Restricted stock units (RSUs) are a company's promise to deliver shares once you meet specific conditions, usually staying employed for a set period. Think of it as a paycheck held in escrow until you've earned it on the company's timeline.
Restricted stock units are not shares when granted, unlike other forms of equity compensation. Restricted stock units are a contractual obligation from your employer to deliver shares or their cash value at a future date. Until that date, you have no voting rights, no dividends, and no ability to sell. You can't transfer them, and if you leave before they vest, you forfeit them entirely.
That forfeiture clause is the whole point. The restriction is a retention mechanism by design.
For business owners, restricted stock units let you compete on total compensation without depleting cash. For employees, they can represent a meaningful wealth-building vehicle if you understand the rules before you vest.
Replacing a skilled employee costs between 50% and 200% of their annual salary, depending on the role. Restricted stock units give companies a way to reduce that cost by tying a portion of compensation to tenure.
Companies that can't always match big-company salaries use restricted stock units to make their total compensation packages more enticing. The equity delivers value as the company grows, which aligns the employee's financial outcome directly with the company's performance. That alignment is harder to fake and harder to leave behind.
From a cash perspective, restricted stock units also let you pay people in future equity rather than today's dollars, which preserves runway during growth stages.
Large technology and finance companies with stable valuations issue restricted stock units broadly, well beyond the executive level. Amazon, Google, Meta, and Microsoft all include restricted stock units in offers for engineers, product managers, and sales professionals at multiple seniority levels.
McDonald's is a well-documented public example. Their SEC-filed RSU grant terms show a standard three-year vesting period from the grant date, with pro-rata vesting provisions for long-tenured employees who retire or are terminated without cause. The filing also outlines how payout happens within 90 days of the vesting date, in shares or cash at the company's discretion.
Later-stage private companies have also embraced restricted stock units, particularly in tech. The challenge for private companies is that employees receive shares they often can't sell until an acquisition or IPO. That liquidity gap shapes almost every other RSU decision a private company makes.
Understanding how restricted stock units work requires unpacking three stages: the grant, the vest, and the settlement. Each stage has different rules and different financial consequences.
The most common structure is a four-year vesting schedule with a one-year cliff. You earn nothing during year one, then receive shares in quarterly or monthly increments. A grant of 1,200 restricted stock units vesting over four years might deliver 300 in year one, then 25 per month after that.
Some restricted stock units include performance conditions. You receive shares only if the company hits specific financial targets (like earnings per share goals) in addition to the time requirement. These performance-based restricted stock units are common for senior executives and are increasingly appearing in mid-level roles.
For private companies, the trigger structure matters enormously. Double-trigger restricted stock units require two conditions: time-based vesting AND a liquidity event like an acquisition or IPO. You don't owe taxes until both conditions are met, which protects employees from a cash tax bill on shares they can't sell.
Single-trigger restricted stock units vest on time alone. They're rare in private companies specifically because vesting without a public market creates a serious problem: you owe taxes immediately, in cash, on stock you can't liquidate. Ask your employer which structure you're getting before you sign an offer letter.
Once restricted stock units vest, the company delivers shares to your brokerage account or pays the cash equivalent of that share value. Most public companies settle in shares. The company typically decides whether payout is in shares or cash, though some plans give you input.
The differences between restricted stock units, stock options, and restricted stock awards affect your tax outcome, your ownership timing, and your exposure to downside risk. Here's how they stack up.
When comparing restricted stock units and stock options, the core difference is risk. Stock options pay off only if the share price rises above the strike price. Restricted stock units always have value at vesting as long as the company's stock is worth anything because you receive shares outright rather than the right to buy them.
That's why companies typically move from stock options to restricted stock units as they scale. On average, this shift happens about 5.5 years after incorporation when option grants become harder to value and exercise.
When comparing restricted stock units and restricted stock awards, the decisive factor is the 83(b) election. With restricted stock awards, you own the shares at grant and can elect to pay ordinary income tax on their value immediately at the current fair market value. If the company is early-stage and shares are nearly worthless, that tax bill is tiny. Any future appreciation is taxed at the lower capital gains rate.
Restricted stock units don't allow an 83(b) election. You pay ordinary income tax when shares vest, based on the fair market value that day. For a company that has grown significantly, this can be a much larger tax bill than an 83(b) election years earlier.
Designing a restricted stock unit plan without legal guidance is a fast way to trigger IRS penalties. Three regulatory frameworks matter most.
Section 409A of the Internal Revenue Code governs nonqualified deferred compensation, and restricted stock units fall within its scope. The rule requires restricted stock units to vest and settle simultaneously or that any deferred settlement follow strict timing rules. Violating Section 409A results in immediate income inclusion of the full deferred amount plus a 20% excise tax penalty on top of regular income taxes. This combination is painful and avoidable with proper plan design and legal review.
Restricted stock unit grants to executives at public companies trigger reporting requirements under Section 16 of the Securities Exchange Act of 1934. Insiders must report grants on Form 4 within two business days. Companies also disclose outstanding grants in their annual Form 10-K and proxy statement (DEF 14A). If you're a company officer receiving restricted stock units, your transactions are public record.
Private companies typically rely on SEC Rule 701 or Regulation D to exempt employee equity grants from registration requirements, but both exemptions carry disclosure thresholds and dollar limits. Beyond federal rules, states like California maintain their own securities frameworks that apply to grants made to California residents. If your workforce spans multiple states, your plan documents need jurisdiction-specific review.
Restricted stock units are taxed as ordinary income at vesting. The IRS treats the fair market value of vested shares as wages, which means those dollars show up on your W-2 and are subject to federal income tax, state income tax, and payroll taxes including Social Security and Medicare.
For 2025, how are restricted stock units taxed at the federal level? The rate can reach 37% for high earners. Employers withhold at the IRS supplemental wage rate: 22% on the first $1 million in supplemental income and 37% above that. But if your marginal tax rate is higher than 22%, the withholding won't cover your full liability. You'll owe the difference when you file, and that gap surprises a lot of people in their first RSU vesting year.
Once shares land in your account, the clock resets. Any appreciation from that point is a capital gain, not ordinary income. Per IRS Topic 409, long-term capital gains rates for 2025 are 0%, 15%, or 20% depending on your taxable income. Hold shares more than one year after vesting to qualify for the lower rate. Sell the day your shares vest and you'll likely owe little to no additional capital gains tax since the sale price and vesting-day fair market value are nearly identical.
If you hold single-trigger restricted stock units in a private company, taxes come due at vesting even though you can't sell the shares to cover the bill. You're paying cash taxes on equity with no current liquidity. The IRS only accepts cash. This is why most private companies use double-trigger restricted stock units or allow share withholding to cover tax liability at vesting.
Allowing employees to sell vested restricted stock units is a strategic decision, not just an administrative one. The answer depends on your company stage, cap table goals, and how you want equity to function as a retention tool.
The argument for allowing sales is straightforward: equity employees can access feels like real compensation. If equity is permanently locked up, it feels like a lottery ticket; nice in theory, useless in practice. That perception erodes its retention value faster than expected.
But allowing open secondary sales has downsides. Each transfer requires legal review, company consent, and often a right-of-first-refusal process. Uncoordinated sales can introduce new outside shareholders and complicate your cap table. In public markets, it can put downward price pressure if many employees sell simultaneously.
For most growth-stage private companies, a structured tender offer program is a better approach. You set the timeline, control the price, define who can participate, and give employees real liquidity without opening the door to unpredictable secondary transactions. Public companies manage this through formal trading windows and insider trading policies.
The process for selling restricted stock units depends on whether your company is public or private. Both paths involve rules you need to understand before acting.
Once your restricted stock units vest and shares appear in your brokerage account, you can generally sell them on the open market immediately, subject to your company's trading policy. Most public companies restrict trading to designated open windows, typically the period following quarterly earnings announcements, to prevent insider trading violations.
If you're an executive or director, SEC Rule 144 and Section 16 reporting apply to your transactions. Non-insiders have more flexibility but should still review company policy. Some companies also have mandatory post-vesting holding requirements for senior employees.
Double-trigger restricted stock units in a private company can't be sold until both vesting conditions, including the liquidity event, are met. There's nothing to sell yet since shares haven't been issued.
If you hold vested private company shares following a single-trigger vest or a company-run tender offer, secondary marketplaces offer a path to liquidity. Platforms like Acquire.Fi and Nasdaq Private Market facilitate privately negotiated transactions, though minimum ticket sizes typically start at $50,000 to $10,000,000. The company typically has a 30-day right of first refusal before any outside buyer can complete the purchase. Check your stock plan documents and get written company approval before pursuing any secondary sale.
If you want exposure to a private company's equity without being an employee, you can sometimes purchase shares on the secondary market after an employee's restricted stock units have vested and converted into common stock. This is genuinely complex, requires company approval, and involves meaningful risk. Private shares are illiquid, have no guaranteed exit timeline, and typically carry rights restrictions.
Secondary marketplace platforms, like Acquire.Fi, enable investors to buy pre-IPO equity positions, including common stocks and RSUs from private companies. Minimum investment thresholds are typically $500,000 or higher and require accredited investor status. Understand the company's cap table, its last 409A or funding round valuation, and any transfer restrictions before committing capital.
Restricted stock units are simultaneously simpler and more nuanced than most people realize. Simpler because the core mechanic is straightforward: stay employed, meet the conditions, get the shares. More nuanced because the tax rules, vesting structures, and liquidity constraints vary significantly by company stage and plan design.
If you're a business owner building a compensation plan, get legal and tax counsel before finalizing your plan documents. The Section 409A and securities law risks are real, and the cost of getting it wrong is steep.
If you're an employee evaluating an offer with restricted stock units, push for the 409A valuation, ask whether vesting is single or double trigger, and model the tax impact before you anchor to the headline grant number.
