That's right, you have to report the contribution (Form 8606) but not the conversion. There will be no tax for 2021. But if there was any gain between the time of the contribution and the conversion, then you will owe taxes on your 2022 return.

If you made nondeductible contributions to traditional IRAs for tax year 2021 then you need to file form 8606 but you won’t additional tax.

If you converted in calendar year 2022 you will report that on your taxes due 4/15/2023.

Otherwise I can’t really tell what you are asking.

I think I've just uncovered an issue in our 2021 taxes but I'm low on brain power and need a gut check.

It would appear we did not report our IRA contributions on our taxes.

We are not eligible for Roth IRA contributions, although we used to be. We have only been maxing IRA contributions for a few years.

I have a traditional IRA that is not converted.

My spouse has a Roth IRA from prior to us being ineligible, so this year we were able to convert the 2021 as a back door contribution and are doing the same for 2022 contribution / moving forward for his account. We did the conversion AFTER we had filed for this year, so not only did we not report the contribution but we also haven't reported the conversion. I think we owe additional taxes as a result?

Does this sound right? I want to correct this, but this stuff has always made my head hurt. I'm really not sure how we missed reporting the contributions in 2021. I need to check to see if we did in prior years or if we have been missing this all along. We do our own taxes with turbotax.

Appreciate any helpful guidance.
