Deductions & credits

Biden’s new student loan repayment will calculate monthly payments based solely off the actual borrower’s income—  even if married,— but ONLY IF they file taxes as MFS. 
I don’t know if that’s the case with the OP here, but filing this way is about to become very very popular with couples who have student loans 

Depending on the income gap, a spouse could save several hundred—if not thousands-- of dollars a month, drastically outweighing any tax benefits they’d  receive filing jointly.
