Backdoor Roth IRA for High-Income Earners: A Step-by-Step Guide

For high-income earners, directly contributing to a Roth IRA may be off the table due to IRS income limits.

But there's a legal workaround: the Backdoor Roth IRA.

This strategy allows individuals who exceed the Roth income thresholds to fund a traditional IRA and then convert it into a Roth, unlocking tax-free growth potential.

In this guide, we’ll walk you through exactly how to execute a Backdoor Roth IRA — step by step — without triggering unnecessary taxes.

πŸ‘€ Who Needs a Backdoor Roth?

In 2025, the income phase-out for direct Roth IRA contributions begins at:

- $146,000 for single filers

- $230,000 for married filing jointly

If your modified adjusted gross income (MAGI) exceeds these levels, you can’t contribute directly to a Roth IRA — but you can use the backdoor method.

This strategy is ideal for professionals, business owners, or anyone in high tax brackets seeking tax-free retirement growth.

πŸͺœ Step-by-Step: How It Works

Step 1: Open a Traditional IRA (non-deductible contribution)

- You can contribute up to $7,000 ($8,000 if age 50+ in 2025)

Step 2: Wait a few days (not required by law, but may reduce flags)

Step 3: Convert the Traditional IRA to a Roth IRA

- You may owe taxes if you have pre-tax funds in other IRAs (see Pro-Rata Rule)

Step 4: Report everything on IRS Form 8606 to avoid double taxation

🧾 Form 8606: Your Key to Compliance

IRS Form 8606 reports non-deductible IRA contributions and Roth conversions.

Filing this form properly is crucial — it documents your basis and prevents double taxation.

If you don’t file Form 8606, you could owe tax on money you already paid tax on.

πŸ“Š The Pro-Rata Rule Explained

This rule determines how much of your Roth conversion is taxable.

If you have other pre-tax IRAs (Traditional, SEP, or SIMPLE), the IRS looks at your total IRA balances when calculating the taxable portion of your conversion.

Example: If 80% of your IRA funds are pre-tax, 80% of your conversion will be taxed — even if the contribution you made was post-tax.

Workaround: Roll pre-tax IRA funds into a 401(k) before doing the conversion (401(k) balances don’t count in the pro-rata rule).

⚠️ Common Mistakes to Avoid

- Forgetting to file Form 8606

- Not checking for existing IRA balances

- Assuming conversions are tax-free without understanding the pro-rata impact

- Contributing more than the annual limit

- Waiting too long between contribution and conversion (market gains may cause unexpected taxes)
