No. The IRS does not treat inherited money, real estate or personal items as income, so a beneficiary in Mississippi does not report them on a federal return when received. Two exceptions: an inherited retirement account (a 401(k) or a traditional IRA) is taxed as ordinary income as it is withdrawn, and earnings after the date of death are taxable. Inherited property takes a stepped-up basis, its value on the date of death, for any later capital gain.

A later sale is taxed on the gain above that stepped-up basis, not above what the original owner paid, so the appreciation of the owner's lifetime is never taxed.
