- You assumed ownership and converted to a Roth $3,700 inherited pre-tax traditional IRA assets.
- You made a $6,500 2016 non-deductible traditional IRA contribution, will make a $6,500 2017 non-deductible traditional IRA contribution and will do a Roth Conversion of both of those contributions and any earnings.
There are two filings that both Johanna and your CPA seem to agree with:
- You will file a 2016 Form 8606 to report the 2016 $6500 non-deductible contribution as basis. You do this because this was a 2016 contribution even though it was made in in 2017. There is no 2016 taxable impact of this reporting.
- You will file a 2017 Form 8606 to report the 2017 $6,500 non-deductible contribution to add to the basis (now $11,000) and report the $3,700 and any earnings on the non-deductible contributions as taxable amounts. This will flow through to your 1040 as taxable income.
The difference is whether an 1040X amended return is required or not. The Form 8606 instructions are ambiguous on whether a 1040X is required or not. Most financial professionals, tax professionals and individuals have been filing solo 8606 forms for decades without problem. However, there have been some recent insignificant percentage, but persistent anecdotal reports of the IRS requesting resubmittal of the Form 8606 with an accompanying Form 1040X. This has caused some professionals to supply the 1040X proactively to avoid the panic calls from the client.
So the short answer is that both Johanna and your CPA are probably both right from their experience and perspective.
Here is my situation:
1. On 01/31/16 I had NO money in traditional IRA and NO roth IRA
2. On 01/10/17 I transferred 3.7k from my deceased husbands account to my traditional IRA (?inherited)
3. On 03/10/17 I converted 3.7k to roth IRA for 2016
4.. Now I deposited 6.5k (I am 50 yo) to traditional IRA and plan do backdoor conversion to roth IRA for 2016
5. Little bit later plan to do backdoor conversion of 6.5 k to roth IRA for 2017
Question: how do I fill out 8606 for 2016, especially that I already filed taxes?
What numbers do I put on each line in form 8606?
Thank you
