Did they release the IRMAA brackets?
Applying 5.9 percent gives single $94K, $118K, $147K, $175K, married $188K, $236K, $292K, and $350K. These brackets are rounded up to the nearest thousand.
It just occurred to me that they will probably be increasing the IRMAA amounts as well. Both this, and the standard premiums, won’t be announced until later in the year.
