Can I do a backdoor Roth if I file separately?

Direct Roth IRA contributions phase out between $0 and $10,000 of income on a separate return if you lived with your spouse during the year, so most physicians can't contribute directly. You can still make a nondeductible IRA contribution and convert it. If you have other pre-tax IRA balances, the pro-rata rule affects how the conversion is taxed.

Can I deduct my student loan interest?

Up to $2,500 of student loan interest can be deducted above the line while your income is under the phase-out range. It isn't available on a separate return. Many attendings phase out of it, while many residents and fellows still qualify.

Is student loan forgiveness taxable?

Forgiveness under Public Service Loan Forgiveness is not federally taxable. Forgiveness at the end of an income-driven repayment plan is generally taxable federal income; a temporary federal exclusion applied only to discharges through the end of 2025. State treatment varies.

Do you advise on PSLF or repayment plans?

No. We handle the tax side: your return, the tax cost of each filing status, and your overall tax plan. For repayment plans and forgiveness, work with your loan servicer or a student loan specialist.

Student Loans & Taxes

Student Loans.
The Tax Side.

Your student loans touch your taxes in a few specific places: the deductions you can take, how forgiveness is taxed, your filing status, and the income your return reports. Here is what physicians should know.

Quick Answer

Student loans affect your taxes in four places: the student loan interest deduction, the tax treatment of forgiveness, your filing status choice, and the adjusted gross income (AGI) your return reports, which income-driven repayment plans generally use. We handle the tax side. Repayment and forgiveness decisions belong with your loan servicer or a student loan specialist.

Where Loans Meet Your Taxes

The numbers on your return that matter

Your tax return reports your adjusted gross income (AGI). Income-driven repayment plans generally look at that figure, which is why student loans and taxes come up in the same conversation.

On the tax side, pre-tax contributions to a 401(k), 403(b) or HSA lower your AGI and your tax bill. How your repayment plan uses that AGI is a question for your loan servicer or a student loan specialist.

Key Insight

Filing status changes both your tax bill and the AGI each spouse's return reports. Before you choose, it helps to see the tax cost of each option in dollars.

Common Tax Mistakes

Where physicians with loans lose money on taxes

Choosing a filing status without seeing the tax cost of both options
Missing the student loan interest deduction in a year your income qualifies
Overlooking community property rules on separate returns
Being surprised by tax on forgiveness that happens outside PSLF

The Tax Playbook

What we handle on the tax side

Filing Status, Both Ways

We prepare your return as a joint return and as separate returns, so you see the tax difference in dollars before you decide.

Pre-Tax Contributions

Contributions to a 401(k), 403(b) or HSA lower your AGI and your taxes. We build them into your tax plan.

Community Property States

In states like California, Texas and Washington, community income is generally split between spouses on separate returns. We prepare Form 8958 to allocate it correctly.

Roth Savings On A Separate Return

Direct Roth IRA contributions phase out at very low income on a separate return. A backdoor Roth is still allowed, and we watch the pro-rata rule.

Tax On Forgiveness

Forgiveness under PSLF isn't federally taxable. Forgiveness at the end of an income-driven plan generally is, now that the temporary exclusion has ended. If a taxable discharge is coming, we plan for the tax.

Student Loan Interest Deduction

Up to $2,500 above the line while your income is under the phase-out. It isn't available on a separate return. Most attendings lose it; many residents and fellows still qualify.

Filing Separately: The Tax Trade-Offs

What changes on a separate return

Married filing separately is usually the more expensive way to file. The brackets are narrower, and several benefits are lost or limited.

Couples with student loans still ask about it because a separate return reports only one spouse's income. Whether that matters for your loans is a question for your loan servicer or a student loan specialist. Our job is to show you what filing separately costs in tax.

On A Separate Return

Narrower tax brackets, so the same income can reach higher rates sooner
No student loan interest deduction
No education credits
Direct Roth IRA contributions phase out at very low income
If one spouse itemizes, the other must itemize too
Community property states split certain income between spouses

Student Loan Tax FAQ

No. Filing separately often raises a married couple's combined tax: the brackets are narrower, and several benefits, including the student loan interest deduction and the education credits, are lost or limited. We prepare the return both ways so you can see the actual tax difference.
