Learn how inherited-property basis is determined, when basis can step up or down, which assets are exceptions, and how California rules may apply.
A step-up in basis is an increase in an inherited asset's tax basis to its fair market value at the owner's date of death, or another permitted valuation date. The rule can reduce the capital gain recognized when the heir or estate later sells appreciated property.
"Step-up" is shorthand. If the asset's value at death is below its adjusted basis, the basis can step down. Some inherited items do not receive fair-market-value basis, and a lifetime gift generally follows carryover-basis rules instead.
Basis is used to calculate gain, loss, depreciation, and other tax consequences. The basic sale formula is:
Amount realized − adjusted basis = gain or loss
Daniel dies owning stock with an $80,000 adjusted basis and a date-of-death value of $310,000. If the stock qualifies, the new basis is generally $310,000. The estate later sells it for $322,000 and pays $2,000 in selling costs:
$322,000 − $2,000 − $310,000 = $10,000 gain
Without the basis adjustment, the apparent gain would be much larger. The rule does not create cash or erase post-death appreciation; it resets the starting point for measuring later gain or loss.
The general basis is fair market value at death. If the executor validly elects the federal alternate valuation method on a qualifying Form 706, a different date or distribution-date value can apply. The alternate election is not a beneficiary-by-beneficiary choice made solely to improve income-tax basis.
Fair market value means the price at which willing and informed parties would transact without compulsion. Brokerage statements may support publicly traded securities. Real estate, closely held businesses, collectibles, and fractional interests often need qualified valuation work.
Not every inherited economic benefit receives Section 1014 basis. Important exceptions and special cases include:
A lifetime gift generally carries the donor's adjusted basis to the recipient for gain purposes, with special dual-basis rules when fair market value is lower. An inheritance generally receives date-of-death fair-market-value basis when Section 1014 applies.
Suppose a parent gives stock with a $40,000 basis and $200,000 value during life. The child generally does not receive a $200,000 basis merely because gift tax reporting occurred. If the child instead inherits qualifying stock worth $200,000 at death, basis is generally $200,000.
This distinction is important in estate planning, but tax basis should not be the only consideration. Control, income needs, creditor exposure, property tax, estate-tax inclusion, and family goals require legal and financial advice.
Putting property in a revocable living trust generally does not itself change basis. If the property remains includible in the grantor's estate and is acquired from the decedent under Section 1014, it may receive date-of-death basis when the grantor dies.
An irrevocable trust does not automatically prevent or guarantee a basis adjustment. Estate inclusion, grantor powers, ownership, the trust terms, and the transaction history matter. The title "trust" is not enough to decide the result.
California is a community-property state. When qualified community property is included in a deceased spouse's gross estate, both the decedent's half and the surviving spouse's half may generally receive a fair-market-value basis adjustment under federal law. This is sometimes called a double step-up.
Joint tenancy, tenancy in common, separate property, and community property with right of survivorship can produce different inclusion and basis results. A deed's wording, source of funds, marital agreements, and tracing records can matter. Do not assume every jointly owned California asset receives a 100% adjustment.
Inherited rental or business property may begin a new depreciation schedule based on the portion of inherited basis allocated to depreciable property. Land is not depreciable. A real-estate appraisal should allocate value among land, building, and potentially shorter-lived components when supportable.
Prior depreciation taken by the decedent generally affected the decedent's old adjusted basis, but the heir's depreciation begins from the new inherited basis under applicable recovery periods and conventions. Income in respect of a decedent and entity-owned property can complicate this general explanation.
An inherited asset sale may appear on Form 8949 and Schedule D, Form 4797, Schedule E, or an estate or trust return depending on the asset and owner. Brokers may report basis, but the taxpayer must confirm it. A statement that basis was not reported to the IRS does not mean basis is zero.
California generally excludes the value of an inheritance from income and commonly follows date-of-death basis for inherited property. Federal and California basis can still differ because of historical nonconformity, depreciation, entity rules, or other adjustments. Preserve both schedules when a difference exists.
Retain the death certificate, will and trust, deeds, account statements, appraisals, Form 706 and elections, estate inventory, ownership and community-property records, gift documents, prior depreciation schedules, improvement records, entity agreements, distribution documents, and later sale statements.
Heath Income Tax can reconcile inherited-property basis, sale reporting, rental depreciation, estate or trust returns, and California adjustments using the fiduciary's valuation records.
Do heirs pay income tax when property is inherited?
The inheritance itself is generally not income, but later income and gain can be taxable.
Does basis always increase?
No. It can decrease to fair market value, producing a step-down.
Is an appraisal required?
Not in every case, but the taxpayer needs reliable evidence of fair market value. An appraisal is often prudent for real estate or hard-to-value property.
Does property in a living trust receive a step-up?
Not when it is merely transferred into the trust. A later date-of-death adjustment depends on estate inclusion and inherited-property rules.
