No. If the initial 72t plan Permalink Submitted by Alan-iracritic@... on Wed, 2020-08-12 13:13 No. If the initial 72t plan distribution is in December, you must use your attained age in that same year. Certain special rules (eg SS benefit calc for 1/1 DOBs) do not apply here. Same thing with the interest rate. If your distribution is reported on a 1099R for a year and it's a December distribution, the applicable highest interest rate is for Oct or Nov, not December. In determining applicable dates, you should use the date of the distribution as reported by the custodian, not the possibly later date you received the distribution. Got it!
