My broker checked with TWO different accountants and said the same thing. I then asked my accountant of 35 years the same thing. He concurred. This applies to a 401k and the IRA. You will recieve a form in the mail and you give it to your tax preparer and forget about it.
I have held KMP in an IRA for ten years with no problem. I also have EPD, MWE, & NS. I have to take a distribution because of my age, and it really works out well with the distributions MLP's pay. spacuna
