Does Refinancing Affect Your Property Taxes in Arizona? 2026 Guide

No. Refinancing your mortgage in Arizona does not raise your property taxes. The appraisal your lender orders during a refinance never gets sent to the county assessor, and it plays no role in how your tax bill is calculated. This is easily one of the most common worries we hear from homeowners in Scottsdale and Phoenix, and the answer is genuinely reassuring.

Here is why, plus the handful of things that actually can move your payment after a refinance.

Why your refinance appraisal does not touch your tax bill

Two completely separate valuations exist on your home. Your lender hires a licensed appraiser to estimate market value so it knows how much it can safely lend. The Maricopa County Assessor separately assigns your home a Full Cash Value and a Limited Property Value using mass appraisal models and recorded sales data across your area.

Those two systems do not talk to each other. The assessor is not sitting there waiting for refinance appraisals to come in. Your taxes are calculated off the Limited Property Value, which is set by the county on its own schedule regardless of whether you refinance, sell, or do nothing at all.

Proposition 117 protects Arizona homeowners

Arizona voters passed Proposition 117 in 2012, and it amended the state constitution so that the Limited Property Value of a locally assessed property cannot rise more than 5% in a single year. That cap applies no matter how hot the market gets around you.

Arizona also does not reset valuation when a property changes hands. In some states a sale triggers a full reassessment at the new price. Here the LPV cap simply carries forward to the new owner. If a sale does not trigger a reassessment in Arizona, a refinance certainly does not.

What can change after you refinance

Your tax rate stays put, but a few things around it can shift, and this is where homeowners get confused.

Your escrow account gets rebuilt. Refinancing closes your old impound account and opens a new one. Your prior lender refunds the old balance, usually within 30 days, while the new lender collects a fresh cushion at closing. The tax amount did not change. The plumbing around it did.

You add or drop impounds. If you were paying taxes and insurance yourself and you choose an escrowed loan this time, your monthly payment jumps even though your loan amount and rate look great. Nothing went wrong. You are just prepaying bills you used to write checks for twice a year.

You do a cash out refinance and pull permits. This one is real. The refinance itself is invisible to the assessor, but if you use the cash for an addition, a casita, a pool, or anything that requires a permit, that permitted improvement can raise your Full Cash Value in a future assessment cycle. The renovation triggers it, not the loan.

Should Arizona property taxes factor into your refinance decision at all?

Only in the sense that you should know your real number before you shop. Arizona counties mail a Notice of Value in the late winter for a tax year almost two years out, so the figure your lender uses in a payment quote may be based on a bill that is about to change. Ask your loan officer which tax figure they used. It is a two minute question that prevents an unpleasant surprise at the first escrow analysis.

Beyond that, the property tax question should not stop anyone from refinancing. If you bought in the Valley when rates were near 7% and you have not looked at your options since, the tax side of the equation is not the thing standing in your way. We shop several wholesale lenders at pillarmortgagegroup.com and can tell you in one conversation whether the numbers work.

Frequently asked questions

Does a refinance appraisal get reported to the county in Arizona?

No. A refinance appraisal is a private report prepared for your lender. It is not filed with the Maricopa County Assessor or any other Arizona county assessor, and it has no effect on your assessed value or your tax bill.

Will a cash out refinance raise my property taxes?

Not by itself. Pulling equity out of your home does not change your assessed value. What can raise it later is a permitted improvement funded with that cash, such as an addition or a pool, because permitted work does get reported to the county.

Why did my payment go up after refinancing if my rate went down?

Almost always the escrow account. A new lender collects a fresh tax and insurance cushion, and if your county tax amount or homeowners insurance premium rose since your last escrow analysis, the monthly escrow portion rises with it. Your principal and interest can drop while the total payment holds steady or climbs.

How much can Arizona property taxes increase in a year?

Under Proposition 117, the Limited Property Value used to calculate your taxes cannot increase more than 5% per year. Your actual dollar bill can still move with tax rates set by school districts, cities, and other jurisdictions, but the valuation side is capped.
