How Much Is an Accounting Firm Worth?

How accounting practices are priced

The profession quotes a multiple of gross annual fees. The logic is that margins are broadly comparable across small firms, and that the typical buyer is another practice folding the work into an existing cost structure, so the seller’s expenses tell you little. Take the shorthand as a starting point and then do the earnings arithmetic anyway. Normalize SDE the same way you would for any business — profit plus owner compensation, plus personal expenses, plus one-time items — and sanity-check that the revenue multiple you are contemplating produces a sane multiple of earnings. A practice billing below market rates with an overstaffed back office can be worth well under 1x revenue; a lean, well-systematized one can justify more. The mechanics are covered in how to value a business and SDE vs. EBITDA.

Then read the structure, because it is doing most of the work. The standard deal pays over three to five years with each installment adjusted for revenue actually collected from the acquired client base. That retention clawback exists because in a professional practice the relationship frequently sits with the departing owner. As a buyer, treat a higher headline multiple with a long retention adjustment as cheaper — you are only paying for clients who stay. A seller demanding a high multiple and cash at close is asking you to underwrite their attrition risk for free. The broader acquisition process is in the buy an accounting firm playbook.

What moves the multiple

• Recurring vs. seasonal mix — Monthly bookkeeping, payroll, and advisory retainers are stickier and staff more evenly across the year. A book that is 90% individual returns filed in ten weeks earns a lower multiple and a harder hiring problem.
• Client concentration — A single client above roughly 10% of fees is a real risk in a firm this size. Get revenue by client for three years and look at the tail as well as the top.
• Realization and billing discipline — Compare billed hours to collected fees. Chronic write-downs mean the quoted revenue is aspirational, and a practice that has not raised rates in five years is carrying a repricing fight you will inherit.
• Staff continuity — The preparers and the office manager hold the client relationships and the institutional knowledge. Losing them costs more than losing the owner in most small firms.
• Owner transition commitment — A seller who stays through one full tax season and personally introduces the top clients materially improves retention, and that is worth paying for.
• Systems and workpapers — A firm on modern cloud software with organized, current workpapers transitions cleanly. A firm running on desktop software, paper files, and the owner’s memory transfers a fraction of its apparent value.

What pulls the price down

These are the findings that most often reprice a practice between the letter of intent and closing, or that should push you toward a longer retention-adjusted payout instead of cash at close.

• Revenue heavily concentrated in seasonal 1040 preparation with no recurring base.
• A handful of clients making up a large share of fees, especially if they came through the owner personally.
• Persistent write-downs between billed and collected, or billing rates far below market.
• Disorganized or missing workpapers, or engagement letters that are outdated or absent entirely.
• Key staff who have not been told about the sale and have no retention arrangement.
• Unresolved malpractice exposure, or no tail coverage arranged on the seller’s professional liability policy.
• An aging client base whose businesses are themselves winding down.

Worked example: a $700,000 tax and bookkeeping practice

A sole practitioner bills $700,000 a year: $420,000 of tax preparation and planning, $210,000 of monthly bookkeeping and payroll, and $70,000 of one-time advisory work. There are three staff. Normalized SDE, after adding back the owner’s compensation and personal expenses, is $245,000.

At a conventional 1.0x gross the asking price is $700,000 — a shade under 2.9x earnings, which is defensible for a business with recurring revenue and low capital needs. But the terms decide whether it is a good deal. Structured as 20% down with the balance paid over five years and adjusted annually for collected revenue from the transferred clients, the buyer is exposed only to clients who actually stay, and 1.0x is reasonable. Demanded as cash at close, the same book should trade closer to 0.8x — roughly $560,000 — because the buyer is now absorbing every departure alone.

Adjust from there on mix. Push the multiple up if the recurring share is well above the 30% here, if the seller commits to a full tax season of transition, and if workpapers are current in cloud software. Push it down if the advisory revenue is really one-time project work that will not repeat, if rates have been flat for years, or if the top five clients are a large share of fees. And model at least one downside scenario: what the payments look like if you lose 20% of the book in year one. If that scenario does not service the debt, the structure is wrong regardless of the multiple.

Before you rely on any of this

Ranges orient a conversation; they do not price a practice. Get three years of tax returns and the practice management system’s revenue-by-client and realization reports, and reconcile both to bank deposits. Confirm your state board’s ownership rules before you assume you can buy a licensed CPA firm at all, and confirm what happens to the firm name and any attest engagements. Verify that professional liability tail coverage is in place for the seller’s prior work, that engagement letters exist and are assignable, and that key staff are retained in writing. Then negotiate the retention adjustment carefully — how revenue is measured, what counts as a lost client, and what happens if the seller competes. Our due diligence checklist and how to verify business financials cover the process.
