1099 misc

Yes, this is taxable income. The 1099-MISC is income paid in respect to the decedent. Since this was reported on a 1099-MISC, as it should have been according to the IRS Pub 559 (p. 14-15), this is added as other income on your tax return.

Wages. The entire amount of wages or other employee compensation earned by the decedent but unpaid at the time of death is income in respect of a decedent. The income isn't reduced by any amounts withheld by the employer. If the income is $600 or more, the employer should report it in box 3 of Form 1099-MISC, Miscellaneous Income, and give the recipient a copy of the form or a similar statement. Wages paid as income in respect of a decedent aren't subject to federal income tax withholding.
