I have an extremely large MAGI on california form 3853. Where it is calculated? The value doesn't show up anywhere else on other forms.

[JohnW152]

To calculate your MAGI for purposes of the Individual Shared Responsibility Penalty, add:

• Your adjusted gross income amount reported on Form 540, line 17; Form 540NR, line 17; or Form 540 2EZ, line 16 and 
• Any California tax-exempt interest income

Please see Modified adjusted gross income (MAGI) in the 2022 Instructions for Form FTB 3853, available at Forms and publications.
