Retirement tax questions

You don't have to worry about a 2015 RMD, but you do have to consider your options for 2016 and beyond. You had the option to take an RMD in 2016 to spread the IRA distributions over your lifetime.
Since 2016 is over, you may not have that option any longer. (dmertz is the expert).
See IRS PUB 590-B available at <a rel="nofollow" target="_blank" href="http://www.irs.gov">www.irs.gov</a> for your options.
