Selling a business in Maine.
Masswell advises Maine owners on confidential sales of trades, manufacturing, distribution and professional services businesses — including a new 2026 income surcharge that can affect sale proceeds.
- Tax on the gain
- Taxed as ordinary income (top rate 7.15%), plus a new 2% surcharge on income over $1M ($1.5M joint) from 2026.
- Before closing
- Buyers must withhold for the seller’s unpaid taxes or become jointly liable; a tax clearance letter is the usual fix.
- Trade licenses
- Electrical, plumbing and fuel licenses are individual; permits must be pulled by licensed masters.
- Non-competes
- Employee non-competes are restricted by statute; sale-of-business covenants fall under common law.
What buyers see in Maine.
Maine is the most oil-dependent state in the region — about 49% of homes heated with fuel oil in 2020 — and it has led the country in heat pump adoption, reaching 100,000 installations in 2023, two years ahead of goal, and setting a target of 175,000 more. That makes heating, fuel and HVAC businesses especially active.
The population reached a record 1.41 million in 2025, with all growth coming from people moving in.
Industries we advise in Maine:
How a sale is taxed in Maine
- Capital gains are taxed as ordinary income, with brackets of 5.8%, 6.75% and 7.15%.
- L.D. 2212, signed April 9, 2026 and retroactive to January 1, 2026, adds a 2% surcharge on income over $1 million (single) or $1.5 million (joint). A large 2026 sale gain is likely to be affected — confirm with your CPA.
- Corporate income tax runs from 3.5% to 8.93%, relevant to asset sales inside C corporations.
Tax clearance and successor liability
- Maine Revenue Services advises that a buyer of a business, or of its stock-in-trade in bulk, is required to withhold the seller’s unpaid taxes from the price — otherwise the buyer is jointly and severally liable for them, with interest and penalties.
- The usual solution is for the seller to obtain a tax clearance letter from the MRS Compliance Division before closing.
- Sales tax registration certificates are not transferable; the buyer registers separately.
When a trades business changes hands
- Electrical: Maine licenses electrical companies that employ licensees, and permit applications must be submitted by a licensed master or limited electrician.
- Plumbing is licensed through the Plumbers’ Examining Board; oil, solid fuel, propane and natural gas work is licensed through the Maine Fuel Board — both on an individual basis.
- Because licenses follow people, buyers focus on whether licensed masters and technicians will stay after the sale.
Seller non-competes in Maine
Maine restricts employee non-competes by statute — they are banned for workers earning at or below 400% of the federal poverty level. The statute doesn’t address covenants given by an owner selling a business, which are judged under common-law reasonableness.

Selling a business in Maine: FAQ
Does Maine’s new surcharge apply to the sale of my business?
Likely, if your 2026 income exceeds $1 million (single) or $1.5 million (joint). The 2% surcharge was enacted in April 2026, retroactive to January 1. Talk to your CPA about timing and structure before you close.
Do I need a tax clearance to sell a business in Maine?
Buyers will usually require one. Maine makes a buyer jointly liable for the seller’s unpaid taxes unless enough of the price is withheld, so sellers typically obtain a tax clearance letter from Maine Revenue Services.
How do licenses transfer when I sell a Maine trades business?
Licenses belong to individuals, not the company. Buyers will want licensed masters and technicians to stay on, and someone licensed to pull permits after closing.
What is my Maine business worth?
Most owner-led businesses we see are valued at roughly 3x–4x EBITDA below $1 million of EBITDA, 4x–7x between $1 million and $5 million, and 6x–9x above $5 million. Try our business value estimator for a quick range.
Do buyers want heating and HVAC businesses in Maine?
Yes. Maine’s heavy reliance on fuel oil and its rapid heat pump adoption create steady service, replacement and conversion work that buyers value — especially businesses with recurring service agreements.
