How Arizona Property Assessment Works
Arizona’s property assessment is unusual because there are two values assigned to every property — and they serve entirely different purposes.
Full Cash Value (FCV)
The Full Cash Value is Arizona’s estimate of the property’s current market value — similar to the “assessed value” concept in other states. It is assessed annually by the Maricopa County Assessor and should approximate what the property would sell for on the open market. This is the value most buyers see when they look up their property on the Assessor’s website.
Limited Property Value (LPV)
The Limited Property Value is a separate, capped value that cannot increase by more than 5% per year under Proposition 117 (passed by Arizona voters in 2012). The LPV is what property taxes are actually calculated on. It starts at or near 100% of FCV when a home is first assessed, but can only grow 5% per year after that.
In fast-appreciating markets like the 2020–2023 Phoenix metro surge, Full Cash Value could increase 20–30% per year while the LPV was capped at 5% — dramatically limiting the tax impact of market appreciation. Long-term homeowners benefit significantly; buyers who purchase at peak values get their LPV reset to current market levels.
How Taxes Are Calculated — Step by Step
Arizona’s property tax calculation is a three-step process that differs from most other states in one critical way: the tax is applied not to the full property value, but to 10% of the LPV. This is the core reason Arizona’s effective tax rates are so low.
This three-step process — LPV → 10% assessment ratio → tax rate applied to the reduced base — is why Arizona homeowners pay significantly less than states where the tax is applied directly to full market value.
Proposition 117 — The 5% Annual Cap
Arizona voters passed Proposition 117 in 2012, capping the annual LPV increase at 5% maximum. This has significant implications for both buyers and long-term owners:
- When you buy a home, your LPV is set at or near the FCV at time of purchase
- Each subsequent year, your LPV can only increase 5% maximum — regardless of how fast the market appreciates
- Long-term homeowners benefit significantly: someone who bought in 2015 at $350K FCV has an LPV that has grown only 5%/year since, even if their home is now worth $700K
- When a home sells, the LPV is reset closer to FCV reflecting the sale transaction — buyers should expect their property tax to be higher than the prior owner’s
Primary vs Secondary Property Taxes
Arizona has two property tax categories that appear as separate line items on your tax bill. Understanding the difference is essential — especially when buying in a new master-planned community.
Primary Taxes
Primary taxes fund county government, cities, and school district operations (M&O — maintenance and operations budgets). They are subject to constitutional and statutory limits on how much can be levied.
- County General Fund
- City or town taxes
- School district M&O (operating budgets, not capital bonds)
Secondary Taxes
Secondary taxes fund voter-approved bonds, special improvement districts, and excess school maintenance levies beyond primary limits. They are not subject to the same levy caps as primary taxes.
- School district bond levies (the most common secondary levy)
- Community Facilities Districts — common in new master-planned communities
- Fire district bonds
- Library district bonds
When you buy a home in a new master-planned community (Morrison Ranch, Power Ranch, Meridian) built using Community Facilities District bonds, the secondary tax can be substantial — $1,000–$3,000+/year on top of the primary tax. Always ask your agent: “Does this property have a CFD or other secondary tax district?” before submitting an offer.
Community Facilities Districts — What New Construction Buyers Must Know
A Community Facilities District (CFD) is a special taxing district used by developers to finance community infrastructure (roads, water, sewer, parks) in new developments. The cost of that infrastructure is repaid by the homeowners over time as an additional property tax overlay.
How CFDs Work
- Developer creates a CFD for a new community
- CFD issues bonds to pay for infrastructure (roads, utilities, parks)
- Homebuyers within the CFD pay an additional annual tax added to the secondary tax bill to repay those bonds — typically over 15–30 years
- CFD tax: $500–$2,500+/year depending on the community and original infrastructure cost
- CFDs expire when the bonds are repaid — after which the additional tax goes away
CFDs in East Valley Communities
| Community | CFD Status | Notes |
|---|---|---|
| Meridian (Queen Creek) | Active CFD | Verify specific annual levy amount on the parcel |
| Harvest (Queen Creek) | Active CFD component | Amounts vary by phase and parcel |
| New Queen Creek developments | Many active CFDs | Confirm per property on Assessor site |
| New San Tan Valley developments | Many active CFDs | Confirm per property on Assessor site |
| Morrison Ranch (original phases) | Bonds may be partially retired | Verify current CFD levy on Assessor site |
| Power Ranch (original phases) | Bonds may be partially retired | Verify current CFD levy on Assessor site |
How to check: Ask your agent, or look up the property on the Maricopa County Assessor website at assessor.maricopa.gov and review all special district tax levies listed on the parcel detail page.
How to Read Your Arizona Property Tax Bill
Arizona property owners receive their Maricopa County property tax bill in two installments:
- First installment: due October 1 (delinquent November 1)
- Second installment: due March 1 (delinquent May 1)
What Appears on Your Tax Bill
| Line Item | What It Means |
|---|---|
| Property Address & APN | Arizona Parcel Number — unique identifier for your property at the county level |
| Full Cash Value (FCV) | The assessor’s current market value estimate — what the property should sell for |
| Limited Property Value (LPV) | The capped value taxes are based on — can be substantially lower than FCV in a rising market |
| Assessed Value | 10% of LPV — the base on which the tax rate is applied |
| Primary Tax Levy | County, city, and school M&O taxes |
| Secondary Tax Levy | Bonds, CFD payments, special district assessments — this is where surprises appear |
| Total Annual Tax | Primary + Secondary combined |
In established neighborhoods where prior owners have held for years, the LPV may be significantly below the FCV due to the 5%/year cap. When a property sells, the LPV is reset toward FCV. This means new buyers will often see higher property taxes than the prior owner paid — sometimes substantially higher — beginning with the first full assessment cycle after purchase.
How to Appeal Your Arizona Property Tax Assessment
If you believe your assessed value (FCV) is incorrect — either too high, or not reflecting actual market conditions — Arizona provides an appeal process. Given that the LPV is derived from FCV, a successful FCV appeal can reduce your tax bill over time.
Appeal Timeline
- Notices of Value are mailed February/March each year
- Appeal deadline: typically 60 days from the notice of value date (verify your specific notice)
- Appeal venue: Maricopa County Assessor’s Office (initial petition), then the Property Tax Oversight Commission or Superior Court if unresolved
How to Build a Successful Appeal
- Gather recent comparable sales within the past 12 months — similar properties in the same neighborhood or zip code
- Document any condition issues not reflected in the assessment: structural problems, deferred maintenance, flood zone location
- Compare the Assessor’s FCV to your purchase price if you bought recently — if you paid less than FCV, the sale itself is compelling evidence
- Submit the appeal form to the Maricopa County Assessor’s Office with your comparable sales documentation
- Most successful appeals present 3–5 clearly comparable closed sales at values below the Assessor’s FCV
-
Proposition 117 limits the urgency of FCV appeals in a rising market. Even if the FCV is slightly high, the LPV (which taxes are based on) may already be significantly lower due to the 5%/year cap. In a rapidly appreciating market, the LPV can be 15–30% below FCV — meaning the tax impact of an inaccurate FCV is muted until the LPV catches up.
-
Recent buyers have the strongest appeal cases. If you closed on a property and the Assessor’s FCV exceeds your documented purchase price, the transaction itself is the best comparable — you can appeal immediately after purchase based on the recorded sale.
-
Most appeals are handled without legal counsel. The Maricopa County process is designed to be accessible. Bring your comparable sales printouts and a copy of your closing disclosure if you bought recently, and the process is straightforward for most residential cases.
What Buyers Should Know Before Closing
Arizona’s property tax system has specific implications for buyers that don’t apply in other states. Here is what to verify before you close:
- Request the prior year property tax amounts as part of due diligence — these are public record and your agent can pull them from the Maricopa County Assessor
- Check for any CFD or special district overlays — particularly in master-planned communities in Queen Creek, Gilbert, Chandler, and San Tan Valley
- Verify the lender impound amount matches the current year’s expected tax bill — lenders sometimes impound based on the prior owner’s lower LPV-capped rate, which will be insufficient
- Expect a tax increase in your first full year of ownership — after purchase, the LPV is adjusted at the next assessment cycle to reflect the sale price
- Compare the Assessor’s FCV to your purchase price — if the FCV exceeds what you paid, you may be able to file an immediate appeal based on the documented transaction
On a $600,000 home: Arizona (effective ~0.63%) costs approximately $3,780/year in property taxes. Texas (effective ~1.8%) costs approximately $10,800/year — a $7,020 annual difference. Illinois (effective ~2.23%) costs approximately $13,380/year — a $9,600 annual difference. For buyers relocating from Texas or Illinois, Arizona’s lower property taxes meaningfully offset the cost of living comparison.
