Phoenix, AZ Tax Help: IRS & State Back Taxes, Levies, Audits (2026)
Tax help in Phoenix: who this guide is for
If you live or run a business in Phoenix and the IRS or ADOR has started writing to you, this page explains what actually happens next, where the local offices are and what they can and cannot do, and how cases from Maricopa County get resolved without anyone taking a day off to sit in a federal building.
I am an Enrolled Agent, federally licensed to represent taxpayers before the IRS, and my firm handles back taxes, levies, audits and unfiled returns for clients across Phoenix and its suburbs, including Mesa, Scottsdale, Chandler, Glendale, Tempe and Gilbert. Everything here is general information, not individual advice; the last section explains how to get a free review of your own notices.
Your IRS office in Phoenix, and what it can actually do
The IRS Taxpayer Assistance Center serving Phoenix is the IRS Taxpayer Assistance Center, Phoenix (Central), at 4041 North Central Ave., Phoenix, AZ 85012. By appointment only; call 844-545-5640. The IRS lists weekday service Monday through Friday, 8:30 a.m. to 4:30 p.m., and this office was open on all of the IRS's special Saturday dates in 2026; confirm in the IRS office locator. Other offices in the area include Glendale Taxpayer Assistance Center (named by the IRS; address not confirmed) and Mesa Taxpayer Assistance Center (named by the IRS; address not confirmed).
It helps to know what a Taxpayer Assistance Center is for. It can verify your identity, take a payment, give you transcripts and answer account questions. It does not negotiate: nobody at the counter can settle a balance, release a levy on their own authority or decide an audit. Those decisions sit with collection, examination and appeals units that work by mail, phone and fax, which is why most representation happens without a visit to the office at all.
The Taxpayer Advocate Service is different. It is an independent office inside the IRS that steps in when normal channels have stalled or a levy is causing hardship. The local office for Phoenix: Taxpayer Advocate Service, Phoenix office, 4041 N. Central Ave., MS-1005 PHX, Phoenix, AZ 85012, 602-636-9500. It is a genuine safety valve, but it is not a shortcut around filing the missing returns or answering the notice in front of you.
The Arizona side: Arizona Department of Revenue
Arizona has a personal income tax administered by the Department of Revenue, which also administers transaction privilege tax (TPT), Arizona's version of sales tax, for the state, counties and cities, including Phoenix. A Phoenix taxpayer can owe ADOR on two fronts at once: individual income tax and TPT for a business or rental.
Federal and state collection are separate tracks: an IRS installment agreement does nothing to stop a Arizona garnishment, and a state payment plan does not pause the IRS. Every Phoenix case we take is mapped across both agencies before anything is negotiated. Our Arizona state page covers the state side in detail.
Phoenix taxes people forget about
Beyond the IRS and ADOR, Phoenix has local obligations that show up as surprise bills, usually when a business or a rental has been running for a few years without them:
City of Phoenix transaction privilege (sales) tax: since January 1, 2017 the Arizona Department of Revenue has been the single point of administration and collection of state, county and municipal TPT, and a business engaged in taxable activity needs a TPT license to report its Phoenix TPT liability.
Residential rentals: under A.R.S. 42-6004(H), from and after December 31, 2024 no city or town may levy TPT on renting real property for residential purposes, but hotel, motel and other transient lodging businesses are excluded, so short-term rentals remain taxable.
Phoenix short-term rental permit: all STR properties must obtain a permit from the city's Planning and Development Department under the ordinance effective November 6, 2023, and an ADOR TPT license is part of the application.
Maricopa County business personal property: owners report each year the acquisition costs of active business assets to the County Assessor; the 2026 Business Property Statement deadline is April 1, 2026 under A.R.S. 42-15053(A).
Property tax: the Maricopa County Treasurer collects all real and personal property taxes for the county's tax districts, including cities, schools and special districts.
The Phoenix tax problems we see most
Every metro has its own pattern of tax trouble, because it has its own mix of work. In Phoenix the cases that reach us most often look like this:
Real estate agents and brokers: Commission income comes on 1099s with no withholding, so estimated payments are skipped in strong years and the balance surfaces at filing, when a slow market makes it hard to pay.
Short-term rental hosts in Scottsdale, Tempe and Phoenix: Transient lodging still carries TPT after the residential rental change, Phoenix requires a city permit, and the income must be reported federally; hosts who assumed the platform handled everything often have gaps with both ADOR and the IRS.
Snowbirds and part-year residents: Arizona presumes residency for anyone who spends more than nine months of the year in the state unless the stay was temporary, so retirees splitting time between states can have two states claiming the same pension income.
Construction and trades contractors: Cash-flow gaps between draws lead to missed payroll deposits and late Forms 941, and crews paid as contractors raise classification questions; unpaid employment tax is pursued against owners personally.
Restaurant and hospitality workers: Tips, second jobs and seasonal resort work produce multiple W-2s and unreported cash, and the IRS matching notices that follow must be answered on time with records.
Three things to know about Phoenix cases
One TPT license and return, administered by ADOR, covers state, Maricopa County and City of Phoenix privilege tax, so an ADOR TPT problem is automatically a Phoenix problem too.
Long-term residential rental TPT ended for periods after December 31, 2024 under A.R.S. 42-6004(H), while transient lodging stayed taxable, so landlords who shifted to short-term stays changed their tax status without changing property.
The Taxpayer Advocate Service and the IRS Taxpayer Assistance Center in Phoenix share the same address at 4041 N. Central Ave.
How we work with Phoenix clients
The process is the same whether you are in Mesa, Scottsdale and Chandler or overseas. You sign IRS Form 2848, which lets us speak to the IRS for you and pulls the notices to our office instead of your mailbox; for state matters we file the state's own power-of-attorney form. We then pull your IRS account and wage transcripts and the state account history, so the first conversation is about real numbers rather than guesses.
From there the order is almost always the same: stop any active levy or garnishment, file whatever returns are missing (a return the IRS prepared for you is usually far higher than the real liability), and only then negotiate the balance through a payment plan, an offer in compromise, penalty relief or currently-not-collectible status, depending on what the financials support. Meetings are by phone or video, documents move through a secure upload link, and signatures are electronic. You never need to visit an office, and neither the IRS nor ADOR requires an in-person meeting for the vast majority of cases.
Frequently Asked Questions
Do I need to go to the IRS office on North Central Avenue?
No. The Phoenix Taxpayer Assistance Center works by appointment through 844-545-5640, and collection cases and notices are handled by phone, mail and online. We work by phone, video and secure upload, and we file IRS Form 2848 so we can speak to the IRS for you.
Can you deal with the Arizona Department of Revenue and the IRS at the same time?
Yes. Arizona's income tax and TPT are separate from the IRS, so each agency needs its own authorization and its own plan. We handle them together so a payment arrangement with one does not leave the other unaddressed.
I rent a condo in Scottsdale on Airbnb. What am I supposed to be filing?
Federally, the rental income and expenses go on your return each year. In Arizona, short-term stays are transient lodging, which still carries TPT, and Phoenix requires a city STR permit inside city limits. We sort out which filings are missing before contacting either agency.
I spend winters in Mesa and summers up north. Which state do I owe?
It depends on domicile and days. Arizona law presumes a person who spends more than nine months of the year in the state is a resident unless the stay was temporary, and part-year and nonresident returns exist for split years. We review the calendars before anything is filed.
What does the Taxpayer Advocate in Phoenix do, and is that the same as hiring you?
The Taxpayer Advocate Service is an independent organization within the IRS that helps when IRS processes have failed or a taxpayer faces hardship. It does not represent you or prepare returns; when a case qualifies we prepare the Form 911 and work with the assigned advocate.
