Licensing and Sales/Use Tax



Licensing and Sales/Use Tax

Effective January 1, 2020, the City of Castle Pines will self-collect the City Sales Tax and businesses will no longer file the City’s Sales Tax with the Colorado Department of Revenue. Therefore, sales made beginning with January 2020 will be due and payable directly to the City. Stay tuned for additional changes and information on the City’s website including online business license application and online tax return filing.
