“Married Filing Separately”: Student Loan Payment Impacts

Each tax season, married couples have a choice to make: Should they choose to file a joint return or file their taxes separately?

The overwhelming majority end up opting for “married filing jointly” status, and often that makes sense. But if you or your spouse are repaying federal student loans on an income-driven repayment plan, you may want to run the numbers to see if filing separately could potentially lower your monthly loan payments.

Read on for a look at the pros and cons of married filing separately with student loan payments and to find out if it could work for you.

Key Points

•   Filing taxes separately as a married couple can result in lower student loan payments under income-driven repayment (IDR) plans.

•   By filing separately, a borrower’s monthly payment under an IDR plan is based on their own discretionary income. When filing jointly, payments are based on both spouses’ income.

•   However, filing separately as a couple may lead to loss of tax benefits such as certain credits and deductions, including the student loan interest deduction.

•   Doing the math, using the Federal Student Aid’s Loan Simulator, or consulting with a tax professional could help you determine what tax filing status is best.

•   Other options for lowering student loan payments include Graduated or Extended Repayment Plans and student loan refinancing.

Married Filing Taxes Jointly vs. Separately

When you’re married, choosing to file your taxes jointly vs. separately can make a significant difference in the size of your refund or what you owe. Most married couples decide to file a joint return for the tax advantages the IRS offers to those who select this status. But there are times when filing separately may be the better choice for your family’s financial needs.

If you took out federal student loans for help with paying for college tuition, and your student loan repayment plan is determined by the income you report on your tax return each year, for example, you might be able to lower your monthly loan payments by filing separately.

That’s because with an income-driven repayment (IDR) plan like Income-Based Repayment (IBR), Pay As You Earn Repayment (PAYE), or Saving on a Valuable Education (SAVE), your discretionary income is used to calculate your monthly payment amount.

If you file a joint return with your spouse, your payments are based on your joint discretionary income. But if you file separately, your payments will be based only on your individual discretionary income — which could mean a lower student loan payment.

You might have heard recently about the SAVE plan and married filing separately. However, the SAVE plan has been blocked by court actions and is on hold. Borrowers can still apply for the plan if they choose; those who are already on the plan have been placed in forbearance until further notice, with no monthly payments due and no interest accruing.

If you have private student loans, these loans don’t have the same repayment options that federal student loans do. That means your tax filing status won’t impact your monthly private student loan payments.

Spouses No Longer Need to Cosign IDR Applications

One change that will affect married borrowers is that spousal signatures are no longer required for most IDR applications, whether the couple files their taxes jointly or separately. This includes the SAVE plan for married filing jointly couples. (The only exception is when a couple is paying their student loans together using an Income-Contingent Repayment (ICR) plan.)

In the past, a spouse had to sign to verify that all information on the form, including family size and income, was accurate. Removing the requirement should make it simpler for a married borrower to file his or her application.

Tax Differences Between Filing Separately vs. Jointly

If you and your spouse are thinking about filing your taxes separately in an effort to lower student loan payments on an IDR plan, it’s important to calculate what you could save on your monthly loan bill and then compare that amount to what you might lose in tax benefits for the year.

The tax consequences of filing separately vs. jointly can vary significantly depending on each couple’s unique circumstances, and they can change from year to year. But you could lose quite a few tax advantages by choosing the “married filing separately” designation.

Filing separately can limit the availability of certain tax credits and deductions, such as the American Opportunity Tax Credit (for educational expenses), the Earned Income Tax Credit, the Child Tax Credit, and the Child and Dependent Care Credit. Nor will you be able to claim the student loan interest deduction, which allows you to deduct up to $2,500 in interest paid on your federal and private student loans.

Filing separately may also affect your tax rates and the amount of your standard deduction. And it can restrict a married couple’s ability to offset capital gains with capital losses (a process known as tax-loss harvesting).

Another important factor to consider is that if you choose to file separately, you and your spouse must agree on whether you’ll claim the standard deduction or itemize your deductions. Both spouses must use the same method on their separate returns.

IDR Plans: Low Payments When Filing Separately

Good communication can be key for couples making decisions about how to file, how they will split their finances and manage their deductions if they file separately and other tax questions.

You may want to sit down with a tax professional who can help you run the numbers and assess how all your filing choices could impact your current and future tax bills. And you can use the Loan Simulator on the Federal Student Aid website to get help estimating loan payments based on various IDR plans as well as factors like income, family size, and tax filing status.

When might it make sense to file separately? Let’s say one spouse earns $200,000 a year and has no student loan debt, and the other spouse earns $50,000 a year and has $150,000 in student debt. Instead of using their joint discretionary income when applying for PAYE — which is open only to those on the blocked SAVE plan who want to switch over, as well as new borrowers as of October 1, 2007 who received at least one Direct loan after October 1, 2011 — the couple could file their taxes separately so that the spouse with the lower income and student loan debt could qualify for a lower monthly payment.

As mentioned above, PAYE isn’t the only IDR plan that allows couples to potentially lower their student loan payments by filing their taxes separately. The IBR and SAVE options also allow couples to separate their finances in an effort to minimize their monthly payments and/or reach forgiveness sooner. But each program has different rules regarding monthly payment caps, how long it can take to get student loan forgiveness, and more. So it makes sense to check out the pros and cons of each to find the plan that’s the best fit for your family’s needs.

Other Repayment Options

As you’re doing your research, you may also want to look into other strategies that could help reduce your payments.

One option is a Graduated Repayment Plan, which can keep your payment timeline to 10 years (or up to 30 years if you’ve consolidated your loans). Under this plan, you start out with lower payments and then the payment amount slowly increases over time based on your expected income.

If you owe more than $30,000 in federal student loans, you may be eligible for the Extended Repayment Plan, which extends your loan repayment timeline to 25 years. If you extend your loan term, you’ll end up paying more interest, but your monthly payments will be reduced.

Refinancing your student loans could be another way to get a lower interest rate or longer loan term, or both, which could help lower your monthly payments. When you refinance, you replace your current loans with a new loan from a private lender like a bank, credit union, or online lender. However, if you refinance federal student loans, you’ll lose access to important benefits, like IDR plans, so make sure you won’t need these programs before moving ahead.

The Takeaway

If you and your spouse are struggling to repay your federal student loans — or if you want to lower your payments to make room for other goals — you may want to look into switching to an income-driven repayment plan. With these plans, couples have the option of choosing the “married filing separately” designation when filing their taxes, which means their student loan payment amount can be based on just the borrowing spouse’s discretionary income instead of the couple’s combined discretionary income.

Couples who file separately may lose several tax breaks, however, which could mean a higher tax bill. So it’s important to calculate what you could save on your monthly student loan bill and then compare that amount to what you might lose in tax benefits for the year.

Looking to lower your monthly student loan payment? Refinancing may be one way to do it — by extending your loan term, getting a lower interest rate than what you currently have, or both. (Please note that refinancing federal loans makes them ineligible for federal forgiveness and protections. Also, lengthening your loan term may mean paying more in interest over the life of the loan.) SoFi student loan refinancing offers flexible terms that fit your budget.
