Get your taxes done using TurboTax

Yes, generally a conversion from a traditional IRA to Roth IRA is taxable because you move pre-tax funds into an after-tax account. But for the backdoor Roth strategy you make nondeductible contributions to the traditional IRA and therefore these are after-tax contributions and you will have a basis in the traditional IRA. If someone converts the contribution right away and only had nondeductible contributions then the full amount converted will be nontaxable because there were no earnings.

Please do not enter the Roth conversion amount as a Roth IRA contribution. You only will enter an IRA contribution (traditional or Roth) if you made one for 2022.

If you only made deductible contributions to your traditional IRA then your conversion will be fully taxable. Do not enter that you had a basis in prior years.
