How much cash can you legally keep at home under your mattress?

Keeping a stash of notes at home might feel like a throwback to simpler times—but for many, it’s still a tempting way to manage savings. Whether it’s a jar of rainy-day funds or a few wads hidden in a drawer, the appeal of cash-in-hand is clear. But how much is too much before it lands you in hot water?

Is stashing cash at home smart or risky?

We’ve all seen it in films—someone lifting a floorboard to reveal rolls of banknotes hidden away “just in case.” And while it’s not illegal to keep cash at home, there are clear limits if you want to stay on the right side of the law.

Some people find comfort in not relying solely on banks. Whether it’s fear of financial crises, frustration with low interest rates, or just a preference for tangible money, many opt to manage part of their savings the old-fashioned way. And then there’s the simple budgeting appeal: it’s often easier to keep track of your spending when you’re handing over notes instead of tapping a card.

That said, there’s a world of difference between having a few hundred pounds tucked in the kitchen cupboard and stockpiling large amounts in the loft.

The legal limit: how much can you actually keep?

In most European countries—including France—you’re legally allowed to hold onto cash at home, but the moment you exceed €10,000, you’re expected to declare it. That’s per person, not per household. Exceeding this limit without notification could raise eyebrows from the tax office—and potentially lead to serious fines.

Now, you might be thinking: “It’s my money. What’s the harm?” Well, aside from the legal side of things, there are some very practical risks involved. If your home is ever burgled, chances are your home insurance won’t cover the cash. Unlike bank accounts, which in the EU are protected up to €100,000 under the deposit guarantee scheme, your mattress stash is entirely on you.

And if you’re imagining a bank-style heist as the only threat—think again. In 2020 alone, over 490,000 households in France were burgled. That’s nearly half a million potential opportunities for someone to walk away with your life savings in a rucksack.

Why do people still do it?

Despite the risks, cash hoarding is alive and well. A 2016 study by the European Central Bank revealed that 78% of people who keep money at home hold less than €1,000. But overall, the trend is rising. In 2012, French households collectively held around €132.5 billion in cash. By 2020, that figure had soared to €225 billion—roughly €3,360 per person.

There are a few reasons for this uptick. First, cash is seen by some as more “secure” in turbulent times. Others simply don’t trust banks, particularly during financial downturns. And a small group? They’re trying to dodge taxes—though that’s a gamble with high stakes, and tax fraud carries heavy penalties if caught.

Keeping it safe without risking it all

So what if you do want to keep some cash on hand, but not at the expense of your peace of mind? The safest bet, quite literally, is a home safe—one that’s secured to the floor or wall and fireproof, if possible. But even then, insurers may limit the amount they’ll reimburse in case of theft.

If you’re going the DIY route, avoid the obvious hiding spots (behind books, under the mattress, inside cereal boxes). Thieves know all those tricks too. Choose a discreet, hard-to-reach location that doesn’t scream “something valuable is here,” and keep it separate from other high-value items.

Of course, a mixed approach is best. Use banks for most of your funds, and keep only small, manageable amounts of emergency cash at home. That way, you’re covered for unexpected events—without putting your savings, or your sanity, at risk.
