Found Money on the Ground: Can You Keep It?

Found money on the ground is not automatically yours to keep — in most states, whether you can legally keep it depends on how much it is, where you found it, and whether you made a reasonable effort to find the owner first. A $5 bill blowing across an empty parking lot is one situation. An envelope with $900 in it on a store floor is a very different one.

Here is the short version. Nearly every state treats lost property as still belonging to its owner. Many states require you to turn cash over to police above a dollar threshold, hold it for a set waiting period, and only then transfer ownership to you if nobody claims it. The thresholds and waiting periods vary a lot by state, so the number that applies to you is the one in your own state’s statute.

And separately from all of that: if you do end up keeping it, the IRS treats found property as taxable income. That surprises almost everyone. Below is what actually happens, step by step, and how to check the rule where you live.

What the law says about found money on the ground

Most states have two overlapping rules. The first is a “lost and found” statute telling you what to do with property you find. The second is a criminal statute — usually called theft of lost or mislaid property — that applies when someone knowingly keeps property they know is lost and makes no reasonable attempt to return it.

Oregon’s version, ORS 164.065, is typical: a person commits theft if they come into control of property they know or have good reason to know is lost or mislaid and, intending to deprive the owner, fail to take reasonable measures to restore it. Pennsylvania, Illinois, and Georgia have similar “reasonable measures” language.

Notice what that standard does. It does not demand that you succeed in finding the owner. It asks whether you tried. A quick call to the property owner, the store manager, or the local police department is usually what “reasonable measures” looks like in practice — but courts decide it case by case, and no statute gives you a checklist.

Lost, mislaid, or abandoned: the distinction that decides everything

Lawyers split found property into categories, and they lead to different outcomes.

• Lost — the owner parted with it accidentally and doesn’t know where it is. A bill that fell out of a pocket on the sidewalk.
• Mislaid — the owner set it down deliberately and forgot it. A wallet on a restaurant counter. In many states, mislaid property goes to the owner of the premises to hold, not to the finder.
• Abandoned — the owner gave up all claim to it. Cash is rarely treated as abandoned, because people don’t abandon money.

This is why the same $200 leads to different answers depending on the setting. Found money on the ground in a public park has no obvious premises owner. The same amount on the floor of a grocery store often does, and many state and local rules point you to the store first.

What to do step by step when you find cash

1. Don’t spend it. Spending money you know is lost is the fact pattern the theft statutes describe.
2. Look around. If it’s inside a business, tell the manager. If it’s a parking lot, the lot has an owner.
3. Note the details. Date, exact spot, amount. Several states require a sworn statement with that information when you turn property in.
4. Call the non-emergency police line. Ask what the threshold and procedure are in your city.
5. Ask in writing to claim it later. Some states only return unclaimed property to the finder if the finder asked for it up front.
6. Keep your receipt. It’s your proof of the date the waiting period started.

That last step matters more than people expect. If your claim depends on a 90-day clock, you want documentation of when the clock began.

How long before found money on the ground becomes legally yours

Waiting periods and dollar thresholds are set state by state, and sometimes by city ordinance on top of that. Here are three real, verifiable examples — treat them as illustrations of how much the rules differ, not as the rule where you live.

Under California Civil Code § 2080.1, the finder turns the property over to the police department where it was found — or the county sheriff if it was found outside city limits — with an affidavit stating when and where. Your state may use different numbers entirely. Search your state’s code for “lost property” or call your local police records division and ask.

Does the IRS tax found money on the ground?

Yes. IRS Publication 525 states that if you find and keep property that doesn’t belong to you that has been lost or abandoned — sometimes called treasure trove — it’s taxable to you at fair market value in the first year you establish undisputed ownership.

The legal backbone is Internal Revenue Code Section 61, which defines gross income as all income from whatever source derived unless a specific provision excludes it. The IRS position was tested in court in Cesarini v. United States in 1969, involving cash found inside a used piano. The finders were taxed on it.

The practical takeaway: the taxable year is generally the year ownership becomes undisputed — which, if there’s a 90-day police hold, may not be the year you picked it up. A tax professional or IRS.gov can tell you how that applies to your situation. This article describes how the rule works; it isn’t tax advice.

If you receive benefits, reporting requirements generally apply

If you get SSI, SNAP, Medicaid, Section 8, or similar assistance, keeping found money on the ground can interact with your case, and reporting requirements generally apply. Whether anything actually changes depends on the program, the amount, and your household — nobody can tell you the outcome from a web page.

For SSI, SSA guidance says to report changes no later than 10 days after the end of the month in which the change occurred, and notes a penalty of $25 to $100 per unreported or late-reported change. SSA also sets the countable resource limit at $2,000 for an individual and $3,000 for a couple.

For SNAP, 7 CFR 273.9 treats nonrecurring lump-sum payments as resources in the month received under § 273.8(c) rather than as income. Medicaid, Section 8, and state programs each have their own rules, and many are administered at the state level.

Call your caseworker or the agency directly — SSA at 1-800-772-1213, or your state SNAP and housing offices. Report it, ask what it means for you, and get the answer from the agency that runs your case.

What most people get wrong about found money on the ground

“Finders keepers is a law.” It isn’t. It’s a playground saying. The actual legal question is whether you took reasonable measures to restore the property.

“Cash is untraceable, so it doesn’t count.” Traceability and legality are separate questions. The theft-of-lost-property statutes turn on what you knew and what you did, not on whether anyone can prove it later.

“Small amounts have no rules.” Many states do set a floor — New York’s is $20, California’s is $100 — but “below the threshold” only means you’re not required to turn it in to police. It doesn’t erase the general duty to try to return property you know is lost.

“If I turn it in, I lose it.” Often the opposite. Turning it in is frequently the only path that ends with clear legal title in your name.

“Found money on the ground isn’t income.” Publication 525 says otherwise.

Frequently Asked Questions

Can I keep a $5 bill I find on the sidewalk?

Practically, small amounts with no way to identify an owner almost never generate a police report or a prosecution, and most states’ turn-in thresholds sit above that amount. The general duty to make a reasonable effort still exists. Check your own state’s lost-property statute for its threshold.

What if I find money inside a store?

Tell the manager. Money left on a counter or a store floor is often treated as mislaid rather than lost, and in many states the premises owner holds mislaid property so the true owner can come back for it. Ask the store to log it.

Do I owe tax if the owner claims it back?

If the owner claims it, you never established undisputed ownership, so there’s nothing to report. Publication 525 ties the taxable event to the first year you establish ownership of found property. Ask a tax professional about your specific facts.

How do I find my state’s rule?

Search your state legislature’s website for “lost property” or “lost and found” in the civil code, and check your city’s municipal code too. Then call the non-emergency police line and ask about their local procedure and holding period. Don’t rely on a figure quoted for another state.
