How do backdoor Roth IRA conversions work in 2026? Any pitfalls?
My spouse and I have a combined income of about $310,000, which puts us well above the Roth IRA income limits. I've heard about the 'backdoor Roth' strategy where you contribute to a traditional IRA and then convert it to a Roth.
A few questions:
- Is this still allowed in 2026 with current tax law?
- The pro-rata rule confuses me — I have about $85,000 in a rollover IRA from a previous 401(k). Will that cause problems?
- If I convert immediately after contributing (same day), does that avoid any tax issues?
I want to make sure I don't accidentally create a tax mess.

The backdoor Roth is still alive and well in 2026. Here's the key thing: the pro-rata rule is your real enemy here.
With $85k in a rollover IRA, if you contribute $7,000 (non-deductible) and convert $7,000, the IRS treats your conversion as proportional. So about 92% ($85k/$92k) of your conversion would be taxable. That's about $6,440 of taxable income on a $7,000 conversion — not great.
Solutions:
- Roll your rollover IRA into your current 401(k) if the plan allows it. Then you have $0 in traditional IRAs and the backdoor works cleanly.
- Convert the entire $85k + $7k in one year (big tax bill upfront but clears the path)
- Just use a taxable brokerage — at your income level, tax-efficient ETFs are quite good
Option 1 is usually best if your 401(k) has decent investment options and accepts rollovers.
