Property Tax Payment Information

Please make your payment to the Larimer County Treasurer, PO Box 1250, Fort Collins, CO 80522. To ensure accurate posting, please include the appropriate payment coupon for each property you are paying taxes for.

Tax Statement Mailing

The Property Tax Statement is mailed by the end of each January, to the owner of record, as listed on the Tax Roll, as of January 1. The Tax Roll is prepared and maintained by the County Assessor.

**Failure to receive a Property Tax Statement does not exempt the taxpayer from timely payment of the taxes due.**

If you have not received a tax statement by the first week of February, please contact the Treasurer's Office at (970) 498-7020 and a duplicate statement will be mailed.

Address Change

The Larimer County Assessor should be notified of any change in the mailing address for each property you own. A change of address must be made in writing and requires an owner's signature. It cannot be done with a telephone call. The Assessor's mailing address is PO Box 1190, Fort Collins, Colorado 80522. You can also use this Change of Address Form.

Property Taxes become due on January 1 for the previous year. Payments may be paid in two equal installments or in one full installment.

Where Do I Make Payments?

Payments may be mailed to the Larimer County Treasurer's Office, PO Box 1250, Fort Collins, CO 80522. To ensure accurate posting, please include the appropriate payment coupon for each property you are paying taxes on and write the schedule number(s) in the memo of your check.

You may also pay directly at our office. We're located on the second floor of the Larimer County Courthouse, 200 West Oak, Fort Collins, CO. Office hours are Monday-Friday, 8 a.m. – 4:30 p.m.

Handicap Access is located at both entrances of the Larimer County Courthouse. The Treasurer's Office is also Handicap Accessible.

**Please bring your tax notice with you. Your tax notice can act as your receipt of your payment at no charge.
The fee for each additional receipt is $2.00.**

Payments may also be made at most Larimer County banks. You must bring your tax statement with you when making payment! Banks will only accept current year payments until July 31.

Mortgage Company Payments

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) 498-7032, or via email
