Understanding Each State
California
California has the highest top marginal state tax rate in the US at 13.3%, with progressive brackets starting at 1%. An additional 1% Mental Health Services Tax applies to incomes over $1 million. Despite high taxes, California's economy — tech, entertainment, agriculture — attracts top talent globally. Under OBBBA (2025+), the SALT deduction cap rose to $40,000 ($20,000 MFS) but phases out $1-for-$1 above $500,000 MAGI ($250,000 MFS) toward a $10,000 floor — so high-income California itemizers see only partial federal relief.

Washington
Washington has no state income tax but imposes a 7% capital gains tax on gains exceeding $270,000 (effective 2023). The state relies on a relatively high sales tax (6.5% state + local, often totalling 10%+). Washington is a major tech hub (Seattle), attracting high earners who benefit from the lack of income tax.
Tip: If you have significant investment income, note that Washington's capital gains tax may apply to gains above $270,000. For salary-only earners, Washington remains one of the most tax-efficient states.
