RSU Tax Trap: How Tech Employees Should Manage Company Stock
Key Takeaways
• RSUs are taxed as ordinary income when they vest, even if the shares are not sold
• Holding shares after vesting exposes employees to additional investment risk
• Many tech professionals unknowingly accumulate large concentrations of company stock
• Diversification decisions often matter more than tax timing
• A thoughtful strategy can help turn equity compensation into long-term wealth
Why RSUs Can Be Both an Opportunity and a Risk
Restricted Stock Units have become one of the most significant wealth-building opportunities for professionals working in technology.
Many employees receive a substantial portion of their compensation in company stock. Over time these grants can grow into a meaningful part of net worth.
However RSUs also create some of the most common financial planning mistakes. When the first large vest occurs, employees suddenly face questions they may not have considered before.
Should the shares be sold or held?
How much tax will be owed?
How much company stock is too much?
Understanding how RSUs work can help avoid what is often called the RSU tax trap.
What Are RSUs?
Restricted Stock Units are shares of company stock granted to employees as part of compensation.
These shares vest over time according to a schedule set by the employer. Once shares vest, they belong to the employee and can either be held or sold.
At the time of vesting the value of the shares is treated as income for tax purposes. This means taxes are owed even if the employee decides to continue holding the shares.
For many technology professionals, RSUs eventually become one of the largest components of total compensation.
How RSUs Are Taxed
When RSUs vest, the value of the shares is taxed as ordinary income.
This income appears on the employee’s W-2 and is taxed similarly to salary or bonuses.
A few key things to understand:
• Taxes are owed even if the shares are not sold
• Some shares may be automatically withheld for taxes
• Federal withholding on RSUs is often around 22 percent
• Many high earners fall into higher tax brackets
Because withholding may not cover the full tax liability, employees are sometimes surprised by additional taxes owed when they file their return.
Thoughtful RSU tax planning becomes increasingly important as equity compensation grows.
Capital Gains After RSUs Vest
Once RSUs vest and income taxes are paid, the shares become an investment like any other stock.
If the stock price increases after vesting and the shares are later sold, the additional gain may be taxed as capital gains.
Short-term capital gains apply if shares are sold within one year.
Long-term capital gains apply if shares are held longer than one year.
Because long-term capital gains rates are often lower, many employees consider holding shares longer.
This is where the RSU tax trap often begins.
Understanding the RSU Tax Trap
The RSU tax trap occurs when employees hold shares after vesting in hopes of benefiting from long-term capital gains treatment.
The idea sounds logical. If the stock appreciates and the shares are held for more than one year, the gain may be taxed at a lower rate.
However the original value of the RSUs was already taxed as ordinary income at vesting.
Holding the shares does not change that tax. Instead it exposes the employee to additional investment risk.
If the stock declines after vesting, taxes were already paid on a higher value.
Over time this can also lead to a large concentration of company stock within a portfolio.
The Cash Test
A helpful way to evaluate RSUs is to ask a simple question.
If I received this amount as a cash bonus today, would I choose to buy my company’s stock?
If the answer is no, it may be worth considering whether some shares should be sold and diversified.
This does not mean every employee must sell all shares. Many professionals choose to keep a smaller intentional position while diversifying the rest.
Why Concentration Risk Matters
Holding a large amount of company stock introduces a unique risk.
Your salary, career, and investments may all depend on the same company.
If the company experiences difficulties, both your job and investment portfolio could be affected simultaneously.
Many investors reduce this risk by gradually selling portions of RSUs as they vest and reinvesting the proceeds into a diversified portfolio.
This approach allows company stock to contribute to wealth building without dominating a financial plan.
RSUs Within a Larger Financial Plan
Equity compensation decisions rarely exist in isolation.
RSUs often connect with other financial planning decisions such as:
• retirement planning
• tax strategy
• home purchases
• family financial planning
For professionals in their 30s and 40s, managing RSUs effectively is often part of turning career success into long-term financial security.
Final Thoughts
Restricted Stock Units can be a powerful wealth-building tool.
But opportunity alone does not guarantee long-term success.
The difference often comes down to how taxes, diversification, and investment decisions work together.
A thoughtful strategy can help turn equity compensation into lasting financial progress.
