Updated October 4, 2026. Quick answer: No. Wyoming does not tax 401(k) or IRA withdrawals: its statutes impose no individual income tax. Title 39’s chapter on income taxes holds one section, and the compiled statutes print “39-7-101. Repealed By Laws 1998, ch. 5, § 4”. Federal tax on the withdrawal still applies.

What Wyoming does with 401(k) and IRA withdrawals
The statutes reserve the field to the state: “any other form of tax based on wages or other income”. The statutes do not say in so many words that Wyoming has no income tax, and no Department of Revenue page stating it could be read for this page, so the answer rests on the absence of any individual income tax in Title 39.
