For experienced CPAs eyeing ownership, acquiring an established business tax practice almost always beats building from scratch — but only if you know what you're buying.
For CPAs seeking ownership in the lower middle market, the buy-vs-build decision is rarely close. Business-focused CPA firms derive 80%+ of their value from long-standing client relationships, recurring annual engagements, and licensed staff who show up every tax season. These are assets you cannot manufacture overnight. Building a firm from zero means years of client acquisition, below-market billing rates to compete, and the very real risk of running out of runway before the practice reaches profitability. Acquiring an established practice — particularly one with $300K–$500K+ in SDE, a diversified business entity client base, and tenured staff — lets you step into predictable cash flow from day one. That said, acquisition carries its own risks: client attrition tied to the seller's personal relationships, staff retention uncertainty, and deal structures that often include revenue-based earnouts requiring careful management. The right choice depends on your capital position, your professional network, and your risk tolerance, but for most serious buyers, acquisition is the faster, lower-risk path to sustainable ownership.
Find CPA Firm (Business Tax Focus) Businesses to AcquireAcquiring an existing business-focused CPA firm gives you immediate access to recurring revenue from S-corp, C-corp, and partnership clients, a licensed staff roster, and an established reputation in the local market. With SBA 7(a) financing available and revenue multiples ranging from 0.9x to 1.4x gross revenue, acquisition is the most capital-efficient way to enter CPA firm ownership at scale.
Experienced CPAs with 10–20 years of client-facing tax experience who are ready for ownership, regional accounting firms executing geographic or service-line expansion, and PE-backed roll-up platforms adding practices to an existing portfolio.
Building a business-focused CPA firm from scratch gives you complete control over client selection, technology stack, pricing, and culture — but the economics are brutal in the early years. Without an inherited client base, you are competing for business tax clients against entrenched firms with decade-long relationships, lower staff acquisition costs, and established reputations. For most buyers with capital and experience, building is the slower, harder path.
A newly licensed CPA with minimal capital who wants to test the market solo, a niche specialist building an advisory-only model targeting a specific industry vertical, or an experienced practitioner with a large pre-existing referral network who can seed the client base immediately.
For the vast majority of experienced CPAs pursuing lower middle market ownership, acquisition is the superior path. Business-focused CPA firms sell at 0.9x–1.4x revenue — a relatively modest multiple for a business generating 80%+ recurring revenue with multi-decade client relationships and licensed staff in place. SBA financing makes these deals accessible with 10–20% equity injection, and the first tax season post-close delivers immediate cash flow that no startup can match. The risks are real — client attrition, seller transition management, earnout complexity — but they are manageable with proper due diligence, a structured 12–24 month seller transition, and revenue-based earnout protections. Building from scratch only makes sense if you have a compelling niche strategy, a pre-built referral pipeline, or no capital for acquisition — and even then, you should pursue acquisition as soon as the balance sheet allows. Time is the scarcest resource in a market where client relationships are measured in decades.
Do I have $90K–$420K in liquid equity to inject into an SBA-financed acquisition, or am I limited to the sub-$150K startup cost of building from scratch?
Do I have an existing referral network — attorneys, bankers, financial advisors — that could seed 20–30 business entity clients in year one if I build, or would I be starting cold?
Am I targeting a specific industry niche (real estate, manufacturing, e-commerce) where no established firm is for sale, making a build strategy the only viable path to that positioning?
How much personal runway do I have? Can I survive 3–5 years of sub-$200K income while building, or do I need to replace my current W-2 income within 12–18 months of leaving employment?
Have I completed due diligence on at least two or three acquisition targets in my target market, and am I confident I can identify and manage the client attrition and staff retention risks that come with a practice purchase?

Skip the build phase — acquire existing customers, revenue, and cash flow from day one.
Most business-focused CPA firms in the $1M–$3M revenue range sell at 0.9x–1.4x gross revenue, putting total acquisition cost between $900K and $4.2M. With SBA 7(a) financing, buyers typically inject 10–20% equity out of pocket ($90K–$420K), borrow 70–80% through an SBA loan, and structure the remaining gap as a seller carry note. Earnouts tied to client retention thresholds are common and effectively defer a portion of the purchase price by 2–3 years.
Realistically, 3–5 years for most practitioners starting from scratch. Business tax clients — S-corps, C-corps, partnerships — have extremely high switching costs and change accountants infrequently. Breaking into an established market without an inherited client base or a strong referral network is a multi-year effort. Most solo startup practices do not reach $300K–$400K in annual revenue until year three or four, and that threshold typically supports only a solo owner with limited staff capacity.
Yes. CPA firm acquisitions are among the most SBA-eligible professional service transactions in the lower middle market. SBA 7(a) loans support goodwill-heavy acquisitions where the primary asset is client relationships and staff, provided the deal meets SBA underwriting criteria including a minimum DSCR of 1.25x and the buyer demonstrating relevant industry experience. Seller notes are permitted as part of the capital stack and can bridge the gap between appraised value and purchase price.
Client attrition tied to the seller's personal relationships is the single biggest acquisition risk. In firms where the seller has been the primary — or only — client contact for decades, clients may follow the seller out the door regardless of non-compete agreements. Mitigating this requires a structured 12–24 month seller transition, revenue-based earnout provisions that incentivize the seller to facilitate introductions, and early staff engagement to identify which relationships have depth beyond the owner.
It can be, but compliance-only revenue faces meaningful long-term pressure from AI-driven tax software automation and commoditization. The strongest acquisition targets generate diversified revenue including payroll processing, bookkeeping, business advisory, and tax planning — services with higher billing rates and stronger client retention. A compliance-heavy firm is still acquirable at the right price, but factor in an advisory conversion strategy and evaluate whether the existing client base has the complexity and willingness to support higher-value engagements.
Structure the deal with a revenue-based earnout tying 20–30% of the purchase price to client retention thresholds — typically 80–90% of trailing revenue — measured over the first 2–3 years post-close. Require a 12–24 month seller transition with documented client introductions. Perform pre-close due diligence on client concentration, reviewing revenue per client over three trailing years to identify any single client exceeding 15–20% of gross revenue. Engage key staff early and assess whether they hold independent client relationships that will survive the seller's departure.
