Two incomes. One household decision.
A smaller loan bill is only one part of the math.
Compare the household total
Ask your tax professional to compare joint versus separate filing using both tax liability and annual loan payments. Include both spouses’ loans, dependents, credits, state rules, and any community-property treatment.
Understand the repayment plan
Under RAP, joint filing generally uses combined income, with an adjustment when a spouse also has federal loans. Separate filing uses the borrower’s income and claimed dependents. Other plans have their own rules.
Bring the right information
Gather tax returns, loan balances and types for both spouses, repayment plans, recertification notices, and employment plans. Do not make a filing decision using a loan calculator alone.
