Arizona Property Taxes Explained — LPV, Ratios and the 1% Cap

Arizona property taxes are, by national standards, generally on the modest side — which is part of what draws people here. But the system that produces the number is genuinely unusual, and understanding it explains why your bill behaves the way it does.

Here is how it actually works.

Two values, not one

Every Arizona parcel carries two different values, and confusing them is the most common source of misunderstanding:

Value	What it is	What it drives
Full cash value (FCV)	Roughly market value, as the assessor estimates it	Secondary taxes
Limited property value (LPV)	A statutorily restricted value	Primary taxes

The key point: LPV growth is limited by statute. It cannot simply track a hot market upward year over year. That is why Arizona homeowners did not see their tax bills double during the 2020–2022 price surge, even as their homes' market values climbed sharply.

It also means your tax bill is not a good proxy for what your home is worth, and your home's value is not a good proxy for your tax bill.

The assessment ratio

Your rate is not applied to the whole value. It is applied to the assessed value, which is a percentage of the property's value determined by how the property is classified.

For residential property, that ratio is 10%. Commercial and other classes are assessed at higher ratios, which is one reason a commercial parcel and a house of the same nominal value carry very different bills.

So the rough sequence is:

1. The assessor establishes FCV and LPV for the parcel
2. The applicable value is multiplied by the assessment ratio (10% for residential)
3. Tax rates from each overlapping jurisdiction are applied to that assessed value
4. The results are summed into one bill

Primary vs secondary taxes

Arizona splits property tax into two buckets, and they behave differently:

• Primary taxes fund general operations — county, city, school district maintenance and operations. These are calculated on LPV and are the ones subject to the cap below.
• Secondary taxes fund voter-approved bonds, budget overrides, and special districts (fire districts, flood control, community facilities districts, and similar). These are calculated on FCV and sit outside the cap.

When two neighbours in the same city have noticeably different bills, secondary levies are very often the reason.

The 1% constitutional cap

The Arizona Constitution limits primary property taxes on an owner-occupied residence to 1% of the property's limited property value. Where the combined primary rates would exceed that, the excess is not simply charged to the homeowner.

This is a meaningful protection, and it is specific to owner-occupied residential property. Note carefully what it does not do:

• It does not cap secondary taxes
• It does not cap your total bill
• It does not apply to investment property you do not occupy

So "taxes are capped at 1%" is true in a precise, limited sense, and misleading if repeated without the qualifiers.

Owner-occupied classification is worth checking

Arizona distinguishes owner-occupied residential property from rental residential property, and the classification affects how the parcel is treated. If you buy a home that was previously a rental and move into it, it is worth confirming with the county assessor that the classification has been updated. This is an easy thing to overlook in the first year of ownership and an easy thing to correct.

Why bills vary so much between similar homes

Parcels sit inside overlapping jurisdictions, and each adds a levy:

• County
• City or town (or unincorporated county area)
• School district — often the single largest component
• Community college district
• Fire district, in unincorporated areas
• Flood control, library, and other special districts
• Community facilities districts in some newer master-planned developments

Cross one boundary and the arithmetic changes. This is why a house in Gilbert and a house in Chandler with identical market values can carry different bills, and why two houses in the same subdivision occasionally do too.

That last one matters for new-build communities. Some carry a community facilities district levy that funds the infrastructure of the development itself. It is legitimate and disclosed — but it is an ongoing cost that a buyer comparing against an established neighborhood may not have factored in.

What to actually do before you buy

1. Look up the specific parcel with the county assessor and treasurer. Maricopa County covers most of metro Phoenix; Pinal County covers parts of the southeast Valley including areas around San Tan Valley.
2. Read the current bill, not an estimate. It itemises every levying jurisdiction.
3. Ask whether the community has a CFD if it is a newer master-planned development.
4. Check the classification if the home has been a rental.
5. Do not budget from an averaged rate, including anything in this article. Parcel-level records exist; use them.

If you think your valuation is wrong

Arizona has a formal process for appealing a valuation, with published deadlines that run from the date the notice of value is mailed and are easy to miss. If you believe the assessor's value is out of line with comparable properties, the mechanism is there — but the timing is strict, so read the dates on the notice when it arrives rather than filing it away.

Property tax is one of those costs that is entirely knowable in advance and yet routinely estimated. If you are weighing specific properties and want the real numbers pulled for each — along with what the running costs look like — that is part of the conversation. If you are budgeting a move to Arizona more broadly, the cost of living guide covers the rest of the picture.
