Backdoor Roth IRA for Physicians: Step-by-Step for 2026
Key takeaways
- Physicians above the 2026 Roth IRA income limits ($168,000 single, $252,000 joint) can still fund a Roth IRA through a nondeductible contribution and conversion.
- The pro-rata rule taxes part of the conversion if you hold pre-tax IRA balances, so roll those into an employer plan first if possible.
- Each spouse can do a backdoor Roth, so a married couple can move $15,000 a year in 2026 (more with catch-up).
- File Form 8606 every year you contribute or convert.
Why physicians use the backdoor
Direct Roth IRA contributions phase out between $153,000 and $168,000 of modified AGI for single filers and $242,000 and $252,000 for married couples in 2026. There is no income limit on contributing to a nondeductible traditional IRA or on converting to Roth, so the two steps together give high earners Roth access.
Step by step
- Confirm you have no pre-tax balances in traditional, SEP or SIMPLE IRAs on December 31 of the conversion year (or roll them into an employer 401(k) or 403(b) that accepts rollovers).
- Contribute $7,500 (or $8,600 if 50 or older) to a traditional IRA as a nondeductible contribution.
- Convert the balance to your Roth IRA. Waiting a short time is common practice, but the conversion itself is allowed immediately.
- Report the nondeductible contribution and the conversion on Form 8606.
- Repeat for your spouse with their own IRA.
The pro-rata rule
When you convert, the IRS treats all of your traditional, SEP and SIMPLE IRAs as one account. If you have $92,500 of pre-tax IRA money and add $7,500 of nondeductible money, 92.5% of any conversion is taxable. Rolling pre-tax IRA money into an employer plan before year-end avoids this. Solo 401(k) plans for 1099 physicians often accept these rollovers.
The mega backdoor Roth
Some 401(k) plans allow after-tax (non-Roth) contributions beyond the $24,500 deferral, up to the $72,000 total limit, and allow those contributions to be converted to Roth in the plan or withdrawn to a Roth IRA. For a physician whose employer contributes $15,000, this can open more than $30,000 of extra Roth space a year. Check your plan document for after-tax contributions and in-service conversions.
Common mistakes
- Forgetting a SEP-IRA or old rollover IRA, which triggers the pro-rata rule.
- Not filing Form 8606, which can lead to double taxation later.
- Contributing to a Roth IRA directly with income too high, which creates an excess contribution penalty.
Frequently asked questions
Is the backdoor Roth still allowed in 2026?
Yes. Nondeductible IRA contributions and Roth conversions remain permitted, and both steps are reported on Form 8606.
Can residents contribute to a Roth IRA directly?
Usually. Most residents' income is below the Roth IRA phase-out, so they can contribute directly without the backdoor.
