How RSUs Are Taxed: At Vest and When You Sell

As of October 20, 2026.
The short answer
Restricted stock units (RSUs) are generally taxed as pay when the shares are delivered to you, usually at vesting.
The value on that day shows up as wages on your Form W-2, just like a cash bonus.
That same value becomes your cost basis in the shares.
When you sell, only the move in price since vest is a capital gain or loss.
What happens at vest
Nothing is taxed at grant. An RSU is a promise of shares later.
At vest, the value of the shares counts as wages. Income tax, Social Security and Medicare generally apply.
Most employers sell or hold back some shares to cover the withholding.
Your holding period for the shares starts at vest, not at grant.
Why 22% often isn't enough
Employers can withhold federal tax on bonuses and other extra pay at a flat 22%.
Once your extra pay from one employer passes $1 million in a year, the rate on the excess is 37%.
If your tax bracket is above 22%, the difference is due when you file.
Live in New York City? State and city tax apply too, so check those withholding lines as well.
Short for 2026? A new Form W-4 or an estimated payment can help. The last 2026 estimate is due January 15, 2027.
What happens when you sell
Held more than one year after vest: a long-term gain or loss, which may be taxed at a lower rate.
Held one year or less: short-term, taxed at ordinary income rates.
Sell soon after vest and the gain or loss is usually small, since your basis is close to the sale price.
Keeping the shares is a fresh investment decision. The tax on the vest is owed either way.
Three common mistakes
Paying tax twice. Check that the basis on your broker's Form 1099-B includes the amount already taxed on your W-2. If it doesn't, the IRS has you correct it on Form 8949.
Selling the wrong shares. If you can identify which lots you sell, you use their basis. If you can't, the IRS treats the oldest shares as sold first.
Tripping the wash sale rule. Sell at a loss and buy the same stock within 30 days before or after, and the loss can be disallowed for now. Ask your preparer whether a vest or an ESPP purchase near the sale counts.
Questions to ask before your next vest
When do my next shares vest, and about how much are they worth?
How much was withheld on this year's vests?
Is my tax bracket above 22%?
Which lots would I sell first, and how long have I held each one?
Does the basis on my 1099-B match what's on my W-2?
Review these with the person who prepares your return.
