CPA, enrolled agent, or tax attorney: what's the difference?
- CPAs are licensed by state boards of accountancy and work across tax, accounting, and audit.
- Enrolled agents are licensed by the IRS after passing an exam or through qualifying IRS experience.
- CPAs, enrolled agents, and attorneys all have unlimited rights to represent taxpayers before the IRS.
- Tax attorneys bring legal training for disputes, litigation, and complex structuring.
What does a CPA do beyond filing?
- Year-round projections that inform estimated payments, Roth conversions, and the timing of sales.
- Guidance on entity choice and compensation for business owners.
- Responding to IRS and state notices and representing you in audits.
- Coordinating with your financial adviser and estate attorney on shared decisions.
Why does equity compensation raise the stakes?
- Brokers often report RSU and ESPP sales with zero or incomplete basis, so the gain can look larger than it is.
- Exercising ISOs can create alternative minimum tax without any sale.
- Withholding on stock income often falls short, so estimated payments may be needed.
- A CPA who regularly handles equity compensation can catch these issues before filing.
How do you find and vet a CPA?
- License status can be checked with your state board; in California, that's the California Board of Accountancy.
- The IRS Directory of Federal Tax Return Preparers lists credentialed preparers.
- Ask about experience with situations like yours, how fees are set, and who does the work.
- Ask whether they offer year-round planning or return preparation only.
What are red flags in a tax preparer?
- Fees based on a percentage of your refund.
- Promises of a large refund before seeing your documents.
- Refusing to sign the return as the paid preparer, or asking you to route your refund to their account.
- You remain responsible for everything on your return, even when a preparer makes the mistake.
Key takeaways
- Complexity, not income alone, is the usual signal that software is no longer enough.
- CPAs, enrolled agents, and tax attorneys can all represent you before the IRS.
- Verify credentials and avoid refund-based fees.
- Rubric doesn't prepare tax returns; we coordinate with your CPA.
