How to Make Roth IRA Contributions When You Have Student Loans

You might have heard that contributing to a Roth IRA is an excellent way to earn tax-free income in retirement. That’s very true, but for student loan borrowers, particularly married ones, it’s much harder to contribute to a Roth IRA directly. 

We’ll show how to easily contribute to a Roth IRA as a student loan borrower, and we’ll explain what to watch out for.

Roth IRA contributions have AGI limits

For 2025, to contribute directly to a Roth IRA, an individual must have a Modified Adjusted Gross Income (MAGI) less than $150,000, or $236,000 if filing jointly.

Many professional degree holders will earn more than that.

If you incorrectly contribute when you’re not eligible, the IRS charges a 6% annual excise tax on the overcontribution until it’s removed.

Now let’s explore why student loan borrowers often have trouble making direct contributions.

Married filing separately Roth AGI limit is incredibly low

For married borrowers filing taxes separately due to their student loans, the income limit to contribute directly to a Roth IRA is only $10,000. 

What often happens is that a married borrower makes a Roth IRA contribution and then files his taxes separately to lower his IDR payment, only to realize that he was not actually eligible to contribute to the Roth IRA in the first place.

That creates a need to recharacterize the Roth contribution as an after-tax Traditional IRA contribution, which is a pain.

Here’s how to correctly contribute to a Roth IRA as a student loan borrower for the first time.

Steps for contributing to a Roth IRA as a student loan borrower 

Here’s a short list of steps to follow to make sure your Roth contribution is allowed:

1. If possible, roll over all pretax IRA accounts to a qualified 401(k) or 403(b) plan to avoid pro-rata taxation. This is helpful to avoid extra work at tax time and to keep things clean.
2. Contribute to a Traditional IRA account and immediately convert the full contribution to a Roth IRA account. Since your funds were in the Traditional IRA account for a short time, you should have earned very little in interest, and there should be almost no tax consequence to this.
3. You’ve now completed the Backdoor Roth IRA contribution! Now, you simply need to invest the money according to your long-term financial goals.

Should you contribute to Roth first or pretax accounts?

Generally, it’s a much better idea to contribute to pretax accounts as a student loan borrower pursuing forgiveness.

That’s because pretax accounts lower your AGI and thus lower your IDR payment. It’s like getting an extra 10% to 15% tax break when you make a pretax contribution. When you’re retired, you will likely be done with student loans, and thus, you won’t need to optimize your tax strategy to reduce your IDR payment. 

If you’ve already maxed out all your pretax accounts, though, it’s a great idea to max out your Backdoor Roth accounts for both you and your spouse if applicable.

This money grows tax-deferred, and the earnings can be withdrawn tax-free after age 59.5.

If you still have more money to invest after maximizing your retirement accounts, your next option is a taxable brokerage account. Brokerage accounts are taxed along the way, and you have to pay capital gains tax when you withdraw the money.

The one big positive to brokerage accounts is that you can withdraw earnings at any time without being subject to penalties. 

Make a Roth IRA a tool instead of a goal unto itself

Roth IRAs are a great tool on the path to financial freedom. However, if you contribute a healthy amount of your income to retirement, you’ll likely be okay with or without them.

For student loan borrowers, you’ll want to focus first on pretax accounts. Then, if you file taxes separately or earn a high income, you’ll need to incorporate Backdoor Roth contributions to avoid the excise tax on overcontributions. 

If you pair your Roth IRA with pretax accounts and a brokerage too, you’ll be well on your path to financial independence, no matter how much student debt you have (because, worst case, that debt is just a really complicated income tax under the IDR plan rules).
