The Internal Revenue Code allows individuals who receive a distribution from an IRA to avoid tax consequences by rolling the funds over to an IRA within 60 days. However, to avoid abuse of the rule, the tax code prescribes that taxpayers can only complete an IRA rollover once in a 12-month period, which the IRS in the past has interpreted to apply to IRAs on an account-by-account basis. In turn, the "separate accounts" treatment of the IRA rollover rule potentially allows taxpayers to chain together multiple IRA rollovers, in an attempt circumvent the 1-year rule and gain "temporary" use of IRA funds for an extended period of time.
However, a recent Tax Court case, Bobrow v Commissioner, has shut down the separate IRAs rollover strategy altogether. In a case that started out as a taxpayer who botched a version of the sequential separate accounts rollover strategy, and drew the IRS' ire in the process, ended out with a finding of guilt for not only of botching the rollovers but having the Tax Court (re-)interpret IRC Section 408(d)(3)(B) as well. In the decision, the Tax Court applied the 1-year IRA rollover rule to apply in the aggregate across all IRAs, invalidating the separate IRA rollover treatment not only for Bobrow but all taxpayers as well!
In the aftermath of the Bobrow case, the IRS has now issued IRS Announcement 2014-15, stating that it will acquiesce to the Tax Court decision, update its Proposed Regulations and Publication 590, and issue new Proposed Regulations soon that will definitively apply the 1-year IRA rollover rule on an IRA-aggregated basis going forward. However, to allow time for transition - including taxpayers in the midst of rollovers left in the lurch, and IRA custodians who must update their own processes and procedures - the IRS has declared that the "existing" rules will be allowed through the end of the year. However, the new rules allowing only one IRA rollover in a 1-year period will be effective starting January 1, 2015 (potentially dating back to IRA rollovers that occur in 2014), so advisors and their clients should plan accordingly!
