It often begins with a simple notification. A message from your company’s equity portal. A note from HR. A reminder that a long-awaited vesting date has arrived. On paper, your net worth just increased. Then, a few weeks later, another realization appears. A sizable tax withholding. Fewer shares than expected deposited into your account. A new entry on your W-2.

For many executives and high-earning professionals, equity compensation is familiar. The tax mechanics behind it are often less so. And misunderstanding them can lead to unnecessary surprises. This blog explains what happens when restricted stock units vest — and how a closely related form of equity, restricted stock awards, differs.

RSUs: a promise of future shares

Restricted stock units (RSUs) are a contractual promise to deliver company shares at a future date, assuming certain conditions are met — typically continued employment over time. Before vesting, RSUs are not actual shares. They are an agreement. At vesting, that agreement converts into stock you own. That conversion moment is where taxation begins…

When RSUs vest, the fair market value of the shares delivered is treated as ordinary income. The amount appears on your W-2 and is taxed similarly to salary or bonus compensation. If 1,000 shares vest at $50 per share, $50,000 of ordinary income is recognized — regardless of whether you sell the shares immediately or continue holding them.

This distinction matters. Many executives assume taxes arise only when shares are sold. With RSUs, taxation begins at vesting.

 Why your company withholds shares

Because RSU income is treated as compensation, your employer is required to withhold payroll taxes. Most companies satisfy this requirement by selling or retaining a portion of the newly vested shares. The remaining shares are deposited into your brokerage account. The result is often a smaller net share delivery than expected. It isn’t a penalty. It’s simply payroll withholding applied to equity income rather than cash compensation.

A second tax event happens later

Once RSUs vest, you own company shares with a cost basis equal to the market value at vesting. If you sell later at a different price, you’ll realize a capital gain or loss. How long you hold the shares determines whether that gain is short-term or long-term.

This second layer of taxation is easy to overlook, yet it can meaningfully influence after-tax outcomes — particularly when large vesting schedules repeat year after year.

A quick note on restricted stock awards (RSAs)

Some executives — particularly founders or employees at earlier-stage companies — may encounter restricted stock awards (RSAs) instead of RSUs.

The distinction is subtle but important. With RSAs, actual shares are issued at grant, but they remain subject to forfeiture until vesting conditions are met. In contrast, RSUs deliver shares only at vesting. This structural difference changes the tax timing. RSAs may be taxed at vesting — similar to RSUs — or, in certain cases, an employee may elect to recognize income at grant instead This is what’s known as an 83(b) election, which carries trade-offs and is highly situational.

For most executives at established companies, RSUs remain the more common structure. But understanding that both forms exist helps clarify why equity compensation can look different from one employer to another.

Concentration risk quietly builds

Equity compensation has a subtle side effect. Over time, it increases exposure to your employer’s stock — often without an explicit decision to do so. Your income, career, benefits, and investment portfolio may all become linked to the same company. Whether that concentration aligns with your broader financial plan is a question worth revisiting periodically.

Planning considerations

Equity compensation is not inherently good or bad. It is simply a form of pay — one that introduces complexity that traditional salary does not.

Some considerations that often matter:

• How equity income affects your overall tax picture
• Whether withholding is sufficient
• How much employer stock fits your desired investment allocation
• Whether to hold or sell shares as they vest
• How upcoming vesting events align with cash-flow needs

There are no universal answers. But proactive awareness tends to create better outcomes than reactive decisions.

Why timing matters

Vesting schedules are predictable. That predictability creates opportunity for planning. Tax projections can be modeled ahead of time. Portfolio exposure can be monitored before concentration becomes excessive. Liquidity needs can be anticipated rather than improvised. In wealth planning, clarity is usually more valuable than urgency.

A closing thought

Equity compensation can accelerate wealth creation. It can also introduce complexity that traditional pay does not. Understanding when equity becomes income — and what happens next — transforms stock awards from a confusing benefit into a manageable part of your financial life.

Not by chasing outcomes. Simply by replacing uncertainty with structure.
