Colorado Business Personal Property Tax: Who Must File, April 15 Deadline and the $56,000 Exemption

If your business owns equipment, furniture, tools, supplies or signs, those items may be taxable in Colorado. The county where you own them assesses the property, and the local taxing authorities in that county levy the tax. Many new owners never hear about this until a notice arrives or the assessor asks why nothing was filed. This guide covers who has to file, how the exemption works, when the declaration is due and what it costs to stay compliant. The filing itself costs nothing, but skipping it can get expensive.

What Business Personal Property Covers

Colorado separates property into real property, such as land and buildings, and personal property, which is movable. Business personal property (BPP) is the movable property your business uses to operate. Typical examples include:

• Machinery, equipment and tools
• Office furniture and fixtures
• Supplies on hand
• Signs
• Other movable items used in the business

Land and buildings are a separate category and are not reported on the business personal property declaration. The rule applies to the property itself, not to your entity type, so a sole proprietorship, an LLC and a corporation face the same test.

Who Must File

You file only if you own taxable business personal property in a Colorado county on the January 1 assessment date. What matters is what you own on January 1, not what you bought or sold during the year. Equipment you purchase in June is first reported on the declaration for the following year, provided you still own it on the next January 1. Equipment you sell before January 1 does not appear on that year's declaration.

The test is applied county by county. If you own property in more than one county, each county's assessor looks at the property located there. Confirm with each county where you have property, because the exemption and the filing requirement depend on the local assessor.

The $56,000 Exemption

If the combined actual value of your personal property in a county is $56,000 or less for tax years 2025 and 2026, you do not need to file a declaration schedule for that county. "Actual value" is the assessor's valuation concept, which may differ from what you paid for the equipment, so ask your assessor how they value business equipment if your figures are close to the line.

The exemption amount is indexed every two years and published by the Colorado Division of Property Taxation, with the figures reflected on state and county assessor pages. Because the amount changes, do not assume $56,000 applies to tax years after 2026. Check the figure for the year you are filing.

Denver's assessor page also refers to a $52,000 threshold for new small businesses. Before you assume you are exempt, confirm with your assessor which threshold applies to your business.

The April 15 Deadline

Owners must submit the business personal property declaration schedule to the county assessor no later than April 15 under C.R.S. 39-5-108. The January 1 assessment date sets what goes on the form, and April 15 is the filing date that follows it.

The 2026 filing deadline has already passed. The next deadline is April 15, 2027, for property you own in that county on January 1, 2027. Do not wait for a reminder. Assessors' notice practices vary, and the filing obligation applies whether or not you receive a letter.

Requesting an Extension

If you need more time to assemble your inventory, you can request an extension in writing before April 15. You may ask for 10 or 20 days. The fee is $2 per day requested, which means $20 for 10 days or $40 for 20 days, under C.R.S. 39-5-116. Send the request before the deadline, keep a copy and confirm with the assessor's office how they want it submitted, since submission methods vary by county.

Late Filing and Penalties

If you file late, the penalty under C.R.S. 39-5-116 is $50 or 15 percent of the tax due, whichever is less. That is the smaller of two figures, so the penalty is capped at $50 regardless of how large your tax bill is.

The bigger risk is failing to disclose property at all. If you do not report taxable property, the assessor may value it using the best information available and add a penalty of up to 25 percent on the omitted property. An assessor's estimate is rarely in your favor, so an accurate, timely filing is almost always the better choice.

Why Your Bill Varies by County

Tax rates and assessment percentages vary by county and tax district. Two businesses with identical equipment in different counties can owe different amounts. Filing costs $0, but the tax bill does not, and the filing itself does not tell you what you will owe. Check with your county assessor and treasurer for the current rate and assessment percentage that applies to your tax district. Do not use a neighboring county's figures.

How to File, Step by Step

1. Identify every Colorado county where you had taxable business personal property on January 1.
2. Build an inventory of that property as of January 1, listing equipment, furniture, tools, supplies and signs with their cost and purchase dates.
3. Estimate the combined actual value of the property in each county and compare it with $56,000 for the applicable tax year, confirming the threshold with the assessor.
4. If the exemption does not cover you, find the declaration schedule on your county assessor's website. Forms differ by county. El Paso and Weld counties use Form DS 056, but other counties use their own forms, so do not assume DS 056 applies to you.
5. Complete the schedule and submit it no later than April 15, using the method your assessor accepts.
6. Keep copies of the declaration, your January 1 inventory and any extension request or confirmation.

Common Mistakes to Avoid

• Assuming one exemption covers every county. The $56,000 threshold is measured within each county, so property spread across several counties can require filings in some and not others.
• Miscounting the January 1 date. Equipment bought after January 1 is not on that year's declaration, and equipment sold before January 1 is not on it either.
• Skipping a free filing. The declaration costs nothing, but omitting property can bring penalties and an estimated valuation.
• Sending BPP paperwork to the wrong agency. Business personal property is handled by the county assessor. The Secretary of State handles entity formation and filings such as the Periodic Report, and the Department of Revenue handles state tax accounts such as sales tax. Neither takes the county BPP declaration.
• Using last year's threshold. The exemption is indexed, so confirm the amount for the year you are filing.

Official Resources

• Your county assessor: Find the assessor's office through your county government website. The assessor sets local forms, submission methods and practices.
• Colorado Department of Revenue, Taxation Division: tax.colorado.gov. Use this site for state tax accounts and questions. It does not replace the county BPP declaration.
• Colorado Small Business Development Center (SBDC) Network: sbdc.colorado.gov. Useful for working through recordkeeping and planning questions for your business.
• U.S. Small Business Administration, Colorado district: sba.gov/district/colorado.

Final Checklist

Before April 15, confirm that you have a January 1 inventory for every county where you own movable business property, that you have compared each county's total with the applicable exemption, and that you have confirmed the threshold, rate and form with the right assessor. If any of those steps leaves you unsure, ask the assessor directly. A short phone call costs far less than a penalty on omitted property.
