Key Components of California Income Tax Calculation

1. Taxable Income Determination

   Your California taxable income starts with your federal adjusted gross income (AGI) and then applies specific California modifications. Common adjustments include:

   • Adding back certain federal deductions not allowed by California
   • Subtracting income exempt from California tax (like some municipal bond interest)
   • Adjusting for California-specific deductions
2. Standard Deduction vs. Itemized Deductions

   For 2020, California’s standard deduction amounts were:

   • Single/Married Filing Separately: $4,537
   • Married Filing Jointly/Qualifying Widow(er): $9,074
   • Head of Household: $9,074

   Taxpayers could choose between the standard deduction or itemizing deductions, whichever provided greater tax benefit.

3. Personal Exemptions

   California allowed personal exemptions of $122 per exemption for 2020. However, these were phased out for higher-income taxpayers:

   • Single: Phase-out begins at $264,615
   • Married Filing Jointly: Phase-out begins at $317,538
   • Head of Household: Phase-out begins at $317,538
4. Alternative Minimum Tax (AMT)

   California has its own AMT system with rates of 7% or 9.3% (depending on income level) and exemption amounts that differ from federal AMT.
