Personal Goodwill + Sec. 280G Golden Parachute: $10M+ Math

For a C-corporation founder selling a $10M-plus business in an asset sale, the two most consequential tax doctrines in the deal are personal goodwill and the IRC sec. 280G golden parachute rules. The first is offensive: a properly documented personal goodwill carve-out can move $3M to $5M of the purchase price from the corporation's ledger (where it would face double-tax at a 38-40 percent effective rate) onto the founder's personal return (where it is single-taxed at 23.8 percent). The second is defensive: sec. 280G imposes a 20 percent excise tax on the founder plus disallows the buyer's deduction when compensation tied to the change-in-control exceeds three times the founder's historical W-2. Get personal goodwill right and you save $1.5M to $3M. Get 280G wrong and you cost yourself $250K to $500K. The two issues must be planned together because the buyer's allocation, the founder's post-closing role, and the parachute calculation all reference the same facts.

Personal goodwill: the Martin Ice Cream doctrine

The leading personal goodwill cases are Martin Ice Cream Co. v. Commissioner (110 T.C. 189) and Norwalk v. Commissioner (T.C. Memo 1998-279). The doctrine recognizes that some businesses derive substantial value from the personal attributes of an individual — the founder's relationships, reputation, sales skills, technical expertise — rather than from the corporate entity. When the business is sold and those personal attributes are part of what the buyer is paying for, the founder can sell that personal goodwill directly to the buyer, separate from the corporation's sale of its enterprise goodwill.

The tax consequence is dramatic in a C-corp asset sale. In a standard C-corp asset sale of a $10M business:

• Corporation sells assets for $10M, recognizes gain
• Corporation pays 21 percent federal corporate tax on the gain
• Corporation distributes the after-tax proceeds to the shareholder
• Shareholder pays 23.8 percent LTCG-plus-NIIT on the liquidating distribution
• Combined effective rate: 38 to 40 percent

With a personal goodwill carve-out, say $3M of the $10M purchase price:

• Corporation sells $7M of assets, recognizes gain, pays 21 percent corporate tax, distributes after-tax to shareholder, shareholder pays 23.8 percent on distribution
• Founder sells $3M of personal goodwill directly to the buyer, recognizes capital gain (after subtracting basis, often $0 for self-created goodwill), pays 23.8 percent LTCG-plus-NIIT
• Federal tax savings on the $3M carve-out: approximately $440,000 (38 percent on $3M = $1.14M reduced to 23.8 percent on $3M = $714K)

The factors that make personal goodwill defensible

Personal goodwill is one of the most heavily scrutinized positions in M&A taxation. The IRS aggressively challenges it on audit; the Tax Court has decided both for taxpayers (Martin Ice Cream, Norwalk, H&M Inc.) and against them (Solomon Colors, Howard, Bross Trucking). The strongest fact patterns share several characteristics:

• Solo or near-solo founder. Personal goodwill is easiest to establish when one individual is the face of the business. Multi-shareholder companies with multiple key relationship holders have a harder time arguing that any single individual's goodwill is personal rather than enterprise.
• No non-compete agreement with the corporation. A pre-existing non-compete between the founder and the corporation transfers personal goodwill to the corporation under Howard and Bross Trucking. If the founder cannot compete, the corporation has effectively acquired the goodwill. Founders considering personal goodwill should not sign blanket non-competes with their own C-corps.
• No corporate intangibles covering the same goodwill. If the corporation owns a registered trademark, customer-list intangible, franchise agreement, or trade name that covers the same customer relationships, the corporation owns the goodwill. Personal goodwill is strongest when the founder's name and reputation — not the corporation's — are the brand.
• Direct customer relationships. The founder personally signs contracts, services key accounts, manages sales, and is the named principal in customer communications. Customers think of the business as "the founder."
• Limited corporate marketing infrastructure. A company with substantial enterprise marketing assets (national advertising, brand campaigns, salesforce trained on corporate methods) has enterprise goodwill, not personal goodwill. Personal goodwill is strongest in professional services, niche consulting, single-author content, and relationship-driven sales businesses.
• Independent appraisal. A qualified business appraiser values the corporation's enterprise goodwill and the founder's personal goodwill separately, supported by industry benchmarks and the specific factual record. Self-determined allocations without independent support fail on audit.
• Separate purchase agreements. The corporation signs an asset purchase agreement with the buyer; the founder signs a separate personal goodwill purchase agreement with the buyer. The two agreements are negotiated together but documented separately.

IRC sec. 280G: golden parachute rules

Section 280G applies when a corporation undergoes a change in ownership or control and makes "parachute payments" to "disqualified individuals." The mechanics:

• Disqualified individuals: officers, directors, shareholders owning more than 1 percent of the corporation's stock value, and highly compensated employees (top 1 percent of employees by compensation).
• Parachute payments: any compensation contingent on a change in ownership or control. Includes: severance, accelerated equity vesting, transaction bonuses, retention bonuses, non-compete payments, consulting fees connected to the deal, accelerated deferred compensation.
• Base amount: the disqualified individual's average annual W-2 compensation over the five tax years preceding the change-in-control year.
• Three-times threshold: if total parachute payments exceed three times the base amount, sec. 280G applies.
• Excess parachute amount: the amount by which total parachute payments exceed one times the base amount.
• Excise tax: 20 percent on the excess parachute amount, imposed on the recipient under sec. 4999.
• Deduction disallowance: the corporation cannot deduct the excess parachute amount under sec. 280G(a).

The mechanics are intentionally punitive: the excise tax is on top of the recipient's regular income tax, and the corporation loses the deduction. For a founder with a $250K base amount who receives $2M of change-in-control compensation:

• Three-times threshold: $750,000. Exceeded.
• Excess parachute amount: $2,000,000 − $250,000 (one times base amount) = $1,750,000
• Excise tax at 20%: $350,000
• Plus regular income tax on the $2M at 37% + 3.8% NIIT + 0.9% additional Medicare: ~$835,000
• Total federal tax on the $2M of compensation: ~$1,185,000 (effective rate near 60%)
• Corporation also loses the $1,750,000 deduction at 21% = $367,500 of additional corporate tax

The sec. 280G(b)(5)(B) shareholder-vote exemption

Private companies (not publicly traded) can avoid 280G entirely through the shareholder-vote exemption under sec. 280G(b)(5)(B). The vote requirements:

• More than 75 percent of voting power must approve the parachute payments
• Vote must be by disinterested shareholders — the disqualified individual receiving the payments cannot vote
• Full disclosure of all parachute payments and their material terms before the vote
• Vote must occur before the change in control — typically 30 to 45 days before closing

The mechanical challenge: in many founder-controlled companies, the founder is the 80 to 100 percent shareholder. If the founder is the only shareholder and the only disqualified individual, no disinterested shareholders exist to vote. The shareholder-vote exemption is then unavailable. For founders with significant minority shareholders (investors, employees with ISOs/RSUs, founders' family members), the 75 percent disinterested-shareholder vote is usually achievable with sufficient lead time.

The disclosure document is the bottleneck. Counsel must prepare a comprehensive description of every parachute payment (amount, structure, timing, contingencies), the base amount calculation for each disqualified individual, and the resulting 280G exposure. The disclosure is signed by the disqualified individuals, distributed to shareholders, and the vote occurs in writing or at a meeting. Closing cannot occur until the vote is recorded.

Personal goodwill and 280G interaction

The two doctrines collide at the founder's post-closing role. Personal goodwill requires the founder to be the face of the business — which often means a multi-year consulting or employment agreement post-closing to ensure customer relationships transfer smoothly. But that same post-closing arrangement looks like compensation under 280G.

The IRS often takes the position that:

• Personal goodwill payments are really disguised compensation for post-closing services
• Or the post-closing consulting agreement is below-market, indicating the personal goodwill payment is the real compensation

The defense:

• Independent appraisal supporting the personal goodwill value as the FMV of the goodwill itself, separate from any post-closing services
• Market-rate post-closing compensation — the founder's consulting or employment agreement pays a market rate benchmarked to comparable executive roles
• Pro-rata allocation — if other shareholders are also selling, the personal goodwill carve-out should be consistent with the founder's percentage of the personal goodwill, not a special founder-only payment
• Clean documentation — separate purchase agreement for personal goodwill, separate consulting agreement at market terms, no cross-references between the two

Worked example: $14M C-corp asset sale with personal goodwill and 280G

Helena founded Apex Consulting, a Delaware C-corp providing specialized actuarial consulting to insurance companies. She is the sole shareholder, with $100K of stock basis. The company has $1.8M of annual EBITDA. Helena is the primary client contact for 80 percent of revenue, the named principal on all engagements, and the only equity owner. Her base amount for 280G (five-year average W-2): $400,000.

In April 2026, a strategic buyer offers $14M for the assets. The deal structure: $9M to the corporation for enterprise assets, $4M to Helena personally for personal goodwill, $1M of change-in-control compensation (signing bonus plus accelerated deferred comp). Helena will continue as a senior consultant for three years at $250K per year.

Scenario A: Standard C-corp asset sale (no personal goodwill)

• Corporation sells all $14M of assets
• Corporate gain: $14,000,000 − $400,000 corporate basis = $13,600,000
• Corporate tax at 21%: $2,856,000
• After-tax to distribute: $11,144,000
• Liquidating distribution: $11,144,000 − $100,000 stock basis = $11,044,000
• Shareholder tax at 23.8%: $2,628,472
• Total federal tax: $5,484,472
• Plus 280G excise tax on $1M change-in-control comp (base = $400K, three-times = $1.2M, threshold NOT crossed): $0 excise tax
• Plus regular income tax on $1M comp at 37% + 3.8% + 0.9%: ~$417,000
• Total federal tax: ~$5,901,472
• Helena keeps: ~$8,098,528

Scenario B: With personal goodwill carve-out and 280G management

• Corporation sells $9M of enterprise assets
• Corporate gain: $9,000,000 − $400,000 = $8,600,000
• Corporate tax at 21%: $1,806,000
• After-tax to distribute: $7,194,000
• Liquidating distribution: $7,194,000 − $100,000 stock basis = $7,094,000
• Shareholder tax at 23.8%: $1,688,372
• Personal goodwill: Helena sells $4M of personal goodwill direct to buyer
• Helena's basis in personal goodwill: $0 (self-created)
• Capital gain on personal goodwill: $4,000,000
• Tax at 23.8%: $952,000
• Change-in-control compensation: $1,000,000
• Base amount: $400K, three-times: $1.2M. $1M NOT crossing threshold — no 280G.
• Income tax on $1M at 37% + 3.8% + 0.9%: ~$417,000
• Total federal tax: $1,806,000 + $1,688,372 + $952,000 + $417,000 = $4,863,372
• Helena keeps: ~$9,136,628

Scenario C: If Helena's comp had been $2M (280G triggered)

• Same as Scenario B except change-in-control comp = $2M instead of $1M
• Three-times threshold: $1.2M. Exceeded.
• Excess parachute amount: $2,000,000 − $400,000 (one-times base) = $1,600,000
• Excise tax at 20% on $1,600,000: $320,000
• Plus income tax on $2M at ~41.7%: ~$834,000
• Total federal tax on the $2M comp: $1,154,000 (57.7% effective rate)
• Corporation loses deduction on $1,600,000 at 21% = $336,000 additional corp tax (passes through to net deal proceeds)

Scenario C with 280G(b)(5)(B) shareholder vote

Helena is the sole shareholder, so the shareholder-vote exemption is unavailable (no disinterested shareholders exist). If she had granted 10 percent of the equity to a co-founder or trusted employee 5 to 10 years before the sale, that 10 percent shareholder could vote in favor of waiving 280G, exempting the parachute payments from the excise tax. Savings: $320,000 of excise tax plus $336,000 of lost corporate deduction = approximately $656,000 of additional after-tax proceeds.

The strategic lesson: founders considering a future exit should structure their cap table with at least 25 percent disinterested ownership well before the change-in-control year, to preserve access to the 280G(b)(5)(B) exemption. Common patterns: 10 to 25 percent equity grants to senior employees, co-founder splits, gifts to family members in irrevocable trusts.

Pre-sale structuring to support personal goodwill

Several pre-sale steps strengthen the personal goodwill position:

• Avoid signing non-competes with the corporation. A non-compete transfers personal goodwill to the corporation under Howard. If a non-compete exists, evaluate whether it can be released or modified before sale.
• Document the founder's personal role. Customer-facing communications under the founder's name, customer testimonials referencing the founder personally, marketing materials featuring the founder, industry recognition of the founder (not the corporation). All build the factual record for personal goodwill.
• Limit corporate intangibles covering the same goodwill. If the corporation has a trademark covering the founder's name, transfer it to the founder personally. If the corporation has a customer-list intangible on its books, consider distributing it to the founder under sec. 311 before the sale (with appropriate planning for the distribution's tax consequences).
• Engage independent counsel and appraiser early. The personal goodwill allocation should be supported by an appraisal prepared during deal negotiations, not after the LOI is signed. The appraiser's methodology, comparables, and conclusions should be documented in a written report.
• Negotiate the buyer's consent. Personal goodwill is a buyer-cooperative position. The buyer must agree to structure the transaction as two separate purchases (corporation's assets plus founder's personal goodwill). Sophisticated buyers understand this and accept it; less experienced buyers may resist because the documentation is more complex.

State-tax considerations

States generally follow the federal characterization of personal goodwill, but a few states have specific rules. California (Cal. Code Regs. tit. 18 sec. 17951-5) sources personal goodwill to the state where the goodwill was developed, which for a California founder means CA tax at 13.3 percent regardless of post-sale residency. This means a California founder relocating to Nevada before the sale cannot easily escape state tax on the personal goodwill component if the FTB can establish the goodwill was developed during CA residency.

New York similarly aggressively sources personal goodwill to the state of development. For founders considering a personal goodwill strategy, the state-tax implications of the founder's pre-sale residency history can be material — and may affect whether the personal goodwill carve-out is net beneficial after both federal savings and incremental state-tax exposure.

Key takeaways

• Personal goodwill under Martin Ice Cream and Norwalk lets a founder sell goodwill directly to the buyer, separate from the C-corp's enterprise sale. The carve-out converts double-taxed corporate gain (38 to 40 percent combined) into single-taxed LTCG (23.8 percent), saving $1.5M to $3M on a $10M+ asset sale.
• Personal goodwill is strongest when the founder is the sole or primary owner, has no non-compete with the corporation, the corporation has no enterprise intangibles covering the same relationships, and the founder is the customer-facing principal. Independent appraisal and separate purchase agreements are required.
• IRC sec. 280G imposes a 20 percent excise tax on excess parachute payments when compensation tied to the change-in-control exceeds three times the founder's five-year W-2 average. The excise tax can cost $250K to $500K on a $10M+ deal, plus the corporation loses the deduction on the excess.
• The sec. 280G(b)(5)(B) shareholder-vote exemption avoids 280G entirely for private companies if at least 75 percent of disinterested shareholders approve the parachute payments before closing. Founder-only cap tables cannot use this exemption — pre-sale equity distribution to at least one disinterested shareholder preserves the option.
• Personal goodwill and 280G interact through the founder's post-closing employment. The post-closing role supports personal goodwill but creates 280G exposure. Independent appraisal of the personal goodwill, market-rate post-closing compensation, and clean documentation defend both positions.
• State-tax treatment of personal goodwill varies. California and New York source personal goodwill to the state of development, limiting the ability to relocate pre-sale to capture state-tax savings on the personal goodwill component.
