Property Taxes in Surprise, AZ: How Your Bill Is Calculated and What to Watch For

How Arizona calculates the tax on a Surprise home, what the city charges, key dates, and two costly mistakes to avoid.

Property taxes in Surprise are lower than many people moving from California or the Midwest expect, but the bill works differently than in most states. This guide explains how Arizona calculates the tax on a home in Surprise, what the City of Surprise charges, the dates that matter, and the two mistakes that cost new owners money most often.

Quick answer: Your bill is based on your home's Limited Property Value, not its sale price. Arizona taxes a primary residence on 10% of that value, then applies the combined rates of every district your parcel sits in (Maricopa County, the City of Surprise, your school district, the community college district and others). To see the exact amount for any home, look up the parcel on the Maricopa County Treasurer's site.

Coming up: First-half 2026 taxes became due October 1 and are delinquent after 5 p.m. on Monday, November 2, 2026 (November 1 falls on a Sunday this year).

How property tax is calculated on a Surprise home

Arizona uses three numbers, and all of them appear on the Notice of Value the Maricopa County Assessor mails each year.

Step	What it means
Full Cash Value	The Assessor's estimate of market value.
Limited Property Value (LPV)	The value your tax is actually based on. It normally rises no more than 5% a year and can never be higher than Full Cash Value.
Assessed value	For a primary residence, 10% of the LPV. This is the number the tax rates are applied to.

Rates are quoted in dollars per $100 of assessed value. Your bill is the assessed value, divided by 100, times the combined rate for your tax area, minus any credits.

The 5% cap is why two identical houses on the same street can have different tax bills: one owner may have years of capped increases while a newer home's value was set more recently. A home's LPV can jump by more than 5% (the Assessor calls this "Rule B") when it is newly built, has a large addition, is split or combined with another parcel, or was left off the rolls by mistake. A normal sale by itself does not reset the LPV.

What the City of Surprise charges

The city's part of your bill is small compared to schools and the county. In June 2026 the Surprise City Council kept both city rates the same as the year before:

Primary rate: $0.5534 per $100 of assessed value (funds city services through the General Fund)
Secondary rate: $0.3880 per $100 of assessed value (repays voter-approved bonds)

For example, a home with an LPV of $350,000 (an illustrative number, not a typical value) has an assessed value of $35,000. The city's share would be about $193.69 primary plus $135.80 secondary, or roughly $329 a year. Everything else on the bill comes from the county, your school district, the community college district, fire and library districts and any special districts, and those rates vary by neighborhood, so always check the specific parcel.

Credits and programs that lower the bill

State Aid to Education (homeowner rebate): If the home is your primary residence and classified that way, the state automatically pays part of your school district's primary tax for you, up to $600 a year. It shows on the bill as a "State Aid to Education" line. No application is needed, but your classification has to be right (see below).
Senior Valuation Protection ("Senior Freeze"): Homeowners where at least one owner is 65 or older, who have lived in the home at least two years and whose income averages no more than $47,712 (one owner) or $59,640 (two or more owners) over three years can freeze the home's LPV for three years. It freezes the value, not the tax amount. Applications run January 1 to September 1 each year with the Maricopa County Assessor; 2027 applications open January 1, 2027. This is worth knowing in Surprise's 55+ communities such as Sun City Grand.

Two mistakes new owners make

1. Your home is not classified as your primary residence. A home you live in should be Legal Class 3.1 (primary residence). If it is listed as a non-primary or rental home, you lose the State Aid to Education credit. Check your classification on the Assessor's parcel page after you close. If it is wrong, file a Request for Residential Legal Class Change with proof such as an Arizona driver's license or voter registration showing the property address. A request filed and approved before July 1 applies to that tax year and the next; after July 1 it applies to the next year. Earlier years (up to three back) can be corrected with a Notice of Claim.

2. Budgeting a new build on its first tax bill. On a brand-new home, the first bill may reflect only the lot, or a home that was not 100% complete on the valuation date, and it may not show a primary-residence class yet. The full house value catches up on a later bill, often through a supplemental notice. If you are buying new construction in Surprise, plan for the full tax and ask your lender how your escrow account will handle the jump so your mortgage payment does not surprise you later.

Key dates

Date	What happens
Before March 1	Assessor mails Notices of Value for the next tax year; you have 60 days from the mail date to appeal the value.
September 1	Deadline for Senior Valuation Protection applications.
September	Tax bills are mailed by the County Treasurer.
October 1	First half of the year's taxes is due.
November 1, 5 p.m.	First half is delinquent (moves to the next business day if it falls on a weekend; November 2 in 2026).
December 31	Pay the full year by this date to avoid interest on the first half.
March 1	Second half is due.
May 1, 5 p.m.	Second half is delinquent.

If you have a mortgage with an escrow account, your lender usually pays these for you. Bills of $100 or less are due in full October 1 and delinquent after December 31.

Frequently asked questions

What is the property tax rate in Surprise, AZ?

The City of Surprise's own rates are $0.5534 (primary) and $0.3880 (secondary) per $100 of assessed value, kept unchanged in June 2026. Your total rate is higher because it also includes Maricopa County, your school district, the community college district and other districts, and it varies by neighborhood. Look up the parcel on the Maricopa County Treasurer's site for the exact amount.

How are property taxes calculated in Arizona?

For a primary residence, the tax is based on 10% of the home's Limited Property Value, which normally rises no more than 5% a year. That assessed value is divided by 100 and multiplied by the combined rates of the districts the home is in, minus credits such as State Aid to Education.

Do property taxes go up when you buy a home in Arizona?

Not just because of the sale. Arizona's Limited Property Value does not reset when a home sells, so a buyer generally inherits the seller's capped value. Taxes can still rise if district rates change, the value rises within the 5% cap, or the home was recently built or changed.

When are property taxes due in Maricopa County?

The first half is due October 1 and delinquent after 5 p.m. on November 1, and the second half is due March 1 and delinquent after 5 p.m. on May 1. If a delinquency date falls on a weekend or holiday, it moves to the next business day, so the first half of 2026 taxes is delinquent after 5 p.m. on November 2, 2026.

Is there a property tax break for seniors in Surprise?

Yes. Maricopa County's Senior Valuation Protection freezes the home's Limited Property Value for three years for eligible owners 65 and older who meet residency and income limits. Apply between January 1 and September 1.

Why is my first property tax bill on a new build so low?

The first bill may reflect only the lot or a partly finished home as of the valuation date. The full value of the finished home usually shows up on a later bill, so budget for the higher amount and confirm your classification as a primary residence.
