Wyoming state income tax calculator
Wyoming does not levy a state income tax. This confirms your state tax is $0.
How this calculator works
Step 1 starts with the Wyoming taxable income you already calculated on your return. If you are a part-year resident or nonresident, the tool applies the Wyoming income percentage you provide to focus on Wyoming-source income.
Step 2 confirms Wyoming has no state income tax, so the estimated tax remains $0.
Step 3 summarizes the effective and marginal rates so you can see how additional income would be taxed and whether your current estimate matches your expectations.
Frequently asked questions
What income should I enter?
Use Wyoming taxable income from your return. If you only know total income, estimate deductions first or use the standard deduction tool.
Do part-year residents prorate income?
Yes. Use the Wyoming income allocation percentage from your return to prorate taxable income, but the state tax remains $0 because Wyoming does not levy income tax.
Does Wyoming have income tax brackets?
No. Wyoming does not have a personal income tax, so there are no brackets by filing status.
Is this tax advice?
No. This tool provides estimates based on the inputs you provide and is not legal or tax advice.
