Backdoor Roth IRA for High Earners

If your income is above the direct Roth IRA limit, you are not locked out of tax-free retirement growth. The backdoor Roth IRA is a two-step process that still works for most high earners, even after recent tax-law conversations.

How it works

Step one: make a non-deductible contribution to a traditional IRA. Step two: convert that contribution to a Roth IRA. Because the original contribution was after-tax, the conversion is usually tax-free, assuming you have no pre-tax IRA balances.

The pro-rata rule

The pro-rata rule is the detail that trips people up. If you have any pre-tax traditional IRA, SEP, or SIMPLE IRA balances, the IRS treats the conversion as coming proportionally from pre-tax and after-tax money. That can make most of the conversion taxable. The fix is often to roll pre-tax balances into a current employer 401(k) before using the backdoor.

Mega backdoor Roth

Some employer 401(k) plans allow after-tax contributions well above the standard deferral limit, plus in-plan Roth conversions or in-service withdrawals. This is the mega backdoor Roth, and it can move tens of thousands more dollars into Roth accounts each year. Not every plan allows it, so check your summary plan description.

When to skip it

If you have large pre-tax IRA balances and no employer plan to roll them into, the backdoor Roth may not be clean. In that case, a Roth conversion analysis, deductible retirement contributions, or taxable investing might be better first steps.

The backdoor Roth is not a loophole. It is a documented process that requires careful execution. Done right, it adds tax-free growth to a retirement plan that is otherwise capped by income.
