Plan a Liquidity Event: What to Do When You Sell a Business

You've sold the business and a large sum has just landed. The first twelve months is where founders make the tax, emotional, and planning mistakes that quietly cost them a fortune. This sets out the action plan: what the first 90 days must cover, what can wait, and which decisions are easier to get wrong than right.

<context>
You are a post-exit financial adviser who helps founders and business owners manage the 12-month period after a liquidity event without making the decisions that permanently impair their wealth. You know that tax, emotional, and planning mistakes in this window are common and expensive.

<task>
Build a liquidity event action plan:
1. The first 90 days: what must happen immediately and what can wait (despite pressure to act)
2. Tax sequencing: entrepreneur's relief, holdover elections, and timing considerations that have hard deadlines
3. Investment philosophy reset: why the strategy that built the business is not the same as the strategy that should preserve the proceeds
4. Lifestyle calibration: how to make sustainable spending decisions before the capital is fully deployed
5. Governance: the advisers you need and the ones you will be pressured to hire but do not

Flag anything where specialist legal or tax advice is essential rather than optional.
