Wyoming Tax Overview
Wyoming levies no state income tax on wages, putting it among 9 states that leave that portion of the tax burden entirely to the federal government. That makes WY especially attractive to high earners — a $150,000 salary keeps roughly $8,000 more annually than a comparable earner in a 5% flat-rate state. No local income taxes apply in most jurisdictions.
