Beware, one misstep could cost you a whole lot of money. I'm not sure how this will pan out but I had 2 advisor-sold 529 accounts for my child (one at the Maine NextGen and the other at the VA CollegeAmerica plan). In leaving my old advisor, I thought it would be easy to consolidate the 2 529s and move to a new NON-advisor plan (NY Savings Plan). Well, after the fact, in speaking with my new CPA, it turns out that I should have only rolled over one of the plans and left the other one in tact for 12 months since only one "rollover" is permitted per 12-month period. I am now facing a potentially huge tax bill on the earnings portion plus the penalty. I found this out 2 weeks after the rollovers both occurred and both fund companies refuse to "unwind" the rollovers. This is all fresh, and I am willing to correct this mistake, yet I cannot find a CPA, tax attorney, nor any live human at the IRS or anyone who can let me if there is a way to "fix" my mistake. I realize in hindsight the error I made in not consulting with a CPA or someone experienced beforehand, and now I am going to pay for that severely for what I thought was simple effort to consolidate my accounts and move funds away from the old advisor. What is more, is that if I start taking 529 "qualified distributions" from the NEW plan, the state I live in will STILL consider the 529 withdrawals as unqualified since I did not take the withdrawals from the 529 plan issued by my state. So I get penalized again since my state of residence is FORCING me to use their plan amidst other plans that are better out there. UNFAIR!
