If a 1099 arrived after someone left you money or property, it’s almost never taxing the inheritance itself. Federal law excludes gifts, bequests, and inheritances from your gross income.1eCFR. 26 CFR 1.102-1 – Gifts and Inheritances The reason you received a 1099 for an inheritance is that something inside the inheritance either earned income, was distributed from a retirement account, or was sold. The letter and number on the form tell you which.
Here’s how to read the form you got and figure out what, if anything, you actually owe.
The Inheritance Is Tax-Free; The Income It Produces Is Not
The rule draws a sharp line. The property that passed to you at death is excluded from your income. Anything that property earns after the date of death is ordinary taxable income, treated no differently than income from any other asset you own. A $300,000 brokerage account left by a parent costs you nothing in federal income tax at the moment of inheritance. The dividends and interest that account throws off from the day your parent died forward are yours, and whoever holds the money will report them to the IRS.
Life insurance follows the same pattern. The death benefit itself is generally not includable in gross income, but if the insurer holds the proceeds and pays you interest before you withdraw, that interest is taxable and shows up on a 1099-INT.2Internal Revenue Service. Life Insurance and Disability Insurance Proceeds
With that framing in mind, look at which 1099 you received.
1099-R: You Took Money From an Inherited Retirement Account
This is the most common reason a 1099 arrives after a death. Any distribution from an inherited IRA, 401(k), or similar plan is reported by the custodian on Form 1099-R.3Internal Revenue Service. About Form 1099-R, Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, etc. You report that distribution on your own return the same way the original account holder would have.4Internal Revenue Service. Retirement Topics – Beneficiary
The reason traditional retirement accounts are fully taxable when inherited is that the money in them has never been taxed. The original owner took a deduction going in and the account grew tax-deferred. That deferred bill now belongs to you.
Inherited Roth IRAs are the exception. Withdrawals of contributions are tax-free, and earnings are tax-free too in most cases; earnings become taxable only if the Roth was less than five years old when the withdrawal happens.4Internal Revenue Service. Retirement Topics – Beneficiary You’ll still get a 1099-R, but the taxable amount in Box 2a will often be zero.
One planning point worth knowing before you make withdrawal decisions: for most non-spouse beneficiaries of account holders who died in 2020 or later, the account must be fully distributed within 10 years of the death. Compressing withdrawals into that window can push you into higher brackets, so the timing of when you pull money out matters more than it used to.
1099-INT and 1099-DIV: Interest and Dividends on Inherited Accounts
Bank accounts pay interest. Stock and fund holdings pay dividends. Once inherited assets are retitled into your name, the bank or brokerage reports the income directly to you on a 1099-INT or 1099-DIV. This is post-death income on assets you now own, and it’s taxable just like interest and dividends on anything else you hold.
If the assets haven’t yet been retitled and are still sitting inside the estate during administration, the financial institution reports the income to the estate instead. Your share then flows to you through a Schedule K-1, not a 1099. That form is a common source of confusion.
Schedule K-1: The Form People Mistake for a 1099
If the estate itself earned income and distributed some to you, the executor sends a Schedule K-1 (Form 1041) rather than a 1099.5Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 The K-1 breaks your share of estate income into categories: interest in Box 1, business income in Box 6, rental income in Box 7, and so on.6Internal Revenue Service. Instructions for Schedule K-1 (Form 1041) for a Beneficiary Filing Form 1040 or 1040-SR
Both a K-1 and a 1099 report taxable income you must include on your personal return. The difference is who is reporting: 1099s come from financial institutions, plan custodians, and closing agents; K-1s come from the estate. If the estate takes a long time to settle, you can receive K-1s for multiple years as the assets keep earning. The executor is required to provide the K-1 by the estate’s return deadline, which for a calendar-year estate is April 15 of the following year.7Internal Revenue Service. 2025 Instructions for Form 1041 and Schedules A, B, G, J, and K-1
1099-S: Inherited Real Estate Was Sold
When an inherited home or other real property is sold, the closing agent files Form 1099-S reporting the gross proceeds.8Internal Revenue Service. Instructions for Form 1099-S, Proceeds From Real Estate Transactions Seeing the full sale price on a tax form is alarming, but it isn’t what you’ll be taxed on.
Inherited property receives a stepped-up basis equal to its fair market value on the date the owner died.9Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent Your taxable gain is the sale price minus that stepped-up basis, not the original purchase price the decedent paid. A house a parent bought in 1985 for $80,000, worth $350,000 on the date of death and sold by you for $360,000, produces a $10,000 gain, not $280,000. Missing the stepped-up basis and reporting the decedent’s original cost is one of the most expensive filing mistakes a beneficiary can make.
Keep the documentation for the date-of-death value. If you report a basis higher than the property’s final value for federal estate tax purposes, the IRS can apply an accuracy-related penalty on any resulting underpayment.10Internal Revenue Service. Gifts and Inheritances
There is a narrow exception to the 1099-S filing requirement for a seller’s principal residence at $250,000 or less ($500,000 for married sellers) with a certification that the full gain is excludable.8Internal Revenue Service. Instructions for Form 1099-S, Proceeds From Real Estate Transactions It rarely helps with an inherited property, because the home was typically the decedent’s residence rather than yours.
What Happens If You Don’t Report It
The IRS receives copies of every 1099 and K-1 issued in your name and runs automated matching against your return. A mismatch usually produces a notice and a bill for the tax, plus interest.
On top of that, the IRS can impose an accuracy-related penalty of 20% of the underpayment when it stems from negligence or disregard of the rules.11Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments If the IRS finds the omission was fraudulent, the penalty on the fraud portion is 75%.12Office of the Law Revision Counsel. 26 USC 6663 – Imposition of Fraud Penalty The safer path is to include every reported amount and, where appropriate (a stepped-up basis on a 1099-S, a nontaxable Roth distribution on a 1099-R), show the correct taxable figure with the numbers to back it up.
One Note If the Inheritance Came From Abroad
An inheritance from a foreign estate or nonresident alien is still not taxable income, but if the total foreign gifts and bequests you received during the year reach $100,000 in aggregate, you must file Form 3520 as an information return. No tax is due on the inheritance itself. But the penalty for not filing when required is 5% of the unreported amount for each month the failure continues, up to 25%.13Internal Revenue Service. Instructions for Form 3520 A foreign inheritance doesn’t produce a 1099, so it’s easy to assume no reporting is required. Check the threshold before you assume that.
