Quick answer

Does New Hampshire really have no income tax — and what do businesses pay instead?

As of January 1, 2025, New Hampshire has no personal income tax of any kind— the old Interest & Dividends tax was fully repealed — and no sales tax. But businesses still owe two taxes: the Business Profits Tax (BPT) at 7.5% on taxable profits, and the unusual Business Enterprise Tax (BET) at 0.55%on your enterprise base (compensation plus interest and dividends paid) — which can bite even when profits are thin. Because there's no owner-level income tax, there's no PTET to elect; planning here is federal-first, plus managing the BPT/BET and Massachusetts-border nexus.

How We Help

Real Scenarios. Real Outcomes.

These are the situations we see most often with New Hampshire businesses — and what changes when the financial foundation is built right.

01Entry Scenario

When the Bank Says No — And the Books Are Why

What This Unlocks

Clean financials unlock things that messy books never can: a readable P&L that shows true profitability, a balance sheet that supports a credit application, and a business that looks like what it actually is. The work is the same. The financial picture is completely different.

$45K
line of credit, approved
Landscaping / Trades
Portsmouth / Seacoast
Here is a situation we see regularly with small contractors along the Seacoast and in the Manchester corridor. A landscaping company at $220K in revenue — profitable, busy, and growing. The owner has been in business for three years. He needs a $45K line of credit to cover equipment and payroll through the winter. The bank says no.

The Problem

The reason is not the business. The business is doing fine. The reason is the books. Personal and business expenses are mixed. The P&L shows uneven revenue because some deposits were coded as owner contributions and some were not. There is no clear picture of what the business actually earns. From a lender's perspective, it looks like a hobby, not a company.

02Bookkeeping Review

The Books Looked Fine. They Weren't.

What This Unlocks

A cheaper bookkeeper records what happens. A good one understands what it means — and knows the difference between a capital contribution and revenue, between an asset purchase and an expense. That distinction alone is often worth more than several years of bookkeeping fees.

potential tax overpayment avoided
Small Business
Manchester / Nashua
We regularly see this: a business has been with a cheaper bookkeeping service for years. On the surface the books look okay — revenue is recorded, expenses are categorized, reports arrive on time. The owner has no reason to think anything is wrong.

The Problem

Review the books in detail, though, and two problems show up again and again. First, owner capital contributions get coded as revenue — inflating taxable income and making the owner pay federal income tax on money that was already their own. Second, major equipment purchases get coded as owner contributions rather than fixed assets, so there's no depreciation schedule, no Section 179 deduction, and thousands of dollars in legitimate write-offs that never happen. An owner in this spot can end up preparing to write a check to the IRS for taxes they don't actually owe. They don't have to.

03Growth Path

From $350K to $1.8M — Without the Owner Doing Everything

What This Unlocks

What the path to $1.8M looks like when the financial systems keep pace: margin by client and service type, a monthly P&L the owner can actually read, and controller-level oversight that lets him delegate with confidence. By year three, the owner is not managing every ticket — he is managing the business.

IT / Managed Services
Nashua / Manchester
Here is what an IT managed services company in the Nashua corridor often looks like at $350K in revenue. The owner is handling every client relationship, every service call, and every invoice. The business is profitable — but only because he is working 55-hour weeks. He cannot take time off. He does not know which clients are actually profitable.

The Problem

The financial system at $350K is usually the same one that worked at $100K: a bank account, a credit card, and a bookkeeper who reconciles once a month. That system does not tell you your margin by client or service type. It does not tell you that your managed services contracts are running 44% margin while your break-fix work is running 12%. It does not give you the data to hire a service manager and trust him with the numbers.

04Acquisition Readiness

When the Offer Comes, You Have 3 Weeks or 9 Months

What This Unlocks

Businesses that are built with controller-level financial systems from the start are acquisition-ready before the call ever comes. The books are clean. The EBITDA is defensible. The story is clear. That is not luck — it is what good financial infrastructure makes possible.

3 Weeks
vs. 9 months for due diligence
Professional Services / M&A
Manchester / Portsmouth / Concord
New Hampshire's I-93 corridor from Manchester to Portsmouth is seeing real M&A activity in professional services, IT, and specialty trades. PE-backed rollups and strategic buyers are actively looking at businesses in the $1M-$10M revenue range. When the call comes, they move fast.

The Problem

Most small business owners are not ready. Not because the business is not valuable — it is. But because the books were built for tax compliance, not for a buyer's due diligence process. A buyer needs 3 years of clean, auditable financials, an adjusted EBITDA calculation with documented add-backs, and a chart of accounts that makes sense to someone who has never worked in your business. When that is not in place, due diligence that should take 3 weeks takes 9 months — and deals fall apart in the gap.

New Hampshire Tax at a Glance

No Income Tax, No Sales Tax — but Two Business Taxes

As of 2025 New Hampshire has zero income tax of any kind and no sales tax — but businesses still owe the BPT and the unusual BET.

Common Questions

New Hampshire Business Owner FAQs

NH has no income tax. Why do I still have a big state tax bill?

New Hampshire has no tax on wages or salary, but it does have the Business Profits Tax (BPT) at 7.5% on net business income and the Business Enterprise Tax (BET) at 0.5% on enterprise value. For profitable businesses, these add up quickly — and most owners are not planning around them.

I work in Massachusetts but live in New Hampshire. How does that affect my taxes?

This is one of the most common situations we see in southern NH. MA taxes income earned in MA regardless of where you live. If you are a W-2 employee working in MA, your employer withholds MA taxes. If you are a business owner with MA clients, you may have MA nexus. We help you understand the exposure and structure it correctly.

What is the BPT apportionment formula and does it apply to my business?

NH uses a single-sales-factor apportionment formula for the BPT. If you have sales in multiple states, only the NH-sourced portion is subject to BPT. Many NH businesses with out-of-state customers are over-apportioning to NH and overpaying. We review the apportionment calculation as part of our tax planning work.

What does a Controller engagement cost for a NH business?

Controller services typically run $1,500-$4,500/month depending on complexity, transaction volume, and whether you need multi-entity or multi-state work. We scope it after a discovery call.

We are a contractor in the Seacoast area. Do you do job costing?

Yes — job costing for contractors is one of our core services. We set up the chart of accounts, the cost codes, and the reporting so you know your margin on every project before the final invoice goes out.

Who You’re Actually Working With

Two founders who’ve sat on both sides of your financials

You aren’t handed off to a junior bookkeeper. You work directly with the people whose names are on the door — and their backgrounds are exactly the ones a growing business needs in its corner.

Carrie Anderson

Co-Founder · The Lender’s Eye

A former commercial banker and underwriter who personally reviewed 300+ business loans. She knows exactly how a bank reads your financials to decide what you can borrow — because she used to be the one reading them. That’s why our clients’ books come out lender-ready, not just tax-ready.

Jason Anderson

Co-Founder · The Operator’s Eye

A big-firm-trained accountant with a lifelong passion for processes, efficiency, and Six Sigma— made practical, not academic. He builds the job costing, tax strategy, and systems that let a company actually see where its money goes and scale without the wheels coming off.

Both spent years in the oil & gas industry, and both design financial systems from a whole-company view— not just an accounting lens. You get a firm that reads your numbers like a lender and builds systems like an operator.
