What Is Backdoor Roth IRA?
A backdoor Roth IRA lets high earners contribute to a Roth IRA indirectly by converting a Traditional IRA contribution. Learn the steps and tax implications.
Definition
A backdoor Roth IRA is a legal strategy that allows high-income earners who exceed the Roth IRA income limits to contribute to a Roth IRA indirectly. The process involves two steps: (1) make a non-deductible contribution to a Traditional IRA, then (2) immediately convert that Traditional IRA to a Roth IRA. Since the contribution was non-deductible (after-tax money), the conversion is mostly or entirely tax-free.
The income limits for direct Roth IRA contributions are $161,000 for single filers and $240,000 for married filing jointly (2026). If you earn above these limits, you cannot contribute directly. But there are no income limits for Traditional IRA contributions (they just are not deductible at high incomes) and no income limits for Roth conversions. The backdoor Roth exploits this gap.
The main complication is the "pro rata rule." If you have existing pre-tax money in any Traditional IRA, the IRS treats all your Traditional IRA money as one pool for conversion purposes. You cannot convert just the after-tax portion. This means the backdoor Roth works cleanly only if you have zero pre-tax Traditional IRA balance. If you do have pre-tax money, consider rolling it into a 401(k) first.
Real-World Example
You earn $250,000 and cannot contribute directly to a Roth IRA. You open a Traditional IRA and contribute $7,000 (non-deductible). The next day, you convert the entire $7,000 to a Roth IRA. Since the contribution was after-tax and there was no growth (you converted immediately), there is no tax owed. You now have $7,000 in a Roth IRA growing tax-free forever. Repeat every year.
Why It Matters
The backdoor Roth is one of the most powerful tax planning strategies available to high earners. Roth IRA money grows tax-free, is not subject to RMDs, and can be passed to heirs with significant tax advantages. Over a 20-30 year career, consistently using the backdoor Roth can accumulate hundreds of thousands of dollars in tax-free savings. It is legal, well-established, and used by millions of Americans -- though it has been targeted for elimination by some congressional proposals.

Frequently Asked Questions
Is a backdoor Roth IRA legal?
Yes. It has been legal since Roth conversions became available in 2010. The IRS is aware of the strategy, and Congress has considered eliminating it but has not done so. It is widely used and considered mainstream tax planning.
What is the pro rata rule?
The pro rata rule requires that Roth conversions include a proportional share of pre-tax and after-tax money from ALL your Traditional IRAs. If you have $93,000 pre-tax and $7,000 after-tax in Traditional IRAs, only 7% of any conversion is tax-free. To avoid this, roll pre-tax IRA money into a 401(k) first.
Can I do a backdoor Roth every year?
Yes. You can do it annually as long as you are within the Traditional IRA contribution limits ($7,000/$8,000 for 2026). There is no limit on the number of Roth conversions you can do.
