Property Taxes become due on January 1 for the previous year. Payments may be paid in two equal installments or in one full installment; partial payments are not accepted.

  • FIRST HALF: March 2, 2020 (NOTE: Updated 4/7/20, delinquent interest has been waived for first half payments through April 30, 2020, including postmarks. Read more here).
  • SECOND HALF: June 15, 2020
  • FULL PAYMENT: April 30, 2020

If the total property tax amount is $25.00 or less, the half-payment option is not allowed, therefore a single payment must be postmarked by the full payment due date referenced above.

Certified funds in the form of cashier's checks or money orders are REQUIRED for all payments beginning September 1.

If your payment is postmarked after the due dates referenced above, your payment may be rejected and delinquent interest will be added to the tax amount.

Current taxes may be paid with your online banking service. Make sure to include your tax schedule number with the payment. Please allow two weeks for processing and mailing of the payment to our office. Take this delay into account for tax payments near our deadlines. Payments not received timely will be returned and additional interest will be due.

Changes of address are processed by the Larimer County Assessor's Office and they must be notified in writing containing the owner's signature. Mail to:

Colorado Revised Statutes mandate that the Treasurer mail the Property Tax Statement to the owner of record, as their name and address are listed on the Tax Roll certified by the County Assessor. Therefore, your mortgage company does not receive a copy of the Property Tax Statement. Most mortgage companies perform their own research on the property taxes they are responsible for by your contractual agreement. If you feel your mortgage company needs a copy of your Property Tax Statement, simply send them a photocopy or contact the Treasurer's Office for an additional copy. The fee is $2.00.

If you and your mortgage company submit payment, the Treasurer will process the first payment received and return the subsequent payment to the paying party. The Treasurer does not hold or apply additional monies. For further mortgage company payment information contact the Treasurer's Office at (970) 498-7020, or via email.
