Online Tax Information and Payments

Per Colorado Revised Statutes, tax notices are mailed once a year, usually in January. It is the responsibility of the taxpayer to pay property taxes, whether a bill is received or not. Payments may be made in half payments or in one full payment as follows:

  • First half payment due February 28
  • Second half payment due June 15
  • Full payment due April 30

Interest is charged at 1% per month after each due date. Delinquent notices are mailed July 1. All payments received after September 1 must be paid in the form of cash or cashier’s check. Delinquent taxes are subject to be advertised and sold at the annual tax lien sale, usually held in November.


Tax payments can be made online at Grand County Treasurer's site.  


We accept Master Card, Visa, American Express and E-Checks. A portal fee of 2.5% for all credit cards and a $2.50 fee for all E-Checks will be applied. There is a ceiling limit of $25,000 for the total amount in your cart.
