The Larimer County Treasurer & Public Trustee’s Office announces that delinquent property tax statements for the 2024 tax year, payable in 2025, will begin arriving in mailboxes this week.

Property owners who made payments after July 10, 2025, may still receive a delinquent notice due to processing and mailing timelines.

Treasurer & Public Trustee Irene Josey reminds residents that delinquent interest began accruing on April 30 for property owners who have not made any payments. Those who submitted a first-half payment but missed the second-half deadline began accruing interest as of June 16. Interest accrues at a rate of 1% per month or any part of a month, as outlined in Colorado Revised Statutes.

All mortgage company payments have been processed and posted.

The Larimer County Tax Lien Sale is scheduled for November 20, 2025.
