State capital gains questions
Do states use the federal long-term capital gains rates?
Usually not. Many states include capital gains in ordinary state taxable income. Washington instead imposes a separate tax on covered long-term gains.
Why does other income affect state tax on a gain?
In progressive-tax states, the gain stacks on top of other taxable income and can enter higher brackets.
Does the calculator include local income tax?
No. NYC and other local taxes, state credits, basis differences, loss limitations and asset-specific exclusions require separate review.
