If you work at a tech company in the Bay Area, there is a strong chance that equity compensation represents one of the largest and most complex pieces of your financial life. RSUs vesting on a quarterly schedule. ISOs or NQSOs sitting in a brokerage account. A growing concentration in company stock that has started to feel more like a risk than an asset.

The financial planning conversation around equity compensation is different from the standard investment management conversation. It involves tax strategy, concentration risk, retirement planning, and timing decisions that interact with each other in ways that require careful coordination.

This guide covers what you need to know about managing RSUs, stock options, and equity compensation as part of a long-term financial and retirement plan, with particular attention to the fourth quarter planning window that matters most for many Silicon Valley employees.

The Three Main Types of Equity Compensation

Before getting into strategy, it helps to understand how the most common equity compensation types differ.

Restricted Stock Units (RSUs)

RSUs are grants of company shares that vest over time according to a schedule, typically quarterly or annually over a three to four year period. When RSUs vest, you own the shares, and the fair market value of the shares at vesting is taxed as ordinary income, whether you sell them immediately or not.

This is the part that surprises many employees. You have a tax obligation on vesting day regardless of what you do next. If you hold the shares and the price drops before you sell, you still owe tax on the higher vesting day value.

For employees with meaningful RSU grants at major Bay Area tech companies, the tax exposure on a single vest date can be substantial. This makes the sell-or-hold decision, and the tax planning around it, one of the most important financial decisions many tech employees face each year.

Incentive Stock Options (ISOs)

ISOs give you the right to purchase company shares at a fixed price (the exercise price) at some point in the future. Unlike RSUs, ISOs don't create a regular income tax event when you exercise them, which makes them appealing. However, they do have important tax considerations.

For federal regular income tax purposes, exercising an ISO does not trigger ordinary income. But the spread between the exercise price and the fair market value at exercise is an Alternative Minimum Tax (AMT) preference item. Exercising a large ISO grant can trigger significant AMT liability, which is often a surprise.

If you hold the shares after exercise and meet the required holding periods, more than two years from grant date and more than one year from exercise, any gain on eventual sale qualifies for long-term capital gains treatment, which is generally more favorable than ordinary income rates.

Timing ISO exercises is one of the most consequential and nuanced equity compensation decisions for Bay Area tech employees.

Non-Qualified Stock Options (NQSOs)

NQSOs work similarly to ISOs in that they give you the right to purchase shares at a fixed price. The key difference is their tax treatment. When you exercise an NQSO, the spread between the exercise price and the fair market value is taxed as ordinary income in the year of exercise, regardless of whether you sell the shares. This creates an immediate tax event that ISOs avoid (though ISOs create AMT exposure instead).

NQSOs are generally more straightforward to plan around because the tax treatment is predictable.

Why Q4 Is the Most Important Equity Compensation Planning Window

For many Silicon Valley tech employees, the fourth quarter is the most consequential period of the year for equity compensation decisions.

Vesting schedules. Many companies structure RSU grants with quarterly vesting. The fourth quarter vest, combined with the three earlier vests, determines your total ordinary income from RSUs for the year. By October, you have reasonable visibility into what your total 2026 equity compensation income will look like, which creates the opportunity to plan around it.

Year-end tax planning. If you know your approximate income for the year, you can make smarter decisions about ISO exercises, capital gains harvesting, Roth conversions, charitable giving, and other year-end moves. The window between October and December 31 is when those decisions need to happen.

ISO exercise timing. If you're considering exercising ISOs, Q4 is often when the most careful analysis needs to occur. Exercising early in Q4 gives you time to model the AMT implications and understand the full tax picture before year end.

Concentration decisions. If you have accumulated significant holdings in company stock, Q4 is a natural time to evaluate whether your concentration level aligns with your financial plan and risk tolerance.

Concentration Risk: The Problem Nobody Wants to Talk About

One of the most consistent financial planning challenges we see with Bay Area tech employees is concentration risk, having a disproportionate share of total investable assets in a single company's stock.

This happens gradually and naturally. RSUs vest. You hold the shares because the stock has been performing well. You have a 83(b) election from an early ISO exercise that has grown significantly. Over time, one company's stock represents 50%, 60%, or even more of your liquid net worth.

Concentration isn't inherently wrong. Many Bay Area employees have built substantial wealth precisely because they held company stock through periods of strong performance. But it is a risk that deserves honest acknowledgment in any financial plan.

A few things worth considering:

Your human capital is already concentrated. Your salary, bonus, benefits, job security, and future equity grants are all tied to one company. Your investment portfolio being equally concentrated means your total financial life, earned income and invested wealth,  depends heavily on one outcome.

Diversification is a taxable event. Selling appreciated company stock creates a capital gain, which is one reason many people delay diversifying longer than they should. However, the tax cost of diversifying is often lower than the risk of maintaining concentration in a single name, particularly when that position represents most of a household's investable assets.

A systematic diversification strategy is usually better than a binary decision. Rather than selling everything immediately or holding indefinitely, a structured plan to reduce concentration over time, in a tax-efficient sequence, provides both risk management and better tax outcomes than either extreme.

How Equity Compensation Connects to Retirement Planning

For many Bay Area tech employees, equity compensation is not just a tax planning question. It's the primary mechanism through which they're building retirement wealth. Understanding how that wealth integrates with a long-term retirement plan matters.

Income replacement. If you're planning to retire or semi-retire in the next five to fifteen years, the wealth you're building through equity compensation may need to replace a significant income stream. How that wealth is structured: in taxable brokerage accounts, pre-tax accounts, or a Roth, will affect your tax picture in retirement for decades.

Account type diversification. Many tech employees have a significant concentration not just in company stock, but in a single account type, taxable brokerage accounts funded by RSU proceeds. Building balances across tax-deferred, tax-free, and taxable accounts creates flexibility in retirement that a single account type cannot provide.

Roth conversion opportunities. For tech employees who may have lower-income years in the future: sabbaticals, planned career transitions, the years between retirement and Social Security claiming, those periods can be excellent windows for Roth conversions that shift tax-deferred wealth into tax-free territory.

Estate planning implications. Concentrated stock positions have estate planning dimensions as well. Step-up in basis at death, charitable giving strategies using appreciated shares, and how concentrated positions factor into an overall estate plan are all worth coordinating with an estate planning attorney.

Questions to Ask Before Your Next Vest Date

If you have equity compensation vesting in Q4, these are the questions worth working through with a financial advisor before December 31:

• What will my total income from equity compensation be in 2026, and how does that affect my overall tax picture?
• If I exercise ISOs this year, what is my estimated AMT liability and how does it compare to holding until next year?
• Am I comfortable with my current concentration level in company stock? If not, what is a tax-efficient plan for reducing it over the next one to three years?
• Am I maximizing my 401(k) contributions, including any after-tax contributions that could be converted to Roth through the mega backdoor Roth strategy if my plan allows it?
• Do I have a plan for the proceeds from RSU sales or ISO exercises that coordinates with my long-term financial plan rather than defaulting to the brokerage account?

Frequently Asked Questions

What happens when my RSUs vest? 
When RSUs vest, the fair market value of the shares on the vesting date is included in your ordinary income and subject to federal and state income tax. This tax obligation exists whether you sell the shares immediately or hold them. Most employers withhold a portion of shares to cover taxes at vesting, but the withholding rate may not cover your actual tax liability, particularly if you're in a high income year.

Should I sell RSUs when they vest? 
The most tax-efficient approach for most employees is to sell RSUs promptly after vesting and redeploy the proceeds in a diversified investment strategy. Holding vested RSUs is equivalent to choosing to buy your employer's stock with after-tax dollars, and most financial plans benefit from diversification. However, the right answer depends on your tax situation, your concentration level, and your confidence in the company's long-term prospects.

What is the Alternative Minimum Tax and how does it relate to ISOs? 
The AMT is a parallel tax system that disallows certain deductions and adds back certain preference items, including the spread on ISO exercises. If your AMT liability exceeds your regular tax liability, you pay the AMT. For Silicon Valley employees with significant ISO grants, modeling AMT before exercising is essential to avoid unexpected tax bills.

How is equity compensation taxed in California?
California taxes all forms of equity compensation as ordinary income, with no preferential rate for long-term capital gains. This makes California's top marginal rate apply to RSU income, NQSO exercise spreads, and long-term capital gains on stock sales, which significantly affects the tax calculation for Bay Area tech employees.

What is concentration risk and how much is too much?
Concentration risk refers to having a disproportionate share of your investable assets in a single security. There is no universal threshold, but most financial planners consider having more than 10 to 15 percent of your portfolio in a single stock to be a meaningful concentration risk. For many Bay Area tech employees, company stock represents 50 percent or more of their liquid wealth, which warrants a deliberate diversification strategy.
