Assessor

Assessor's Office

The Assessor's Office is responsible for identifying, classifying, and valuing all real and personal property in Gilpin County according to statutory provisions. The equitable assessment of property ensures a fair tax distribution relative to the value of similar properties.

eNotices

The Gilpin County Assessor's Office participates in the eNotice online program. Simply go to https://enoticesonline.com/ to log into the eNotice website. This program allows a property owner to receive their valuation notices via email instead of by regular mail. As an added benefit, the website will have a repository of all the notices sent this way for future access by the property owner. Each owner that signs up will have a separate and distinct account. This is a convenient way to receive notices and have easy access to those notices at any time, day or night.

FAQs and Other Helpful Information

How is my property value determined?

Values are determined by comparing your property with properties that are similar in location, design, size, age and amenities and which sold during the re-assessment period. This is known as the Sales Comparison or Market Approach.

How are property taxes calculated?

Property taxes are calculated using the actual property value, the assessment rate, and the mill levy using the formula: Actual Value x Assessment Rate = Assessed Value x Mill Levy = Taxes Due

Who sets the mill levy?

The mill levy is set by the individual taxing authority such as school, county, city, fire and sanitation districts. These authorities provide services to you and are listed on your last tax notice.

Why are the taxes on my vacant land so high compared to my land with the house?

Vacant land is taxed at a rate of 27.9% versus that of residential property which is taxed at 6.765%

Is there any way to lower the taxes on my vacant land?

If the vacant land adjoins your residence you may be able to do what is called a Boundary Line Elimination (B.L.E.), which would combine both lots into one. If you do this you will have only the one lot, which will then be assessed as improved land (no longer vacant). Please be aware that if you do decide to do a B.L.E. it can never be reversed.

Who would I talk to about a B.L.E.?

Please reach out to Community Development at 303-582-5831. 

Doesn't the Tabor Amendment for 1992 prevent my taxes from rising?

No. The Tabor Amendment (Amendment 1 of 1992) controls the amount that the State and local governments can collect and spend. It does not limit the rate of increase of an individual tax bill.

If I do not agree with the actual value, what steps should I take?

A property owner may protest the value of their property during the month of May. Each year property owners are mailed a Notice of Value with a protest form. The protest form is also available on the county web site. The protest form must be returned to our office postmarked no later than June 8. If you appoint an agent to act on your behalf, that person needs your written authorization on a Statement of Authority.

What happens after I appeal?

The Assessor's office will review each appeal and make a decision by June 30. A Notice of Determination will be mailed at that time. Property owners should be prepared for the Assessor's office to make a physical inspection of the property. If you are dissatisfied with the Assessor's response, you may appeal to the County Board of Equalization.
