How to Choose a Tax Strategist in San Diego: 8 Questions to Ask Before You Hire

You're pulling in $300K-plus in San Diego, filing a California tax return with that punishing 13.3% top rate, watching the SALT cap eat your deduction, and carrying equity compensation from a local biotech or tech company. You know you need more than the preparer who did your taxes when you were making $80K. But how do you actually tell a qualified tax strategist from someone who just calls themselves one? A bad hire doesn't just waste your money on fees — it costs you in missed strategy, FTB exposure, and tax-code complexity that a generalist has no business touching. Here are the eight questions that separate a San Diego tax strategist who adds value from one who just fills forms.

Why San Diego Needs a Different Kind of Tax Pro

There's a wide gap between a tax preparer and a tax strategist. A preparer takes last year's numbers, plugs them into software, and files. A strategist structures your income, entity choices, investment timing, and equity compensation to minimize what you owe before you file.

That gap matters more in San Diego than almost anywhere else. California's 13.3% top marginal rate is the highest state income tax in the country. The SALT (State and Local Tax) cap limits your federal deduction for state taxes to $10,000 — hitting high earners in high-tax states like California disproportionately. And San Diego's economy is dense with equity compensation: Qualcomm, Illumina, ResMed, and a sprawling biotech corridor mean RSUs, ISOs, and NSOs are common compensation tools that create complex tax events.

A generic national tax professional who mostly works with W-2 employees in low-tax states simply won't have the California-specific muscle you need.

Credential Check: EA, CPA, or Something Else?

Before you even ask the eight questions, understand what the letters after a name mean — in California context.

CPA (Certified Public Accountant). CPAs are licensed by the California Board of Accountancy. They pass the Uniform CPA Exam and must complete continuing education. Many CPAs specialize in tax, but many focus on audit or general accounting — so "CPA" alone doesn't guarantee tax-strategy depth. Ask whether tax is their primary practice area.

EA (Enrolled Agent). EAs are federally licensed by the U.S. Department of the Treasury. They are tested specifically on tax law and have unlimited representation rights before the IRS — including audits, appeals, and collections. California does not license EAs separately, but the credential is nationally recognized. For a high earner who might face an IRS or FTB audit, an EA's representation rights are valuable. Many EAs who practice in California develop deep state-level expertise precisely because federal tax law is their core focus.

CFP (Certified Financial Planner) or CPA/PFS. These professionals may have tax knowledge as part of broader financial planning. They can be valuable for coordinated strategy, but tax is typically one competency among many.

For a $300K+ earner in San Diego, the credential matters less than the answer to the next question. A CPA who has handled fifty San Diego tech executives' equity compensation is more valuable than an EA who mostly files Schedule Cs for freelancers — and vice versa.

Question 1: "What's your experience with California FTB audits?"

The California Franchise Tax Board audits high earners at a significantly higher rate than the IRS does. FTB has its own audit triggers — large itemized deductions, residency disputes (people claiming to have left California while maintaining a home here), and SALT addback adjustments are common flags.

A qualified San Diego tax strategist should be able to tell you:

• How many FTB audit representations they've handled in the past three years
• The most common California-specific audit trigger they see for $300K+ earners
• How they handle residency audits (a major risk for anyone who spends time between San Diego and a lower-tax state)

If they've never dealt with the FTB, proceed with caution. California is not a "learn on the job" state for tax representation.

Question 2: "How do you handle equity compensation — RSUs, ISOs, and NSOs?"

San Diego's status as a biotech and technology hub means a large share of high earners in the region hold company equity. RSUs (Restricted Stock Units), ISOs (Incentive Stock Options), and NSOs (Non-Qualified Stock Options) each create different tax events at grant, vest, exercise, and sale.

A competent strategist should ask you detailed questions about your equity before you can ask them all your questions. They should want to know:

• What type of equity you hold
• Whether you've exercised ISOs (and whether the AMT was calculated correctly)
• The spread between your grant price and current valuation
• Whether your company has had a liquidity event recently

If the conversation about your equity compensation stays at the "we'll enter the numbers from your 1099-B" level, you are talking to a preparer, not a strategist.

Question 3: "What's your approach to the SALT cap and California's 13.3% rate?"

The Tax Cuts and Jobs Act capped the state and local tax deduction at $10,000 per year. For a San Diego high earner paying $40,000–$80,000+ in California state income tax, that's a massive lost deduction.

California created a workaround — the Pass-Through Entity Tax (PTET) — that allows certain business owners to deduct state taxes at the entity level rather than the individual level, bypassing the $10,000 SALT cap. This is one of the few legitimate SALT-cap strategies available, and it's California-specific.

A strategist should be able to walk you through:

• Whether you qualify for PTET (it applies to pass-through entities like S-corps, LLCs, and partnerships)
• Whether electing PTET makes sense for your specific income mix
• Other strategies for managing California's high effective rate, such as income timing, tax-advantaged investments, and multi-state allocation

If they can't explain PTET without looking it up, they are not current on California-specific strategy.

Question 4: "Who else works on my file, and how do you coordinate?"

Tax strategy at the $300K+ level is not a solo sport. Your tax strategist should coordinate with your estate attorney (for trust and estate planning), your financial advisor (for investment location and withdrawal sequencing), and potentially your corporate attorney (if you have entity structures).

Ask specifically:

• Do you work primarily solo, or with a team that includes specialists?
• Do you have a protocol for coordinating with my other professional advisors?
• Will you review my estate plan for tax implications, or do I need to connect you with my attorney?

A strategist who insists they handle everything alone, without collaborating with your existing advisor team, is either overpromising or underdelivering.

Question 5: "How are you compensated, and what will my total cost be?"

Fee structures vary widely. You want clarity before engagement:

• Flat annual retainer (common for ongoing strategy — $3,000–$15,000+ depending on complexity)
• Hourly billing ($250–$600/hour for specialized California tax work)
• Percentage of tax savings (controversial — regulated for CPAs in many states, and creates a potential incentive misalignment)
• Compliance-only pricing (a separate, lower fee for just filing returns)

Ask for an engagement letter that spells out what's included in strategy vs. what costs extra. A red flag is any strategist who cannot give you a reasonable estimate before you sign.

Question 6: "What conflicts of interest should I know about?"

Some tax professionals also sell financial products, refer clients to affiliated investment vehicles, or have arrangements that create conflicts. California has strict disclosure requirements, but not all practitioners meet them proactively.

Ask directly: "Do you receive any compensation for recommending specific investments, insurance products, or legal services?" If the answer is anything other than a clear "no" or a full disclosure with your consent process, push harder.

Question 7: "Who are your typical clients?"

The best indicator of fit is the strategist's existing client base. Ask:

• What income range do most of your clients fall into?
• What industries do they work in?
• Do you serve many San Diego-based professionals?
• What percentage of your clients face California FTB audits or have equity compensation?

If their typical client earns $150K and has a single W-2, they may not have the depth for a $300K+ earner with equity and entity complexity.

Question 8: "What does ongoing communication look like?"

Tax strategy is year-round, not a January-to-April sprint. Ask:

• How often do you meet with clients outside of filing season?
• What triggers a check-in (major life event, tax law change, equity event)?
• How quickly do you respond to client questions during the year?

A strategist who disappears from May through December is doing compliance, not strategy.

Red Flags and Green Lights

Red flags to watch for:

• Cannot clearly explain EA vs CPA vs CFP distinctions
• Has never represented a client before the FTB
• Promises specific savings without reviewing your prior returns
• Doesn't ask detailed questions about your equity compensation, business structure, or residency status
• Cannot explain PTET or the California SALT cap workaround
• Won't put the engagement scope in writing
• Has a client base that looks nothing like your profile

Green lights to look for:

• Asks more questions than they answer in the first consultation
• Reads your prior return before meeting and identifies missed opportunities
• Can articulate specific California tax code sections relevant to your situation
• Has a clear, documented process for year-round engagement
• Readily coordinates with your existing advisors
• Gives honest answers about what they don't handle and refers to specialists

Know What You're Hiring For

A San Diego tax strategist for a $300K+ earner is not a luxury — it is a hedge against overpaying a state that already takes 13.3% of your top income. The right strategist pays for themselves by structuring your equity, navigating the SALT cap, keeping you FTB-compliant, and planning ahead instead of filing retroactively.

Use these eight questions as your screening framework. A strategist who answers them confidently, specifically, and with California context is worth an engagement letter. One who dodges, generalizes, or can't speak to San Diego's unique tax environment will cost you more than their fee.

FAQ

What is the difference between a tax preparer and a tax strategist?

A tax preparer inputs last year's financial data into software and files your return. A tax strategist works year-round to structure your income, entity choices, equity compensation, and investment timing to minimize taxes before filing. High earners in California benefit significantly from the latter.

What is the California PTET and how does it help with the SALT cap?

The Pass-Through Entity Tax is a California-specific workaround that allows certain business owners (S-corps, LLCs, partnerships) to deduct state taxes at the entity level, bypassing the $10,000 SALT cap on individual deductions. It is one of the few legitimate strategies for high earners in high-tax states to reduce their federal tax burden.

How common are FTB audits for high earners in California?

The California Franchise Tax Board audits high-income taxpayers at a higher rate than the IRS. Common triggers include large itemized deductions, residency changes, SALT addback adjustments, and income reported from pass-through entities. Having a strategist with FTB representation experience is valuable.

Should I hire a CPA or an EA for tax strategy in California?

Both credentials can serve you well. CPAs are licensed by the California Board of Accountancy and may have broader accounting knowledge. EAs are federally licensed and tested specifically on tax law with unlimited IRS representation rights. The credential matters less than the practitioner's specific experience with California high-income tax situations, FTB audits, and equity compensation.

How much does a tax strategist in San Diego typically cost?

Fees vary widely based on complexity. Flat annual retainers for ongoing strategy typically range from $3,000 to $15,000 or more. Hourly rates for specialized California tax work run $250 to $600 per hour. Many strategists offer separate pricing for compliance (return filing) vs. strategy (year-round planning). Always ask for a written engagement letter before committing.
