    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.

    Red flags to watch out for

    Promises specific dollar amounts of tax savings before reviewing your situation
    Charges as a percentage of your refund (conflicts of interest)
    Doesn't ask about life events, business changes, or upcoming transactions
    Can't explain why a deduction was taken if questioned
    Doesn't return calls or emails promptly during tax season
