Question

Which of these people should use the "married filing jointly" tax filing stat

Answer 1

You may qualify for more than one tax filing status. For example, a single (unmarried) person isn't necessarily restricted to the single filing status. He or she may be able to file as head of household or qualifying widow(er), assuming those qualifications are met. But if he or she wasn't legally married as of 12/31/2015, they couldn't file their 2015 return as a married person.

Answer 2

A Mr. and Mrs. Jaden, who want to file their income tax return together

Explanation:

Mr Olson is the only earning so he wouldn't need to use a married jointly tax file, while Mr. Alan is also unmarried so he doesn't need one either.
