Massachusetts - Death of Taxpayer/Spouse
1
If a taxpayer or spouse has passed away, you need to enter the date of death of the taxpayer or spouse in the Federal section of the program. See Entering in Program - Name, SSN, and Date of Birth for details. 

This information will then be carried to Massachusetts the return. When you print your Massachusetts return, you will see "EST of ..." in the name section, indicating to the Massachusetts Department of Revenue that a taxpayer has passed away.
