How to Hire a CPA for Your Small Business
A decision framework, 15 interview questions, red flags, a switching checklist, and a weighted scorecard you can use with any firm, including Taxstra.
This guide is designed to help you make a good decision even if Taxstra is not the firm you hire.

The short answer
Start by defining the work you need, then evaluate accountability, planning cadence, relevant experience, security, deliverables, communication, and fees. “CPA” is a credential; it does not by itself define the service relationship.
The hiring trigger
Six signs the business has outgrown DIY or annual-only help
The right time is usually before the next entity, payroll, state, financing, or transaction decision, not after the return reports it.
- You cannot produce current, reconciled financial statements
- Tax estimates repeatedly surprise you
- Owner pay, distributions, and personal spending are mixed
- You added an entity, owner, employee, contractor, or state
- A lender, investor, buyer, or partner needs reliable reporting
- Your CPA explains the past but does not plan the next decision
Buy the right function
Bookkeeper, accountant, CPA, tax preparer, controller, or CFO?
| Role | Core job | Use when | Does not automatically mean |
|---|---|---|---|
| Bookkeeper | Transactions, reconciliations, close support | Records are late or unreliable | Tax strategy or assurance |
| Tax preparer | Prepare and file returns | Compliance is the defined need | Year-round planning |
| CPA | Licensed accounting and tax work | Judgment, filings, projections, or review matter | Industry expertise or proactive service |
| Controller | Own close, controls, and reporting | The accounting function needs leadership | Fundraising or strategic finance |
| CFO | Forecasting, capital, profitability, decisions | Management needs forward financial leadership | Daily bookkeeping execution |

Interview the process
15 questions to ask before hiring a CPA
Planning cadence
Which decisions trigger contact? When are projections updated? How are recommendations documented and implemented?
Business fluency
Which clients resemble us? How do books, payroll, entities, and owner returns move through one workflow?
Communication
What is the response standard? Which channel is secure? What happens during filing season or staff turnover?
Tax rigor
How are uncertain positions researched? Who monitors state issues and annual law changes?
Commercial terms
How are fees set? What causes a change order? What happens when the firm discovers cleanup work?
The revealing follow-up
Ask for one anonymized example of a recommendation the firm made before year-end, how it was implemented, and how the result was evaluated. Do not ask for a promised savings number.
Risk screen
Red flags that matter more than a polished sales call
- No named professional is accountable for review
- Sensitive documents are requested through ordinary email
- The firm recommends an entity before reviewing facts and economics
- Every prospect receives the same “strategy” list
- The fee is attractive but deliverables are undefined
- The team cannot describe its state or multi-entity process
- Planning begins after year-end
- The firm promises savings or audit-proof results
Geography
Local versus virtual CPA: use the real selection criteria
Driving distance can be valuable, but it is not evidence of expertise or responsiveness. Compare access to the right reviewer, security, industry fit, state capabilities, meeting cadence, and written follow-through.
| Question | Local advantage | Virtual advantage |
|---|---|---|
| Physical access | In-person meetings and local records | No travel; easier multi-location participation |
| Specialization | Local market familiarity | Larger nationwide specialist pool |
| State issues | Strong home-state familiarity | Multi-state systems and broader reach |
| Workflow | Can still be digital or paper-heavy | Usually designed around portals and cloud books |

Commercial clarity
Compare scope before comparing price
Separate return preparation, cleanup, monthly accounting, tax planning, notice response, payroll, and advisory. Ask which meetings, entities, states, forms, and implementation tasks are included. A lower proposal can be the better choice when the scope fits; a high fee is not proof of proactive work.

Transition without dropped balls
A practical CPA-switch checklist
| Stage | Collect or confirm | Owner |
|---|---|---|
| Before notice | Engagement scope, timing, fees, conflicts | Business owner and new CPA |
| Records | Returns, workpapers available to client, notices, elections, depreciation, basis, carryforwards | Prior firm and client |
| Access | Accounting, payroll, portals, agencies, payment systems | Client administrator |
| Deadlines | Returns, extensions, estimates, notices, elections, state renewals | New CPA |
| First 30 days | Open questions, cleanup, responsibility matrix, meeting cadence | New team |
