Pages 31-32 of Pub 590-B say that there's a separate 5-year period for each conversion from traditional to Roth IRA, and early distributions "may" have to pay a 10% additional tax. Page 32 says "you may not have to pay the 10% additional tax in the following situations," and the first one listed is "You have reached age 50½." Those "may"s make me nervous.
I'm over 72, and I established my Roth in the 2015 tax year. On the flowchart on page 34, I can answer Yes to the first two boxes "Has it been at least 5 years from the beginning of the year for which you first set up and contributed to a Roth IRA?" and "Were you at least
59½ years old at the time of the distribution?". Therefore, according to the flowchart, _every_ distribution from my Roth will be a qualified distribution.If I do a Roth conversion but then need the money only a couple of years later, can I rely on the flowchart, with no need to worry about the "may"s on pages 31-32?
