Comprehensive Guide to California Capital Gains Tax in 2024

California’s capital gains tax rates are among the highest in the nation when combining state and federal taxes. This guide explains how capital gains are taxed in California, key exemptions, and strategies to minimize your tax liability.

How Capital Gains Are Taxed in California

Unlike many states that offer preferential rates for long-term capital gains, California taxes all capital gains as ordinary income. This means:

• Long-term gains (held >1 year) receive no special treatment at the state level
• California doesn’t conform to federal capital gains rates
