Updated October 5, 2026. Quick answer: No. Wyoming has no individual income tax, so there is nothing to tax an HSA contribution under. The Wyoming Legislature’s Legislative Service Office lists the “Individual Income Tax 0% (Note Art. 15, Sec. 18)” in its tax rates table. The 2026 federal HSA limits are $4,400 for self-only coverage and $8,750 for family coverage.

What the Wyoming documents say
The Legislative Service Office’s June 2025 table of Wyoming tax rates and collections lists the individual income tax with a base rate of zero: “Individual Income Tax 0% (Note Art. 15, Sec. 18)”. The Legislative Service Office’s 2021 comparison of Wyoming’s tax structure to other states has a line for “No Individual Income Taxes”.
Earnings, distributions and the rest
The documents read do not mention HSAs, and they are from the Legislature’s own staff office; the Department of Revenue pages archived for this page did not state the point themselves. The conclusion that Wyoming does not tax HSA contributions, earnings or distributions follows from the absence of an individual income tax, not from an HSA rule. Federal rules still decide whether a contribution is excluded or deductible and whether a nonqualified distribution is taxed or penalized.
A worked example at the 2026 family limit
An illustration: a Wyoming resident with family coverage who contributes the 2026 federal family limit of $8,750 owes $0 of Wyoming individual income tax on it, because the state imposes none. The federal limit for self-only coverage is $4,400, so the family contribution is $4,350 larger.
What a mover should know
Every figure on this page is Wyoming’s own rule. If you moved during the year, or live in one state and work in another, check each state’s page and return, because the documents read here describe only Wyoming and none of them settles a part-year or two-state case. The federal side is the same everywhere: see CMG’s 2026 HSA contribution limits page, and state tax on HSA contributions for the other states checked.
What the documents do not say
- No Wyoming document read mentions health savings accounts by name; the answer is the absence of the tax, not an HSA-specific rule. The sources are Legislative Service Office documents rather than a Department of Revenue statement.
Common mistakes
- Assuming the federal rules disappear along with the state tax; the federal limits and the nonqualified-distribution rules still apply to a Wyoming resident.
- Assuming the answer for one state applies to another, or that the state answer changes the federal limits.
