Arizona Property Tax Rate: Maricopa County vs. Pima County (Tucson vs. Phoenix) Comparison
Pima County (Tucson) property tax rates run roughly 0.80–0.85% of assessed value, while Maricopa County (Phoenix) typically lands closer to 0.40% — meaning an identical home can cost noticeably more per month to own simply because of which county line it sits on.
If you're comparing Tucson and Phoenix as your next Arizona home base, this is one root worth digging into before you fall in love with a floor plan.
Two Counties, Two Very Different Tax Soils
Property taxes aren't set statewide in Arizona — they grow out of local soil. Each county, school district, and special taxing district plants its own rate, and those rates add up differently depending on where you're standing. Pima County, home to Tucson, generally carries a heavier effective tax burden than Maricopa County, home to Phoenix and its sprawling suburbs.
Why the difference? Population size, school funding structures, and the number of overlapping special districts (fire, library, flood control) all play a part. Maricopa's larger tax base spreads costs across more properties, often resulting in a lighter per-home load. Pima County, with a smaller base and different district layering, tends to need a higher rate to fund the same services.
What This Looks Like in Real Dollars
Let's plant a simple example. Say you're eyeing a $400,000 home in either metro.
- In Maricopa County (~0.40% effective rate), you might see roughly $1,300–$1,400 a year in property taxes — around $110–$115 folded into your monthly escrow payment.
- In Pima County (~0.80–0.85% effective rate), that same $400,000 home could carry closer to $3,200–$3,400 a year — nearly $270–$285 a month in escrow.
That's a difference of over $150 a month, or roughly $1,800+ a year, for a home that looks identical on paper. Multiply that over a 30-year loan term, and you're looking at a meaningfully different total cost of ownership — even though the sale price never changed.
Why This Sneaks Up on Buyers
Most home shoppers focus on the sale price and the monthly principal-and-interest number. But your full monthly housing payment is really a garden with several plants growing in it: principal, interest, taxes, and insurance. Property taxes are often the one buyers forget to water — until the escrow analysis shows up a year later with a surprise increase.
This is especially important for anyone relocating between Arizona metros or comparing Arizona to other states in our footprint. A home that seems "$50,000 cheaper" in one county might come with a tax load that closes some of that gap over time.
Planting Roots the Smart Way
If you're relocating to Arizona and weighing Tucson against Phoenix — or comparing either against other states — it helps to look at the whole map, not just the sticker price. Our Arizona state page walks through more local factors that shape ongoing homeownership costs, so you can compare apples to apples (or saguaros to palm trees) before you commit to a neighborhood.
It's also worth remembering that assessed value isn't always the same as market value, and both counties reassess on their own timelines. A seed planted today may grow into a different tax bill in a few years, so it's worth asking a local expert how recently a specific property was reassessed.
