Your company just announced an IPO. It feels like a finish line, but it’s actually the start of a narrow planning window that can shape your financial future for years. The decisions you make before you can sell any shares will determine how much you keep, how much you lose to taxes, and how concentrated your wealth becomes. This guide walks you through the key steps to take now so you can turn equity into something durable and usable.
What you’ll learn
• How to get clear on what you actually own across RSUs, ISOs, NSOs, and shares
• What an IPO timeline really looks like, including lockups and selling restrictions
• How taxes apply to each type of equity and where most people get caught off guard
• How to think about exercising stock options before and after the IPO
• Why concentration risk matters and how to approach diversification
• How to build a plan for selling shares before the lockup expires
• How to align your equity decisions with the rest of your financial life
Why you should read this
Most employees treat an IPO like a moment to react. In reality, it’s a moment that requires planning. By the time a liquidity event arrives, many of the most important decisions have already been made, often without intention. This is where costly mistakes happen. If you want to avoid unnecessary taxes, missed opportunities, and overconcentration in one stock, you need a clear plan before anything becomes liquid.
With the right preparation, this moment can give you more control, more flexibility, and more options in your life and career.
Here’s the Scenario
The IPO announcement email hits your inbox.
Slack explodes. Valuation headlines start circulating. You open your equity portal and start doing mental math.
It’s exciting, as it should be.
But this is also one of the most financially sensitive moments of your career, and the decisions you make (or don’t make) in the weeks between announcement and actual liquidity can have consequences that last for years.
An IPO announcement is not a liquidity event. Not yet. It’s a planning window.
What you do between now and your first real opportunity to sell can determine how much you keep, how much you lose to taxes, how concentrated your wealth becomes, and whether this becomes long‑term financial freedom or long‑term regret.
Here’s What to Focus on Right Now
Don’t do anything emotional. Excitement is normal. However, financial decisions should not be emotional.
We see a predictable set of reactions every time an IPO is announced:
- Exercising all their stock options immediately without modeling the tax consequences
- Mentally spending money that isn’t liquid yet
- Assuming the IPO price is locked in or that they’ll be able to sell on day one
- Ignoring the gap between what taxes are withheld and what they’ll actually owe
- Not thinking about how much of their net worth is about to be tied to a single stock
All of this is understandable. None of it is a strategy. Right now, your job isn’t to act. It’s to get clarity.
The employees who treat this like a strategic planning event, not a lottery ticket, are the ones who convert equity into lasting wealth.
Step 1: Understand What You Actually Own
Before you can make any decisions, you need a complete inventory of your equity. Most employees have never seen all of their equity summarized in one place. That’s the first mistake and at a moment like this, it’s a costly one.
Pull everything together. Break it down by equity type, and get clear on the key details for each.
RSUs (Restricted Stock Units)
Start with the basics: how many are vested and how many are unvested? Then dig into the IPO‑specific questions.
Single‑trigger vs double‑trigger
- Single‑trigger RSUs only have a time‑based vesting condition and do not require a liquidity event (such as an IPO) to fully vest. Once the time‑based vesting condition is met, you own the shares and have already been taxed on that vesting, even while the company is private. Single‑trigger RSUs are more common in late‑stage private and public companies. In this case, your big tax events are usually at each vesting date, not at the IPO itself, because you’ve already been recognizing income along the way.
- Double‑trigger RSUs require both a time‑based vest and a liquidity event (like an IPO or acquisition). This type is the most common for companies IPO-ing. The units can be time‑vested on the company’s cap table but not fully vested or taxable to you until that second trigger happens. If you have double‑trigger RSUs, the IPO or liquidity event typically triggers a taxable vesting event on all your time‑vested shares at once (sometimes immediately, sometimes on a set date tied to the IPO). That can create a big W‑2 income spike in a single year.
Example:
- You’ve worked for your company for five years and over that time 10,000 RSUs have time‑vested.
- The company is about to IPO at $50 per share.
On the date your second trigger is satisfied (often IPO‑related), you recognize 10,000 × 50 = $500,000 of ordinary income. Typically, your company will do a sell‑to‑cover to withhold taxes.
For your unvested shares, ask:
- What does the vesting schedule look like post‑IPO?
- When will future RSUs vest, and how much income will each one generate at different stock prices?
Why this matters right now: RSUs are taxed as ordinary income when they vest. If the IPO or related trigger causes a large block of shares to vest in one year, you could be looking at tens or hundreds of thousands of dollars in taxable income, and the default withholding rate your company does almost certainly won’t cover what you actually owe.
Understanding the timing and size of these vesting events is the foundation of your tax plan.
ISOs (Incentive Stock Options)
Questions to answer:
- How many are vested and exercisable?
- What’s the strike price (purchase price) on each grant?
- When do they expire?
- Have you exercised any in prior years and if so, did you pay AMT?
- Do you have existing AMT credits from prior exercises?
ISOs have potentially favorable tax treatment, no regular income tax at exercise, but they come with real complexity.
- Exercising ISOs can trigger the Alternative Minimum Tax (AMT) based on the bargain element (the spread between your strike price and the stock’s fair market value at exercise).
- To qualify for favorable long‑term capital‑gains treatment, you must hold at least two years from grant and one year from exercise. If you sell before meeting both conditions, it’s a disqualifying disposition and more of the gain is taxed as ordinary income.
Why this matters right now: The IPO changes the math on when and how much to exercise.
- Exercising before the IPO usually means a smaller bargain element (since the 409A valuation is typically lower than the IPO price), which means less AMT exposure. But, you’re making a cash outlay on shares you can’t sell yet, and you’re betting the IPO actually happens.
- Exercising after the IPO can reduce AMT risk in many cases if you sell shortly after exercise, but be aware: selling quickly is a disqualifying disposition, which means you lose long-term capital gains treatment and most of the gain is taxed as ordinary income. The tradeoff needs to be modeled, not assumed.
These are timing and modeling decisions that need to be made before the IPO, not after. If you’ve already paid AMT in prior years, understanding your existing AMT credits is part of the picture too.
One strategy worth considering is spreading ISO exercises across multiple tax years to manage AMT exposure. If you have multiple grants with different strike prices, you can be strategic about which to exercise and how many, based on the current stock price and your projected income for each year.
NSOs (Non‑Qualified Stock Options)
Questions to answer:
- What’s the current spread between your strike price and the latest 409A valuation?
- When do they expire?
- How much ordinary income would be triggered if you exercised today?
NSOs are more straightforward than ISOs from a tax standpoint, but the bill can be heavier. When you exercise, the entire bargain element is treated like a paycheck:
- The spread (fair market value minus strike) is taxed as ordinary income and shows up on your W‑2.
- Federal withholding is typically at the 22% supplemental rate, but if the exercise pushes you into the 32–37% bracket, you’ll owe the difference at tax time. Add Social Security, Medicare, and state taxes on top.
Why this matters right now: You control the timing of NSO exercises, which is a powerful planning lever, but only if you use it intentionally.
- How many you exercise, in which year, and at what stock price all affect your tax bill.
- If you’re thinking about exercising during the lockup period, you’ll need cash on hand for both the exercise cost and the tax withholding, since you can’t sell shares yet to cover those costs. After lockup, a cashless exercise may be available, but during the lockup, it’s entirely out of pocket.
Another angle is monitoring stock price volatility and exercising when the price is near your strike price. If the stock is at $10 and your exercise price is $10, there’s no bargain element. This means no tax at exercise for either ISOs or NSOs. That’s the most tax‑efficient exercise possible. It doesn’t always happen, but being ready to act if it does is part of a good strategy.
For shares you already own, don’t forget:
- Shares from previous option exercises
- Shares received in earlier liquidity events or tender offers
Build your equity summary
Here’s the action item: build a simple equity summary spreadsheet. Create one document with every grant type, every grant date, every vesting schedule, every strike price, every expiration date, and every exercise you’ve already made.
If you don’t fully understand what you own, you can’t build a strategy around it. This single document becomes the foundation for every financial decision you’ll make over the next year.
This is tedious, but it’s the foundation. It is very common for people to discover:
- Options expiring next year that had almost been forgotten about
- Most RSUs don’t vest until after the IPO, causing some to mentally count money that isn’t real yet
You cannot plan around numbers you’ve only been carrying around in your head.
Step 2: Understand the IPO Timeline and Selling Restrictions
This is where people make expensive assumptions. The biggest misconception is thinking you can sell when your employer goes public. That may or may not be an option.
Start by getting clear on the basics:
- When is the expected IPO pricing date?
- What is the exact lockup period? It’s typically 180 days, but it varies by company and sometimes by employee classification.
- Are you subject to blackout windows?
- Are you considered an insider under your company’s policies or SEC rules?
- When are trading windows expected to open after the lockup expires?
Understanding the lockup is essential: this is a common post‑IPO restriction that prevents employees from selling shares for a set period. You can often still exercise (buy) your options during this period, but you typically can’t sell. That distinction matters enormously for cash‑flow planning.
Are you allowed to sell before or at the IPO?
This is a question most employees don’t think to ask, and it can materially change your planning.
Before the IPO, some companies allow employees to sell shares on secondary markets or through company‑facilitated tender offers. These opportunities are not available at every company, and they typically come with restrictions, but if your company has offered or is offering a pre‑IPO liquidity window, you need to understand the terms, the pricing, and the tax implications.
Selling pre‑IPO can provide early diversification and cash flow, but it also means selling at a price that may be below the eventual IPO valuation.
At the IPO, sometimes employees are allowed to sell a portion of their shares directly in the IPO offering (directed share programs or similar). If that’s available to you, find out:
- Are any of your shares eligible for sale at the IPO pricing?
- What percentage are you allowed to sell?
- Is it limited to vested shares only?
- Are there allocation limits?
- Do you have to elect to participate in advance?
- Are there minimum or maximum sale amounts?
- Are there company‑imposed restrictions beyond the standard lockup?
Do not assume in either direction.
You may have six months before you can sell anything, or you may have partial liquidity at IPO. The difference between those two scenarios is enormous from a planning perspective.
The key message is to never assume you can sell and never assume you can’t. Read everything your company’s legal and HR teams send you. Ask specific questions. Get written answers.
The difference between no liquidity for six months and selling 10–20% at IPO is massive for taxes, diversification, and cash planning. It’s worth getting clear, written answers.
What to look for in company communications
When a company files for an IPO, it usually rolls out new policies and FAQs for employees. They are not always easy to read.
Focus on a few key items:
- Lockup period – For a traditional IPO, you will likely be restricted from selling for a set period (often 90–180 days) after the IPO.
- Blackout windows – Even after the lockup, there may be quarterly blackout periods around earnings where you cannot trade.
- Pre‑IPO or early liquidity programs – Some companies allow limited sales before or shortly after the IPO to help employees cover tax withholding or diversify a small portion.
You want to be able to answer this question: When will I realistically be able to sell shares, and under what conditions?
Step 3: Start Tax Planning Before Liquidity Happens
Taxes are where IPO wealth quietly erodes. And the damage is almost always done before anyone realizes it because most equity‑related tax mistakes happen when planning starts too late.
Taxes don’t begin at filing time. They begin when income events occur. By the time you’re sitting with your CPA in April, the decisions that created your tax bill are already locked in.
An IPO does not change the basic tax rules, but it often changes the timing and size of your tax bills.
In practice, that means looking at three buckets: RSUs, options (ISOs and NSOs), and everything else in your tax picture.
RSUs
Once the company is public, RSU vesting becomes taxable W‑2 income. Companies typically withhold federal tax at 22%, the supplemental income rate. But if you’re in the 32%, 35%, or 37% marginal bracket (which IPO‑level equity income can easily push you into), that creates an automatic shortfall. Add state taxes on top, and you could be significantly underwithheld.
That’s how surprising five‑ and six‑figure tax bills happen. Not because anyone made a mistake, but because the default withholding rate doesn’t match the actual tax rate, and no one ran the numbers in advance.
What to do now:
- Identify large RSU vests in the same year as the IPO or shortly after.
- Roughly estimate the income they would create at different stock prices.
- Talk with a tax professional about whether you should plan extra withholding or estimated payments.
ISOs
There is no universally correct answer on when to exercise ISOs. There is only modeling and intentional decision making.
- Exercising before the IPO: smaller bargain element (lower 409A) and less AMT exposure, but you’re deploying cash into illiquid shares and betting the IPO or exit happens.
- After the IPO: often less AMT risk if you sell soon after exercise – but selling quickly is a disqualifying disposition, so you’d be trading long-term capital gains treatment for ordinary income. The right answer depends on your numbers.
The right move depends on:
- Strike prices vs expected IPO price
- Your current income and filing status
- Existing AMT credits
- How long you’re willing and able to hold
This is a modeling exercise. Run the numbers across multiple scenarios before making any decisions.
Strategy worth considering (re‑emphasized): spreading ISO exercises across multiple tax years to manage AMT thresholds. If you have multiple grants with different strike prices, you can be selective about which ones to exercise based on the current stock price and your projected income.
NSOs
The withholding at exercise (22% federal flat rate) almost always falls short of your actual marginal rate if the income from exercising pushes you into higher brackets. That gap becomes a tax bill at filing time and it catches people off guard every single year.
Strategies to consider:
- Spreading exercises across tax years to manage bracket creep
- Exercising in years where your other income is lower
- Coordinating exercises with income reducing strategies like maximizing retirement contributions
- Monitoring the stock price to exercise when the bargain element is smallest
If you exercise during lockup, remember you need cash for both the exercise cost and the immediate tax withholding. There’s no cashless exercise available until after lockup ends.
Don’t forget NIIT
If your modified adjusted gross income exceeds certain thresholds ($200,000 single, $250,000 married filing jointly), you may owe an additional 3.8% Net Investment Income Tax (NIIT) on your investment gains. At IPO income levels, this often applies. On its own it isn’t dramatic, but stacked on top of federal income tax, state tax, and possibly AMT, it adds up.
Tax planning should include:
- Multi‑year income projections across different stock price scenarios (IPO price, 30% higher, 40% lower)
- Estimated tax payment planning so you’re not caught short
- Withholding gap analysis for every RSU tranche
- Exercise‑timing strategies for ISOs and NSOs
- Coordination with other income events in the same year
The key principle: model before you make moves. Tax planning must happen before the income event, not during tax filing season.
Step 4: Prepare for Concentration Risk
Pre‑IPO, your equity feels theoretical.
Post‑IPO, it becomes a liquid, visible, real‑time‑priced asset and potentially 50%, 70%, or 80%+ of your entire net worth.
This gets tied to:
- The same company that pays your salary
- The same company that provides your health insurance
- The same company whose fortunes you already depend on for your career
That’s concentration risk, and it’s the quiet threat that most IPO employees don’t take seriously until it’s too late.
The mental traps are powerful and predictable
- I know this company better than Wall Street does.
- It just went public. It’s only going up from here.
- I’ll diversify later.
- Selling feels disloyal.
Concentration is how wealth is created. Overconcentration is how wealth is destroyed.
Get brutally honest about concentration risk
Rough exercise:
- Take a conservative estimate of what your company equity could be worth (not just the rosiest IPO scenario).
- Add it up across RSUs, options (at a reasonable assumed price), ESPP, and shares.
- Compare that to everything that is not in company stock: cash, retirement accounts, other investments.
Many people discover: 50–80% of their net worth is effectively one stock.
Ask yourself, “If this stock went to half its current value, would it meaningfully change my career options or major life plans?”
If the honest answer is yes, then diversification isn’t about not believing in your company. It’s about reducing the chance that one stock dictates your entire life.
One important framing
Diversifying doesn’t mean you’re bearish on the company. It means you’re building a portfolio that doesn’t require any single stock to perform well for your financial plan to work.
You can still hold a meaningful position. But it should be a deliberate position, not an accidental one.
This is about turning equity into durable, lasting wealth, not maintaining permanent concentration because you never made a deliberate decision.
Step 5: Build a Liquidity Plan Before the Lockup Expires
When lockups expire, things get chaotic. Volatility can spike. Employees rush to sell. Stock prices swing. Group psychology takes over in both directions.
The worst time to make a thoughtful financial decision is when everyone around you is making reactive ones.
Instead, pre‑decide. Before the lockup lifts, you should already know:
- How much do you need to sell to cover your tax obligations? This is non‑negotiable. The IRS doesn’t care about your lockup.
- How much do you want to sell for diversification? This should be based on your target allocation, not the stock price on the day the lockup expires.
- Do you want to retain a core long‑term position? If so, how large, and for how long?
- What price volatility can you tolerate? If the stock drops 30% the week the lockup ends, does your plan still work?
- What is your sell automatically strategy vs discretionary sales? Pre‑committed plans reduce the risk of emotional decision‑making.
Sketch a sell/hold framework before emotions take over
Define the purpose of this money. What do you want to achieve?
- Pay off debt?
- Buy a home or move cities?
- Create a bigger safety net?
- Support taking career risk in the future?
When you connect shares to real goals, decisions get clearer.
Create a simple policy, not a prediction. Here are some examples:
- Once I can sell, I will sell enough shares over the next 12–24 months to get my company stock down to no more than X% of my investable assets.
- Each time my RSUs vest after the IPO, by default I will sell at least Y% to diversify, unless something material changes.
- I will not let expiring options go unreviewed in the 12 months before expiration.
These are sample planning rules. You can adjust them later, but having them now keeps you from making decisions based only on what coworkers are doing.
Consider tools like 10b5‑1 plans and systematic selling
Some executives and employees use pre‑arranged trading plans (Rule 10b5‑1) to:
- Avoid trading while in possession of material non‑public information
- Spread sales over time to reduce timing risk and emotional decision‑making
Another approach is a systematic selling strategy, such as selling a set percentage of your shares every quarter after lockup to reduce concentration gradually. This avoids the pressure of trying to time the market and minimizes the emotional impact of stock price fluctuations.
The best liquidity decisions are made months before you’re allowed to act. The lockup period isn’t dead time. It’s planning time.
Step 6: Decide What to Do With Options Before They Sneak Up on You
Options are where people accidentally burn money by inaction.
Track expirations for each option grant. Write down the expiration date and set reminders 18, 12, and 6 months beforehand.
We routinely meet people who say, “I lost a nearly expiring grant because I thought I’d get a reminder. I didn’t.”
Think of Your Options in Buckets
Instead of one big blob, you might think about:
- High‑conviction, deep‑in‑the‑money options you’re inclined to keep and perhaps exercise gradually
- Marginal, close‑to‑the‑money options you’d only exercise if certain price or career conditions are met
- Low‑conviction, long‑shot options you might ignore unless the price moves a lot
Your exercise strategy should consider:
- Cash you’re willing to put at risk
- Tax consequences this year vs. future years
- How long you plan to stay with the company
Step 7: Coordinate the IPO With the Rest of Your Financial Life
An IPO‑related windfall (or potential windfall) doesn’t sit in a vacuum. It interacts with everything else.
Areas to revisit:
- Emergency fund and cash buffer: If most of your safety net is company stock, consider whether you actually have a usable buffer.
- Debt: Would it be wise to reduce high‑interest debt when liquidity becomes available?
- Housing: If you’re thinking about buying a home, coordinate down‑payment timing with lockup expiration and tax payments.
- Retirement savings: Use the IPO as a moment to bring retirement accounts, equity comp, and taxable accounts into one coherent plan.
- Career flexibility: Some people use IPO liquidity to take career risk (joining an earlier‑stage company, starting something, scaling back hours). Planning that in advance matters more than squeezing the last dollar out of the stock.
The real value is not the number on paper. It’s the options it creates in your life.
An IPO can create life changing wealth, but only if you handle it intentionally. Without a plan, it is easy to overpay in taxes, take on too much risk, or make emotional decisions at the worst possible time. With the right preparation, this moment can give you more control, more flexibility, and more options in your life and career.
What you just learned
- An IPO is a planning window, not immediate liquidity, and timing matters more than most people realize
- You need a clear inventory of your equity to make informed decisions across RSUs, ISOs, NSOs, and shares
- Taxes often create the biggest impact, especially when planning starts too late or withholding falls short
- Concentration risk can quietly build, making diversification a necessary part of turning equity into lasting wealth
- A defined liquidity and exercise strategy helps you avoid emotional decisions when volatility and lockups come into play
