Business-focused CPA firms generate highly predictable, recurring revenue — making them strong candidates for acquisition financing. Most deals combine an SBA 7(a) loan, a seller carry note, and a performance-based earnout tied to client retention, giving buyers manageable upfront equity requirements while protecting against post-close attrition risk.

Financing Options for CPA Firm (Business Tax Focus) Acquisitions

SBA 7(a) Loan

$500K–$3.5M, covering 70–80% of the total purchase pricePrime + 2.75%–3.5% (currently approximately 11–12%), 10-year term

The most common primary financing vehicle for CPA firm acquisitions. SBA 7(a) loans cover up to 90% of the purchase price, with the firm's recurring revenue and EBITDA used to demonstrate repayment capacity to participating lenders.

Pros

Low equity injection requirement of 10–15%, preserving buyer capital for working capital and post-close investments in technology or staffing
Lenders familiar with professional service cash flows accept CPA firm recurring revenue as strong collateral for underwriting
Fully amortizing structure provides predictable monthly payments aligned with the firm's consistent annual billing cycles

Cons

×Personal guarantee required from the buyer, creating full recourse exposure if client attrition causes revenue decline post-close
×Lengthy approval process of 60–90 days requires early lender engagement, which can complicate deal timelines with motivated sellers
×SBA lenders will scrutinize client concentration — a single client over 20% of revenue may trigger a loan condition or reduce approval amount

Seller Carry Note

$200K–$800K, representing 20–30% of total deal value5–7% interest, 5-year term with balloon or straight amortization

The seller finances 20–30% of the purchase price through a promissory note, subordinate to the SBA loan. Frequently structured with client retention milestones, aligning the seller's financial interest with a successful client transition over 12–24 months.

Pros

Signals seller confidence in the practice's transferability, which SBA lenders view favorably when evaluating the full capital stack
Retention-linked terms protect the buyer if key clients tied to the selling CPA leave within the first year post-close
Reduces buyer's required equity injection when combined with SBA financing, making deals accessible for first-time firm buyers

Cons

×Sellers approaching retirement often resist large carry notes, preferring cleaner all-cash exits funded by the buyer's SBA proceeds
×Negotiating retention thresholds — typically 80–90% of trailing revenue — can create post-close disputes over client attrition measurement
×SBA standby provisions may restrict seller note payments for 24 months, reducing the seller's immediate liquidity from the carry

Revenue-Based Earnout

$150K–$600K, representing 15–25% of purchase price paid over 24–36 monthsNo interest; structured as contingent purchase price tied to annual revenue retention benchmarks

A deferred payment structure where a portion of the purchase price is paid over 2–3 years based on actual client revenue retained post-close. Common in CPA firm deals where the seller's personal relationships drive a significant share of recurring billings.

Pros

Directly aligns seller incentive with client transition success, motivating genuine relationship handoffs to the buying CPA or team
Reduces buyer's day-one financial exposure in firms where the owner is the primary client contact and attrition risk is elevated
Flexible structure allows earnout thresholds to be tiered — paying more when retention exceeds 90% and scaling down to a floor at 80%

Cons

×Disputes over what counts as 'retained revenue' — especially for clients who reduce services or transition partially — can create post-close conflict
×Sellers nearing retirement are often resistant to earnouts lasting beyond 24 months, limiting the protection window for buyers
×Earnouts do not reduce the SBA loan principal, meaning buyers service full debt while earnout payments remain contingent and uncertain

Lender Tips for CPA Firm (Business Tax Focus) Acquisitions

1Engage SBA lenders who have closed professional service or CPA firm deals before — generalist lenders unfamiliar with revenue multiples on accounting practices often undervalue the business or add unnecessary conditions around intangible assets.
2Prepare a client concentration analysis showing no single client exceeds 15–20% of gross revenue before approaching lenders — high concentration is the fastest way to trigger a loan condition or receive a reduced approval amount.
3Request that your lender approve a seller transition consulting agreement as a deal cost rolled into the loan, covering the seller's 12–24 month paid transition — this protects client retention and is viewed favorably in SBA underwriting.
4Document staff credentials, non-solicitation agreements, and tenure for all licensed CPAs and EAs in the firm before underwriting begins — lenders will treat key-person dependency as a risk factor that can reduce loan proceeds or require additional collateral.

Frequently Asked Questions

Can I use an SBA loan to buy a CPA firm if I'm a first-time business owner?

Yes. SBA lenders will evaluate your CPA license, industry experience, and management background in lieu of prior ownership history. Ten-plus years of accounting experience typically satisfies lender requirements for professional service acquisitions.

How do lenders handle client concentration risk when financing a CPA firm purchase?

If a single client represents more than 15–20% of revenue, lenders may reduce the loan amount, require a larger seller note, or add a retention-based funding hold-back. Diversified client lists with no dominant relationship receive the most favorable terms.

What is a typical buyer equity injection for a CPA firm acquisition?

Most SBA-financed CPA firm deals require 10–15% equity from the buyer. On a $1.8M purchase, that translates to $180K–$270K in cash at close, with the balance covered by SBA debt and a seller carry note.

How does an earnout work alongside an SBA loan in a CPA firm deal?

The SBA loan covers the agreed base price at close. The earnout is a separate contingent payment made from post-close cash flow over 2–3 years based on client revenue retention, sitting outside the SBA structure entirely.
