HB 26-1233 revises Colorado property tax procedures for nonresidential properties, with a focus on valuation appeals and the accuracy of information submitted in those proceedings. The bill authorizes counties to require nonresidential property owners to provide valuation-related information to assessors and local review bodies, and it creates new civil and criminal consequences for failing to provide that information or for willfully submitting false information beginning with property tax years on or after January 1, 2026. It also makes it a petty offense to knowingly file or assist in filing false or fraudulent information connected to nonresidential property valuation, and it authorizes county attorneys to prosecute those cases in county court.
The bill also changes the appeal process for nonresidential property tax disputes. For appeals filed with the Board of Assessment Appeals, a county may ask that the case be moved to district court under specified conditions, while preserving the appeal’s de novo character. In addition, the bill directs the Board of Assessment Appeals or district court to consider changes in valuation information submitted by the petitioner when evaluating evidence and credibility. It further provides that if a court or the board finds the owner changed disclosed information, intentionally delayed the process, or intentionally provided false information, the owner forfeits the right to receive penalty interest on any tax refund.
In practical terms, the bill amends several sections of Colorado property tax law, including provisions governing taxpayer information, hearings on appeal, appeal rights, and penalty interest on delinquent taxes. It applies specifically to nonresidential property and affects property owners, county assessors, county boards of equalization, county boards of commissioners, the Board of Assessment Appeals, district courts, and county attorneys. The measure is designed to strengthen disclosure requirements, deter misinformation, and give counties more procedural leverage in certain commercial-property valuation disputes.
The overall sentiment reflected in the bill’s structure is supportive of tighter enforcement and more efficient resolution of nonresidential property tax disputes. Although no committee transcript or recorded vote details are provided, the bill’s passage and signing suggest it advanced without documented public controversy in the available record. Its emphasis on penalties for false statements and on shifting some appeals to district court indicates a policy preference for greater accountability from commercial property owners and more tools for counties to challenge disputed valuations.
The main points of potential contention are likely to be the new penalties and the county’s ability to seek transfer of an appeal from the Board of Assessment Appeals to district court. Property owners may view the false-information offense and loss of interest on refunds as punitive, while counties and assessors may support them as necessary to prevent abuse and improve valuation accuracy. Another possible concern is that the bill could increase litigation complexity or costs in nonresidential property appeals, especially where parties dispute whether information changed, whether delay was intentional, or whether the criteria for transfer to district court are met.
The bill amends Colorado property tax statutes governing nonresidential property valuation appeals, taxpayer disclosure obligations, and refund interest. It adds a petty offense for willfully false or fraudulent valuation-related submissions, allows county attorneys to prosecute those cases, permits counties to seek transfer of certain Board of Assessment Appeals cases to district court, and authorizes forfeiture of penalty interest on refunds when a court finds misconduct by the taxpayer. These changes apply to property tax years beginning on or after January 1, 2026, and primarily affect commercial and other nonresidential property owners, county tax officials, and appeal tribunals.
The available record suggests generally favorable sentiment toward the bill, with no recorded committee testimony or vote breakdown indicating organized opposition. The bill’s enactment and signing imply it was viewed as a targeted enforcement and procedure measure rather than a broad tax increase. Its design reflects support for stronger county authority and stricter consequences for inaccurate disclosures in nonresidential property tax disputes.
The likely areas of contention are the new petty offense for false information, the potential forfeiture of refund interest, and the county’s ability to request that an appeal be heard in district court. Critics could argue these provisions increase pressure on property owners and add procedural complexity, while supporters would likely say they deter manipulation and improve fairness in valuation appeals. The bill also raises questions about how courts will assess whether a taxpayer intentionally delayed proceedings or knowingly submitted false information, which could become a disputed factual issue in individual cases.
