Compared to other states

On $40,000, the difference between high-tax states (CA, NY, OR, HI) and no-tax states (TX, FL, NV, WA) can be $2,000+/year. Over a 30-year career, that compounds significantly. But cost of living usually offsets — TX no-tax is partially counter-balanced by higher property tax; FL by housing in coastal areas.
