What Lenders and Buyers Underwrite in a Tax Practice

A tax practice is one of the few professional businesses where the asset is a list of names. There is no inventory, almost no plant, and the equipment that matters fits in a laptop bag. That shapes every funding conversation. A bank cannot take a lien on a client relationship, and an investor cannot see a moat in a filing-season spreadsheet. So the plan has to do something the physical-asset businesses never need to do: prove that the relationships will repeat, and that they will still be there if the founder takes a fortnight off in August.

Lenders reading a tax practice plan tend to ask the same short list of questions, and the order matters. First, does the founder hold a credential that the IRS or HMRC recognises for representation work, because that is what separates a practice from a preparation stall. Second, how many of the planned clients already exist, in the form of a book being bought, a former employer's clients who have said yes in writing, or a pipeline of referral partners. Third, what share of revenue arrives outside January to April. A practice that earns 80% of its income in 14 weeks has a cash-flow problem that the P&L will hide, because the P&L only shows the annual total.

US funding routes that fit a tax practice

The SBA 7(a) programme is the default route for debt, with a ceiling of $5 million per borrower. The programme-wide average loan size was reported at about $443,000 for fiscal 2024, down from $538,000 the year before, while acquisition loans ran closer to $850,000 to $1.2 million because they bundle goodwill with equipment and working capital (E-Commerce Lending, 7(a) acquisition guide). A single-owner tax practice will usually sit far below that average, in the $40,000 to $350,000 band, with the larger figures reserved for practice purchases. For classification, tax preparation is NAICS 541213, and the SBA size standard for that code is $25 million in average annual receipts over five years (NAICS List, 541213). Almost every practice you will ever run falls inside it, so size eligibility is not the hurdle. The hurdles are equity injection and debt service coverage.

For a start-up with no purchased book, the SBA Microloan route (up to $50,000 through a community intermediary) often fits better than a full 7(a), because intermediaries accept thinner collateral and sometimes bundle small-business training. For founders leaving a firm with a verbal book of clients, a conventional term loan or a business line of credit from the bank that already holds the founder's personal accounts is frequently the fastest path. Revenue-based finance and merchant cash advances show up in the search results for this niche. They are poor fits: a seasonal business that takes a daily or weekly sweep in October, when income is lowest, is paying the most expensive money at the worst moment.

Buying a practice versus building one

Acquisition is the funding story most tax plans underplay. Sellers of small accounting and tax practices typically price at roughly 0.75 to 1.5 times annual gross recurring revenue, with the position inside that range driven by profit margin and client retention (Sofer Advisors, valuation beyond the 1x rule). The old rule of one times revenue still anchors deals between individual practitioners, while firms above about $2 million to $3 million in revenue increasingly attract private equity platforms that price on EBITDA, commonly in a 4x to 7x band (CT Acquisitions, accounting firm valuation). For the buyer of a $200,000 practice, that implies a purchase price somewhere between $150,000 and $300,000 before any earn-out or seller note.

The practical consequence for the plan: a bought practice arrives with revenue on day one, so the lender underwrites history rather than hope. A built practice arrives with zero. Both can work, but they need different plan structures. The build plan leans on a ramp table and a referral engine. The buy plan leans on retention assumptions: if you assume 85% of the seller's clients stay through the first filing season after the transition, and the seller's tax returns show where the other 15% sat, the lender can model a downside. Template sections for both are included in the downloads below.

What the debt service line looks like in practice

Take a founder buying a practice with $210,000 of recurring revenue for $190,000, funded with a $19,000 equity injection, a $142,500 bank loan and a $28,500 seller note. At a hypothetical 10-year amortisation on the bank loan the repayment is a little over $20,000 a year; the seller note, on a six-year schedule with interest-only for the first year, adds roughly another $5,000 in year one and $5,500 or so afterwards. The practice needs to generate enough owner earnings after a market salary to cover about $25,000 of debt service with a cushion of 25%, meaning roughly $31,000 of free cash. That is the number the plan's forecast must show in year one, and it is why lenders focus on retention and the seller's own financials rather than market-size slides. All loan figures in this example are Avvale modelling assumptions, not a quote.

If your plan is for a start-up rather than a purchase, replace the retention table with a referral-source table. Name the partners: the two or three small-business bankers, the payroll provider's local rep, the immigration or family-law firm that keeps needing a tax professional for expatriate and residency questions. Lenders discount a plan that says "word of mouth", and take seriously a plan that lists six introducers with a first-meeting date next to each.

The Tax Practice Market in 2026: Size, Structure and Pressure Points

US tax preparation services generated about $14.3 billion in 2025, a year in which industry revenue edged up just 0.1%, against a five-year compound growth rate of 2.7% (IBISWorld, Tax Preparation Services in the US). Global estimates run higher because they count more activity. One research house puts worldwide tax preparation services at roughly $34.9 billion for 2025 (Kentley Insights), though definitions vary between publishers, so treat the global number as an order of magnitude rather than a precise figure.

The headline growth rate of under 3% sounds uninspiring, and for the commodity end of the market it is. The interesting movement is under the surface: price and mix. Fee surveys show the average base fee for a Form 1040 with Schedules 1 to 3 rising from $162 in 2023 to $236 in 2025, with credential-linked gaps: about $280 at a CPA, $228 at an enrolled agent and $185 for a non-credentialed preparer (Accounting Today, what tax preparers charge). Surveys by the National Society of Accountants put itemised returns higher again, with returns that include a few schedules averaging in the several-hundred-dollar range (NSA 2024 Profit and Practice Report). Whatever source you favour, the direction is one way: preparers are raising prices, and most expect to do it again.

Who actually competes with a new practice

The competitive set has four layers, and each prices differently. At the bottom sit the franchised storefronts, H&R Block and Jackson Hewitt being the best known, plus seasonal pop-ups. They win on visibility, refund-advance products and walk-in convenience. Above them, the software-first services such as TurboTax Live and its assisted tiers compete for the simple W-2 filer who would rather pay $120 than book an appointment. In the middle are thousands of independent enrolled agents and CPAs, many operating from a spare room, who win on continuity. At the top are regional CPA firms that absorb the clients a small practice would love to graduate into: the owner with a dozen rental properties, a partnership and a state nexus problem.

A new practice does not beat any one of those layers head on. It picks a gap between them. The commonest gap is the self-employed client who is too complicated for software and too small for a regional firm: a freelance consultant with a home office and a retirement plan, a landlord with two out-of-state properties, a two-partner restaurant that has never closed its books before April. That client pays $450 to $1,500 for a return and, if retained, a monthly fee for bookkeeping oversight and quarterly estimates. The plan should name that client, size the local population using Census business counts, and show why the practice can serve them at a cost the franchise model cannot.

UK context for the same business

In the UK the picture is structurally different. Accounting services as a whole are valued at around £30 billion, split roughly 35% audit, 20% tax and 45% advisory (L.E.K. Consulting), and the number of accountancy, bookkeeping, auditing and tax consultancy enterprises fell from 43,720 to 39,975 between 2019 and 2025, a drop of 8.6% (Onrec, citing sector research). Fewer firms and an ageing principal population create succession deals, which is the same acquisition opportunity as in the US, with the added feature that Making Tax Digital for Income Tax is pushing self-employed and landlord clients toward agents who can handle quarterly digital submissions. Tax advice itself is unregulated in the UK, which means anyone can call themselves a tax adviser. Credibility therefore comes from voluntary membership of a body such as the Chartered Institute of Taxation or the Association of Taxation Technicians, and that is a selling point the plan should price in.

Across both markets, the regulatory pressure points are consistent. Cyber and data security rules have tightened for anyone holding client financial data. Clients expect a portal rather than email attachments. Staffing is tight, with experienced preparers scarce in the months where hiring has to happen. Each of these is a cost line in the model below, and each is a talking point in a lender meeting.

Launch Costs and Where the Money Goes

Because the credential is the main capital requirement and it is usually already in hand, tax practices are among the cheapest professional businesses to open. The cost question is really two questions. What does it take to open a home-based, solo practice for a founder who already holds an EA, CPA or equivalent? And what does it take to open a small office with two staff in place before the first return is filed? The first lands between about $19,000 and $51,000 once you fund working capital properly. The second lands between about $66,000 and $157,000. Every figure below is an Avvale planning estimate built from the vendor prices cited where stated; get local quotes before you submit anything to a lender.

Line by line, lean solo practice (US)

• Entity formation and state registration: $150 to $800. An LLC or S corporation filing in most states; a few states add an annual franchise fee that belongs in the forecast.
• Tax preparation software, first year: $2,195 to $3,641. Drake Tax Pro starts at $2,195 for a single-user licence (Drake pricing summary), while ProSeries tiers start around $2,605 for a 1040 package and $3,641 for the Essentials tier (Intuit ProSeries pricing). Lacerte runs a pay-per-return structure that starts at a $599 licence plus a per-return charge (Intuit Lacerte pricing), which lowers the entry price and raises the cost of a busy season.
• Practice management, portal and e-signature: $1,200 to $3,600. Tools such as TaxDome, Canopy, Karbon or SmartVault replace the email-attachment habit and generate the organiser, engagement letter and e-signature trail that Circular 230 diligence expects.
• Errors and omissions plus cyber cover: $1,200 to $3,500. Pricing rises with revenue and with the share of business returns.
• Hardware: $2,800 to $5,500. Two monitors, a document scanner with a feeder, a laptop, a locked cabinet or encrypted storage, and a secure printer.
• Website, brand and Google Business Profile: $2,500 to $7,500. Include a client intake form and a secure upload link; a plain brochure site converts worse than one that lets a prospect book a call.
• PTIN, continuing education and memberships: $600 to $1,800. The PTIN itself costs $18.75 for 2026 (TaxxSavage PTIN guide); the rest is course fees and an NAEA, AICPA or state society membership.
• Working capital: $8,000 to $25,000, equal to about four months of fixed costs plus the owner's drawing. This is the line that new owners shave, and the line that causes the problems in October.

That sums to roughly $18,600 at the floor and $51,300 at the ceiling. A founder with an existing laptop, a spare room and a book of clients will land near the floor; a founder who wants a branded website, a monitor setup and a six-month cash cushion will land above $35,000.

What changes with a small office and two staff

Moving from a spare room to an office adds four large items. A lease and fit-out (reception area, two preparer desks, a private meeting room with a document shredder) typically costs $12,000 to $30,000 including signage and cabling. Deposits and first-month rent add $3,000 to $8,000. Pre-opening payroll for two seasonal preparers, hired and trained in the three months before the filing season, runs $24,000 to $48,000. A launch marketing budget, covering direct mail to the surrounding postcodes, local sponsorship and Google Ads for a few months, adds $8,000 to $20,000. Add those to the lean build and the all-in range is $66,000 to $157,000. At the upper end the practice is financing the hire of people before the clients arrive, which is the single biggest reason an office-first plan fails.

A UK practice has a different cost profile. HMRC anti-money-laundering supervision, if you are a CIOT member, is currently £375 for the 2026/27 supervision year (CIOT, AML supervision registration). Professional indemnity cover for a sole practitioner often falls in the £600 to £2,500 range, practice software such as TaxCalc, IRIS or Xero Practice Manager adds £1,500 to £3,500 a year, and the UK all-in launch cost in a home-based model sits in the £12,000 to £35,000 band with working capital included. These are Avvale estimates; check quotes with a broker who specialises in accountants' cover.

Funding the gap between launch and first retainer

The tax calendar creates a cash trough. Preparation fees land between January and April, extension work in September and October, and retainer income builds slowly through the rest of the year. A realistic forecast shows the cash balance dipping lowest in late September, when nine months of fixed costs have been paid and only the extension work is coming in. Put the trough in the plan with a date and a number, then show what finances it: the working capital line above, a business line of credit sized at $15,000 to $30,000, or a delayed owner draw. Lenders rate a plan more highly when it names its own worst month.

Fee Ladder, Retainers and the Maths of a Mature Practice

Revenue in a tax practice is a ladder. The bottom rung is the single-return client, who pays once a year and may not return. The next rung is the client who also uses you for estimates and quarterly planning. Above that is the small business that pays a monthly retainer for bookkeeping oversight, payroll liaison and a year-end return package. At the top are the one-off, high-fee engagements: IRS notice resolution, offers in compromise, multi-state reconciliations, entity restructuring, sale-of-business planning. A practice's profitability is determined by how many clients climb the ladder and how quickly.

Industry sources report that a typical tax firm generates $300 to $600 per individual client in a year, while firms that concentrate on small businesses and advisory can generate $1,500 to $5,000 per client (Instead, tax advisory pricing guide). The spread between those two numbers is the commercial argument for a retainer-led model, and it is the central line in any plan you present to a lender.

Worked example: a solo enrolled agent with one seasonal preparer

The table below models a mature (year-three) practice run by one enrolled agent in a mid-sized US metro, supported by a seasonal preparer for roughly 800 hours a year. The fee levels sit inside the ranges cited above and are Avvale planning assumptions, not guaranteed outcomes.

Operating costs for the same practice add up to roughly $56,700: tax software $4,800, practice management and portal $2,600 inside that software line, errors and omissions cover $2,400, seasonal preparer wages of about $23,200 (800 hours at the BLS median of $26.40, plus payroll taxes), marketing $9,600, office or virtual-office rent $7,200, continuing education and memberships $2,100, card and bank fees $4,400, and professional fees and sundries $3,000. That leaves about $183,400 before the owner is paid, a margin of 76%. The 76% is misleading because it counts the founder's labour as free. Charge the practice a market salary of $95,000 for the owner, and what remains is $88,400, or 36.8% of revenue. That after-salary number is the one to show a lender, because it is the profit a buyer or a successor would actually receive.

Ramp: years one to three

Year-one revenue in the model is $128,000, about 53% of the mature level, built mostly from the first-year individual and self-employed book and a handful of retainer clients added from month five. Year two reaches $187,000 as retainers grow from 6 to 11 and business returns rise. Year three reaches the $240,000 shown above. Fixed costs sit around $29,100 a year before the seasonal preparer and rise in steps rather than smoothly, which is why lenders like to see the plan modelled monthly for year one. Break-even, defined as covering fixed costs plus a $95,000 owner salary, requires $124,100 of contribution, or about 468 average individual returns at $265, or an equivalent mix with higher-fee work. The plan should state that number plainly and then show the month in which the cumulative cash line crosses it.

Unit economics that distinguish a good practice

• Revenue per client: track it by cohort. A practice whose average client pays $410 is healthier than one at $290 even if it has fewer clients.
• Retention rate: 85% to 90% is a standard benchmark for a stable small practice; below 80% signals a service problem or a price-shopped book.
• Realisation rate: the share of standard fees actually collected after write-offs. Hourly-billing practices commonly lose 8% to 15% of billable value before invoicing.
• Seasonal concentration: the percentage of annual revenue booked between January and April. Moving this from 75% to 60% is worth more to a lender than any growth forecast.
• Pricing review cadence: reported surveys show 80% of firms planning fee increases heading into 2026, mostly in the 5% to 10% range. A fixed annual increase belongs in the model with a stated churn assumption.

Two further assumptions are worth stress testing in the plan. First, what happens if a software vendor raises per-return pricing by 15% in a year; the answer is usually small, below $700 on the model above, but it shows lenders that the cost base has been looked at. Second, what happens if returning clients fall by 10%. On the worked example that removes about $24,000 of revenue and reduces after-salary profit to roughly $64,000, which still covers $25,000 of loan repayments with room to spare. A forecast that survives a visible downside is more persuasive than one that shows only the upside.

Three Practice Models Compared Before You Pick One

"Tax consultancy" covers business models with very different capital needs, seasonality and exit values. A plan that tries to describe all of them reads as unfocused; a plan that picks one and explains why reads as a decision. The comparison below uses the same US assumptions as the worked example and should be adapted with local data.

The first model is the cheapest to start and the weakest to finance. Lenders read the seasonality figure and see a business that earns most of its income in four months and spends the other eight in a cash trough. The second model costs more to build and takes longer to reach profit, but the retainer base makes it financeable and sellable. The third works best for founders who already carry a reputation in the niche; the plan's task is to show the reputation as a source of leads, not just a credential.

The rule of thumb in the plan: if the founder has a book of clients arriving on day one, the retainer-led model is usually right. If the founder has none, a hybrid works: open as a seasonal shop for the first filing season to generate cash, and sign three to five retainer clients from that book in the first twelve months. State the target conversion rate from one-off to retained and defend it with the history of any comparable practice you know.

Named competitors and substitutes to address in the plan

US plans should name H&R Block, Jackson Hewitt and TurboTax Live, and explain what the founder offers that those three do not, which is almost always continuity, representation and advice outside of filing season. UK plans should name national online accountancy services such as Crunch and franchised networks such as TaxAssist Accountants, and explain the local, specialist or sector-focused service that sets the practice apart. If the target niche has a specialist competitor, such as an expat-tax boutique or a crypto-tax software vendor, name it and compare fees directly. A plan that cites competitors by name and quotes their published prices reads as researched; one that says "the market is fragmented" does not.

Credentials, Registrations and Insurance Across the US, UK and Canada

No tax practice plan is complete without a registrations table, because it shows lenders that the founder knows which licences are legally required and which are optional but commercially necessary. The three jurisdictions below cover the majority of English-language search demand for this business.

United States: federal requirements

• PTIN (Preparer Tax Identification Number): required for anyone who prepares or substantially assists in preparing a federal return for compensation. The 2026 fee is $18.75, and the PTIN must be renewed annually.
• EFIN (Electronic Filing Identification Number): required for a firm that files 11 or more federal returns electronically in a calendar year. It is free, issued per office location, and comes with a suitability check that includes fingerprinting for new applicants. Allow several weeks, and apply before the filing season, not during it (StartPermit, tax business guide).
• Annual Filing Season Program (AFSP): a voluntary IRS programme for non-credentialed preparers, requiring 18 hours of continuing education a year: a 6-hour Annual Federal Tax Refresher with a test, 10 hours of other federal tax topics and 2 hours of ethics. Completers appear in the IRS public directory and gain limited representation rights (IRS, Annual Filing Season Program).
• Circular 230: the rules governing practice before the IRS, including due diligence, fee conduct and conflicts of interest. Enrolled agents, CPAs and attorneys have unlimited representation rights; AFSP holders have limited rights; unenrolled preparers can represent only clients whose returns they prepared and signed.
• Written Information Security Plan: a requirement for tax preparers under the FTC Safeguards Rule, which also appears in IRS Publication 4557. A lender will ask whether you have one, and an insurer may too.

United States: state-level examples

State regimes vary widely. California requires non-CPA, non-EA, non-attorney preparers to register with the California Tax Education Council: 60 hours of qualifying education (45 federal, 15 California), a $5,000 surety bond, a PTIN and a registration fee of about $33 (CTEC, registered tax preparers). Oregon licenses its tax preparers and consultants through a state board, and Maryland and New York impose their own registration and education rules for preparers outside the CPA and EA categories. Because rules change, build a state-by-state checklist into your plan and date-stamp it: lenders in states with registration requirements will ask to see it.

United Kingdom

• AML supervision: anyone providing tax advice or accountancy services by way of business must be supervised for anti-money-laundering purposes under the 2017 Regulations. CIOT members register with CIOT, ATT members with ATT, and others default to HMRC. The CIOT fee for 2026/27 is £375 (CIOT; see also ATT AML registration).
• HMRC agent authorisation: before dealing with HMRC for a client, you need either a signed form 64-8 or digital authorisation through the agent services account. Each new client adds an authorisation to the admin workload.
• Professional indemnity insurance: not required by statute for unregulated tax advisers but required by CIOT as a condition of practising certificates and demanded by most clients. The CIOT's guidance on setting up in practice is a reasonable checklist (CIOT, setting up in practice).
• ICO registration: data-protection fee payable to the Information Commissioner's Office, because you will process client personal data. Check the current tier.
• Voluntary designations: CTA (Chartered Tax Adviser) with CIOT, ATT (Taxation Technician), or ICAEW and ACCA memberships. None is a legal prerequisite, and all matter for credibility.

Canada

Canadian tax preparers who are paid to prepare personal income tax returns must register for EFILE with the Canada Revenue Agency and use certified software. Applicants must be Canadian residents with a social insurance number and at least 18 years old, and the application includes a suitability screening. Processing has taken up to 30 business days, and renewal is annual (Government of Canada, EFILE registration announcement). Mandatory electronic filing originally applied to preparers handling more than 10 returns a year, and Knowledge Bureau reported the threshold dropping to six or more for the 2025 season (Knowledge Bureau). Check the current rule before you plan volumes.

Insurance and data protection as a plan section

Treat insurance and security as a funded line, not a footnote. An errors and omissions policy sits between $1,200 and $3,500 a year for a solo US practice, with higher premiums for a heavy business-return mix. Cyber cover matters because the practice holds Social Security numbers, bank details and prior-year returns in one place. A lender who asks for a security plan is not being fussy: tax preparers are a recurring target for identity thieves, and the IRS and state revenue departments publicly warn practices about it.

Five Mistakes That Sink New Tax Practices

1. Planning for filing season and forgetting the other 40 weeks

Founders copy the revenue pattern of a franchise and then discover that, outside four months, the phone is quiet. A plan that models only peak months overstates annual revenue and understates working capital. Put the retainer line, the extension work and the planning sessions in the model before you put them in the marketing plan.

2. Pricing at the bottom of the local range to win first-year volume

A $120 return wins clients who will leave for a $99 return. Surveys show that average fees are rising and most firms intend to raise them again, so a founder who enters low faces a double correction: a price increase that triggers churn, and a client base that never valued the service. Price near the local median for your credential, and win on responsiveness.

3. Under-budgeting software and security

Tax software, a client portal and e-signature tools together cost $3,400 to $7,200 in year one. Founders who skip the portal handle sensitive documents by email, which is slow for clients and a liability for the practice. A security incident costs more than five years of software subscriptions.

4. Ignoring state and local registration

The federal checklist is short. State checklists are not. A preparer who moves to California without CTEC registration, or opens in a state with its own licensing board, can face penalties that wipe out a season's profit. The plan should include a dated, source-linked registration table for every state in which clients will be served.

5. Building a practice that cannot be sold

If every client relationship depends on the founder, the practice has no exit value. At a 0.75x to 1.5x revenue multiple, the difference between a practice that transfers cleanly and one that does not is worth tens of thousands of dollars. Plan from day one for a second credentialed professional, written engagement letters, documented workpapers and a client communication cadence that the business, not the founder, owns.
