If you rent a house or condominium to someone for less than 30 days in Colorado it is likely sales tax is owed on that rental. There may also be other taxes owed as well including line items for a county lodging tax etc.
If you use a management company to rent the property be sure that they know and are in compliance with the state and local sales tax statutes regarding lodging for the county in which the property is situated. Ultimately the responsible party for complying with sales tax regulations is the landlord and not necessarily the management company. In other words, ignorance is not a defense.
