I don't see taxable social security income and tax exempt interest on this worksheet. Both show up on my 1040 and are included in my adjusted gross income (AGI).
As far as I know, both should be included in the MAGI calculation (added to AGI).
So I am not sure what the purpose of that worksheet is as it underreports MAGI.
This is critical as MAGI determines IRMAA premiums (adjustments to Medicare premiums) which could be quite high for high income filers.
