How can we help?

Find your Montana tax account info

Income tax withholding

Business that have run payroll in Montana before can find their Withholding Account ID on notices received from the Montana Department of Revenue or by contacting the agency directly.

State unemployment

If you've run payroll in Montana previously, you can find your UI Account Number on notices received from the Montana Department of Labor & Industry such as the Welcome Letter, Form UI-5 or by calling the agency at (800) 550-1513. If you have an older UI Account Number that is only 6 digits, you can add a zero to the front of it when adding it to Gusto.

UI Contribution Rate

Do not include the Administrative Fund Tax (AFT) when entering your rate in Gusto.

The UI Contribution Rate can be found on the Welcome Letter or Subjectivity Letter that is received from the Montana Department of Labor & Industry. Click here to view state-by-state UI rates and wage bases. If you’re unsure, verify your rate by calling the agency at (800) 550-1513.
