So my husband and I filed jointly for many years. Now we got the Irma etc based on both incomes. Can we file separately this year they reapply using only his income ?

Hi. You and your husband can file separate tax returns, but whether or not that would reduce your Medicare premium rates depends in part on your respective income levels. I would suggest reviewing the information on Social Security's form SSA-44 (https://www.ssa.gov/forms/ssa-44-ext.pdf).

Furthermore, I have no way of knowing how filing separate tax returns would affect your income taxes. So, you may want to consult a tax expert before making any decisions.
