Several years ago I had a client who did the 60 day rollover in multiple pieces (Not trustee to trustee )
The rollovers were all done within 60 days, but the stock broker receiving the rollover funds dropped the ball on the paperwork.
The IRS took the position that the rollovers didn't qualify. My client was very late getting the IRS letters to me
After sending in all of the documentation 3 different times, the IRS agreed to most of the rollovers but insisted that about $ 2,000 didn't qualify and was taxable,
Finally I told my client that I had done everything that I could do and advised him that it was up to him to either pay the tax or to call the IRS himself.
A classic case of "how not to do rollovers!
