Final answer:
The most favorable method for Allison to report the final payment for contract work done by her deceased husband Alan is to include it on the couple's jointly filed 2021 tax return.
Step-by-step explanation:
The correct option : c
This is premised on the idea that income earned by a deceased person prior to their death should be included on the final joint return with the surviving spouse for the year in which the deceased person passed away. In this case, since Alan performed the work in 2021 and passed away the same year, his income should be reported on the joint return for that year. This is since income is typically reported in the year it is earned, not when it is paid.
Option A is incorrect because the income was earned in 2021 and thus should be reported in that tax year. Option B is typically reserved for income earned by the estate after the date of death, and this income was earned by Alan before his death. Lastly, option D is incorrect as filing a separate tax return for Alan would not be the most favorable, given that joint filing often provides better tax benefits.
