The following diagnostic is generating:
Taxpayers with adjusted gross income equal or greater than $1,000,000 (or $500,000 for married/RDP filing separately) must use estimate option 1 (100% of {NextTaxYear} tax) or 3 (90% of {NextTaxYear} tax) to avoid underpayment penalty in {NextTaxYear}.
Solution:
Informational diagnostic California Form 5805 Page 2 Part II has you use 90% of that year's tax to figure the underpayment penalty when California AGI is equal to or greater than $1,000,000/$500,000 for married/RDP filing a separate return. Other methods may result in higher estimated tax payments being made depending on the situation.
