What is used to determine the tax year for reporting a distribution - is it the distribution check date or the settlement date for the request? Trying to confirm what is correct for end of year distribution requests. For example, if a distribution is requested (on plan website) on December 30, 2013and the trades settle on December 31, 2013 and the check is issued and dated January 2, 2014, should the 1099-R be a 2013 form, or a 2014 form?
What is the key date - settlement or check? I know that constructive receipt is noted in ERISA Online, but references do not specifcally note for tax reporting purposes(for 1099-R reporting).
