I’m considering ?starting Roth conversion?s? this year. One of the factors I’m considering is IRMAA. I retired at 61 and I will be 63 in November. My understanding is that AGI (plus some other ?misc ?items) on my 2022 tax return will be used to determine my IRMAA when I’m eligible for Medicare in Nov 2024.
Will my 2022 tax return be used to calculate irm?aa for just? two months (Nov and Dec 2024?)? and then my 2023 return for 2025? IRMAA?, or ?will the 2022 return ?be ?used for 12 months?
?In general, I’m struggling to determine if it makes sense for me to do Roth conversions. Between changing tax rates, IRMAA, expected portfolio returns, ACA premiums (which I will need to use for one year and my wife for 5 years before she is eligible for Medicare)? etc, it seems there are many factors and unknowns to take into consideration.
If I attempt to model this out with a convoluted spreadsheet, am I missing any significant factors to what I listed above? Or, am I overthinking this and should really just focus on our tax rate at the time of conversion versus the expected income and tax rate when we start taking RMDs?
