Maricopa Tax Assessment Search: FCV, LPV & Property Values

Search the Parcel, Decode the Value, Follow the Tax Trail

Search Maricopa County property assessments by Assessor Parcel Number, owner name or street address, then read the record correctly: Full Cash Value is the market-oriented value, Limited Property Value is usually the taxable value base, and the legal class determines the assessment ratio.

This guide goes beyond a basic lookup. It shows the exact search syntax, why Arizona sends a 2027 valuation notice during 2026, what a 10% residential assessment ratio actually means, how Rule A and Rule B change LPV, when 2026 taxes become due, and whether you need the Assessor, Treasurer, Recorder, State Board of Equalization or Tax Court next.

Get the quick answer Search assessment Check current deadlines
Arizona timing warning: a Notice of Value mailed in 2026 can establish the value for tax year 2027. Do not compare a 2027 Notice of Value directly with a 2026 tax bill without checking the tax year printed on each document.

Quick answer: start with the Maricopa County Assessor

Use the official Assessor search when you need an APN, owner listing, property characteristics, legal class, Full Cash Value or Limited Property Value. Search with one reliable identifier, open the correct parcel, verify the APN plus physical address, and then use the Treasurer only when you need the actual tax bill, balance, payment or receipt.

1 Find the parcel Search APN, full owner name or formatted address.
2 Verify the match Match APN plus physical property location.
3 Decode value Read FCV, LPV, legal class and assessment ratio separately.
4 Route the task Assessor for value; Treasurer for tax; Recorder for deeds.

Full address returned nothing Remove city, state, ZIP and street type. Keep number, direction and street name.
Owner search failed Use the full first name instead of an abbreviation and try a trust or legal entity name.
APN has dashes or letters The Assessor accepts multiple formats, so try the number without punctuation.
Recent purchase is missing Search the prior owner and confirm the deed through the Recorder.
New split or combination Search the parent APN; splits and consolidations can create new parcel numbers.
Vacant land has no normal address Use APN, owner information, subdivision/MCR clues or parcel-map context.

What to do if it looks wrong
Full Cash Value (FCV)
The Assessor’s market-oriented value unless another statutory valuation method applies.
Market data, property characteristics and applicable valuation rules.
Review comparable sales and appeal within the noticed-year deadline.
Limited Property Value (LPV)
The value normally used as the basis for primary and secondary property-tax calculations.

Check the calculation and triggering property changes; LPV itself is not ordinarily appealed as market value.
Legal Class
Arizona property-use classification.
Primary residence, rental, commercial, agricultural or other use.
Use legal-class correction or Notice of Claim when appropriate.
Assessment Ratio
Statutory percentage assigned to the property’s class.
Property class and tax year.

Assessed LPV
LPV multiplied by the applicable assessment ratio.
LPV and classification.
Check both inputs before disputing the Treasurer’s calculation.
Tax Area / jurisdictions
Combination of county, city, school and special taxing jurisdictions.
Boundary and taxing-district changes.
Compare the parcel’s tax-area information with the Treasurer statement.
Notice of Value ≠ property tax bill. The Assessor establishes property values and classifications. The Treasurer calculates, mails and collects the property tax statement.
Assessment ratio

For a typical primary residence, 10% is applied to LPV—not to your tax bill

Residential example

If a Class 3 primary residence has a Limited Property Value of $400,000, applying the 10% assessment ratio creates an assessed LPV of $40,000.

The Treasurer then applies the parcel’s applicable tax rates to assessed value. The homeowner does not simply owe 10% of $400,000.

Mixed-use warning: one parcel can involve more than one classification percentage. Do not apply the Class 3 residential ratio to the entire property when the official record shows mixed use.
Limited Property Value

Rule A and Rule B explain many surprising LPV changes

Rule A · Standard property

Most properties use Rule A. LPV generally increases by 5% from the prior year’s LPV, but it cannot exceed the current FCV.

OR
Rule B · Major statutory change

LPV is recalculated using the relationship between LPV and FCV for comparable property when a qualifying statutory trigger applies.

Events that can trigger Rule B

New construction or major improvements
Demolition or destruction
Property split or subdivision
Parcel consolidation or combination
Certain changes in property use
Property previously omitted from the tax roll
Certain special-valuation program changes
Other statutory events requiring LPV recalculation
Rule B does not automatically mean a tax increase. Maricopa County explains that a Rule B calculation can create a lower, higher or similar LPV depending on the property’s FCV and the applicable comparison ratio.
Read official LPV explanation
2027 market-value context

Countywide median FCV movement is mixed—not one universal increase

The Assessor reported different median Full Cash Value movements for 2027 notices. These countywide medians are useful context, but they do not prove that a specific parcel is correctly valued.

-1.9% Single-family residential median FCV
-3.5% Condominium median FCV
-8.9% Apartment median FCV
+4.1% Commercial median FCV
+5.2% Vacant-land median FCV
Manufactured housing

Published median 2027 FCV change: +2.7%.

Countywide real property

The Assessor reported more than $1.14 trillion in total FCV for tax year 2027.

How to use these numbers: compare your parcel’s percentage change with similar local properties and actual relevant sales—not only the countywide median for the property category.

2026 property tax calendar

2026 first-half property tax is due October 1

First half due October 1, 2026

2026 first installment due date.

First-half delinquency After November 1

Because November 1, 2026 is Sunday, the statutory next-business-day rule applies.

Second half due March 1, 2027

Second installment for tax year 2026.

First-half delinquency

Arizona law treats the first half as delinquent after November 1, subject to the next-business-day rule when the date falls on a weekend or legal holiday.

Second-half delinquency

Ordinarily after May 1, 2027; weekend/holiday rules can move the effective cutoff to the next business day.

$100-or-less rule

Arizona’s general property-tax guidance requires the full amount in one installment when total property tax is $100 or less.

Treasurer parcel-search quirk

The Treasurer formats APNs differently from the Assessor search. The Treasurer says to enter the first eight numbers of the parcel plus an alpha letter if one exists. The final ninth digit and dashes are not required. For mobile-home or business-personal-property accounts, the Treasurer uses the personal-property roll number with a leading 9.
Delinquent interest matters. The Treasurer states that delinquent property tax is subject to 16% simple interest under Arizona law and that interest accrues beginning with delinquency. Check the live parcel before sending a late payment.

Current valuation relief

September 1, 2026 is a critical relief deadline

Current action: as of August 20, 2026, eligible homeowners still have time to file Senior Valuation Protection by September 1. Certain late Personal Exemption applications also use September 1 when accompanied by an approved deadline waiver.

Senior Valuation Protection — “Senior Freeze”

Age

At least one household member must be age 65 or older.

Residency

The program requires qualifying primary-residence and residency conditions.

2026 income

$47,712 maximum for one owner or $59,640 for two or more owners, averaged over the prior three years.

Deadline

September 1, 2026. Approved participation lasts three years before renewal.

The Senior Freeze does not freeze the property-tax bill. It freezes qualifying Limited Property Value. Tax rates, special assessments and other tax components can still change.

Residential legal class

Primary residence and rental classification can affect the record even when both use 10%

A Class 3 primary residence and a Class 4 rental/non-primary residence can both use a 10% assessment ratio, but legal classification still matters for statutory treatment, owner-occupancy records and certain value calculations.

Primary residence

Check whether the Assessor record reflects owner occupancy and the correct Class 3 subclass.

Rental property

Arizona law requires residential rental registration. Maricopa’s Assessor customer portal is used to register rental property and correct applicable legal class.

FCV is unchanged but tax increased Review taxing-jurisdiction rates and levies on the Treasurer statement.

Maricopa tax assessment FAQs

How do I search a Maricopa County property assessment?

Use the official Maricopa County Assessor search. Search by APN, full owner name or formatted street address, open the matching parcel, and verify the APN plus physical location before using its FCV, LPV, legal class or property details.

Can I search Maricopa property by owner name?

Yes. The Assessor’s search guidance says to enter the owner’s name in full and not abbreviate the first name. If a property is held by a trust or business, also try the legal entity name.

What APN format does the Maricopa Assessor accept?

The Assessor accepts common APN formats with or without separators, including an alpha split suffix. Examples published by the county include formats such as 111-11-111-A, 11111111 and 11111111A.

What is the difference between FCV and LPV?

Full Cash Value is the Assessor’s market-oriented value unless another statutory method applies. Limited Property Value is the statutory value normally used in calculating property tax. LPV cannot exceed FCV.

What is the 2026 assessment ratio for a Maricopa primary residence?

A typical Class 3 primary residence uses a 10% assessment ratio. The ratio is applied to Limited Property Value to calculate assessed LPV; it is not a 10% property-tax rate.

When are 2026 Maricopa County property taxes due?

The first half of 2026 property tax is due October 1, 2026 and is delinquent after November 1, subject to Arizona’s next-business-day rule when that date falls on a weekend or legal holiday. The second half is due March 1, 2027 and ordinarily becomes delinquent after May 1.

Why did I receive a 2027 Notice of Value in 2026?

Arizona establishes real-property values in advance. Maricopa County mailed the 2027 Notice of Valuation on February 20, 2026, so always compare records using the tax or valuation year printed on the document.

Can I still appeal my 2027 Maricopa property value?

The regular County Assessor real-property appeal deadline for the 2027 notice was April 21, 2026 and that ordinary filing window has passed. A qualifying factual or legal-classification error may use the separate Notice of Claim process; judicial or later appeal rights depend on the specific procedural history and deadlines.

What is the 2026 Maricopa Senior Freeze deadline?

The Senior Valuation Protection application deadline is September 1, 2026. The program freezes qualifying Limited Property Value for three years, not the final property-tax bill, and applicants must meet age, residence and income requirements.

What is the difference between the Maricopa Assessor, Treasurer and Recorder?

The Assessor maintains parcels, property facts, FCV, LPV, classification and valuation-relief programs. The Treasurer handles tax bills, payments, balances and receipts. The Recorder maintains deeds, liens, plats and other recorded documents.

Information reviewed August 20, 2026: Maricopa Assessor search syntax, parcel counts, FCV and LPV guidance, Rule A and Rule B, 2027 Notice of Value dates, current appeal status, 2026 assessment ratios, Treasurer payment routing, statutory tax dates, Senior Valuation Protection, Personal Exemptions, residential legal-class changes, Recorder document-search behavior, office contacts and current 2026/2027 deadline information were checked against Maricopa County, Arizona Department of Revenue and Arizona statutory sources.

Verify with the official Ohio source

These calculators use the verified 2026 Ohio Department of Taxation amounts and statutory rules. For your exact bill, exemption status, and county-specific deadlines, always confirm with your county auditor and the Ohio Revised Code:

Ohio Dept. of Taxation — Real Property DTE Forms (105A, 105C, 1, 109) ORC 5715 — Board of Revision ORC 5713 — Taxable Real Property ORC 322.02 — Conveyance Fee ORC 319.54(F)(3) — State Fee ORC 5713.30 — CAUV tax.ohio.gov — Main Portal

Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties. Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
