As far as Ed Slott's article, it is fine as far as it goes. We have no guidance from IRS addressing this issue, and probably won't get any before year-end. I believe conversions done in taxable year 2017 can still be recharacterized by the October 15, 2018 deadline, as that transaction applies to taxable year 2017 - not 2018. In fact, the taxpayer must attach an explanation of the transaction to his/her 2017 return. However, if there is no IRS guidance before year end, and if there is a significant amount of money involved, taxpayers will have to decide whether to take a chance that the law will be interpreted that way. This can be a catch-22 for some individuals, because they may very well want to convert in 2017 for tax reasons, but still have the option to recharacterize in 2018 if their converted assets lose value.
