Filing Taxes Separately? Here’s Why the March 31 Student Loan Deadline Matters
For many married borrowers with federal student loans, filing taxes Married Filing Separately has long been a strategic way to reduce monthly payments under income-driven repayment (IDR) plans.
By filing separately, borrowers can often keep their student loan payments based only on their own income, instead of their spouse’s combined earnings. For households where one spouse earns significantly more than the other, this approach can lower monthly payments substantially.
But major student loan repayment changes in 2026 could make this strategy less effective.
A new income-driven plan called the Repayment Assistance Plan (RAP) will replace several existing plans for new loans and for borrowers who consolidate after certain deadlines. Because RAP calculates payments differently than today’s IDR plans, many borrowers who currently benefit from filing taxes separately may see higher student loan payments in the future.
Understanding these changes now can help you plan ahead, especially with a March 31, 2026 consolidation deadline that may protect access to current repayment plans.
How Current IDR Plans Treat Married Borrowers
Several existing income-driven repayment plans allow borrowers to exclude a spouse’s income when calculating student loan payments if they file taxes separately.
Plans that currently allow this include:
- Pay As You Earn (PAYE)
- Income-Based Repayment (IBR)
- Income-Contingent Repayment (ICR)
Under these plans, borrowers typically report:
- Their adjusted gross income (AGI) from their tax return
- Their family size, which can include dependents living in the household even if the borrower does not claim those dependents on their taxes
This flexibility can significantly lower monthly payments, particularly for households where:
- One spouse has most of the income
- The student loan borrower earns less
- Children are claimed on the other spouse’s tax return
According to the U.S. Department of Education, income-driven repayment plans calculate monthly payments based on income and family size to make federal student loans more affordable. (see https://studentaid.gov/manage-loans/repayment/plans/income-driven)
For many families, the ability to file taxes separately and still count household dependents has been a key way to reduce payments while working toward loan forgiveness.
How the New RAP Plan Changes the Rules
Beginning July 1, 2026, the new Repayment Assistance Plan (RAP) will become the primary income-driven repayment option for many borrowers.
RAP introduces two major changes that may affect borrowers who file taxes Married Filing Separately.
1. Dependents Must Be Claimed on Your Tax Return
Under RAP, borrowers filing separately generally can only include dependents in their family size if they claim those dependents on their tax return.
This means borrowers who currently include children in their household size may no longer be able to count them when calculating payments, if the other spouse claims them on taxes.
For families using tax filing strategies to minimize student loan payments, this rule change can increase monthly payments significantly if moving to RAP.
2. No More $0 Payments
Another important change is RAP’s minimum monthly payment requirement.
Under existing IDR plans, borrowers with low income relative to their family size can qualify for $0 monthly payments, which still count toward forgiveness under programs like Public Service Loan Forgiveness (PSLF) or IDR Forgiveness.
RAP introduces a $10 minimum payment, meaning borrowers will always have at least a small monthly payment, even when income is very low.
Why the March 31 Consolidation Deadline Matters
Most borrowers do not need to consolidate their federal loans in order to access income-driven repayment plans. However, there are situations where consolidation may be necessary or beneficial.
For example, borrowers may consider consolidation if they have:
- FFEL or Perkins loans but want to pursue Public Service Loan Forgiveness (PSLF)
- Multiple loans with different PSLF qualifying payment counts and want to simplify repayment timelines (explained in more detail in our guide here:

In these situations, the March 31, 2026 consolidation deadline becomes important.
Borrowers who consolidate before that deadline may retain access to current IDR plans such as PAYE, IBR, or ICR. These plans often provide more flexibility for borrowers filing taxes separately.
Borrowers who consolidate after the deadline will typically only have access to the new RAP repayment plan, which uses different family-size rules and may increase payments for some households. Additionally, for borrowers pursuing IDR Forgiveness, RAP requires 30 years in repayment, compared to the 20-25 years required under current IDR plans.
However, consolidation should always be evaluated carefully.
Borrowers pursuing IDR Forgiveness should know that under current Department of Education rules, consolidating will reset the qualifying payment count toward IDR forgiveness. For many borrowers close to forgiveness, consolidation may not be the right strategy.
What Borrowers Should Do Now
If you are married and currently using an income-driven repayment plan, it may be worth reviewing your strategy before the new rules take effect.
Consider taking these steps:
- Review your current repayment plan
Understand whether you are enrolled in PAYE, IBR, or ICR and how your payments are calculated. - Evaluate your tax filing strategy
If you file Married Filing Separately to lower payments, the RAP changes may affect your future payment amounts. - Consider consolidation timing carefully
Consolidating before the March 31 deadline may preserve access to legacy IDR plans with more flexible rules.
Understanding how these rules affect your household can make a meaningful difference in how much you pay over time and how quickly you reach student loan forgiveness.
