The first 90 days after a liquidity event are the most important to set the right foundation and preserve your optionality. The priority isn’t making decisions, it’s inventorying the situation, understanding taxes, coordinating with your advisory team, and making sure key deadlines aren’t missed. Enter the post-liquidity planning checklist.
This checklist focuses on immediate actions in the first 90 days after a liquidity event. Longer-term priorities are covered in our guide on what should you do with a windfall, which is better suited to bigger-picture decisions in months 4-12. For support throughout the post-liquidity transition and help managing your new financial reality, work with a sudden wealth financial advisor.
1. Don’t make major decisions yet
Try to avoid the pressure to spend or allocate money quickly or make big personal decisions right away. In most cases, a pause is necessary to fully understand your options.
Instead of inaction, it’s about resisting the urge to make irreversible decisions before you understand the whole picture and alternatives. This includes avoiding:
- Making investment decisions without a plan
- Paying off a mortgage right away
- Committing to major purchases
- Making changes based on emotion, excitement, or pressure from others to have a certain lifestyle
The key is to preserve flexibility while you gather the information you need. You can only spend a dollar once!
2. Confirm what you have: liquid cash versus paper wealth
Not every liquidity event is the same. Some come in cash while others involve stock, rollover equity, earn-outs, deferred payments, lock-up periods, or a mix of a few. So when considering your liquidity, remember that your brokerage account or stock plan balance isn’t the same as your bank account balance.
Start by identifying:
- What was sold and what cash you actually received
- What was transferred to another account
- What portion, if any, remains tied to earn-outs, performance-based milestones, vesting, or other nonguaranteed forms of payment
- Whether any part of the total value you expect to receive is subject to lockups, restrictions on selling, hedging or pledging, or similar limitations
This step matters because the word “liquidity” can be misunderstood. A gross figure isn’t the same as your usable net proceeds after taxes, tie-ups, and valuation changes.
After confirming your true liquidity, protect yourself while you tackle the other checklist items. This includes considering FDIC limits and holding cash in accounts that are harder to access by scammers (pro tip: your checking account is not the safest place).
3. Estimate your after-tax proceeds
One of the biggest mistakes after a liquidity event is mistaking a gross number for a net figure. In reality, the after-tax amount may be meaningfully different.
Your actual tax exposure depends on the type of event, structure, and the type of assets involved. You shouldn’t assume that any tax withholding covers the final bill. In many cases, it does not. A number of different types of taxes may apply:
- Federal income tax
- State income tax
- Capital gains tax (short or long-term)
- Employment-related withholding (potentially at supplemental rates)
- Estimated tax payments
- Payroll tax
- Federal, state, and local surtaxes
- Other taxes based on your situation
A good early step is to work with your tax professional or financial advisor to understand:
- Expected tax liability
- Net proceeds after tax
- A timing mismatch between when you receive the cash and when taxes are due
Net proceeds should become the foundation for every other decision you make.
4. Set aside cash for taxes first
After a liquidity event, cash can disappear quickly if it is not earmarked with purpose. Before you commit money to lifestyle spending, investing, gifting, or other goals, set aside the amount you may need for taxes.
In most cases, after a large liquidity event, you will need to make estimated payments (due in April, June, September, and January) and have a balance due in April of the following year.
Taxes can create big liquidity issues without proper planning. Although there are ways to access cash in a pinch, such as a securities-backed line of credit on a brokerage account, it’s typically best to set aside money for known tax liabilities in advance. Treasury ladders can be a great way to earn interest without risking your principal (assuming you hold the bond to maturity).
5. Review concentration risk
After an on-paper liquidity event, concentration risk can remain. Post-IPO or stock acquisition investment risk is in held shares. For entrepreneurs selling a business, rollover equity, earn-outs, installment sales, or recapitalizations can still tie a meaningful share of your net worth to one company.
Understanding your undiversified risk is important before finalizing your financial plan or making big purchases. Spending too heavily before proceeds are diversified and secure puts your financials at risk.
Questions to ask include:
- Do I still hold a meaningful position in the company?
- Is any of my wealth still dependent on the company’s future performance?
- If I received cash instead of stock, how much of this company’s stock would I buy?
- Does reducing risk now create a tax tradeoff I should understand first?
- Does my strategy to manage taxes expose me to too much volatility and risk in the process?
You do not need to solve diversification overnight. But you should understand what level of concentration still exists and what options you have to manage it.
6. Update your balance sheet and account inventory
A liquidity event can change not just your net worth, but the way your financial life is organized. That makes it a good time to refresh your financial snapshot.
At a minimum, review:
- Accounts and balances
- Account titling and ownership
- Beneficiary designations
- Cash reserves
- Debts
- Insurance coverages
- Equity compensation or transaction-related documents
- Estate planning documents
A big part of this post-liquidity checklist is getting organized and taking stock of your current situation. So resist the urge to make changes at this step. Once you’re past the immediacy of the liquidity event, you’ll progress into planning and decision-making.
7. Inventory your goals
Once the immediate administrative issues are addressed, the next question is more personal: what is this wealth supposed to do?
That answer doesn’t need to be finalized in the first week. But it should be pretty clear before you make major decisions.
Common goals include:
- Maintain flexibility
- Build a diversified long-term portfolio
- Pay off debt
- Fund college education expenses
- Support for family members
- Charitable giving
- Build a legacy for your kids
The key is to connect money to your purpose. As you make your financial wish list, try to prioritize it by level of importance and urgency.
First 90 days: planning outline
You do not need to solve every decision immediately and the goal isn’t to try. A better approach is to sequence the work over time.
First 30 days
- Confirm proceeds
- Estimate taxes
- Set aside cash for taxes
- Gather key documents
- Coordinate advisors
- Move proceeds to a safe, interest-bearing account
- Don’t make any big financial decisions to protect your optionality
Days 31–60
- Review concentration risk
- Update or create your financial and account inventory
- Locate and review your current estate plan to understand the current structure and beneficiary designations
- Consider your goals for the proceeds (short, medium, and longer-term)
- Review cash flows and expenses
Days 61–90
- Start considering changes and next steps in implementation
- Develop a longer-term planning framework, with flexibility
- Address any remaining investment, estate, or tax planning work
- Identify next steps in the financial planning process
A time-based plan can reduce pressure and make the transition feel more manageable.
Common mistakes to avoid after a liquidity event
A large financial event can create a false sense of security. In practice, some of the biggest mistakes happen after the money arrives.
Watch out for:
- Spending before you understand the tax bill
- Assuming withholding is enough
- Overestimating what you have
- Locking up too much liquidity in the purchase of a home
- Not considering the opportunity cost of paying off low rate debt
- Ignoring the risks of paper portfolio wealth and stock concentration, one of the top post-IPO mistakes
- Failing to update estate documents if you decide changes are necessary
- Making decisions without coordinating advisors or professional support entirely
Avoiding these mistakes can matter more than chasing a perfect allocation strategy right away.
The bottom line
The term liquidity event implies a one-time milestone, when it’s actually a longer-term transition. The first 90 days are usually about stabilization and organization: understanding what you have, safeguarding cash, estimating taxes, reviewing risk, and building a framework for the implementation phase.
Approaching the process with patience and coordination will provide you with more flexibility down the line and help you avoid unwanted and unnecessary surprises.
Common Questions About What to Do in the First 90 Days Post-Liquidity
After a cash liquidity event, the first step is making sure the money is kept in a secure account. Then, avoid major purchases until you’ve had time to process the change and assess the tax implications.
The waiting period will depend in part on how long it takes you to answer the immediate questions around taxes and goals. Waiting at least 90 days is usually ideal. Bigger decisions should come after advisor coordination and financial planning which happens a few months after the actual liquidity event.
The basis post-liquidity advisory team includes a sudden wealth financial advisor, CPA or tax advisor, and estate planning attorney.
