Phoenix has hundreds of CPA firms. The challenge is not finding one — it is finding the right one for your situation, whether that means a growing business that needs bookkeeping, payroll and tax planning in one place, a household facing an IRS collection notice, or a medical practice that needs an accountant who already knows the industry.
We compared 10 firms on the criteria below, organised by specialty. Larry B. Betts, CPA takes the top spot with a 4.9 across 174 Google reviews and a small-business practice running since 2006. K&R Strategic Partners ranks third for owners who need tax, books, payroll and estate planning from one team — serving Phoenix from its Mesa office, about 20 to 35 minutes east.
Key Takeaways
- Larry B. Betts, CPA ranks first on 4.9 / 5 across 174 Google reviews.
- Rating alone is a weak signal. A 5.0 on 20 reviews is not stronger evidence than a 4.9 on 400; review depth is weighted here.
- Credentials decide who can represent you. Only CPAs, Enrolled Agents and attorneys can represent you before the IRS.
- Every rating below was checked as of July 2026 and should be re-verified before you engage a firm.
How We Ranked These Firms
- Credentials on staff — CPAs, Enrolled Agents, attorneys, and who can represent you before the IRS.
- Google rating weighted by review volume — a 5.0 on 21 reviews does not outrank a 4.9 on 174.
- Service breadth — tax preparation, accounting, payroll, consulting, entity formation, estate planning.
- Demonstrated specialisation — a clear niche or practice area, not just a claim of doing everything.
- Verifiable track record — years in business, named principals, and published service details.
The 10 best CPA firms in Phoenix
1. Larry B. Betts, CPA
Best for small business tax and accounting
Rating: 4.9 / 5 (174 Google reviews, as of July 2026)
Location: Phoenix (85020) — Credentials: CPA
Best for: Small business tax, accounting and planning
Website: phxcpa.com
Larry B. Betts CPA operates from 7330 N 16th Street in North Phoenix and has served small businesses and individuals since 2006. Services cover tax preparation, bookkeeping, tax planning, business consulting, payroll and wealth management — including S-Corp conversion guidance for owners looking to restructure.
4.9 across 174 Google reviews — the strongest combination of score and volume among Phoenix CPA firms on this list, built from nearly two decades of direct client work in the same location. The firm offers a 15% discount for military and first responders.
Betts earns the top spot because both the numbers and the service breadth hold up. If you need a CPA who handles the full scope of small business finances — not just the return — this is where to start.
2. The CPA Attorney
Best when you need a CPA and an attorney
Rating: 5.0 / 5 (116 Google reviews, as of July 2026)
Location: Phoenix (Biltmore / 85016) — Credentials: CPA + JD (Attorney)
Best for: Tax disputes and business litigation
Website: thecpaattorney.com
Todd Lenczycki is The CPA Attorney, practising from 2525 E Camelback Road in the Biltmore corridor. The distinguishing feature is a genuine dual credential: Lenczycki holds a CPA license and a Juris Doctorate from the Sandra Day O'Connor College of Law at ASU, with a B.S. in Accountancy from the W.P. Carey School of Business.
Practice areas reflect that combination — partnership disputes, contract disputes, opportunity zones, litigation support and business formation. This is built for situations where accounting and legal strategy intersect, particularly securities-fraud litigation.
5.0 across 116 Google reviews. The right call when your situation has a legal dimension — a fraud allegation, a partnership dissolution, or a transaction needing both a CPA's numbers and an attorney's structure. Not the pick for routine annual filing.
3. K&R Strategic Partners
Best full-service firm for business owners
Rating: 4.9 / 5 (88 Google reviews, as of July 2026)
Location: Mesa (serves Phoenix) — Credentials: CPAs + Enrolled Agents
Best for: Business owners needing tax, books, payroll and estate in one firm
Website: krtaxes.com
K&R Strategic Partners operates from 6861 E Main Street in Mesa — not Phoenix — but serves Phoenix business owners across the full scope: strategic tax advisory, accounting and business performance, estate planning, trust and entity formation, payroll and IRS representation. The firm staffs both CPAs and Enrolled Agents, so planning and representation stay under one roof.
4.9 across 88 Google reviews. K&R files in all 50 states and ranks third here for owners who want tax, books, payroll and estate planning from a single team.
The honest caveat: the office is in Mesa, roughly 20 to 35 minutes from central Phoenix. There is no Phoenix location. If walking into a Phoenix office matters more than breadth of capability, several firms on this list serve Phoenix directly.
4. ProVision, PLC
Best for proactive tax strategy
Rating: 4.8 / 5 (83 Google reviews, as of July 2026)
Location: Phoenix (Downtown / 85004) — Credentials: CPA
Best for: Proactive tax strategy and wealth advisory
Website: provisionwealth.com
ProVision, PLC operates from 382 E Palm Lane in downtown Phoenix and positions itself as a tax strategy firm rather than a pure preparation shop. The focus is building net worth through leveraged investment and sophisticated tax management — for owners and investors who want their accountant actively structuring savings rather than filing what happened last year.
Services cover full-service accounting, tax strategies, tax consulting and standard tax preparation. The firm publishes a Wealth Evaluator Tool on its website for clients to model financial goals before engaging.
4.8 across 83 Google reviews. A good fit if your primary need is proactive planning and wealth-oriented advisory. Less suited to owners who need basic bookkeeping and payroll — the orientation is strategy, not operational accounting.
5. Tax Debt Resolutions
Best for IRS debt resolution
Rating: 5.0 / 5 (361 Google reviews, as of July 2026)
Location: Phoenix (85023) — Credentials: Tax resolution firm
Best for: Resolving outstanding IRS and state tax debt
Website: taxdebtresolutionsllc.com
Tax Debt Resolutions operates from 18441 N 25th Avenue in North Phoenix and specialises in resolving outstanding tax debt with the IRS and state agencies. This is not a general CPA practice — it is a focused tax relief firm for individuals and businesses who already owe and need representation to negotiate offers in compromise, installment agreements or penalty abatement.
5.0 across 361 Google reviews — the highest review volume on this list by a wide margin. That count reflects the firm's throughput and the intensity of relief work.
If you are current on taxes and need a CPA for planning, this is not the right fit. If you owe and the IRS is in contact, it is the most-reviewed option in Phoenix.
6. Duran Business Group
Best bilingual full-service firm
Rating: 4.7 / 5 (147 Google reviews, as of July 2026)
Location: Phoenix (85016) — Credentials: Certified accountants
Best for: Bilingual English/Spanish business accounting
Website: duranbusiness.com
Duran Business Group operates from 2633 E Indian School Road with 31 professionals serving clients across 16 or more states. Over 19 years of experience, with fully bilingual English and Spanish services — a meaningful differentiator in a metro where a large share of the population speaks Spanish at home.
Services cover accounting, tax preparation, multi-state payroll, business consulting and IRS representation. The firm hosts the Cuentas Claras podcast on small business financial topics in Spanish.
4.7 across 147 Google reviews. The rating is slightly lower than the top three, but the team size and bilingual infrastructure put Duran in a different category. A strong pick for Spanish-speaking business owners who want a firm that works natively in both languages.
7. Brandon Keim, Tax Attorney
Best for tax controversy and IRS litigation
Rating: 5.0 / 5 (71 Google reviews, as of July 2026)
Location: Phoenix (Downtown / 85004) — Credentials: JD (Tax Attorney)
Best for: Tax controversy and IRS litigation
Website: keimtaxlaw.com
Brandon Keim is a tax attorney at Frazer Ryan Goldberg & Arnold LLP, an established Phoenix litigation firm, practising from 1850 N Central Avenue, Suite 1800. The focus is tax law — the legal side of IRS disputes — rather than tax preparation or accounting.
If you are facing an audit that has escalated into a legal matter or a complex tax controversy, a tax attorney provides attorney-client privilege that a CPA or Enrolled Agent cannot. The trade-off is scope: this is not where you go for annual filing or bookkeeping.
5.0 across 71 Google reviews. The right engagement when the problem is legal, not computational. Most taxpayers will never need a tax attorney, but those who do should seek one specific to tax.
8. Owens & Bondell PLLC
Best for dental and medical practices
Rating: 5.0 / 5 (27 Google reviews, as of July 2026)
Location: Phoenix (85016) — Credentials: CPA
Best for: Dental and medical practice accounting
Website: obcpas.com
Owens & Bondell PLLC has operated from 5353 N 16th Street in Phoenix since 1981. The firm provides accounting, tax preparation, consulting and payroll for small businesses, with a stated specialisation in the dental and medical industry.
The team includes Stephen L. Owens, William L. Owens, Matthew A. Bondell and Jonathan Smith. The healthcare focus matters — practice valuation, associate buy-ins and the revenue cycle of a dental office are different enough from general small business accounting that sector expertise counts.
5.0 across 27 Google reviews. Modest review count, but over 40 years of continuous operation speaks for itself. Best fit for dental or medical practice owners who want a CPA firm that already knows their industry.
9. Heidenreich & Heidenreich, CPAs, PLLC
Best for Ahwatukee and South Phoenix
Rating: 5.0 / 5 (30 Google reviews, as of July 2026)
Location: Phoenix (Ahwatukee / 85044) — Credentials: CPA
Best for: Ahwatukee and South Phoenix residents
Website: ahwatukeecpas.com
Heidenreich & Heidenreich, CPAs, PLLC serves the Ahwatukee Foothills community from 10201 S 51st Street, Suite 170 — the southern edge of Phoenix, well below Baseline Road and the I-10. For residents and business owners here, a local CPA firm avoids the 30-minute drive to Midtown or North Phoenix during tax season.
The firm positions itself as a local Ahwatukee tax preparation and CPA practice for individual and business clients in the 85044 zip code.
5.0 across 30 Google reviews. CPA firms south of Baseline with visible review histories are genuinely rare. If you live or operate a business in Ahwatukee, South Tempe or western Chandler, proximity alone puts this firm on your short list.
10. Caldwell Muhlenbruch CPA, PC
Best for continuity and long-term relationships
Rating: 4.8 / 5 (21 Google reviews, as of July 2026)
Location: Phoenix (85022) — Credentials: CPA
Best for: Long-term small business relationships
Website: cmtaxcpa.com
Caldwell Muhlenbruch, P.C. has operated from 706 E Bell Road in North Phoenix since 1981 — over four decades of continuous practice. Services cover tax planning and preparation, small business bookkeeping, payroll and individual tax returns.
The team includes Jamie Muhlenbruch, CPA, an Arizona State University graduate with the firm since 2011, and Katlyn Knippenberg, pursuing CPA certification with degrees from Grand Canyon University.
4.8 across 21 Google reviews. The lowest review count on this list, but 40 years of local practice is its own credential. A solid choice for small business owners near Bell Road who value continuity — working with the same firm and the same people, year after year.

Questions to Ask Before You Hire
“Do you need a CPA, an Enrolled Agent, or a tax attorney?” CPAs hold state licenses with broad accounting authority. Enrolled Agents are federally licensed with unlimited IRS representation rights. Tax attorneys add attorney-client privilege and can litigate. Most individuals and small businesses need a CPA. If you owe back taxes, an EA or firm staffing both is practical. If the IRS has filed suit, you need an attorney.
“Is this firm a specialist or a generalist?” A general CPA handles common situations — individual returns, small business tax, bookkeeping. Some problems need a specialist: a dental practice, a bilingual engagement, a tax debt, a partnership dispute. If your situation has a clear label, start with a firm that already works in that space.
“Does the firm's location matter for my work?” Phoenix is 517 square miles. If you want in-person meetings, pick someone close. If your work goes through a secure portal and email, geography matters less than competence. Several firms on this list, including K&R, serve Phoenix from outside the city centre.
Frequently Asked Questions
What is Arizona's individual income tax rate?
Arizona applies a flat 2.5% individual income tax rate to all taxable income, regardless of filing status or income level — one of the lowest state rates in the country. Federal income tax applies separately, and Arizona conforms to most federal provisions for calculating taxable income.
Does Phoenix have a local income tax or business tax?
No local income tax — Arizona does not allow municipalities to levy one. However, Phoenix requires businesses to hold a Transaction Privilege Tax (TPT) license. TPT is levied on the seller's privilege of doing business, not on the buyer. If you operate a business in Phoenix, TPT compliance is a routine filing obligation.
Do I need a CPA or can I use any tax preparer in Arizona?
Arizona does not require a license for paid tax preparation. However, only CPAs, Enrolled Agents and attorneys hold unlimited representation rights before the IRS. If you run a business, file in multiple states, or face audit risk, working with a credentialed professional provides a meaningful safety margin.
Does Arizona have an estate or inheritance tax?
No. Arizona imposes no state estate tax and no inheritance tax. Estate planning in Phoenix is driven by the federal estate tax, which applies above the federal exemption threshold. Gifting strategies, trust structures and entity planning remain relevant at the federal level.
How do I verify that a CPA is licensed in Arizona?
The Arizona State Board of Accountancy maintains a public license lookup at azaccountancy.gov. Enrolled Agent credentials can be verified through the IRS Return Preparer Office. Both checks take under a minute and are worth doing before engaging any firm.
