I think the 2024 nondeductible contribution was made in January 2025 - I put it on line 1 of the 8606 last year, so it was before filing. Line 2 was $98 left out of his original $100 nondeductible contributions from earlier years, so that equals $8098 and then line 4 was $8000 since it was made in 2025, line 6 was 0 since he converted all of his traditional IRAs by December 31 2024, so with the huge amount he converted in 2024, line 13 became $97 and line 14 became $8001 to carry over. So $8001 got put on line 2 this year, add in the $8000 he contributed in 2025, that's $16001 as I said, and since the 2025 contribution was made in 2025 not 2026 line 4 is 0 and line 5 is $16001 but line 8 was the $8004 and since they won't let you put anything larger than 1.0 on line 10, all that $8004 he converted this year is nontaxable, does that sound right? I was just surprised that he didn't have to pay tax on the $4. Then 16001 - 8004= 7997 is left on line 14 to carry over for the basis for next year? I went through the form and the instructions on the IRS website and though surprising, this seems correct?
