Property Tax Information

The County Treasurer mails tax notices January of each year. Failure to receive such tax statement(s) shall not preclude collection by the Treasurer of the amount of taxes due and payable (C.R.S. 39-10-103, as amended). Tax notices are sent to the property owner. If a loan company is responsible for payment, the property owner is responsible to forward it to them.
