[OR decide to file an extension AND delay my decision/pmt to Oct. /quote] I knew you could delay the payment; I was unaware you could also delay the decision. Interesting strategy.
The rules for recharacterization are complicated. I recommend discussing this with your CPA. Also I believe that it is not necessarily based on the pps on April 15th but rather it is the date that you recharacterize but again your CPA is the best place to get personal advice. BTW besides a penalty of $75.00 for late payment the interest charges are very reasonable.
