Twelve hundred shares vested this morning. At today's close, that's more money than you cleared in salary last quarter. It's also the third grant to land this year, and between them, a single company's stock is back to being the largest position you own. You didn't exactly decide on that. It rebuilt itself one scheduled vest at a time, each one handled correctly, none of them arriving as a choice.
The standard advice is right
The playbook for a vest is well established, and there's nothing wrong with it. A portion of the shares is sold automatically to cover the tax withholding, the sell-to-cover line you'll see on the confirmation. From there, most guidance says to trim what's left rather than let it ride, since a stock you were handed as pay is still one company's stock, and to confirm that the amount withheld will actually cover what you owe. Sound advice, all of it. Apply it and you've handled this vest well.
Why it didn't feel like a decision
When a bonus hits, you notice it. A vest is easy to miss. You set the schedule once, when you signed an offer or accepted a grant, and after that it runs without you. The shares simply appear, and because it looks like the plan working as intended, the vest gets processed rather than decided. You handle the tax, maybe sell some, and move on to the parts of the day that actually asked for your attention.
Then it happens again
The grant that vested today isn't the last one. There's another date on the calendar, and another after that, each delivering more of the same company's stock into the same account. Trim the position now, and the next vest starts rebuilding it. The single-vest advice stays correct every time you apply it. What it never accounts for is the running total.
People will spend an hour on the tax treatment of a single vest, read up on cost basis and holding periods, and never once ask what share of their net worth now sits in one company. That's the part I'd push on.
You built this one piece at a time, with no map handed down. There was a 401(k) to sort out when the salary started, then withholding to get right after the first bonus, then RSUs to learn once the equity arrived. Each got handled as it came. What rarely gets asked, once there are enough pieces, is whether they still fit together.
What one vest at a time can't catch
Taken one at a time, every vest is fine. Stacked, they start touching things a single vest never raises. A grant that lands in the same year as a large bonus can push your income past a threshold, changing what you owe or phasing you out of something you'd been counting on. Withholding that looked adequate on each confirmation can fall short in aggregate, because when the flat supplemental-wage rate is used, it can sit below the marginal rate a high earner ultimately owes. And the concentration builds, quietly and on schedule, until one company's results carry more of your balance sheet than you would ever have chosen deliberately.
None of that is a flaw in the advice you were given. It was a right answer to the question in front of you. The trouble is the question nobody thought to ask: how much of your money is riding on a single company by the time all the vests are counted.
The concentration piece is worth pausing on, because it's the one most people underweight. Equity compensation behaves less like an investment you picked and more like a paycheck that happens to arrive as stock, and that difference changes how much of it you should be comfortable holding. I wrote about that here: Why Equity Compensation Is a Concentration Decision, Not Just an Investment Choice.
After the notification
Being told a vest happened is easy, and it keeps getting easier. Your equity platform emails you. Your calendar can remind you. What none of that does is look at whether this vest actually changes anything, given the bonus, the withholding, and what's already in the account, and then decide what to do before the next date arrives. A reminder can't do that. It takes someone whose job is to connect the vest to everything else in the picture, and on a vest that felt like paperwork, that's usually no one's job.
The question that stays open
None of this asks you to handle a vest differently. You already do that part well. It asks a different question, one level up: who is watching what the grants add up to, and when does that total need a second look. The next vest is already on the calendar. Whether someone is holding that larger question by the time it arrives is the part still in your hands.
If you're building wealth without an inherited playbook, a clear structure makes the next decision easier. It starts with a conversation.
Common questions
How are RSUs taxed when they vest?
At vesting, the market value of the shares counts as ordinary income for that year, and your employer withholds tax on it. If you later sell the shares for more or less than their value at vesting, that difference is a separate capital gain or loss.
What is sell-to-cover?
Sell-to-cover means a portion of the newly vested shares is sold automatically to cover the tax withholding, and you keep the rest. It's the most common default, though not the only method.
Do I have to sell my RSUs when they vest?
No. Once the shares vest and the withholding is handled, the rest are yours to hold or sell. Holding is still a choice, not a neutral default, since it keeps that money concentrated in a single company.
Why might the withholding on my RSUs fall short?
When an employer uses the flat supplemental-wage rate, the amount withheld can be lower than what a higher-income employee ultimately owes, leaving a gap that surfaces at tax time rather than on the vest date.
How much company stock is too much?
There's no universal figure. The more useful questions are what share of your total net worth sits in a single company, and whether a sharp decline in that one stock would put specific goals at risk. The answer depends on the rest of the picture, not on the stock alone.
