Buying an existing tax practice hands you a client base, recurring revenue, and a working operation from day one, but the shortcut only pays off if you get the transaction right. Learning how to buy a tax practice means working through a sequence: identifying a target, valuing it, signing a letter of intent, conducting due diligence, choosing a deal structure, financing the purchase, closing with the right legal and insurance protections, and managing the client handoff that ultimately determines whether the acquisition succeeds or fails.
Finding the Right Practice
Specialized accounting practice brokers keep confidential listings that don’t appear on general business-for-sale platforms. They pre-screen sellers and handle introductions, but they typically represent the seller, so understand the incentive structure before you rely on their guidance. Direct outreach to sole practitioners nearing retirement works well as a second channel. State CPA societies and professional associations sometimes facilitate succession planning or host confidential forums for buyers and sellers.
Screen aggressively before spending time on any single opportunity:
- Geographic fit. A tax practice’s value sits in its local client relationships. Buying where you already operate, or plan to, makes the transition far smoother.
- Service mix. Recurring compliance work — annual returns, bookkeeping — produces more predictable cash flow than one-time advisory projects.
- Revenue composition. Average fee per client tells you more than gross revenue. A practice billing $3,000 per client is a different business from one billing $300, even at the same top line.
- Client concentration. If a single client represents more than 10–15% of revenue, losing that client after closing can wreck your projections. Concentration should either lower the price or trigger an earn-out.
The target also needs enough revenue to justify legal and accounting costs. A $75,000 practice takes nearly the same due diligence work as a $500,000 practice, so very small firms usually aren’t worth the friction unless priced accordingly.
Valuing the Practice
Tax practices are most commonly valued as a multiple of gross revenue. Small firms under $1 million in revenue generally trade between 0.8x and 1.2x. Mid-sized firms in the $1–5 million range command 1.0x to 1.5x, with the premium going to practices that have strong advisory work, specialized niches, or unusually high retention. Those ranges are starting points, not formulas. The real price depends on what the financials reveal under scrutiny.
Seller Discretionary Earnings
For owner-operated practices, Seller Discretionary Earnings (SDE) is the meaningful metric. SDE represents the total economic benefit available to one working owner. Start with net income and add back the owner’s salary, personal expenses run through the business, interest, depreciation, amortization, and any non-recurring costs. Common add-backs in tax practices include above-market owner compensation, personal vehicle expenses, travel that mixed business with personal use, and one-time costs like an office relocation or a legal dispute.
Add-backs are where valuations get manipulated, intentionally or not. Every expense the seller adds back to inflate SDE needs independent evaluation. A country club membership listed as “client entertainment” might genuinely generate business or might be purely personal. Stress-test every add-back rather than accepting the seller’s numbers.
EBITDA for Larger Practices
For larger practices with professional management that doesn’t depend on the owner, EBITDA multiples fit better. Small firms typically sell in the 2x–4x EBITDA range; mid-sized firms reach 4x–6x. The shift from SDE to EBITDA reflects a business that can function without the owner at the helm, which is a fundamentally different asset than a practice where the owner is the practice.
Whichever metric you use, the final multiple is sensitive to client retention history, the mix of compliance and advisory work, staff stability, and how transferable the client relationships are. A practice where the owner personally handles every major client will retain fewer of those clients than one where staff accountants manage day-to-day relationships.
Signing a Letter of Intent
Before committing to full due diligence, sign a letter of intent (LOI). The LOI sets out the proposed structure, purchase price, payment terms, and key conditions. Most of its provisions are non-binding; its real purpose is aligning expectations before either side spends serious money on lawyers and accountants.
A few provisions should be binding. An exclusivity period gives you sole negotiating rights for 60–90 days. A confidentiality obligation protects the seller’s business information. And you should settle who pays for tail coverage on the seller’s professional liability insurance. Handling tail coverage in the LOI keeps it from becoming a last-minute deal breaker at closing. In most practice acquisitions the cost is either split or assigned explicitly to one party.
The LOI should also specify whether you’re buying assets or equity, the expected timeline, and any conditions you consider essential, like a non-compete or a seller transition period. None of it is final, but walking into due diligence without an LOI means every term is still open for renegotiation at the worst possible moment.
Financial and Operational Due Diligence
Due diligence is where you verify whether the practice is actually worth what the valuation says. Reconcile the revenue figures used in the valuation against tax returns and bank statements for at least three years. For a sole proprietor, that means Schedule C on personal returns. For a corporation or partnership, review the entity returns. Bank deposits should match reported revenue. Gaps mean either unreported income (a different kind of problem) or overstated revenue on the seller’s side of the negotiation.
Scrutinize every SDE add-back against documentation. If the seller claims a $40,000 add-back for above-market compensation, you need comparable salary data to confirm what “market” actually looks like. If they add back a $15,000 legal expense as “non-recurring,” ask what the dispute was and whether it’s truly resolved.
Client Base Analysis
Go beyond client count. Pull the client list and analyze average fee per client, service distribution, retention over the past three to five years, and how revenue is concentrated. Industry surveys suggest the average practice loses 5–10% of clients annually to normal attrition like relocation, death, and divorce. If the seller’s attrition runs meaningfully higher, something is driving clients away, and that something won’t disappear when you take over.
Look at tenure too. A practice where most clients have been around ten or more years signals deep relationships, but those relationships may be with the departing owner rather than with the firm. A practice where half the clients are new in the last two years may indicate recent growth or recent churn from a prior problem.
Operations, Technology, and Staff
Review the technology stack: tax preparation software, practice management, document storage, cybersecurity. Outdated systems aren’t deal-killers, but they’re a real cost that belongs in your post-acquisition budget. Verify that software licenses are transferable or plan for replacements.
Staff assessment matters more than most buyers realize. If a single non-owner employee handles the bulk of client relationships, that person’s departure would be nearly as damaging as losing the seller. Get a clear picture of each employee’s role, compensation, and any existing employment agreements. For key staff, plan to negotiate retention bonuses or new employment contracts before closing.
Choosing a Deal Structure
Structure drives your tax bill, your liability exposure, and your ability to deduct the purchase price over time. The two options are an asset purchase and a stock (or equity interest) purchase.
Asset Purchase
Most buyers prefer an asset purchase because it provides a stepped-up tax basis in everything acquired. That step-up lets you amortize the cost of intangible assets, including goodwill and the customer list, over 15 years under Internal Revenue Code Section 197.1Office of the Law Revision Counsel. 26 USC 197 Amortization of Goodwill and Certain Other Intangibles In a tax practice, the customer list and goodwill make up the vast majority of the purchase price, so the amortization deduction is substantial. Over 15 years, you’re deducting essentially the entire intangibles portion of the price.
An asset purchase also lets you avoid the seller’s unknown liabilities. You choose which assets to buy and which obligations to take on. The seller retains the entity and its historical baggage.
Stock Purchase
A stock purchase is simpler mechanically. You buy the seller’s ownership interest and the entity continues as before. Sellers often prefer this because they can treat the entire gain as capital gain. As the buyer, though, you inherit everything: every undisclosed liability, every unresolved client dispute, every potential regulatory issue. You also lose the basis step-up, so you can’t amortize the purchase price. For most tax practice acquisitions, the asset purchase is the better structure for the buyer.
Purchase Price Allocation and Form 8594
In an asset purchase, both parties must agree on how to allocate the purchase price across seven asset classes and report that allocation on IRS Form 8594.2Internal Revenue Service. Instructions for Form 8594 – Asset Acquisition Statement Under Section 1060 The allocation is binding on both parties under Section 1060.3Office of the Law Revision Counsel. 26 USC 1060 Special Allocation Rules for Certain Asset Acquisitions
For a tax practice, the allocation typically flows into three classes:
- Class V. Tangible assets like furniture, computers, and equipment.
- Class VI. Section 197 intangibles other than goodwill — the customer list, workforce in place, covenants not to compete, and business books and records.
- Class VII. Goodwill and going concern value.
The buyer generally wants more allocated to Class V assets, which can be depreciated faster, and to the non-compete. The seller wants more in goodwill to support capital gains treatment. These competing interests produce one of the most negotiated aspects of any deal, and getting the allocation wrong creates real tax exposure on both sides.
Financing the Purchase
Most buyers combine SBA-backed lending, seller financing, and personal equity.
SBA 7(a) Loans
The SBA 7(a) loan program is the most common financing vehicle for practice acquisitions, with a maximum loan amount of $5 million. The SBA doesn’t lend directly; it guarantees a portion of the loan made by a participating lender. For loans of $150,000 or less, the SBA guarantees 85%. Above $150,000, the guarantee drops to 75%.4U.S. Small Business Administration. 7(a) Loans
The SBA charges a guarantee fee that scales with loan size and maturity. Interest rates are capped at a spread over the base rate, with the maximum spread narrowing as the loan amount rises. For acquisitions of $500,000 or less, the SBA does not require a specific equity injection; the lender applies its own standards. For acquisitions above $500,000 involving a complete change of ownership, the SBA requires at least a 10% equity injection.5U.S. Small Business Administration. Business Loan Program Improvements
Seller Financing
Seller financing is common and often signals that the seller believes in the practice’s continued viability. In a typical arrangement, the buyer makes a down payment and the seller carries a promissory note for the balance, paid over several years with interest. Lenders like seller notes because they keep the seller financially invested in a smooth transition. Terms are fully negotiable; interest on the seller note usually sits somewhere between commercial rates and a small premium reflecting the seller’s subordinated position behind bank debt.
Earn-Out Provisions
An earn-out ties part of the purchase price to post-closing performance, usually measured by client retention. It’s one of the strongest risk-mitigation tools available to a buyer. If 20% of clients leave in the first year, the earn-out adjusts the total price downward to reflect the reduced value of what you actually received.
Structure earn-outs carefully. The IRS looks at whether earn-out payments tied to a seller’s continued employment look more like compensation than deferred purchase price. If the seller stays on and the earn-out is contingent on that continued employment, those payments may be recharacterized as ordinary income for the seller and deductible compensation for the buyer, rather than capital gain and non-deductible purchase price. Both sides need to understand the tax characterization before signing.
Professional Liability and Insurance
Insurance is the area most buyers underestimate, and it produces some of the ugliest surprises. Errors the prior owner made on client returns can surface months or years later as malpractice claims. How you handle insurance determines whether those claims land on the seller’s policy or your balance sheet.
Tail Coverage
Professional liability insurance for tax practitioners is almost always written on a claims-made basis, meaning it covers claims filed while the policy is active regardless of when the error occurred. When the seller cancels their policy at closing, claims filed after that date are uncovered unless the seller buys an extended reporting period, commonly called tail coverage. Tail coverage extends the reporting window for claims arising from work done during the original policy period. It can last one to three years, with some policies offering unlimited tail coverage. Settle who pays before closing, ideally in the LOI, so the cost is priced into the transaction.
Your Own E&O Policy
You’ll need your own errors and omissions policy effective on the closing date. Typical E&O policies for small tax practices run from several hundred to a couple thousand dollars annually, depending on revenue, services, and claims history. Standard policies exclude intentional fraud, criminal acts, services outside your core tax practice such as legal consulting, and cyber liability. Because every tax practice handles sensitive financial data, consider a separate cyber liability policy; most E&O policies don’t cover data breaches.
The Purchase Agreement and Closing
The Purchase and Sale Agreement (PSA) turns your negotiated terms into binding legal obligations. Several provisions deserve particular attention in a tax practice deal.
Representations, Warranties, and Indemnification
The seller should represent that the financial statements are accurate, that there are no undisclosed liabilities, that the client list is current, and that the practice is in compliance with applicable regulations. Indemnification clauses obligate the seller to compensate you if any of those representations turn out to be false. Set a survival period, typically 18 to 24 months after closing, and negotiate a cap on total indemnification exposure, usually a percentage of the purchase price.
Non-Compete Agreements
A non-compete is essential. Without one, nothing stops the seller from opening a new office across the street and calling every client on the list you just paid for. Non-competes signed in connection with the sale of a business are treated differently from employment non-competes and are generally enforceable when reasonable in geographic scope and duration. A typical non-compete in a tax practice sale covers a 15–25 mile radius for three to five years. The value allocated to the non-compete on Form 8594 is amortizable over 15 years as a Section 197 intangible.1Office of the Law Revision Counsel. 26 USC 197 Amortization of Goodwill and Certain Other Intangibles
Licensing and Regulatory Requirements
Confirm your own credentials are in order. Anyone preparing federal tax returns for compensation must hold a valid Preparer Tax Identification Number (PTIN), which costs $18.75 to obtain or renew for 2026.6Internal Revenue Service. PTIN Requirements for Tax Return Preparers If the practice performs work that requires CPA licensure, such as audits, reviews, or attestation services, you’ll need to hold or employ someone with the appropriate license. Notify your state board of accountancy about the ownership change, since most states require updated firm registration. Filing fees vary by state.
Closing and Post-Closing Filings
At closing, financing documents are signed, funds transfer, and the client list is formally conveyed. In an asset purchase, both parties file IRS Form 8594 with their tax returns for the year of the sale, reporting the agreed purchase price allocation. If the allocation is later adjusted, for example because of an earn-out payment, an amended Form 8594 is required for the year of the adjustment.2Internal Revenue Service. Instructions for Form 8594 – Asset Acquisition Statement Under Section 1060
Retain all acquisition records for as long as they may be relevant to your tax filings. The IRS general record-retention guideline is three years from the date a return is filed, but that extends to six years if income is underreported by more than 25%, and to seven years for claims involving bad debt or worthless securities.7Internal Revenue Service. Topic No. 305 Recordkeeping Practically, keep all deal documents, the PSA, the Form 8594, and supporting financials indefinitely. You’ll need them to calculate basis and amortization deductions for years to come.
Managing the Client Transition
Everything before this point is worthless if the clients leave. Industry data suggests the average practice sale retains 75–80% of clients, so a meaningful minority walks away even in a successful transition. The gap between keeping 90% and keeping 65% usually comes down to how the first few months are handled.
The Seller’s Introduction
The single most important step is having the seller personally introduce you to clients. A joint letter from the seller explaining the transition, endorsing your qualifications, and reassuring clients that the seller chose you specifically after a careful search carries far more weight than anything you could send on your own. For top revenue-generating clients, a personal phone call or in-person meeting with both you and the seller is worth the time. The seller should explain why they’re transitioning — retirement, health, a new chapter — and confirm they’ll be available during the transition period. Clients who hear directly from the person they trust that this was a deliberate decision are far less likely to shop for a new preparer.
Minimizing Disruption
During the first year, and especially the first tax season, resist the urge to change everything. Keep the office location open at least through the first busy season if clients are used to visiting in person. Maintain the same phone number, the same filing procedures, and the same fee structure. Changes to any of those signal instability and give clients a reason to reconsider.
The seller should be available during the transition — ideally a few months at minimum, longer for complex practices — to answer questions, explain firm procedures, and smooth over friction. Write the transition commitment into the purchase agreement with clear expectations on hours and duration. Address the seller’s billable time during the transition explicitly so it doesn’t become a source of post-closing conflict.
Building Your Own Relationships
After the initial transition, the goal shifts from preserving the seller’s relationships to building your own. Schedule introductory calls with every client within the first 90 days. Ask about their goals, pain points, and services they wish they had. Clients who feel personally known by the new owner are dramatically less likely to leave than clients who feel like they were sold as part of a package.
