If you’re a founder or executive approaching a sale, an IPO, or an acquisition, you’ve likely spent years, maybe decades, building toward this moment. The company took shape through long nights and hard choices, and the equity you hold represents far more than a line on a balance sheet. It’s the accumulated value of a chapter of your life.
Then, on a single day, that value becomes liquid. A bank balance changes overnight, but here’s what experienced sellers consistently say afterward: the most valuable financial decisions were the ones made months before the closing date, while options were still open. Liquidity event financial planning is, at its core, the discipline of using that window well. Once the check arrives, many of the best strategies are no longer available.
The Window That Closes at Closing
The defining feature of pre-sale planning is reversibility. Before a transaction closes, you can still choose how to hold your shares, when to exercise options, what to gift, and how to structure what comes next. After closing, most of those choices are made for you.
When planning for an exit, one of the first things you should consider is who will be on your team. Choosing a financial advisor, a CPA, and a transaction attorney who are willing to collaborate and work together for your optimal outcome, helps produce…the optimal outcome. Then, understand what you actually hold. Founder shares, incentive stock options, non-qualified options, and restricted stock units each carry their own rules for timing and taxation, and the differences matter more as the dollars grow. If equity compensation is a significant part of your picture, our perspective on managing RSUs and stock options is a useful companion to this piece. For founders, there’s an additional question worth raising with your CPA early: whether your shares may qualify for favorable treatment as qualified small business stock, because eligibility depends on holding periods and company characteristics that can’t be fixed retroactively.
From there, the work is sequencing. Which options to exercise and when, whether to sell a portion of shares in a secondary offering, and how each choice interacts with the transaction timeline are decisions that deserve months of lead time, not weeks.
How Do Liquidity Events Affect Your Taxes?
Talk about this with your CPA early in the process. A liquidity event affects your taxes more than almost any other financial moment in your life, and the outcome depends heavily on decisions made before the sale.
The nature of your gain, how long you’ve held your shares, the state you live in when the transaction closes, and the calendar year in which income lands can each move the outcome meaningfully. For California founders and executives, the combined federal and state picture makes this planning especially consequential. Exercising incentive stock options can trigger alternative minimum tax considerations. A transaction that pays out over multiple years raises questions about installment treatment. Estimated taxes and withholding rarely keep pace with a windfall on their own.
None of this is a reason for alarm, and all of it is manageable with time. The right approach is to model scenarios with your advisor and CPA well before signing, so that the timing of exercises, sales, and even the close itself can be weighed deliberately. We’ve written about why tax planning works best as a year-round discipline rather than an April exercise, and a liquidity event is that principle at its highest stakes. The goal is not a guaranteed result. It’s walking into the transaction with your eyes open and your options understood.
Should You Update Your Estate Plan Before a Windfall?
Before is precisely when an update does the most good, and this is the opportunity most often missed.
Estate and gift strategies work on the value of what you transfer when you transfer it. Shares gifted or moved into a trust before a sale are valued as private company stock, often at a meaningful discount to what they’ll be worth once the transaction prices. Families who want to provide for children, fund education, or build multigenerational structures can accomplish more with the same shares before closing than after. These strategies involve real tradeoffs and real legal work, which is exactly why they belong in a conversation with your estate attorney months ahead of a letter of intent, not days.
The same logic applies to charitable intentions. Gifting a portion of appreciated shares to a donor-advised fund or another charitable vehicle before the sale can accomplish more for the causes you care about than writing a check afterward, because the gift carries the full appreciation with it. The mechanics take time, particularly with private company stock, and transactions already in motion can limit what’s possible. We covered how these vehicles work in Is a Donor-Advised Fund Right for You? Even the basics deserve attention in this window: documents, beneficiary designations, and titling should reflect your life as it is now, and an estate plan that hasn’t been revisited in years rarely does.
Who Belongs at the Table Before the Sale
A liquidity event is a team sport, and the team is larger than most sellers expect. Your M&A attorney or startup counsel runs the transaction. Your CPA models the tax picture. Your estate attorney handles structures and documents. Your financial advisor’s job is to connect all of it to your actual life, coordinating the specialists so their advice adds up to one plan instead of four.
Two seats are easy to overlook. The first belongs to your spouse or partner, because a liquidity event reshapes a family’s life, not just a portfolio, and decisions this large hold up better when both people understand them. The second is the quarterback role itself. In the months before a sale, your attention belongs on running the company and landing the transaction. Someone else should be watching the planning calendar, flagging deadlines, and making sure the pieces move in the right order.
The Check Is the Beginning, Not the End
The wire transfer feels like a finish line, but it’s really a starting line. The months after a liquidity event bring their own questions: how to invest a sum that arrived all at once, how to diversify away from the concentrated position that built the wealth, and what the money is actually for. Some sellers step into a work-optional life, a path we explored in what early retirement really requires. Others fund the next venture, take a real sabbatical, or redirect energy toward family and community. There’s no single right answer, and the plan should leave room for the answer to evolve.
What we’ve seen is that the sellers who feel settled a year after closing are the ones who did this thinking early. The wealth didn’t change them overnight, because they had already decided what it was for. We believe you create your legacy daily, and the months before a liquidity event are some of the most consequential days you’ll get.
If a sale, IPO, or acquisition is on your horizon, the best time to start planning is before the term sheet, and we’re here to help.
