Why selling at vest usually costs little in tax
When RSUs vest, their full market value is taxed as ordinary income, the same as a cash bonus. That income is taxed whether you sell the shares or not. Your cost basis in the shares becomes their value on the vest date.
So if you sell soon after vest, there is usually little or no additional tax: only the gain or loss between the vest date and the sale. The tax that matters has already been triggered. Our post on RSU tax withholding covers why the amount withheld at vest often falls short of that bill.
The long-term capital gains myth
A common reason for holding is to "get long-term capital gains." Holding for more than a year after vest does qualify any further growth for long-term rates. It does nothing for the value at vest, which is already taxed as ordinary income. The tax benefit of holding applies only to future appreciation, and you take on the full risk of the shares to get it.
The bonus test
Picture the vest as a cash bonus deposited into your account. Would you use all of it to buy your employer's stock today? If the answer is no, holding the RSUs is the same decision you just declined, made by default.
The test is useful because it removes two biases: the feeling that the shares are "free" and the habit of keeping things where they arrive.
Concentration and your paycheck
Your job and your company stock depend on the same business. If the company struggles, your shares can fall at the same time your bonus shrinks, your unvested grants lose value, or your role is at risk. That correlation is the core reason diversification matters more for employee shareholders than for outside investors.
Many planners set a ceiling on employer stock as a share of net worth, often expressed as a percentage, and treat anything above it as a candidate for sale. The right ceiling depends on your other assets, your income stability, and your goals.
Reasons people reasonably hold
- Ownership guidelines. Many companies require executives to hold a set value of stock. Selling below that level may not be allowed.
- Planned charitable gifts. Shares held more than a year after vest that have appreciated can be donated, often with a deduction for their market value and no capital gains tax on the appreciation.
- A deliberate, sized position. Some people choose to keep a defined amount of company stock as part of a diversified portfolio, with a written limit.
Each of these is a decision with a reason and a limit. Holding everything because selling feels disloyal or because the stock "has to come back" is not.
How to sell well
Choose your lots
If you hold shares from several vests, each lot has its own basis and holding period. Selling with specific identification lets you choose high-basis lots first to minimize gain, or harvest a loss. Set this up with your broker before the trade; a default method may choose for you.
Mind the trading windows
Insiders can usually trade only during open windows under the company's insider trading policy. Affiliates face Rule 144 conditions as well. A 10b5-1 plan can schedule sales at vest so they happen without a decision each quarter.
Decide where the proceeds go
Selling only helps if the money is put to work: an emergency reserve, a tax payment, a down payment, or a diversified portfolio. Decide before the vest.
Hypothetical example: Meet "Jordan," a director at a public company with RSUs vesting every quarter. Jordan sets a rule: sell each vest at the next open window, except for enough shares to meet the company's ownership guideline. The rule turns twelve decisions a year into one.
Common mistakes
- Holding to "get long-term capital gains" on income that is already taxed.
- Letting vests accumulate until company stock dominates your net worth.
- Selling without choosing tax lots.
- Forgetting that withholding at vest may not cover the full tax.
- Reporting the 1099-B cost basis without adjusting it. See what to give your CPA.
