What you actually owe when you inherit a home, in plain English

Most families arrive convinced they're about to owe a lot of money to the government. They are usually wrong about which government and which tax. Here is the actual landscape, in the order it tends to matter.

State inheritance and estate tax: usually, but not always, none

Most states take nothing simply because someone died. A minority still levy a state estate tax, an inheritance tax paid by the person receiving, or both — and the rules differ sharply on who is exempt and at what value. Check your own state before you assume either way; in most of the country this is the easiest part of the conversation.

Federal estate tax: probably not yours

The federal estate tax applies only to estates above the federal exemption — currently in the millions per individual, double for married couples. The vast majority of estates don't come close. If your estate does, you already have a planner; if it doesn't, you can stop worrying about this.

Income tax: the deceased's final return

The personal representative files a final Form 1040 covering the part of the year the person was alive. This is not optional and the IRS does notice. If the estate itself takes in income after the death — interest, dividends, rent — it may also need its own return, Form 1041. That one is conditional, not automatic: the threshold is $600 of gross income for the year (or any beneficiary who is a nonresident alien). An estate that holds a house for a few months can cross it without anyone expecting to.

The trap: capital gains and step-up in basis

Here is what families miss, and usually get backwards. When the deceased bought a home in 1972 for $42,000 and it is worth $240,000 at their death, that $198,000 of appreciation would have been a taxable capital gain if they had sold it themselves. They did not — and the tax code forgives it.

Federal law resets the cost basis of inherited property to its value on the date of death. This is automatic. It is not something you elect, plan for, or forfeit by waiting — it happens by operation of law when the person dies. Sell at $240,000 shortly after, and the taxable gain is close to nothing. Transfer the home to a beneficiary instead and their basis is that same date-of-death value, so if they sell five years later for $260,000, what is taxable is the $20,000 of appreciation since the death.

Which is why the familiar advice that "selling right after the death is more tax-efficient" does not really hold. The basis is identical whoever sells. What differs is who reports any gain and at what rate — and there the estate is usually the worse taxpayer, because estates and trusts reach the top long-term capital-gains rate and the 3.8% net investment income tax at only a few thousand dollars of income, where an individual has tens of thousands of headroom. If the sale will produce a real gain, that is a question for a CPA before you decide who sells, not after.

One exception is large enough to be worth knowing about. In community-property states, when one spouse dies, the surviving spouse's half of the community property is stepped up as well — not only the half that belonged to the person who died. That "double step-up" can erase decades of appreciation on a family home in a single event. It is available in a minority of states and turns on how the property was held, so if the couple lived in one of them, raise it specifically with a CPA rather than assuming it applies.

When the home is in a trust

Properly drafted revocable trusts get the same reset: the grantor is treated as the owner, the assets are in their estate, and they take a date-of-death basis. Irrevocable trusts generally do not. Where the grantor genuinely gave the property away during life — nothing retained, nothing pulling it back into the taxable estate — there is nothing to step up, and the beneficiary inherits the grantor's original basis instead. Whether a particular trust is in the first category or the second is one of the few questions where you genuinely need a tax-aware attorney to read the document rather than go by its name.
