How Inherited Money Is Taxed: Estates, Inheritance, and Stepped-Up Basis

Most Heirs Pay No Federal Tax — But the Details Are Complicated

A parent dies and leaves you $200,000. Do you owe federal income tax on that $200,000? The answer in nearly all cases is no — but that simple answer conceals a web of rules that can cost heirs tens of thousands of dollars if misunderstood. The type of asset inherited (cash, stocks, an IRA, real estate), the size of the estate, and your state of residence all determine what you actually owe. The 2024 federal estate tax exemption is $13.61 million per individual — meaning estates below this threshold pay no federal estate tax at all. But assets like inherited IRAs come with their own mandatory distribution rules that carry substantial income tax consequences.

Federal Estate Tax vs. Inheritance Tax: A Critical Distinction

These two taxes are frequently confused, but they are entirely different mechanisms:

The six states with an inheritance tax are Iowa (phasing out by 2025), Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Whether you owe depends on your relationship to the deceased: spouses are exempt in all six states; children are exempt or lightly taxed in most; more distant relatives and non-relatives face the highest rates, up to 15–18%. Maryland is the only state imposing both an estate tax and an inheritance tax.

The Stepped-Up Basis: The Biggest Tax Benefit Most Heirs Never Claim Correctly

When you inherit appreciated assets — stocks, real estate, a business — the tax law provides a benefit called a stepped-up cost basis. The inherited asset's cost basis is reset to its fair market value on the date of death, erasing any capital gains that accrued during the decedent's lifetime.

Example: Your father bought Apple stock in 2000 for $10,000. It was worth $300,000 when he died in 2024. He would have owed capital gains tax on $290,000 of gains if he had sold it. You inherit it with a basis of $300,000. If you sell it immediately for $300,000, you owe zero capital gains tax. If you sell it a year later for $320,000, you owe capital gains tax only on the $20,000 gain since you inherited it.

This benefit applies to most inherited assets but not to inherited traditional IRAs, 401(k)s, or other pre-tax retirement accounts, which are instead subject to ordinary income tax when distributed.

Inherited IRAs: The 10-Year Rule That Surprises Heirs

The SECURE Act of 2019, followed by SECURE 2.0 in 2022, fundamentally changed how non-spouse beneficiaries must handle inherited IRAs. Under the old rules, beneficiaries could take required minimum distributions (RMDs) over their own lifetime — the "stretch IRA" strategy. Under the new rules:

• Most non-spouse beneficiaries must empty the inherited IRA within 10 years of the owner's death
• If the deceased owner had already begun taking RMDs, beneficiaries must also take annual RMDs during the 10-year period (IRS finalized this interpretation in 2024)
• Spouses, minor children (until they reach the age of majority), disabled individuals, and chronically ill individuals are exempt from the 10-year rule and can still use the stretch

The tax consequence is significant. A $500,000 inherited IRA forced into 10-year distribution could push the beneficiary into a higher tax bracket for each of those years, potentially resulting in a combined federal and state tax rate of 35% or more on the distributions. Timing the withdrawals strategically — taking more in lower-income years, less in high-income years — can meaningfully reduce the total tax bill.

Inherited Retirement Account Types and Their Tax Treatment

Cash, Life Insurance, and Forgiven Debt

Cash inherited directly — whether from a bank account, a sale of estate assets, or a check cut by the estate — is generally not income to the recipient. Life insurance death benefits paid to a named beneficiary are also income-tax-free in virtually all circumstances, regardless of the benefit size. The estate may owe estate tax on the policy's face value if the deceased owned the policy, but the beneficiary owes no income tax on the proceeds received.

One overlooked scenario: inherited property with a mortgage. If the estate's assets include real estate with debt, and you inherit the property, you also inherit the debt. Forgiven debt is normally taxable income — but debt on inherited property that you assume or that is discharged at death follows different rules. Consult a tax professional before making decisions about mortgaged inherited property.

Basis Tracking and the Estate's Obligation

Estates that file an estate tax return (Form 706) are required under IRC Section 1014(f) to report the asset basis assigned to beneficiaries and to provide beneficiaries with a statement. If no estate tax return is filed (because the estate is below the exemption threshold), basis documentation becomes your responsibility as the beneficiary. Retain date-of-death valuations — typically from brokerage statements, appraisals, or the estate's own records — because the IRS can challenge the stepped-up basis claimed years later when you eventually sell.
