The Moment
RSUs create a strange combination of excitement and administrative complexity.
Because the value arrives through equity, many people instinctively treat it as an investment decision first. In reality, it is simultaneously compensation, a tax event, and a concentration decision. That is why drift is dangerous here. The default path often becomes keep holding without a clear reason.
The Short Answer
Treat RSUs as a three-part decision: 1. what the vesting means for taxes and withholding 2. how much concentration risk you are carrying 3. whether holding the shares is a real investment choice or just inertia

The classic April-15 surprise: companies withhold federal at the 22% supplemental rate, but your actual marginal rate may be much higher. This calculator shows the gap.

Why This Matters
RSU decisions influence taxable income, concentration in employer equity, cash available for taxes or diversification, and whether compensation and investment risk become too correlated.
The goal is not to maximize excitement. It is to make the equity fit your broader financial structure.
Decision Logic
If the employer stock already dominates your net worth, concentration matters more. If withholding will be insufficient, cash planning becomes urgent. If you would not buy this stock fresh with cash, examine why you are holding it. If multiple vesting dates are approaching, the timing plan matters more. If RSUs are tied closely to your household goals, treat them as compensation capital, not abstract portfolio assets.
Common Mistakes
Treating vested shares as if they are automatically long-term investments. Ignoring concentration risk because the company feels familiar. Forgetting withholding implications. Holding by default instead of choice.
What Changes the Answer
Size of RSU grants, employer concentration in your net worth, withholding level, household liquidity, and future vesting schedule.

Frequently Asked Questions

What is the biggest RSU tax mistake?
Ignoring the interaction between tax withholding, concentration risk, and the emotional tendency to keep holding by default.
