How State Taxes Are Calculated
Understanding the process:
Step 1: Start with Federal AGI
Most states: Start with your federal Adjusted Gross Income (AGI)
Why: Simplifies calculation, uses federal numbers
Step 2: Apply State Adjustments
States may:
- Add back certain deductions
- Subtract state-specific deductions
- Make other adjustments
Varies by state: Each state has different adjustments
Step 3: Calculate State Taxable Income
Formula: Federal AGI + State adjustments - State deductions = State taxable income
State deductions: May be different from federal (often lower)
Step 4: Apply State Tax Brackets
Use state brackets to calculate tax
Rates: Vary by state (flat or progressive)
Real Calculation Example
Scenario: $80,000 net income, California
Federal AGI: $80,000 CA standard deduction: -$5,202 (single) CA taxable income: $74,798 CA tax (progressive): ~$4,500
Compare to Texas (no state income tax):
- State tax: $0
- Savings: $4,500 (by living in Texas vs. California)
