A deduction that could help you save as much as $625 on your tax bill.

Repaying student loans isn’t much fun. After completing your college education, you have to erase the resulting debt. And it can take years.

That’s the bad news. But there’s some good news too: Those loans may help you save on your taxes.

That’s right. Come tax season, you may have a few extra dollars in your pocket thanks to the student loan interest deduction. In this quick guide, we’ll run through the basics so that you know what the deduction is, how to calculate it if you’re eligible and how much you might save.

What is the student loan interest deduction?

The student loan interest deduction reduces your taxable income based on how much interest you paid on top of your student loan principal payments.

As an example: If you make $50,000 a year, all of it is subject to taxes. But a $2,000 deduction can bring down your taxable income down to $48,000. That’s the idea behind the student loan interest deduction — to bring down your taxable income.

How student loan interest works

When you need money for education, you might take out a student loan. Lenders won’t give you the money for free. They expect to be paid interest.

You’ll pay this interest as you repay your student loan. In fact, when you make a payment toward your loan, it goes toward the interest first, before any of it reduces your principal (or the original amount you borrowed). Over the course of a year, that interest adds up.

How the tax deduction works

Now comes the student loan interest deduction. To calculate your interest deduction, you take the total you paid in student loan interest for the tax year — from January 1 to December 31, for most people — and deduct it from your taxable income. The deduction is capped at $2,500, and it may be reduced the higher your income is. Federal and private loans both qualify for deducting.

Though it’s a drag you can’t deduct all of your student loan interest, the deduction can be a big help. Ultimately, it lets you pay less in taxes or receive a larger tax refund.

How much could I save?

With a $2,500 deduction cap in 2017, it’s possible to save up to $625 you owe on your taxes — or get an additional $625 on your refund. However, the amount you’ll actually save on your taxes depends on your income and whether you can claim the full $2,500 student loan interest deduction.

Do I qualify for a student loan tax deduction?

Now that you know what the student loan tax deduction is, you may be wondering whether you qualify for it. You’re good to go on the deduction if you meet the following requirements.

1. Your income is under a specific amount, depending on status and income.

Your modified adjusted gross income (MAGI) must be less than $80,000, or $160,000 if you’re married and file jointly. If you make between $65,000 and $80,000, your deduction might be less based on the IRS’s phaseout rules. We’ll cover these in the next section.

What is modified adjusted gross income (MAGI)?

Your MAGI is like your AGI. But it’s “modified” by adding back in special deductions you might’ve taken, like student loan interest, qualified tuition expenses and tuition fees. MAGI is a way of calculating your income to determine whether you’re eligible for such tax benefits as IRA deductions and income tax credits. Of course, it’s also used to determine whether you qualify for the student loan tax deduction.

2. You fall under an accepted filing status.

You don’t qualify if:

  • Someone claims you as a dependent on their tax return.
  • You’re married and file your taxes separately.

3. Your student loan qualifies.

You have a qualified student loan if:

  • You took out the loan solely for higher education expenses.
  • You took out the loan for yourself, your spouse or your dependent.
  • The loan is not from someone related to you or from a qualified employer plan.

4. The student qualifies.

If you took out a parent loan for someone in school, the student must have:

  • Incurred the higher-education expenses around the time you took out the loan.
  • Enrolled in a higher-education program at least half time.

5. Your interest payments qualify.

You must have paid interest on your student loan during the tax year you’re filing for. If you personally didn’t pay interest, you don’t qualify for the deduction.
Furthermore, you must be the one who’s legally obligated to pay interest on the loan. This means the loan must be in your name.

What is Form 1098-E?

If you paid at least $600 in student loan interest to a lender during the year, the lender is required to send you a Form 1098-E. Typically received by January 31st, it shows how much interest you paid to that lender. If you didn’t receive a Form 1098-E, check your account summary or loan statements. Or give your lender a call.

How to calculate my student loan interest tax deduction

If you qualify for the student loan interest deduction, you’re in luck. It’s time to calculate how much you can deduct from your taxes. Keep in mind that if you’re using an online filing service or tax return software, most of these calculations are done for you. You’ll just need to have your numbers handy from the tax forms you received, such as your W-2 and 1098-E.

1. Find your modified adjusted gross income (MAGI).

It takes a few steps to find your MAGI.

  • You’ll first need to go through IRS Form 1040 or Form 1040A and complete the line items in the Income section.
  • Take your result from the Income section to complete the Adjusted Gross Income (AGI) portion.
  • Finally, use your AGI to calculate your modified adjusted gross income.

There’s no section for MAGI on your tax return, but you can calculate it yourself. To calculate your MAGI, you’ll need to add back into your AGI any number of untaxable deductions you might have qualified for. This is the total of lines 48 and 54 on IRS Form 1040. These deductions include student loan interest, qualified tuition expenses and tuition fees, along with rarer deductions like rental losses and adoption expenses.

Why does the IRS use MAGI to determine my eligibility — rather than my AGI?

Your AGI doesn’t necessarily represent what you really earned in a year. That’s because it reflects any of the “adjustments” the IRS allows you to deduct from your income — and, therefore, pay taxes on.

For a more accurate idea of your annual income, the IRS prefers to assess your “modified” AGI — your AGI with all your qualified deductions added back in.

2. Find your filing status.

Choose one of the following as your filing status:

  • Single
  • Qualifying Widow(er)
  • Head of Household
  • Married Filing Jointly

If you need help figuring it out, visit the IRS’s page on determining your status.

3. Know how much student loan interest you can deduct.

Find how much you paid in student loan interest during the year. If your loan servicer sent you a 1098-E, you can easily see how much interest you paid. You can also log on to your loan servicer’s website and view your account summary.
The maximum you can deduct is $2,500.

4. If you make $65,000 or more ($135,000 or more if married and filing jointly), apply the phaseout formula.

You’ll likely to qualify for the student loan interest deduction if you make $65,000 to $80,000 (or $135,000 to $160,000, if you’re married and filing jointly), but your deduction will be reduced according to a phaseout formula.

Here’s how to calculate your deduction under the phaseout formula:

  1. Take your MAGI and subtract $65,000 ($135,000 if you’re married and filing jointly.
  2. Divide that figure by $15,000 ($30,000 if married and filing jointly).
  3. Multiply that resulting figure by your original student loan interest deduction.
  4. Subtract the resulting figure from your original student loan interest deduction.

Does refinancing affect my student loan interest deduction?

It depends. You can most likely deduct student loan interest from your taxes after refinancing.

From time to time, you may find it makes sense to refinance your student loan — for example, to get a better interest rate. However, you may not be able to deduct your student loan interest if you refinance for more than the original amount of your loan.
