New Hampshire Payroll: Employer Tax and Software Guide

New Hampshire is the easiest state in the country to run payroll in, right up until someone crosses a border. There is no state income tax on wages, no state withholding form, no local wage tax, no state disability contribution, and no mandatory paid leave deduction. A ten-person company in Nashua files one state payroll return a quarter, and that return goes to a single agency.

The catch is that simple is not the same as free of obligation. The state taxes compensation through a business tax rather than a payroll deduction, wages are due weekly by default with anything slower than biweekly requiring written permission from the labor commissioner, a discharged employee has to be paid in full inside 72 hours, and the unemployment rate is adjusted quarterly rather than annually. Then there is geography. Massachusetts sits ten minutes from most of the southern tier, and one hire on the other side of that line imports an entire withholding and paid leave regime the New Hampshire employer has never had to think about.

This guide covers what New Hampshire requires from employers as of August 2026, the obligations that unemployment registration does not cover, and how 10 payroll providers price the work at 10, 25, and 50 employees.

What New Hampshire requires from employers

Three obligations sit on top of federal payroll, and only one of them is a payroll filing. That is the shortest list of any state in New England, and it is the reason employers relocate here.

No state income tax withholding, and what that does not remove

New Hampshire does not tax wages, salaries, tips, or any other earned income, and no city or county levies a local income tax. There is no state equivalent of the W-4, no state withholding tables, no deposit schedule, and no annual reconciliation return. The state also stopped taxing investment income: the Interest and Dividends Tax was repealed for tax periods beginning on or after January 1, 2025, which retired the last piece of personal income taxation in the state.

None of that touches the federal side. Federal income tax withholding still runs off the employee Form W-4, Social Security and Medicare still come out of every check, the employer still matches FICA, and FUTA still applies. Roughly speaking, the state removes one line from the paystub and one set of returns from the calendar. It does not shorten the payroll run itself.

Unemployment insurance contributions

Unemployment insurance is the one genuine state payroll tax here, and it is employer funded with nothing deducted from employee pay. According to New Hampshire Employment Security, every new employer starts at a rate of 2.7 percent applied to the first $14,000 of annual wages per employee, minus whatever fund balance reduction is in place for that quarter.

The $14,000 taxable wage base is among the lowest in the country, and it changes the shape of the cost. A 25-person New Hampshire employer with an average salary of $70,000 pays contributions on $350,000 of taxable wages, not on $1.75 million, and every employee stops accruing unemployment tax within the first quarter of the year. At the 2.7 percent new employer rate less the 1.00 percent reduction currently in place, that is a net 1.7 percent on $350,000, or about $5,950 for the whole company for the year.

After the first year the flat new employer rate is replaced by an experience rating that reflects both payment history and how much in benefits the state paid to former employees. Rates come from three published schedules.

The quarterly adjustment is the part outsiders miss. Under RSA 282-A:82 the state trust fund has to hold at least $350 million throughout the preceding calendar quarter before the 1.00 percent reduction applies to positive rated employers. New Hampshire Employment Security has published that 1.00 percent reduction in every quarter since the second quarter of 2023, with no emergency power surcharge across that run and a matching 0.5 percent inverse rate surcharge on the negative schedules under RSA 282-A:82-a. The figure is posted one quarter at a time on the tax rate chart, so read the current quarter rather than assuming last year carried over. To claim the reduction an employer has to be in balance by April 30 of the merit rate year, with all quarterly reports and payments submitted by that date.

One more mechanic worth knowing: the net rate is not all unemployment. New Hampshire Employment Security allocates part of it to an administrative contribution, so a net rate of 1.7 percent is reported as 0.4 percent administrative contribution and 1.3 percent unemployment insurance. The employer pays the same total either way, but the split shows up on the quarterly report and confuses people reconciling against a general ledger.

Pay frequency and the timing rules

New Hampshire regulates when wages are paid more tightly than most states. RSA 275:43 requires every employer to pay all wages due within 8 days after the end of the work week on a weekly schedule, or within 15 days after the end of the work week on a biweekly schedule, on regular paydays designated in advance and at no cost to the employee. The New Hampshire Department of Labor enforces this subdivision, takes the petitions for any other schedule, and publishes the state minimum wage as the federal rate of $7.25 per hour, in force since August 21, 2011 under RSA 279:21.

Anything less frequent than biweekly requires written permission from the labor commissioner, granted on petition showing good and sufficient reason, and it can never be less frequent than once each calendar month. That includes semi-monthly, which most payroll platforms present as an ordinary dropdown option alongside weekly and biweekly. A New Hampshire employer who picks semi-monthly during setup without filing for permission is out of compliance from the first run, and the department can also require weekly payment temporarily where an employer has deficiencies to fix.

Registration, new hire reporting, and workers compensation

Registration is a single account with New Hampshire Employment Security, which opens the unemployment insurance record and the quarterly tax and wage report obligation. Because there is no wage withholding, there is no second account to open with the Department of Revenue Administration. New hires, rehires, and independent contractors under a contract for labor or services exceeding $2,500 are reported to the state new hire program within 20 days.

Workers compensation coverage is required under RSA 281-A:5 from the first employee, full time or part time, with no headcount exemption and no exception for family members or nonprofits. At 15 or more employees, RSA 281-A:64 adds a written safety program filed with the commissioner and reviewed at least every two years, plus a joint loss management committee with equal employer and employee representation. Missing either can draw an administrative penalty of up to $250 a day.

The local layer that state registration does not cover

New Hampshire has no municipal payroll tax, no local income tax, and no city minimum wage, so the local layer here is not municipal at all. It is three things that unemployment registration does not touch: the labor department relationship, the voluntary paid leave plan, and the state line.

The labor department obligations that no payroll system files

RSA 275:49 requires every employer to notify employees at the time of hiring of the rate of pay and the day and place of payment, to notify them of changes before those changes take effect, and to make employment practices and policies on vacation pay, sick leave, and other fringe benefits available in writing or by posted notice. Employers must furnish a statement of deductions for every pay period in which deductions are made, and keep wage and hour records for three years.

None of that is a filing, which is exactly why it gets skipped. There is no return that bounces and no notice that arrives. It surfaces during a wage claim, when the employer is asked to produce a written pay rate notification from the date of hire and a signed authorization for every voluntary deduction, and cannot.

The counterintuitive line is the second one. An employee who gives proper notice triggers the faster 72 hour deadline, while an employee who walks out triggers the slower next-payday standard. Employers who remember the rule as a discharge rule get the notice case wrong, and it is the case where the departing employee is most likely to be paying attention.

Paid family leave is a purchase, not a payroll tax

New Hampshire has no statewide paid sick leave mandate and no mandatory paid family leave contribution. What exists is the Granite State Paid Family Leave Plan, a voluntary state-sponsored program funded by insurance premiums rather than a payroll tax. An employer that buys the six-week group plan through the state program can claim a credit against the business enterprise tax equal to 50 percent of the premium it pays each year.

For payroll purposes the important part is what is absent. There is no state fund to remit into, no mandatory employee deduction to configure, no wage cap to track, and no annual rate reset. Where an employer does elect coverage and shares the premium with employees, that share becomes a voluntary deduction and needs the written authorization RSA 275:48 requires.

The border is the real complexity

Southern New Hampshire is commuter territory, and the state line is where the simple payroll ends. A New Hampshire employer with one employee working in Massachusetts registers for Massachusetts withholding, collects that state's withholding certificate, files on that state's deposit schedule, and enters the Massachusetts Paid Family and Medical Leave system, which does carry a contribution. Push a little further south and Rhode Island adds a temporary disability contribution that has no New Hampshire counterpart at all.

The practical version: compare what a Massachusetts payroll requires against the single New Hampshire quarterly return, and the same gap appears against Connecticut and Rhode Island for anyone hiring further down the corridor. New Hampshire employers do not build multi-state muscle at home, so they buy it in software or they learn it the hard way.

10 payroll providers for New Hampshire employers compared

Every provider below files the New Hampshire quarterly tax and wage report. Because there is no state withholding, no local tax, and no paid leave contribution to differentiate on, the meaningful differences here are multi-state pricing, whether the platform respects the weekly or biweekly pay timing rule, and how quickly it picks up a quarterly rate change.

OnPay

One plan at $49 per month plus $6 per employee, with every feature included and no tiers to climb. Tax filing covers all 50 states with no multi-state surcharge, and year-end W-2 and 1099 filing sits in the base price rather than being billed separately. For a New Hampshire employer, that flat multi-state structure is the whole argument: the day a Massachusetts hire lands, the bill does not move.

Gusto

The most common first payroll purchase for US small businesses. Tax filing is automatic, the interface is pleasant, and pricing is published. Simple runs $49 per month plus $6 per employee following a base increase in March 2026.

The catch for New Hampshire employers is sharper than it is elsewhere. Simple covers single-state payroll only, and a New Hampshire company is unusually likely to hire across a line: a hire in Massachusetts, Maine, or Vermont moves you to Plus at $80 plus $12 per employee. Model the Plus number from day one rather than the Simple number.

Patriot Software

The cheapest legitimate full-service payroll available. Full Service is $37 per month plus $5 per employee and includes federal, state, and local tax filing plus new hire reporting. Basic is $17 plus $4 if you file taxes yourself, which in New Hampshire is a genuinely small job: one quarterly report to one agency and no monthly deposits to the state at all.

That makes New Hampshire one of the few states where the do-it-yourself tier is a defensible choice rather than a trap. Additional state filings cost $12 per month each, which is the number that decides it for anyone with a border hire in view.

Square Payroll

Square is $35 per month plus $6 per employee with multi-state filing included at no extra charge, and it is the natural fit for the hospitality and retail businesses that make up a large share of New Hampshire employment. Tip handling, hourly scheduling, and point-of-sale integration are native rather than bolted on, which matters in a state where tipped employees earn a base rate set at 45 percent of the applicable minimum wage.

SurePayroll

Owned by Paychex and aimed at very small employers and household employers. Full Service is $29 per month plus $7 per employee, with a flat $9.99 monthly multi-state fee regardless of how many states are involved. For a New Hampshire business with a couple of people over the Massachusetts line, that flat structure beats per-state pricing quickly.

QuickBooks Workforce Payroll

Formerly QuickBooks Payroll, now renamed. Core is $50 per month plus $6.50 per employee. The reason to pick it has always been the same: if your books already live in QuickBooks Online, payroll entries reach the general ledger without an export step, which also makes the annual business enterprise tax return easier to assemble because compensation is already categorized. Per-employee pricing rose across all tiers on July 1, 2026.

ADP RUN

ADP processes payroll for roughly one in six American workers and has the deepest tax compliance engine in the category. For a New Hampshire employer the practical argument is entirely about the border: registering in Massachusetts, entering that state's paid leave system, and keeping three New England withholding regimes current is the work ADP is actually built for.

The cost is opacity. ADP does not publish RUN pricing; third-party estimates put Essential near $79 per month plus $4 per employee, but every quote is individual. Contracts typically run a year with automatic renewal and a 30 to 60 day cancellation window.

Paychex Flex

Paychex competes with ADP on the same terms, a service relationship rather than a software subscription, but publishes an entry rate: Essentials is $39 per month plus $5 per employee. That makes it one of the few options where a named support contact and a published price coexist. Higher tiers are quoted individually, and quarterly administrative charges appear regularly in customer reports.

Paylocity

Paylocity sits between small-business payroll and full HCM, aimed at companies that have outgrown basic payroll but do not want enterprise complexity. It maintains detailed per-state tax resources, and leave accrual tracking is native, which matters in New Hampshire precisely because the state mandates nothing: every accrual rule is your own policy and has to be enforced by the system rather than by statute. Pricing is quote-based and implementation is a project.

Rippling

Rippling sells a unified employee record where payroll, HR, and IT provisioning share one data model. The core platform is $35 per month plus $8 per employee, with payroll as a separate module. Real-world all-in costs land between $25 and $45 per employee per month once you assemble a working configuration.

The New Hampshire argument is address resolution. When an employee moves from Nashua to Lowell, the HR record change propagates into tax resolution automatically instead of waiting for someone to notice that a new state registration is now overdue.

What each provider actually costs a New Hampshire employer

The table below models published rates at three headcounts, plus what happens when a second state enters the picture. That last column deserves more weight in New Hampshire than almost anywhere else, because the in-state work is light enough that it barely separates the field.

Patriot stays cheapest at every headcount, and at 50 employees it costs less than several competitors do at 25. Paychex Flex Essentials sits within a few dollars of it, which is unusual for a service-model provider. But the second-state column reorders things immediately: Gusto Simple is competitive until one Massachusetts hire forces the Plus tier, at which point a 25-person payroll goes from $199 to $380 per month, while OnPay and Square do not move at all.

Software price is also not the whole New Hampshire number, though it is closer to it here than in most states. A 25-person employer with a $1.75 million payroll owes roughly $9,600 a year in business enterprise tax at 0.55 percent, assuming the enterprise value tax base is essentially compensation, plus about $5,950 in unemployment contributions on $350,000 of taxable wages at a net 1.7 percent. Those are statutory costs no provider changes, but they belong in the budget alongside the subscription.

Choosing a payroll provider for New Hampshire

Four questions separate providers that will work here from providers that will quietly create a problem. None of them is about state withholding, because there is none.

One item sits outside the payroll engine entirely. Every New Hampshire new hire needs a federal I-9 and W-4, a written notification of the pay rate and the day and place of payment under RSA 275:49, a direct deposit authorization, a written authorization for any voluntary deduction, and a new hire report inside 20 days. None of it is a state tax form, and all of it is a document you have to be able to produce later.

Before you choose

FirstHR does not process payroll, file payroll taxes, move money, or administer benefits. Every provider above does something we do not, and if running payroll is the problem in front of you, one of them is the answer.

What we handle is the layer that feeds payroll: onboarding workflows, e-signatures on I-9s and offer letters, employee records, and HR document management for small US teams at a flat $98 to $198 per month. New Hampshire is a state where an unusual share of the compliance surface is documentary rather than fiscal.

There is no withholding return to get wrong, but there is a written pay rate notification at hire, a signed authorization behind every voluntary deduction, a posted policy on vacation and sick pay, three years of wage and hour records, and a 20-day new hire report. If the recurring problem is that none of those can be produced on request, that is a document collection failure rather than a payroll processing failure, and it is the kind of gap we built for.

Frequently Asked Questions

Does New Hampshire have a state income tax on wages?

No. There is no tax on wages, salaries, or tips, no state withholding form, and no local income tax anywhere in the state. The Interest and Dividends Tax was repealed for tax periods beginning on or after January 1, 2025, ending personal income taxation entirely. Federal withholding, FICA, and FUTA still apply unchanged.

What is the New Hampshire unemployment tax rate and wage base?

New employers pay 2.7 percent on the first $14,000 of annual wages per employee, minus the fund balance reduction in effect that quarter. After the first year, experienced rates come from the three schedules in RSA 282-A:87: Schedule I tops out at 2.6 percent for positive rated employers and falls to the 0.1 percent statutory minimum, Schedule II runs 2.8 to 6.5 percent, and Schedule III runs 3.3 to 7.0 percent.

What is the New Hampshire fund balance reduction?

A quarterly reduction applied to positive rated employers when the state trust fund holds at least $350 million throughout the preceding quarter under RSA 282-A:82. It has been published at 1.00 percent in every quarter since the second quarter of 2023, with a matching 0.5 percent inverse rate surcharge on the negative schedules under RSA 282-A:82-a. Read the current quarter off the tax rate chart rather than assuming last year carried over.

What is the New Hampshire minimum wage?

The federal rate, currently $7.25 per hour. RSA 279:21 sets the state floor at whatever the federal minimum wage law provides, as amended, so there is no separate state figure, no indexation, and no scheduled increase. The state minimum moves automatically whenever Congress raises the federal rate.

What is the tipped minimum wage in New Hampshire?

Tipped employees of a restaurant, hotel, motel, inn, cabin, or ballroom who regularly receive more than $30 a month in tips get a base rate of not less than 45 percent of the applicable minimum wage, roughly $3.26 against the federal floor. Where wages plus tips fall short of the full minimum, the employer pays the difference.

How often do New Hampshire employers have to pay employees?

Weekly, with wages due within 8 days after the end of the work week, or biweekly within 15 days. Anything less frequent, including semi-monthly, requires written permission from the labor commissioner under RSA 275:43 and can never be less often than monthly. Paydays must be designated in advance.

When is a final paycheck due in New Hampshire?

Within 72 hours when the employer discharges the employee, and also within 72 hours when the employee quits after giving at least one pay period of notice. A quit without notice, or a layoff, moves the deadline to the next regular payday. Accrued vacation, sick, holiday, and severance pay count as wages where policy provides them.

Does the New Hampshire Business Enterprise Tax apply to payroll?

Yes, indirectly. The tax is assessed at 0.55 percent on the enterprise value tax base, defined as compensation paid or accrued plus interest paid or accrued plus dividends paid, for taxable periods ending on or after December 31, 2022. A return is required once gross receipts or the enterprise value tax base exceed $298,000, and that threshold is adjusted biennially.

Do New Hampshire employers withhold anything from wages for the state?

Nothing at all. There is no state income tax, no disability contribution, no paid leave deduction, and no local wage tax. Unemployment contributions are employer-funded and never deducted from pay. The only lawful deductions are federal items, court-ordered withholding, and the categories RSA 275:48 permits with specific written authorization from the employee.

How do I register a business for New Hampshire payroll taxes?

One account with New Hampshire Employment Security opens the unemployment record and the quarterly tax and wage report. There is no second withholding account to open because there is no wage tax. New hires and reportable contractors go to the state new hire program within 20 days, and workers compensation is required from the first employee.

Does New Hampshire require paid sick leave or paid family leave?

No. There is no statewide paid sick leave mandate and no mandatory paid family leave contribution. The Granite State Paid Family Leave Plan is voluntary and premium-funded rather than tax-funded, and an employer that buys the six-week group plan through the state program can claim a credit against the business enterprise tax equal to 50 percent of the premium it pays each year.

What happens when a New Hampshire employer hires someone in Massachusetts?

The employer registers for Massachusetts withholding, collects that state's withholding certificate, files on its deposit schedule, and enters the Massachusetts paid family and medical leave system, which carries a contribution. Maine and Vermont bring their own withholding regimes and indexed minimum wages. This is why multi-state pricing decides provider choice here.

What are the New Hampshire workers compensation and safety requirements?

Coverage is required under RSA 281-A:5 from the first employee, full or part time, with no exemption for family members or nonprofits. At 15 or more employees, RSA 281-A:64 adds a written safety program filed with the commissioner and updated at least every two years, plus a joint loss management committee, with penalties up to $250 a day for noncompliance.

How much does payroll software cost for a New Hampshire small business?

At 10 employees, published July 2026 rates run roughly $87 for Patriot Full Service, $89 for Paychex Flex Essentials, $95 for Square, $99 for SurePayroll, $109 for OnPay or Gusto Simple, and $115 for QuickBooks Core. At 50 employees the same plans land between $287 and $379, and the multi-state fee is what actually separates them.
