I'm doing some forward looking planning and I need some guidance on how RMD's are determined. Here is my example: during the calendar year I withdraw $7,500 quarterly (for immediate cash flow requirements) from my IRA as $30,000 would be a close approximation to my RMD determined at the end of the year. If I make these withdrawals, will the administrator recognize them as satisfying my RMD for the year, or will the end of the year RMD calculation still take place. If the answer is the latter then essentially I will have received combined distributions which would double my intended withdrawal. Am I missing something?
