The irony of equity compensation is that the more you accumulate, the harder it is to make decisions.
Do you sell vested RSUs immediately or hold for potential upside?
When does exercising options trigger an AMT liability?
How much of your net worth is concentrated in a single stock? At what point does that become a problem?
Meanwhile, work is busy, life is busy, and the decisions are complicated enough that answering these questions tends to slip down the priority list.
But complexity doesn’t resolve itself. Blackout windows close selling opportunities you’d been waiting for. Vesting events spike your income into brackets you weren’t prepared for. The concentrated position you meant to unwind has become the majority of your liquid net worth. What started as the most valuable component of your compensation package has become the most neglected part of your financial plan.
At some point, the question worth asking isn’t just how to manage your company shares. It’s what you’re actually accumulating them for.
The Three Most Common Forms of Equity Compensation
Before getting into decision-making, it helps to establish a baseline understanding of different types of equity compensation. Most executive compensation packages include some combination of the following:
| Type | How It Works | Tax Trigger |
| Restricted Stock Units (RSUs) | Company stock granted on a vesting schedule; converts to shares once conditions are met | Ordinary income tax at vesting on fair market value |
| Stock Options (ISOs and NSOs) | Right to purchase shares at a fixed strike price; ISOs for employees only, NSOs broader in scope | NSOs: ordinary income at exercise
ISOs: potential long-term capital gains if holding requirements met |
| Employee Stock Purchase Plans (ESPPs) | Purchase company stock at a discount (typically 10–15%) via payroll deductions; many plans include a lookback provision | Depends on holding period; qualifying dispositions receive more favorable treatment |
Each works differently, taxes differently, and involves different decisions. The sections that follow address each one in turn.
RSUs: The Most Common Mistakes
RSUs can be a lucrative incentive, but they aren’t necessarily straightforward to manage. Here are the most common mistakes:
The withholding gap. Most employers withhold taxes on RSUs at a flat 22% supplemental rate. For executives earning $300,000 or more, the real federal marginal rate is 35% or higher — a sizable disparity. On a $50,000 vesting event, that’s a $6,500 federal shortfall that may come as a surprise at filing. Multiply that across multiple vesting tranches and it compounds quickly. Options for closing the gap:
- Request supplemental withholding from your employer
- Set aside the estimated shortfall in cash
- Make estimated tax payments if the anticipated shortfall is significant
The cost basis error. When RSUs vest, the income appears on your W-2. When you later sell, your brokerage issues a 1099-B reporting proceeds — but not necessarily the cost basis. If you don’t report the fair market value at vesting as your cost basis on Schedule D, the IRS assumes the entire sale proceeds are a taxable gain. Always confirm your return accurately captures the cost basis of every vesting event.
Single stock concentration. Your financial life is already tied to your employer through your salary, benefits, and career trajectory. Holding a significant amount of vested RSU shares amplifies that exposure. A useful benchmark: no single stock position should exceed 10% of your liquid net worth. Historical data reinforces why — a study analyzing Russell 3000 returns over a 40-year period found that 40% of stocks experienced a peak-to-trough decline of 70% or more.
The wash sale trap. If you sell company stock to harvest a loss and RSUs vest (or you repurchase shares of the company) within 30 days before or after the sale, the wash sale rule disallows the loss for tax purposes. This can catch executives off guard, particularly when automated transactions like RSU vesting and ESPP purchases are running in the background.
Stock Options: ISOs, NSOs, and the Exercise Decision
There’s more active decision-making involved with stock options than RSUs, and the tax implications vary significantly depending on the type you hold.
| Non-Qualified Stock Options (NSOs) | Incentive Stock Options (ISOs) | |
| Who receives them | Employees, directors, contractors | Employees only |
| Tax at exercise | Ordinary income on spread | No ordinary income tax; AMT may apply |
| Tax at sale | Short or long-term capital gains on appreciation post-exercise | Long-term capital gains if holding requirements met |
| Holding requirements | None | 1 year from exercise, 2 years from grant date |
| AMT exposure | No | Yes — bargain element counts as AMT income |
Exercising NSOs
At exercise, the spread (also known as bargain element) between your strike price and fair market value is taxed as ordinary income — and the 22% default withholding likely won’t cover your actual liability if you’re in a higher bracket. If you exercise 1,000 NSOs with a $50 strike price when the stock is at $75, you recognize $25,000 of ordinary income in that year regardless of whether you sell. Any appreciation after exercise is taxed as capital gains at sale.
Exercising ISOs
ISOs offer the potential for long-term capital gains treatment on the full gain, but the alternative minimum tax (AMT) is the complication most executives underestimate.
The AMT functions like a shadow tax system: a separate calculation running in the background that most people never notice unless it directly affects them. It recalculates your liability by adding back certain items the standard system excludes, including the bargain element from ISO exercises. If the AMT calculation produces a higher number than your regular tax bill, you pay the difference.
The silver lining is that AMT paid generates a credit that carries forward indefinitely to offset future standard tax liability. It doesn’t eliminate the liability, but it isn’t lost either.
Timing considerations
- The 90-day rule. If you leave a company, most ISO grants must be exercised within 90 days or they convert to NSOs, losing the favorable tax treatment permanently. If you’re considering a job change and hold in-the-money ISOs, the timing around your departure should be considered carefully.
- Private company options. Exercising options in an illiquid company means taking real cash risk on an asset with an unclear path to liquidity. The calculus is fundamentally different than at a public company.
- Early exercise. Exercising while the valuation is still low (and filing an 83(b) election within 30 days) starts the holding period clock earlier and can reduce the AMT exposure significantly.
ESPPs: How They Work and When to Sell
Employee Stock Purchase Plans (ESPPs) allow employees to purchase company stock at below-market prices through regular payroll deductions — a simple concept that still has tax consequences.
How they work:
- Contributions are made through payroll deductions over a defined offering period
- Shares are purchased at a discount, typically 15% below fair market value
- Plans with a lookback provision apply the discount to the lower of the stock price at the start or end of the offering period, potentially amplifying the built-in advantage significantly
For example, if the stock is $100 at the start of the offering period and $120 at the end, the lookback provision means you purchase at $85 — 15% below the $100 starting price, not the $120 ending price. You’ve generated a $35 gain per share before the stock moves another dollar.
Tax implications
The tax treatment of ESPPs depends on the period of time you hold the shares after purchase. The distinction between a qualifying and disqualifying disposition can materially affect your after-tax proceeds.
| Disposition | Holding Requirement | Tax Treatment |
| Qualifying | 1 year from purchase, 2 years from offering start | Discount taxed as ordinary income; remaining gain at long-term capital gains rates |
| Disqualifying | Sold before meeting holding requirements | Entire gain taxed as ordinary income |
In most instances, selling ESPP shares promptly after purchase is the cleaner move. The guaranteed discount is valuable, the tax treatment on an immediate sale is manageable, and holding to qualify for better tax treatment introduces stock price risk that may not be worth it.
The Concentration Problem
All three forms of equity compensation, left unmanaged, tend to produce the same outcome: a portfolio disproportionately concentrated in a single company’s stock.
At large public companies, particularly in tech, it’s not unusual for a senior executive to hold all three simultaneously. RSUs are standard at most levels, stock options are frequently part of C-suite packages, and ESPPs are widely available as an employee benefit. The result is multiple layers of single-stock exposure stacked on top of employment income that’s already tied to the same company’s performance.
The worst-case scenario isn’t pretty: the company struggles, share prices drop, and layoffs follow. For a C-suite executive, the double shock can be especially pronounced, considering company equity typically represents a larger proportion of total compensation at the senior level, and finding a comparable role takes time. Both your income and your portfolio take a hit simultaneously.
Tools for managing concentration deliberately:
- 10b5-1 plans. A prearranged selling schedule established during an open trading window that executes automatically, including during blackout periods, insulating you from the appearance of trading on material nonpublic information. For executives with significant single-stock exposure, this is often the most practical path to systematic diversification.
- Systematic sale strategies. Spreading sales across multiple years to smooth taxable income and avoid bracket spikes.
- Donor-advised funds. Funding a DAF with appreciated shares removes the position from your portfolio, generates a deduction at fair market value, and avoids recognizing the capital gain entirely. Particularly effective in high-tax states like California, where capital gains are taxed at the same rate as ordinary income.
- Exchange funds. Allow you to contribute appreciated shares into a diversified fund without triggering an immediate taxable event — a useful tool for executives with very large concentrated positions.
The Question Underneath the Numbers
The technical decisions around equity compensation are important. So is the question that lingers underneath them.
I’ve worked with executives who managed their options and RSUs efficiently for years — exercised at the right time, diversified strategically, minimized taxes — and still arrived at the next chapter of their lives with a portfolio that wasn’t pointed at anything in particular. Their financial plan was crystal clear. Their life plan was murky, at best.
At Five Oceans, the equity compensation conversation is always part of a larger one. How much concentration risk are you willing to expose yourself to? What does the transition out of your career look like, and are you building toward it deliberately?
Those are Life Strategy questions. And they’re worth asking alongside the technical ones.
