Washington has no state income tax. All retirement income — Social Security, pensions, 401(k) and IRA withdrawals, and investment income — is completely free from Washington state income tax. Most Washington investors should note that the majority of US states tax capital gains as ordinary income at regular state income tax rates. Federal long-term capital gains tax rates (0%, 15%, or 20%) apply based on your total taxable income.
With a Washington median household income of $82,400, investing just 10% per year ($8,240) at an 8% average annual return could grow to $119,369 in 10 years and $377,079 in 20 years.
