I have a related issue that maybe someone can answer. I have an old DB plan with a plan year beginning 12-31 and ending 12-30. For a variety of issues, one being they have a DC plan that I would like to be able to test together with this plan, I want to change the plan year to a calendar year. I seem to remember, long ago pre PPA, that the IRS didn't care about the 1 day.
Can I have a plan year going from 12-31 to 12-31 (366 days) and then start the next year on 1-1? That way I don't have to worry about a valuation and sched B for the 1 day. Nothing changes - my val date remains the first day of the plan year - except the plan year, which I can do by amendment.
IS this kosher? any feedback would be appreciated. THANKS
