Where to enter your backdoor Roth in TurboTax

TurboTax walks you through backdoor Roth conversions using the IRA section, not the Roth IRA section. When you convert money from a traditional IRA to a Roth IRA, TurboTax treats it as a distribution from the traditional IRA first, then a contribution to the Roth. You report both sides of the transaction, and the software guides you through each step in order.

Start in the Federal Taxes section. Look for "IRA, Pensions, Annuities" or similar wording depending on your TurboTax version. From there, you will see a question about whether you received a distribution from an IRA. Answer yes, and TurboTax will ask you to enter the amount you converted. This is where you report the money leaving your traditional IRA.

After you report the distribution, TurboTax will ask about contributions to a Roth IRA. This is where you report the same money coming into your Roth. The software will calculate Form 8606, which is the IRS form that tracks your backdoor Roth and makes sure you do not pay tax twice on the same dollars.

Key Takeaways

  • Report the backdoor Roth as a traditional IRA distribution first, then as a Roth contribution, using the IRA section of TurboTax.
  • TurboTax automatically generates Form 8606, the form the IRS uses to track conversions and pro-rata calculations.
  • If you have other traditional IRAs, SEP IRAs, or straightforward IRAs, you must report their balances on December 31 of the tax year, or TurboTax will calculate your tax bill incorrectly.
  • The conversion amount is taxable only if you have pre-tax money in any traditional IRA account, which TurboTax calculates using the pro-rata rule.
  • Keep your IRA custodian statements and the 1099-R form your bank sends you, because TurboTax will ask you to match the numbers.

Entering the distribution amount from your traditional IRA

When TurboTax asks for the IRA distribution, enter the gross amount you converted — the full dollar amount that left your traditional IRA account, before any taxes or fees. Do not subtract anything. Your bank or brokerage will send you a Form 1099-R showing this amount in Box 1, and TurboTax will ask you to confirm it matches.

TurboTax will then ask whether this distribution was a rollover or a conversion. Select conversion. The software will ask what type of IRA you converted to; select Roth IRA. At this point, TurboTax knows you are reporting a backdoor Roth and will set up the rest of the form correctly.

If you converted only part of your traditional IRA balance, enter only the amount you converted, not the full account balance. TurboTax will ask you to enter the balance remaining in the account on December 31 of that tax year. This number is critical: it is used to calculate the pro-rata rule, which determines how much of your conversion is taxable.

Reporting the Roth contribution side of the conversion

After you finish the distribution section, TurboTax will ask about Roth IRA contributions. Enter the same dollar amount you converted. TurboTax will ask whether this is a regular contribution or a conversion contribution; select conversion. The software will then ask what year the conversion happened; select the current tax year.

TurboTax may ask whether you made any other Roth contributions that year. If you also made a regular $7,000 contribution to your Roth (or whatever the annual limit is), report that separately. The conversion and the regular contribution are two different lines on Form 8606, and TurboTax needs both to calculate your tax correctly.

Do not enter the Roth contribution in the "Contributions" section of TurboTax — that section is for regular annual contributions only. The conversion goes in the "Distributions and Conversions" section, where TurboTax will automatically route it to Form 8606.

Understanding the pro-rata rule and Form 8606

Form 8606 is the IRS form that tracks your backdoor Roth and calculates whether any part of your conversion is taxable. The pro-rata rule says that if you have pre-tax money in any traditional IRA, SEP IRA, or straightforward IRA on December 31 of the tax year, a portion of your conversion will be taxable. TurboTax calculates this automatically, but only if you tell it about all your IRA accounts.

When TurboTax asks for the balance in your traditional IRA on December 31, enter the exact balance from your year-end statement. If you have a SEP IRA or straightforward IRA, TurboTax will ask about those too. If you have multiple accounts at different banks, add them all together and enter the total. TurboTax will use this number to calculate what percentage of your conversion is taxable.

For example: if you have $50,000 in a traditional IRA and you convert $10,000, the pro-rata rule says that 83% of your conversion ($50,000 divided by $60,000) is pre-tax money. That $8,300 is taxable income in the year you convert. TurboTax calculates this on Form 8606 and adds it to your taxable income automatically. If you forget to report the $50,000 balance, TurboTax will calculate zero tax on the conversion, which is wrong and will trigger an IRS notice.

Common mistakes when reporting in TurboTax

The most common mistake is entering the conversion in the wrong section. Some people put it in the regular Roth contribution section, which does not trigger Form 8606. TurboTax will then calculate your tax bill as if you made a regular contribution, not a conversion, and you will owe money when the IRS audits you. Always use the "Distributions and Conversions" section, not the "Contributions" section.

The second mistake is forgetting to report other IRA accounts. If you have a traditional IRA at one bank and a SEP IRA at another, you must report both balances on December 31. If you only report one, TurboTax will calculate the pro-rata rule incorrectly and you will either overpay or underpay your taxes. Check all your statements from December 31 before you enter anything into TurboTax.

The third mistake is entering the net amount instead of the gross amount. If your bank charged you a $50 fee to process the conversion, do not subtract it from the amount you enter into TurboTax. Enter the full amount that left your traditional IRA. The fee is a separate deduction that you may be able to claim elsewhere on your return, but it does not reduce the conversion amount on Form 8606.

Matching your 1099-R form to TurboTax

Your bank or brokerage will mail you a Form 1099-R showing the conversion. Box 1 shows the gross distribution amount. Box 2a shows the taxable amount, which your bank calculates using the pro-rata rule if you told them about your other IRA accounts. Box 7 will show code G, which means "Distribution from a Roth conversion." TurboTax will ask you to enter these numbers and confirm they match your 1099-R.

If the taxable amount on your 1099-R does not match what TurboTax calculated, do not panic. Your bank may have calculated the pro-rata rule differently than TurboTax, or you may have told your bank something different than you told TurboTax. The IRS uses Form 8606 (which TurboTax files) as the official record, not the 1099-R. If your numbers are different, enter what TurboTax calculated and keep a note explaining why.

If you made a mistake on a prior year's backdoor Roth and the 1099-R was wrong, you can file Form 8606 to correct it. TurboTax can help you amend a prior return, but you may want to talk to a tax professional first because the pro-rata rule can be tricky to recalculate.

What happens after you file

Once you file your return with Form 8606, the IRS has a record of your backdoor Roth conversion. The IRS does not send you a confirmation, but you should keep a copy of your filed return and your Form 8606 for your records. If you do a backdoor Roth every year, you will file a new Form 8606 every year, and each one will show the cumulative balance in your traditional IRAs.

The IRS matches Form 8606 against the 1099-R your bank sends them. If they do not match, you may receive a notice asking you to explain the difference. This is why it is important to keep your bank statements and your 1099-R forms. If you receive a notice, you can send the IRS a copy of your Form 8606 and explain any differences.

Frequently Asked Questions

Do I need to file Form 8606 separately, or does TurboTax file it for me?

TurboTax files Form 8606 with your tax return automatically. You do not need to mail it separately or file it by hand. When you complete the IRA distribution and conversion questions in TurboTax, the software generates Form 8606 and includes it in your electronic filing.

What if I converted money but did not receive a 1099-R?

Contact your bank or brokerage and ask them to send you a 1099-R. If they say they did not issue one, ask them why — some custodians are slow to send them, and some make mistakes. You still need to report the conversion to TurboTax even if you do not have the 1099-R yet. You can file your return and amend it later if the 1099-R arrives with different numbers.

Can I report a backdoor Roth if I have a 401(k) at work?

Yes. The pro-rata rule only applies to traditional IRAs, SEP IRAs, and straightforward IRAs. A 401(k) is separate, so it does not affect your backdoor Roth calculation. However, if you have a traditional IRA, you must report its balance even if you also have a 401(k).

What if I converted to a Roth but the money is still sitting in my traditional IRA account?

Contact your bank when ready. A conversion means the money must move from the traditional IRA to the Roth IRA. If it is still in the traditional IRA, the conversion did not complete. Your bank may have processed it as a transfer instead of a conversion, or there may have been a delay. Ask them to confirm the money arrived in your Roth account and when.

Do I have to report a backdoor Roth every year?

Only in the years you actually do a conversion. If you convert in 2024 but not in 2025, you file Form 8606 in 2024 but not in 2025. Each conversion is reported separately on its own Form 8606 in the year it happens. TurboTax will only ask you about conversions in years when you tell it you did one.
