Maine imposes a state estate tax with an exemption of approximately ~$6.80 million per person (indexed for inflation) and a top rate of ~12.00%. Maine’s exemption is among the highest of the estate tax states and has been increasing in recent years as the state indexed it to inflation. While Maine’s estate tax affects a relatively small number of estates, the state’s coastal property values — particularly in vacation-home areas like Bar Harbor, Kennebunkport, and Portland — create meaningful exposure for property owners.

Estimated Tax by Estate Size

Estate ValueEstimated Maine Estate Tax
$6,800,000$0
$7,000,000~$16,000

Maine’s ~8.00% starting rate is moderate, and the top ~12.00% rate is the lowest top rate among states with estate taxes (tied with Connecticut).

Maine’s Indexed Exemption

One of Maine’s most taxpayer-friendly provisions is that the estate tax exemption is indexed for inflation. This distinguishes Maine from many other estate tax states:

StateExemptionIndexed?
Maine~$6.80 millionYes
New York~$6.94 millionYes
Oregon~$1.00 millionNo
Massachusetts~$2.00 millionNo
Minnesota~$3.00 millionNo
Illinois~$4.00 millionNo

Inflation indexing ensures that the exemption maintains its real purchasing power over time, preventing “bracket creep” that gradually subjects more estates to the tax.

Maine Coastal Property Considerations

Maine’s estate tax intersects with the state’s significant real estate wealth along the coast:

AreaTypical Property Values
Portland/South Portland~$500,000 to ~$1,500,000
Kennebunkport~$1,000,000 to ~$5,000,000+
Bar Harbor/Mount Desert Island~$1,000,000 to ~$10,000,000+
Camden/Rockport~$500,000 to ~$3,000,000
York/Ogunquit~$600,000 to ~$2,500,000

Non-residents who own Maine real estate (summer homes, vacation properties) are subject to Maine estate tax on that property, prorated based on the ratio of Maine property to the total estate. This affects many out-of-state families who own coastal vacation homes.

What Is Included in the Maine Taxable Estate

Maine follows the federal gross estate definition:

  • Real property in Maine
  • Financial accounts and investments (for Maine domiciliaries)
  • Retirement accounts (IRAs, 401(k)s)
  • Life insurance proceeds (if the decedent owned the policy)
  • Business interests

Maine allows the unlimited marital deduction and charitable deduction. Assets passing to a surviving U.S. citizen spouse are not subject to Maine estate tax.

Comparison to Other New England States

Maine has the second-highest exemption in New England (after Connecticut) and the lowest top rate (tied with Connecticut). New Hampshire’s complete lack of estate tax makes it the most favorable New England state for wealth transfer.

Tips for Minimizing Maine Estate Tax

  1. Make lifetime gifts. Maine does not impose a state gift tax. Annual exclusion gifts of approximately ~$19,000 per recipient per year reduce the estate without any Maine or federal gift tax.

  2. Use irrevocable trusts. Transferring appreciating assets (particularly coastal real estate) to irrevocable trusts can remove future appreciation from the taxable estate.

  3. Leverage the marital deduction. A credit shelter trust ensures both spouses’ ~$6.80 million exemptions are used, effectively shielding approximately ~$13.60 million for married couples.

  4. Consider a qualified personal residence trust (QPRT). For families whose Maine vacation home represents significant value, a QPRT transfers the property at a discounted value while allowing continued use for a term of years.

  5. Plan for non-resident property ownership. Out-of-state families owning Maine real estate should consider holding property in an LLC, trust, or other structure that may reduce Maine estate tax exposure. Consult a Maine estate planning attorney for the best approach.

  6. Take advantage of the inflation-indexed exemption. As the exemption increases with inflation, some estates that are near the threshold today may naturally fall below it in future years without any active planning.

  • Rates range from ~8.00% to ~12.00%, with the lowest top rate among estate tax states
