529 Plan Deductions in California
A 529 plan is a tax-advantaged savings account designed to help families pay for education expenses, including college tuition, K-12 tuition up to certain limits, and apprenticeship program costs. Contributions grow tax-free at the federal level, and qualified withdrawals are not subject to federal income tax.
California does not allow a state income tax deduction for contributions made to any 529 plan, including its own ScholarShare 529 program. This makes California one of the few large states that offers no upfront state tax benefit for 529 contributions, so the primary advantage for California residents is federal tax-free growth and withdrawals.
Despite the lack of a state deduction, California families still benefit from the federal tax-free compounding within a 529 account. Residents should be aware that non-qualified withdrawals are subject to both federal income tax and a 10 percent penalty on earnings, and California also imposes its own 2.5 percent additional tax on non-qualified distributions.
