Rate Breakdown

Property taxes in Greenlee County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Greenlee County

Greenlee County assesses property value annually on January 1. The County Assessor determines the market value of land and any improvements (such as a house, garage, or commercial structure) by comparing recent sales of similar properties, cost‑approach data, and income‑producing potential where applicable. Once the market value is established, the Assessor applies the statutory “assessment ratio” of 100 % for residential and commercial properties (Arizona does not reduce the assessed value for tax purposes).

The resulting assessed value is multiplied by the county’s combined millage rate to calculate the yearly tax bill. A “mill” represents one‑tenth of one cent, or $1 of tax per $1,000 of assessed value. For the 2024‑25 fiscal year, Greenlee County’s total millage (including the County, the City of Clifton, school districts, and special districts) was approximately 38.75 mills. That means a property assessed at $200,000 would owe roughly $7,750 in taxes before any exemptions are applied.

Available Exemptions

Arizona offers several statutory exemptions that reduce the taxable portion of a property’s assessed value. In Greenlee County, eligible owners can claim the following:

• Homestead Exemption: Reduces the taxable value of a primary residence by up to $150,000. To qualify, the owner must occupy the property as their principal dwelling on or before January 1 of the tax year.
• Senior Citizen Exemption: Residents aged 65 or older may receive an additional $10,000 reduction (or $15,000 if the senior’s income is below a set threshold) on the assessed value of their homestead.
• Disability Exemption: Qualified persons with a documented disability can claim a $15,000 reduction on their homestead’s assessed value. Verification must be provided through a physician’s statement and a disability determination from the Arizona Department of Economic Security.
• Veteran Exemption: Veterans who served at least 90 days of active duty during wartime, or who have a service‑connected disability, may receive a $15,000 exemption on their primary residence. Surviving spouses of deceased veterans also qualify.

Exemptions are applied automatically for some categories (e.g., senior and disabled) after the Assessor receives the necessary documentation. Others, like the homestead exemption, require the owner to file a claim with the County Assessor’s Office by the due date of the tax bill.

Payment Schedule & Deadlines

Greenlee County follows the standard Arizona property‑tax calendar:

• First installment: Due November 1 (or the first business day after, if November 1 falls on a weekend/holiday). The deadline for this payment is December 31.
• Second installment: Due May 1, with a deadline of June 30.
• Late penalties: If a payment is not received by the deadline, a 10 % penalty is assessed on the overdue amount, plus interest at the rate set by the Arizona Department of Revenue.
• Installment options: Taxpayers may elect to pay the full amount early, split the two installments, or set up an automatic bank‑draft (ACH) through the county’s online portal.

Paying early reduces the risk of penalties and may qualify the owner for a modest discount if the county’s e‑payment system offers a “pay‑early” incentive. All payments can be made online, by mail, or in person at the Greenlee County Treasurer’s Office.

Appealing Your Assessment

If you believe the Assessor’s valuation is inaccurate, you have the right to contest it. The appeal process in Greenlee County proceeds as follows:

• File a petition: Submit a written appeal to the Greenlee County Board of Equalization within 30 days of receiving the notice of assessment (the “Notice of Equality”). The petition must include a description of the property, the assessed value, and the grounds for disagreement.
• Provide evidence: Attach comparable sales data, recent appraisals, or repair cost estimates that support your claim. Photographs and a detailed property description strengthen the case.
• Board hearing: The Board will schedule a public hearing, typically within 45 days of filing. You may present your evidence, and the Assessor may respond.
• Decision: The Board issues a written decision, which can either adjust the assessment or uphold it. If unsatisfied, you may appeal further to the Arizona Tax Court within 30 days of the Board’s ruling.

Engaging a licensed appraiser or property tax consultant can improve the likelihood of a favorable outcome. Timely filing and thorough documentation are essential to a successful appeal.
