How Does the IRS Find Out About an Inheritance?

A question we hear often from families at Real Time Home Buyers Metro Detroit: "Do I actually have to tell the IRS I inherited something, or will they never know?" Here's how the IRS typically ends up with a paper trail on an inheritance, even though most inheritances aren't taxable.

Probate creates a public record. When an estate goes through probate, court filings — including the will, the executor's appointment, and often an inventory of the estate's assets — become part of the public record. While the IRS doesn't automatically pull every probate file, this paperwork exists and is accessible if the IRS has reason to look.

Large estates file Form 706. If an estate is big enough to exceed the federal estate tax exemption (a very high threshold that only affects a small percentage of estates), the executor must file an estate tax return. That filing gives the IRS a direct record of what assets existed and who received them.

Banks report large cash transactions. If you receive $10,000 or more in cash or cash equivalents (like a cashier's check or money order) as part of an inheritance, the bank is required to report that transaction to the IRS using Form 8300. A regular personal check for the same amount typically doesn't trigger this reporting.

Selling inherited property creates a paper trail of its own. If you inherit a house and later sell it, the closing typically generates a Form 1099-S showing the sale proceeds, which gets reported to the IRS. This is a separate matter from the inheritance itself — it's a record of the sale, not the inheritance.

Income from inherited assets gets reported as it's earned. If you inherit a bank account, stocks, or a rental property, any interest, dividends, or rental income those assets generate after you inherit them shows up on 1099 forms just like any other income-producing asset you own.

Retirement accounts come with mandatory reporting. Inherited IRAs and 401(k)s require distributions on a set schedule, and those distributions are reported to the IRS as ordinary income in the year you take them.

The bottom line: most inheritances themselves aren't taxable and don't need to be reported as income. But a variety of related paperwork — probate filings, large cash transactions, property sales, and income the assets generate — does tend to create records the IRS has access to.
