I bought retirement credit for a couple of years of previous service as a teacher. I used funds from an IRA and they were deposited almost immediately in to the retirement fund. The problem is that I did not rollover the funds directly from the IRA in to the retirement fund. The fund has coded my deposit as a post tax contribution and now the IRS is calling it taxable. Any ideas on how I can prove that this was an innocent attempt to move retirement funds and prevent it from being a taxable event?
