New Hampshire operates under a distinctive tax framework that sets it apart from nearly every other state—no general sales tax and no personal income tax on wages. Instead, the state relies on the Business Profits Tax (BPT) and Business Enterprise Tax (BET) to generate revenue from business activities.
Unlike the transaction-based economic nexus thresholds that dominate compliance discussions in sales tax states, New Hampshire's nexus rules center on business income and enterprise value.
New Hampshire does not impose a general statewide sales tax, making it one of only five U.S. states without this tax structure. This unique position eliminates the need for businesses to understand economic nexus thresholds, physical presence requirements, or sales tax collection obligations within New Hampshire itself.
Since New Hampshire lacks a sales tax, there are no economic nexus rules requiring remote sellers to register and collect tax based on sales volume or transaction counts. Businesses selling into New Hampshire, regardless of sales amounts, face no sales tax collection obligations to the state.
Traditional physical presence nexus triggers, such as maintaining offices, warehouses, inventory, or employees for sales tax purposes, don't create sales tax obligations in New Hampshire because there's no sales tax to collect. However, physical presence can still trigger other tax obligations, like business profits tax or employment taxes.
New Hampshire doesn't impose traditional corporate or individual income taxes but instead levies the Business Profits Tax and Business Enterprise Tax on qualifying business activities within the state.
The Business Profits Tax applies at a 7.5% rate to corporations, partnerships, and proprietorships with gross business income exceeding $103,000 from New Hampshire activities. Nexus is established through physical or economic presence sufficient to meet constitutional due process standards, including maintaining property, employees, or regular business activities in the state.
Out-of-state businesses must apportion their net income based on New Hampshire activities using factors like sales, property, and payroll.
The Business Enterprise Tax levies a 0.55% rate on the enterprise value tax base (salaries, interest, dividends, and compensation) for businesses exceeding either $298,000 in gross receipts or $298,000 in enterprise value tax base annually. This tax applies regardless of BPT obligations and requires separate registration and filing.
Annual returns for the New Hampshire Business Profits Tax and Business Enterprise Tax must be filed on NH-specific BPT and BET forms, typically due by April 15 for calendar-year taxpayers.
Employment tax nexus in New Hampshire is triggered immediately upon hiring any employee who performs work within the state, regardless of business revenue or other activity levels.
Any employee working from a New Hampshire location, whether full-time, part-time, seasonal, or remote workers establishes employment tax nexus. This includes temporary assignments and employees spending limited time in the state for business purposes. The key factor is where work is physically performed, not where the employee is officially based.
Remote workers hired to work from their New Hampshire homes create the same nexus obligations as employees working in traditional New Hampshire offices, requiring immediate registration and ongoing compliance with state employment tax requirements.
Employment nexus requires registration for unemployment insurance taxes through the New Hampshire Department of Employment Security. All employers with qualifying employees working in New Hampshire must register and pay unemployment insurance taxes, with additional requirements for workers' compensation coverage and new-hire reporting within seven days of employment.
Unlike other states, New Hampshire doesn't require income tax withholding on regular wages since there's no personal income tax on employment income, though a limited 5% tax applies to interest and dividends received by individuals.
New Hampshire's unique tax structure creates specific considerations for digital businesses and remote work arrangements that differ significantly from traditional sales tax nexus concerns.
Digital products and SaaS offerings sold by New Hampshire businesses don't create in-state sales tax obligations since no sales tax exists. However, these businesses must monitor economic nexus thresholds in destination states where their digital products may be subject to sales tax.
New York, Massachusetts, and other states like Delaware tax certain digital products and services, requiring New Hampshire businesses to register and collect tax when crossing those states' economic thresholds.
Reaching business tax or employment nexus in New Hampshire may also result in the need for foreign registration with the Secretary of State. While New Hampshire focuses on tax obligations rather than traditional "doing business" thresholds, substantial business activity that triggers BPT or BET obligations often indicates the level of activity that requires foreign entity registration.
Once nexus thresholds are crossed, New Hampshire requires prompt registration and ongoing compliance with specific filing and payment obligations that differ from traditional sales tax compliance.
Business tax registration occurs through the New Hampshire Department of Revenue Administration using Form DP-1, required before conducting taxable business activities or with the first return filing after thresholds are exceeded.
Employment tax registration must occur before paying the first New Hampshire employee, with unemployment insurance registration through the Department of Employment Security.
New Hampshire requires multi-state businesses to maintain detailed apportionment factor calculations for tax purposes, including records related to New Hampshire-source business income, and, where relevant, property and payroll information used in apportionment calculations.
