Most people who inherit money or property owe no federal income tax on the inheritance itself. Cash left to you in a will is not income. A house you inherit is not income. The federal estate tax - which is what most people are thinking of when they worry about "inheritance tax" - is paid by the estate, not by you as a beneficiary, and only applies to estates above $15 million. But there are specific situations where inheriting something does create a tax obligation for you. Knowing which is which saves money and avoids surprises.
Cash you inherit: Not taxable income to you. It was already taxed (or within the estate's exemption). You do not report it as income.
Property you inherit (stocks, real estate, a business): Not taxable when you receive it. But your basis is stepped up to fair market value at date of death - so if you sell it immediately, you owe little or no capital gains tax.
Retirement accounts (IRA, 401k) you inherit: Taxable when you withdraw. The 10-year rule requires full distribution within 10 years of the owner's death.
Income the inherited property generates after you receive it: Taxable to you - rent, dividends, interest all flow to your return going forward.
IRC §102 excludes property received as a gift or bequest from gross income. When someone dies and leaves you $50,000 in their will, that $50,000 is not income on your tax return. You do not report it on Schedule 1. You do not owe income tax on it. The estate may have paid estate tax on it (if the estate was large enough), but that is the estate's liability - not yours.
There is no federal "inheritance tax." Six states have their own inheritance taxes (Iowa, Kentucky, Maryland, Nebraska, New Jersey, Pennsylvania) - these are paid by the beneficiary, not the estate, and depend on your relationship to the deceased and the state's rules. If you inherit from someone in one of these states, check with a local advisor.
When you inherit property - stocks, real estate, a business interest - your basis in that property is stepped up to the fair market value at the date of the decedent's death under IRC §1014. This is one of the most valuable provisions in the tax code. It permanently eliminates all capital gain that accumulated during the original owner's lifetime.
Example: Your parent bought Apple stock in 1995 for $10,000. At death it was worth $500,000. You inherit it. Your basis is $500,000. If you sell it the next day for $500,000, you owe zero capital gains tax. The $490,000 of gain that accumulated over 30 years is permanently gone - not deferred, not passed on, eliminated. This is why "die and hold" is the ultimate buy-and-hold strategy for highly appreciated assets.
Traditional IRAs, 401(k)s, and other pre-tax retirement accounts are the major exception to the "inheritance is not taxable" rule. These accounts were never taxed - the original owner deducted contributions and deferred tax on growth. When you inherit them, you pay ordinary income tax on every dollar you withdraw, just as the original owner would have.
For most non-spouse beneficiaries inheriting from owners who died after 2019, the SECURE Act's 10-year rule applies: the entire account must be distributed within 10 years of the owner's death. If the owner had already started taking required minimum distributions (died after their required beginning date), you must also take annual distributions in years 1-9. See the RMD guide for the full inherited IRA analysis.
Inheriting a share of a partnership, S-corporation, or LLC also receives the §1014 step-up. Your basis equals the FMV of the interest at the date of death. For partnerships with a §754 election in place, the estate's basis adjustment flows through to the partnership's underlying assets, allowing increased depreciation deductions for the beneficiary. For estates inheriting S-corp stock, the S-corp does not get an inside basis adjustment unless it converts to a C-corp (rarely done).
The federal estate tax is imposed on the deceased's estate - not on the beneficiaries. The tax is paid out of estate assets before distribution to heirs. The exemption is $15 million per person (OBBBA permanent, inflation-indexed). For 2026, an individual can die with up to $15 million of assets and owe zero federal estate tax. A married couple using portability has a combined exemption of $30 million. Only the largest estates in the country owe federal estate tax. If you inherit from an estate that does owe estate tax, the reduction in what you receive is the estate's tax bill - it is not a tax assessed on you personally.
