Before You Sign With a Tax Provider, Ask These 7 Questions.

By US Biz Toolkit · October 8, 2026

Quick answer: A good proposal should explain who does the work, what it costs and what remains uncertain.

A confident sales presentation is not enough to choose a tax provider. Bring a short set of questions that makes competing proposals easier to compare. You are looking for an understandable engagement and a review process that fits your business, rather than the biggest projected number.

1 and 2: Who does the work, and what is included?

Ask who will analyse the facts, prepare any return work and answer later questions. The IRS advises checking preparer credentials and notes that paid federal return preparers need a PTIN. Ask about experience relevant to your issue as well as the precise scope of the engagement. A credential does not by itself explain what this particular contract delivers.

3: How are the fees calculated?

Request the fee structure, payment dates and excluded work in writing. Ask what happens if the review finds that the opportunity does not fit your facts. If several professionals are involved, identify their separate charges. Put the terms in a comparison table rather than relying on what you remember from a call.

4: What evidence will you review?

Ask which records the provider needs before reaching a conclusion. In a hypothetical R&D engagement, that might involve technical project records as well as financial information. In a planning engagement, it might involve upcoming decisions and current books. The point is to understand the process, not to assume that one universal document list fits every service.

5: Who implements the recommendation?

Ask how the provider will coordinate with your existing accountant, payroll service or legal adviser when needed. Request a named point of contact and an explanation of the handoff. A report that no one knows how to use can create extra work rather than clarity.

6: What support is included later?

Ask about follow-up questions, corrections and any examination-related support. Read the limits of the agreement. Do not assume that the word “support” includes every future dispute or cost. Keep the signed scope and the final deliverables together.

7: Which assumptions could change the outcome?

Ask the provider to identify unresolved facts and explain any projection. The IRS warns about exaggerated refund promises and ghost preparers. If a promise sounds unconditional before your records have been examined, ask for a clear explanation and consider another qualified opinion. You remain responsible for the information on your return.

Your next step

Compare proposals using these questions. Use the professional selector to identify the service category, then review a provider’s actual scope and terms before engaging.
