Wyoming levies no individual state or local income tax. Your Wyoming state income tax is $0 regardless of filing status or income.

Authoritative Content

Data Source and Methodology

Authoritative source: Wyoming Department of Revenue (DOR) — Official State Website. Reference: “Individual Income Tax (Not Levied in Wyoming).” Last confirmed: 14 September 2025. Direct link: https://dor.wyo.gov/.

All calculations are strictly based on the fact that Wyoming levies no individual state income tax. Therefore, the applied state tax rate is 0% for all filing statuses and income levels.

Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da questa fonte.

The Formula Explained

State tax owed: \( T_{\text{state}} = r_{\text{state}} \times I_{\text{taxable}} \)

For Wyoming: \( r_{\text{state}} = 0 \Rightarrow T_{\text{state}} = 0 \)

Effective state tax rate: \( \text{EffRate} = \begin{cases} \dfrac{T_{\text{state}}}{I_{\text{taxable}}}\times 100\% & \text{if } I_{\text{taxable}} > 0 \\ 0\% & \text{if } I_{\text{taxable}} = 0 \end{cases} \)

Glossary of Variables

Annual income: Your gross yearly earnings before taxes and deductions.
Pre-tax deductions: Amounts like 401(k), HSA, or cafeteria plan contributions typically excluded from taxable income in many jurisdictions.
State taxable income (I_taxable): Income used by a state to compute tax. In Wyoming, the tax rate is 0%, so the output is always $0 regardless.
State tax rate (r_state): The statutory rate applied to taxable income. Wyoming: 0%.
State income tax owed (T_state): The dollar amount of state tax due. Wyoming: always $0.
Effective state tax rate: T_state divided by taxable income, expressed as a percentage. Wyoming: 0%.

How It Works: A Step-by-Step Example

Suppose your annual income is $75,000 and you contribute $5,000 to pre-tax benefits.

  1. Compute state taxable income. For explanatory purposes we use: \( I_{\text{taxable}} = \max(0,\; \text{Income} - \text{PreTax}) = \max(0,\; 75{,}000 - 5{,}000) = 70{,}000 \)
  2. Apply Wyoming’s state rate: \( r_{\text{state}} = 0 \Rightarrow T_{\text{state}} = 0 \times 70{,}000 = 0 \)
  3. Effective state rate: \( \text{EffRate} = \dfrac{0}{70{,}000} \times 100\% = 0\% \)

Result: Wyoming state income tax owed is $0. This remains true for any filing status and income amount under current law.
