Why This Strategy Exists
High income, real dollars at stake, and enough complexity that a generic return won't cut it
Every major tax strategy is just the government's way of paying you to behave in a certain way: provide housing, hire people, save for retirement, or structure your business cleanly.
Equity Compensation is designed for situations like yours: high income, real dollars at stake, and enough complexity that a generic tax return won't cut it. It sits inside a broader plan: see our wealth-building strategy hub and our service levels.
The Risk of DIY
This strategy gets thrown around online as a magic bullet. The reality: the IRS is very specific about who qualifies, what documentation is needed, and how it must be reported.
Most of the messes we clean up come from half-implemented versions: no logs, no elections, no support, and big deductions that fall apart under scrutiny.
The Taxstra Approach
We don't treat this as a party trick. We treat it as an engineering project: understand your situation, model the numbers, then build a checklist so every requirement is met intentionally. That includes time logs, elections, entity structure, coordination with attorneys or cost segregation firms when needed, and clear expectations for how the strategy evolves over time.
The Core Rules You Can't Ignore
How it works, the non-negotiables
Every strategy has a handful of non-negotiables. Get these right, and you're usually fine. Miss them, and no amount of clever structuring will save the deduction.
- Eligibility. Who can actually use Equity Comp Planning, and who should not try. We map your income mix, entities, and long-term goals before we ever recommend it.
- Key Tests. Hour thresholds, income limits, material participation tests, or dollar caps. We translate legalese into plain-English checklists specific to this strategy.
- Documentation. What needs to be logged, signed, or saved: calendars, receipts, minutes, elections, appraisals, or engineering reports: whatever the IRS expects to see later for Equity Comp Planning.
Before you exercise or sell, run the AMT calculator for ISO exercises and the RSU tax calculator.

The Technical Deep Dive
ISOs, NQSOs, RSUs, the 83(b) election, and who this is NOT for
Equity compensation comes in many flavors: ISOs (Incentive Stock Options), NQSOs (Non-Qualified Stock Options), and RSUs (Restricted Stock Units). Each has a unique tax trigger.
The "Holy Grail" is the 83(b) election for restricted stock, which allows you to pay tax on the current value (often near zero for startups) and treat all future growth as capital gains. For ISOs, the battle is managing the AMT spread; see our AMT planning guide for how that calculation works.
Who This Is NOT For
Risk Averse. Holding stock in a single private company is high risk. Sometimes paying the tax and diversifying is the smarter financial move.
Short Timers. If you leave before your vesting cliff (usually 1 year), you get nothing. Tax planning is moot.
Your Implementation Checklist
The steps, in order
| Step | Action | What It Involves |
|---|---|---|
| 01 | Review Grant Docs | Understand exactly what you have (ISO vs NQSO vs RSU) and the vesting schedule. |
| 02 | File 83(b) | If eligible (early exercise/restricted stock), file the 83(b) election with the IRS within 30 days of grant. |
| 03 | Model Exercise | Calculate the cash needed to exercise and the projected tax hit (including AMT for ISOs). |
| 04 | Plan Exit | Decide on a liquidation strategy. Will you hold for 1 year (LTCG) or sell immediately (Ordinary Income)? |
Day in the Life: The IPO
How option planning plays out from grant to exit
1. Year 1: The Grant
You join a startup. You get 100,000 ISOs at $0.10 strike price. Action: You file an 83(b) election (if eligible) or plan your early exercise.
2. Year 3: The Exercise (AMT Trap)
The company is doing well. FMV is now $5.00. You exercise 10,000 shares. The Math: You pay $1,000 to buy them. But the IRS sees a "paper profit" of $49,000. This triggers AMT. You owe $14,000 in tax on money you haven't received yet.
3. Year 5: The Exit
IPO! Stock hits $50. You sell your shares. Result: Because you held for >1 year after exercise, your $500,000 gain is taxed at 20% (LTCG) instead of 37% (Ordinary Income). You saved $85,000 in tax.
4. The Credit
Remember that AMT you paid in Year 3? Now you get it back as a credit against your regular tax, reducing your bill even further.

Equity Compensation (ISO/NSO/RSU) Planning FAQ
Common questions before pulling the trigger
What is the difference between ISOs and NQSOs?
ISOs (Incentive Stock Options) offer potential tax advantages (capital gains rates) but come with AMT risk. NQSOs (Non-Qualified Stock Options) are taxed as ordinary income (like a bonus) when you exercise them. The planning for each is completely different.
Why is the 83(b) election so important?
It allows you to pay tax on the value of your stock *today* (often very low for early startups) rather than when it vests later at a higher value. It can save millions in tax, but you strictly have 30 days from the grant date to file it.
Will exercising ISOs trigger AMT?
It depends on the 'spread' (difference between strike price and fair market value) and your other income. We run a specific AMT projection to tell you exactly how many options you can exercise before hitting the AMT tipping point.
Should I sell my RSUs as soon as they vest?
From a tax perspective, there is usually no benefit to holding RSUs after they vest. You've already paid the ordinary income tax. Holding them is just a bet on that single company stock. Diversification is often the wiser move.
What happens if I leave the company?
You usually have 90 days to exercise your vested options or you lose them. This 'golden handcuffs' problem requires immediate cash and tax planning to decide if it's worth buying the stock.
Can I use secondary markets to sell pre-IPO stock?
Sometimes, via platforms like Forge or EquityZen, but you need company approval (ROFR). This can provide liquidity to pay taxes on exercise, but it triggers a taxable sales event immediately.
What is QSBS (Section 1202)?
If you hold stock in a Qualified Small Business (C-Corp with <$50M assets) for 5+ years, you might pay 0% federal tax on the gain (up to $10M). This is massive for startup founders and early employees.
Does my state tax equity comp differently?
Yes. California, for example, does not recognize the Federal exclusion for ISOs or QSBS. You might owe 13.3% state tax even if you owe 0% federal. State-specific planning is critical.
What are 'double-trigger' RSUs?
Common in pre-IPO companies. Vesting requires two events: (1) Time (working there 4 years) AND (2) Liquidity Event (IPO/Acquisition). You don't owe tax until BOTH happen, which usually means a massive tax bill in the year of IPO.
