For typical RSUs delivered at vesting, selling soon afterward can reduce company risk without adding much capital-gains tax. The compensation tax generally arises when the shares are delivered, whether you sell or keep them. Holding is therefore a fresh investment decision: how much more of your money do you want tied to the company that also pays your salary?
Start with the shares you actually own
Check the award type and when you can sell. RSUs, restricted stock, and options have different tax rules. A vesting date also does not guarantee liquidity: private-company shares, delayed delivery, and trading restrictions can change the timeline.
For a typical RSU delivery, the share value included in compensation generally becomes your tax basis. Later price changes create a separate capital gain or loss.
For example, suppose 100 shares are delivered at $50 each. That is $5,000 of compensation before withholding. If you sell all 100 at $52, the additional capital gain is $200, not $5,200. Keeping them for a year does not undo the original $5,000 of compensation income.
The IRS restricted-property guidance and stock-option rules explain why identifying the award matters. For RSUs, also check withholding and basis reporting before treating the broker’s proceeds as your taxable gain.
How much company risk can your household absorb?
Count more than the shares in your brokerage account. Your salary, bonus, unvested awards, and a partner’s job in the same industry can all depend on similar business conditions.
If $400,000 of a $1 million investment portfolio is employer stock, a 50% decline in that stock costs $200,000, or 20% of the starting portfolio, even if every other investment stays flat. A job loss at the same time would put further pressure on the household.
One useful question: If this award arrived as cash, would you use all of it to buy your employer’s stock today? A “no” does not mean you must sell every share. It means retaining the whole award needs a better reason than familiarity.
There is no employer-stock percentage that suits every household. Choose a limit using the loss you can absorb, the money you will need soon, and how much company exposure you already have.
Fund obligations before deciding what to keep
Set aside enough for taxes, emergency reserves, and planned spending before choosing the shares you want to hold for upside.
| If the shares are meant to fund… | The question to answer |
|---|---|
| A tax payment | How much is still due after withholding and estimated payments? |
| A home purchase next year | How much cash must be available even if the stock falls? |
| Long-term investing | How much single-company risk fits alongside the rest of the portfolio? |
Withholding is a payment toward tax, not proof the final bill is covered. And if a planned sale falls inside a blackout period, the money may not be available when you need it. Follow company restrictions and never trade on material nonpublic information.
Compare the destination as well as the sale
Selling employer stock reduces that particular company’s weight. What you buy next determines how much you diversify.
A broad portfolio may spread exposure across companies and industries. A technology fund might still hold your employer and many businesses affected by the same risks. Check the holdings alongside your retirement accounts instead of assuming that a different account name means different exposure.
Money for a near-term purchase has a different job from retirement savings. Decide its purpose before choosing the replacement investment.
Use a repeatable rule
Write down how much employer stock you intend to keep, how much cash each available sale window needs to raise, and when you will revisit the decision. Apply the same rule to the next award so every vest does not become a new debate about the share price.
You can sell part and keep part. You can also distinguish newly delivered RSUs with little capital gain from older shares with a large embedded gain. The tax cost of selling those two groups may differ substantially.
Keep the vesting schedule, household cash needs, tax estimate, and trading windows together. The RSU tax calculator can help estimate one piece; the sell-or-hold decision needs all four.
