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

4 min read · April 2026 · HaraPro Team

If your income exceeds the Roth IRA contribution limits ($161,000 for single filers, $240,000 for married filing jointly in 2026), you can't contribute directly. But there's a legal workaround that takes about 15 minutes and lets you get $7,000 per person into a Roth every year.

It's called the Backdoor Roth IRA, and the IRS knows about it.

How It Works (2 Steps)

Step 1: Contribute to a Traditional IRA

Contribute $7,000 to a Traditional IRA. At your income level, this contribution is non-deductible — you don't get a tax deduction for it. That's fine. The goal isn't the deduction.

Step 2: Convert to Roth IRA

Immediately convert the Traditional IRA balance to a Roth IRA. Since you contributed after-tax dollars (non-deductible), the conversion is tax-free on the contribution amount. Any minimal gains between steps would be taxable.

💡 Key: Do the conversion immediately. Don't invest the Traditional IRA funds first. Convert the same day or next business day. This minimizes any taxable gains between contribution and conversion.

Who Should Do This?

The Pro Rata Rule (Watch Out)

⚠️ If you have existing pre-tax IRA balances (Traditional IRA, SEP IRA, SIMPLE IRA), the IRS applies the "pro rata rule" — your conversion will be partially taxable based on the ratio of pre-tax to after-tax IRA money across ALL your IRAs.

Example: You have $93,000 in a SEP IRA (pre-tax) and contribute $7,000 to a Traditional IRA (after-tax). Total IRA balance: $100,000. Only 7% is after-tax. So 93% of your conversion is taxable.

The Fix: Roll Pre-Tax IRAs Into a 401(k)

If your employer or your own S-Corp/LLC has a Solo 401(k), roll your SEP IRA and Traditional IRA balances into it. This removes the pre-tax IRA balance from the pro rata calculation, making your backdoor conversion clean.

The Long-Term Impact
