Estate Tax on Real Estate Passed to Heirs

Passing down real estate raises two separate tax questions that owners often blend together: whether the estate itself owes federal estate tax, and what basis the heirs inherit for capital gains purposes going forward. For a Newport Beach family holding an appreciated rental portfolio or a commercial building acquired decades ago, the second question, the stepped-up basis, usually matters more day to day than the first.

The federal estate tax applies only above a large exemption amount, which sits in the tens of millions of dollars per individual as of the current tax rules and is scheduled to adjust in coming years under recent legislation. Most Newport Beach property owners, even those with substantial real estate holdings, fall well under this threshold and owe no federal estate tax at all. California has no separate state estate tax, so the calculation for most local families comes down almost entirely to the federal exemption and how it is projected to change.

When real estate passes to heirs at death, it generally receives a basis equal to its fair market value on the date of death rather than the original owner's much lower purchase price and depreciated basis. That step-up can erase decades of accumulated capital gains and depreciation recapture that would otherwise have been owed had the owner sold the property during their lifetime. A Newport Beach duplex bought in the 1980s and depreciated for forty years, for example, might pass to heirs at a basis reflecting today's market value, with no capital gains tax due on the appreciation that occurred before death.

This is where the step-up interacts directly with 1031 planning. An owner who deferred gain repeatedly through a series of exchanges over the years, building up a large deferred tax liability in the process, can potentially have that entire liability eliminated at death through the step-up, rather than ever recognizing it. That combination, sometimes summarized as swap until you drop, leads some long-term Newport Beach investors to keep exchanging into larger or better-located replacement property rather than ever selling outright, on the theory that the deferred gain disappears for their heirs rather than becoming due.

California's community property rules add a further wrinkle for married couples. Property held as community property generally receives a full step-up in basis on both halves of the ownership when the first spouse dies, not just the deceased spouse's half, which differs from how basis adjusts for separate or jointly held property in most other states. This distinction can materially change the tax outcome for a surviving spouse who later sells or exchanges a jointly owned Newport Beach property, and it is worth confirming how title is actually held rather than assuming.

None of this replaces coordinated estate and tax planning. Trusts, gifting strategies, and the specific way title is held can all affect whether and how the step-up applies, and estate tax exemption levels are subject to legislative change that could lower the threshold for future years. A family with a significant Orange County real estate portfolio benefits from reviewing the estate plan alongside any active exchange strategy, since a poorly timed sale, an improperly structured trust, or an assumption about exemption levels that no longer holds can each undercut the benefit the step-up is otherwise expected to provide.
