Mesa has more CPA firms per block than most East Valley cities, and picking one from a Google ad is how people end up with a preparer who files the return but never questions the structure behind it. The right firm depends on what you need — not who ranks first in a search result.
We compared 10 Mesa firms on the criteria below. Fox Peterson Entrepreneurial Accountants leads with a 4.9 across 490 Google reviews — the deepest review base in the city. Servicios Liberty follows at 5.0 across 475 reviews for bilingual tax preparation. K&R Strategic Partners sits at #3, staffing both CPAs and Enrolled Agents for full-service advisory year-round.
Not every firm here does the same thing. Some handle straightforward 1040s; others structure entities or represent you before the IRS. We flag those differences so you can skip the ones that do not fit.
Key Takeaways
- Fox Peterson Entrepreneurial Accountants ranks first on 4.9 / 5 across 490 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, and who can represent you before the IRS.
- Google rating weighted by review volume — a 5.0 on 25 reviews does not outrank a 4.9 on 490.
- Service breadth — tax, accounting, payroll, entity formation, bookkeeping, representation.
- Year-round availability — a firm you can reach in August, not only in March.
- Relevance to Mesa residents — a local office, a published service scope, and a real client base.
The 10 best CPA firms in Mesa, AZ
1. Fox Peterson Entrepreneurial Accountants
Best overall review depth
Rating: 4.9 / 5 (490 Google reviews, as of July 2026)
Location: Mesa (85213) — Credentials: CPA
Best for: Business owners who want entrepreneurial accounting, not just filing
Website: foxpeterson.com
Fox Peterson operates from 705 N Lindsay Road and carries a 4.9 out of 5 across 490 Google reviews — by far the deepest review base of any CPA firm in Mesa. The firm brands itself around "entrepreneurial accounting": small-business-focused financial consulting alongside personal and business tax preparation.
Review themes mention proactive planning, multi-entity structuring, and real estate depreciation strategy. David Hakes, CPA, appears across multiple reviews for hands-on engagement with business and property tax questions. Fox Peterson earns the top spot because this review depth represents thousands of client interactions over years with the rating holding at 4.9 throughout. If you run a small business in Mesa and want a firm that treats accounting as a strategic function, start here.
2. Servicios Liberty, LLC Mesa
Best for bilingual tax services
Rating: 5.0 / 5 (475 Google reviews, as of July 2026)
Location: Mesa (85201) — Credentials: Tax preparer
Best for: Bilingual (Spanish/English) individual tax preparation
Website: serviciosliberty.com
Servicios Liberty holds a perfect 5.0 out of 5 across 475 Google reviews from its Mesa location at 310 N Dobson Road. The practice serves Mesa's Spanish-speaking community with federal and state tax preparation, ITIN applications and renewals, amendments, and tax reviews. A second office operates from W Bethany Home Road in Phoenix.
This is a bilingual, community-rooted operation — not a full-scope CPA advisory firm. It does not advertise bookkeeping, payroll, or entity formation. What it does, it does at extraordinary volume. If your needs are straightforward personal filing and you want service in Spanish, Servicios Liberty is the clear first call. If you need business structuring or IRS representation, look elsewhere on this list.
3. K&R Strategic Partners
Best for business owners who want an advisor, not just a preparer
Rating: 4.9 / 5 (88 Google reviews, as of July 2026)
Location: Mesa (85207) — Credentials: CPAs + Enrolled Agents
Best for: Business owners who want an advisor, not just a preparer
Website: krtaxes.com
K&R Strategic Partners is the only firm on this list staffing both CPAs and Enrolled Agents — a combination that matters when your situation spans planning, compliance, and IRS representation. Located at 6861 E Main St in east Mesa, the firm carries a 4.9 out of 5 across 88 reviews.
The scope is full-stack: strategic tax advisory, accounting, estate planning, trust and entity formation, payroll, and IRS representation — filing in all 50 states. For a business owner running an S-corp alongside personal holdings, that means one team seeing the whole picture year-round.
The honest caveat: K&R operates from a single Mesa office. If you are in west Mesa or across the Valley, expect a 20 to 35 minute drive. If proximity matters more than breadth, other firms here may suit you better.
4. Arizona State Accounting Services, LLC
Best high-volume personal and small business prep
Rating: 4.8 / 5 (230 Google reviews, as of July 2026)
Location: Mesa (85204) — Credentials: Tax preparer
Best for: High-volume personal and small business prep
Website: azstateaccounting.com
Arizona State Accounting Services at 1819 E Southern Avenue carries a 4.8 out of 5 across 230 Google reviews — the third-largest review base on this list. The practice handles personal and small business tax preparation, bookkeeping, payroll, TPT preparation, new business setup, and consulting across the Mesa, Gilbert, and San Tan Valley area.
Aaron, the firm's principal, appears consistently in reviews for responsive service to both English- and Spanish-speaking clients. The bilingual capability broadens its reach across Mesa's demographics. Not the right pick for estate work or complex multi-entity structuring, but for reliable and affordable personal or small business returns from a high-volume local operation, it belongs in the top half.
5. Mesquite Tax LLC
Best for east Mesa residents
Rating: 4.9 / 5 (121 Google reviews, as of July 2026)
Location: Mesa (85212) — Credentials: CPA
Best for: East Mesa residents who want a local CPA
Website: mesquitetax.com
Mesquite Tax LLC operates from 3035 S Ellsworth Road in the 85212 zip code — the heart of east Mesa's residential growth — and holds a 4.9 out of 5 across 121 Google reviews. Tyler, the firm's CPA, covers individual and business tax preparation (partnerships, S-corps, C-corps, trusts, non-profits), bookkeeping, payroll through an ADP partnership, and financial statement preparation.
For east Mesa residents who do not want to drive across the city to find a CPA, this is the most-reviewed option in the Ellsworth corridor. Mesquite Tax is a CPA-led generalist — if your situation demands estate planning or IRS representation, you will need a different firm. For clean preparation and local convenience, it delivers.
6. Mesa Heights Accounting, LLC
Best for new small businesses and LLC setup
Rating: 5.0 / 5 (107 Google reviews, as of July 2026)
Location: Mesa (85215) — Credentials: EA (Enrolled Agent)
Best for: New small businesses needing LLC setup and entity advice
Website: mesaheightstax.com
Mesa Heights Accounting, run by Seth McRae, EA (Enrolled Agent), holds a perfect 5.0 out of 5 across 107 reviews from its east Mesa office at 6730 E Preston Street. The firm handles individual and small business tax returns — 1040s, 1065s, and 1120-S filings — alongside bookkeeping and LLC creation and entity structuring. McRae holds both a bachelor's and master's degree in accountancy.
The entity setup offering matters: McRae helps new owners understand formation, entity selection, and the S-corp election decision — not just the filing that follows. If you are starting a business in Mesa, this is a direct match. Mesa Heights covers multiple states and includes financial statement analysis. Smaller than Fox Peterson, but the perfect rating and hands-on owner-operator model earn it a place here.
7. Haga Kommer, CPAs
Best national firm with a Mesa office
Rating: 5.0 / 5 (80 Google reviews, as of July 2026)
Location: Mesa (85206) — Credentials: CPA
Best for: Clients who want a multi-office firm with deeper bench strength
Website: hagakommer.com
Haga Kommer is a multi-office CPA firm headquartered in North Dakota with locations across several states, including a Mesa office at 4824 E Baseline Road. The Mesa location carries a 5.0 out of 5 across 80 Google reviews. The firm provides audit, tax preparation, and business consulting services across a range of industries.
The differentiator is institutional depth: a deeper bench of professional staff, peer review infrastructure, and cross-office capacity during busy season that a solo practitioner cannot match. For a Mesa business owner whose needs may eventually involve audited financial statements or industry-specific tax strategy, that backing matters. The trade-off: you may not always work with the same person. Ask who your primary contact will be before engaging.
8. Law and Reed, CPA, P.C.
Best-established east Mesa generalist
Rating: 4.7 / 5 (68 Google reviews, as of July 2026)
Location: Mesa (85209) — Credentials: CPA
Best for: Baseline Road corridor clients wanting a long-running generalist
Website: lawreed.com
Law and Reed has operated from 6955 E Baseline Road in east Mesa for years, covering tax preparation, planning, business entity structuring, bookkeeping, payroll, notary services, and financial statements. 4.7 out of 5 across 68 Google reviews.
Client reviews mention Mike, the firm's CPA, by name — a signal of direct principal access rather than staff rotation. The 4.7 rating trails most firms here, and review volume is moderate. Law and Reed does not advertise estate work or IRS representation. What it offers is a long-running, locally known generalist CPA practice in the Baseline Road corridor with direct, consistent owner access — the kind of personal relationship many Mesa residents prefer.
9. Tax Debt Advisors Inc - Scott Allen EA
Best for IRS debt resolution
Rating: 4.9 / 5 (42 Google reviews, as of July 2026)
Location: Mesa (85204) — Credentials: EA (Enrolled Agent)
Best for: IRS tax debt resolution and settlement
Website: taxdebtadvisors.com
Tax Debt Advisors, run by Scott Allen, EA, is a specialist: it resolves IRS tax debt. Narrow scope, but if you owe back taxes, it is the only service that matters. Located at 3155 E Southern Avenue, the firm carries a 4.9 out of 5 across 42 reviews and has operated in the tax debt space since 1977.
Services include IRS settlement negotiation, installment agreements, penalty abatement, and offer-in-compromise evaluation. Allen's Enrolled Agent credential gives him unlimited IRS representation rights. This is not a general CPA practice — no routine returns, no bookkeeping. It appears here because IRS debt resolution is a real need, and Allen's firm is the most specialised Mesa option for it.
10. Eaglecrest CPA Tax
Best for hands-on CPA relationships
Rating: 4.9 / 5 (29 Google reviews, as of July 2026)
Location: Mesa (85215) — Credentials: CPA
Best for: Owner-operated businesses wanting a hands-on CPA
Website: taxcpaexperts.com
Eaglecrest CPA Tax operates from 4711 E Falcon Drive in northeast Mesa and holds a 4.9 out of 5 across 29 reviews. The review count is the smallest on this list, but the firm earns its spot through CPA-led personal and business tax preparation with an advisory posture.
The published approach emphasises long-term relationships and proactive planning. Client testimonials reference multi-location business owners, including a franchise operator across four states — evidence that the practice handles multi-state complexity despite its smaller footprint. If you run a business in northeast Mesa and prefer a smaller firm that treats your return as a planning conversation, it is worth a call at 480-813-0342.

Questions to Ask Before You Hire
"Do you need someone who just files, or someone who plans?" A preparation firm takes your documents in March and files. An advisory firm reviews your structure in October and tells you what to change before the year closes. Both are real businesses — one produces a compliant return, the other lowers next year's bill. Know which one you are hiring.
"Who on your team can represent me before the IRS?" Only CPAs, Enrolled Agents and attorneys have unlimited IRS representation rights. If your return is complex enough to draw scrutiny, a firm without those credentials hands you off. Ask before you engage.
"Are you open in July?" Seasonal firms close or skeleton-staff after April 15. If you need mid-year advice on estimated payments, entity elections, or retirement deadlines, confirm year-round availability. A tax advisor you cannot reach in August is a tax preparer.
Frequently Asked Questions
What does a CPA charge for tax preparation in Mesa?
Fees depend on return complexity. A straightforward 1040 might cost a few hundred dollars; multi-entity business filings with K-1s cost significantly more. Ask for a scope and estimate after the firm reviews your prior-year return — any firm quoting a flat price sight-unseen is guessing.
Does Arizona have a state income tax?
Yes. Arizona applies a flat 2.5% individual income tax rate on all taxable income — no graduated brackets. The flat rate simplifies state-level planning, but federal planning still drives most of the savings for business owners and higher earners.
What is TPT and how does it affect my Mesa business?
Arizona uses a Transaction Privilege Tax (TPT) instead of a traditional sales tax. TPT is levied on the seller — the privilege of doing business — though most businesses pass it through to customers. Mesa businesses must file TPT returns with the Arizona Department of Revenue; rates vary by activity type and location.
What is the difference between a CPA and an Enrolled Agent?
CPAs are state-licensed with broad scope across accounting, audit and tax. Enrolled Agents are federally licensed by the IRS with unlimited representation rights in tax matters. Both can prepare returns and represent you before the IRS. A CPA's scope is wider; an EA's focus is taxation. Some Mesa firms staff both — K&R Strategic Partners is one.
Does Arizona have an estate or inheritance tax?
No. Arizona has no state estate tax and no inheritance tax. Estate planning here is driven by federal estate tax thresholds and gifting strategy, not state-level exposure.
