Your RSUs just vested. A batch of shares appeared in your brokerage account, a chunk was withheld for taxes, and now you're staring at a balance wondering what to do.
If you're like most tech professionals, the answer is: nothing. You leave the shares sitting there, maybe check the stock price a few times a week, and wait for the next vesting date to repeat the cycle.
But doing nothing is itself a decision, and it may be one of the most consequential financial choices you make each quarter. The moment your RSUs vest, you're no longer receiving compensation. You're making an active investment decision about whether to hold a concentrated position in a single stock.
What Actually Happens When RSUs Vest
Restricted Stock Units are a promise from your employer: stay with the company through a vesting schedule, and you'll receive shares of stock. When those shares vest, the fair market value on that date is included in your ordinary income and reported on your W-2. The IRS generally treats the vested value of RSUs as compensation income, taxable in the year of vesting. Your employer withholds taxes on your behalf, typically by selling a portion of the shares before they hit your account.
This is the critical point most people miss: the biggest tax event happens at vesting, whether you sell the shares or keep them.
You don't trigger a new round of ordinary income tax by selling immediately afterward. If you sell right after vesting, there is usually little or no additional capital gain or loss because the sale price is likely close to the value already included as ordinary income. Your cost basis in the shares is the fair market value on the vesting date, so an immediate sale at that same price produces minimal taxable gain.
Think of it like a direct deposit. Your employer paid you in stock instead of cash, and the IRS taxed it as income the moment it landed. From that point forward, any gain or loss is an investment outcome, not a compensation event.
The Big Question: Would You Buy This Stock Today?
Here is the mental model that should anchor every RSU decision you make going forward:
If your vested RSUs were cash in your account today, would you use that cash to buy your employer's stock?
If the answer is no, holding the shares is doing exactly that. You're choosing, every day you don't sell, to keep your money invested in a single company. Holding can be reasonable, but it should be intentional. "I don't want to miss upside" is not the same as having an investment thesis.
Loyalty to the company is not a diversification strategy. A great employer can still be a risky single-stock holding.
This reframing helps cut through the emotional fog that surrounds RSU decisions. Many people treat vested shares as a gift they shouldn't touch, or as proof that their company is a winner. But once the shares vest, you own stock, the same stock anyone else could buy on the open market.
Your relationship with the company doesn't change the risk profile of the investment. The only question is whether that stock, at today's price, deserves the allocation it currently occupies in your portfolio.
The Concentration Problem for Tech Professionals
For technology professionals receiving RSUs, the risk goes far beyond owning a single stock. Your financial life may be tied to the same company in multiple overlapping ways:
Your salary comes from the company.
Your annual bonus may depend on company performance.
Future RSU grants depend on the company's stock price and your continued employment.
Your career capital and professional network may be concentrated in the same industry.
Your index funds and growth ETFs likely already hold meaningful positions in the same stock or sector.
If your employer hits a rough patch, your job security and your portfolio may be under pressure at the same time. This is the definition of correlated risk.
A broad market downturn might reduce your 401(k) balance, but a company-specific crisis could simultaneously threaten your income, your unvested equity, and the value of the shares you've been accumulating.
Consider the analogy of a farmer who grows only one crop. In a good year, the harvest is spectacular. But a single drought, pest outbreak, or price collapse can wipe out everything. Diversification across crops protects the farm. Diversification across investments protects your wealth.
Concentration risk compounds when your paycheck, your bonus, your future equity, and your investment portfolio all depend on the same company or sector. Diversifying your vested RSUs is one of the most direct ways to reduce that overlap.
The Stock Doesn't Know You Work There
Employees often feel they have an informational edge because they see the product roadmap, understand the company culture, and know which projects are gaining traction internally. That confidence is understandable, but it doesn't always translate into better investment outcomes.
Public stock prices already reflect an enormous amount of known information: analyst estimates, competitive dynamics, macroeconomic trends, and forward guidance from the company itself.
What you observe internally, such as strong team morale or an exciting product launch, may already be priced into the stock. And insider trading regulations mean you can't legally act on material nonpublic information anyway.
Working at the company may give you context, but it can also make the stock harder to evaluate objectively. Psychologists call this the endowment effect: people tend to overvalue things they already own.
When you combine the endowment effect with pride in your employer and the social reinforcement of colleagues who are also holding, it becomes very easy to let concentration build unchecked.
When Holding RSUs Can Make Sense
This article is not an argument to sell every share the moment it vests. There are scenarios where holding some or all of your vested RSUs is a deliberate, well-reasoned choice:
Company stock represents a modest portion of your total investable assets, perhaps under 10%.
You have strong cash reserves and no near-term liquidity needs.
Your other financial goals, such as emergency fund, retirement contributions, and debt payoff, are already funded.
You understand and accept the concentration risk after reviewing your full balance sheet.
You have a written sell discipline: a specific trigger, percentage threshold, or time-based rule for when you will reduce the position.
You're holding a limited percentage as part of a broader, diversified portfolio.
You have trading-window restrictions or other company-specific constraints that require a more structured approach.
The goal is to avoid letting inertia become your investment strategy. If you've reviewed your total exposure, stress-tested the downside, and still want to hold a defined percentage of your net worth in employer stock, that's a valid decision. The problem arises when shares simply pile up because no one ever made a plan.
When Selling at Vest Often Makes Sense
Selling some or all of your vested RSUs deserves serious consideration in several common situations:
Company stock exceeds 10% to 15% of your investable assets. Many financial professionals use this range as a starting point for evaluating single-stock concentration. This is a guideline, not a hard rule, but it provides a useful benchmark.
You have additional RSUs scheduled to vest. Even if today's balance seems manageable, future vesting events will keep adding to the position unless you actively trim.
You need cash for taxes. Withholding at vesting may not cover your full tax liability, especially if you're in a high marginal bracket (more on this below).
You're saving for a specific goal. A home down payment, an emergency fund, or a major purchase is often better funded with liquid, diversified assets than with a volatile single stock.
You're already heavily exposed to tech. If your career income depends on the technology sector and your index funds hold large positions in the same companies, adding more employer stock amplifies an existing concentration.
You don't have a clear reason to own more employer stock. The absence of a sell thesis is not the same as having a buy thesis.
Your net worth depends too heavily on one company. If a 30% to 50% decline in the stock would meaningfully alter your financial trajectory, the position may be larger than your risk tolerance warrants.
Selling at vest is often a disciplined default, but the right answer depends on your concentration, taxes, goals, and the broader portfolio. The point is to make the decision consciously rather than passively.
Don't Forget the Tax Reserve
One of the most common surprises for high-earning RSU recipients comes at tax time. Employers commonly withhold taxes on supplemental wages at a flat federal rate (currently 22% on supplemental wages up to $1 million, and 37% above that threshold). But your actual marginal tax rate may be significantly higher when you factor in your total income, state taxes, bonus compensation, and other equity events throughout the year.
The shares withheld at vesting may cover part of the tax bill, but high earners should not assume that withholding equals the final tax owed. If you live in a state with high income tax rates, such as California or New York, and you're in the top federal brackets, the gap between what was withheld and what you actually owe can be substantial.
Selling a portion of vested shares specifically to build a tax reserve can prevent an unpleasant surprise in April. This is an area where working with a CPA or tax advisor is especially valuable, as they can help you estimate quarterly tax obligations and avoid underpayment penalties.
Create a Rule Before the Next Vesting Date
The best RSU decisions are made before the shares hit your account. When you create a standing decision rule in advance, you remove the emotional component from a choice that repeats every quarter. Here are several frameworks that Pantile clients commonly adopt:
Sell 100% at vest and diversify. The simplest approach. Every vesting event triggers an automatic sale, and proceeds are reinvested according to your broader plan.
Maintain a concentration ceiling. Sell enough to keep employer stock below 10% to 15% of investable assets. This automatically adjusts for stock price changes and portfolio growth.
Sell 50% immediately, review the rest quarterly. A middle ground that captures some diversification benefit while giving you time to evaluate the remaining position.
Hold a fixed dollar amount. Decide you're comfortable with, say, $50,000 in employer stock, and sell anything above that threshold.
Goal-based selling. Direct RSU proceeds toward specific objectives: fund your emergency reserve first, then your backdoor Roth IRA, then your taxable brokerage account.
Calendar-based selling. Sell on a fixed schedule (monthly, quarterly) regardless of price, similar to dollar-cost averaging in reverse.
A rule-based RSU strategy helps remove emotion from a decision that repeats every quarter. Write your rule down, share it with your financial advisor or accountability partner, and revisit it annually to make sure it still fits your circumstances.
What to Do With the Proceeds
Selling RSUs is only half the decision. The real value comes from turning concentrated company stock into a broader wealth-building plan. Without a reinvestment strategy, proceeds can sit in cash for months, earning minimal returns and quietly losing purchasing power to inflation.
Consider directing your RSU proceeds toward these priorities, roughly in order:
Set aside your estimated tax obligation. Before anything else, make sure you have enough to cover the gap between what was withheld and what you'll actually owe.
Build or replenish your emergency fund. Three to six months of expenses in a liquid account provides a foundation for every other financial decision.
Pay down high-interest debt. Credit cards and personal loans with rates above 7% to 8% often represent a guaranteed return on capital when eliminated.
Maximize tax-advantaged accounts. Fund your 401(k) up to the annual limit, contribute to a backdoor Roth IRA if eligible, and max out your HSA if you have a high-deductible health plan.
Fund near-term goals. A home down payment, a 529 plan for your children's education, or another savings target with a defined timeline.
Invest in a diversified taxable portfolio. Once tax-advantaged space is full, a well-constructed brokerage account with broad market exposure can compound efficiently over decades.
Consider charitable giving. Donating appreciated shares held for more than one year can provide a tax deduction while avoiding capital gains, though this strategy requires careful planning with a tax advisor.
Each of these uses reduces your financial dependence on a single company and moves you toward a portfolio that can weather a variety of economic environments.
RSU Sell-or-Hold Checklist
Before your next vesting date, work through these questions. They won't give you a single "right" answer, but they will clarify whether your current approach is intentional or accidental:
What percentage of my investable assets is in employer stock?
How much more employer stock will vest over the next 12 to 24 months?
Would I buy this stock today if the shares were cash?
Do I need cash for taxes or near-term goals?
Am I already exposed to tech through my career and other investments?
What would happen to my financial plan if the stock fell 30% to 50%?
Do I have a written rule for future vesting dates?
How will I reinvest the proceeds if I sell?
If you answered "I'm not sure" to more than a couple of these, you have an opportunity to build a more deliberate strategy before your next batch of shares lands in your account.
RSUs are one of the most valuable components of modern tech compensation. They represent real wealth, earned through your talent and commitment. But that value only becomes lasting wealth when it's managed with the same rigor you bring to your work.
Turning a growing pile of company stock into a diversified, goal-aligned portfolio is one of the highest-impact financial moves a tech professional can make. If you have RSUs vesting soon or shares that have been accumulating without a plan, Pantile can help you evaluate your concentration risk, tax exposure, and reinvestment strategy so your equity compensation supports your long-term wealth plan.
