The Colorado personal property tax applies to tangible business assets like machinery, furniture, computers, and equipment. For the 2026 tax year, most business personal property is assessed at 26% of its actual value, and any business whose total personal property in a single county is worth $56,000 or less is completely exempt. The tax is administered county by county, and the declaration schedule is due to the county assessor by April 15.
What Colorado Taxes and Who Owes It
Colorado defines personal property as everything that can be owned and is not real property (land and permanently attached structures). In practice, the tax targets tangible business assets: office furniture, computers, machinery, manufacturing equipment, tools, and fixtures used in a commercial operation.1Assessors’ Library. Chapter 1 – Applicable Property Tax Laws All personal property in Colorado is taxable unless a specific exemption applies.2Colorado Department of Local Affairs Division of Property Taxation. Personal Property Frequently Asked Questions
The tax is owed to the county where the property physically sits. If your business has equipment in more than one county, you file a separate declaration schedule in each. Whoever owns, controls, or possesses the property on January 1 is responsible for reporting it.3Colorado Department of Local Affairs Division of Property Taxation. Personal Property Forms
Leased equipment splits along the lease type. Under a true lease where the lessor keeps ownership, the lessor reports and pays. Under a financing or conditional lease where title passes to the lessee, the lessee picks up the reporting obligation.4Jefferson County. Business Personal Property Information
What Is Exempt
Several broad categories fall outside the tax. The one that eliminates the tax entirely for most small operations is the de minimis exemption: if the total actual value of your taxable personal property within a single county is $56,000 or less, you owe no tax for the 2026 tax year.5Colorado Department of Local Affairs Division of Property Taxation. Personal Property Declaration Schedules That threshold is adjusted every two years for inflation under C.R.S. 39-3-119.5, so confirm the current figure before relying on it in a later year.6FindLaw. Colorado Code 39-3-119.5 – Personal Property Exemption The calculation combines all your taxable items across every business location in that county. If you qualify, keep records but you generally will not need to file a declaration schedule.
Business inventory held primarily for sale is also exempt, covering raw materials, work in progress, finished goods, and replacement parts held by manufacturers, wholesalers, or retailers.7Colorado Department of Local Affairs Division of Property Taxation. Common Exemptions The distinction that matters: equipment you use in the business is taxable; identical equipment sitting in your warehouse waiting to be sold to a customer is not. Livestock, agricultural products, and agricultural equipment are exempt as well.8Colorado General Assembly. Business Personal Property Tax
Most motor vehicles pay a specific ownership tax at registration rather than personal property tax, and the same treatment applies to self-propelled construction equipment classified as special mobile machinery. Personal aircraft pay a fuel excise tax in lieu of personal property tax.2Colorado Department of Local Affairs Division of Property Taxation.

How the Tax Is Calculated
Two steps produce your tax bill: the assessor sets an actual value, then applies a statutory assessment rate, and then the local mill levy is multiplied in.
Actual Value
The assessor works from cost factor tables published by the Division of Property Taxation. After selecting the industry category for the type of property, the assessor applies a cost factor tied to the property’s year of acquisition. Your original cost is multiplied by that factor to estimate reproduction cost new, and a depreciation table then reduces it for age and wear.9Colorado Department of Local Affairs Division of Property Taxation. Personal Property Tables The result is not resale value and not what you paid. It is a standardized figure meant to treat similar assets uniformly statewide.
Assessment Rate and Mill Levy
For the 2026 tax year, most personal property is assessed at 26% of actual value. Property listed under improved commercial subclass codes and agricultural property is assessed at 25%.10FindLaw. Colorado Code 39-1-104 – Valuation for Assessment These rates have shifted more than once through recent legislation, so don’t assume last year’s figure carries over. The assessed value is then multiplied by the combined local mill levy set by your county, school district, and other taxing entities.
A rough example: if your equipment has an actual value of $100,000 at the 26% rate, your assessed value is $26,000. At a combined mill levy of 80 mills (0.080), the tax bill is $2,080.
Filing the Declaration Schedule
Businesses with more than $56,000 in total actual value of personal property per county must file a personal property declaration schedule with the county assessor by April 15 each year.11Colorado Department of Local Affairs Division of Property Taxation. Filing Requirements The schedule discloses everything you own, control, or possess as of January 1.
For each item, you report a description, the year of acquisition, and the original cost. Original cost in Colorado is broader than the purchase price alone. It includes acquisition cost, sales and use tax, installation charges, and freight to the point of use.3Colorado Department of Local Affairs Division of Property Taxation. Personal Property Forms Pull those figures from your accounting ledgers or fixed-asset depreciation schedules rather than estimating. For assets bought in a bulk purchase, allocate cost to the individual items. The assessor may request any additional information needed to value the property.
Forms are available on your county assessor’s website or through the Division of Property Taxation, and many counties offer downloadable PDFs or online filing portals. Filling in the schedule from your own records keeps the assessor from having to estimate values on your behalf, which rarely works in your favor.
If you cannot meet April 15, you can request a written extension of 10 or 20 days, submitted to the assessor by April 15. Extensions cost $2 per day ($20 for ten days, $40 for twenty), regardless of how many schedules you need to file.11Colorado Department of Local Affairs Division of Property Taxation. Filing Requirements
Penalties for Filing Late or Not Filing
Missing the deadline without an extension triggers a late filing penalty of 15% of the taxes due or $50, whichever is less. The same penalty applies if you get an extension but miss the extended date.11Colorado Department of Local Affairs Division of Property Taxation. Filing Requirements
The bigger consequence is what happens to your valuation. If no schedule comes in, the assessor is still required to value your taxable personal property using the “best information available.” The assessor is not allowed to intentionally overvalue the property, but you lose the chance to present your own cost data and depreciation history.12Assessors’ Library. Chapter 3 – Valuation Procedures Estimates made without your input tend to be less favorable than values you could have documented. Filing on time is the simplest way to control the number.
Paying the Bill and What Happens If You Don’t
The filing date and the payment date are separate. You file the schedule with the assessor by April 15, but you pay the resulting bill to the county treasurer later in the year, after the valuation is finalized and the bill is mailed. Colorado property taxes are generally payable in two installments (roughly late February and mid-June) or as a single payment by the end of April, with exact dates set by each county treasurer.
If personal property taxes go delinquent, the county treasurer can start enforcement on October 1. Options include a court action, a collection agency, or a distraint warrant that allows the sheriff to seize and sell the property at public auction to satisfy the debt.13Justia. Colorado Revised Statutes Title 39 – Section 39-10-111 – Distraint Warrant These tools are rarely used for routine delinquencies, but the authority is real.
How to Protest a Valuation
If you think the assessor’s number is too high, Colorado has a set protest calendar. The assessor mails a Notice of Valuation for personal property no later than June 15. You then have until June 30 to file a written protest or appear in person before the assessor. The assessor must respond in writing by July 10, including a justification for the decision.14Colorado Department of Local Affairs Division of Property Taxation. Protests and Appeals
If the response doesn’t satisfy you, appeal to the County Board of Equalization by July 20. The Board holds hearings and must render its decision by August 5. Beyond that, three routes remain: binding arbitration, an appeal to the state Board of Assessment Appeals, or filing in district court.14Colorado Department of Local Affairs Division of Property Taxation. Protests and Appeals
Most personal property disputes get resolved at the assessor hearing if you bring solid documentation of your original costs and the condition of the equipment. Businesses that struggle in these protests tend to be the ones that didn’t keep good records, which loops back to the value of filing a complete and accurate declaration schedule every year.
