Cashed Out Stock Options or RSUs: What Do You Actually Do With That Money?

RSUs (Restricted Stock Units). When tax is due: At vesting, the full market value of vested shares is taxable as ordinary income the moment they vest, whether you sell the shares or not. Rate: Ordinary income rate (up to 37% federal + state). Treated exactly like salary. What to watch: Default 'sell-to-cover' withholding is often only 22% (the flat supplemental rate). For employees in the 35-37% bracket, this creates an underpayment gap that will be due at April 15.

NQSOs (Non-Qualified Stock Options). When tax is due: At exercise, the spread between the exercise price and the fair market value at exercise is taxable as ordinary income. Rate: Ordinary income rate on the spread. If you sell the shares later for a gain, that gain is taxed at capital gains rates. What to watch: Exercising a large block in a single year can push you into the highest marginal bracket unexpectedly. Timing of exercise relative to your other income is critical.

ISOs (Incentive Stock Options). When tax is due: At exercise, ISOs may trigger Alternative Minimum Tax (AMT). At sale, gains may qualify for long-term capital gains rates if holding requirements are met. Rate: Potentially long-term capital gains (0-20%) if holding period is satisfied. AMT can create a cash tax bill at exercise even without selling. What to watch: ISO exercises in large quantities can trigger significant AMT. Model this with a CPA before exercising a large ISO grant.

Shares held after vest (RSUs). When tax is due: No additional tax at vest beyond what was already paid. Future gain/loss from price movement after vest is taxed as capital gains. Rate: Long-term capital gains (0-20%) if held more than one year post-vest. Short-term rates (ordinary income) if held less than one year. What to watch: The decision to hold or sell vested RSU shares is a portfolio concentration decision, not a tax optimization decision. Ask: would I buy this much of this stock today with cash?

For RSU recipients specifically, the most common and most expensive mistake is assuming that the sell-to-cover withholding at vest covers your full tax liability. It almost never does.

Here is why: the IRS allows employers to withhold at a flat 22% supplemental rate on equity compensation. But if your total income for the year (salary plus the RSU vest value) puts you in the 32%, 35%, or 37% federal tax bracket, you have a gap of 10-15 percentage points that is owed at filing time. On a $200,000 vest, that gap is $20,000-$30,000 owed in April that most people are not holding in reserve.

The fix is straightforward but requires action before the vest event: work with a CPA to model your projected total income for the year, calculate the gap between the 22% withheld and your actual marginal rate, and either adjust your W-4 supplemental withholding or set aside the difference in cash in a dedicated tax reserve account.

Once you have confirmed your tax reserve is fully funded, the remaining proceeds are yours to deploy. Here is the decision framework:

The Concentration Risk Question: Before You Do Anything Else

Resilient Planning offers the clearest framing of this decision:

If your company had given you this bonus in cash, would you use all of it to buy company stock today? If the answer is no, then selling all is often the most logical choice.

Holding large blocks of vested RSU shares means your salary and your investment portfolio are exposed to the same company's performance simultaneously. If that company hits a rough patch, your income security and your net worth decline at the same time. This is the definition of concentrated risk, and it is usually not a risk worth taking for its own sake.

For most equity recipients, the most rational strategy is to sell vested shares and diversify the proceeds, unless you have specific, informed conviction about the company's trajectory that exceeds what the market has already priced in.

1. Tax reserve: Immediately set aside the difference between what was withheld and your estimated total tax liability for the year. This amount lives in a separate savings account until April 15.

2. High-interest debt elimination: Any credit card or personal loan debt above 8-10% interest. The guaranteed return on debt payoff exceeds what most investments will produce on a risk-adjusted basis.

3. Emergency fund: Three to six months of living expenses in a high-yield savings account. For variable-income earners or those considering career transitions, target six to twelve months.

4. Max-funded retirement accounts: Use the proceeds to free up income for Roth IRA, 401(k), or HSA contributions you might otherwise not be able to afford. The tax advantages on retirement accounts are often greater than any investment return.

5. Diversified long-term investments: Broad market index funds across domestic and international equities. Systematic monthly contributions reduce timing risk better than lump-sum deployment.

6. Entrepreneurial capital (optional, intentional): If you have been planning to start something, this is where the proceeds create an option. Keep this allocation to 10-20% of the total and only after the preceding items are addressed.

Equity compensation events are one of the clearest moments in a professional's financial life where a meaningful gap suddenly exists between where you are and where you could be. Most people either spend through it (lifestyle inflation that feels modest but compounds into six figures of lost investment capital) or they park it in savings and never deploy it with intention.

A third path exists: treat this as seed capital for something you build. A $100,000 to $200,000 equity payout, properly structured after taxes and foundation-building, is legitimate startup runway for a service-based business, a consulting practice, or an early-stage investment in a company where you have real knowledge and conviction.

If that path is on your mind, UnleashYourIdeas.com is the structured starting point, designed for people who have capital, skills, and intent, and need a disciplined framework for moving from idea to viable enterprise without burning through what they have built.
