Montana First Employee Checklist in 2026: State Payroll Setup for New LLCs

August 18, 2026

Most Montana LLC owners hiring their first Montana first employee do not know the state requires several registrations before the first paycheck goes out. The federal side is familiar to most people. The Montana state side catches new business owners off guard. This checklist covers every required step so the LLC is compliant before the first wages are paid.

Why Montana Payroll Registration Cannot Wait Until Payday

Montana treats payroll registration as a precondition for paying wages, not something to handle after the fact. The state requires separate registrations for unemployment insurance, new hire reporting, and state income tax withholding. Each one has its own deadline. Missing them results in penalties that are entirely avoidable. The good news is that Montana has consolidated many of these filings into the Montana Department of Labor and Industry online system. Setting everything up takes a few hours on a Saturday morning if the owner knows what to look for. This article breaks down each step.

Register for Montana Unemployment Insurance

Every employer in Montana must register for unemployment insurance with the Montana Department of Labor and Industry if they have one or more employees. This applies even if the employee is part-time or a family member. The registration is done through the Montana Business Hub at mbi.mt.gov. The LLC will receive a Montana UI account number once the registration is processed. The quarterly wage report is filed through the same system. The UI tax rate for new employers starts at a predetermined rate that adjusts based on the LLC’s payroll and benefit claim history over time. Paying on time and filing accurate quarterly reports keeps the rate predictable as the business grows. Montana UI funds go toward benefits for workers who lose their jobs through no fault of their own. The registration is not optional and the quarterly filings are due even in months when no wages are paid.

Report the New Hire to the State

Montana requires every employer to report newly hired employees to the Montana New Hire Reporting Center within 10 days of the start of work. This is a federal requirement that every state administers, but Montana enforces it actively and matches the reports against child support orders and other obligations. The report can be filed online through the Montana Department of Labor and Industry website. The information reported includes the employee’s name, Social Security number, address, start date, and the LLC’s Montana employer account number. Filing the new hire report on or before the employee’s start date keeps the LLC in compliance. The 10-day window is a deadline, not a target. Reporting early is better than waiting until day nine.

Set Up State Income Tax Withholding

Montana requires employers to withhold state income tax from employee wages. Before the first paycheck goes out, the LLC must register for withholding with the Montana Department of Revenue. The registration is available through the Montana Department of Revenue online portal. The LLC will receive a withholding account number that must be included on every payroll filing. State withholding filings in Montana are submitted on a quarterly basis along with the federal Form 941. The filing deadlines are the same as federal: April 30, July 31, October 31, and January 31. Missing these deadlines triggers penalties from the Montana Department of Revenue. The LLC does not need to calculate the withholding amount from scratch. The Montana Department of Revenue provides withholding tables that align with the state’s income tax brackets.

Obtain Workers Compensation Insurance

Montana requires most employers to carry workers compensation insurance. This is not optional. If an employee is injured on the job, workers comp covers medical costs and a portion of lost wages. Without it, the LLC is exposed to significant liability. Montana has a state fund workers compensation program operated by the Montana State Fund. Private insurers also offer workers comp policies in Montana. Either option satisfies the state requirement. The policy must be in place before the first day of work. Some business owners wait until an injury happens to get coverage. By then it is too late — the injury is not covered retroactively. LLCs with very low payroll may qualify for a minimum premium policy. Talking to an agent about the specific employee duties helps determine the correct classification code and premium estimate.

Verify Employee Eligibility to Work

Before the first paycheck, the LLC must verify that every new employee is legally authorized to work in the United States. This is done by completing Form I-9 for each employee within three days of the start of work. The form requires the employee to present documents that establish identity and employment authorization, such as a US passport or a combination of a state driver’s license and a Social Security card. The LLC reviews the documents in person and records the information on the form. Keeping I-9 forms on file for every employee is required. These forms do not get filed with any government agency but must be available if the LLC is ever audited by US Citizenship and Immigration Services or the Department of Labor.

Set Up a Payroll System or Payroll Service

Montana has no state minimum wage separate from the federal minimum wage. As of 2026, the federal minimum wage of $7.25 per hour applies. If the LLC pays tipped employees, a lower tipped wage rate is permitted under federal law, but the employer must ensure tips plus the tipped wage meet or exceed the federal minimum. Regardless of how simple the first payroll seems, using a payroll service or software from the start prevents errors in tax withholding calculations and ensures the LLC meets federal and state filing deadlines automatically. Popular payroll software options integrate with Montana unemployment insurance and withholding filings. The cost of a payroll service is far less than the cost of an IRS or Montana Department of Revenue penalty for a missed filing.

Federal Registrations That Run Parallel

While the focus here is Montana state requirements, the federal side must not be forgotten. The LLC needs an EIN from the IRS before hiring. If the LLC has a retirement plan for employees, an ERISA registration may eventually be needed. A new LLC hiring its first employee also needs to register for federal payroll taxes by filing Form 941 quarterly. The EIN application is completed online at irs.gov in minutes. It is free and immediate. There is no reason to delay this step. Completing the Montana first employee checklist before the start date means the LLC is ready to run payroll correctly from paycheck one.
