Step-by-Step Guide

1

Obtain your CPA license

Pass the CPA exam, complete experience requirements, and get licensed in your state if you plan to offer audit or attest services.

2

Choose your firm structure

Form an LLC, PLLC, or PC depending on your state’s rules for accounting firms; verify ownership restrictions for non-CPAs.

3

Purchase professional liability insurance

Buy errors and omissions (E&O) insurance ($1M+), which protects you if a client sues over a filing error or missed deadline.

4

Select tax and accounting software

Get certified in QuickBooks, Xero, or Sage; invest in professional tax preparation software like Drake, Lacerte, or ProConnect.

5

Define your service offerings

Choose between bookkeeping, tax preparation, payroll, audit, advisory, or a combination; price as hourly, fixed-fee, or monthly retainer.

6

Set up secure client portals

Implement encrypted document sharing and client communication tools to protect sensitive financial data and meet IRS security requirements.

7

Build your client base

Network with local businesses, join professional organizations, get referrals from attorneys and bankers, and invest in local SEO and Google Business.

8

Establish compliance and continuing education

Stay current with tax law changes, complete CPE requirements, and maintain your CPA license with regular renewal and ethics courses.
