If your income is too high to contribute directly to a Roth IRA, you can still get money in there through a two-step process called a backdoor Roth conversion. It's legal, common, and explicitly allowed by the IRS.
How it works
- Contribute to a Traditional IRA (no income limit on contributions)
- Convert that Traditional IRA to a Roth IRA
- Pay tax on any gains between contribution and conversion (usually pennies if you do it quickly)
The result: money in your Roth IRA, growing tax-free for the rest of your life.
The pro-rata rule trap
If you have any pre-tax money in any Traditional IRA, SEP IRA, or SIMPLE IRA, the IRS makes you convert proportionally, meaning part of your conversion gets taxed. This is the most common backdoor mistake.
The fix: roll any existing pre-tax IRA money into your current employer's 401(k) before doing the backdoor. 401(k) balances don't count toward the pro-rata calculation.
Don't do this without help the first time
The mechanics involve specific IRS forms (Form 8606) and timing rules. A CPA fee for the year you start a backdoor Roth is well worth it. Once you understand the cycle, you can do it yourself in subsequent years.
What this lesson is NOT
This is not tax advice. The backdoor Roth has real complications, most importantly the pro-rata rule, which can create a surprise tax bill if you hold other pre-tax IRA money. It is not a fit for everyone, and it depends on current law. Talk to a tax professional before doing one.
