Montana First Employee in 2026: Payroll and New-Hire Steps LLC Owners Need in Order

August 22, 2026

Montana first employee in 2026 is a moment most LLC owners have been building toward for months. You filed your articles of organization, set up your EIN, maybe got your first real customer. Then you decided it was time to stop doing everything yourself. Hiring feels like a milestone. The payroll side of it does not have to feel like a mystery. There is a specific order to the steps, and getting that order right is what keeps the first payroll clean and the LLC in compliance with every agency that matters.

Step One: Federal EIN — Before Anything Else Touches Payroll

Your Employer Identification Number from the IRS is the master key. Every payroll tax account — federal and state — asks for it. You cannot register with the Montana Department of Labor and Industry, the Montana Department of Revenue, or file a single federal payroll tax form without it.

If your LLC does not already have an EIN from your formation, apply at IRS.gov right now. The online application takes five minutes and the number is issued on the spot, Monday through Friday, 7 a.m. to 10 p.m. Eastern. There is no filing fee. Write the number down and keep it accessible — you will need it for every remaining step on this list.

If your LLC was formed as a new business entity, you need a fresh EIN even if you previously operated as a sole proprietorship under your Social Security Number. The entity change resets your federal tax identity.

Step Two: Register With Montana Before the First Paycheck

Two Montana agencies need to know you are hiring before you cut that first check. Register with both at the same time — they do not depend on each other, but both need to be done before payroll runs.

Montana Department of Labor and Industry — UI Division

Register for your Montana unemployment insurance employer account through the Montana DLI UI Division. This account establishes your UI tax rate and puts you on the schedule for quarterly wage reporting. New employers in Montana pay a contribution rate set at the time of registration, and the rate adjusts after you have enough experience history to be rated.

The new employer UI rate in Montana for 2026 ranges from approximately 1.0 to 2.1 percent of each employee’s wages up to the Montana taxable wage base of $47,300 per employee per year. That wage base — the maximum taxable earnings per worker — is updated each January based on the prior year’s average annual wage in the state. Tracking it annually matters because employees who earn above the wage base in one year fall out of the UI tax calculation for the remainder of that year, then re-enter in the next calendar year.

Montana Department of Revenue — Withholding Tax Account

If your employee will earn wages subject to Montana income tax, you also need a withholding tax account with the Montana Department of Revenue. This account is where you register to withhold Montana income tax from employee wages and remit those withholdings on the schedule assigned to your account.

Montana uses a flat withholding rate for most employees — the rate does not vary by bracket because Montana’s individual income tax system uses a two-bracket structure effective in 2026 under HB 337. The rate is 4.7 percent on income up to $47,500 for single filers, or $95,000 for married filing jointly. Income above those thresholds is taxed at 5.65 percent. Most employees earning wages below those thresholds will have withholding calculated at the 4.7 percent rate. The DOR publishes withholding tables that account for this in the TAP portal.

Register for both accounts before the first payroll date. Montana assigns your deposit schedule — monthly or quarterly — based on the size of your payroll once you register.

Step Three: Collect I-9, W-4, and the Montana Equivalent Before Day One

Federal law requires you to have a completed Form I-9, Employment Eligibility Verification, on file for every employee within three business days of their start date. This is not a filing — you keep it. The government does not receive a copy unless they ask for it during an audit. But the requirement to have it is absolute.

Section 1 of the I-9 is completed by the employee on or before their start date. Section 2 is completed by you, the employer, within three business days. You must physically examine the documents the employee presents to establish identity and work authorization — a remote or electronic examination is not permissible under current guidance unless you used an E-Verify employer-authorized alternative.

Form W-4, the Employee’s Withholding Certificate, determines how much federal income tax you withhold from each paycheck. The updated 2020 W-4 form eliminated the allowance system — employees now fill out a step-based worksheet covering multiple jobs, spousal income, and claimed dependents. Walk your employee through it on their first day. The more accurate the W-4, the less surprise your employee gets at tax filing time.

For Montana state withholding, employees complete the Montana Employee’s Withholding Allowance Exemption Certificate — essentially the state equivalent of the W-4. Both forms should be completed and signed before the first paycheck runs. Without them, you have no legal basis to withhold anything and you may end up remitting too much or too little.

The Montana Payroll Guide has step-by-step instructions for each form if you need a reference to share with your employee or walk through yourself.

Step Four: Report Your New Hire Within 20 Days

Montana requires every employer to report newly hired employees to the state New Hire Reporting Center within 20 calendar days of their start date. This applies to every hire — full-time, part-time, temporary, and seasonal. The report goes to mt-newhire.com and the information is used for child support enforcement and unemployment insurance fraud detection.

The report itself is brief: employee name, address, and Social Security Number, plus your EIN, the hire date, and the payroll frequency. Most payroll software handles this automatically. If you are running payroll manually, set a calendar reminder for it — the 20-day window is a real compliance deadline and late reporting can result in penalties.

This step costs nothing and takes five minutes. There is no reason to miss it.

Step Five: Federal Payroll Taxes on That First Paycheck

Every payroll run triggers federal employer taxes. These are not withholding from the employee — they are costs you pay as the employer, on top of the wages you owe.

Social Security and Medicare — FICA

You pay 6.2 percent of each employee’s wages up to the Social Security wage base of $184,500 for 2026. You also pay 1.45 percent on every dollar of earnings for Medicare, with no wage cap. If an employee’s wages exceed $200,000 in a calendar year, you pay an additional 0.9 percent Medicare tax on the excess — this one has no wage base ceiling.

FICA is split: the employee pays the other half through withholding. Your employer share is 7.65 percent of wages up to the Social Security cap, then 2.35 percent on everything above $200,000. These numbers matter because they are a direct payroll cost, not a withholding.

Federal Unemployment Tax — FUTA

FUTA is 6.0 percent on the first $7,000 of each employee’s wages. If you are also paying Montana UI contributions on time throughout the year, you receive a credit of up to 5.4 percent, bringing the effective federal rate to 0.6 percent on the first $7,000 per employee. That is $42 per employee at the maximum.

FUTA is filed annually using Form 940. Even if you qualify for the credit, you still file the form to claim it. Montana employers who are current on their state UI payments typically qualify for the full credit.

The IRS Employer’s Tax Guide covers federal payroll tax obligations in detail, including which forms to file, when to deposit, and how to handle tricky situations like employees who reach the wage base mid-year.

Step Six: Run Your First Payroll

With all accounts in place, the first payroll itself is straightforward. The critical thing at this stage is choosing your payroll frequency and sticking to it.

Montana has no state law mandating a specific payroll frequency for most private employers, but most small businesses use biweekly (26 pay periods per year) or semimonthly (24 pay periods). Your frequency affects how you calculate overtime — overtime is required for any hours worked over 40 in a seven-day workweek under the federal Fair Labor Standards Act, and the calculation resets every week. Montana has no state overtime law that differs from the federal standard.

If you are doing payroll manually for the first pay period, use a reputable payroll calculator or your accounting software. Do not estimate tax withholdings by hand. The penalties for incorrect withholding — underpaying the IRS or the Montana DOR — are easier to avoid than to fix after the fact.

If your employee is salaried and exempt from overtime under the FLSA, the rules are different. Misclassifying an hourly nonexempt employee as exempt to avoid overtime is one of the most common and costly payroll mistakes small businesses make. If you are unsure about the classification, this is worth a short conversation with an employment attorney before the first payroll runs.

Step Seven: Ongoing Filing Calendar for the Rest of the Year

After the first payroll, the ongoing compliance calendar takes over. For a Montana LLC with one employee, the main recurring deadlines are:

Federal Form 941 — filed quarterly, due by the last day of the month following each quarter (April 30, July 31, October 31, January 31). This reports federal income tax withheld, Social Security, and Medicare for the quarter. Deposit federal withholdings monthly or semiweekly depending on your payroll amount.
Montana UI quarterly wage report — filed quarterly, due by the last day of the month following each quarter. The same deadline as the federal Form 941. Your UI tax payment may be submitted separately or combined depending on how DLI assigns your account.
Form 940 — filed annually, due January 31 (or February 10 if you deposited FUTA on time and in full throughout the year). This reconciles your annual FUTA tax liability.
Montana annual withholding reconciliation — due annually, typically filed with your employee’s W-2 forms by January 31. The state copy of the W-2 goes to the Montana DOR.
New hire reports — within 20 days of every new hire, including rehires after a 60-day break in employment.
Form I-9 retention — keep completed I-9 forms for three years after the hire date or one year after the employee leaves, whichever is later. Store them somewhere accessible — an IRS or DLI audit will ask for them.

The key to staying current is not trying to memorize everything at once. Set recurring calendar reminders for each quarterly and annual deadline before you run your first payroll. It takes five minutes and saves the panic of a missed filing.

Step Eight: What You Do Not Have to Worry About in Montana

One thing that makes Montana employer payroll simpler than most states: there is no state disability insurance, no state paid family leave program, and no state-mandated supplemental pay beyond what federal law requires. Some states add their own layers on top of FICA — California has SDI, Washington has Cares Act remnants, several states have Polonia-type programs. Montana has none of those at the state level.

Montana also has no local income taxes. Cities like Bozeman, Missoula, and Billings do not assess their own income taxes. The only state-level tax you are withholding is the flat Montana individual income tax rate, which simplifies your payroll calculations compared to states where employees live in different cities or counties with their own withholding schedules.

What you still need from day one: workers’ compensation insurance. Montana requires it from the first day of the first employee’s work. That is separate from payroll tax but it is an absolute requirement tied to the same hiring event. Your payroll service or accountant will ask about it, and if you do not have a policy, get one before the first check runs. When your Montana first employee in 2026 is finally on payroll and all the accounts are filed, the compliance calendar for the rest of the year is mostly automatic — quarterly Form 941, quarterly Montana UI, annual Form 940, and the annual W-2 reconciliation. Get those eight steps right and your LLC stays clean with every agency that matters.
