I've just realized my income is probably going to exceed one of the Medicare income related monthly adjustment amount (IRMAA) thresholds, which will add about $2,000.00 ($1K for me and my wife each) to our Medicare cost next year. I've maxed out my $25K of Roth 401K contributions, but now realize that: if those had been traditional pre-tax 401K contributions, then I probably would stay below the threshold. Is there any way to convert those Roth contributions back to traditional pre-tax type contributions if it is done before year end? The taxes paid could be recovered when the tax return is filed.
