You've built a business worth $3 million, maybe $5 million. You've heard that New Hampshire has no income tax and no capital gains tax. And you're thinking: what if I move north before I sell?

You're not the first business owner in Greater Boston to have this idea. Selling your business and moving to New Hampshire is one of the most common tax-planning conversations we have at Nova Exit Partners. But here's the problem — Massachusetts knows you're thinking about it too. And the Department of Revenue has tools, rules, and audit triggers designed to capture exit proceeds from owners who relocate without proper planning.

This isn't a reason to abandon the strategy. It's a reason to understand what Massachusetts can still tax — and to plan your exit timeline accordingly.

Massachusetts Residency Rules Are Stickier Than You Think

Massachusetts uses two tests to determine whether you're a tax resident: the domicile test and the statutory residency test. You fail either one, and the Commonwealth taxes your worldwide income — including your business sale proceeds.

The domicile test asks where your permanent home is. If your family still lives in Newton, your kids are enrolled in Needham schools, and your dentist is in Brookline, Massachusetts will argue you never really left. Changing your driver's license and voter registration isn't enough.

The statutory residency test is simpler and more dangerous: if you maintain a "permanent place of abode" in Massachusetts and spend more than 183 days here in a calendar year, you're a statutory resident. Period. That condo you kept in Cambridge "just in case"? It counts.

A business owner we spoke with last year had moved to Portsmouth, New Hampshire, eighteen months before selling his IT services firm. He'd done almost everything right — new address, new bank, new accountant. But he'd kept a small office in Waltham and was driving down three days a week during the transition. Massachusetts audited him and assessed tax on the full gain. The 183-day rule doesn't care about your intentions. It counts days.

What Massachusetts Can Still Tax Even After You Leave

Let's say you do it right. You're fully domiciled in New Hampshire. You've cut the cord. You sell your business nine months later. Are you clear?

Not necessarily. Massachusetts can still tax:

• Income sourced to Massachusetts. If your business operates here — employees in Worcester, clients along Route 128, an office in Quincy — the gain attributable to Massachusetts operations may still be taxable. This is especially relevant for asset sales where goodwill is tied to a Massachusetts location.
• Installment sale payments. If you structure a seller-financed deal and receive payments over several years, Massachusetts will tax the payments attributable to the period when you were still a resident — or to Massachusetts-sourced income regardless of where you live.
• Noncompete income. If part of your purchase agreement includes a noncompete payment and that noncompete is tied to a Massachusetts geography, the state has a colorable argument that income is sourced here.
• S-corp and partnership income. If you own an S-corp or partnership that continues to operate in Massachusetts after the sale (during an earnout period, for example), that pass-through income is Massachusetts-sourced.

The key concept is sourcing. Even non-residents pay Massachusetts tax on income sourced to the state. And when you're selling a business that's operated in Lexington or Natick for twenty years, a significant chunk of that gain may be deemed Massachusetts-sourced regardless of your new zip code.

The Massachusetts Capital Gains Tax Bite Just Got Bigger

Starting in 2023, Massachusetts implemented the "millionaire's tax" — a 4% surtax on income (including capital gains) exceeding $1 million. Combined with the base 5% income tax rate, that's a 9% state tax rate on gains above $1 million.

For a business owner selling a company for $4 million with a low cost basis, that surtax alone could mean an additional $120,000 in state taxes. This is real money — and it's the primary driver behind the surge of interest in relocating to New Hampshire before a sale.

But the surtax also means Massachusetts has even more incentive to audit relocated business owners. The revenue at stake is too large for the DOR to ignore. Expect scrutiny if you move within two years of a significant liquidity event.

How to Plan This Correctly

We're not tax attorneys, and this isn't tax advice. But after helping dozens of Massachusetts business owners plan and execute exits, here's what we've seen work:

• Start early. A 12-to-24-month gap between your move and your sale gives you the strongest position. If you're thinking about selling in 2026, the relocation conversation should be happening now.
• Make it real. Sell the Massachusetts house. Move your doctors, your banking, your social life. Don't keep an apartment in Boston "for convenience."
• Track your days. Obsessively. Use an app. Keep receipts. Massachusetts auditors will reconstruct your calendar from credit card transactions and EZPass records.
• Structure the deal carefully. How you allocate purchase price between goodwill, assets, noncompetes, and consulting agreements directly affects what Massachusetts can claim. This is where your M&A advisor and tax counsel need to work together.
• Get your business exit-ready first. No relocation strategy matters if your business isn't positioned to sell at maximum value. Clean financials, recast earnings, and a compelling growth story drive multiples — not your zip code.

The owners who execute this well typically save hundreds of thousands of dollars. The ones who rush it — or treat it as a paper exercise — often end up paying Massachusetts anyway, plus penalties and interest.
