Independent hiring guide

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

Where to look

How to find a good CPA for small business (and where to look)

Start with scope, then search where credentials are verifiable: the IRS preparer directory, your state CPA society, and referrals from the professionals who already see your numbers.

Searches for "find an accountant for small business" usually start with price. Start with scope instead. A bookkeeping quote, a business-return quote, and a planning quote are three different products, and the cheapest one is only a bargain if it is the product you need.

Three places produce candidates you can actually verify. The IRS Directory of Federal Tax Return Preparers lists CPAs, enrolled agents, attorneys, and other credentialed preparers with a current PTIN, searchable by ZIP code and credential type. State CPA society directories list licensed members, often by industry. Your banker, business attorney, or insurance agent sees which firms produce clean financials and timely filings; ask who they would use.

  • License status: confirm the CPA license is active with the state board of accountancy, not just claimed on a website
  • PTIN: anyone who prepares federal returns for pay must have one; the IRS directory lists only credentialed holders
  • Who does the work: a named professional should review your file, whatever the size of the firm
  • Representation rights: CPAs, enrolled agents, and attorneys can represent you before the IRS without limitation
  • Fit signals: clients that resemble you, cloud accounting, a secure portal, and a written engagement letter
  • Geography last: for most federal, state, and cloud-accounting work, a virtual CPA is as capable as a local one

Interview the process

Questions to ask an accountant for a small business: the 15 that matter

Scope and accountability

Who owns the relationship? Who reviews the work? What is included, excluded, and escalated?

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.

Local and virtual CPA considerations
QuestionLocal advantageVirtual advantage
Physical accessIn-person meetings and local recordsNo travel; easier multi-location participation
SpecializationLocal market familiarityLarger nationwide specialist pool
State issuesStrong home-state familiarityMulti-state systems and broader reach
WorkflowCan still be digital or paper-heavyUsually 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.
