Generally, in order to avoid current taxation, a taxpayer must roll a distribution received from an employer plan or IRA to another plan or IRA within 60 days after receiving the distribution. The IRS has the ability to waive the 60-day limit in certain circumstances. However, a private letter ruling from the IRS was usually needed to obtain that relief.
In Rev. Proc. 2016-47 the IRS has now provided a simpler “self-certification” procedure that allows taxpayers who meet one of 11 criteria to make a late rollover without seeking a private letter ruling (subject to later IRS audit).
