What Is New Hampshire Payroll Tax?
New Hampshire payroll tax refers to the state unemployment insurance tax that employers pay to New Hampshire Employment Security (NHES). This tax helps fund unemployment benefits for eligible workers who lose their jobs through no fault of their own.
New Hampshire is one of nine states with no state tax on earned wages, and as of January 1, 2025 it has no state-level income tax of any kind. The state historically taxed interest and dividend income separately from wages, but that Interest and Dividends Tax was fully phased out effective January 1, 2025. New Hampshire also has no state disability insurance program, no employment training tax, and no local income tax anywhere in the state, making it one of the simplest states in the country for payroll tax compliance.
Most New Hampshire employers are responsible for one primary state payroll tax requirement:
- Unemployment Insurance (UI), also called State Unemployment Tax (SUI), administered by New Hampshire Employment Security
Because New Hampshire has no state income tax of any kind, employers do not withhold any state income tax from employee wages payroll here centers almost entirely on UI, plus standard federal payroll tax obligations.

New Hampshire Employer Payroll Tax Responsibilities
Every employer with workers in New Hampshire has payroll tax responsibilities beyond simply issuing paychecks. Depending on your business, you'll generally need to:
- Register your business with New Hampshire Employment Security.
- Determine whether your business has met the wage or employment threshold that makes you liable for UI.
- Calculate taxable wages up to the annual UI wage base.
- Pay employer UI contributions.
- File quarterly wage reports, even in quarters with no wages paid.
- Comply with New Hampshire's weekly pay-frequency requirement a rule that catches many employers relocating from states with monthly or semi-monthly pay schedules off guard.
- Maintain payroll records for state compliance.
Many businesses automate these tasks using payroll software, reducing the risk of manual errors and missed deadlines.
Understanding New Hampshire Unemployment Insurance (UI)
Unemployment Insurance is an employer-funded payroll tax that provides temporary financial assistance to eligible workers who lose their jobs through no fault of their own. In New Hampshire, it is the only state-level payroll tax most employers need to manage.
Employers pay this tax directly it is never deducted from employee paychecks.
New Hampshire assigns experience-based rates based on each employer's ratio of unemployment benefits charged to their account versus the wages they've paid. New Hampshire also has the ability to adjust rates quarterly rather than only once a year, so employers should watch for updated notices throughout the year rather than assuming a single annual rate applies for all four quarters.
Key Facts
- Paid entirely by employers
- Calculated on the first $14,000 of each employee's wages per year
- New employers generally pay a flat 2.7% rate (lower introductory rates may apply to certain household employers)
- Experienced employers are rated based on claims history, with published ranges varying somewhat by source commonly cited as roughly 0.1% to 7.0% or higher so employers should confirm their specific assigned rate directly through NHES rather than relying on a generic published range
- New Hampshire can adjust rates quarterly, so it's worth watching for updated rate notices rather than assuming a single rate for the full year
- Must be reported to NHES every quarter, even if no wages were paid
New Hampshire Has No State Income Tax
Unlike most states, New Hampshire employers do not withhold any state income tax from employee wages. Historically, New Hampshire taxed interest and dividend income (though not wages) through a separate Interest and Dividends Tax, but that tax was fully phased out effective January 1, 2025. As of 2025, there is no state-level income tax of any kind in New Hampshire on wages, interest, dividends, or any other form of individual income.
This means employers:
- Do not need a state withholding account
- Do not need a state withholding certificate equivalent to a W-4
- Do not file any state income tax withholding returns
Employers should still confirm current requirements directly with New Hampshire Employment Security, since payroll rules can change even in a state with this level of simplicity.
Which Payroll Taxes Are Paid by Employers vs Employees?
| Tax | Employer Pays | Employee Pays |
|---|---|---|
| Unemployment Insurance (UI) | YES | NO |
New Hampshire keeps this about as simple as it gets: employers fund UI entirely out of pocket, and there's no income tax withholding of any kind for employees to contend with.

New Hampshire's 2026 UI wage base is $14,000. Published experienced-employer rate ranges vary somewhat between sources; employers should confirm their specific assigned rate directly through their NHES employer account rather than relying on a generic published range.
Instead of memorizing a specific rate, employers should focus on checking their current NHES rate notice, watching for any mid-year rate adjustments, and filing returns on time.
Understanding Taxable Wages
New Hampshire UI tax applies to taxable wages up to the annual wage base of $14,000. Taxable wages generally include:
- Hourly wages
- Salaries

| April – June | July 31 |
| July – September | October 31 |
