Accounting and Tax Practice Valuation: What CPA Firms Actually Sell For
Accounting and tax practices use a fundamentally different valuation convention than other small businesses — they are typically priced at 0.9× to 1.3× annual gross revenue rather than a multiple of SDE or EBITDA. This revenue multiple convention reflects the profession's unique client retention dynamics: a well-managed practice will retain 85–95% of clients through a transition, making the revenue base the most meaningful predictor of what the buyer will ultimately own.
Typical Valuation Range
| Multiple | Metric | Business profile |
|---|---|---|
| 0.9× – 1.0× | Annual Revenue | Tax-season-heavy practice, aging client base, heavy owner involvement, declining billings |
| 1.0× – 1.15× | Annual Revenue | Balanced mix of tax and accounting, stable client base, associate staff, good systems |
| 1.15× – 1.3× | Annual Revenue | Strong recurring bookkeeping/accounting revenue, advisory services, client average age under 55 |
Why Revenue, Not SDE?
The revenue multiple convention exists because accounting practices have predictable overhead structures and client retention is the dominant variable in long-term value. A buyer acquiring $500K in annual billings from a well-run practice can model expected client attrition at 10–15% through transition and forecast their net revenue with reasonable confidence. SDE-based multiples would vary too widely based on how the seller chose to staff and compensate themselves.
That said, buyers should still calculate the implied SDE multiple and verify it makes sense. A practice selling at 1.1× revenue on $500K in billings implies a purchase price of $550K. If SDE is $200K, that's a 2.75× SDE multiple — reasonable. If the seller is overstaffed and SDE is $80K, the same 1.1× revenue multiple represents a 6.9× SDE multiple that will be nearly impossible to service with SBA debt.
Service Mix Matters Significantly
Tax-only practices (1040 preparation, business tax returns) generate revenue in a highly seasonal January–April spike. Clients may switch if the transition isn't handled carefully, and the work is becoming increasingly automated.
Bookkeeping and accounting practices with monthly retainer clients have smoother, more predictable recurring revenue year-round. Monthly retainer clients are harder to switch away from (switching costs are higher), so retention through transition is typically better.
Advisory/CFO services — forward-looking planning, financial modeling, strategic advice — command the highest rates and the strongest client loyalty. A practice with 30%+ of revenue in advisory services trades at the top of the multiple range.
How Accounting Practice Deals Are Structured
Most accounting practice acquisitions use a client retention guarantee — the purchase price is paid in installments tied to actual revenue retained through the transition period (typically 12–24 months). This protects the buyer: if 20% of clients leave, the buyer pays 20% less than the headline purchase price. This structure is standard in the profession and both parties expect it.
Example: Valuing an Accounting Practice
A CPA practice with $420,000 annual revenue (40% tax preparation, 60% monthly bookkeeping retainers), 3 associate staff, solid technology infrastructure (QuickBooks Online, Karbon workflow management), and a client base with average age under 60 would likely trade at 1.1×–1.2× — a price of $462K–$504K, paid out over 24 months based on actual retained revenue.
