Wealth management for tech employees with RSUs and stock options

Tech employees often receive RSUs (Restricted Stock Units) and stock options as part of their compensation, which can be a significant financial opportunity. However, managing these assets can be complex, with tax implications, vesting schedules, and risks tied to company stock. Here's what you need to know:

• RSUs: Taxed as ordinary income at vesting. Companies withhold 22% for taxes, but higher-income earners may owe more.
• Stock Options: Require action to exercise. ISOs may offer tax advantages but could trigger AMT. NSOs are taxed as income at exercise.
• Tax Strategies: Consider adjusting withholding, spreading stock option exercises, and using tax-advantaged accounts like 401(k)s or HSAs to offset equity income.
• Diversification: Limit employer stock to 10%-15% of your portfolio to reduce risk. Staged selling or automated plans (e.g., 10b5-1) can help.
• Long-Term Goals: Align vesting events with financial goals, like home purchases or retirement, and consider donating appreciated shares for tax benefits.

Managing equity compensation requires planning to minimize taxes, mitigate risks, and align with your financial objectives. Tools like Mezzi can assist by analyzing your accounts, flagging tax risks, and helping with diversification strategies.

Equity Compensation 101: What to Do With RSUs & Stock Options

RSUs and Stock Options Explained

Before diving into any strategy, it’s essential to understand how your equity compensation works. RSUs (Restricted Stock Units) and stock options are both common forms of equity compensation, but they operate in distinct ways. Confusing the two could lead to unintended tax consequences or missed opportunities.

How RSUs Work

RSUs represent a promise from your employer to provide shares of company stock after you meet specific conditions, usually tied to RSU vesting schedules. A typical RSU vesting schedule spans four years with a one-year cliff. This means you don’t receive any shares until your first anniversary, after which shares are released incrementally - often monthly or quarterly - until fully vested.

The tax treatment for RSUs is relatively straightforward but requires careful attention. When your RSUs vest, the fair market value (FMV) of the shares is treated as ordinary income and included on your W-2, much like your salary. To cover taxes, most companies employ a sell-to-cover approach, automatically selling a portion of your shares to meet withholding requirements. The IRS sets a default withholding rate of 22% for supplemental wages under $1 million. However, as one financial educator at InverseWealth points out:

"22 percent is what gets withheld. It is not what you owe." - InverseWealth

If you fall into a higher tax bracket, you may owe additional taxes when filing. Once your shares vest, the FMV on that date becomes your cost basis. Any future gains or losses when you sell the shares are treated as capital gains or losses.

How Stock Options Work: ISOs vs. NSOs

Stock options give you the right to purchase company shares at a fixed price, known as the strike price, which is set when the options are granted. Unlike RSUs, stock options require you to take action by exercising your right to buy the shares. If the stock price stays below the strike price, the options may expire worthless.

There are two main types of stock options:

• Incentive Stock Options (ISOs): These are available only to employees and offer potential tax advantages. If you hold the shares for at least one year after exercising and two years after the grant date, any gain is taxed at the long-term capital gains rate instead of as ordinary income. For instance, on a $500,000 gain, this favorable tax treatment could save $85,000 to $110,000 in federal taxes. However, exercising ISOs can trigger an AMT (Alternative Minimum Tax) adjustment based on the bargain element - the difference between the stock’s FMV and the strike price - even if you don’t sell the shares. It’s important to model your AMT exposure carefully.
• Non-Qualified Stock Options (NSOs): NSOs can be granted to employees, consultants, and board members. When you exercise NSOs, the difference between the market price and the strike price is taxed as ordinary income right away. Employers typically withhold taxes at the 22% supplemental rate. Unlike ISOs, NSOs aren’t subject to AMT, nor do they offer long-term capital gains treatment on the initial spread.

"The engineer who exercises a large ISO lot in November and waits for the tax preparer to compute AMT in March is the canonical surprise-tax case." - Sumeet Ganju, Founder & Investment Adviser, InverseWealth LLC

For 2026, the AMT exemption is $90,100 for single filers and $140,200 for married couples filing jointly, with phaseouts starting at $500,000 and $1,000,000, respectively. Understanding these thresholds and planning ahead can help you avoid unexpected tax surprises when exercising ISOs.

RSUs vs. Stock Options: Key Differences

Feature	RSUs	ISOs	NSOs
Tax Trigger	Vesting	Sale (if holding requirements are met)	Exercise
Tax Type	Ordinary income	Long-term capital gains (if qualifying)	Ordinary income on the spread
Cost to You	$0	Strike price	Strike price
AMT Impact	None	Bargain element is an AMT adjustment	None
Risk Level	Lower risk - shares retain value unless stock drops to $0	Riskier, as shares may expire worthless	Riskier, as shares may expire worthless
Post-Termination Window	N/A	Approximately 90 days to retain ISO status	Defined by the option agreement

RSUs are generally simpler and carry less risk since they have intrinsic value once vested. Stock options, on the other hand, offer the potential for higher returns but come with added complexity and risk, especially if the stock price doesn’t rise as expected. Up next, we’ll look at tax strategies to help you make the most of your equity compensation.

Tax Strategies for RSUs and Stock Options

Building on the earlier breakdown of RSUs and stock options, this section focuses on tax strategies that may help reduce liabilities during key equity events. Each stage - vesting, exercising, and selling - triggers unique tax obligations, offering opportunities to manage what you might owe.

How to Handle RSU Taxes at Vesting

When RSUs vest, the IRS treats their full fair market value (FMV) as ordinary income. While your employer automatically withholds taxes, the default federal rate for supplemental wages is 22%. If your marginal tax rate is higher - such as 32%, 35%, or 37% - you may owe an additional 10 to 15 percentage points at tax time.

Marginal Tax Bracket	Withholding Rate	Federal Tax Gap
24%	22%	2%
32%	22%	10%
35%	22%	13%
37%	22%	15%

To address this, update Form W-4, Step 4(c), to include extra flat-dollar withholding. For larger gaps, consider making quarterly estimated payments using Form 1040-ES to avoid penalties.

When you sell vested shares, confirm the cost basis listed on your Form 1099-B. The correct cost basis is the FMV on the vesting date, which has already been taxed as income on your W-2. Using an incorrect basis could result in paying taxes on the same income twice.

"Filing Schedule D using the unadjusted 1099-B basis means you pay tax twice on the same income, once at vest and again at sale." - InverseWealth

To avoid this, cross-check your brokerage's supplemental statement for accuracy before filing.

Building a Stock Option Exercise Plan

Stock options, unlike RSUs, let you decide when the tax event occurs, making planning critical. A common approach is to spread exercises across multiple years to manage income levels and avoid higher tax brackets or triggering the Alternative Minimum Tax (AMT).

For NSOs, the difference between the strike price and market price is taxed as ordinary income at exercise. By staggering exercises - such as splitting them between the last quarter of one year and the first quarter of the next - you may keep income spikes more manageable. Lower-income periods, like gaps between jobs or parental leave, can also be good opportunities to exercise options at a reduced rate.

ISOs, on the other hand, require careful modeling. While exercising ISOs doesn’t typically trigger ordinary income tax if holding requirements are met, the "bargain element" (FMV minus strike price) counts as an AMT preference item. Exercising too many ISOs in a single year could push you into AMT territory, potentially creating a tax bill even if you haven’t sold the shares. To avoid this, evaluate your potential AMT exposure before exercising.

When planning exercises, prioritize by expiration dates and the "moneyness" of the options to avoid unnecessary losses from lapses.

Using Tax-Advantaged Accounts to Offset Equity Income

Although no strategy completely eliminates taxes on equity income, using tax-advantaged accounts can help reduce taxable income in years with significant equity events. The 2026 contribution limits provide several ways to do this:

• 401(k): Contribute up to $24,500 annually ($32,500 if age 50 or older). If your plan allows after-tax contributions with in-service Roth conversions, a mega backdoor Roth could let you shelter up to $72,000 annually, offering a way to grow equity proceeds tax-free.
• HSA: Contribute $4,400 for individual coverage or $8,750 for family coverage. Contributions are deductible, and funds grow tax-free when used for qualified medical expenses.
• IRA: Contribute up to $7,500 annually ($8,600 if 50+), depending on income limits for deductibility or Roth eligibility.

Beyond contributions, asset location can play a role. Holding bonds or dividend-paying funds in tax-deferred accounts while keeping growth-oriented equity in taxable accounts may reduce the tax impact over time. Tools like Mezzi’s AI can analyze your accounts - 401(k), Roth IRA, brokerage - and suggest optimal asset placement to minimize overall tax drag, all without requiring you to move platforms.

Diversifying Out of Employer Stock

Reducing concentration risk is a key step in protecting your financial stability. While tax strategies may help manage liabilities, they don't address the risks tied to having too much of your wealth in a single company's stock. With each vesting event, the potential for this risk grows.

How to Measure and Reduce Concentration Risk

To gauge your exposure, divide the value of your employer stock by your total net worth. If the result exceeds 15%, it may signal a need for diversification. A figure above 40% could leave you vulnerable to major financial setbacks.

Consider this: if 60% of your net worth is tied to one stock and that stock drops by 40%, your overall net worth could decrease by 24% - all from that single position. The table below illustrates how losses can compound based on different levels of stock concentration:

Stock Decline	20% Concentration	40% Concentration	60% Concentration
Minus 20%	-4% to portfolio	-8% to portfolio	-12% to portfolio
Minus 40%	-8% to portfolio	-16% to portfolio	-24% to portfolio
Minus 60%	-12% to portfolio	-24% to portfolio	-36% to portfolio

(Source: Fortrove Partners [5])

For tech employees, this risk is often amplified since your income and career may already depend on the same company. A downturn could lead to both a layoff and a sharp decline in your portfolio at the same time.

"The same concentration that built your wealth can destroy it." - Joe Forish, CFA, CFP®, Fortrove Partners

One effective way to reduce exposure is staged selling - selling a fixed amount of stock on a set schedule, such as quarterly. This approach spreads tax liabilities over time and removes emotional decision-making. Aim to limit employer stock to 10%-15% of your total portfolio. For corporate insiders or those subject to trading restrictions, a 10b5-1 trading plan can automate this process while ensuring compliance.

Before each vesting event, ask yourself: "If this were cash, would I reinvest it in company stock?" If the answer is no, it may be time to sell.

Building a Diversified Portfolio

Once you've reduced your employer stock, the next step is creating a portfolio that doesn't rely on your company's performance. A good starting point includes:

• Broad U.S. equity ETFs, like a total market fund
• International equity ETFs for geographic variety
• Bonds or Treasuries to balance out volatility

Research suggests that holding at least 25 companies across different sectors and regions can significantly reduce individual stock risk. A single broad index fund can often achieve this diversification.

Your portfolio's mix should reflect your age and risk tolerance. Younger employees with more time before major financial goals may lean toward higher equity exposure. Those nearing milestones like home purchases, early retirement, or education funding might benefit from a greater allocation to fixed-income investments to reduce volatility.

Another useful tactic is harvesting capital losses. If you have underperforming assets - such as crypto or individual stocks - selling them at a loss can help offset the gains from selling employer stock in the same tax year.

To fine-tune your diversification strategy, consider using tools like Mezzi's Portfolio X-Ray.

How Mezzi's Portfolio X-Ray Supports Diversification

Even after selling employer stock and purchasing "diversified" funds, hidden risks can remain. For example, a tech employee holding VOO (S&P 500) and QQQ (Nasdaq 100) alongside their employer stock might not realize that Apple accounts for 7.1% of VOO and 11.2% of QQQ. This means their "diversified" funds might still heavily lean on the same tech giants.

Mezzi's Portfolio X-Ray tool uncovers these overlaps by analyzing all connected accounts - Fidelity, Vanguard, Schwab, and others - and breaking down the underlying stocks within each fund. It reveals where your portfolio may unknowingly double down on certain holdings.

"The hidden concentration is such a good feature. Particularly for those in tech who already hold significant amount of company stock. They often forget those same holdings make up a large % of the indexes they hold." - Andre Nader, Author of FAANG FIRE

Mezzi's AI also suggests tax-aware rebalancing strategies, identifying the most efficient accounts to adjust first while minimizing tax impact. By connecting all your accounts through read-only access, Mezzi can flag wash sale risks and recommend the best sequence for achieving your target allocation.

Connecting Equity Compensation to Long-Term Goals

Equity compensation can play a pivotal role in achieving major life goals like buying a home, retiring early, funding education, or supporting charitable causes. The key is to synchronize your vesting events with these milestones, treating them as planned financial opportunities rather than unexpected bonuses.

Planning Around Vesting Schedules and Life Milestones

By aligning your vesting schedule with your long-term objectives, you can create a more structured approach to managing your equity. Each vesting event provides a predictable cash flow, which can be allocated toward specific goals. For instance, if you're a product manager aiming to purchase a $900,000 home in five years, you might allocate 40% of each RSU vest for a down payment while directing the remainder into retirement accounts or diversified investments.

A staggered selling strategy can also help you stay in a lower tax bracket, potentially preserving more of your funds. Mezzi’s Tax Optimization dashboard can alert you when shares qualify for long-term capital gains, providing additional tax-saving opportunities.

"Sell a stock at 11 months and you pay your ordinary income tax rate. Wait one more month and you pay the long‑term rate - often half as much." - Mezzi

Scenario Planning with Mezzi's AI

Making decisions about equity compensation often involves weighing multiple tradeoffs. For example, you might wonder how holding RSUs instead of selling them at vest could impact your retirement timeline or how exercising 2,000 ISOs this year might affect your AMT exposure and ability to maximize 401(k) contributions.

Mezzi’s AI can model these scenarios using your connected account data. It compares outcomes like selling 50% of shares at vest versus holding them, showing annual tax impacts, net worth projections, and retirement probabilities. This tool provides real-time insights tailored to your specific equity data, vesting schedule, and tax situation, helping you make informed decisions whenever questions arise.

Beyond tax and retirement considerations, your equity can also contribute to building a lasting legacy.

Charitable Giving and Legacy Planning with Appreciated Shares

Donating appreciated employer stock can be a tax-efficient way to support causes you care about. By donating shares directly, you avoid paying capital gains tax on the appreciation. If the shares have been held for more than a year, you may also qualify for a charitable deduction at their full fair market value, subject to IRS limits. This approach could help you bypass up to 20% in capital gains tax and an additional 3.8% Net Investment Income Tax on the gains.

For added flexibility, a donor-advised fund (DAF) can be a useful tool. Contributing a large block of appreciated shares during a high-income year - like when a significant tranche vests - allows you to claim an immediate deduction. You can then distribute grants to charities over time, aligning with your philanthropic goals while managing taxable income. Mezzi’s Tax Optimization tools can further assist by identifying the high-gain lots in your portfolio that offer the greatest tax benefits when donated, ensuring the timing aligns with your vesting schedule and income projections.

Conclusion: Take Control of Your Equity Compensation

To make the most of your RSUs and stock options, it’s crucial to understand your assets, anticipate tax events, and connect your equity to goals that matter to you. For senior tech employees, equity compensation can account for 50% or more of total pay. Ignoring it isn’t just risky - it may cost you significantly.

Using the strategies outlined earlier, take a proactive approach: understand your equity type and vesting schedule to prepare for tax events; plan with your marginal tax rate in mind to avoid surprises; keep employer stock exposure to 10%–15% to manage risk; and tie vesting proceeds to clear objectives, whether it’s buying a home or retiring early.

This is where Mezzi’s AI tools can help. By integrating your brokerage, equity, and retirement accounts, Mezzi provides real-time insights into your concentration risk, upcoming vesting events, and potential tax exposure. Instead of reacting to changes, you’ll be planning ahead.

Get started today: log into your equity portal, download your grant details, and link them to Mezzi. Set vesting alerts (30–60 days in advance) and explore scenarios like selling at vest or adjusting exercise timing to improve your after-tax outcomes. The key is consistency - not trying to time the market.

As Mezzi puts it:

"Tax Optimization finds opportunities throughout the year so there's less tax to report in April." - Mezzi

FAQs

How do I know if my RSU withholding is enough?

When companies withhold taxes on RSUs, they typically apply a flat 22% federal tax rate, along with any applicable state taxes. However, this one-size-fits-all approach may not match your actual tax bracket - especially if you experience a significant vesting event that boosts your income.

This is where Mezzi comes in. It gathers all your grant data, keeps tabs on vesting schedules, and compares the taxes withheld against your overall income. With its real-time analysis, you can evaluate whether adjustments to your W-4 or estimated tax payments might be necessary.

When should I exercise ISOs to avoid AMT surprises?

To reduce the chances of unexpected Alternative Minimum Tax (AMT) issues when exercising Incentive Stock Options (ISOs), consider these strategies:

• Exercise when the spread is small: The spread is the difference between the fair market value of the stock and the strike price. Exercising your options early - such as during the early stages of a startup or before a significant increase in valuation - can help keep the spread manageable.
• Spread exercises across calendar years: By spreading your exercises over multiple years, you may be able to keep your income below AMT thresholds, reducing the likelihood of triggering the tax.
• Exercise early in the year: Exercising early allows you more time to watch how the stock performs. If the stock's value declines by the end of the year, you might avoid AMT altogether, as the tax is based on the value at the time of exercise.

What’s the best way to sell employer stock without timing the market?

When it comes to managing vested shares, a systematic approach to selling them as they vest may help address emotional decision-making and reduce the risks tied to holding a concentrated stock position. Since taxes are generally triggered at the point of vesting rather than at the time of sale, selling the shares right away can limit exposure to capital gains fluctuations while also providing liquidity.

For those with access to material nonpublic information, using a 10b5-1 trading plan may offer a structured way to automate sales while helping ensure compliance with insider trading regulations.
