Tax Attorney in Mesa, AZ
Federal IRS representation for Mesa individuals and businesses — audits, back taxes, liens, levies, Offer in Compromise filings, and U.S. Tax Court petitions at the Sandra Day O'Connor Courthouse in Phoenix. Mesa is the third-largest city in Arizona at roughly half a million residents, behind only Phoenix and Tucson. The economy here is its own thing: the Boeing Mesa plant builds the AH-64 Apache attack helicopter, Banner Gateway and Mayo Clinic Phoenix anchor the East Valley medical corridor, ASU Polytechnic sits on Williams Gateway, and the Mesa Arizona Temple has shaped the demographic mix for a hundred years. Federal IRS practice plus Arizona Department of Revenue work, handled together.

If you owe back taxes in Mesa, here is what changed in 2026
The IRS resumed full passport-revocation referrals under IRC §7345 for taxpayers with seriously delinquent federal balances over the inflation-adjusted threshold ($62,000 for 2026). Boeing Mesa employees with security-clearance review, Mayo Clinic Phoenix physicians on 1099 contracts, and Mesa retirees who winter in Mexico all face real exposure when a passport gets pulled. Three Mesa-specific 2026 pressure points sit on top of that: the California Franchise Tax Board continues to chase former California residents who relocated to East Valley cities like Mesa on stock-based comp that vested before the move, citing source-of-income rules under Cal. Rev. & Tax. Code §17041 and FTB Publication 1031; the Arizona Department of Revenue has tightened Transaction Privilege Tax enforcement on Mesa small businesses misclassifying TPT as a buyer's sales tax (the combined Mesa rate now sits around 8.3% with state, county, and city layers); and Defense Contract Audit Agency support of the Apache program at Boeing Mesa pulls clearance-eligibility reviews into the orbit of IRS collection status for cleared aerospace W-2 staff. Acting before the levy or the Notice of Proposed Assessment lands is materially easier than reversing it after the fact.

What this page covers and why Mesa-specific tax representation matters
Victory Tax Lawyers, LLP is a California-licensed tax-law firm whose primary practice is federal IRS resolution. We represent Mesa individuals, aerospace engineers, physicians, founders, snowbirds, clergy, and businesses before the Internal Revenue Service, the U.S. Tax Court, and the IRS Independent Office of Appeals through a Form 2848 Power of Attorney, which is recognized in every IRS district nationwide. Federal tax practice is not constrained by state-bar admission; under 31 CFR §10.3 (Circular 230), attorneys, CPAs, and enrolled agents may represent taxpayers before the IRS regardless of the taxpayer's state of residence.
Mesa tax practice has a specific shape. Arizona collects a 2.5% flat personal income tax under A.R.S. §43-1011 — the lowest flat PIT rate among states that impose a personal income tax. Corporate income tax is a flat 4.9% under A.R.S. §43-1111. The Transaction Privilege Tax structure is the structural surprise: TPT is imposed on the seller for the privilege of doing business in Arizona, not on the buyer at the register. The state rate is 5.6%, Maricopa County adds 0.7%, and the City of Mesa adds 2.0%, putting combined TPT in Mesa around 8.3%. Arizona is also a community-property state under A.R.S. §25-211, which changes federal income-tax analysis for spouses filing in or relocating to the state.
Where Mesa diverges sharply from other East Valley markets is the manufacturing-plus-medical-plus-religious overlay. Boeing's Mesa plant final-assembles the AH-64 Apache and AH-64E attack helicopter, supports Defense Department contracts under §174 capitalized R&E and security-clearance regimes, and generates a payroll mix of W-2 wages, RSU equity, and clearance-sensitive collection-status review. Mayo Clinic Phoenix — Mayo Clinic Hospital plus the Mayo Clinic College of Medicine and Science Phoenix — anchors much of Mayo's Arizona academic footprint in the East Valley, generating 1099 physician contracts, biotech RSU positions, and clinical-trial royalty streams that need careful Schedule E and Schedule C treatment. The Mesa Arizona Temple, one of the oldest temples of The Church of Jesus Christ of Latter-day Saints, anchors a deep concentration of religious-organization §501(c)(3) employment and §107 clergy housing allowances. If your problem is federal, you do not need an attorney admitted in Arizona. You need an attorney with active U.S. Tax Court bar membership and federal-practitioner credentials under Circular 230.
Your tax rights as a Mesa taxpayer
Federal taxpayer rights are codified across the Internal Revenue Code and summarized in IRS Publication 1, the Taxpayer Bill of Rights. They apply identically whether you live in Dobson Ranch, Mesa Grande, Las Sendas, Eastmark, Red Mountain Ranch, Augusta Ranch, or near the Falcon Field Airport corridor. The rights you can invoke in a tax-resolution matter:
Right to representation
Under IRC §7521(b)(2), an IRS examiner or collection officer must suspend an interview if you state you wish to consult with an authorized representative. A signed Form 2848 puts a tax attorney between you and the IRS for the remainder of the matter; the agency redirects all future correspondence through the CAF.
Right to Collection Due Process
After a Notice of Federal Tax Lien (IRC §6320) or a Final Notice of Intent to Levy (IRC §6330), you have 30 days to request a Collection Due Process hearing on Form 12153. CDP requests pause collection enforcement and preserve U.S. Tax Court review of any adverse Appeals determination.
Right to U.S. Tax Court review
A Notice of Deficiency triggers a 90-day petition window under IRC §6213(a). Filing a petition in Tax Court means you litigate without paying the deficiency first. Miss the 90 days and your only remedy becomes pay-then-sue in the U.S. District Court for the District of Arizona (Phoenix Division) or the U.S. Court of Federal Claims.
Right to an Offer in Compromise
Under IRC §7122, the IRS may accept less than the full liability where doubt as to collectibility, doubt as to liability, or effective tax administration justifies settlement. The offer is filed on Form 656 with Form 433-A(OIC) or 433-B(OIC) financial disclosure attached.
Right to a Collection Statute
IRC §6502 generally gives the IRS 10 years from the date of assessment to collect, after which the debt becomes uncollectible. Several events toll the period: pending OICs, bankruptcy, CDP hearings, and military deployment. Pull your IRS Account Transcripts to verify your Collection Statute Expiration Date before negotiating anything.
Arizona-specific: state taxpayer bill of rights
For matters at the Arizona Department of Revenue, the Arizona Taxpayer Bill of Rights under A.R.S. Title 42 grants taxpayers a written explanation of any assessment, the right to be represented by an attorney, CPA, or enrolled agent under POA Form 285, and the right to appeal through the State Board of Tax Appeals or the Maricopa County Superior Court Tax Court Division. The federal CSED and the state SOL run separately on parallel tracks.
How Victory Tax Lawyers helps Mesa taxpayers
Offer in Compromise
We prepare and file Form 656 with the supporting financials under IRC §7122. The IRS evaluates Reasonable Collection Potential (RCP) using your monthly income net of allowable expenses plus the realizable value of assets. Mesa filings often turn on the equity-stake question — vested RSU positions at Boeing Mesa and at Intel Ocotillo (the semiconductor spillover from Chandler) plus biotech RSU holdings tied to Mayo Clinic's Arizona research arm all sit awkwardly in RCP analysis. We pressure-test the math before submission so the offer survives at Appeals if intake rejects it.
Installment Agreement
Streamlined IAs (under $50,000), Non-Streamlined IAs over $50,000 with Form 433-F disclosure, and Partial Pay Installment Agreements under IRC §6159 that run only through the CSED. We pick the structure that fits the facts and the runway, not the structure the IRS Automated Collection System proposes by default.
Lien release and withdrawal
A Notice of Federal Tax Lien under IRC §6321 attaches to your Mesa real estate, brokerage accounts, and personal property. We pursue release after payment, certificate of discharge for specific property (often needed to close a Maricopa County home sale), subordination to allow refinancing, and withdrawal under the Fresh Start lien-withdrawal program for IAs of $25,000 or less. For Boeing Mesa employees holding active security clearance, an NFTL on the public record can complicate the SF-86 reinvestigation cycle; we move quickly on subordination and withdrawal in those matters.
Levy release
Wage levies (CP90 / LT11 series) and bank levies under IRC §6331 stop when we secure CNC status, an accepted IA, an accepted OIC, or a CDP request. Time matters: bank levies hold for 21 days before remittance under IRC §6332(c). Wage levies on Mayo Clinic 1099 contracts and Boeing W-2 paychecks need quick response or the next pay cycle disappears.
Audit and exam defense
Correspondence audits, office exams at the 4041 N Central Avenue IRS office in Phoenix, and field audits across the East Valley. We respond to Information Document Requests, attend the audit in your place under Form 2848, prepare the Form 4549 protest if we disagree, and take the case to the IRS Independent Office of Appeals if the examiner will not move.
Penalty abatement
First-Time Penalty Abatement administrative relief and Reasonable Cause requests under IRC §6651 and §6662. Common reasonable-cause arguments for Mesa filers include serious illness, broker-statement errors on RSU and ISO reporting, mission-service-related filing gaps for LDS clergy and missionaries, and preparer reliance subject to the United States v. Boyle limits.
Twelve types of Mesa tax issues we handle
Federal IRS practice areas, with Mesa-specific framing where it matters.
Boeing Mesa aerospace RSU and clearance
Apache helicopter program engineers at Boeing Mesa work under DOD contracts with §174 capitalized R&E exposure, RSU vests on Form W-2 Box 12 V codes, and SF-86 clearance reinvestigation cycles that pick up on IRS collection status. We coordinate the IRS resolution timeline against the clearance review calendar so a federal tax balance does not become a clearance problem.
Mayo Clinic Phoenix 1099 physician
Mayo Clinic Hospital and the Mayo Clinic College of Medicine and Science Phoenix anchor much of Mayo's Arizona footprint. Physicians on 1099 academic-medical contracts, biotech RSU positions from research partners, and clinical-trial royalty streams need careful Schedule E vs. Schedule C treatment plus IRC §1402 self-employment-tax analysis on the clinical income side.
California departing-resident audits
Arizona is the third-largest destination for residents leaving California, behind Texas and Nevada. The California FTB pursues former residents under Cal. Rev. & Tax. Code §17041 and Publication 1031 for income sourced to California even after the Mesa move — vested equity, deferred comp, severance, RSU tranches earned during California service. Mesa and Gilbert are common landing pads for the post-California tech and retiree mix.
LDS clergy and §501(c)(3) employment
The Mesa Arizona Temple anchors one of the highest concentrations of LDS households in the United States outside of Utah. Bishops, stake presidents, mission presidents, and full-time religious-organization employees navigate IRC §107 ministers' housing allowance, IRC §1402(e) SECA-exemption Form 4361 elections, and overlapping §501(c)(3) tax-exempt employment rules. Get the §107 designation in writing before year-end or the entire housing allowance gets recharacterized.
Arizona TPT misclassification
Transaction Privilege Tax is a seller's tax, not a sales tax. Mesa contractors, restaurants, remote sellers, and SaaS providers misclassify TPT obligations and end up with multi-year ADOR assessments. The combined Mesa rate is 5.6% state + 0.7% Maricopa + 2.0% city = 8.3%. We coordinate with the Arizona Department of Revenue under POA Form 285 on parallel federal exam matters.
Snowbird and dual-state residency
Mesa hosts one of the largest retiree and snowbird populations in the country — Mesa is essentially "Arizona" in the cultural shorthand of many Midwest and Pacific Northwest retirees. Winter visitors who spend more than half the year here may trigger Arizona residency under A.R.S. §43-104 while another state still claims them. Social Security taxation under IRC §86 and IRA RMDs under IRC §401(a)(9) add complexity.
Falcon Field aviation and Schedule C
Falcon Field Airport in northeast Mesa is one of the busiest general-aviation airports in the country, with major flight schools, CFI businesses, and aircraft-rental operations. Independent flight instructors and aircraft-leasing operators file Schedule C under IRC §162 and face hobby-loss exposure under IRC §183 if the aviation activity does not show profit motive across the nine-factor test.
Sky Harbor airline crew §40116
Phoenix Sky Harbor sits roughly 15 miles west of Mesa and is the duty base for many Mesa-resident pilots and flight attendants. Multi-state wage allocation for airline crew falls under 49 USC §40116, which limits the states that may tax airline pay to the crew member's state of residence and the state where more than 50% of scheduled flight time is performed.
Hispanic-American and ITIN filings
Mesa's proximity to the Mexico border and its large Hispanic-American population create a steady flow of Form W-7 ITIN applications, mixed-status household filings, FBAR exposure on Mexican bank accounts, and ITIN-renewal sequencing under IRC §6109. Streamlined Filing Compliance Procedures address prior-year FBAR gaps for non-willful filers.
Real-estate §1031 and STR §280A
Mesa was part of the post-2020 in-migration boom and home prices rose sharply. Many sellers missed the IRC §1031 identification deadline or misapplied the §121 primary-residence exclusion to an investment property. Mesa STR operators on Airbnb and Vrbo face IRC §280A dwelling-use limits, the seven-day average-rental trap, and city TPT plus county transient-lodging exposure.
Tribal-source and Salt River Pima
The Salt River Pima-Maricopa Indian Community sits directly adjacent to Mesa. Per-capita distributions to enrolled members are governed by IGRA and McClanahan v. Arizona State Tax Commission, 411 U.S. 164 (1973). Federal income-tax treatment turns on the source and use of the funds; reservation-source income may be exempt from Arizona state tax even when subject to federal tax.
U.S. Tax Court petitions
Deficiency petitions filed in the Tax Court within 90 days of the Notice of Deficiency. Mesa cases proceed to Phoenix trial sessions at the Sandra Day O'Connor U.S. Courthouse at 401 W Washington Street, Phoenix. Small-tax-case procedure under IRC §7463 applies to deficiencies of $50,000 or less per year.
Nine common causes of tax debt in Mesa
1. RSU vest withholding gap
Employer-default 22% supplemental withholding on a large Boeing or Intel-Ocotillo RSU vest understates the true marginal rate for a six-figure Mesa engineer. The April balance hits as a surprise when the W-2 lands.
2. ISO exercise plus AMT
An incentive stock option exercise creates an Alternative Minimum Tax preference under IRC §55. Many East Valley engineers exercise and hold, then watch the stock fall before sale and still owe AMT on phantom income.
3. California exit illusion
A tech worker or retiree moves to Mesa in 2024 assuming the California tax bill is gone. The FTB issues a residency audit in 2026 claiming partial-year residency and California-source RSU income that vested before the move.
4. Sold a Mesa home without §1031
Maricopa County saw aggressive 2020-2024 appreciation as the state ranked at the top nationally for net in-migration. Investment-property sales without a like-kind exchange under IRC §1031 triggered surprise capital-gains balances, and the §121 exclusion does not cover an investment property.
5. TPT classification failure
A Mesa general contractor invoices a project under the wrong TPT classification (prime contracting under A.R.S. §42-5075 vs. speculative builder) and ends up with a multi-year ADOR assessment plus penalties. The federal income-tax restatement often follows.
6. Startup payroll lapse
An East Valley SaaS or biotech LLC stops depositing 941 trust funds during a fundraise gap. The IRS asserts TFRP against the founders personally under IRC §6672. The state side becomes an Arizona Department of Economic Security unemployment-tax matter.
7. ERC clawback
Employee Retention Credit claims pushed by promoter mills are being clawed back through CP207/CP207L letters. Mesa restaurants, dental practices, urgent-care groups, and small construction outfits face the audit wave.
8. Clergy housing miscalculation
An LDS bishop or mission president treats the entire fair-rental-value of a parsonage as §107 housing allowance without a properly designated portion in writing from the religious organization in advance of the year. The IRS recharacterizes the excess and assesses tax plus penalties.
9. Snowbird-year residency mistake
A retiree spends seven months in Mesa, files as an Arizona nonresident, and receives an ADOR residency audit two years later. Federal Social Security taxation under IRC §86 and capital-gains recharacterization follow.
Who is on the hook: eight tax-liability scenarios
Joint filers in a community-property state
Arizona is a community-property state under A.R.S. §25-211. Joint federal returns create joint-and-several liability under IRC §6013(d)(3); even married-filing-separately requires federal community-property income allocation under Poe v. Seaborn principles. Innocent Spouse Relief under IRC §6015 is the principal escape valve.
Responsible persons for payroll
Trust Fund Recovery Penalty under IRC §6672 reaches anyone with check-signing authority who willfully failed to pay over withheld taxes — not just CEOs. For East Valley startups, this often catches the head of finance or office manager along with the founder.
Arizona TPT responsible party
Under A.R.S. §42-5028, the seller is personally liable for the Transaction Privilege Tax owed to the state on Arizona business activity. Officers and members with control of disbursements can be assessed individually when an entity fails to remit.
DOD contractor and clearance
Boeing Mesa Apache program staff hold active security clearance. SF-86 reinvestigation cycles touch financial responsibility issues per Security Executive Agent Directive 4 (Adjudicative Guidelines, Guideline F). An open IRS balance, NFTL, or active levy can become a clearance-eligibility concern. We sequence the resolution timeline against the reinvestigation calendar.
California source-of-income claims
Under Cal. Rev. & Tax. Code §17041 and the FTB's Publication 1031 sourcing rules, equity that vested while the taxpayer rendered services in California remains California-source on sale — even years after the Mesa move. The FTB pursues these as nonresident-source claims.
Nominee and alter-ego
The IRS files a nominee or alter-ego lien when assets titled in another's name actually belong to the taxpayer. Common in East Valley asset-protection structures using series LLCs, family-limited partnerships, and Arizona Asset Protection Trusts.
Arizona income-tax assessment
Arizona imposes a 2.5% flat PIT under A.R.S. §43-1011 and a 4.9% flat CIT under A.R.S. §43-1111. Underpayment carries interest and penalty exposure on the state side parallel to the federal balance. ADOR collection extends through the State Board of Tax Appeals and Maricopa County Superior Court Tax Court Division.
Estate and decedent returns
A decedent's final 1040 and the estate's 1041 are the executor's responsibility. Personal liability for the executor attaches under 31 USC §3713(b) if estate distributions are made before federal tax claims are satisfied. The Mesa retiree demographic generates a steady volume of these final-return matters.
What resolution can look like
Debt reduced
An accepted Offer in Compromise settles the federal liability for less than the full amount. Partial Pay IAs cap the recovery at what you can pay through the CSED. Currently Not Collectible status freezes collection while a Mesa physician on a 1099 contract rebuilds runway.
Penalties abated
First-Time Penalty Abatement removes failure-to-file and failure-to-pay penalties for a clean compliance year. Reasonable-cause requests address serious illness, mission-service filing gaps for LDS clergy, and broker-statement reporting errors.
Liens and levies released
An NFTL withdraws once a streamlined IA is in place under Fresh Start. Wage and bank levies release when the underlying account moves to CNC, IA, or OIC processing. Passport certifications reverse once the debt drops below the §7345 threshold.
Outcomes vary. Past results do not guarantee future outcomes. Each tax case is unique.
Settlement ranges from the firm's case files
The following ranges come from Victory Tax Lawyers cases over the past several years and contribute to the firm's $100M+ aggregate tax-relief figure. Names and identifying facts are removed for confidentiality.
| Matter type | Original liability | Resolution | Approximate result |
|---|---|---|---|
| Installment Agreement | $138,296 | IRC §6159 streamlined IA | $25/month accepted |
| Partial Pay IA | $126,489 | IRC §6159 PPIA through CSED | $50/month accepted |
| Installment Agreement | $128,206 | IRC §6159 streamlined IA | $25/month accepted |
| Partial Pay IA | $116,451 | IRC §6159 PPIA through CSED | $50/month accepted |
| Installment Agreement | $152,296 | IRC §6159 streamlined IA | $25/month accepted |
Past results do not guarantee future outcomes. Each tax case is unique and turns on facts, asset position, monthly disposable income, IRS Allowable Living Expense tables, and the discretion of the assigned Revenue Officer or Settlement Officer. Acceptance rates for Offer in Compromise vary widely — the IRS reported a nationwide acceptance rate of roughly 30 to 40 percent in recent years.
Why a California-licensed firm represents Mesa taxpayers
Federal tax practice is regulated by Treasury under 31 CFR Part 10 (Circular 230). An attorney admitted in any U.S. jurisdiction may represent any taxpayer before the IRS in any state via Form 2848 Power of Attorney. State-bar admission is a state-court question; the IRS is a federal agency, the U.S. Tax Court is a federal court of national jurisdiction, and the IRS Independent Office of Appeals is a federal administrative venue. Whether you live in Mesa proper, Eastmark, Las Sendas, Red Mountain Ranch, Augusta Ranch, or out near Falcon Field, the federal procedural rules are identical.
Parham Khorsandi is a member of the State Bar of California (license #266658) and is admitted to practice before the United States Tax Court — admission there is national, not state-bound. Amir Boroumand (Cal Bar #269570) supplements the firm's federal practice. For Mesa specifically, the California-bar credential is more than a procedural footnote: the FTB's departing-resident audit program reaches former California residents who relocated to Arizona, and we appear before the FTB on these matters regularly. Few Arizona firms see Cal. Rev. & Tax. Code §17041 source-of-income disputes at any volume.
For matters that require an attorney admitted in Arizona — for example, a contested Arizona Department of Revenue assessment that proceeds to the State Board of Tax Appeals and then to judicial review in the Maricopa County Superior Court Tax Court Division, or a litigated TPT classification dispute — we coordinate with local Arizona counsel and stay engaged on the federal side. The 100% remote workflow runs through a secure portal: document upload, signed Forms 2848 and 8821, AZ POA Form 285 where state matters require it, and weekly status updates without anyone needing to drive to downtown Phoenix.
The seven steps of a VTL tax-resolution engagement
Free consultation
A 30-minute call with an attorney to outline the facts, the IRS or ADOR notices received, and the realistic resolution options.
Engagement letter
A written attorney-client agreement defines scope, fee, and authority. Federal common-law attorney-client privilege attaches from signature forward.
Form 2848 filed
Power of Attorney filed with the IRS Centralized Authorization File so all subsequent IRS notices route to the firm. AZ Form 285 filed where state matters overlap.
CAF investigation
Account Transcripts, Wage and Income Transcripts, and Record of Account pulled across all open years. CSED dates verified before any negotiation.
Strategy memo
A written analysis recommending OIC, IA, CNC, audit response, CDP, or Tax Court petition based on the financial profile and CSED runway.
Resolution filed
Forms 656, 433-A, 9423, 12153, or Tax Court Petition prepared and filed. Negotiations with Revenue Officers, Settlement Officers, or Appeals Officers handled directly.
Compliance close-out
Post-resolution monitoring: future quarterly estimates, return filings, and protection against IA default. The case is done when the new pattern is stable.
Collection statute warning — federal, Arizona, and California
Under IRC §6502(a), the IRS generally has ten years from the date of assessment to collect a tax. After the Collection Statute Expiration Date, the debt becomes uncollectible by operation of law. Several events toll the CSED, including a pending Offer in Compromise (extends by the OIC pendency plus 30 days), bankruptcy filing (extends by the bankruptcy stay plus six months), a Collection Due Process hearing (extends while pending), Innocent Spouse claims, and continuous absence from the United States for six months or more.
On the Arizona side, the Arizona Department of Revenue generally has a four-year statute of limitations on assessment of state income tax under A.R.S. §42-1104, with longer periods for substantial omissions, fraud, or unfiled returns. Arizona's collection period after assessment under Title 42 runs on a separate track from the federal ten-year clock, and ADOR may renew judgments to extend collection.
On the California side — the third leg that matters for Mesa transplants — the FTB has a 20-year statute of limitations on collection of California income tax under Cal. Gov. Code §7172 after entry of the assessment, and a four-year statute of limitations on assessment under Cal. Rev. & Tax. Code §19057 (extended to six years for substantial omissions and unlimited for unfiled returns). The FTB collection horizon is twice the federal one. Pull every account transcript before negotiating anything; sometimes a Partial Pay Installment Agreement that runs out the federal statute is the better strategy than an offer that extends it.
Mesa venue: where federal and Arizona tax matters are heard
Federal tax matters affecting Mesa taxpayers proceed in federal venues, almost all of which sit in downtown Phoenix roughly 20 miles west. State matters that reach formal contest proceed through the Arizona Department of Revenue, the State Board of Tax Appeals or the Office of Administrative Hearings, and on judicial review through the Maricopa County Superior Court Tax Court Division.
U.S. Tax Court — Phoenix trial sessions
The United States Tax Court hears Mesa cases at the Sandra Day O'Connor U.S. Courthouse, 401 W Washington Street, Phoenix AZ 85003. Trial sessions are scheduled on rotation throughout the year; petitioners designate Phoenix as the place of trial under Tax Court Rule 140.
U.S. District Court — District of Arizona, Phoenix Division
The U.S. District Court for the District of Arizona, Phoenix Division sits at the Sandra Day O'Connor U.S. Courthouse, 401 W Washington Street, Phoenix AZ 85003. Federal refund suits under IRC §7422 and criminal-tax matters proceed there.
IRS Taxpayer Assistance Center — Phoenix
The nearest IRS TAC for Mesa residents is at 4041 N Central Avenue, Phoenix AZ 85012, roughly 20 minutes west on the 202 or I-10. Appointments are scheduled through the IRS office locator or 844-545-5640.
Arizona Department of Revenue — HQ
The Arizona Department of Revenue is headquartered at 1600 W Monroe Street, Phoenix AZ 85007. ADOR administers state PIT under A.R.S. Title 43, the Transaction Privilege Tax under A.R.S. Title 42 Chapter 5, withholding, and luxury tax. Mesa businesses file through the centralized TPT licensing portal under ADOR.
Maricopa County Assessor and Treasurer
The Maricopa County Assessor at 301 W Jefferson Street, Phoenix AZ 85003 assesses property value for Mesa parcels. The Maricopa County Treasurer at 301 W Jefferson Street, Phoenix AZ 85003 collects county property tax. Mesa, Gilbert, Chandler, Tempe, and Queen Creek all sit in Maricopa County.
Arizona Office of Administrative Hearings
The Arizona Office of Administrative Hearings at 1740 W Adams Street Suite 3000, Phoenix AZ 85007 hears state-tax cases referred by ADOR. The Arizona State Board of Tax Appeals reviews redetermination matters under A.R.S. Title 42 Chapter 5. Further appeal goes to the Maricopa County Superior Court Tax Court Division.
City of Mesa Tax & Revenue
The City of Mesa Tax & Revenue Office at 20 E Main Street, Suite 250, Mesa AZ 85211 administers the city portion of TPT (currently 2.0%) and city business licensing. Mesa is integrated with the centralized state TPT licensing system, so filings route through AZTaxes.gov rather than directly to the city. The combined Mesa TPT rate is 5.6% state + 0.7% Maricopa + 2.0% city = 8.3%.
Arizona Department of Economic Security
The Arizona Department of Economic Security administers state unemployment-insurance tax for Mesa employers. Federal payroll tax (FICA, FUTA, withholding) is enforced by the IRS separately. Mesa healthcare practices, SaaS startups, and Falcon Field aviation businesses often face dual DES-and-IRS payroll exposure simultaneously after a layoff event.
Request a free consultation with a Mesa-focused tax attorney
A 30-minute call with an attorney costs nothing. Bring your most recent IRS notice, your last filed return, any Arizona Department of Revenue correspondence, and any California FTB notice if you relocated from California.
