A SAR ESOP is a deferred compensation plan that pays employees cash equal to the increase in the company’s stock value over time, without ever handing them actual shares. The name is a little misleading. Unlike a traditional employee stock ownership plan, a stock appreciation rights ESOP holds no company stock in trust. It borrows the ESOP framework (vesting schedules, independent valuations, defined payout events) and applies it to a contractual promise that tracks share price appreciation. Employees get an ownership-like payout. The company keeps its cap table untouched.
How the Payout Actually Works
A SAR is a contract. The company grants an employee a set number of hypothetical shares at a fixed strike price, and when the SAR is later settled, the employee receives cash equal to the appreciation over that strike price. If the strike is $50 and the shares are worth $80 when the employee cashes out, the employee gets $30 per SAR. No purchase, no equity, no voting rights, no capital at risk.
Because the plan holds no real stock, it does not dilute existing shareholders. That structural fact is what separates a SAR ESOP from a traditional ESOP, where a trust actually buys and holds company shares for the benefit of employees.
Grant, Vesting, and Settlement
The life of a SAR runs through three stages.
Grant
On the grant date, the employee is assigned a specific number of SARs and the strike price is locked in. That strike price is almost always the current fair market value of the stock, set by an independent appraiser. At the moment of grant the SAR is worth nothing, because the spread between strike and current value is zero. Setting the strike at FMV is not just customary. It is a Section 409A compliance requirement, and granting below FMV creates immediate tax problems for the employee.
Vesting
The vesting schedule decides when the employee’s rights become exercisable. SAR plans are nonqualified, so the company has wide latitude in designing it. Cliff vesting holds everything back until a set date and then releases it all at once. Graded vesting releases a portion each year. The choice usually tracks the company’s retention goals. Many plans also accelerate vesting on a change in control, so employees keep the benefit they earned if the business is sold.
Payout
When a SAR is exercised or a triggering event occurs, the appreciation is calculated as (current FMV − strike price) × number of SARs. An employee holding 5,000 SARs with a $20 strike, cashing out at an FMV of $45, receives $125,000. The current FMV must come from a fresh independent appraisal, not an estimate. Most plans settle in cash, and the plan document must spell out the settlement method in advance because it drives tax timing.
Why S-Corporations Reach for This Structure
S-corporations operate under strict ownership rules. They cannot have more than 100 shareholders, cannot have partnerships or corporations as shareholders, cannot have nonresident alien shareholders, and are limited to a single class of stock.1Office of the Law Revision Counsel. 26 U.S. Code 1361 – S Corporation Defined Issuing real shares to an ESOP trust risks colliding with the shareholder cap or the single-class-of-stock rule.
SARs sidestep those constraints. Because they are contractual rights and not equity, holders are not shareholders for tax purposes. The company can extend ownership-like incentives to hundreds of employees without adding a name to the register or jeopardizing its S-corporation election.2Internal Revenue Service. S Corporations
Section 409A: The Rules That Govern Everything
Section 409A of the Internal Revenue Code governs nonqualified deferred compensation, and SAR ESOPs sit squarely inside it. Two pieces of 409A matter most.
When Payouts Are Allowed
A SAR plan can only distribute benefits on one of six triggering events:3eCFR. 26 CFR 1.409A-3 – Permissible Payments
- Separation from service
- Disability, as defined by the plan
- Death
- A fixed date or schedule set at the time of the deferral election
- Change in control of the company
- Unforeseeable emergency causing severe financial hardship
If a plan allows any other trigger, or lets the employee freely choose the timing, the whole arrangement fails 409A. The payment trigger has to be locked in when the deferral is first elected.
Strike Price at Fair Market Value
SARs must be granted at or above the stock’s FMV on the grant date. For a private company, the safest way to establish that value is an independent third-party appraisal, which creates a presumption of reasonableness that shifts the burden of proof to the IRS if the valuation is challenged.4eCFR. 26 CFR 1.409A-1 – Definitions and Covered Plans
The Penalties Fall on the Employee
When a plan violates 409A, the tax consequences hit the participant, not the company. All deferred compensation under the noncompliant arrangement becomes taxable the moment it vests. On top of that, the employee owes a 20% excise tax on the included amount, plus interest at the underpayment rate plus one percentage point running back to the original year of deferral.5Office of the Law Revision Counsel. 26 U.S. Code 409A – Inclusion in Gross Income of Deferred Compensation Under Nonqualified Deferred Compensation Plans On a large payout, those combined penalties can eat a serious slice of the benefit.
Tax Treatment for the Employee
The grant is not a taxable event. Vesting alone does not trigger income tax either. Tax hits when the cash is actually paid. At that point the full appreciation is ordinary income, reported on Form W-2, and subject to federal income tax withholding at the employee’s rate.
No Section 83(b) election is available. That election applies to transfers of property, and a SAR transfers no property at grant. Employees should plan for a large tax year when a payout arrives, since the appreciation can pile onto ordinary income all at once.
FICA Has Its Own Timing Rule
SAR payouts are subject to Social Security tax (6.2% up to the annual wage base) and Medicare tax (1.45% on all earnings).6Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates For 2026, the Social Security wage base is $184,500.7Social Security Administration. Contribution and Benefit Base Medicare has no cap, and employees earning more than $200,000 in a calendar year owe an additional 0.9% Medicare surtax on wages above that amount.8Internal Revenue Service. 2026 General Instructions for Forms W-2 and W-3
Here is the quirk. Nonqualified deferred compensation follows a special FICA timing rule: FICA is due at vesting, not at cash payout. If SARs vest in 2026 but pay out in 2029, the employer should withhold FICA in 2026 on the value at vesting. A nonduplication rule then prevents the same amount from being hit with FICA again when the cash finally moves. The practical effect is that FICA comes due sooner than employees expect, and the employer needs a way to estimate the deferred value at vesting even though the final payout figure is not yet known.
Tax Treatment for the Employer
The company gets a compensation deduction equal to the ordinary income the employee recognizes, in the employer’s taxable year that lines up with when the amount is included in the employee’s gross income.9Office of the Law Revision Counsel. 26 U.S. Code 404 – Deduction for Contributions of an Employer to an Employees Trust or Annuity Plan and Compensation Under a Deferred-Payment Plan Pay a $200,000 SAR appreciation, deduct $200,000 in the corresponding period.
One catch that is easy to miss: the statute requires the company to maintain separate accounts for each participating employee. Without individual account tracking, the deduction is not available. That bookkeeping detail is small in effort and expensive to get wrong.
ERISA and the Top-Hat Filing
Whether the plan falls under ERISA depends on who participates. A broad-based plan can be classified as an employee pension benefit plan subject to ERISA’s full participation, vesting, funding, and fiduciary rules. Most SAR ESOPs are designed to avoid that outcome by covering only a select group of management or highly compensated employees. A plan that fits this description is a “top-hat” plan and is exempt from those ERISA rules.
For 2026, the IRS defines a highly compensated employee as one earning more than $160,000 in the preceding year.10Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living
Even with the top-hat exemption, the company must file a short statement with the Department of Labor within 120 days of adopting the plan. The filing includes the employer’s name and address, EIN, a declaration that the plan covers a select group of management or highly compensated employees, and the number of employees covered. It must be submitted electronically.11eCFR. 29 CFR 2520.104-23 – Alternative Method of Compliance for Pension Plans for Certain Selected Employees Missing the deadline does not automatically disqualify the plan, but it forfeits the simplified reporting safe harbor and can attract regulatory attention.
Annual Valuation: The Engine of the Plan
Every grant needs a defensible strike price. Every payout needs a current FMV. Both figures should come from a qualified independent appraiser using a reasonable valuation method. For a typical closely held company, annual appraisal costs run roughly $1,500 to $9,000, depending on the complexity of the business, the number of entities, and the appraiser’s market. That cost recurs every year the plan is active. A poorly supported valuation invites IRS challenges on both 409A compliance and the reasonableness of the compensation deduction, so cutting corners here rarely pays off.
The Risk Participants Should Understand
Here is the piece that participants often miss until it matters. For a top-hat plan to keep its ERISA exemption, benefits have to be paid solely from the employer’s general assets.11eCFR. 29 CFR 2520.104-23 – Alternative Method of Compliance for Pension Plans for Certain Selected Employees The plan must stay unfunded. Nothing is set aside in a segregated account that belongs to the employee. When the payout date arrives, the company writes a check from its operating funds.
If the company runs into financial trouble or files for bankruptcy before that check clears, SAR participants stand in line as unsecured creditors alongside trade creditors and lenders. They get no priority. In the worst case they receive nothing, and this has happened to employees at companies that have gone through bankruptcy with nonqualified deferred compensation on the books.
Some companies establish rabbi trusts to informally earmark assets for future SAR obligations. A rabbi trust gives participants visibility that the money exists, but the assets remain reachable by the company’s general creditors in bankruptcy. If the trust were truly creditor-protected, the plan would be considered funded, which would blow up the top-hat exemption and the favorable tax deferral. Anyone weighing a SAR ESOP should measure the value of the benefit against the financial strength of the company standing behind it.
