Property Tax Proceedings for Nonresidential Property
Summary
HB1233 makes several changes to Colorado’s property tax procedures for nonresidential property, with most provisions taking effect for property tax years beginning on or after January 1, 2027. The bill creates a petty offense for anyone who willfully submits false or inaccurate information required in connection with nonresidential property tax filings, and also for anyone who willfully aids or advises the preparation or presentation of fraudulent or false information. It limits criminal liability to the person who actually files or assists in filing the false information and authorizes county attorneys to prosecute these cases in county court.
The bill also changes appeal procedures for nonresidential property valuation disputes. It allows a county, after a nonresidential property owner appeals to the Board of Assessment Appeals, to file a motion expressing a preference that the case be heard in district court, while preserving the Board of Assessment Appeals’ jurisdiction unless the taxpayer chooses to withdraw and proceed in district court. In addition, it clarifies data-exchange requirements in valuation appeals and preserves the existing framework for appeals, arbitration, and disclosure of assessor valuation data.
HB1233 further amends the tax-payment statute to provide that a taxpayer convicted of the new petty offense forfeits entitlement to penalty interest, and it specifies that the Board of Assessment Appeals cannot decide whether that forfeiture applies; only a court in the criminal prosecution may make that determination. The bill therefore links false-information penalties to tax consequences and reinforces county-level enforcement authority.
The overall sentiment reflected in the voting history is supportive but not unanimous. The bill passed committee and floor votes in both chambers, but several votes were close, especially in House Finance and on third reading in both chambers, indicating some hesitation about the policy changes. Final concurrence votes were stronger, suggesting that amendments helped secure broader agreement.
The main points of contention appear to be the bill’s tougher treatment of nonresidential property owners and their representatives in valuation disputes, especially the new criminal penalty for misinformation and the county’s ability to push for district court rather than the Board of Assessment Appeals. Supporters likely viewed the bill as improving accuracy and fairness in property tax administration, while opponents may have been concerned about added enforcement, litigation pressure, and the potential chilling effect on appeals.
Impact
HB1233 amends Colorado property tax statutes governing nonresidential property by adding criminal penalties for willful false statements in required filings, adjusting appeal procedures for valuation disputes, and tying certain tax-interest consequences to convictions under the new offense. It affects property owners, tax representatives, county assessors, county attorneys, and the Board of Assessment Appeals, while leaving the existing appeal structure in place but adding a county motion procedure and clarifying evidence-exchange and enforcement rules.
Sentiment
The bill appears to have received generally favorable treatment overall, as it advanced through both chambers and ultimately achieved concurrence on Senate amendments. However, the vote margins show meaningful opposition at several stages, particularly in House Finance and on third reading, suggesting that while many legislators supported the bill’s goals, a significant minority had reservations about its enforcement provisions and procedural changes.
Contention
The most notable contention centers on the bill’s new petty offense for false or misleading information tied to nonresidential property tax filings and the role of county attorneys in prosecuting those cases. Another point of debate is the new county motion process that signals a preference for district court when a taxpayer appeals to the Board of Assessment Appeals, which some may view as shifting leverage toward counties and potentially complicating taxpayer appeals. The forfeiture of penalty interest upon conviction also raises concern because it adds a financial consequence beyond the criminal penalty itself.
