Has anyone had any experience with the iRS regarding recoveries of withholding overpayments made by a pension plan or is aware of any guidance? For example, assume that a pension plan continues to pay benefits to a deceased retiree's bank account and the joint holder of the account retains the funds or the funds are returned to the plan by the bank. An IRS letter dated May 15, 2003 from the Office of Chief Counsel entitled "IRS Letter on Recovery of Erroneous Withholding" states that the plan can file Forms 843 and 941c (apparently Form 941c was replaced by Form 941-X). The guidance contained in this May 15, 2003 letter appears out of date. And it would appear that IRS Form 945x is more appropriate.
