Treasurer frequently asked questions

When are my property taxes due?
We collect property taxes one year in arrears (two years on oil & gas property tax). For example, 2023 property tax is collected in 2024. Taxes may be paid with no penalties or interest each year in either one full payment due by April 30, or two half payments due February 28 and June 15.

Does my mortgage company receive a tax notice?
No. In January of each year, a tax notice is sent to the property owner of record. If your mortgage company escrows your property tax each year, please check with them to be sure payment is made.

What if I don’t receive my tax notice?
Property tax notices sent out each year are not a bill – they are a notice. Property tax is owed each year whether a notice is received. If you have not received a tax notice by mid-February each year, please call us at 719-486-4117 and a duplicate notice will be sent.

Full payments – after the close of business of business on April 30

If property tax becomes delinquent, a delinquent notice will be sent to the owner of record (this typically happens during the first week of July each year), which states the amount due as well as any further action that may be taken to collect the delinquent property tax.

When is the annual tax lien sale held?
The annual tax lien sale is held in end of October early November each year. A listing of property tax accounts going to tax lien sale will be advertised in the local Leadville Herald Democrat, and will be posted online in late September and throughout October each year.

Why does my tax amount change?
The amount of property tax you pay is based on your property value (the value placed on your property by the County Assessor) and the mill levy for the taxing district where the property is located. Mill levies are subject to change each year and property values are subject to change every two years.

What is a mill levy?
A mill levy is a rate determined by taxing authorities providing services within your taxing district (the district in which your property is located) that is applied to your assessed property value. This is then used to calculate the amount of property tax you will pay. Each individual taxing entity, such as a school, county, city, housing/subdivision district, water and sanitation district sets its own mill levy and are listed on your tax notice.

How are property taxes calculated?

(Actual value) x (assessment rate) x (mill levy) / 1,000 = tax dollars

Did I receive the Senior or Veterans tax exemption? Where do I find it on my tax notice?
If you received one of these exemptions, it will be located in the top portion of your tax notice under the list of mill levies. Colorado law does not allow you to receive both exemptions. For more information on Senior or Veterans exemptions, please visit the Assessor’s Office page

Can I receive both the Senior and Veterans tax exemptions?
No – the law in Colorado does not allow you to receive both exemptions.

Why do I receive a Tax Notice when it is my mortgage company that pays the property taxes on my home?
The law in Colorado requires that Tax Notices be sent to all Owners of Record whether or not another party remits the taxes due.

What happens if my taxes aren’t paid?
If after the June 15th second-half payment deadline, taxes are still due on a property, a Delinquent Tax Notice is
sent to the Owner of Record (usually during the first week in July) which states the amount of taxes and interest due, as well as any further actions the Treasurer’s Office may be required by law to take to collect those taxes.
