Cash Out Refinance Taxes in Arizona 2026: Is the Money Taxable and Is the Interest Deductible?

This comes up on almost every cash out call I take. Somebody is about to pull $120,000 out of a Scottsdale house and the thing keeping them up at night is whether the IRS is going to want a piece of it in April. Short version: no. The longer version is about the deduction, and that part is worth ten minutes of your attention because it changes the real cost of the loan.

Why the cash itself is not taxed

Borrowed money is not income. That is the whole principle. When you take $120,000 out of your home, you did not earn $120,000, you now owe $120,000 plus interest. The IRS treats a refinance as a continuation of the same mortgage debt rather than a sale or a gain, so there is nothing to report and no 1099 coming.

Selling is different. Sell the house and you are into capital gains, where the primary residence exclusion of $250,000 single and $500,000 married filing jointly does the heavy lifting. Refinance and none of that turns on, because no gain was realized. You still own it.

This holds regardless of what you do with the money. Pay off cards, buy a rental, take a trip. The proceeds are still not income. What you spent it on only matters for the deduction, which is the next section.

When the interest is deductible

Interest on the cash out portion is deductible only if you spent the money to buy, build, or substantially improve the home that secures the loan. That is the test, stated in IRS Publication 936, and it has been the rule since the 2017 tax law removed the general home equity interest deduction.

Read that sentence again, because two words carry all the weight. Substantially improve, and that secures the loan.

Substantially improve means capital improvement, not maintenance. A new kitchen, an addition, a pool, a casita, replacing the HVAC system, a roof. Repainting the bedroom and fixing a leaking valve are repairs, and repairs do not count. The line is not always obvious and this is exactly where a CPA earns their fee.

That secures the loan means the money has to go into the same property. If you cash out of your Scottsdale primary residence and use the money to renovate a rental in Mesa, the interest on that portion is not deductible as home mortgage interest, though it may be deductible somewhere else on your return as an investment expense. Different rules, different form, get advice.

The nuance that gets missed: your original balance keeps its own treatment. Owe $400,000 of acquisition debt, cash out another $100,000 for a boat, and the interest on the $400,000 is still deductible. Only the $100,000 slice is not. Publication 936 has the worksheet that allocates the balance across those categories.

The $750,000 cap, explained plainly

Deductible acquisition debt is capped at $750,000 for a married couple filing jointly, or $375,000 filing separately, on loans taken out after December 15, 2017. Debt from before that date is generally grandfathered at the older $1 million limit. Interest on balance above your applicable cap is simply not deductible, even when the money went into the house.

In most of Metro Phoenix this ceiling never comes up. In Paradise Valley, north Scottsdale, and Arcadia it comes up constantly, and it is a real factor in whether a jumbo refinance pencils the way an owner assumes it will.

Second point most people miss: the deduction only helps if you itemize. With the standard deduction where it sits, plenty of Arizona homeowners with a mid six figure balance take the standard deduction and get no benefit from mortgage interest at all. Running the numbers before you decide the tax treatment justifies the loan is not optional, it is the whole analysis.

Estimate your new payment

What to keep, and for how long

If you intend to deduct the interest on the cash out portion, you have to be able to prove where the money went. The burden is on you, not on the lender and not on the title company.

1. The closing disclosure from the refinance. Shows the loan amount and the cash to borrower figure.
2. Contractor invoices and paid receipts for the improvement work, with dates that come after the refinance closed.
3. Bank statements tracing the proceeds from deposit to payment. Do not commingle the money with a general savings account if you can avoid it. A dedicated account for six months makes this trivial.
4. Permits where the city pulled one. In Phoenix and Scottsdale a permitted addition creates its own clean paper trail.

Keep it as long as you own the home and a few years past the sale, because improvement records also raise your cost basis and cut your capital gain later. Same file, two jobs.

What this means for Arizona homeowners

Arizona does not add a separate tax on refinance proceeds, and the state generally starts from your federal figures for individual income tax, with the Arizona Department of Revenue publishing the annual conformity rules. There is no state level surprise waiting for you here. What there is, is a lot of equity. Values across the Valley climbed hard through the early part of this decade, which is why cash out volume in Arizona has stayed steady even with rates in the sixes.

The practical read: if the plan is a renovation, the tax treatment usually works in your favor, and the interest cost is lower than almost anything else you could borrow with. If the plan is paying off credit cards, the interest is not deductible, and that is fine, because trading a 24 percent card for a rate in the sixes is still a strong trade on its own merits. Just do not let anyone sell you the debt consolidation on a tax benefit that does not exist. We laid out that math in our guide to a debt consolidation refinance in Arizona, and the mechanics of the loan itself are covered in how to tap your home equity in Arizona.

If the property is a rental rather than your residence, the analysis changes again, and it is usually more favorable because interest on an investment property is a business expense. Our walkthrough of refinancing a rental property held in an LLC covers what lenders require on that side.

If you would rather just get numbers, tell us the scenario.

Honest caveat: I am a mortgage broker, not a CPA, and this is general information rather than tax advice for your return. If the deduction is a meaningful part of why you are doing the loan, get your accountant on the phone before you lock, not in April. And a cash out refinance is wrong for some people no matter how the taxes land. If you are sitting on a 3.25 percent first mortgage and you need $40,000, replacing the whole loan at today's rates to get it is usually a bad trade. A second mortgage or a HELOC keeps the low first in place, and we will tell you that even though it is the smaller loan for us.

Frequently asked questions

Is cash out refinance money taxable in Arizona?

No. Cash out refinance proceeds are borrowed funds, not income, so they are not taxable at the federal level and Arizona does not tax them either. You will not receive a 1099 for the money and nothing goes on your return.

Can I deduct the interest on a cash out refinance?

Only on the portion you used to buy, build, or substantially improve the home that secures the loan, and only up to the acquisition debt cap. Interest on the rest of the cash out amount is not deductible as home mortgage interest. IRS Publication 936 has the worksheet that allocates the balance.

Does paying off credit cards with a cash out refinance make the interest deductible?

No. Using the proceeds to pay off consumer debt is not a qualifying use, so that slice of interest is not deductible. The trade can still make sense financially, because a mortgage rate is far below a typical credit card rate, but it should not be sold to you as a tax benefit.

What is the $750,000 mortgage interest limit?

Deductible acquisition debt is capped at $750,000 for married filing jointly, or $375,000 filing separately, on loans taken out after December 15, 2017. Older debt is generally grandfathered at the previous $1 million limit. Interest on any balance above your cap is not deductible.

Do I need to itemize to benefit from the mortgage interest deduction?

Yes. The deduction only helps if your itemized deductions exceed the standard deduction. Many Arizona homeowners with moderate loan balances take the standard deduction and get no benefit from mortgage interest at all, so run that math before you count on it.
