State capital gains tax: zero, flat, and high-tax states

Updated 2026-08-18 · Educational only — not tax advice

Federal capital gains tax is only part of the story. States fall into rough buckets: zero state income tax on capital gains, flat-rate taxation, graduated ordinary-income treatment, and a handful of special-rule jurisdictions.

Zero-tax examples include Texas and Florida. Flat-rate states such as Illinois apply a single percentage in our model. Graduated states like California can push combined federal-plus-state effective rates well above 30% for top earners. Washington, North Dakota, and Montana apply specialised capital gains rules that are not a simple flat percentage.
