Retirement tax questions

It is death of spouse very close to year-end, so income in year of death is almost normal level, but going forward will be greatly reduced.

 

I am concerned about maybe waiting too long after death to apply for IRMAA reduction or also risking that IRMAA will kick in for several months before I will get any resolution, which may cause me a cash crunch in the short term.

 

My plan was to file the 2023 return, then file the SSA-44.  So, Q1 2024.  The IRMAA notice would not normally be in my hands until December 2024.  Thought I would be proactive about it.
