Taxes in Irvine
California levies a real, current top marginal state income tax of 13.3% -- the highest of any US state, including a 1% Mental Health Services Act surcharge on income over $1M -- atop an underlying nine-bracket structure running 1%-12.3%, meaning Irvine's genuinely high-earning population carries a real, significant, and never-flattened state tax burden.

Learn moreCalifornia's Real, Highest-in-the-Nation Top Marginal Income Tax
California's top marginal state income tax rate is 13.3% for 2026 -- the highest of any US state -- comprising a nine-bracket structure running 1%-12.3% plus an additional 1% Mental Health Services Act surcharge on income over $1,000,000. This is a real, meaningful cost that a mover comparing Irvine against a lower- or no-income-tax state should budget for directly, not assume away, and this record states it precisely per this build's explicit instruction rather than citing only the lower 12.3% base-bracket figure.
Property Tax Runs Through Prop 13, With a Real Irvine-Specific Complication
As detailed in full on the property-taxes topic page, California's Proposition 13 caps assessed-value growth at roughly 2%/year until resale, and Orange County's effective rate carries a real, disclosed spread (0.66%-1.3% depending on methodology) -- with many newer Irvine developments carrying additional Mello-Roos special assessments beyond that base figure.
Irvine's Combined Sales Tax Runs 7.75% Within City Limits
California's state sales tax rate is 6%, but Irvine's actual combined rate runs 7.75% within the incorporated city limits once Orange County's 0.25% and a 1.5% special district rate are layered in. Confirm the current combined rate for a specific address, since it can differ just outside the city line.
No Special State-Level Capital Gains Treatment
California taxes capital gains as ordinary income under its progressive income-tax structure (up to the same 13.3% top marginal rate), rather than through a separate, lower capital-gains rate the way federal tax law does -- a genuinely significant consideration for equity-compensated tech and biotech employees relocating to Irvine specifically, given the concentration of stock-compensated roles at employers like Broadcom's Irvine R&D campus and the broader Orange County tech sector.
