Thank you. My 8606 does show the $8000 as a basis with previous basis being 0. My husband's (he has not yet made his contribution but will before April 15) shows $8000 (planned) and $98 basis (because he had previously made a $100 nondeductible contribution, and converted part of his IRA in 2023 and the rest in 2024, so his traditional IRA balance at the end of 2024 was 0). His nontaxable portion of the 2024 conversion is shown as $97, and his basis for 2024 is now $8001?? Even though once he makes his $8000 contribution he will only have $8000 in the traditional IRA? My basis for 2024 and earlier years (line 14) is the $8000 that I contributed earlier this year for 2024. So when I get my 1099-R for 2025, showing I converted $9000.03, $1000.03 (the $1000 deductible that was left in my traditional IRA at the end of 2024 plus the $0.03 interest I earned - but didn't get credited, so I had to convert that separately - before I converted the $8000 this year) will be taxable? But he can earn up to $1 in interest between his contribution and his backdoor conversion and have it not included in taxable income for 2025?
