New Hampshire Payroll Setup in 2026: What LLC Owners Must Do Before the First Check

August 19, 2026

Your New Hampshire LLC has a formation certificate and an annual report on file. Now someone is starting work and the clock on payroll compliance starts ticking the moment they walk in the door. New Hampshire makes some things easier than other states — there is no state income tax, which simplifies one withholding obligation right away. But the state still has its own payroll requirements that are separate from anything the Secretary of State knows about.

This guide covers every registration your New Hampshire LLC needs to complete before the first paycheck. Each step has a deadline. Missing them costs money.

Why New Hampshire Has Its Own Payroll Rules

Your LLC formation with the New Hampshire Secretary of State tells the state your business exists. It does not tell the New Hampshire Employment Security Department that you are about to become an employer. It does not tell the IRS. It does not set up your ability to withhold federal taxes from employee wages. All of those are separate processes with separate portals and separate deadlines.

New Hampshire is one of the few states with no personal income tax. That sounds like a win for employees, and it is. It means you are not deducting New Hampshire state income tax from paychecks. Do not let that convince you that payroll setup is simple. New Hampshire still requires employer registrations for unemployment insurance, Business Enterprise Tax, new hire reporting, and workers compensation coverage. Each one has a filing frequency, a penalty structure, and an agency that expects you to know the rules.

Step 1: Get Your Federal Employer Identification Number

Before you do anything else, you need a Federal Employer Identification Number from the IRS. This is the nine-digit number that identifies your LLC for all federal payroll tax purposes. If your LLC already has an EIN because you opened a bank account or signed contracts, use that same number. You do not get a new one for payroll.

If you do not yet have an EIN, apply at irs.gov. The online form takes about five minutes and the IRS issues the number immediately during business hours. There is no filing fee. Print the confirmation and keep it somewhere safe — every agency on this list will ask for it.

Do not use your personal Social Security number for payroll. Do not wait until the first payday to get this done. Running payroll without a proper EIN triggers federal penalties that accumulate fast.

Step 2: Register with New Hampshire Employment Security for Unemployment Insurance

New Hampshire operates an unemployment insurance program through N.H. Employment Security. As a New Hampshire employer, you pay unemployment tax on the first $14,400 in wages paid to each employee in 2026. This is called the taxable wage base. Once an employee earns more than that in a calendar year, you stop paying unemployment tax on their wages for the rest of that year.

New employers in New Hampshire pay a standard rate of 1.7 percent on the taxable wage base for the first 36 months. This means the maximum unemployment tax per employee in a year is currently $244.80. If you hire three employees earning above the wage base, your annual unemployment tax would be around $734.

You must register with N.H. Employment Security before your first payroll. Create an employer account through the N.H. ES portal at nhes.nh.gov. The registration is free. Once registered, you will file quarterly wage reports and pay unemployment taxes on a quarterly schedule.

One thing to watch: if you have employees working in multiple states, New Hampshire unemployment tax applies only to wages for work performed in New Hampshire. If your employees are remote and live in other states, you may need to register with those states too. Talk to a CPA before assuming New Hampshire is your only unemployment tax obligation.

Step 3: Register for the New Hampshire Business Enterprise Tax

The New Hampshire Business Enterprise Tax is one of the more unusual features of doing business in the state. It is a tax on the portion of your business that represents compensation paid to officers, shareholders, and certain relatives. If your LLC pays out more than $200,000 in combined compensation to these parties in a tax year, you owe Business Enterprise Tax.

This is not a payroll tax in the traditional sense. It is measured on what the state calls the “taxable enterprise value” — essentially, compensation paid to the people who own and run the business. If you are the sole member of your LLC and you pay yourself a salary, the Business Enterprise Tax applies to that compensation once it exceeds the $200,000 threshold.

Register for the Business Enterprise Tax through the New Hampshire Department of Revenue Administration at revenue.nh.gov. File using the BET-80 return, which is due annually but requires quarterly estimated payments if your liability exceeds $500 per year. The rate is 0.6 percent on the taxable enterprise value.

Even if you are far below the $200,000 threshold, you still need to register and file the annual BET-80 return. Failing to register and file when you were below the threshold is a common audit trigger. Register from day one and file a zero return if nothing is owed.

Step 4: Handle New Hampshire New Hire Reporting

Federal and New Hampshire law require every employer to report newly hired employees to the N.H. Division of Unemployment Security within 10 days of their start date. This is faster than most states — many give you 20 days. Ten days is the deadline in New Hampshire, so build that into your onboarding timeline.

New hire reporting requires the employee’s full name, address, Social Security number, and start date. You also need to report certain contractors if you pay them $2,500 or more in a calendar quarter. The reporting portal is the same N.H. ES system where you registered for unemployment insurance.

New hire data goes into the National Directory of New Hires, which state agencies use to enforce child support orders and detect unemployment benefit fraud. The federal penalty for willful non-reporting can run $25 per employee for the first violation and $500 for subsequent violations.

Step 5: Set Up Federal Payroll Tax Withholding

Even though New Hampshire has no state income tax, federal income tax withholding still applies to every paycheck. You are required to withhold Social Security and Medicare from employee wages under FICA — the Federal Insurance Contributions Act.

The employee Social Security rate is 6.2 percent on wages up to $168,600 in 2026. Medicare is 1.45 percent on all wages with no cap. As the employer, you also pay a matching 7.65 percent in FICA taxes on behalf of each employee.

You also withhold federal income tax using the W-4 form each employee fills out at hiring. The IRS publishes withholding tables in Publication 15-T that tell you exactly how much to withhold based on the employee’s filing status, pay frequency, and claimed allowances. The tables update annually and sometimes mid-year — always use the current version.

For most small New Hampshire LLCs, running payroll by hand using Publication 15-T is possible for one or two employees on a monthly schedule. For anything more than that, use a payroll service like Gusto, ADP, or Paychex. The monthly fee — typically $20 to $60 — is far less than the cost of a missed Form 941 filing, which carries a penalty of $470 per month per unfiled quarter.

Step 6: Understand New Hampshire Workers Compensation Requirements

New Hampshire law requires virtually all private employers to carry workers compensation insurance once they have employees. This is not optional and it is not a payroll tax — it is a commercial insurance policy that covers medical expenses and lost wages when an employee is injured on the job.

The exceptions are very narrow. If your business is purely agricultural with fewer than six employees, or if you are a sole proprietor with no employees, you may be exempt. Every LLC with even one W-2 employee should carry coverage unless it falls into one of the narrow statutory exemptions.

Workers compensation premiums in New Hampshire are based on your payroll, the classification codes for the work your employees do, and your claims history. A small New Hampshire LLC with clerical office staff can often obtain coverage for $400 to $800 per year. A business with employees doing physical labor — construction, manufacturing, delivery — will pay significantly more.

Get at least two quotes from carriers authorized to write workers comp in New Hampshire. You can find the state-approved workers comp carrier list through the New Hampshire Insurance Department. Do not operate without this coverage. A single workplace injury resulting in a surgery can generate a $100,000-plus medical lien against your business if you are uninsured.

Step 7: New Hampshire Payday Rules and Employee Classifications

New Hampshire has specific rules about how often you must pay employees. The state Payday Law requires most employers to pay employees at least semimonthly — meaning you must issue paychecks at least twice per month. You can pay weekly, biweekly, or semimonthly. You cannot pay monthly.

If you plan to use independent contractors instead of employees, New Hampshire follows the federal standard for independent contractor classification under the ABC test. The worker must be free from control and direction, perform work outside the usual course of the business, and customarily be engaged in an independently established trade or occupation. Misclassifying an employee as a contractor to avoid payroll taxes is one of the most expensive mistakes a New Hampshire LLC can make. The IRS, N.H. ES, and the NH Department of Labor can all assess back taxes, penalties, and interest.

Before classifying a worker as a contractor, run them through the federal and state classification tests. If the relationship looks like employment — set hours, company equipment, training by you, ongoing relationship — the contractor designation is probably wrong.

Step 8: Set Up Your Payroll Process

With all the registrations complete, you need a reliable system for running payroll going forward. The three realistic options for a small New Hampshire LLC are manual processing, a payroll service, or having your accountant handle it.

Manual processing using IRS Publication 15 and Publication 15-A is manageable if you have one or two employees and pay on a consistent monthly or semimonthly schedule. The math is straightforward for New Hampshire since there is no state income tax withholding — you only calculate federal income tax, Social Security, and Medicare. The risk is human error in the withholding tables, missed quarterly Form 941 filings, and missed N.H. ES quarterly wage reports.

A payroll service handles everything automatically — the calculations, the filings, the tax payments — for a monthly subscription. Gusto, ADP, and Paychex all support New Hampshire payroll with the correct state filings. For a small LLC paying two or three employees, the cost is typically $25 to $60 per month.

Your CPA or bookkeeper can also run payroll as part of your monthly accounting engagement. This is often the smoothest option if you already have a financial professional, because payroll data flows into your financial statements and your annual tax filings without a separate import step.

What Happens If You Miss a Registration

Running payroll without the proper New Hampshire registrations triggers a cascade of penalties. If you pay employees without an EIN, the IRS cannot match your tax deposits to your account and will assess penalties plus interest from the due date of the first missed deposit.

If you fail to register with N.H. Employment Security for unemployment insurance, the state can assess back taxes going back up to four years, including interest and a 10 percent penalty on the unpaid amount. Willful failure to register can double the penalty.

For the Business Enterprise Tax, the NH Department of Revenue can assess back taxes, interest, and penalties going back seven years if you failed to file. Even if you owed nothing because you were below the $200,000 threshold, failing to file the BET-80 return when required creates compliance issues that a CPA will have to clean up.

Operating without required workers compensation coverage exposes your LLC’s bank account and assets to personal injury claims from employees. New Hampshire courts routinely enter judgment against uninsured employers for the full amount of an injured worker’s damages.

Timeline: How Long Does New Hampshire Payroll Setup Take?

Here is the realistic timeline for completing New Hampshire employer registrations before the first payroll:

• EIN from the IRS: Immediate online (same day, during IRS business hours)
• N.H. Employment Security unemployment insurance registration: One to three business days, online
• Business Enterprise Tax registration with NH DRA: Three to five business days, online
• New hire reporting: Ongoing, within 10 days of each new hire’s start date
• Workers compensation insurance: One to five business days to get quotes and bind coverage
• Federal payroll tax setup: Same day as EIN if using a payroll service

Most businesses complete the core registrations in one to two weeks when working on them concurrently. Start the process at least two weeks before the employee’s first scheduled start date.
