1. New Hampshire Has No Sales Tax — Period
Let's get the headline out of the way: New Hampshire has no sales tax. Zero percent. On anything. This applies to all goods and services, including SaaS, software, digital products, physical goods, food, clothing — everything.
There is no state-level sales tax, no local sales tax, no use tax, and no gross receipts tax that functions as a sales tax. New Hampshire is one of only five US states with no general sales tax:
- Alaska — no state sales tax, but local municipalities can impose their own
- Delaware — no sales tax (has a gross receipts tax on businesses instead)
- Montana — no sales tax (some resort areas have a local resort tax)
- New Hampshire — no sales tax of any kind
- Oregon — no sales tax
Among these five, New Hampshire is arguably the "cleanest" no-sales-tax state because, unlike Alaska, there are no local sales taxes either. It's genuinely zero across the board.
2. Implications for SaaS Companies Based in New Hampshire
If your SaaS company is headquartered or incorporated in New Hampshire, the lack of sales tax gives you a clean starting point. But there are several things to understand:
You don't collect NH sales tax (because there is none)
You will never need to register for, collect, or remit sales tax in New Hampshire. There is no sales tax registration, no sales tax return, and no sales tax obligation within the state. This eliminates one layer of compliance for your home state operations.
But you may still owe sales tax in OTHER states
Being based in New Hampshire does not exempt you from collecting sales tax in states where you have nexus. If your SaaS company sells to customers in states that tax SaaS (like Texas, New York, Pennsylvania, or Washington), and you meet those states' economic nexus thresholds, you are required to collect and remit sales tax in those states.
Since the US Supreme Court's South Dakota v. Wayfair decision in 2018, states can require out-of-state sellers to collect sales tax based on economic nexus — typically triggered when you exceed $100,000 in sales or 200 transactions in a state during a year. Being based in a no-sales-tax state does not protect you from these obligations.
NH business taxes you DO need to know about
While New Hampshire has no sales tax and no personal income tax, it does have two business-level taxes that apply to most companies operating in the state:
Business Profits Tax (BPT): 7.5%
The New Hampshire Business Profits Tax is imposed on business organizations (corporations, LLCs, partnerships, sole proprietorships) with gross business income exceeding $92,000. The current rate is 7.5% of taxable business profits (net income). This is essentially New Hampshire's version of a corporate income tax.
The BPT applies to:
- Corporations and LLCs operating in New Hampshire
- Sole proprietorships with NH business income
- Partnerships and S-corporations (passed through to the entity level)
Business Enterprise Tax (BET): 0.5%
The Business Enterprise Tax is an additional tax imposed on the enterprise value tax base, which is essentially the sum of all compensation (wages, salaries, benefits), interest, and dividends paid by the business. The rate is 0.5%. The filing threshold is the same as the BPT ($92,000 in gross business income).
The BET is credited against the BPT, so you're not paying both in full — the BET reduces your BPT liability. But if your BET exceeds your BPT (which can happen for companies with high payrolls relative to profits), you still owe the BET amount.
3. The Interest & Dividends Tax: Repealed
For years, New Hampshire's "no income tax" claim came with an asterisk: the state imposed a 5% tax on interest and dividend income under the Interest & Dividends Tax (I&D Tax). This was a significant consideration for investors, retirees, and anyone with substantial investment income.
The New Hampshire legislature passed a phased repeal of this tax, reducing the rate by 1% per year starting in 2023:
- 2023: 4%
- 2024: 3%
- January 1, 2025: Fully repealed — 0%
As of January 1, 2025, New Hampshire has no tax on interest income, dividend income, or any other form of personal income. Combined with no sales tax, this makes New Hampshire one of only two states (along with Alaska) that have neither a personal income tax nor a state sales tax.
This repeal is particularly significant for SaaS founders and investors who may receive dividend income from their companies or have investment portfolios generating interest and dividend income.
4. Selling TO New Hampshire Customers
If you're a SaaS company based outside New Hampshire and you sell to customers in New Hampshire, the answer is simple: you do not need to collect any sales tax on those sales.
New Hampshire has no sales tax, so there is nothing to collect — regardless of whether you have nexus in the state or not. It doesn't matter if your company is based in Texas, California, or New York. When the customer is in New Hampshire, the sale is not subject to sales tax because New Hampshire does not impose one.
Economic nexus: doesn't apply
The concept of economic nexus is irrelevant in New Hampshire because there is no sales tax for economic nexus to trigger. You can have $10 million in sales to New Hampshire customers and 10,000 transactions — and you still owe zero sales tax on those sales. There is no registration requirement, no filing requirement, and no collection obligation.
Impact on your nexus calculations
When calculating whether you've met economic nexus thresholds in other states, note that each state has its own rules about what counts toward the threshold. Sales to New Hampshire customers do not create sales tax obligations in New Hampshire, but they may count toward your total US sales figure that some states use in their nexus calculations.
5. Comparison with Other No-Sales-Tax States
How does New Hampshire compare to the other four no-sales-tax states for a SaaS business?
| State | Sales Tax | Personal Income Tax | Corporate/Business Tax | Key Consideration |
|---|---|---|---|---|
| New Hampshire | 0% |
0% |
BPT: 7.5%, BET: 0.5% | High property tax (~1.57%) |
| Alaska | 0% state (local possible) |
0% |
Corporate income tax: 2-9.4% | Remote location, high cost of living |
| Delaware | 0% |
2.2-6.6% (graduated) | 8.7% corporate income tax | Has personal income tax |
| Montana | 0% |
4.7% flat rate | 6.75% corporate income tax | Has personal income tax |
| Oregon | 0% |
4.75-9.9% (graduated) | 6.6-7.6% corporate income tax | High personal income tax |
New Hampshire stands out as the only state in this group with no sales tax AND no personal income tax. Alaska also has no personal income tax, but local areas can impose sales taxes. Delaware, Montana, and Oregon all impose personal income taxes, which can be significant.
The trade-off for New Hampshire is property taxes. With no income tax and no sales tax, the state relies heavily on property taxes to fund local services. The average effective property tax rate in New Hampshire is approximately 1.57%, among the highest in the nation. A $400,000 home generates roughly $6,280 in annual property taxes.
