How are my property taxes calculated?

Property taxes are based on two things, the assessed value of the property set by the Assessor and the mill levies set by the various taxing authorities (the county, school districts, fire districts, sanitation districts, etc.) in whose boundaries the property falls. Property taxes are calculated by multiplying the assessed value by the sum of the individual mill levies (see Assessor's webpage).

Who sets the value for my property?

Actual and assessed values are determined by the County Assessor.

What is a Mill Levy?

The mill levy is the tax rate used to calculate the tax bills of properties within a taxing area. One mill is one dollar per $1,000 of assessed value.

What do my property taxes pay for?

Property taxes help to pay for local services such as: public schools; law enforcement and fire protection; road maintenance; public libraries; parks and recreational facilities; public health and human services.

I can’t afford to pay my property taxes on time. What should I do?

We strongly advise you to contact our office as early as possible if it looks like you will not be able to pay your taxes on time (303-582-5222).

What happens if I don’t pay the property taxes?

Property taxes that are paid after deadlines will accrue interest at the rate of 1% per month. Taxes that remain unpaid in September will be advertised in October for the Tax Lien Sale in November and this will incur additional charges as well as result in a lien being placed on the property if the taxes are not paid prior to the day of the sale. Having to redeem a tax lien on a property is definitely more costly than paying the taxes prior to a lien being placed on the property. Moreover, a tax lien could eventually result in the loss of the property.

Are there programs that can assist me in paying my property taxes?

There may be assistance programs. The State of Colorado currently has programs to assist senior citizens and veterans in paying their property taxes. Contact the Assessor’s office for information on these programs (303-582-5451).
