Estate planning for stock option holders is one of the most misunderstood areas of wealth planning for tech employees and executives. If your compensation includes incentive stock options (ISOs), nonqualified stock options (NSOs), or restricted stock units (RSUs), your estate plan must address how these assets are taxed, valued, transferred, or lost at death. Equity compensation does not behave like cash or publicly traded stock—and mistakes here are expensive.
This guide explains how different equity types are treated at death, common pitfalls for tech professionals, and how to coordinate option planning with your overall estate strategy.
Understanding the Three Main Types of Equity Compensation
Before planning, you must know what you actually own.
Incentive Stock Options (ISOs)
- Tax-favored options for employees
- Strict holding and exercise rules
- Limited transferability
Nonqualified Stock Options (NSOs)
- More flexible than ISOs
- Ordinary income tax upon exercise
- Common for executives and consultants
Restricted Stock Units (RSUs)
- Promise of stock upon vesting
- No exercise required
- Taxed as ordinary income when delivered
Each is treated differently at death—and those differences drive planning decisions.
What Happens to Stock Options at Death?
Here’s the hard truth: many options expire quickly after death.
Typical outcomes include:
- Unexercised options forfeited if deadlines are missed
- Vesting acceleration (sometimes)
- Forced exercise windows as short as 90 days
- Loss of favorable tax treatment
| Equity Type | Risk at Death |
|---|---|
| ISOs | Loss of ISO status |
| NSOs | Ordinary income tax |
| RSUs | Vesting rules vary |
| Unvested options | Often forfeited |
Your estate plan cannot override your equity plan documents.
Tax Treatment at Death: ISOs, NSOs, and RSUs
ISOs at Death
- No income tax at death if unexercised
- ISOs typically convert to NSOs when exercised by the estate or heirs
- Loss of preferential capital gains treatment
- Potential AMT exposure if exercised before death
NSOs at Death
- No step-up in income tax
- Ordinary income tax applies upon exercise
- Estate tax value includes option value at death
RSUs at Death
- Often vest or partially vest under employment agreements
- Taxed as ordinary income when shares are delivered
- Included in the taxable estate at fair market value
Key misconception:
Not all equity receives a clean step-up in basis.
Exercise Timing: A Critical Decision Point
Timing matters more than most tech employees realize.
Considerations include:
- Company liquidity (public vs private)
- Imminent IPO or acquisition
- Estate liquidity to fund exercise and taxes
- Risk of total forfeiture
In Silicon Valley and other tech hubs, families routinely lose seven figures by missing post-death exercise windows.
Planning may include:
- Pre-death exercises
- Liquidity reserves
- Life insurance to fund taxes
- Trust ownership structures (when permitted)
Vesting Acceleration Clauses
Some equity plans include:
- Death-based vesting acceleration
- Partial vesting
- Board discretion
Others do not.
Never assume acceleration applies. Your estate plan should:
- Reference equity plan terms
- Anticipate worst-case forfeiture
- Avoid relying on employer goodwill
Executives often discover vesting assumptions were wrong—too late.
Transferability Restrictions You Can’t Ignore
Most equity plans:
- Prohibit lifetime transfers
- Limit exercise to the employee or estate
- Restrict trust ownership
That means:
- You may not be able to “give” options away
- Trust planning must be coordinated carefully
- Beneficiary designations may be irrelevant
Estate planning works around these restrictions—not against them.
Valuing Unvested Options and Private Company Equity
Valuation is often the hardest part.
Private companies rely on:
- 409A valuations
- Liquidity discounts
- Vesting probability analysis
Unvested options may still have taxable estate value, even if they later forfeit. This creates a brutal mismatch between tax and reality.
Proper documentation and professional valuation matter.
Coordinating Equity With Your Overall Estate Plan
Stock options should not exist in a vacuum.
Effective coordination includes:
- Aligning beneficiary designations
- Providing executor authority to act quickly
- Funding taxes and exercises
- Balancing concentrated equity risk
- Integrating with trusts and marital planning
Florida residents benefit from:
- No state income tax
- No state estate tax
But federal tax exposure remains—and equity compensation often drives it.
Common Tech Scenarios
Scenario 1: Pre-IPO Engineer
Employee dies with unexercised ISOs. Estate misses the 90-day window. Options expire worthless.
Scenario 2: Public Company Executive
RSUs vest at death. Ordinary income tax is triggered. Estate lacks liquidity and must sell stock at an unfavorable time.
Scenario 3: Startup Founder
Unvested options included in estate value based on 409A, then later forfeited—creating phantom tax exposure.
These are planning failures, not bad luck.
Actionable Steps for Stock Option Holders
- Inventory all equity compensation annually
- Obtain and review plan documents
- Understand post-death exercise rules
- Coordinate liquidity for taxes and exercise
- Update estate planning documents accordingly

Frequently Asked Questions
Do stock options receive a step-up in basis at death?
Not always. Income components often do not.
Can my trust own my stock options?
Usually no. Most plans restrict ownership.
What happens if my estate misses the exercise deadline?
Options typically expire worthless.
Should I exercise options before death?
Sometimes—but this requires careful tax and liquidity analysis.
Call to Action
If equity compensation is part of your wealth, your estate plan must account for its rules, deadlines, and tax traps. Generic planning fails tech professionals every day. Work with a Florida estate planning attorney who understands ISOs, NSOs, RSUs, and the realities of modern tech compensation—before time, taxes, or forfeiture make the decision for you.
