or city wage taxes do exist in Colorado. Notably, cities like Denver impose additional occupational taxes. Employers must comply with local tax requirements, which may necessitate additional withholding from employee wages.
In summary, Colorado has a clear framework for the taxation of wages involving both resident and nonresident employees, with specific emphasis on employer obligations for withholding, detailed sourcing rules for nonresidents, and the absence of reciprocity agreements, while also managing local tax responsibilities.
