What’s a backdoor Roth IRA and how do I enter it?

Explains what a backdoor Roth IRA is, how it works when you’re over income limits, 2026 contribution limits, how it’s reported on Form 8606, and how to enter it correctly in april to avoid double taxation.


A backdoor Roth IRA is a tax strategy that lets you put money into a Roth IRA even if your income is too high to contribute directly.

Instead of contributing directly to a Roth IRA, you use an extra step—often called the “backdoor.”


How a backdoor Roth IRA works

Roth IRAs have income limits. If you earn over those limits, direct contributions aren’t allowed.

A backdoor Roth IRA uses two IRS-allowed steps:

  • Contribute after-tax money to a traditional IRA

  • Then convert that money from the traditional IRA to a Roth IRA

For 2026, the total amount you can contribute to traditional and Roth IRAs combined is:

  • $7,500 if you’re under age 50

  • $8,600 if you’re age 50 or older

Your contribution also can’t exceed your eligible taxable compensation for the year. These limits apply to contributions, not Roth conversions.


How it’s reported to the IRS

Form 8606 is used to report nondeductible traditional IRA contributions and Roth conversions. It tracks your after-tax basis so you’re only taxed on the taxable portion of the conversion—not the money you already paid taxes on.

Important: If you have other Traditional, SEP, or SIMPLE IRA balances, part of your conversion may be taxable under IRS rules, even if you made an after-tax contribution.


How to enter a backdoor Roth IRA in april

You’ll be asked about your retirement income. Enter the information from Form 1099-R, which is sent by the financial institution that processed the IRA distribution.
​

Next, answer questions about whether the distribution was rolled over and converted to a Roth IRA.
​

If applicable, we’ll ask for additional details about after-tax IRA contributions (basis) to help prevent double taxation.


Not sure what to enter?

If a question doesn’t apply to you, $0 may be the correct answer. However, if you made nondeductible IRA contributions or have an existing IRA basis, it’s important to enter the correct amounts.
