No. The IRS does not treat inherited money, real estate or personal items as income, so a beneficiary in Arizona 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 Two exceptions: an inherited retirement account (a 401(k) or a traditional IRA) is taxed as ordinary income as it is withdrawn, and earnings after the date of death are taxable.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.
