Property tax in Pueblo, CO is calculated by taking your home’s actual value, applying Colorado’s 2026 residential assessment rate of 6.8% (with a 10% reduction built into the first $700,000 of value), and multiplying the result by the combined mill levy for your address. The Pueblo County Assessor sets the value, and the Pueblo County Treasurer collects the money. You can pay the full bill by April 30 or split it into two installments due February 28 and June 15.
How Your Bill Is Calculated
Three numbers decide what you owe: actual value, assessed value, and mill levy.
The Assessor first determines your property’s actual (market) value based on comparable sales and property characteristics.1Pueblo County Colorado. Assessor For 2026, residential property is assessed at 6.8% of actual value, with a 10% reduction applied to the first $700,000 of a home’s value before the rate kicks in.2Colorado Department of Local Affairs Division of Property Taxation. Residential Local Government Assessment Rate The minimum assessed value for any residential property is $1,000.
That assessed value is then multiplied by the mill levy. A mill equals $1 of tax for every $1,000 of assessed value.3Colorado Department of Local Affairs Division of Property Taxation. Property Tax Map Your total levy is the sum of rates set by every taxing district serving your parcel: the school district, fire district, library district, water and sanitation district, and the county itself. Two homes with identical values in different parts of Pueblo County can carry noticeably different bills because the overlapping districts are not the same.
A Worked Example
If your home is worth $400,000, subtract 10% ($40,000), leaving $360,000. Multiply by 6.8% and your assessed value is $24,480. For a home worth $900,000, the 10% reduction applies only to the first $700,000, so the 6.8% rate applies to $830,000, producing an assessed value of $56,440. Multiply either figure by your mill levy, divided by 1,000, to get the annual tax. The Treasurer’s site breaks out exactly which districts make up your total so you can see where the money goes.4Pueblo County Colorado. Treasurer’s Office
Payment Deadlines and Methods
Colorado law gives you two options. Pay the full amount by April 30, or pay in two equal halves with the first due by the last day of February and the second by June 15.5Justia. Colorado Code 39-10-104.5 – Payment Dates – Optional Payment Dates – Failure to Pay – Delinquency – Repeal These dates are state statute, so they are the same across Colorado.
The Pueblo County Treasurer accepts payments online (electronic check or credit card), by mail, or in person at the Treasurer’s office. Credit card payments carry a convenience fee of roughly 2.25%. Mailed payments count as timely if postmarked by the deadline; if you are close to the date, paying online or in person removes any postal risk.
What Happens If You Pay Late
There is no grace period. Interest accrues at 1% per month starting the day after the deadline. Miss February 28 on a half payment and interest runs from March 1 on that installment. Miss June 15 and it runs from June 16 on the second half. If you planned to pay the full amount by April 30 and missed, interest applies to the whole balance from May 1.5Justia.

Longer delinquency gets more serious. Pueblo County advertises unpaid parcels and sells a tax lien at auction, typically in October.6Pueblo County. Tax Lien Sale Notice 2025 A buyer pays off your delinquent taxes, interest, and fees and receives a lien certificate. To clear it, you owe the lien holder the full amount plus redemption interest, which in Colorado runs at the Federal Reserve discount rate plus 9% annually.
You have three years from the sale date to redeem the lien. If you don’t, the lien holder can apply for a Treasurer’s Deed, which transfers ownership of your property. A relatively small unpaid bill can cost you the house.
Exemptions That Lower Your Bill
Colorado has three exemptions that can reduce the taxable value of a Pueblo County home. None of them apply automatically. You have to file an application with the Pueblo County Assessor.
Senior Citizen Exemption
If you are at least 65 on January 1 of the application year and have lived in your home as your primary residence for at least 10 consecutive years, you can apply to exempt 50% of the first $200,000 of your home’s actual value from taxation.7Colorado Department of Local Affairs Division of Property Taxation. Property Tax Exemption for Senior Citizens in Colorado On a $300,000 home, that removes $100,000 of value from the calculation. One condition matters: the legislature must fund the exemption each year for it to take effect.
Disabled Veteran Exemption
Veterans with a permanent and total service-connected disability rating from the U.S. Department of Veterans Affairs can exempt 50% of the first $200,000 of actual value.8Colorado Department of Local Affairs Division of Property Taxation. Property Tax Exemption for Veterans with a Disability and Gold Star Spouses in Colorado The veteran must be the owner of record and must have owned and occupied the home as a primary residence since January 1 of the application year.9Colorado Division of Veterans Affairs. Property Tax Exemption There is no 10-year residency requirement.
Gold Star Spouse Exemption
Surviving spouses of service members who died in the line of duty or from a service-connected cause qualify for the same 50% exemption on the first $200,000 of actual value.8Colorado Department of Local Affairs Division of Property Taxation. Property Tax Exemption for Veterans with a Disability and Gold Star Spouses in Colorado You must own the home and have lived there as a primary residence since January 1 of the year you apply. Remarrying ends eligibility.
Protesting Your Valuation
Colorado reassesses real property every odd-numbered year, and the Assessor mails a Notice of Valuation in May showing the value that will apply for the next two tax years. If you think the number is too high, you have until June 8 to file a protest with the Assessor for real property, or until June 30 for personal property.10FindLaw. Colorado Code 39-5-122 – Notices and Hearings on Objections and Protests You can protest online, by mail, or in person.
Evidence wins protests. The strongest piece is comparable sales from the Assessor’s data collection period showing similar homes in your neighborhood selling for less than your valuation. Photos of deferred maintenance, structural issues, or unfavorable lot characteristics such as backing to a busy road or sitting in a flood-prone area also help. The Assessor issues a written determination, typically by early July.
If the Assessor denies your protest, you can escalate to the Colorado Board of Assessment Appeals by filing an electronic petition through its online portal.11Board of Assessment Appeals. The Appeal Process A hearing is scheduled, usually no earlier than four months after the petition is accepted, and the Board issues a written decision. You can also take an appeal to district court.
Because your value is locked in for two years, skipping a protest in a reappraisal year means living with the number until the next cycle. Filing costs nothing.
Looking Up Your Record
The Treasurer and Assessor each run an online lookup. The fastest search uses your 10-digit schedule number, printed in the upper corner of previous tax notices and valuation statements. You can also search by property address or owner name. The Assessor’s site shows the property’s assessed value, classification, and physical characteristics;1Pueblo County Colorado.
