Key takeaways
- Most windfalls are dissipated within a few years without a deliberate plan.
- Best practice: park the funds, assemble an advisory team, and defer major decisions for 60–90 days.
- Tax treatment varies wildly by source — inheritance, settlement, IPO, and lottery are each different.
- A windfall is also an estate-planning event — update beneficiaries, will, and trust accordingly.
How Olomon thinks about this
Olomon converts a windfall from chaos to structure: the inflow is captured, classified, and tied to advisors and documents. From day one, the household has a clear picture of what they actually have — the precondition for thoughtful, durable decisions.
In-depth definition
Windfalls compress decisions. A household that took 30 years to accumulate $2M of net worth might receive $5M in a single moment from a business sale or inheritance. Without a deliberate plan, the speed and emotion of that change overwhelm decision-making in predictable ways.
Frequently asked questions
Park the funds in a safe, FDIC-insured or Treasury-backed account, slow down, and assemble a CFP®, CPA, and — if material — an estate attorney before making any irreversible decisions.
