Montana Payroll Tax Registration

As an employer in Montana, it is important to understand the process of payroll tax registration. Registering for payroll taxes with the Montana Department of Revenue ensures compliance with state tax laws and allows you to withhold and remit taxes on behalf of your employees.

How Montana Payroll Registration Works

There are 2 payroll tax setup tasks you may need to complete in Montana to get your new hire on payroll for the first time. You can follow the guide below to help you get registered directly with the Montana agencies or use Mosey to do it.

Montana Unemployment Insurance Setup for LLC, LLP, Corporation

If you have employees in Montana and your total annual payroll equals $1,000 or more, you must register for an Unemployment Insurance tax account with the Department of Labor & Industry. New employers are assigned the average contribution rate of employers classified in their industry. Note: During the registration process, 501(c)(3) organizations will have the choice to either pay unemployment contributions on taxable wages each quarter or elect to reimburse the Montana Unemployment Trust Fund for benefits paid to current or former employees. Organizations who elect the reimbursable payment method are still required to pay the Administrative Fund Tax (AFT) and file quarterly wage reports.

1. Apply for an Unemployment Insurance Account

   Visit the UI eServices for Employers and select "Register a New UI Account" to apply for an Unemployment Insurance Tax account.

2. Create an eServices Online Account
