Personal Goodwill: The Hidden Tax Strategy When Selling Your Business

When you sell a service business, a significant portion of the purchase price often represents relationships and expertise that belong to you personally — not to your corporation. Tax courts have agreed. Structuring that portion as "personal goodwill" allows you to receive it directly, bypassing entity-level tax entirely and keeping the federal rate at 23.8% maximum rather than the 40%+ effective rate that can apply to a C-corp asset sale.

This guide explains what personal goodwill is, who has it, how it's documented, how C-corp and S-corp owners use it differently, and how to defend it if the IRS pushes back.

Personal goodwill vs. enterprise goodwill

Enterprise goodwill is the value that stays with the business regardless of who owns it — a national brand, a proprietary system, recurring contracts that aren't dependent on the founder, or a diversified customer base built over decades. If you sold the business and walked away, enterprise goodwill transfers seamlessly to the buyer.

Personal goodwill is the value attached to you specifically — your client relationships built on trust and repeated interaction, your professional reputation in a market, your technical expertise that customers buy, or your supplier access based on your personal history. If you left tomorrow and took those relationships with you, the business would be worth materially less.

The distinction matters because the tax treatment is completely different:

The tax math for C-corp owners

The benefit is most dramatic in a C-corp asset sale, where enterprise goodwill faces double taxation — 21% at the corporate level, then 15–23.8% again when the proceeds are distributed as a dividend. The combined federal rate can reach 40% or more.

Personal goodwill bypasses the corporation entirely. You sell it directly to the buyer as an individual. The gain is long-term capital gain taxed at your individual rate:¹

• 0% if your taxable income is below $98,900 (MFJ, 2026) — rare for a business seller, but useful for bracket-filling in a multi-year installment sale
• 15% for most sellers with incomes up to $613,700 (MFJ, 2026)
• 20% above $613,700 (MFJ), plus 3.8% NIIT above $250,000 MAGI — maximum 23.8% federal

The legal foundation: Martin Ice Cream (1998)

The Tax Court established the personal goodwill doctrine in Martin Ice Cream Co. v. Commissioner, 110 T.C. 189 (1998). Arnold Strassberg had built close relationships with supermarket chains over decades, giving Martin Ice Cream access to distribution. When Häagen-Dazs acquired the company, it paid $1.4M specifically for those relationships.

The IRS argued the payment was corporate income — the relationships were a corporate asset. The Tax Court disagreed. Because Strassberg had no employment contract or non-compete agreement with his own company, those relationships were his property, not the corporation's. They were never assigned to the company and could not be transferred as part of a corporate asset sale without Strassberg's personal participation.²

This case established the two-part test that defines personal goodwill:

1. The goodwill is attributable to the individual's personal skills, relationships, or reputation (not transferable without the individual's ongoing involvement), and
2. There is no agreement — employment contract, non-compete, or covenant — that assigns that goodwill to the corporation.

Which businesses have personal goodwill?

Personal goodwill is most clearly present in businesses where the owner is the product. Common candidates:

• Professional services — consulting, accounting, law, financial advisory, engineering, architecture
• Healthcare practices — physician practices, dental, veterinary, specialty clinics where patient relationships are tied to the provider
• Trades and service businesses — where the owner's technical reputation drives referral volume
• Media and creative — businesses built on a personal brand
• Distribution businesses — where supplier or customer access is based on long-standing personal relationships (the Martin Ice Cream fact pattern)

By contrast, businesses with diverse customer bases, systematic sales processes, and operations that run without owner involvement have less personal goodwill. A franchise, a subscription software business, or a manufacturing company with broad market exposure typically has more enterprise goodwill than personal.

The critical condition: no assignment agreements

The most common reason personal goodwill fails scrutiny is that the owner already assigned it — through an employment agreement, non-compete, or similar covenant — to the corporation.³ Once the corporation has a contractual right to your relationships and expertise, those relationships become a corporate asset regardless of how the sale is structured.

Before assuming you have separable personal goodwill, review:

• Your employment agreement with the company (if any)
• Any non-compete or non-solicitation provisions you signed as an officer or employee
• Shareholder agreements that address goodwill or business development obligations
• Partnership agreements with restrictive covenants

If such agreements exist, personal goodwill may need to be restructured before a sale — or the allocation may not survive challenge. This is one reason exit planning should start 3–5 years before a transaction.

How to structure the transaction

In a deal structured to capture personal goodwill, the purchase agreement will typically include a separate line item: "Purchase of personal goodwill of [Owner Name]." The buyer pays this amount directly to you as an individual — it does not flow through the entity and does not appear on the corporation's tax return as income.⁴

Structuring considerations:

• Separate the covenant not to compete. A non-compete paid to you is taxed as ordinary income. Personal goodwill is capital gain. Push for more goodwill allocation and less non-compete. Buyers often accept this because both are amortized over 15 years under § 197 — they get the same deduction regardless of how the split is labeled.
• Price it defensibly. The IRS scrutinizes personal goodwill allocations. Buyers who pay too much for it face disallowance of the amortization deduction. Both sides need the allocation to reflect economic reality — a valuation expert should support the number.
• Disclose consistently. Both buyer and seller must use the same § 1060 allocation on Form 8594. Inconsistency triggers automatic IRS review.

Valuation: how to support the number

A personal goodwill allocation without a credible valuation is vulnerable. Courts have upheld personal goodwill where the owner could demonstrate:⁵

• What percentage of revenue was attributable to owner-originated relationships
• Customer concentration around the owner (e.g., 60% of revenue from accounts the owner manages personally)
• Evidence that competitors or similar businesses without this owner's profile would sell for less
• A formal business valuation allocating enterprise vs. personal goodwill using accepted methods (excess earnings, comparative transactions)

A qualified business appraiser — ideally a Certified Valuation Analyst (CVA) or Accredited in Business Valuation (ABV) — should prepare a written report supporting the allocation before the transaction closes. Attempting to back into the number after the deal is done is a red flag.

S-corp owners: smaller benefit, still relevant

S-corp asset sales don't have the double-tax problem — goodwill passes through to shareholders at LTCG rates already. But personal goodwill is still relevant in several situations:

• State tax — some states don't fully conform to pass-through treatment and impose entity-level tax on asset sales. Personal goodwill can reduce the entity-level state tax base.
• Basis limitations — if you have at-risk or passive loss limitations at the S-corp level, structuring some gain outside the entity can help you access losses you couldn't otherwise use.
• Former C-corps with built-in gains — if your S-corp converted from a C-corp within the last 5 years, built-in gains tax (§ 1374) at 21% can apply to entity-level asset sale gains. Personal goodwill carved out during the S-corp period avoids this tax.

IRS challenges and how to defend

The IRS has litigated personal goodwill allocations aggressively in cases where they appeared to be engineered rather than genuine. Common IRS arguments:

• "The corporation already owns this goodwill through your employment relationship." Defense: show no assignment agreement existed before the sale.
• "The allocation is too large given the business's diversified revenue." Defense: customer and revenue concentration data; formal valuation.
• "The amount was simply allocated by agreement without economic substance." Defense: allocation reflects what a third-party buyer would rationally pay for the individual's ongoing cooperation.

The Tax Court has upheld personal goodwill when properly documented (Martin Ice Cream, Norwalk v. Commissioner, TC Memo 1998-279) and rejected it when the allocation was unsupported or contradicted by existing covenants (Howard v. United States). Getting the documentation right before signing is the entire game.

Planning timeline

Personal goodwill is much easier to protect when you plan ahead:

• 5+ years out: Audit your employment agreements and shareholder covenants. Don't inadvertently assign your personal relationships to the entity as part of an unrelated transaction or financing.
• 2–3 years out: Begin tracking customer-relationship data in a format that supports a valuation (which accounts did you personally originate and manage?).
• 1 year out: Engage a CVA to perform a preliminary valuation. Use this to set realistic expectations for the allocation in a negotiation.
• At deal time: Separate line item in the purchase agreement. Buyer signs a consulting or transition agreement directly with you, not with the entity. Form 8594 filed consistently by both parties.
