1
Start with schedule number when available
It is the cleanest way to avoid wrong-property mistakes.
▾
Use the schedule number from your statement, closing paperwork, escrow notice or prior receipt. Match the property address and owner before relying on the result.
2
Use Assessor search for value and property facts
This is not the same as the payment screen.
▾
Open the free Larimer County Property Search. Use it for property characteristics, classification, actual value, sales, mobile home data, residential/commercial/agricultural records and public data.
3
Use Treasurer search for money questions
Balance, receipt and delinquency belong to Treasurer.
▾
Open the Treasurer tax calculator/payment search for current balance, payment options, tax statement, delinquent status and receipts.

1
Open the official Treasurer payment search
Do not start from an unrelated payment ad.
▾
Go to the Larimer County Treasurer payment / tax calculator page. Confirm the property, schedule number, tax year, installment and balance.
2
Choose the lowest-risk payment method
Fee and timing matter near deadlines.
▾
E-check is listed with no fee. Card payments have a 2.3% convenience fee. Bank bill pay may take up to two weeks for processing and mailing, so do not use it close to deadlines unless you have enough time.
3
Include the schedule number
Missing schedule numbers cause posting problems.
▾
If mailing or using bank bill pay, include your property’s schedule number to ensure proper posting. If you do not have the payment coupon, write the schedule number clearly on the check or bill-pay memo.
4
Save receipt and verify posting
Especially important for escrow, sale or refinance.
▾
Save the payment confirmation, receipt number, amount, schedule number and tax year. If you receive a delinquent notice after paying, the Treasurer recommends checking the property tax calculator for current balance or calling the office.
How to calculate a Larimer County property tax estimate
Use the estimate only for planning. Your official tax statement and Treasurer balance control the final amount, due dates and payment status.
Colorado-style property tax estimate
Estimated tax = actual value × assessment rate × mill levy ÷ 1,000, minus eligible exemptions or credits, plus any fees, interest or special charges.
| Bill Factor | What It Means | Where To Check |
|---|---|---|
| Actual value | Assessor’s value of the property. | Assessor Property Search. |
| Assessment rate | Colorado rate applied by property class. | Assessor assessment rate resources. |
| Mill levy | Local district tax rate. | Tax statement / Treasurer record. |
| Exemptions | Senior, qualifying veteran, Gold Star Spouse or other relief. | Assessor exemption page. |
| Delinquent interest | Added if payment is late. | Treasurer current balance. |
High tax bill, escrow issue, missing exemption or value protest
A high tax bill can come from value, assessment rate, mill levy, special district changes, exemption status, escrow mistakes or delinquent balance. Start by finding the line that changed.
| Problem | Call / Use First | What To Prepare |
|---|---|---|
| Actual value looks too high | Assessor — 970-498-7050 | Comparable sales, photos, property condition, property record errors, appraisals. |
| Classification looks wrong | Assessor | Use type, agricultural documentation, mobile/manufactured home info, business use details. |
| Payment not posted | Treasurer — 970-498-7020 | Receipt, confirmation, payment date, schedule number, bank/card record. |
| Mortgage company should pay | Mortgage servicer, then Treasurer | Escrow statement, tax statement, schedule number, lender disbursement date. |
| Senior / veteran exemption missing | Assessor exemption page | Eligibility documents, ownership/occupancy proof, forms, deadline check. |
| Formal protest | Assessor protest process | Evidence filed during the May 1-June 8 window for 2026 if applicable. |
1
Compare value, mills and exemptions separately
Do not compare only the final dollar total.
▾
Check actual value, assessment rate, mill levy, exemptions, special assessments, prior balance and interest. A higher bill may be caused by more than one line item.
2
Use the correct office
Treasurer cannot reduce assessed value.
▾
Larimer County explains that the Treasurer collects taxes and disburses funds but does not determine the tax amount. Contact the Assessor for property value or classification questions.
3
Watch the protest window
Payment deadlines and protest deadlines are different.
▾
For 2026, Larimer County Assessor FAQ says property owners can file a protest from May 1 through June 8 by mail, online tool, in person, appointment, fax or outdoor drop box. Always verify the current tax-year window.
Senior, veteran, Gold Star Spouse and tax assistance options
Tax relief is deadline-driven. Verify requirements before assuming you qualify or before missing a filing date.

The Veteran with a Disability and Gold Star Spouse exemption deadline shown for 2026 closed July 1, 2026. Verify future-year windows early.
