In prior posts/threads, it appears that MAGI for determining Medicare premiums is just AGI plus tax-free dividends, and not other things like the part of Social Security that's not in the AGI. I'd like to verify this is still the case for 2022 (which will determine 2024 premiums)m since I'm getting ready to do a conversion to Roth and want to keep it under the limit for lowest Medicare premium bracket. Thanks for any info.
