How to Deal With an Unexpected Cash Windfall
Winning money. Receiving an inheritance. Business sale. Selling shares. A redundancy package.
Whatever the source, a cash windfall often arrives with a mix of excitement — and pressure.
At Fortitude Financial Planning, we regularly meet people who tell us the same thing: “I don’t want to make a mistake with this money.”
That’s completely normal. A cash windfall can be life-changing, but only if it’s handled with clarity and intention.
This article outlines a calm, structured approach to help you make confident decisions.
Step 1: Take a Breath Before Making Any Decisions
A sudden windfall can create emotional noise — excitement, guilt, worry, even a sense of responsibility.
The best first step is to pause.
-
Don’t rush into investments.
-
Don’t feel pressure to help others immediately.
-
Don’t make big purchases in the first few days or weeks.
Giving yourself time allows the emotional dust to settle so decisions are made from clarity, not impulse.
Step 2: Understand the Tax Implications
In Ireland, the tax impact of a windfall can vary hugely depending on the source:
-
Inheritance or gift → May be subject to Capital Acquisitions Tax (CAT), depending on thresholds.
-
Redundancy payment → Some may qualify for tax-free statutory redundancy, but lump sums above limits may be taxable.
-
Prize winnings → Often tax-free, but subsequent investment returns are not.
-
Share sales or property proceeds → Capital Gains Tax (CGT) applies.
A quick conversation with a financial planner and tax adviser avoids surprises and can identify opportunities to legally reduce or manage tax.
Step 3: Strengthen Your Foundation First
Before thinking about investing or spending, check three essentials:
1. Emergency Fund
Do you have 3–6 months of living costs easily accessible?
A windfall is a perfect opportunity to strengthen this cushion if needed.

2. High-interest debt
Credit cards, loans, or overdrafts often charge double-digit interest.
Clearing these can be one of the best, guaranteed “returns” you’ll ever get.
Step 4: Align the Money With Your Long-Term Goals
This is where clarity matters most.
Ask yourself:
-
What do you want this money to do for you?
-
Is this about financial security?
-
Accelerating retirement?
-
Helping your children?
-
Reducing stress or buying freedom?
-
Investing for long-term growth?
A cash windfall becomes far more powerful when it’s attached to a purpose.
Step 5: Invest With a Strategy, Not a Reaction
Many people feel pressure to “put the money to work” quickly, but investing without a plan can be riskier than doing nothing.
When we help clients invest a windfall, we look at:
-
Their capacity and tolerance for risk
-
Their time horizon
-
Their need for access to the funds
-
Their long-term objectives
-
Tax efficiency
Often the correct strategy is a globally diversified portfolio, aligned with your personal risk profile and rebalanced over time — not a rush into what’s currently fashionable.

Step 6: Avoid the Most Common Windfall Mistakes
Over the years, we’ve seen the same pitfalls come up again and again.
Here are the big ones to avoid:
1. Making big purchases too quickly
Initial excitement can lead to decisions you might rethink a month later.
2. Lending or giving money out of guilt or pressure
Healthy boundaries matter — your windfall should support your life first.
3. Trying to “beat the market”
Jumping between ideas or trends often leads to poor long-term outcomes.

4. Not planning for future tax
For example, keeping everything in a standard bank account may be simple but could be inefficient.
5. Holding too much in cash for too long
A very common reaction to a windfall is to “park it in cash for now.”
While this feels safe, over time inflation quietly erodes the real value of your money.
In Ireland, when inflation runs at even 3–4% a year, €100,000 of uninvested cash can effectively lose €3,000–€4,000 of purchasing power annually.
Cash absolutely has a place — particularly for your emergency fund and short-term goals — but a windfall that sits idle for years can shrink in real terms without you noticing.
6. Not coordinating decisions
Investments, tax, estate planning, and cash flow all interact — consistency is key.
Step 7: Build a Simple, Clear Plan — and Stick to It
A windfall doesn’t have to be complicated. The goal is to turn a one-time event into long-lasting stability and financial freedom.
At Fortitude Financial Planning, the process typically looks like this:
-
Listen: Understand your goals, emotions, and priorities.
-
Clarify: Map out what this money can help you achieve.
-
Plan: Build a strategy that balances security, flexibility, and long-term growth.
-
Implement: Invest or allocate the funds in a tax-efficient, evidence-based way.
-
Review: Adjust over time as your life changes.
A windfall is an opportunity — but it’s the plan that unlocks its real value.
