Updated July 28, 2026. Quick answer: Holding buys you nothing on the income already taxed at vest — that is done either way. What holding actually does is convert a decision about compensation into a decision to buy your employer’s stock with after-tax money.
Reframe the question
At vest you paid ordinary income tax on the full value. The shares now sit in your account with a basis equal to that value. Holding them is economically identical to taking the cash and buying the same shares on the open market.
So the honest question is not “should I sell?” It is: with this after-tax money, would I buy my employer’s stock today? Most people answer that differently than they answer the first version.
What holding does and does not change
| Effect | Selling at vest | Holding |
|---|---|---|
| Tax on the vest itself | Already paid | Already paid — identical |
| Future gain | None | Capital gain or loss from the vest-date basis |
| Long-term rates | N/A | Available after a year from vest |
| Concentration | Removed | Salary and portfolio tied to one company |
The concentration point is the real one
Your salary already depends on this company. Holding stacks investment risk on top of employment risk in the same name, which is the opposite of diversifying.
The one-year clock starts at vest
Long-term capital gain treatment requires more than a year from the vest date, not from the grant date. Holding for eleven months captures the concentration risk without the rate benefit, which is the worst combination.
If you do hold, decide in advance
The reason holding drifts into permanent concentration is that no decision is ever made again. Setting a rule before the vest — a share count, a price, a calendar date — converts a series of non-decisions into one decision you can actually evaluate later.
