Rate Breakdown

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

How Property Tax Works in La Paz County

Every year the La Paz County Assessor’s Office reviews the market value of each taxable parcel and assigns a “assessed value.” In Arizona the assessed value is 10 % of the property's full market value, unless a special assessment or exemption applies. This assessed value becomes the base for calculating the tax bill.

County tax collectors then apply the appropriate millage rates – the amount of tax per $1,000 of assessed value. La Paz County’s total millage rate typically includes:

• County general fund (approximately 5.5 mills)
• Fire district, water & sewer districts, and other special districts (varies by location)
• School district levies (around 9 mills)
• Any voter‑approved bonds or supplemental levies

Multiply the assessed value (in thousands) by the combined millage rate to estimate the annual tax amount. For example, a home with a market value of $200,000 has an assessed value of $20,000. If the total millage rate is 15 mills, the tax bill would be $20,000 ÷ 1,000 × 15 = $300.

Available Exemptions

Arizona law provides several exemptions that can lower the assessed value before the millage rate is applied. La Paz County honors all state‑wide exemptions, and eligible owners should file the appropriate claim forms with the Assessor.

• Homestead Exemption – Reduces the taxable value of a primary residence by $2,500. The exemption is automatic for owner‑occupied homes, but an application may be required for verification.
• Senior Citizen Exemption – Available to owners aged 65 or older whose total household income does not exceed the state‑defined limit. The exemption reduces the assessed value by up to $3,000.
• Disabled Person Exemption – Qualifies individuals with a permanent disability. The exemption amount mirrors the senior exemption and is also based on income eligibility.
• Veteran Exemptions –
  • Disabled veterans receive a $2,000 exemption for each 10% of disability rating.
  • Surviving spouses of veterans killed in action receive a $4,000 exemption.

All exemption applications must be filed by the May 1 deadline for the tax year in which you seek relief.

Payment Schedule & Deadlines

La Paz County collects property taxes semi‑annually. The typical schedule is:

• First installment – Due September 15. This payment covers the October 1–March 31 portion of the fiscal year.
• Second installment – Due December 15. This payment settles the April 1–September 30 portion.

Taxpayers may also elect to pay the full amount in a single payment by September 15, which can simplify record‑keeping and avoid the second‑installment due date.

Late payments incur a 5 % penalty plus interest calculated at the state‑prescribed rate. If a bill remains unpaid after the second installment deadline, the County Treasurer may place a tax lien on the property, potentially leading to tax foreclosure.

Appealing Your Assessment

If you believe your property has been over‑assessed, you have the right to contest the value. The appeal process in La Paz County follows Arizona’s statutory timeline:

1. Request a Review – Submit a written Request for Review to the La Paz County Assessor’s Office within 30 days of receiving the notice of assessed value.
2. Attend a Hearing – The Assessor’s Review Board will schedule a hearing, typically within 45 days of the request. Bring comparable sales data, recent appraisals, or any evidence supporting a lower value.
3. Decision – The Review Board issues a written decision within 30 days of the hearing. If the decision is unfavorable, you may appeal to the Arizona State Board of Equalization within 30 days of receiving the Board’s ruling.

Preparation is key: gather recent sales of similar properties, any documentation of property damage, and a clear calculation of the market value you believe is correct. Professional appraisals, while not required, can strengthen your case.

Remember, the appeal must be filed before the tax bill’s final due date; otherwise, the assessed value becomes final for that tax year.
