Restricted Stock Units (RSUs) are a future promise of stock-based compensation offered to employees as part of their total benefits package. While RSUs are an excellent addition to your financial arsenal, they may have significant tax ramifications. It is important to understand how RSUs work and where they fit into your overall financial plan.
Vesting
When RSUs are first granted, they are only a promise. Your employer is promising shares of company stock in the future. This is done through a vesting schedule. Once RSUs vest, they’re considered part of your taxable income. You take ownership of the shares and can decide how to use them.
Each grant of RSUs has its own vesting schedule. A vesting schedule is an incentivized, time-based carrot. It’s a way your employer encourages you to remain a long-term employee. Vesting schedules are primarily either graded or cliff.
Graded vesting: A predetermined percentage of your RSU award will vest after each year of service.
Example — Graded Vesting
You were granted 4,000 RSUs on 12/15/2023. Your graded vesting schedule spans five years, and 20% of the grant vests yearly. On each anniversary of your grant date for five years, 800 shares will vest.
Most graded vesting schedules play out over three to five years on a consistent schedule. Occasionally, though, the intervals between vesting dates aren’t equal. Some portions vest sooner, others later.
Example — Graded Vesting (Varying Schedule)
You were granted 6,000 RSUs on 12/15/2023. Three years after the grant date, 60%, or 3,600 shares, vest. The remainder, 2,400 shares, vest 2 years later.
Cliff vesting: 100% of your RSUs vest after a specific time.
Example — Cliff Vesting
You were granted 5,000 RSUs on 12/15/2023. Five years after the grant date — 12/15/2028 — 100% of the shares vest all at once.
What happens if you quit your job or are let go? You lose your RSUs. The only exceptions to vesting are death or disability, in which case vesting may be allowed to continue or even accelerated. Retirement is usually not an exception, but check your employer’s RSU plan documents to verify.
RSUs Tax Treatment
First and most importantly, RSUs are treated and taxed as earned income in the tax year they vest. The taxable amount is the current fair market value of your shares on the vesting date. They will appear on your W-2 and include the following:
- Federal taxes
- Employment taxes
- Social Security & Medicare
- State and Local taxes
Example — Taxable Income at Vesting
You have 800 shares that just vested. The stock price on the vesting date was $20.
800 shares × $20 = $16,000 of taxable compensation added to your W-2.
Problems arise when many shares vest and the stock price is significantly higher.
Example — Large Vest & Tax Impact
You have 2,000 shares that just vested. The stock price on the vesting date was $120.
2,000 shares × $120 = $240,000 of taxable compensation. Yes, that’s a great problem to have — but remember, you owe ordinary income taxes on every dollar of it.
Yes, that’s an excellent problem, but there are tax ramifications. Remember, you have to pay earned income taxes on that compensation!
⚠️ Watch Out — The Default 22% Withholding Trap
Many companies automatically withhold taxes on RSU vesting at a flat 22% federal rate. If you’re in the 32%, 35%, or 37% tax bracket, that shortfall can add up fast and leave you with a large, unexpected bill in April. Check with your HR or payroll department to see if you can adjust your RSU withholding rate to better match your actual bracket.
Thankfully, many companies offer a way to pay taxes at vesting — you can surrender enough stock back to the company to cover taxes, making it much easier to avoid a large income tax bill at filing time.
Since you’re receiving RSUs, you are likely already a high-income earner. Adding your vesting RSUs to the equation increases the possibility of pushing you into a higher income tax bracket. You’ll need to plan ahead. However, fluctuations are possible since the taxable income is based on the stock price. It’s also problematic because the number of shares vesting yearly may change. This means adjusting your tax withholding annually, and maxing out your or your spouse’s 401(k), HSA, or deferred comp plans to reduce or offset this additional taxable income.
📋 2026 401(k) Contribution Limits
| All employees | $24,500 |
| Age 50 or older (catch-up) | $32,500 |
| Age 60–63 (super catch-up) | $35,750 |
Since HSAs and deferred comp plans can generally be adjusted only during the open enrollment period, this becomes an annual balancing act.
Your RSUs Vested – Now What?
Now that your RSUs have vested, you own the stock. You must decide whether to hold your shares or sell them. The first step is determining the cost basis of your shares. The cost basis equals the market value of the shares the day they vest, which also happens to be the amount that is taxed as your compensation.
If you sell immediately, there is no additional tax beyond the compensation taxes already mentioned.
Example — Selling Immediately
You have 1,000 shares that vested at $30 per share = $30,000 of taxable compensation. You sell immediately on the vesting date.
$30,000 (sales proceeds) – $30,000 (cost basis) = $0 capital gain or loss.
No additional tax beyond what was already owed at vesting.
However, if you decide to hold your shares but sell them within a year of vesting, any gains are considered short-term and taxed at higher ordinary income tax rates.
Example — Short-Term Capital Gain (held under 1 year)
You have 1,000 shares that vested on 12/15/2024 at $30 per share = $30,000 of taxable compensation in 2024. You hold onto them, but sell on 4/2/2025 at $35 per share.
$35,000 (sales proceeds) – $30,000 (cost basis) = $5,000 short-term capital gain, taxed as ordinary income at your regular tax rate.
Maybe you have no plans to sell your shares. When you hold your shares for longer than a year before selling, the gains are subject to much lower long-term capital gains rates. Realized gains would be taxed at 15% or 20%, depending on your taxable income.
| Type of Gain | Rate | Single Filer Income | Married Filing Jointly |
|---|---|---|---|
| Long-term (held > 1 year) |
0% | Up to $49,450 | Up to $98,900 |
| Long-term (held > 1 year) |
15% | $49,451 – $545,500 | $98,901 – $613,700 |
| Long-term (held > 1 year) |
20% | Over $545,500 | Over $613,700 |
| Short-term (held ≤ 1 year) |
10–37% | Taxed as ordinary income — same as your regular tax bracket | |
| Net Investment Income Tax (NIIT) Additional surcharge for high earners |
+3.8% | MAGI over $200,000 | MAGI over $250,000 |
Example — Long-Term Capital Gain (held over 1 year)
You have 1,000 shares that vested on 12/15/2023 at $30 per share = $30,000 of taxable compensation in 2023. You hold onto them and sell on 2/12/2025 at $40 per share to buy a new car.
$40,000 (sales proceeds) – $30,000 (cost basis) = $10,000 long-term capital gain, taxed at 15% or 20% depending on your income — significantly lower than ordinary income rates.
The examples above show what happens when the stock price increases and results in capital gains. If the stock price decreases, you can deduct the capital losses. Losses are first applied to any gains, and then can be applied to other taxable income — with a limit of $3,000 per year. If any losses remain, they carry over to the following year or years as needed.
One item to be aware of: many companies restrict when employees can trade company stock. This helps protect both of you against insider trading. If you have trading windows, you need to factor those into the financial planning equation
Too many RSUs in one basket
Although RSUs are an excellent way to increase your wealth, there is a risk of holding too much company stock. Think of it like a three-legged stool — your salary, your benefits, and your investment portfolio. If all three legs are made from the same piece of wood (your employer), and that wood cracks, the whole stool falls. Even if your employer is doing well and the stock continues to climb, nobody can predict the stock market or the future fortunes of your employer. You need to protect yourself with a well-diversified portfolio.
Your job is usually a big enough “investment” in one company. Retirement investments should be diversified. Make sure your RSUs, if you’re holding on to them, fit into a diversified investment strategy. Be careful not to tie up too much of your net worth with your employer.
RSUs – living beyond your means
Don’t become reliant on RSUs to live beyond your means. You can’t predict the value of the RSUs at the time of vesting. Stock prices fluctuate, and sometimes not in a good way. Do not treat RSUs as a source of income to meet your living expenses. Use them as savings devices. Whether keeping them as stock or cashing them out and saving the proceeds elsewhere, it’s wise not to have RSUs pay the monthly expenses. Instead, use RSUs to increase savings, pay off debt, or both.
Planning For the Future
RSUs are an excellent employer benefit that can help you retire, improve cash flow, pay off debts, or achieve other financial goals. They can set you up for long-term financial success if used and planned for properly. Because the tax picture is complex and changes annually, it’s worth having a coordinated plan that considers your vesting schedule, tax bracket, 401(k) strategy, and overall investment mix.
