Distributions of conversion and certain rollover contributions within 5-year period.
If, within the 5-year period starting with the first day of your tax year in which you convert an amount from a traditional IRA or roll over an amount from a qualified retirement plan to a Roth IRA, you take a distribution from a Roth IRA, you may have to pay the 10% additional tax on early distributions. You must generally pay the 10% additional tax on any amount attributable to the part of the amount converted or rolled over (the conversion or rollover contribution) that you had to include in income (recapture amount). A separate 5-year period applies to each conversion and rollover. See Ordering Rules for Distributions, later, to determine the recapture amount, if any.
