Sale of an LLC: Section 754 Step-Up Election

Most mid-market businesses in the United States are structured as LLCs taxed as partnerships. The LLC provides liability protection while partnership taxation provides a single layer of tax — income passes through to the members and is taxed once at the individual level. This structure works well during operations. It also creates a significant advantage at exit, because partnership tax law includes a provision that no other entity type can match: IRC section 754.

Section 754 allows a partnership to elect to adjust the inside basis of its assets when a partnership interest changes hands. The adjustment, calculated under section 743(b), steps up (or steps down) the new partner's share of the entity's asset basis to match the purchase price. This means a buyer who pays $20 million for an LLC with $3 million of inside basis can create $17 million of new depreciable and amortizable basis — the same economic benefit the buyer would receive in an asset purchase — without requiring the entity to sell a single asset. The seller recognizes gain on the sale of a membership interest, not on an entity-level asset disposition, which avoids entity-level taxes, preserves the entity's contracts and licenses, and simplifies the closing mechanics.

Why the 754 election matters in a sale

The fundamental tension in every business acquisition is that sellers want to sell equity (one layer of tax at the individual level) and buyers want to buy assets (stepped-up basis for future depreciation and amortization). In a C-corporation or S-corporation, this tension has no clean resolution — one side wins and the other compromises. In a partnership or LLC taxed as a partnership, the 754 election resolves the tension almost entirely.

Consider a buyer evaluating a $20 million acquisition of an LLC. The LLC's assets have an inside tax basis of $3 million — the remainder of the value is goodwill, customer relationships, and intellectual property built over years of operations. Without a 754 election, the buyer purchases membership interests and inherits the $3 million inside basis. The buyer cannot depreciate or amortize the $17 million premium over the historic basis. At a 21% tax rate, the lost cost-recovery deductions are worth approximately $3.57 million in undiscounted tax savings over 15 years (the section 197 amortization period for most intangibles). No rational buyer ignores this number.

With a 754 election, the buyer still purchases membership interests — but the partnership files a section 743(b) adjustment that allocates the $17 million basis step-up across the LLC's assets at fair market value. The buyer amortizes goodwill over 15 years, depreciates equipment over 5 to 7 years under MACRS, and depreciates real property over 27.5 or 39 years. The present-value tax benefit depends on the asset mix, but for a typical services or SaaS business where most of the value is in goodwill and intangibles, the buyer recovers roughly $3 million to $4 million in tax savings over the amortization period.

How the section 743(b) adjustment works mechanically

When a buyer purchases a partnership interest and a 754 election is in effect, the partnership computes the buyer's section 743(b) adjustment as the difference between: (a) the buyer's outside basis in the partnership interest (generally the purchase price plus any share of partnership liabilities assumed), and (b) the buyer's proportionate share of the partnership's inside basis in its assets.

For a 100% acquisition at $20 million where the partnership's total inside basis is $3 million and the buyer assumes no partnership-level liabilities:

• Buyer's outside basis: $20,000,000
• Buyer's share of inside basis: $3,000,000
• Section 743(b) adjustment: $17,000,000

This $17 million adjustment is then allocated under section 755 across two classes of assets: ordinary income property (inventory, receivables, and unrealized receivables) and capital gain property (equipment, real estate, goodwill, and other section 197 intangibles). The allocation within each class follows the difference between fair market value and existing basis for each individual asset. A qualified appraisal at closing is essential — the IRS scrutinizes section 755 allocations that are skewed toward short-lived asset classes to accelerate deductions.

The 743(b) adjustment is personal to the buyer. It appears as a special basis adjustment on the buyer's Schedule K-1 and does not affect the partnership's books, the other partners' basis, or the entity's tax return beyond the required disclosure. In a 100% acquisition, this distinction is mechanical — but in partial acquisitions where existing partners remain, the personal nature of the adjustment is critical: only the new buyer benefits from the step-up.

754 election versus asset sale: side-by-side comparison

The following comparison assumes a $20 million sale of an LLC taxed as a partnership with $3 million of inside basis, held by a single founder with a $500,000 outside basis.

Asset sale at $20 million

• Entity sells all assets for $20 million. Entity-level gain: $17 million.
• Gain flows through to the seller on Schedule K-1. Character depends on asset class — a portion may be ordinary income (hot assets under section 751), the remainder is long-term capital gain.
• Buyer takes a cost basis of $20 million in the acquired assets. Full depreciation and amortization available immediately.
• In states with entity-level taxes (Texas franchise tax, California LLC fee), the entity-level gain inflates the tax base. Texas franchise tax on a $20 million revenue spike: approximately $105,000 to $120,000 additional tax.
• Every contract, license, permit, and lease must be retitled or assigned to the buyer — triggering change-of-control provisions, consent requirements, and potential anti-assignment clauses.
• The entity's tax ID changes hands or a new entity is created. Government contracts, regulatory approvals, and bank relationships may require reapplication.

Interest sale with 754 election at $20 million

• Seller sells 100% of membership interests for $20 million. Seller recognizes $19.5 million gain ($20 million minus $500,000 outside basis).
• No entity-level gain. Entity does not sell assets. Entity's total revenue for state tax purposes reflects only normal operations.
• 754 election creates a $17 million section 743(b) adjustment. Buyer amortizes and depreciates as if assets were purchased at fair market value.
• No state entity-level tax spike. Texas franchise tax stays at normal operating levels — saving approximately $100,000+ compared to the asset sale.
• Entity retains its tax ID, contracts, licenses, permits, and regulatory approvals. No retitling required.
• Closing mechanics are simpler: a single membership interest purchase agreement replaces the bill of sale, assignment agreements, and asset schedules required in an asset deal.

The seller's federal tax liability is similar in both structures — the gain amount is comparable and the character of gain under section 751 hot-asset rules applies in both cases. The difference is at the entity and state level: the interest sale with 754 avoids entity-level gain recognition and the associated state tax consequences. For the buyer, the 754 election produces substantially the same basis step-up as an asset purchase. The combined result: the interest sale with 754 is Pareto-superior to the asset sale for partnerships — both sides are at least as well off, and usually better off.

The hot-asset trap: section 751 in interest sales

One complication the 754 election does not eliminate is section 751. When a partner sells a partnership interest, any gain attributable to "hot assets" — unrealized receivables (including recapture amounts) and substantially appreciated inventory — is taxed as ordinary income, not capital gain. This is true regardless of whether the transaction is structured as an asset sale or an interest sale. Section 751 ensures that the character of income is preserved: the seller cannot convert what would have been ordinary income in an asset sale into capital gain simply by selling a partnership interest instead.

For most mid-market service and technology businesses, the hot-asset exposure is relatively small — limited to accounts receivable and any depreciation recapture on equipment. But for businesses with significant inventory (distributors, manufacturers, retailers), the section 751 ordinary income component can be substantial. The seller's tax advisor should prepare a section 751 analysis before closing to quantify the ordinary income component and ensure the purchase price allocation is consistent between buyer and seller.

Worked example: $20 million SaaS LLC exit

Priya founded CloudBridge, a Texas LLC taxed as a partnership, in 2020. She holds 100% of the membership interests with an outside basis of $400,000 (her original capital contribution plus six years of retained earnings adjustments). CloudBridge has $6 million in annual recurring revenue, $2.4 million in EBITDA, and has been valued at $20 million (approximately 3.3x revenue). The LLC's assets have an inside basis of $2.8 million: $400,000 in equipment, $200,000 in receivables, and $2.2 million in capitalized software development costs. The remaining $17.2 million of value is attributable to goodwill, customer relationships, and assembled workforce.

Structure A: asset sale

• Entity sells all assets for $20 million. Entity-level gain: $17.2 million.
• Section 751 ordinary income (receivables and depreciation recapture): approximately $350,000.
• Long-term capital gain: approximately $16.85 million.
• Federal tax on ordinary income ($350,000 at 37%): $129,500.
• Federal tax on LTCG ($16.85 million at 23.8%): $4,010,300.
• Texas franchise tax on $26 million total entity revenue ($6M operating + $20M sale): approximately $136,500 (after 30% standard deduction, at 0.75%).
• Total tax burden: approximately $4,276,300.
• After-tax proceeds: approximately $15,724,000.

Structure B: interest sale with 754 election

• Priya sells 100% of her membership interests for $20 million. Individual-level gain: $19.6 million ($20M minus $400K outside basis).
• Section 751 ordinary income: approximately $350,000 (same — section 751 applies in interest sales too).
• Long-term capital gain: approximately $19.25 million.
• Federal tax on ordinary income ($350,000 at 37%): $129,500.
• Federal tax on LTCG ($19.25 million at 23.8%): $4,581,500.
• Texas franchise tax: normal operating level only — approximately $24,000 (no entity-level sale revenue).
• Total tax burden: approximately $4,735,000.
• After-tax proceeds: approximately $15,265,000.

At first glance, the interest sale produces slightly lower after-tax proceeds for Priya — the gain on the interest sale ($19.6 million) is higher than the gain on the asset sale ($17.2 million) because the outside basis ($400,000) is lower than the inside basis ($2.8 million). But this is not the full picture. The buyer's willingness to pay is affected by the tax benefit the buyer receives. In an asset sale, the buyer gets $17.2 million of depreciable and amortizable basis automatically. In an interest sale without a 754 election, the buyer gets only $2.8 million. The 754 election gives the buyer $17.2 million in basis adjustment — equivalent to the asset sale.

Because the buyer receives the same tax benefit in both structures (with the 754 election), the buyer should be willing to pay the same price. And because the interest sale avoids $112,500 in additional Texas franchise tax ($136,500 minus $24,000), that savings is available to be shared between the parties. In practice, the seller captures most of this savings because the buyer is indifferent between the two structures when a 754 election is in place. Priya's effective net benefit from the interest-sale-with-754 structure: approximately $112,500 in avoided state franchise tax, partially offset by the higher federal gain — but the franchise tax savings and closing simplicity make this the preferred structure.

When the 754 election is not available or not sufficient

The 754 election is powerful but has boundaries. It is not available for S-corporations or C-corporations — only for entities taxed under subchapter K (partnerships and multi-member LLCs). Single-member LLCs that are disregarded for tax purposes do not file partnership returns and cannot make a 754 election; a sale of a disregarded entity's interests is treated as an asset sale by default under Treasury Regulation 1.1001-1(a). Founders who hold their business in a single-member LLC should consider admitting a nominal second member before a sale to enable partnership treatment and the 754 election — though this planning must be done well in advance of the transaction to withstand IRS scrutiny.

The 754 election also does not solve the section 751 hot-asset problem. Regardless of deal structure, gain attributable to unrealized receivables and substantially appreciated inventory is taxed as ordinary income. For businesses with significant hot-asset exposure — manufacturers with large inventory, professional service firms with substantial unbilled receivables — the ordinary income component may be the dominant tax issue, and the 754 election does not change it.

Finally, the 754 election is irrevocable without IRS consent. Once made, it applies to all future transfers of partnership interests — including internal transfers among existing partners, gifts, and inherited interests. For partnerships that expect frequent ownership changes outside of the sale context, the administrative burden of computing 743(b) adjustments for every transfer can be significant. That said, for a full sale of the business, this concern is moot — the entity will have a single new owner, and the 754 election applies exactly once.

Interaction with QSBS and entity selection

Section 1202 QSBS exclusion allows founders of qualified small businesses to exclude up to the greater of $10 million or 10 times adjusted basis from federal capital gains tax on the sale of qualified small business stock. The exclusion is available only for C-corporation stock — not LLC membership interests. This creates a strategic tension at formation: should a founder choose an LLC (with the 754 election benefit at exit) or a C-corporation (with the QSBS exclusion at exit)?

For a $20 million exit, the QSBS exclusion can eliminate federal capital gains tax on up to $10 million of gain — saving approximately $2.38 million (at 23.8%). The 754 election, by contrast, primarily benefits the buyer and provides the seller with indirect savings through avoided state taxes and negotiating leverage. The QSBS benefit to the seller is direct and large; the 754 benefit to the seller is indirect and smaller. For founders who anticipate a mid-market exit exceeding $10 million, the optimal structure depends on the state tax environment, the expected deal size relative to the QSBS cap, and whether the buyer pool will demand asset-sale treatment.

Pre-sale planning for the 754 election

• Confirm partnership tax status. The 754 election requires the entity to be taxed as a partnership under subchapter K. Multi-member LLCs default to partnership status. Single-member LLCs are disregarded entities — consider admitting a second member well in advance if a 754 election is part of the exit plan.
• Prepare a current asset appraisal. The section 755 allocation of the 743(b) adjustment requires fair market values for every asset class. A qualified appraisal performed at or near closing establishes defensible values and reduces audit risk.
• Quantify the hot-asset exposure. Run a section 751 analysis to determine how much of the gain will be recharacterized as ordinary income. This number affects the seller's tax liability regardless of deal structure and should be factored into the purchase price negotiation.
• Model the buyer's tax benefit. Calculate the present value of the buyer's depreciation and amortization deductions under the 754 election. This number is the buyer's incentive to accept an interest sale instead of demanding an asset sale — and it becomes a negotiation tool for the seller.
• Address state tax implications. In states with entity-level taxes (Texas, California, New York), the interest-sale structure avoids entity-level revenue spikes. Quantify the state tax savings and include them in the total deal economics.
• Coordinate with the operating agreement. The LLC's operating agreement should authorize the tax matters partner (or partnership representative under the BBA rules) to make the 754 election. If the agreement is silent, the election may require unanimous member consent — which becomes complicated in a contested sale or multi-member exit.

Key takeaways

• The section 754 election is the single most important structural advantage of selling a business held in an LLC taxed as a partnership. It allows the buyer to receive a stepped-up basis in the LLC's assets — equivalent to an asset purchase — while the seller structures the transaction as an interest sale, avoiding entity-level gain recognition and state entity-level taxes.
• The 743(b) basis adjustment is allocated under section 755 across ordinary income property and capital gain property based on fair market values. A qualified appraisal at closing is essential to support the allocation and maximize the buyer's cost-recovery deductions.
• Section 751 applies to interest sales just as it applies to asset sales. Gain attributable to hot assets — unrealized receivables and substantially appreciated inventory — is taxed as ordinary income regardless of deal structure. The 754 election does not change this characterization.
• The 754 election is available only for partnerships and LLCs taxed as partnerships. S-corporations use section 338(h)(10) elections, and C-corporations use section 336(e) elections — neither provides the seller-friendly benefit of avoiding entity-level gain while giving the buyer a basis step-up.
• For founders choosing between LLC and C-corporation structure at formation, the tradeoff is the 754 election at exit (LLC) versus the section 1202 QSBS exclusion at exit (C-corp). The QSBS exclusion provides a direct seller benefit of up to $2.38 million in avoided federal tax on $10 million of gain. The 754 election provides indirect seller benefits through state tax savings and negotiating leverage. The optimal choice depends on expected deal size, state tax environment, and buyer composition.
• Single-member LLCs cannot make a 754 election because they are not taxed as partnerships. Founders holding businesses in single-member LLCs should consider admitting a nominal second member well before a planned exit to enable partnership treatment and the 754 election — though this must be done with care to avoid IRS challenge.
