1Before You Start Looking
Clarify your tax situation type (individual, LLC, S-corp, international, crypto)
Tax law is hyper-specialized — you need someone with experience in your exact scenario.
List your income sources and structures (salary, equity, rental, business)
Complexity determines whether a generalist CPA or specialist advisor is right.
Identify your current pain point (reduce liability, fix a mistake, plan ahead, audit defense)
Different pain points require different advisors.
Gather last 2–3 years of returns to share
Good advisors will review your history to spot missed opportunities.
Note any upcoming life or business events (sale, funding round, exit)
Tax planning is most valuable before events, not after.
2Vetting Candidates
Confirm CPA or EA (Enrolled Agent) credentials
Only CPAs and EAs are federally authorized to represent you before the IRS.
Ask specifically about experience with your entity type and income structure
A CPA who only does W-2 returns can't optimize a multi-entity LLC structure.
Ask for their proactive communication frequency
The best tax advisors reach out mid-year with planning opportunities, not just at tax time.
Inquire about their stance on aggressive vs. conservative tax positions
You need alignment on risk tolerance — some advisors are too cautious, others too aggressive.
Check if they use a secure client portal for document sharing
Tax documents contain SSNs and financial data — security is non-negotiable.
3During the Engagement
Schedule a mid-year planning call (not just year-end)
Most tax moves must be made before Dec 31 — waiting until filing season is too late.
Provide documents promptly to avoid extension fees
Delays on your end often cause delays and missed deductions.
Ask about estimated quarterly tax payments if self-employed
Underpayment penalties can add up quickly without proper estimates.
Request a summary of every major tax decision and why it was made
You should understand your own tax strategy, not just sign where told.
Ask 'what would you do differently?' each year to drive improvement
Forward-looking advisors always find something to optimize.
4Wrapping Up
Request a copy of all filed returns in PDF format
You should always have your own records regardless of what the advisor stores.
Confirm the advisor's availability if you face an audit or IRS notice
Some preparers disappear after filing — you need ongoing support.
Ask for a year-end tax planning memo
A good advisor summarizes what was done and what's planned for next year.
Evaluate: did they save you more than they cost?
A great tax advisor is a profit center, not an expense.
Expert tip
Ask every tax advisor: 'What's the biggest tax mistake you see people in my situation make?' Their answer tells you whether they truly understand your scenario.
