I’ve been regularly doing a ‘backdoor Roth’ conversion as my income is around or sometimes above the Roth conversion threshold.
My father passed away in April and left me, in part, a decent sized though not enormous traditional IRA. That, plus the other funds I moved/planned to move around has realized some capital gains which means I’ll likely be above the threshold (“unfortunately”, some of those funds came from an irrevocable trust, and as such didn’t get the step up in basis, so they have gains).
Anyway, I’m wondering, I know for tax/basis purposes, all IRAs you own are treated as one. So if you have another traditional IRA with no basis, that will impact the taxable portion of the Roth conversion.
My question is, does this include the Inherited IRA and it will prevent me from doing the ‘backdoor Roth’ maneuver?
Looking at the form 8606 instructions, I’m thinking no - the Inherited IRA is accounted for separately? I’m thinking this because the line 2 instructions for form 8606, don’t mention inherited IRAs and simply point you back to last year Form 8606 for the basis, not saying to count any value from anything inherited. And line 6 instructions say to include “Enter the total value of all your traditional, traditional SEP,
and traditional SIMPLE IRAs” (emphasis mine).
And then if I look up the information about inherited IRAs in Pub 590-B, it says:
If you inherit a traditional IRA from a person who had a basis in the IRA because of nondeductible contributions, that basis remains with the IRA. Unless you are the decedent’s spouse and choose to treat the IRA as your own, you can’t combine this basis with any basis you have in your own traditional IRA(s) or any basis in traditional IRA(s) you inherited from other decedents. If you take distributions from both an inherited IRA and your IRA, and each has basis, you must complete separate Forms 8606 to determine the taxable and nontaxable portions of those distributions.
So this seems to say, athough not addressing this exact situation, that the Inherited IRA is treated separately on it’s own Form 8606, and therefore doesn’t impact my ability to do my own nondeductible IRA->Roth conversion.
Did I piece that together correctly?
And if so… what’s the chance that my tax software will do it that way… lol.
