Phantom Equity and Profits Interests in a Business Sale: What You Owe, What They Owe, and How to Plan

Most business owners who reach a $5M–$50M sale have, at some point, given a key employee some form of equity or equity-like arrangement. The label on the document — "phantom stock," "profits interest," "SARs," "restricted stock" — determines the entire tax story at exit. Get it right and your key people keep $1M on a $1.5M payout. Get it wrong and they keep $900K and owe $114K more in FICA. And in both cases, you have to decide how the economics flow through your deal. Here is the complete framework.

Real equity vs. phantom equity: what's actually different

Before getting to the tax rules, it helps to understand the structural difference between the two categories.

Profits interests: real ownership that earns capital gains treatment

A profits interest is an ownership interest in an LLC or partnership that entitles the holder to a share of future profits and appreciation — but not the current value of the entity at the time of grant. If the business were liquidated the day the profits interest was granted, the holder would receive nothing. The profits interest only participates in value created after the grant date.

Why profits interests aren't taxed at grant

The IRS has established a safe harbor in Rev. Proc. 93-27 and Rev. Proc. 2001-43 that treats a profits interest as having zero fair market value at grant, provided three conditions are met:¹

1. The partnership (or LLC taxed as a partnership) is not publicly traded
2. The profits interest is not disposed of within two years of the grant date
3. The profits interest is not a limited partnership interest in a publicly traded partnership

If all three conditions are met, the receipt of the profits interest is not a taxable event — even if vesting is contingent on continued employment or performance. The IRS treats the interest as having no value at grant because there are no current liquidation proceeds allocated to it.

Capital gains treatment at sale

When the business is sold, the profits interest holder participates in the sale proceeds to the extent of their allocated share of appreciation. That gain is treated as capital gain — long-term if the holder has held the interest for more than one year.²

§83(b) elections on profits interests

Despite the Rev. Proc. 93-27 safe harbor, many practitioners file a §83(b) election within 30 days of the profits interest grant. The election treats the interest as property received as compensation with a zero (or nominal) fair market value at grant, and expressly starts the holding period clock at grant rather than at vesting. This provides clean documentation of the holding period start date — particularly useful for multi-year vesting schedules where the LTCG question would otherwise be debated on a tranche-by-tranche basis.

A §83(b) election on a properly issued profits interest typically produces zero ordinary income at grant (because FMV at grant is zero by definition). The upside: clarity on LTCG holding period from day one. The risk: if the business is sold within one year of grant (before the vesting or holding period completes), the safe harbor conditions may not be met and the gain could be recharacterized.

Phantom stock and SARs: deferred compensation taxed as ordinary income

Phantom equity plans — including phantom stock plans, stock appreciation rights (SARs), and similar cash-settled synthetic arrangements — are not ownership interests. They are contractual promises to pay cash tied to the value of the business. At a sale, these plans typically trigger a "change in control" payment: the holder receives cash equal to a percentage of the sale price (phantom stock) or the appreciation above a baseline value (SARs).

Why the tax treatment is fundamentally different

Because phantom equity holders never owned anything — they held a right to receive compensation — the payout is wages, not a return on a capital investment. The full payout is:

• Ordinary income, taxed at marginal rates up to 37% in 2026
• Subject to FICA withholding (Social Security and Medicare taxes)
• Reported on Form W-2 (if an employee)

There is no LTCG treatment available, regardless of how long the employee worked for the business or how long they held the phantom arrangement. A 15-year employee who received phantom stock at founding and receives a $2M payout at closing pays ordinary income rates on the full $2M.⁴

§409A compliance and the change-of-control trigger

All phantom equity plans are nonqualified deferred compensation subject to §409A.⁵ The implications:

• Trigger must be one of six permissible events: separation from service, disability, death, change in control, unforeseeable emergency, or a fixed payment date. A "change in control" (sale of the business) qualifies as a permissible trigger — so a well-drafted phantom equity plan will pay out at a qualifying transaction.
• 409A definition of "change in control": Specific requirements apply (ownership threshold, asset purchase, board change). A plan that pays on any "sale" without meeting the §409A definitions may create a §409A violation — 20% additional tax plus interest at a premium rate, before ordinary income tax is calculated.
• Non-compliant plans: If a phantom equity plan violates §409A (e.g., allows ad-hoc payouts, ambiguous trigger definitions, or incorrect election timing), the entire deferred amount becomes immediately includible as ordinary income plus the 20% penalty. Sellers discover this during due diligence when acquirers audit equity arrangements.

Side-by-side tax math: $15M business, 10% employee equity pool

Assume a business owner sells a $15M enterprise. The owner issued a 10% pool to three key employees approximately four years before the sale — worth $1.5M at sale based on the deal price. The owner is in the 37%/20% rate bracket. Employees are in the 37%/20% bracket (assume pre-sale compensation plus payout puts them at top rates). MFJ assumed throughout.

The same economics for the owner (they share 10% of proceeds either way), but the employees keep meaningfully more with profits interests — and the employer avoids the matching FICA cost. Add state income tax (California is 13.3% on ordinary income vs. 13.3% on LTCG — no difference in CA, but other states vary), and the gap can widen further.

How deal structure interacts with employee equity

Asset sale — the typical outcome for most smaller deals

In an asset sale, the selling entity sells its assets to the buyer. Profits interest holders in an LLC/partnership are owners of the selling entity — at the asset sale, each member (including profits interest holders) recognizes gain allocated through the entity based on their economic interest. The character of that gain follows the assets: goodwill and most capital assets generate capital gain; depreciation recapture on §1245 assets generates ordinary income. Profits interest holders may face a mix of capital gain and ordinary income depending on the asset allocation.

Phantom equity holders do not own the entity — they hold a contractual obligation from the entity. At an asset sale, the company's obligation to pay phantom equity holders survives until triggered. Most phantom equity plans define "change in control" to include an asset sale, so the plan pays out on (or around) the closing date. That payout flows through payroll, is deducted by the company as a compensation expense, and is ordinary income + FICA for the recipient.

Stock sale or membership interest sale

In a stock sale or LLC membership interest sale, the selling owners sell their interests directly to the buyer. Profits interest holders are selling owners — they transfer their membership interests alongside the founder/majority owner and recognize LTCG (assuming the one-year holding period is met).

Phantom equity holders face a structural problem: their rights are against the company, not against the buyer. In most transactions, phantom equity is cashed out at or before closing — funded from the purchase price. The buyer and seller negotiate who funds this obligation. From the seller's perspective, the phantom equity payout typically reduces effective net proceeds: the gross sale price includes a bucket for phantom equity settlement, so the seller receives less cash after paying the plan.

Stock-for-stock mergers (rare for private company exits)

If the consideration is stock (acquirer shares) rather than cash, profits interest holders can potentially receive the acquirer's stock, allowing continued deferral under §351 (if properly structured). Phantom equity holders typically cannot hold phantom interests in the acquirer's stock structure — the plan pays out in cash at change of control regardless, triggering ordinary income even in a stock deal.

The FICA cost that surprises sellers at closing

Most business owners understand that phantom equity payouts generate ordinary income tax for employees. Fewer anticipate the FICA cost that falls on the employer.

In 2026, the FICA structure is:

• Social Security tax: 6.2% employee + 6.2% employer on wages up to $184,500⁶
• Medicare tax: 1.45% employee + 1.45% employer on all wages (no ceiling)
• Additional Medicare tax: 0.9% employee-only on wages exceeding $200,000 (single) / $250,000 (MFJ); no employer match on this portion

For a phantom equity payout of $1.5M distributed across three employees who have already earned salaries above $184,500 in 2026:

• No Social Security applies (wage base already exceeded by salary)
• Employee Medicare: 1.45% × $1,500,000 = $21,750
• Additional Medicare (employee, assuming over threshold): 0.9% × $1,500,000 = $13,500
• Employer Medicare: 1.45% × $1,500,000 = $21,750
• Total FICA: $57,000 — of which $21,750 is an out-of-pocket employer cost at closing

For employees earning below the $184,500 wage base before the phantom equity payout, Social Security tax applies on the gap. A $300K phantom equity payout to a recipient earning $80K in salary would add: SS employee on $104,500 = $6,479; SS employer on $104,500 = $6,479 — an additional ~$13K in employer FICA cost for that recipient alone.

This cost is real, comes out of closing proceeds, and is frequently not modeled until the final settlement statement. An exit-planning advisor should be modeling gross phantom equity obligations + employer FICA as part of your net proceeds calculation.

QSBS interaction: profits interests don't qualify, stock can

Section 1202 (QSBS) excludes up to $15M per taxpayer in capital gain from the sale of qualifying C-corporation stock. Profits interests in LLCs do not qualify — §1202 requires "stock in a domestic C corporation."⁷

However, if the business operates as a C-corp and employees hold actual restricted stock (not phantom equity), that stock can qualify for QSBS exclusion if:

• The stock was acquired as original-issue stock from the corporation at original issuance or a qualifying secondary transfer
• The aggregate gross assets of the corporation were under $75M at the time of issuance
• The stock is held for more than five years
• The corporation was a qualified small business throughout the holding period
• A §83(b) election was filed (if stock was subject to a vesting schedule) to start the QSBS clock at grant, not at vesting

Post-OBBBA (July 2025), the §1202 exclusion is 50% at 3 years, 75% at 4 years, 100% at 5 years — for stock issued after July 4, 2025. Pre-OBBBA stock retains the prior tiered rates (50/75/100% at the same holding periods). At 100% exclusion, an employee with $15M in C-corp stock at exit pays zero federal capital gains tax and zero NIIT. Compare that to phantom equity: at 37%, the same employee would owe $5.55M in ordinary income tax on a $15M payout.

Pre-sale planning: what to do before you're in a deal

If you have phantom equity outstanding and are 2+ years from a sale

Converting phantom equity to real equity — profits interests (LLC) or restricted stock + §83(b) (C-corp) — before the company's value increases substantially is the highest-value planning move available. The conversion works best when:

• The company's current fair market value is low enough that the new grant starts with a small ordinary income hit
• There is enough time for the one-year (or five-year, for QSBS) holding period to run before a sale
• The phantom equity plan can be amended or replaced by mutual agreement (employees typically agree, since they improve their tax position)

A conversion too close to a sale raises two risks: (1) the holding period won't be satisfied, (2) IRS step-transaction arguments could recharacterize the LTCG as ordinary income if the conversion and sale are viewed as a single planned event. Most advisors require 12–18 months between conversion and closing to have a defensible position.

If you are still in design mode (haven't issued equity yet)

Choose real equity over phantom equity when the goal is retention over multi-year horizons and the employee is comfortable with actual ownership obligations. The primary reasons to use phantom equity over real equity are: (1) you want to avoid actual ownership dilution; (2) your entity is a C-corp and the QSBS criteria will not be met; (3) administrative simplicity. If those reasons don't apply, profits interests (LLC) or restricted stock + §83(b) (C-corp) produce materially better tax outcomes for recipients at no additional cost to you — and often improve retention by creating an ownership culture.

Verify §409A compliance on existing phantom equity plans

Before going to market, have your compensation attorney review all phantom equity documents for §409A compliance. Specific areas to check:

• Does "change in control" meet the §409A definition (80%+ ownership threshold, asset purchase meeting the 409A test, board change test)?
• Are payment mechanics specified (date of payment, form of payment)?
• Were any elections or amendments made outside the permitted timing windows?

A §409A defect discovered after LOI is signed is expensive to correct and can affect deal pricing. Buyers typically require clean §409A representations in reps-and-warranties. See: Representations and Warranties Insurance Guide.

If you're already in a deal with phantom equity outstanding

At LOI or later, your options to convert phantom equity have largely closed. Focus on deal mechanics:

1. Model the net proceeds impact accurately

Your gross purchase price is not your net proceeds. Subtract: (a) the total phantom equity pool at the deal price, (b) employer FICA on the payout, (c) any §409A gross-up obligations in the plan documents. Build this into your post-sale financial planning model before closing. See: Retirement Readiness Calculator.

2. Negotiate who bears the employer FICA

In some deals, the buyer agrees to absorb the employer FICA cost because the phantom equity plan is effectively a company liability that transfers with the business. In others, the seller funds it from the purchase price. This is a point in deal negotiations — know your position before the wire instructions are set.

3. Ensure payroll processing is set up for closing-day phantom equity payments

Phantom equity payouts are processed through payroll, not as a distribution. This means payroll runs on or around the closing date, withholding is computed, W-2s or W-2c forms are filed, and the employer remits FICA. If your payroll provider is not prepared for a large, non-routine payroll event at closing, get them briefed early. Errors in FICA calculation or failure to withhold properly create post-close tax problems for both the company and the employees.

4. Inform phantom equity holders of their expected tax impact in advance

Employees who discover at closing that their $500K phantom equity payout becomes $315K after ordinary income tax are rarely happy, even if the plan documents were legally correct. Proactive communication — a simple spreadsheet showing gross payout, expected withholding, and net — prevents the post-close surprise and preserves relationships, particularly if you're staying on for a transition period.

Together these establish the safe harbor for profits interests: no income recognition at grant if the three conditions are met (entity not publicly traded; no disposition within 2 years; not an interest in a publicly traded partnership). Rev. Proc. 2001-43 clarifies that unvested profits interests meeting the 93-27 conditions are also excluded from income at grant.

Profits interests under Rev. Proc. 93-27 are treated as having zero FMV, so §83(b) elections on profits interests typically produce zero ordinary income at grant.

ATB is defined as raising/returning capital plus investing/disposing of specified assets (securities, commodities, real estate, etc.). Operating businesses — manufacturing, technology, retail, professional services — do not constitute ATBs; profits interests in operating companies are not APIs subject to the 3-year holding period.

OBBBA (One Big Beautiful Bill Act, July 2025) increased the per-taxpayer exclusion to $15M (10× basis) with tiered holding (50/75/100% at 3/4/5 years) for stock issued after July 4, 2025.
