A major source of funding for services from the City’s General Fund, including police services, fire services and library services, is property tax. The City levies a property tax of 13.42 mills. A mill is equal to $1 dollar of property tax for every $1,000 of assessed value of a property. Property assessment is a function of the county assessor. For more information on property assessment and billing or payment of property taxes visit the Boulder County Assessor's Office at

Under state statute, the City cannot raise its mill levy rate without a vote of the electors in a November election. The 13.42 rate of mill levy has been in place since 1991. The City is projected to receive up to $16,210,313 of property tax revenue for its General Fund in 2017 after deduction of a 1.5% collection fee from the county treasurer.
