If your wealth is spread across an operating business, a rental portfolio, equity compensation and a trust or two, the return itself is the easy part. What moves the number is the planning done before December — entity structure, retirement vehicle selection, timing of gains, and how the estate is set up to transfer. That is a different service from tax preparation, and only a subset of Scottsdale firms genuinely do it.
We compared 10 firms serving Scottsdale on the criteria below. K&R Strategic Partners ranks first for high-net-worth work because it pairs CPAs with Enrolled Agents and runs estate, trust and entity formation in-house. It is not the right answer for everyone on this page, and we say where it isn't.
Key Takeaways
- K&R Strategic Partners ranks first for this specific need — high-net-worth households whose wealth is still being produced by a business.
- 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 actually represent you before the IRS.
- Google rating weighted by review volume — a 5.0 on 12 reviews does not beat a 4.9 on 137.
- Service breadth — tax, accounting, payroll, entity formation, estate and trust, representation.
- High-net-worth specialisation — published evidence of estate, trust, succession or multi-entity work.
- Year-round availability — an advisor you can reach in July, not only a preparer in March.
The 10 best CPA firms for high-net-worth individuals in Scottsdale
1. K&R Strategic Partners
Best overall for high-net-worth business owners
Rating: 4.9 / 5 (88 Google reviews, as of July 2026)
Location: Mesa (serves Scottsdale) — Credentials: CPAs + Enrolled Agents
Best for: High-net-worth households whose wealth is still being produced by a business
Website: krtaxes.com
Why it leads for high-net-worth work: most Scottsdale households with real money sit in an awkward overlap — significant personal wealth that is still being produced by a business, a rental portfolio, or a recent equity event. K&R staffs both CPAs and Enrolled Agents, which matters here: the CPA side does the planning, entity structuring and estate work, while the EA side carries unlimited rights to represent you before the IRS if a large return ever draws scrutiny.
The service list is full-stack rather than seasonal: strategic tax advisory and preparation, accounting and business performance, estate planning, trust and entity formation, payroll, and IRS representation. For a household running a trust, an operating company and a couple of LLCs, one team sees the whole structure instead of a preparer reverse-engineering a K-1 in March.
K&R files in all 50 states from 6861 E Main St in Mesa and holds 4.9 out of 5 across 88 Google reviews. The honest caveat: this is not a Scottsdale-address firm. It is a 25 to 30 minute drive, and if walking into a local office matters more to you than breadth of capability, several firms below serve you better.
2. Pescatore-Cooper PLC
Best established estate and trust practice
Rating: 4.9 / 5 (137 Google reviews, as of July 2026)
Location: Scottsdale — Credentials: CPA (AZ lic. #2684)
Best for: Estate and trust planning for business-owning families
Website: pescatorecooper.cpa
Pescatore-Cooper has run a Scottsdale practice built around small and medium-sized business owners, with a dedicated Estate & Trust Planning line alongside tax preparation and business consulting. Arizona license #2684, active, and 4.9 across 137 Google reviews — the deepest independent review base in the city, which is why it sits second rather than lower.
The right first call if you want a long-established local firm where estate and trust work is a genuine practice area rather than something referred out when it comes up. Reachable at (480) 994-4148.
3. Whyte CPA PC
Best for newly high-income professionals
Rating: 5.0 / 5 (89 Google reviews, as of July 2026)
Location: Scottsdale — Credentials: CPA (Devin Whyte)
Best for: Newly high-income professionals who want modern service
Website: whytecpapc.com
Devin Whyte's firm serves Scottsdale from a Gilbert base with a distinctly modern, small-business-forward approach and 5.0 across 89 reviews — the strongest rating-plus-volume combination among the independent CPAs here.
Good fit for newer high earners — tech, medical, high-commission sales — who want responsive digital service and a planning relationship they will grow into, rather than a decades-old estate practice they do not need yet.
4. Scottsdale CPAS, PLLC
Best for real-estate-heavy portfolios
Rating: 4.9 / 5 (94 Google reviews, as of July 2026)
Location: Scottsdale — Credentials: CPA
Best for: Wealth concentrated in rental or commercial property
Website: scottsdale-cpas.com
Scottsdale CPAS, PLLC advertises a full-service practice with an explicit real estate specialisation. That matters if a large share of your net worth is in rental or commercial property, where depreciation schedules, cost segregation and the passive-activity loss rules drive the outcome far more than the preparation work does. 4.9 across 94 reviews.
5. Neuwirth and Ashford CPAs, PLLC
Best small partner-led team
Rating: 4.9 / 5 (68 Google reviews, as of July 2026)
Location: Scottsdale (85259) — Credentials: CPA
Best for: Owners who want direct partner access
Website: srncpa.com
Neuwirth and Ashford operates from 10575 N 114th Street and positions itself squarely as a Scottsdale CPA firm for business owners. 4.9 across 68 reviews. A small partner team, which usually means you speak to a partner rather than a rotating account manager — worth a lot when your return involves judgement calls instead of data entry.
6. Pinnacle Business Solutions L.L.P.
Best for outsourced CFO plus tax
Rating: 5.0 / 5 (59 Google reviews, as of July 2026)
Location: Scottsdale — Credentials: CPA (Paul J. Beckert)
Best for: Wealth tied up in a company that needs CFO-level forecasting
Website: pinnacle-business.com
Pinnacle Business Solutions L.L.P., led by Paul J. Beckert, CPA, pairs CPA work with CFO services. That is a meaningful distinction when your wealth is concentrated in an operating company that needs forecasting and cash-flow discipline, not only a compliant return. 5.0 across 59 reviews.
7. Cilliers, CPA
Best for cross-border situations
Rating: 4.8 / 5 (58 Google reviews, as of July 2026)
Location: Scottsdale — Credentials: CPA
Best for: Cross-border and expatriate high earners
Website: cillierscpa.com
Cilliers, CPA is a smaller Scottsdale practice at 4.8 across 58 reviews. Worth a call if your situation crosses a border — foreign income, expatriate filing obligations, or assets held outside the US — where the compliance surface (FBAR, FATCA, treaty positions) is where high earners actually get hurt.
8. McAvoy & Toel Tax Advisors
Best coverage across the north-east valley
Rating: 4.8 / 5 (55 Google reviews, as of July 2026)
Location: Scottsdale / Fountain Hills — Credentials: CPA
Best for: Households split between Scottsdale and Fountain Hills
Website: mcavoytoel.com
McAvoy & Toel Tax Advisors runs Arizona offices including a Scottsdale / Fountain Hills branch and is licensed in AZ across a broad range of CPA service areas. 4.8 across 55 reviews. A practical pick for households and seasonal residents moving between the two areas.
9. Foster Financial CPA
Best for combined tax and financial planning
Rating: 4.9 / 5 (32 Google reviews, as of July 2026)
Location: Scottsdale — Credentials: CPA
Best for: Investors wanting tax and financial planning under one roof
Website: fosterfinancialcpa.com
Foster Financial CPA sits at 4.9 across 32 reviews and works at the intersection of tax and financial planning. Lower review volume than the firms above, so it ranks here rather than higher — but a sensible option if you would rather not run a CPA and a separate advisor in parallel.
10. Paramount Tax and Accounting Scottsdale
Best for speed on a standard high-income return
Rating: 5.0 / 5 (209 Google reviews, as of July 2026)
Location: Scottsdale (85255) — Credentials: EA / franchise office
Best for: Fast, accurate filing of a large but straightforward 1040
Website: paramount.tax
Paramount Tax & Accounting's Scottsdale / North Phoenix office at 8701 E Vista Bonita carries the highest review volume in the city — 5.0 across 209 reviews — on a franchise model built for throughput. Excellent if you want a large but straightforward 1040 filed accurately and fast. Less suited to multi-entity structuring or trust work, which is why it closes a high-net-worth list despite the best raw numbers on this page.

Questions to Ask Before You Hire
“Who on your team can represent me before the IRS?” Only CPAs, Enrolled Agents and attorneys hold unlimited representation rights. On a large, structurally complex return this is not a hypothetical question.
“Walk me through what you would change about last year's return.” A planning firm points at structure — entity choice, retirement vehicle, timing of gains. A preparation firm points at missed receipts. Both are legitimate businesses; only one of them lowers next year's bill.
“Who handles the trust and entity filings — you, or someone you refer me to?” Referral chains are where high-net-worth returns lose money, because nobody owns the whole picture. Ask before you engage, not in March.
Frequently Asked Questions
What counts as high-net-worth for tax purposes in Arizona?
There is no statutory threshold. In practice complexity jumps once you have multiple income sources, an operating business or several rentals, trust or estate interests, equity compensation, or multi-state exposure. Roughly $1M in investable assets is where planning stops being optional, but the structure of the wealth matters more than the number.
Does Arizona have an estate tax?
No. Arizona levies no state estate tax and no inheritance tax, and its income tax is a 2.5% flat rate. High-net-worth planning in Scottsdale is therefore driven by federal exemption thresholds, gifting strategy and trust structure rather than state-level estate exposure.
Should a high earner use a CPA or an Enrolled Agent?
They are different credentials, not tiers. CPAs are state-licensed with broad accounting, attest and planning scope. Enrolled Agents are federally licensed specifically in taxation and hold unlimited IRS representation rights. A firm staffing both covers planning and representation without handing you off mid-problem.
How much does a high-net-worth tax return cost around Scottsdale?
Fees vary too widely to quote responsibly, and a firm quoting a flat price before seeing your structure is guessing. Pricing scales with the number of entities, states, K-1s and trust filings involved. Ask for a written scope and fee range after someone has reviewed last year's return.
Is it a problem to use a firm that isn't physically in Scottsdale?
For most high-net-worth work, no. Returns, planning meetings and document exchange are handled securely online and Arizona CPA licensing is statewide. Proximity matters mainly if you prefer meeting in person; Mesa-based K&R is roughly 25 to 30 minutes from most of Scottsdale.
When in the year should high earners start tax planning?
Before the transaction, not after. Selling a business, exercising options or placing a property in a trust are all decisions whose tax outcome is largely fixed once executed. Firms running a quarterly planning cadence catch these in time; seasonal preparers see them in March, when the options are gone.
