Section 125 Plan in New Hampshire: 2026 Employer Guide

• New Hampshire employers recapture $91 to $136 per enrolled employee per month in FICA taxes, based on typical benefit elections between $400 and $600 per month (IRS FICA rate: 7.65% employer-side).
• New Hampshire fully repealed its Interest and Dividends Tax effective January 1, 2025, per the New Hampshire Department of Revenue Administration, making it the only state with no individual income tax and no state sales tax.
• Fidelity Investments employs more than 7,900 workers statewide in New Hampshire, with its Merrimack campus among the largest single-site employers in the state.
• Dartmouth Health is New Hampshire's largest private employer, with more than 13,000 employees, and its Lebanon flagship campus employs more than 8,000 as the state's only academic medical center.
• A New Hampshire employee in the 22% federal bracket electing $480 per month pre-tax takes home roughly $143 more per month after federal income tax and FICA savings combine, with no third state tax layer involved.

Before a BAE Systems electronics technician in Nashua takes home $143 more a month on the same salary, he does one thing: he elects $480 in benefits pre-tax through his employer's Section 125 cafeteria plan. Federal income tax at 22% and FICA at 7.65% come off that $480 before his W-2 is calculated. There is no state income tax line to compute at all. New Hampshire fully repealed its Interest and Dividends Tax on January 1, 2025, so the state now taxes wages, interest, and dividends at exactly zero percent. His employer recaptures $480 x 12 x 7.65% = $441 in FICA savings on him alone, before the first renewal.

How much does a New Hampshire employer actually save on payroll with a §125 plan?

A New Hampshire employer with 70 employees each electing $480 per month in pre-tax benefits saves $30,845 per year in employer FICA taxes alone (70 x $480 x 12 x 7.65%). That calculation uses only the employer's 7.65% FICA share on pre-tax elections. It does not count the federal income tax savings employees receive, and there is no state income tax savings line to add because New Hampshire taxes no wages at the state level. For an employer paying a Benecor admin fee of $35 per enrolled employee per month, the FICA recapture on a $480 election outpaces the fee when monthly elections exceed $458 per employee ($35 divided by 0.0765 = $458), which describes most New Hampshire financial services, defense electronics, and healthcare elections above the individual-only tier. See the full mechanics in Benecor's Section 125 cafeteria plan guide→.

The paycheck comparison below uses a Fidelity Investments client service associate earning $62,000 annual salary with a $460 monthly pre-tax election. Numbers are calculated using the 22% federal bracket and 7.65% FICA on each biweekly paycheck before and after the election, with no state income tax row because New Hampshire has none.

"Our associates always asked why New Hampshire has no state income tax but their health premiums still came out of after-tax pay. The §125 enrollment took less than a week to explain, because there was only one tax rate to walk through instead of three."

How does New Hampshire's lack of an income tax affect a §125 plan?

New Hampshire has no tax on wages, and as of January 1, 2025, it has no tax on interest or dividends either, following the full repeal of the state's Interest and Dividends Tax. That makes New Hampshire one of nine states with no individual income tax, and the only one of those nine that also has no state sales tax, according to the New Hampshire Department of Revenue Administration's public repeal announcement. For a §125 plan, this means the savings model is two layers instead of three or four: federal income tax at each employee's marginal bracket, and FICA at 7.65% employer-side. Most Fidelity Investments, BAE Systems, and Dartmouth Health staff earning between $48,475 and $103,350 in 2026 sit in the 22% federal bracket, so the federal layer remains the larger of the two savings sources on every paycheck.

The Interest and Dividends Tax repeal, explained

New Hampshire's Interest and Dividends Tax was assessed at 5% for tax periods ending before December 31, 2023, reduced to 4% for periods ending on or after December 31, 2023, reduced again to 3% for periods ending on or after December 31, 2024, and then fully repealed effective January 1, 2025, according to the New Hampshire Department of Revenue Administration's 2025-001 Technical Information Release. That repeal removed the state's only remaining tax on personal income, since New Hampshire has never taxed wages directly. For §125 purposes, the repeal is mostly symbolic for W-2 wage earners, since the Interest and Dividends Tax never applied to payroll wages in the first place. It confirms that New Hampshire's tax treatment of a §125 election will not change from a state income tax angle in any future year without new legislation.

No city or county income tax anywhere in New Hampshire

New Hampshire levies no local income tax on wages in any city or county in the state. Manchester, Nashua, Portsmouth, Concord, Lebanon, and every other New Hampshire municipality impose zero local income tax on employee wages. This makes New Hampshire the simplest §125 compliance environment Benecor implements in New England. Employers in Massachusetts must track the 4% surtax on income over $1 million. Employers in New York must resolve New York City wage tax withholding for city residents. In New Hampshire, the savings model is two layers and two layers only: federal income tax and FICA. There is no third or fourth layer to configure, document, or reconcile at year-end, from the BAE Systems facilities in Nashua to the Fidelity Investments campus in Merrimack to Dartmouth Health locations statewide.

FICA recapture: the §125 ROI for every New Hampshire employer

The employer-side FICA calculation is straightforward. An employer with 90 BAE Systems subcontract or supplier employees each electing $480 per month saves 90 x $480 x 12 x 7.65% = $39,672 per year in employer FICA. That employer pays Benecor 90 x $35 x 12 = $37,800 per year in admin fees, for a net FICA recapture after fees of $1,872 per year. This calculation does not include the federal income tax benefit delivered to the 90 employees. Because New Hampshire employees keep 100% of their gross wages free of state income tax to begin with, the combined employee value proposition of a §125 election centers on the federal and FICA savings plus the Benecor benefit stack, described next.

What New Hampshire employees actually get with a §125 plan

Every Benecor Health §125 plan includes a benefit stack of supplemental health services at $0 employee cost. New Hampshire employees enrolled in the plan receive unlimited virtual urgent care, unlimited primary care visits, unlimited mental health counseling, access to more than 800 generic medications, and dental, vision, lab, and prescription discount networks at no additional charge. The market value of these supplemental benefits is roughly $5,630 per enrolled employee per year based on average healthcare utilization. For a Southern New Hampshire University staff member paying $340 per month in pre-tax benefit elections, the combination of monthly tax savings and $5,630 per year in supplemental benefit value represents a material improvement in total compensation without a wage increase.

New Hampshire industries with the highest §125 ROI

New Hampshire's economy is concentrated in defense electronics, financial services, healthcare, higher education, and a dense small business base. Each sector has distinct wage distributions, benefit election patterns, and turnover dynamics that affect §125 plan design. The highest FICA recapture per employer dollar occurs in sectors where average wages exceed $60,000 and elections consistently exceed the $458 monthly breakeven. Financial services, defense electronics, and senior healthcare roles meet this threshold most reliably, while higher education and retail generate high headcount with moderate per-employee FICA recapture but still deliver meaningful federal income tax benefits.

Defense and electronics: BAE Systems

BAE Systems operates defense electronics and microelectronics facilities across four New Hampshire cities, Nashua, Hudson, Manchester, and Merrimack, with a combined workforce of more than 6,500 people, according to the company's own New Hampshire careers reporting. The Nashua sites include the Electronic Systems headquarters and the Richard Reed Microelectronics Center. The workforce spans electrical engineers, systems engineers, electronics technicians, program managers, supply chain staff, and administrative employees. A BAE Systems electronics technician at $68,000 electing $480 per month saves approximately $143 per month, and a systems engineer at $88,000 electing $560 per month saves roughly $167 per month. Manchester-based DEKA Research and Development, the medical device and robotics firm founded by inventor Dean Kamen, adds further engineering employment to the same southern New Hampshire corridor, all fully eligible for §125 under the same two-layer savings model.

Financial services: Fidelity Investments

Fidelity Investments, the mutual fund and financial services giant, employs more than 7,900 workers across New Hampshire, according to New Hampshire Business Review reporting on the company's statewide workforce, with its Merrimack campus ranking among the largest single-site employers in the town. The workforce includes client service associates, fund operations staff, software engineers, compliance analysts, and administrative personnel. A Fidelity client service associate at $62,000 electing $460 per month saves approximately $137 per month in combined federal income tax and FICA, and the employer recaptures $460 x 12 x 7.65% = $422 per year per enrolled worker. Fidelity's scale in Merrimack alone makes it one of the highest-value single-employer §125 opportunities in the state.

Healthcare: Dartmouth Health and Elliot Health System

Dartmouth Health is New Hampshire's largest private employer, with more than 13,000 employees statewide, according to the health system's published facts and figures. Its flagship Dartmouth Hitchcock Medical Center in Lebanon employs more than 8,000 people and is New Hampshire's only academic medical center. Elliot Health System, based in Manchester, operates one of the state's largest hospital networks across more than 30 locations in southern New Hampshire. Nurses, physicians, technicians, and administrative staff at both systems are W-2 employees fully eligible for §125. A Dartmouth Health registered nurse at $78,000 electing $520 per month saves approximately $155 per month in combined taxes, and the employer recaptures $520 x 12 x 7.65% = $477 per year per enrolled nurse.

Higher education: Southern New Hampshire University

Southern New Hampshire University, headquartered across Manchester and Hooksett, is one of the largest employers in the Manchester metro area, combining its physical campus staff with a much larger online-education workforce, according to the university's own staff directory. Academic advisors, admissions counselors, instructional designers, and administrative staff are all W-2 employees fully eligible for §125. A SNHU academic advisor at $46,000 electing $340 per month saves approximately $67 per month in combined taxes, and the employer recaptures $340 x 12 x 7.65% = $312 per year per enrolled worker. Because SNHU's workforce spans a wide range of entry-level and professional roles, its §125 election amounts vary more than at BAE Systems or Fidelity, but the FICA recapture math holds at every wage tier above the $458 monthly breakeven.

Small business: New Hampshire's 145,000-plus small employers

New Hampshire has 145,314 small businesses, representing 99.0% of all New Hampshire businesses and employing 309,420 people, or 50.3% of the state's private workforce, according to the U.S. Small Business Administration Office of Advocacy's 2025 New Hampshire Small Business Profile. Construction, professional and technical services, and retail trade are the three largest small business sectors by establishment count. A 12-person Nashua machine shop or a 20-person Portsmouth architecture firm qualifies for the same §125 plan structure as BAE Systems, with the same $35 PEPM admin fee and the same 7.65% FICA recapture rate on every enrolled employee's election.

Manchester, Nashua, and secondary New Hampshire markets

New Hampshire's employer base is concentrated in three primary geographic zones. The Manchester-Nashua corridor along the Merrimack Valley houses BAE Systems, Southern New Hampshire University, DEKA Research, and Elliot Health System. The Seacoast region around Portsmouth hosts a dense mix of professional services, tourism, and small manufacturing employers. The Upper Valley around Lebanon and Hanover is anchored by Dartmouth Health and Dartmouth College. All New Hampshire markets share the same absence of state and local income tax, so §125 plan documents and payroll configurations are identical statewide.

Manchester and the Merrimack Valley

Manchester is New Hampshire's largest city and the commercial center of the Merrimack Valley, home to Southern New Hampshire University's physical campus, Elliot Health System's flagship hospital, and DEKA Research and Development. Neighboring Nashua hosts BAE Systems' Electronic Systems headquarters and the Richard Reed Microelectronics Center. Neighboring Merrimack is home to Fidelity Investments' major New Hampshire campus. The Manchester-Nashua wage distribution spans healthcare support staff earning $36,000 to $50,000, electronics technicians earning $58,000 to $80,000, and financial services professionals earning $55,000 to $110,000. Elections in the corridor average $400 to $500 per month depending on industry. See how a neighboring state's much higher tax burden changes the math in Benecor's Massachusetts §125 plan guide→.

Portsmouth and the Seacoast

Portsmouth anchors New Hampshire's Seacoast region, a mix of professional services firms, tourism and hospitality employers, and small advanced manufacturing shops along the Piscataqua River. The Seacoast's wage distribution leans toward professional services and hospitality, with average elections around $470 per month. Even a modest Seacoast employer with 25 professional services employees electing $470 per month recaptures 25 x $470 x 12 x 7.65% = $10,787 per year in employer FICA, comfortably clearing the $10,500 annual admin fee for that group size (25 x $35 x 12).

Lebanon, Hanover, and the Upper Valley

The Upper Valley, spanning Lebanon and Hanover along the Connecticut River, is anchored by Dartmouth Health's Dartmouth Hitchcock Medical Center and Dartmouth College. The region's healthcare and higher education wage base skews higher than the state average, with registered nurses, physicians, and academic staff frequently electing $500 to $600 per month. Even at the lower end of that range, a 100-person Upper Valley healthcare employer recaptures 100 x $500 x 12 x 7.65% = $45,900 per year in employer FICA, well above the $42,000 annual admin fee for that group size (100 x $35 x 12).

New Hampshire compliance: plan documents, ERISA, and the ACA

New Hampshire §125 compliance involves three primary requirements: a written plan document and summary plan description meeting IRS and ERISA standards, payroll deduction codes that correctly reduce W-2 Boxes 1, 3, and 5, and underlying benefit products issued by carriers licensed in New Hampshire. New Hampshire itself imposes no state-specific plan document requirements, no separate plan registration with the New Hampshire Department of Revenue Administration, and no annual state-level filing obligations for the §125 plan wrapper. New Hampshire employers subject to ERISA file IRS Form 5500 at the plan level when applicable under standard federal thresholds, without additional New Hampshire state filings.

Why there is no state conformity question in New Hampshire

Most states start their individual income tax calculation from federal adjusted gross income, which is why a §125 election automatically reduces state taxable wages in those states. New Hampshire skips this question entirely because it has no state income tax on wages to calculate in the first place. There is no state adjusted gross income figure, no state withholding table, and no state-level payroll tax form for a New Hampshire employer to reconcile against a §125 election. The only two payroll tax bases a New Hampshire employer needs to track are the federal W-2 wage boxes and FICA, which simplifies both plan administration and the annual compliance report compared to states like Massachusetts, Connecticut, or Maine.

The non-compliant §125 market: New Hampshire employers must verify their plan

A meaningful share of New Hampshire employers operating pre-tax payroll deductions do so without a written plan document, without an adoption agreement, or with plan documents that have not been updated since original enrollment. A §125 plan without a current written plan document fails to meet the requirements of IRS Treas. Reg. §1.125-1(c), which requires the plan to be in writing before any elections take effect. New Hampshire employers operating informal pre-tax deductions expose themselves to IRS reclassification of all pre-tax elections as after-tax compensation, resulting in FICA and federal income tax liability plus penalties for all open tax years. Small manufacturers around Nashua, retail and hospitality employers along the Seacoast, and small healthcare practices statewide are particularly common in the New Hampshire non-compliant market due to long-standing but undocumented pre-tax arrangements. Benecor confirms plan document compliance as part of every New Hampshire implementation.

ACA employer mandate in New Hampshire

New Hampshire employers with 50 or more full-time equivalent employees are subject to the ACA employer mandate under IRS Code §4980H, requiring them to offer minimum essential coverage to full-time employees or face potential excise tax penalties. A §125 cafeteria plan does not substitute for ACA-compliant minimum essential coverage but works in combination with it: employers use the §125 plan to make ACA-compliant premiums pre-tax for employees, reducing both the employer's FICA obligation and the employee's net cost of required coverage. New Hampshire's lack of a state income tax means the employee-side value of a §125 election in New Hampshire comes entirely from federal income tax and FICA savings plus the Benecor benefit stack, without a state tax boost to the total.

Launching a §125 plan in New Hampshire: the 5-week timeline

A New Hampshire §125 plan goes from signed engagement to first pre-tax payroll in five weeks. Week one covers plan design and document drafting, including the adoption agreement, summary plan description, and election change event policy. Week two covers employee enrollment communications tailored to financial services, defense electronics, healthcare, and higher education workforces statewide. Week three covers payroll deduction code setup and test payroll confirmation across all New Hampshire employee locations. Weeks four and five cover final enrollment, payroll go-live, and the first compliance report comparing actual FICA recapture against the signed savings estimate. New Hampshire's absence of state and local income tax means payroll configuration does not require a state withholding table or a city-by-city rate lookup for Manchester, Nashua, Portsmouth, and Lebanon employees, which eliminates the single most common source of implementation delay Benecor sees in other states.
