Tax Attorney in Tempe, AZ
Federal IRS representation for Tempe residents, Arizona State University faculty and graduate students, Sun Devils NIL athletes, post-doctoral researchers, H-1B and L-1 visa-holders, and East Valley businesses — audits, back taxes, liens, levies, Offer in Compromise filings, FBAR Streamlined Filing, and U.S. Tax Court petitions at the Sandra Day O'Connor Courthouse in Phoenix. Tempe is the academic capital of Arizona: ASU's main campus, W.P. Carey School of Business, the Sandra Day O'Connor College of Law, the Walter Cronkite School of Journalism, the Ira A. Fulton Schools of Engineering, and one of the largest international-student populations in the country sit inside the city limits. Apollo Education Group (University of Phoenix), CarSales.com US headquarters, Desert Financial Credit Union headquarters, and a steady migration of Bay Area tech transplants overlay the same ZIPs. Federal IRS practice plus Arizona Department of Revenue work, handled together.

If you owe back taxes in Tempe, here is what changed in 2026
The IRS resumed full passport-revocation referrals under IRC §7345 for taxpayers with seriously delinquent federal balances above the inflation-adjusted threshold ($62,000 for 2026). For Tempe specifically, that hits four populations hard: ASU international students and post-doctoral researchers on F-1, J-1, and H-1B status whose entire U.S. immigration footprint depends on a valid home-country passport; Sun Devils athletes earning NIL income under IRC §61 who travel for Big 12 conference road games and bowl appearances; Bay Area tech transplants who relocated to ASU's research corridor and downtown Tempe and are now facing California Franchise Tax Board residency audits on equity that vested before the move; and Indian, Chinese, Korean, and Vietnamese H-1B engineers at Insight Enterprises, Wells Fargo Tempe, CarSales.com US, and State Farm regional whose offshore accounts were never reported on FinCEN Form 114 or Form 8938. The Arizona Department of Revenue has also tightened Transaction Privilege Tax enforcement on Tempe small businesses misclassifying TPT as a buyer's sales tax (the combined Tempe rate sits at 8.1% with state, county, and city layers — among the highest in Maricopa County). Acting before the levy, the passport certification, or the Notice of Proposed Assessment lands is materially easier than reversing it after the fact.

What this page covers and why Tempe-specific tax representation matters
Victory Tax Lawyers, LLP is a California-licensed tax-law firm whose primary practice is federal IRS resolution. We represent Tempe individuals, Arizona State University faculty and post-doctoral researchers, graduate students with F-1 OPT or STEM-OPT income, Sun Devils athletes with NIL contracts, H-1B and L-1 visa-holders, physicians, founders, 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.
Tempe 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 Tempe adds 1.8%, putting combined TPT in Tempe at 8.1% — higher than Chandler, Mesa, Gilbert, or Scottsdale. 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 — including ASU faculty with spouses still on nonresident-alien status under Treas. Reg. §301.7701(b).
Where Tempe diverges sharply from neighboring East Valley markets is the ASU overlay. Arizona State University's main Tempe campus enrolls one of the largest student bodies in the United States, joined the Big 12 Conference after leaving the Pac-12 in 2024, and houses the W.P. Carey School of Business, the Sandra Day O'Connor College of Law, the Walter Cronkite School of Journalism and Mass Communication, and the Ira A. Fulton Schools of Engineering — each generating distinct federal-tax issues. Faculty earn W-2 wages with retirement contributions to the Arizona State Retirement System; adjuncts get 1099 income subject to Schedule C and self-employment tax under IRC §1402; post-doctoral researchers receive stipends that may be qualified scholarships under IRC §117(c) or wages depending on services required; clergy at ASU-adjacent campus ministries get a parsonage allowance under IRC §107; Sun Devils football and basketball athletes earn NIL income that is ordinary self-employment income under IRC §61 with quarterly estimates under IRC §6654; research grant funds may be subject to IRC §174 R&E capitalization rules; and international students from India, China, South Korea, Vietnam, and across Asia face IRC §871 withholding, treaty-claim issues, and FBAR exposure on home-country accounts. Apollo Education Group (University of Phoenix headquarters), Desert Financial Credit Union headquarters, Insight Enterprises, CarSales.com US headquarters, Wells Fargo, State Farm regional, Charles Schwab, Honeywell Tempe, and adjacent Intel Ocotillo Chandler operations layer corporate W-2 and RSU exposure on top of the academic mix. 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 Tempe 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 on the ASU main campus, in downtown Tempe near Mill Avenue, in the Tempe Town Lake high-rises, in Warner Ranch, in South Tempe, or in the research-corridor housing along Rural Road. 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 Tempe 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. Tempe filings often turn on the asset-treatment question — ASU faculty with Arizona State Retirement System balances, post-doctoral fellows with deferred TIAA accounts, and Sun Devils athletes with NIL prepayments all sit awkwardly in RCP analysis. International students with home-country accounts in India, China, or Korea need careful Form 433-A treatment to avoid mischaracterizing FBAR-reportable funds as available equity. 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 Tempe real estate, brokerage accounts, and personal property. We pursue release after payment, certificate of discharge for specific property (often needed to close a sale in South Tempe, Warner Ranch, or the Tempe Town Lake high-rises), subordination to allow refinancing, and withdrawal under the Fresh Start lien-withdrawal program for IAs of $25,000 or less. For ASU faculty involved in classified DARPA-funded research at the Fulton Schools of Engineering, an NFTL on the public record can complicate the security-clearance 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 ASU W-2 paychecks, Apollo Education Group salaries, Insight Enterprises engineering wages, and 1099 contracts at Banner Health Tempe or Mountain Park Health 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. NIL-related audits on Sun Devils athletes and FBAR audits on ASU international students are an outsized share of Tempe exam activity.
Penalty abatement
First-Time Penalty Abatement administrative relief and Reasonable Cause requests under IRC §6651 and §6662. Common reasonable-cause arguments for Tempe filers include serious illness, broker-statement errors on RSU and ISO reporting, language-barrier and visa-status complications for F-1 and J-1 international students, NIL collectives that issued late or incorrect 1099s to Sun Devils athletes, and preparer reliance subject to the United States v. Boyle limits.
Twelve types of Tempe tax issues we handle
Federal IRS practice areas, with Tempe-specific framing where it matters.
ASU faculty W-2 plus 1099 overlap
Tenure-track and tenured ASU faculty earn W-2 wages with Arizona State Retirement System contributions, then layer 1099 income from textbook royalties, expert-witness work, summer consulting, and external course delivery. Schedule C reporting, IRC §1402 self-employment tax, and quarterly estimates under IRC §6654 all apply on the 1099 side. ASU adjuncts at W.P. Carey, the Cronkite School, and Sandra Day O'Connor Law adjuncts often face the same W-2-plus-1099 pattern with a smaller W-2 base.
Sun Devils NIL income
ASU joined the Big 12 in 2024, and Sun Devils football, basketball, baseball, and women's-program athletes earn NIL income through Sun Angel Collective and direct sponsorships. NIL payments are ordinary self-employment income under IRC §61 with SE tax under IRC §1402, quarterly estimates under IRC §6654, and 1099-NEC reporting from collectives. Athletes traveling to Big 12 road games in Texas, Kansas, West Virginia, and Florida pick up state nonresident-source obligations on appearance fees that the NCAA's pre-2021 rules never required them to track.
Post-doctoral fellow §117(c)
ASU post-docs at the Biodesign Institute, the School of Earth and Space Exploration, and the Fulton Schools of Engineering receive stipends that may qualify as scholarships excludable from gross income under IRC §117, or as taxable wages under §117(c) when the stipend requires services. The W-2 versus 1098-T versus no-form question depends on the grant terms. Many post-docs underreport because they treat the entire stipend as a tax-free scholarship when only the portion covering tuition and required fees qualifies.
ASU international student §871/§1441
ASU enrolls one of the largest international-student populations in the United States, drawing heavily from India, China, South Korea, Vietnam, Saudi Arabia, and Nigeria. F-1, J-1, and M-1 students are nonresident aliens for the first five calendar years under the substantial-presence test exemption. IRC §871 imposes 30% gross-basis withholding on most U.S.-source FDAP income absent a treaty claim on Form W-8BEN; IRC §1441 drives the withholding mechanics. Form 1040-NR and Form 8843 are required filings.
H-1B and L-1 FBAR / Form 8938
Tempe employs a large H-1B and L-1 visa population at Insight Enterprises, Wells Fargo Tempe back-office, CarSales.com US, Apollo Education Group, and adjacent Intel Ocotillo — recruiting from India, Taiwan, China, Korea, and Vietnam. Once a visa-holder becomes a U.S. tax resident under the Substantial Presence Test in Treas. Reg. §301.7701(b)-1, foreign accounts in the home country trigger FinCEN Form 114 (FBAR) at the $10,000 aggregate threshold and IRC §6038D Form 8938 at higher thresholds. The Streamlined Filing Compliance Procedures address non-willful prior-year gaps.
California departing-resident audits
Tempe became one of the post-2020 Arizona landing spots for Bay Area tech transplants drawn by the ASU research corridor and the downtown high-rise build-out. The California FTB pursues former residents under Cal. Rev. & Tax. Code §17041 and Publication 1031 for income sourced to California even after the Tempe move — vested equity, deferred comp, severance, RSU tranches earned during California service.
Apollo / University of Phoenix §174
Apollo Education Group, parent of the University of Phoenix, is headquartered in Tempe. For-profit-education subsidiaries face IRC §174 capitalization on internally-developed instructional-design software and course platforms under the TCJA amendments, with five-year domestic and fifteen-year foreign amortization producing unexpected federal income-tax liabilities. ASU's EdPlus operation faces parallel issues for its online-courseware development.
Clergy §107 parsonage
Tempe campus ministries at the All Saints Catholic Newman Center, the ASU LDS Institute, the Hillel Jewish Student Center, and other ASU-adjacent ministries pay clergy salaries. IRC §107 excludes the fair rental value of a parsonage or a designated housing allowance from gross income but not from self-employment income under §1402. The dual-status calculation is a recurring source of underpayment.
Intel Ocotillo RSU spillover
Intel Ocotillo sits just five miles south of Tempe in Chandler. Many Intel engineers live in Tempe and commute to Fab 12, Fab 42, Fab 52, and Fab 62. RSU vests on Form W-2 Box 12 V codes, ISO grants under IRC §422 with AMT exposure under IRC §55, and Tempe-resident filing on Arizona's 2.5% flat PIT all combine into the same April balance pattern.
Arizona TPT misclassification
Transaction Privilege Tax is a seller's tax, not a sales tax. Tempe contractors, Mill Avenue restaurants, ASU-adjacent retail, Tempe Marketplace tenants, short-term rental operators near Tempe Town Lake, and remote SaaS providers misclassify TPT obligations and end up with multi-year ADOR assessments. The combined Tempe rate is 5.6% state + 0.7% Maricopa + 1.8% city = 8.1% — one of the highest combined TPT rates in Maricopa County. We coordinate with the Arizona Department of Revenue under POA Form 285 on parallel federal exam matters.
Tempe Town Lake STR §280A
Short-term rentals near Tempe Town Lake, Mill Avenue, Tempe Marketplace, and Mountain America Stadium spike around ASU home football weekends, the Fiesta Bowl, Spring Training, and ASU graduation. Operators face IRC §280A dwelling-use limits on personal-use days, city TPT plus county transient-lodging exposure, and Schedule E or Schedule C reporting decisions that turn on services provided.
U.S. Tax Court petitions
Deficiency petitions filed in the Tax Court within 90 days of the Notice of Deficiency. Tempe 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 Tempe
1. NIL income with no estimates
A Sun Devils football or basketball athlete signs a Sun Angel Collective NIL deal mid-season, gets paid in tranches, and never files Form 1040-ES quarterly estimates under IRC §6654. The April balance plus underpayment penalty surprises them when the 1099-NEC arrives.
2. Post-doc treated stipend as scholarship
An ASU Biodesign post-doc treats the entire stipend as a §117 qualified scholarship when the grant terms required teaching or research services, making it taxable under §117(c). The IRS catches it via W-2 versus 1098-T cross-checks and assesses two-to-three years of back tax.
3. International student missed Form 8843
An ASU F-1 student from India or China filed Form 1040 instead of Form 1040-NR, missed Form 8843, claimed the standard deduction they were not entitled to, and skipped treaty paperwork on Form 8233. CP-series notices follow.
4. RSU vest withholding gap
Employer-default 22% supplemental withholding on a large Intel Ocotillo, Insight Enterprises, or Charles Schwab RSU vest understates the true marginal rate for a six-figure Tempe-resident engineer. The April balance hits as a surprise when the W-2 lands.
5. Unreported foreign account
An H-1B engineer or ASU faculty member arrives from India, Taiwan, China, or Korea and keeps the existing home-country account active without realizing that U.S. residency triggers FBAR and Form 8938 disclosure. The IRS picks it up via FATCA reporting from the foreign bank under the IGA and assesses penalties.
6. California exit illusion
A Bay Area engineer or ASU lateral-hire professor relocates to Tempe assuming the California tax bill is gone. The FTB issues a residency audit two years later claiming partial-year residency and California-source RSU income that vested before the move.
7. TPT classification failure
A Tempe Mill Avenue bar, a Tempe Marketplace retailer, a general contractor, or a remote SaaS seller invoices under the wrong TPT classification and ends up with a multi-year ADOR assessment plus penalties. At Tempe's 8.1% combined rate the dollar exposure on misclassified gross receipts is steep.
8. Startup payroll lapse
A Tempe research-corridor SaaS or biotech LLC stops depositing Form 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.
9. ERC clawback
Employee Retention Credit claims pushed by promoter mills are being clawed back through CP207/CP207L letters. Tempe Mill Avenue restaurants, downtown bars, dental practices, urgent-care groups, and small ASU-adjacent retail outfits face the audit wave.
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 Tempe research-corridor startups and Mill Avenue hospitality operators, this often catches the head of finance, controller, 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.
FBAR civil penalties
Under 31 USC §5321 and Bittner v. United States, 598 U.S. 85 (2023), non-willful FBAR penalties are assessed per-report rather than per-account. Willful penalties remain per-account and run at the greater of $100,000 (indexed) or 50% of the account balance. For Tempe ASU international students, post-docs, and H-1B filers, the Streamlined Filing Compliance Procedures generally reduce non-willful exposure to 0% (foreign offshore) or 5% (domestic offshore) of the high-balance amount.
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 Tempe move. The FTB pursues these as nonresident-source claims and can extend collection up to twenty years under Cal. Rev. & Tax. Code §19255.
NIL athlete multi-state nexus
A Sun Devils athlete who collects NIL appearance fees for events in Texas (no PIT), Kansas, Oklahoma, West Virginia, Florida (no PIT), Iowa State, and Cincinnati picks up nonresident-source income exposure in PIT states under each state's allocation rule. Federal Schedule C reporting consolidates the income; state returns multiply.
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 Form 1040 and the estate's Form 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. Cross-border estates involving Indian, Chinese, or Korean heirs add an additional layer of Form 706-NA and Form 3520 reporting.
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 Tempe post-doc, ASU lecturer, or research-corridor founder rebuilds runway after a fundraise gap or NIL-tax shock.
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, language and visa-status complications for F-1, J-1, H-1B, and L-1 filers, NIL collective reporting errors on 1099-NEC, and broker-statement reporting errors on RSU and ISO transactions.
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 — critical for visa-holders whose immigration status is tied to a valid passport.
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 Tempe 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 on the ASU main campus, in downtown Tempe near Mill Avenue, in Warner Ranch, in the South Tempe single-family submarket, or in the Tempe Town Lake high-rise corridor, 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 Tempe 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 Tempe attracts a meaningful share of Bay Area academic and tech transplants among its post-2020 inbound demographic. 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, and almost none combine that practice with the cross-border FBAR Streamlined Filing work the firm handles for ASU's international population.
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, Streamlined Filing, or Tax Court petition based on the financial profile and CSED runway.
Resolution filed
Forms 656, 433-A, 9423, 12153, FinCEN 114, Form 14653/14654 Streamlined certifications, 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, FBAR going-forward 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 (which matters significantly for ASU faculty on sabbatical abroad, post-docs on extended international research rotations, and visa-holders).
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 Tempe transplants from the Bay Area — the FTB has a 20-year statute of limitations on collection of California income tax under Cal. Rev. & Tax. Code §19255 after the assessment becomes final, 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.
Tempe venue: where federal and Arizona tax matters are heard
Federal tax matters affecting Tempe taxpayers proceed in federal venues, almost all of which sit in downtown Phoenix roughly 10 miles northwest. 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 Tempe 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 Tempe residents is at 4041 N Central Avenue, Phoenix AZ 85012, roughly 10 miles northwest via the 202 and 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. Tempe customer service routes through the Phoenix headquarters; businesses file through the centralized TPT licensing portal at AZTaxes.gov.
Maricopa County Assessor and Treasurer
The Maricopa County Assessor at 301 W Jefferson Street, Phoenix AZ 85003 assesses property value for Tempe parcels. The Maricopa County Treasurer at 301 W Jefferson Street, Suite 100, Phoenix AZ 85003 collects county property tax. Tempe, Chandler, Gilbert, Mesa, Scottsdale, 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 Tempe Tax & Finance
The City of Tempe Tax and Finance Office at 20 E 6th Street, 4th Floor, Tempe AZ 85281 administers the city portion of TPT (currently 1.8%) and city business licensing. Tempe is integrated with the centralized state TPT licensing system, so filings route through AZTaxes.gov rather than directly to the city. The combined Tempe TPT rate is 5.6% state + 0.7% Maricopa + 1.8% city = 8.1%.
Arizona Department of Economic Security
The Arizona Department of Economic Security administers state unemployment-insurance tax for Tempe employers. Federal payroll tax (FICA, FUTA, withholding) is enforced by the IRS separately. Tempe research-corridor startups, Mill Avenue restaurants and bars, dental practices, and ASU-adjacent service businesses often face dual DES-and-IRS payroll exposure simultaneously after a layoff event.
