Start with the decision you need help making
If you are deciding how to choose a tax advisor, bring the decision you need to make in the next few months. An owner preparing to sell a business needs a different review from an investor trying to reconcile rental depreciation. State the deadline, the entities involved and what you expect the advisor to deliver before comparing firms.
Choose the firm that can explain its process for your facts, identify the responsible professional and put the work in writing. A persuasive savings estimate is not a substitute for that evidence. This guide gives you a repeatable interview, an example of comparing incomplete proposals and a scorecard you can use with AE or another shortlisted firm.
Verify the person doing the work
Ask who will review your records, who signs any prepared returns and who would handle a notice. The IRS distinguishes credentials from representation rights: CPAs, enrolled agents and attorneys have unlimited representation rights before the IRS. A PTIN alone does not establish those rights. Check the relevant license or enrollment and ask about experience with your type of work. Review the IRS credential guidance.
The IRS choosing-a-professional guide links to its preparer directory. The directory is useful for checking listed qualifications; absence alone does not establish that a preparer cannot provide quality service. Credentials are one part of a hiring decision. They do not establish that someone regularly handles your particular entity group, state footprint or property records.
Use the same six interview questions with every firm
| Ask | A useful answer includes |
|---|---|
| Which of my decisions will you evaluate? | Your actual transaction, entities, records and timing; not a list of strategies everyone receives. |
| Who owns the recommendation? | A named role or professional, how review works, and who communicates with you. |
| What will I receive? | Written deliverables, assumptions, limitations and a review meeting. |
| Who completes each action? | Assignments to the advisor, your existing preparer, a vendor or you, with completion evidence. |
| What is outside the fee? | Preparation, amendments, studies, bookkeeping and legal work stated separately. |
| What happens when facts change? | Support period, response process, renewal terms and the trigger for a new quote. |
An advisor can reasonably need your records before estimating an outcome. Treat a request for evidence as part of the process. If the initial answer is vague, ask for a sample deliverable with client information removed or a written description of the proposed work. Do not request another client’s private documents.
Worked example: a property purchase with an existing CPA
Hypothetical situation: a business owner expects to buy a rental in 60 days and already has a preparer. Firm A offers a short strategy call. Firm B offers a written review of the purchase facts and a handoff to the preparer. Neither proposal includes a cost segregation study or return preparation. There is no assumed deduction or savings amount in this example.
The immediate question is whether you need a call or a documented decision before signing the purchase contract. Ask both firms who will review the closing facts, assess what records are missing and communicate findings to the preparer. If Firm B’s handoff is important to you, put its content and delivery date in the agreement. If Firm A can provide the same work as a separately quoted project, compare that complete price instead.
The example also gives you a reason to pause: if the property facts are not available or the advisor cannot deliver before your decision date, a broad planning engagement may not resolve the immediate problem. Ask what can be reviewed now and what must wait.
Score the proposal using evidence, not a sales promise
| Criterion | Maximum | Evidence to record |
|---|---|---|
| Relevant work and decision timing | 25 | Your decision is explicitly in scope and the delivery date is useful. |
| Professional responsibility | 20 | The responsible roles, credentials and review process are clear. |
| Written analysis and limitations | 20 | Deliverables and assumptions are identified. |
| Implementation and preparer coordination | 20 | Every action has an owner and handoff requirement. |
| Complete cost and support terms | 15 | Exclusions, support period and additional charges are stated. |
Use the total to organize questions, not to conceal a serious omission. An unresolved deadline, unsupported credential claim or unclear required fee needs resolution regardless of the score. A firm can also be the wrong fit despite a strong proposal when its scope addresses a problem you do not have.
Make the next call productive
Prepare a one-page situation summary: entities, relevant states, recent returns, current financial statements, planned transactions and the decision date. Ask how the firm securely receives documents before sending sensitive records. You can start with AE’s published service pricing and engagement scope guide.
AE publishes business-owner and real estate advisory services. Use the same questions here to evaluate AE: the signed agreement should identify your work, professional responsibilities and any separately priced services. Book a call with AE to discuss those facts. This guide is general information; it does not determine which tax position or engagement is appropriate for you.
Frequently Asked Questions
Should I choose a CPA or an enrolled agent?
Either credential can be relevant. Compare experience with your actual work, verify the credential, and identify who is responsible for planning, preparation and representation. A credential alone does not settle service fit.
Can I keep my current return preparer?
Ask whether the advisory firm will coordinate with your preparer and what the handoff includes. Confirm both parties agree on responsibilities; do not assume filing is included in the planning fee.
What should I ask before signing?
Confirm written deliverables, the decision deadline, implementation owners, exclusions, full required cost and support period. Resolve missing terms before relying on a projected benefit.
