When someone inherits stocks or other investments, the value of the account is only one part of the financial picture. The tax basis assigned to inherited assets can influence how much capital gain may be recognized if the beneficiary later sells them.
For many inherited assets, federal tax rules generally use the property's fair market value at the date of the original owner's death. This is often described as a stepped-up basis, although the actual rules include exceptions.
What is cost basis?
Cost basis is generally the amount used to calculate taxable gain or loss when an investment is sold. For a typical stock purchase, it usually starts with the purchase price and may be adjusted for certain events.
If an investor buys shares for $5,000 and later sells them for $8,000, the basic capital gain is $3,000, before considering fees or other adjustments.
Inherited investments may receive a different basis treatment from assets purchased directly by the beneficiary.
How inherited basis generally works
For many inherited assets, the basis is generally the fair market value on the date of the previous owner's death. An executor may sometimes elect an alternate valuation date when the estate tax rules permit it.
For example, if a person purchased shares years earlier for $10,000 and they were worth $30,000 when the owner died, the beneficiary's basis may generally be $30,000. If the beneficiary later sells them for $32,000, the taxable gain may be much smaller than it would have been using the original $10,000 cost.
This is a simplified illustration. The correct valuation and tax result depend on the asset, estate circumstances, and applicable rules.
Important exceptions and complications
Not every inherited asset receives the same treatment. Certain property transferred shortly before death, community-property situations, retirement accounts, and other special circumstances can involve different rules.
Inherited traditional IRAs, for example, are not treated like inherited taxable brokerage shares. Beneficiaries generally need to follow retirement-account distribution rules rather than simply applying a new stock cost basis.
The date-of-death value may also need documentation. Executors and beneficiaries should retain brokerage statements, valuation records, estate documents, and transaction histories.
Before selling inherited investments
Beneficiaries should contact the brokerage firm to confirm that the account has been correctly retitled and that the cost-basis records reflect the inheritance. They should avoid assuming that a broker's displayed basis is complete or correct without reviewing supporting documents.
An estate attorney or tax professional can help determine whether an exception applies and how a sale should be reported.
Bottom line
Inherited investments may receive a new tax basis, which can significantly affect taxable gains when assets are sold. Accurate valuations and records are essential. Beneficiaries should confirm the basis before making major investment or tax decisions.
