How to Buy a Small Business: Financial Guide 2026

Buying an existing business is often faster to profitability than building from scratch — you're acquiring proven cash flows, a customer base, systems, and employees. But the financial and tax decisions made during acquisition have long-lasting consequences. This guide covers SBA financing, how to value what you're buying, deal structure from the buyer's perspective, and how to optimize the acquired business financially from day one.

Step 1: How much can you finance?

Before evaluating specific targets, establish your financing capacity. Business acquisition financing typically takes one of three forms:

• SBA 7(a) loan. The most common route for acquisitions under $5M. The SBA guarantees 75–85% of the loan, enabling lenders to offer better terms than they would on unsecured acquisition debt. In May 2026 the SBA doubled the cumulative 7(a) + 504 limit to $10 million, expanding capacity for serial acquirers.¹
• Conventional bank financing. Available for creditworthy borrowers or real-estate-heavy deals. Typically requires 20–30% down with more conservative underwriting than SBA.
• Seller financing. The seller accepts part of the purchase price as a promissory note. Often used alongside SBA financing — the seller note goes on "full standby" for the life of the SBA loan, meaning no payments during that period. This lets buyers satisfy the SBA's 10% equity injection with 5% cash + 5% seller note.

Step 2: SBA 7(a) financing mechanics

SBA 7(a) loans are originated by SBA-approved lenders — banks, credit unions, and non-bank lenders — with the SBA providing a government guarantee against default. Key terms for buyers:

• Minimum 10% equity injection for complete change-of-ownership acquisitions. Half can come from a seller note on full standby. The buyer must contribute at least 5% in cash.
• Rate caps set by SBA. Variable rates are capped at Prime + 2.25% to Prime + 4.75%, depending on loan size and term. With Prime at 6.75% in June 2026, that's roughly 9–11.5% APR. Fixed-rate caps run slightly higher.²
• FY 2026 upfront guarantee fees: 2% for loans ≤$150K; 3% for $150K–$700K; 3.5% on the first $1M of the guaranteed portion + 3.75% on the guaranteed portion above $1M, for loans over $700K.³
• Personal guarantee required. Any owner with 20%+ of the acquiring entity must personally guarantee the SBA loan.
• SBA manufacturer incentive. Manufacturing businesses acquiring up to $950K in SBA-financed equipment qualify for a 0% upfront fee in FY 2026.

SBA 7(a) can fund the purchase price, working capital, equipment, and real estate in a single loan. For service businesses where the purchase price is mostly goodwill and intangibles, the standard term is 10 years. If the deal includes commercial real estate, the real estate portion can carry a 25-year term.

Step 3: Valuing the target — what you're actually paying for

Small business valuation uses two primary earnings benchmarks. Understanding which applies to your target prevents you from overpaying.

Industry multiple ranges (EBITDA):

• SaaS / software: 5–12× (recurring ARR is the key driver)
• Healthcare practices: 4–8× (payer mix, EBITDA margin, referral dependency)
• Manufacturing: 3.5–6× (capital intensity, customer concentration)
• Professional services: 3–6× (client portability, owner dependence)
• Retail / restaurant: 1.5–3× (lease risk, thin margins, location dependency)

These are ranges, not guarantees. The actual multiple depends on growth trajectory, recurring revenue percentage, customer concentration, and how dependent the business is on the exiting owner. See the full business valuation guide for SDE calculation methodology and add-back analysis.

Quality of Earnings (QoE) analysis — not optional above $500K

Before signing an LOI on any acquisition over $500K, engage an independent M&A financial advisor to recast the financials in a Quality of Earnings analysis. A QoE typically costs $15–50K depending on complexity. It will:

• Identify which seller add-backs are legitimate vs aggressive
• Surface revenue recognition issues (deferred revenue, pull-forward, one-time items booked as recurring)
• Stress-test the normalized EBITDA you're paying a multiple on
• Flag customer concentration, contract terms, and retention risk

This is not the seller's CPA's work — the seller's CPA prepared returns to minimize taxes, not to present business performance for a buyer. You need your own independent analysis.

Working capital peg

The purchase agreement will include a target working capital level at closing. If actual working capital at close falls below target, the seller owes you a post-close true-up. If it's above target, you owe the seller. Negotiate the target carefully and model your working capital need separately from the acquisition price — you may need cash at close beyond the down payment to fund initial operations.

Step 4: Deal structure — the buyer's tax priorities

Deal structure affects your tax position for years after acquisition. Buyers and sellers have directly opposite preferences.

The §338(h)(10) election

When a buyer acquires 80% or more of a corporation's stock within a 12-month window — a "qualified stock purchase" (QSP) — the buyer and seller can jointly elect under IRC §338(h)(10) to treat the transaction as an asset purchase for tax purposes, while legal title transfers as a stock sale.⁴

Why buyers prefer it:

• Full step-up in tax basis. Instead of inheriting the seller's depreciated asset basis, the buyer's basis equals the purchase price allocated across all assets. A business sold for $3M with $300K of net book value generates a $2.7M basis step-up the buyer benefits from going forward.
• §197 intangible amortization. Goodwill, customer relationships, non-compete agreements, and trade names are amortized straight-line over 15 years. On a $3M acquisition where goodwill is $1.8M, that's $120,000/year of pre-tax deductions for 15 years — roughly $44,000/year in tax savings at a 37% combined rate.
• Fresh depreciation on hard assets. Equipment, vehicles, and furniture are re-based to their purchase price allocation. Combined with OBBBA 100% bonus depreciation (for qualifying property placed in service after January 19, 2025), you may be able to expense significant equipment value in year one.
• No inherited tax liabilities from the target entity's pre-acquisition history.

The trade-off: the seller is taxed as if they sold assets — ordinary income on depreciation recapture (§1245), capital gains on goodwill and intangibles. For sellers whose primary asset is goodwill (service businesses), the difference from a plain stock sale can be modest. For sellers with significant §1245 recapture, it's material. Buyers typically compensate with a "gross-up" — a higher purchase price to make the seller whole for the additional tax cost.

Purchase price allocation (§1060, Form 8594)

In an asset sale or §338(h)(10) deal, both parties must allocate the purchase price across seven asset classes under IRC §1060. The allocation drives your depreciation and amortization schedule. Buyers prefer heavier allocation to depreciable assets (§197 intangibles, equipment) and away from non-depreciable items (land, non-competes shorter than 15 years). Sellers have opposite incentives on recapture. Negotiate the allocation — both parties file Form 8594 and the IRS matches them.

Step 5: Due diligence — financial red flags

These issues most frequently kill deals or force material price reductions:

• Customer concentration above 20%. A single customer representing 30%+ of revenue typically triggers an earnout structure — the seller doesn't receive full proceeds unless that customer stays post-close. If one customer is 50%+ of revenue, evaluate whether you're buying a business or a customer relationship.
• Cash-basis financials. Cash-basis accounting makes revenue appear lumpy and timing-dependent. Request 3+ years of accrual-basis books. If the seller only has cash-basis, budget extra time and QoE cost to normalize the P&L.
• Undisclosed payroll tax liability. Unpaid federal payroll taxes create personal trust fund liability (IRC §6672) for whoever was responsible. These don't go away in an asset sale — the IRS pursues individuals, not just the entity. Verify payroll tax deposit history through EFTPS or request IRS transcripts.
• Worker misclassification exposure. Businesses with large 1099 contractor workforces often have classification risk. Misclassified workers create §3509 back-tax liability. Review worker classification before close. See the worker classification guide for penalty math.
• Owner-dependence on key relationships. If the founder is the primary rainmaker and won't stay post-close, you're buying a customer list. Structure a transition period and earnout tied to customer retention, or reduce the purchase price to reflect the risk.
• Cash-basis deferred revenue. Subscription or prepaid service businesses often show revenue in cash receipts that haven't been earned. In an asset sale, ensure deferred revenue liabilities are properly excluded or priced in.

Step 6: Post-acquisition financial planning

Acquisition closes — now the financial optimization clock starts. Decisions made in the first 12 months set the tax and wealth trajectory for the life of your ownership.

Entity structure review

If you acquired via a stock purchase, you inherited the seller's entity. Evaluate whether the current structure is optimal. The S-corp election (Form 2553) has a 75-day window from the start of the new tax year — if you want S-corp treatment for the acquisition year, the clock may already be running.

• S-corp salary/distribution split. Establish a reasonable compensation level immediately to optimize FICA exposure and protect your §199A QBI deduction. See the S-corp reasonable compensation guide.
• Section 199A QBI deduction. Pass-through business income may qualify for the 20% QBI deduction (2026 MFJ phaseout starts at $403,500 for SSTBs). Use the QBI calculator to estimate your deduction based on the acquired business's income.
• Built-in gains period. If you acquired a C-corp and converted it to S-corp status, any gains inherent at the conversion date face corporate-level tax under IRC §1374 if recognized within 5 years. Track the BIG recognition window carefully.

Retirement plan strategy

The acquired business may have no plan, a suboptimal plan, or an existing plan with compliance issues under your ownership. Immediate priorities:

• Solo 401(k) if owner-only or owner + spouse. Allows up to $72,000 in contributions in 2026 — $24,500 employee deferral plus up to $47,500 employer profit-sharing. Add a Roth Solo 401(k) option for tax-free compounding. See the Solo 401(k) guide.
• Cash Balance Plan stacking. If the business generates substantial owner income, a cash balance plan stacked on a Solo 401(k) can shelter $200K–$400K+ per year tax-deferred for owners over 45.
• SIMPLE IRA termination timing. If the acquired business has a SIMPLE IRA, you cannot terminate it mid-year — termination requires 60-day advance notice and takes effect December 31. Plan accordingly.
• Existing 401(k) compliance review. An inherited 401(k) or profit-sharing plan may now fail ADP/ACP or top-heavy tests given a new ownership structure and employee census. Get a third-party administrator (TPA) review immediately after close.

Year-one tax integration

If the deal was structured as an asset purchase or §338(h)(10), you have fresh depreciation basis. Maximize it in year one:

• OBBBA 100% bonus depreciation. Qualifying personal property placed in service after January 19, 2025 can be fully expensed in year one. New equipment, computers, furniture, and software acquired at closing (or shortly after) may qualify.
• §179 expensing ($2,560,000 limit in 2026). An alternative or complement to bonus depreciation. Cannot generate a net loss (bonus depreciation can). Use for assets where immediate expensing is most valuable.
• §197 intangibles amortization. Begin 15-year straight-line amortization on goodwill and identified intangibles in the month of acquisition. This generates a predictable, substantial annual deduction.
• Start exit planning immediately. The 10-year planning window for your next exit starts on day one of ownership. If the acquired entity is a C-corp and you want QSBS eligibility, the 5-year holding clock begins at original share issuance. See the business exit planning roadmap.
