Common Deductions and Credits

Several deductions and credits can reduce your taxable income or lower your tax bill:

  • Standard Deduction: A fixed amount that reduces your taxable income.
  • Itemized Deductions: Expenses like mortgage interest, charitable donations, and medical expenses that can be deducted if they exceed the standard deduction.
  • Earned Income Tax Credit (EITC): A refundable credit for low- to moderate-income workers.
  • Child Tax Credit: A credit for each qualifying child under age 17.

Taxable Income = Gross Income - Deductions

Example Calculation

Let's calculate taxes for a single filer in California with $75,000 gross income:

  1. Federal taxable income: $75,000 - $13,850 (standard deduction) = $61,150
  2. Federal tax:
    • $10,275 × 10% = $1,027.50
    • ($41,775 - $10,275) × 12% = $3,741.60
    • ($61,150 - $41,775) × 22% = $4,355.90
    • Total federal tax = $1,027.50 + $3,741.60 + $4,355.90 = $9,125.00
  3. California state tax: $61,150 × 12.3% = $7,542.15
  4. Total estimated taxes: $9,125.00 + $7,542.15 = $16,667.15

This example shows that the combined federal and state taxes would be about 22.2% of gross income in this scenario.
