A long-term incentive plan, or LTIP, is an employer pay program that ties part of your compensation to multi-year performance or continued employment, usually delivered through equity awards such as restricted stock units, performance shares, or stock options. A typical grant spans three to five years before it pays out, which is the entire design intent: your financial interest stays locked to the company’s long-term results. What the award is actually worth to you comes down to three things — how it vests, how it’s taxed, and what happens if you leave before it matures.
The Award Types You Might Receive
Most plans use one or a mix of four instruments, and they behave very differently.
Restricted stock units (RSUs) are a promise to deliver a set number of shares on a future date. You don’t own the shares yet, and you get no votes or dividends until they land in your brokerage account. RSUs are the most common LTIP vehicle at large public companies because they always keep some value as long as the stock price stays above zero.1Practical Law. Restricted Stock Unit (RSU)
Performance shares work like RSUs, but the number of shares you ultimately receive depends on the company hitting specific financial or market targets over a multi-year measurement period. Miss the goals and you might receive a fraction of the original grant, or nothing.
Stock options give you the right to buy shares at a locked-in strike price set on the grant date. You profit only if the market price climbs above that strike. Options come in two tax categories, incentive stock options and non-qualified stock options, with meaningfully different consequences.
Stock appreciation rights (SARs) pay you the increase in stock price above your grant price without requiring you to spend cash on shares. The company simply pays the difference in cash or shares when you exercise.
Some plans also credit dividend equivalents on unvested RSUs or performance shares, paid out with the underlying award and taxed as ordinary income rather than as qualified dividends.
How Vesting Works
Vesting is what turns a promise into ownership. Until an award vests, you can’t sell it, transfer it, or count on keeping it if you leave. Plans generally use one of two time structures, often layered with performance conditions.
Cliff Vesting
With a cliff schedule, nothing vests until a single date arrives, at which point the entire grant vests at once. A three-year cliff means zero ownership through year two and 100% on the third anniversary. The retention pull is strong, and so is the penalty for leaving one month early.
Graded Vesting
Graded schedules release the award in installments, commonly 25% per year over four years. You accumulate value gradually and keep whatever has already vested if you leave mid-cycle.
Performance and Market Conditions
Many grants add performance triggers on top of the time requirement. Internal metrics like earnings per share or revenue growth are common; miss them during the measurement period and part or all of the award expires worthless. Market conditions like total shareholder return relative to a peer index depend on external stock movement rather than internal accounting, but from your side the practical effect is the same: the payout depends on hitting the target.
Who Gets an LTIP and How the Size Is Set
Eligibility was once limited to top executives, but many companies now extend LTIP grants to senior managers, directors, and employees identified as critical to long-term strategy. HR departments typically use standardized job grades to decide who receives a grant and how large it is.
Grant sizing usually starts with a target percentage of base salary. A senior manager might receive an award valued at 40% to 60% of annual pay, while a senior executive could receive 150% or more. Individual performance ratings adjust the final number, and the dollar value is then converted into a share count or option count based on the stock price on the grant date.
What You Owe in Taxes When the Award Vests
This is where most recipients get surprised. When RSUs or performance shares vest, the IRS treats the fair market value of those shares as ordinary income for that tax year, even if you don’t sell a share.2Internal Revenue Service. Topic No. 427, Stock Options The income appears on your W-2 and is subject to federal income tax, state income tax where applicable, Social Security, and Medicare.
Federal Income Tax
LTIP payouts are classified as supplemental wages for withholding. Your employer withholds a flat 22% on the first $1 million of supplemental wages paid during the calendar year, and 37% on any amount above $1 million.3Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide That 22% is only withholding. If a large vest pushes your total income into the 32% or 35% bracket, you’ll owe the difference when you file. The top federal rate of 37% applies to taxable income above $640,600 for single filers and $768,600 for married couples filing jointly in 2026.4Tax Foundation. 2026 Tax Brackets and Federal Income Tax Rates
Social Security and Medicare
Vesting also triggers FICA. In 2026, Social Security tax applies at 6.2% on earnings up to $184,500.5Social Security Administration. Contribution and Benefit Base If your base salary already exceeds that cap by the time shares vest, no additional Social Security tax applies to the LTIP income. Medicare tax of 1.45% applies to all earnings with no cap, and an additional 0.9% Medicare surtax kicks in on earnings above $200,000 for single filers or $250,000 for married filing jointly.
How the Withholding Gets Paid
Because you owe tax on shares you haven’t sold, the employer needs a way to collect cash. The most common method is sell-to-cover: the company sells enough of your newly vested shares to pay the withholding and deposits the rest in your brokerage account. Some plans use net settlement, where the company simply withholds a portion of the shares and delivers fewer to you. Either way, the number of shares you actually receive is smaller than the grant number.
Stock Options as a Special Case
Options in an LTIP fall into one of two categories, and the tax gap between them is wide.
Non-Qualified Stock Options (NSOs)
When you exercise an NSO, the spread between the market price and your exercise price is taxed immediately as ordinary income, whether you hold or sell the shares.2Internal Revenue Service. Topic No. 427, Stock Options That spread is supplemental wages, subject to the 22% flat withholding rate (37% above $1 million).3Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide FICA applies as well. Any additional appreciation after exercise is taxed under capital gains rules based on how long you hold the shares.
Incentive Stock Options (ISOs)
ISOs get preferential treatment if you meet two holding requirements: you must hold the shares at least two years after grant and at least one year after exercise.2Internal Revenue Service. Topic No. 427, Stock Options Meet both, and the entire gain from exercise price to sale price is taxed as long-term capital gain. Miss either deadline and you’ve made a disqualifying disposition, which reclassifies the spread at exercise as ordinary income.
The catch is the Alternative Minimum Tax. The ISO spread at exercise isn’t taxed for regular income tax purposes, but it is a preference item for AMT.2Internal Revenue Service. Topic No. 427, Stock Options For 2026, the AMT exemption is $90,100 for single filers and $140,200 for married couples filing jointly, with phase-outs starting at $500,000 and $1,000,000 respectively.6Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 A large ISO exercise can blow through that exemption and trigger AMT even though you haven’t sold anything. AMT paid becomes a credit usable in future years when regular tax exceeds AMT.
What You Owe When You Sell the Shares
Once RSUs or performance shares vest, or once you exercise options, your cost basis is the fair market value on the vesting or exercise date. Any change in value from that point forward is a capital gain or loss. Sell within a year and the gain is short-term, taxed at ordinary income rates. Hold more than a year and long-term capital gains rates apply.7Internal Revenue Service. Topic No. 409, Capital Gains and Losses
For 2026, long-term capital gains rates are 0%, 15%, or 20% depending on taxable income. Most LTIP recipients land in the 15% bracket, with 20% applying to single filers above $545,500 and married couples filing jointly above $613,700.4Tax Foundation. 2026 Tax Brackets and Federal Income Tax Rates High earners also face the 3.8% Net Investment Income Tax on capital gains once modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married filing jointly, pushing the effective top rate to 23.8%.8Internal Revenue Service. Net Investment Income Tax
A common trap is letting employer stock quietly become the largest holding in your portfolio. Once shares vest and the income tax is paid, the decision to keep them should rest on whether you’d buy that stock today at its current price.
One boundary worth flagging: the Section 83(b) election, which lets you pay tax on the grant-date value of a restricted stock award rather than waiting for vesting, applies only to actual restricted stock. It does not apply to RSUs, which are the standard LTIP vehicle, because RSUs don’t transfer property to you until vesting.9Office of the Law Revision Counsel. 26 U.S. Code 83 – Property Transferred in Connection With Performance of Services
What Happens if You Leave Before Vesting
This is where LTIPs function as golden handcuffs. The default rule at most companies is simple: if you resign voluntarily or are terminated for cause, all unvested awards are forfeited. You walk away with nothing from grants that haven’t vested, no matter how close the next vesting date sits. This is usually the single biggest financial consideration in a mid-cycle job change.
Other kinds of exit are often treated differently, though specifics vary by plan:
- Retirement often triggers pro-rata vesting for awards held at least a year, based on how much of the vesting period you completed.
- Death or disability frequently produces accelerated or pro-rata vesting, though performance conditions may still have to be satisfied.
- Involuntary termination without cause varies widely. Some plans provide pro-rata vesting; others forfeit everything just as a resignation would.
Read your plan’s termination provisions before making any career move. The difference between leaving on June 30 and July 1 can be worth a full year of salary if a vesting tranche falls on July 1.
What Happens if the Company Is Acquired
When your employer is acquired, treatment of unvested awards depends on whether the plan uses single-trigger or double-trigger acceleration.
Single-trigger acceleration means the acquisition itself vests everything. You get your shares or cash payout at closing. Employees like it; acquirers generally don’t, because they want unvested equity holding key people in place through the transition.
Double-trigger acceleration requires two events: the acquisition plus a qualifying termination, usually being fired without cause or resigning for “good reason” (a significant pay cut, forced relocation, or major demotion) within a specified window after closing, commonly 9 to 18 months. Stay employed through the transition and your awards continue vesting on the original schedule under the new owner. Double-trigger protects you from being pushed out post-close without protecting a voluntary exit.
One subtlety: double-trigger only works if the acquirer actually assumes or continues your unvested awards. If the acquisition agreement cancels outstanding equity and pays out only the vested portion, no unvested awards remain to accelerate later. Read the deal language carefully during any acquisition announcement.
Clawbacks After the Money Is Paid
Even after an LTIP has vested and paid out, you may not be fully clear. Under rules implementing Section 10D of the Securities Exchange Act, publicly traded companies must maintain a clawback policy requiring recovery of incentive-based compensation from current or former executive officers if the company is required to restate its financial results. The clawback reaches back three years before the restatement date and covers the amount that exceeds what would have been paid under the corrected numbers.10U.S. Securities and Exchange Commission. Recovery of Erroneously Awarded Compensation
Companies that fail to adopt or enforce a compliant policy face delisting. For employees, the practical takeaway is that performance-based LTIP payouts tied to financial metrics carry residual risk for several years after vesting. If the numbers that drove your payout were wrong, the company has a legal obligation to come collect the difference.
