What to Do With an Inheritance: The First 90 Days

When a significant sum lands, the instinct is to do something: pay off the house, invest it, help family, make the moment count. That instinct is exactly what leads to decisions people later regret. Money that took a lifetime to build does not need to be redeployed in a fortnight.

Here is a calmer way to think about the first three months, in order of what genuinely matters.

Weeks 1–4: Do almost nothing, deliberately

The first job is not financial. It is to give yourself a decision-free buffer so that grief and pressure don't get to make permanent choices on your behalf.

• Park the money somewhere safe and boring. A straightforward, secure account is completely fine as a holding place. Sitting in cash for a few months costs you very little; a rushed decision can cost you a great deal.
• Say "not yet" to everyone. Requests will come: from family, from advisers who heard, from your own guilt. "I'm not making any decisions for a few months" is a complete and reasonable answer.
• Write down what you actually want. Not what the money should do: what you want your life to look like. That, not the balance, is what good decisions get measured against later.

Weeks 4–8: Understand what you've actually received

Inheritances are rarely just cash. The shape of what you've received changes what you can and should do with it.

• Different assets carry different rules. Property, pensions, investment accounts, a stake in a business, and cash are each treated differently: for tax, for access, and for what happens if you hold or sell. Get a clear inventory before you plan anything.
• There may be tax consequences already in motion. Depending on where the estate and where you are based, there can be deadlines and liabilities attached to an inheritance. This is the one area where getting qualified, jurisdiction-specific input early genuinely pays for itself.
• Cross-border adds a layer. If the person who passed, the assets, and you are not all in the same country, the picture gets more complex, and more worth understanding properly before you move money around.

Weeks 8–12: Make only the decisions that are truly time-sensitive

By now the fog lifts a little. Separate the genuinely urgent from the merely loud.

• Clear high-cost, high-stress debt if you have it: this is one of the few moves that is almost always sound and rarely regretted.
• Shore up your own security: an emergency buffer, and a look at whether this changes your own estate planning and who depends on you.
• Everything else can wait. The big questions (how to invest, whether to move, how to help family sustainably) are better answered over the following year, not in the first quarter.

The mistake to avoid

The most common regret isn't a bad investment. It's acting fast to relieve the discomfort of holding a large, unfamiliar sum, and locking in a choice before understanding the full picture. Slowness here is not indecision. It is the strategy.

Frequently asked questions

How quickly do I need to decide what to do with an inheritance?

Rarely as quickly as it feels. Beyond any genuine legal or tax deadlines tied to the estate itself, most choices (how to invest, whether to give, what to spend) can safely wait months. A short, deliberate pause tends to produce better decisions than a fast one made under the weight of grief and pressure.

Is an inheritance taxed?

It depends entirely on where you are based, where the estate sits, and the type of assets involved, so the rules are jurisdiction-dependent rather than universal. Some inheritances carry deadlines or liabilities that are already in motion. Because this is the area where mistakes are costly, it is worth getting qualified, jurisdiction-specific input from a professional early.

Should I use an inheritance to pay off my mortgage or other debt?

Clearing high-cost, high-stress debt is one of the few moves that is almost always sound and rarely regretted. A mortgage is more nuanced (it depends on your wider circumstances and on what you want your life to look like), so it usually belongs among the slower, later decisions rather than the urgent ones. A qualified professional can help you weigh it against your own situation.
