How to Use an SBA Loan to Buy a Business-Focused CPA Firm
SBA 7(a) financing is one of the most accessible paths to acquiring an established accounting practice with recurring revenue. Here's exactly how it works for CPA firm deals in the $1M–$5M revenue range.

Business-focused CPA firms are among the most SBA-lender-friendly acquisition targets in the lower middle market. Their high percentage of recurring revenue from annual compliance engagements, predictable seasonal billing cycles, and multi-year client retention histories produce the kind of stable, documentable cash flow that SBA-preferred lenders look for when underwriting acquisition loans. A typical acquisition targets a firm generating $300K–$500K or more in seller's discretionary earnings (SDE) or EBITDA, with 80% or more of revenue derived from business entity clients — S-corps, C-corps, and partnerships — who require year-round service. SBA 7(a) loans are the dominant financing vehicle for these transactions, allowing qualified buyers to acquire a CPA practice with as little as 10% down while financing the balance over a 10-year term. Deal structures commonly layer an SBA 7(a) loan with a seller carry note and a revenue-based earnout tied to client retention thresholds, which directly addresses the client attrition risk that lenders scrutinize most closely in professional services acquisitions.
Down payment: For most CPA firm acquisitions using SBA 7(a) financing, buyers should plan to inject 10–20% of the total project cost as a down payment. On a $2M purchase price, that means $200K–$400K in verified buyer equity at closing. Lenders will require this equity to come from the buyer's own funds — not borrowed capital — and will verify the source through bank statements and a funds trail. When a seller carry note is included in the deal structure, it can count toward the buyer's equity injection under SBA rules, provided the seller note is on full standby for the first two years of the loan. A common structure for a $1.5M CPA firm acquisition might look like this: $1.2M SBA 7(a) loan, $150K buyer equity injection, and $150K seller note on standby — bringing total buyer out-of-pocket to 10% while giving the seller skin in the game around client retention outcomes.

10-year repayment term for business acquisitions; variable rate typically at Prime plus 2.25–2.75%; fully amortizing with no balloon payment
$5,000,000
Best for: Acquiring an established CPA firm with a documented earnings history, licensed staff in place, and a seller willing to remain for a structured 12–24 month transition period
SBA 7(a) Small Loan
10-year term for acquisitions; streamlined underwriting process with faster approval timelines than standard 7(a); same rate structure as standard 7(a)
$500,000
Best for: Smaller sole-practitioner CPA practices with purchase prices under $500K where the buyer seeks a faster close and simplified documentation process
SBA 504 Loan
10- or 20-year fixed-rate debenture for the CDC portion; best suited when hard assets are a significant component of the acquisition
$5,500,000 combined CDC and bank portion
Best for: CPA firm acquisitions that include the purchase of commercial real estate such as an office building or condo, where the firm owns its own space and it is included in the transaction price
Eligibility Requirements
- The buyer must be a licensed CPA or hold relevant credentials demonstrating the professional qualifications required to operate the firm and maintain client relationships post-close
- The acquiring entity must be a for-profit U.S.-based business meeting SBA small business size standards, typically fewer than $16.5M in net worth and less than $5.5M in average net income after taxes
- The CPA firm being acquired must generate sufficient cash flow — generally $300K or more in SDE or EBITDA — to service the SBA loan at a debt service coverage ratio of 1.25x or higher after accounting for buyer salary
- The business must have at least two to three years of tax returns and financial statements demonstrating consistent revenue, with any revenue declines clearly explained and supported by documentation
- Collateral will be required to the extent available, including business assets, goodwill, and potentially personal real estate if business assets do not fully secure the loan; SBA collateral requirements are flexible for goodwill-heavy acquisitions
- The buyer must inject a minimum of 10% equity — typically 10–20% of total project costs — from their own funds or a documented gift, with the full injection verified by the lender prior to closing
Step-by-Step Process
Assess Your Acquisition Criteria and Get Pre-Qualified
Before approaching sellers or brokers, define your target firm profile — revenue range, geography, service mix, and minimum SDE. Get a soft pre-qualification from one or two SBA-preferred lenders to understand your borrowing capacity based on your personal financials, credit score (aim for 680+), and available equity injection. Lenders will want to see your CPA license or credentials, personal tax returns for three years, a personal financial statement, and a resume demonstrating relevant industry experience operating or managing an accounting practice.
Identify Target CPA Firms and Sign an LOI
Source acquisition candidates through CPA practice brokers, the AICPA Succession Planning resources, regional accounting associations, or direct outreach to sole practitioners in your target market. Once you identify a fit, negotiate and execute a Letter of Intent (LOI) that outlines the purchase price, proposed deal structure including any earnout or seller note, exclusivity period, and transition expectations. The LOI is the foundation of your SBA loan application and should reflect a deal structure your lender has reviewed in advance.
Engage an SBA-Preferred Lender and Submit Your Loan Package
Select an SBA Preferred Lending Program (PLP) lender with demonstrated experience in professional services acquisitions — not just general small business lending. Submit a complete loan package including: three years of the target firm's business tax returns and financial statements, a detailed client revenue breakdown with retention history, staff roster with credentials and tenure, your personal financial statement and tax returns, a business plan projecting post-acquisition performance, and a purchase agreement or LOI. Lenders will stress-test cash flow to confirm 1.25x DSCR after your market-rate salary.
Complete Due Diligence on Client Concentration, Staff, and Technology
While the loan is in underwriting, conduct thorough due diligence on the firm's client base, staff, and operations. Request a revenue-per-client report for the trailing three years to identify concentration risk — flag any single client exceeding 15–20% of gross revenue immediately. Verify staff credentials, review non-solicitation agreements, and assess whether key employees are likely to remain post-close. Evaluate the technology stack: cloud-based firms on platforms like CCH Axcess, Thomson Reuters UltraTax, or Canopy are significantly more transferable than firms running legacy desktop software with locally stored client files.
Obtain a Business Valuation Acceptable to the SBA Lender
SBA rules require an independent business valuation for acquisitions where the purchase price exceeds $250,000 and goodwill exceeds $250,000 — which applies to virtually all CPA firm acquisitions in this size range. Engage a certified business appraiser with professional services experience. For CPA firms, valuations typically range from 0.9x to 1.4x gross revenue or a multiple of SDE depending on client mix, retention history, and staff depth. The appraised value sets the SBA-financeable ceiling; if your negotiated purchase price exceeds appraised value, the gap must be covered by buyer equity or a seller note.
Finalize Deal Structure, Close, and Begin Transition
Work with your attorney and lender to finalize the purchase agreement, seller note terms, earnout mechanics tied to client retention thresholds (typically 85–90% of trailing revenue retained at 12 and 24 months), and the seller's transition services agreement covering the 12–24 month post-close period. Coordinate SBA closing documentation with your lender. At closing, implement a client communication plan — ideally co-authored and co-delivered with the seller — to announce the transition professionally and maximize retention from day one.
Common Mistakes
- ✗Underestimating client concentration risk and accepting a deal where one or two clients represent more than 20% of revenue without a robust earnout that specifically protects against losing those anchor clients post-close
- ✗Choosing an SBA lender with no professional services acquisition experience, resulting in underwriting teams that misunderstand goodwill-heavy balance sheets, realization rates, and the legitimate billing economics of a CPA practice
- ✗Agreeing to a seller transition period shorter than 12 months — solo-practitioner CPAs carry deep personal relationships with business clients, and a rushed handoff is the single most reliable driver of post-close client attrition
- ✗Failing to verify that staff non-solicitation agreements are current, enforceable, and assignable to the new owner before closing, leaving the buyer exposed if key employees depart and approach firm clients independently
- ✗Skipping a detailed technology and data security audit, then discovering post-close that client files are stored on a local server, tax software licenses are non-transferable, or the firm's data practices create compliance exposure under state privacy regulations
Lender Tips
- Prioritize SBA Preferred Lending Program (PLP) lenders with a documented track record in professional services acquisitions — ask specifically how many accounting or CPA firm deals they have closed in the past two years before submitting your package
- Present your lender with a detailed client retention analysis alongside the standard financial package — showing 90%+ client retention over three to five years is the single most powerful underwriting signal for a recurring-revenue professional services business
- Structure the seller note on full standby for the first 24 months to satisfy SBA equity injection requirements and signal to the lender that the seller has meaningful financial incentive to actively support the client transition
- If the purchase price exceeds the appraised value due to premium goodwill in a high-retention firm, negotiate a seller note to cover the gap rather than asking the lender to stretch — SBA rules cap financing at appraised value, and experienced lenders will enforce this firmly
- Bring your SBA lender into the LOI stage before you sign — sharing the proposed deal structure, purchase price, and earnout mechanics early allows the lender to flag structural issues before you are contractually committed to terms that may not be financeable

Frequently Asked Questions
Can I use an SBA loan to buy a CPA firm if I am a first-time business buyer?
Yes. SBA 7(a) loans are accessible to first-time buyers provided you hold the required professional credentials — specifically a CPA license or EA designation — and can demonstrate relevant experience managing or operating within an accounting practice. Lenders will scrutinize your industry background closely because CPA firm goodwill is inseparable from professional credibility. A strong personal financial statement, a credit score above 680, and a well-prepared business plan projecting post-acquisition performance will significantly strengthen your application even without prior ownership experience.
How is a CPA firm valued for SBA loan purposes?
SBA lenders require an independent third-party business valuation for CPA firm acquisitions where goodwill exceeds $250,000. Valuations typically apply a revenue multiple of 0.9x to 1.4x gross revenue or a multiple of seller's discretionary earnings, adjusted for client concentration, staff depth, service mix, and retention history. Firms with 80%+ business entity clients, 90%+ trailing retention rates, and systematized workflows command multiples at the top of the range. The appraised value — not the negotiated price — determines the maximum SBA-financeable amount; any excess must be funded through buyer equity or a seller note.
What role does a seller note play in a CPA firm SBA acquisition?
A seller carry note — typically 20–30% of the purchase price — serves two functions in a CPA firm deal. First, it can satisfy part of the SBA equity injection requirement when placed on full standby for the first 24 months. Second, it aligns the seller's financial interests with successful client retention during the transition period, since the note is often structured with milestones tied to retaining 85–90% of trailing revenue. Sellers benefit because it allows them to achieve a higher effective purchase price than a discounted all-cash deal, while buyers benefit from reduced upfront capital requirements and a seller who is financially motivated to actively support the transition.
How does client concentration affect SBA loan approval for a CPA firm acquisition?
Client concentration is one of the most closely scrutinized risk factors in CPA firm SBA underwriting. If a single client represents more than 15–20% of gross revenue, lenders will flag this as a material risk and may require a larger buyer equity injection, a higher earnout threshold tied specifically to that client's retention, or a reduced loan-to-value ratio. In extreme cases — a single client representing 30% or more of revenue — the deal may not be financeable under standard SBA terms without significant structural mitigation. Buyers should request a revenue-per-client breakdown in their LOI and address concentration issues before submitting a loan package.
How long does it take to close an SBA-financed CPA firm acquisition?
From signed LOI to close, most SBA-financed CPA firm acquisitions take 90–120 days. The timeline breaks down roughly as follows: 30–45 days for the lender to process and approve the loan application, 2–3 weeks for the independent business valuation, 4–6 weeks for due diligence running concurrently with underwriting, and 3–4 weeks for legal documentation and closing coordination. Working with a PLP lender — who has delegated SBA authority and does not need to submit to the SBA for approval — can compress the underwriting phase by two to three weeks compared to a non-preferred lender.
Can an earnout structure coexist with SBA financing in a CPA firm deal?
Yes, and earnouts are actually common in SBA-financed CPA firm acquisitions precisely because they address the client attrition risk that lenders are most concerned about. A revenue-based earnout tied to retaining 85–90% of trailing revenue over 24–36 months reduces the effective purchase price if clients leave, protecting both the buyer's cash flow and the lender's collateral position. SBA rules allow earnout provisions as long as the total contingent payments are documented and the base purchase price — the non-contingent portion — is supportable by the business appraisal. Work with your SBA lender early to confirm how the earnout mechanics will be treated in the loan structure.
