New to this? Quick definitions
- Effective tax rate —
- what you actually pay in property tax as a % of your home's value each year, after any local exemptions.
- Assessed value vs. market value —
- market value is what a buyer would pay; assessed value is the number your county uses to calculate your tax bill, which may lag market value.
- Mill rate —
- another way some counties express the tax rate — dollars owed per $1,000 of assessed value. It converts to the same effective rate.
- Homestead exemption —
- a discount some states offer on the assessed value of your primary residence, which lowers your tax bill. You usually have to apply for it.
- Escrow —
- after you close, an ongoing account your lender manages that collects a slice of your property tax (and insurance) with every mortgage payment, then pays the county for you.
- Reassessment —
- when the county updates your home's assessed value — often triggered by a sale, renovation, or a routine cycle — which can raise (or lower) your tax bill.

Mistakes first-time buyers make
- Assuming the seller's current tax bill is what you'll pay — reassessment at your purchase price often raises it.
- Not checking whether the county offers a homestead exemption, then forgetting to apply for it after closing.
- Missing the appeal deadline window — most counties only give you 30-90 days after your assessment notice arrives.
- Comparing homes across counties using the statewide average rate instead of each county's actual rate.
Pro tips
- Ask your agent for the exact county effective tax rate before you write an offer — not the statewide average.
- Calculate what your bill would be after reassessment at your actual purchase price, not the seller's old assessed value.
- Mark your calendar for the appeal deadline the day you get your first assessment notice — it's easy to miss.
- If Arizona offers a homestead exemption, apply for it right after closing — it usually isn't automatic.

Assessed value vs. market value
Some states assess at a fraction of market value. Arizona's effective rate of 0.52% is calculated on market value. If you paid $420,310, your starting assessed value is approximately that amount.
How to appeal
If your assessment is higher than comparable sales in your area, you can appeal. File with your county Board of Assessment Appeals within the deadline on your notice (typically 30-90 days). Bring 3-5 recent comparable sales ("comps") pulled from Zillow or your county recorder. The process is free.
What drives reassessment
Triggers include your purchase price being recorded at county, permitted renovation work, and periodic mass appraisals. New construction is always assessed on completion.
