We don’t have the nitty gritty details, but if this mom is married and is living with her spouse, she has two choices of how to file taxes…married filing separately and married filing jointly.
@BelknapPoint is there any provision for HOH for a married couple who are living together?
The OP needs to be certain that this is an accurate tax filing. If the FAFSA indicates “married” as the status, and the tax filing is HOH, this will very very likely trigger verification…and the family will need to provide documentation that proves that HOH is a viable filing status. And if it’s NOT, the family will need to reconcile their tax return with the marital status…or no aid will be given.
