Father died 4/15/17 and Mother just passed 8/10/17. Can I file joint return for both as 'deceased filing jointly' for 2017?

[SweetieJean · Accepted solution]

In the case of death of one spouse or both spouses, the joint return with respect to the decedent(s) may be made only by the executor or administrator.
