Death and Capital Gains Taxes (United States)
Stocks (among other property) currently is allowed a "stepped-up basis" when valuing for estate tax purpose.  From the US IRS web page: To determine if the sale of inherited property is taxable, you must first determine your basis in the property. The basis of property inherited from a decedent is generally one of the following: The fair market value (FMV) of the property on the date of the decedent's death. The FMV of the property on the alternate valuation date if the executor of the estate chooses to use alternate valuation. See the Instructions for Form 706, United States Estate (and Generation-Skipping Transfer) Tax Return. If you or your spouse gave the property to the decedent within one year before the decedent's death, see Publication 551, Basis of Assets. Your question continues "the person that died still has to pay taxes on their profits in the year they died, right?" Yes. The estate would be subject to tax on realized gains/losses prior to death.
