Accounting Firm
Open a CPA or accounting practice with recurring tax and advisory clients.
TL;DR
An accounting firm serves individuals and small businesses with tax preparation, bookkeeping, payroll and advisory work, usually on a mix of annual engagements and monthly retainers. Using the CPA title requires licensure through your state board, though many firms employ non-CPA preparers and bookkeepers too. The strongest practices shift from seasonal tax work to recurring monthly services. Expect to spend about $2k–$20k to start, earn your first dollar in 1–3 months, and reach roughly $3k–$40k/mo after a year of steady work.
§ 01
Why an Accounting Firm business works now
Many accountants are retiring, leaving small businesses searching for a new provider. Cloud accounting and document tools let small firms serve clients remotely, which widens the market. Owners want proactive advice rather than a once-a-year tax filing.

How to start an Accounting Firm business
- 1
Confirm credentials and scope
Decide whether you will be a CPA, enrolled agent or non-credentialed preparer, and learn what your state board and the IRS allow for each. Only licensed CPAs may use that title.
- 2
Choose a client niche
Specialize in an industry such as trades, real estate investors, creators or medical practices so your advice and pricing are more specific.
- 3
Set up the firm and insure it
Form an entity, open a business bank account, obtain professional liability coverage and set up secure client data handling in line with applicable rules.
- 4
Build your technology stack
Choose tax preparation software, a document portal and practice management tools. Standardize intake with checklists and secure file sharing.
- 5
Write engagement letters and pricing
Offer fixed-fee packages for monthly bookkeeping, tax planning and returns, and use engagement letters that define scope and responsibilities.
- 6
Get your first clients
Ask your network for referrals, partner with attorneys, bankers and financial planners, and offer a short complimentary tax review to prospects.
- 7
Shift toward recurring revenue
Add monthly bookkeeping, payroll and quarterly planning meetings so income does not bunch up around filing deadlines.

Accounting Firm: FAQ
Do I need to be a CPA to start an accounting firm?
Not for all services. Bookkeeping and many tax preparation tasks do not require the CPA title, but using the CPA designation or issuing attest work does. Check your state board of accountancy.
How do accounting firms charge?
Many use fixed monthly fees for bookkeeping and advisory work and per-return fees for taxes. Hourly billing is still used for special projects.
What insurance does an accounting firm need?
Professional liability insurance is commonly carried, along with general liability and cyber coverage because you hold sensitive client data. A broker can explain options.
How do I handle tax season workload?
Limit the number of tax clients you take, set document deadlines, use checklists and add recurring work so revenue is not concentrated in a few months.
