California is known for having some of the highest state income taxes in the United States. If you live or work in California, understanding how these taxes are calculated is essential for financial planning, budgeting, and avoiding surprises during tax season.
1. Understanding California's Progressive Tax System
California utilizes a progressive income tax system. This means that as your income increases, the percentage of tax you pay on that additional income also increases. You do not pay the highest rate on your entire income; instead, your income is divided into "chunks" or brackets, and each bracket is taxed at its specific rate.
The Franchise Tax Board (FTB) is the state agency responsible for collecting and administering personal income taxes in California.
2. Federal vs. State Income Tax: What's the Difference?
- Federal Income Tax: Collected by the IRS and applies to everyone working in the U.S. It funds national programs like defense, federal highways, and federal agencies.
- State Income Tax (California): Collected by the FTB. This funds state-specific initiatives such as the UC and CSU educational systems, state infrastructure, and local law enforcement grants.
- Standard Deductions: The IRS and California have different standard deduction amounts. For 2026, California's standard deduction is generally lower than the federal standard deduction.
