Rate Breakdown

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

How Property Tax Works in Graham County

Graham County, Arizona, levies property taxes based on the assessed value of real and personal property located within the county’s jurisdiction. The assessment process begins each year when the County Assessor’s Office determines the market value of every taxable parcel. This market value is then multiplied by the state‑mandated assessment ratio (generally 10 % for residential property) to arrive at the assessed value that will be used for tax calculations.

Once the assessed value is established, the county applies the appropriate millage rates. A millage rate is expressed in “mills,” where one mill equals one‑tenth of one percent (0.001). For example, if the total combined millage rate for Graham County is 30 mills, a property with an assessed value of $150,000 would owe:

• Assessed value: $150,000 × 10 % = $15,000
• Tax due: $15,000 × 0.030 (30 mills) = $450

Millage rates are set annually by the County Board of Supervisors, the school district, and any special districts (fire, water, road maintenance). The posted rates for the current fiscal year can be viewed on the Graham County Treasurer’s website.

Available Exemptions

Arizona offers several property‑tax exemptions that can reduce the taxable portion of your assessed value. Graham County administers these exemptions in accordance with state law.

• Homestead Exemption: Residents who occupied the property as their primary residence as of January 1 may qualify for a $250 exemption on the assessed value.
• Senior Citizen Exemption: Homeowners age 65 or older may receive an additional $250 exemption, provided they meet income eligibility (gross income not exceeding $30,000 per year).
• Disability Exemption: Qualifying disabled individuals (or their spouses) can claim a $250 exemption. Documentation from a licensed physician or the Arizona Department of Economic Security is required.
• Veteran Exemption: Eligible veterans or surviving spouses can obtain a $250 exemption for service‑connected disabilities, and an additional $500 exemption for 100 % disabled veterans.

Exemptions are applied automatically when you file the appropriate claim forms with the Assessor’s Office by the annual deadline (usually March 1). Missing the deadline may postpone the benefit until the following tax year.

Payment Schedule & Deadlines

Graham County property taxes are due in two installments:

• First installment: Due on October 1. If paid by this date, only a 5 % discount is applied to the total tax bill.
• Second installment: Due on March 1 of the following year. Taxes not paid by this second deadline incur a 5 % penalty plus interest at the state‑prescribed rate.

Taxpayers may also opt for monthly payments through the county’s online portal, which spreads the liability over twelve equal installments. Late payments after March 1 result in a 10 % penalty, and the debt may be placed in a tax lien, potentially leading to a tax sale if unresolved.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, Graham County provides a formal appeals process:

• Step 1 – Informal Review: Contact the Assessor’s Office within 30 days of receiving the assessment notice. Provide supporting evidence (recent sales, appraisals, repair invoices) to request a reconsideration.
• Step 2 – Formal Appeal: If the informal review is denied, you may file a written appeal with the Arizona Board of Equalization (ABE) within 30 days of the denial. Include all documentation, a copy of the assessment notice, and the completed appeal form.
• Step 3 – Hearing: The ABE will schedule a hearing where you can present your case in person or via video conference. An independent appraiser may be appointed to conduct a new valuation.
• Step 4 – Decision: The Board issues a written decision, which is final unless appealed further to the Arizona Court of Appeals within 30 days.

Throughout the process, keep copies of all correspondence and maintain a clear paper trail. The Graham County Assessor’s Office also offers a free “pre‑assessment consultation” to help taxpayers understand their rights and gather the necessary evidence before filing an appeal.
