Maine's Real Estate Transfer Tax in 2026 is $2.20 per $500 of property value (0.44%) on the first $1,000,000, plus an additional $3.80 per $500 on the portion above $1,000,000 (effective November 1, 2025), bringing the over-$1M rate to $6.00 per $500 (1.20%). The tax is split 50/50 between buyer and seller. On a $2M Maine purchase, total tax is $16,400; the buyer pays $8,200. On a $5M purchase, total tax is $52,400; the buyer pays $26,200. Maine has no mansion tax and no Land Bank fee. Even after the November 2025 tier change, Maine remains the lowest-closing-cost coastal luxury market in the Northeast.
The New Maine Transfer Tax Structure (Effective November 1, 2025)
Maine's Real Estate Transfer Tax ("RETT") changed in a meaningful way for the first time in two decades on November 1, 2025. The statute (36 M.R.S. § 4641-A) was amended to introduce a higher rate on the portion of any transfer that exceeds $1,000,000. The change does not affect transfers at or below $1M, which continue to be taxed under the prior rate structure.
| Portion of Sale Price | Rate per $500 | Effective Percentage | Who Pays |
|---|---|---|---|
| First $1,000,000 | $2.20 | 0.44% | 50% buyer / 50% seller |
| Portion above $1,000,000 | $6.00 ($2.20 base + $3.80 additional) | 1.20% | 50% buyer / 50% seller |

What This Actually Costs at Real Maine Coastal Price Points
The two-tier structure means the effective rate on a Maine purchase rises gradually as the price increases above $1M. The total transfer tax is the sum of 0.44% on the first $1M plus 1.20% on everything above. Both buyer and seller split each tier 50/50.
| Sale Price | Total Transfer Tax | Buyer Pays (50%) | Seller Pays (50%) |
|---|---|---|---|
| $500,000 | $2,200 | $1,100 | $1,100 |
| $1,000,000 | $4,400 | $2,200 | $2,200 |
| $1,500,000 | $10,400 | $5,200 | $5,200 |
| $2,000,000 | $16,400 | $8,200 | $8,200 |
| $3,000,000 | $28,400 | $14,200 | $14,200 |
| $5,000,000 | $52,400 | $26,200 | $26,200 |
| $10,000,000 | $112,400 | $56,200 | $56,200 |
| $19,300,000 (top of current Kennebunkport market) | $224,000 | $112,000 | $112,000 |
Calculations based on Maine RETT formula: $2.20 per $500 on first $1M, $6.00 per $500 on portion above $1M, rounded up to nearest $500 increment. Verified against Maine Revenue Services schedule.
The honest read for Maine buyers: The November 2025 transfer tax change is real and it affects every Maine luxury transaction. On a $4M Kennebunkport property, the buyer-side cost is now $20,200, where it would have been approximately $8,800 under the old single-tier rate. That is a meaningful change, particularly for the Maine prestige tier above $2M. It is also still substantially less than the equivalent buyer-side cost in any other Northeast coastal luxury market. The structural advantage versus Massachusetts and New York remains intact, just narrower than it was before November 2025.
Maine vs. Other Northeast Coastal Markets: The Buyer-Side Cost Comparison
The clearest way to see Maine's continued closing-cost advantage is to compare the buyer-side transfer cost across all five Northeast coastal luxury markets at common price points. Maine's number is the lowest at every tier because the cost is shared 50/50, while the New York mansion tax and the Massachusetts Land Bank fee are 100% buyer-paid.
| Purchase Price | Maine (Kennebunkport) | The Hamptons (NY) | Nantucket (MA) | Newport (RI) |
|---|---|---|---|---|
| $1M | $2,200 | $10,000 | $20,000 | ~$0 |
| $2M | $8,200 | $25,000 | $40,000 | ~$0 |
| $3M | $14,200 | $45,000 | $60,000 | ~$0 |
| $5M | $26,200 | $112,500 | $100,000 | ~$0 |
| $10M | $56,200 | $325,000 | $200,000 | ~$0 |
Buyer-side transfer surcharge only. Excludes attorney fees, title insurance, recording fees, and other standard closing costs. Maine figures reflect 50% of total RETT obligation. Newport RI shown as approximately zero because Rhode Island has no mansion tax or Land Bank fee, only nominal deed transfer.
Maine Property Taxes: How Mil Rates Work
Maine property taxes are administered at the municipal level. Each town and city sets its own annual "mil rate," expressed as dollars of tax per $1,000 of assessed value. The mil rate multiplied by the assessed value (not the market value) gives the annual property tax bill. Assessment ratios vary by town, so two properties at the same market value in different Maine towns can have meaningfully different property tax bills based on both the mil rate and the assessment ratio.
| Component | How It Works |
|---|---|
| Assessed value | Municipal assessor's determination of taxable value, often a fraction of market value |
| Certified ratio | The ratio of assessed to market value declared by the town annually |
| Mil rate | Dollars of tax per $1,000 of assessed value, set annually by the town |
| Annual tax | (Assessed value / 1,000) x mil rate |
For coastal luxury buyers, the practical impact is that two seemingly comparable properties in Kennebunkport and Cape Elizabeth can carry different effective tax burdens because the towns set different mil rates and may use different assessment ratios. Always pull the current mil rate from the specific town assessor's office and confirm the assessment ratio before modeling annual carrying costs.
Property Tax in Kennebunkport and Cape Elizabeth
Both Kennebunkport and Cape Elizabeth are coastal towns in southern Maine that have historically maintained competitive mil rates relative to comparable Massachusetts or New York municipalities. For prestige-tier properties in either town, annual property taxes typically run in these ranges as of 2026:
| Property Value Tier | Kennebunkport Annual Tax | Cape Elizabeth Annual Tax |
|---|---|---|
| $2M | $11,000-$16,000 | $13,000-$18,000 |
| $4M | $22,000-$32,000 | $26,000-$36,000 |
| $8M | $44,000-$64,000 | $52,000-$72,000 |
| $15M | $82,000-$120,000 | $98,000-$135,000 |
Estimates based on typical recent mil rates and assessment ratios. Cape Elizabeth's mil rate has historically run slightly higher than Kennebunkport's. Verify current rates with each town assessor before underwriting any property.
Other Closing Costs Maine Buyers Should Model
Beyond the transfer tax, Maine buyers should budget for the standard closing-cost stack. None of these are unusually high for Maine compared to other states, but they add up for any buyer running a tight underwriting model.
- Attorney fees: Maine is an attorney-state for closings. Budget $1,500 to $4,000 depending on transaction complexity and attorney market rate. Coastal luxury transactions typically run at the upper end.
- Title insurance: Lender's policy is typically required for financed purchases. Owner's policy is optional but recommended for any luxury purchase. Premium scales with purchase price; budget $3,000 to $8,000+ on a $3M to $5M purchase.
- Recording fees: County registry of deeds recording fee, typically under $100 per document.
- Survey: Optional but commonly requested for coastal properties with potential boundary or shoreline access questions. $1,500 to $5,000.
- Inspections: Standard home inspection $500 to $1,200; specialized inspections (well, septic, oil tank, radon, lead) add $500 to $2,000+ depending on what is needed.
- Prepaid property taxes and insurance: Pro-rated based on closing date and lender requirements.
What the Transfer Tax Change Means for Sellers
The 50/50 split structure means the November 2025 transfer tax change also affects Maine sellers, not just buyers. Sellers of properties above $1M now pay materially more transfer tax at closing than they did before November 2025. On a $5M Maine sale, the seller's share of transfer tax is $26,200, which would have been approximately $11,000 under the old single-tier rate.
For sellers planning to bring a Maine property to market in 2026 and beyond, the transfer tax change is now a meaningful line item on the net proceeds calculation. It does not change the gross sale price, but it does change the net to the seller. This is particularly relevant for multigenerational coastal families considering whether to bring a long-held Kennebunkport, Cape Elizabeth, or Bar Harbor property to market now versus holding.
Exemptions from Maine's Transfer Tax
Certain Maine real estate transfers are exempt from the RETT under 36 M.R.S. § 4641-C. The most common exemptions for residential coastal luxury buyers and sellers include:
- Transfers between spouses
- Transfers between parents and children, grandparents and grandchildren, or siblings (in some configurations)
- Transfers to or from a controlled entity (such as a wholly-owned LLC) by the same beneficial owner
- Transfers by will or intestate succession
- Transfers to a revocable trust by the grantor
Each exemption has specific statutory requirements. Exemption claims must be clearly stated on the Real Estate Transfer Tax Declaration filed with the deed. Maine attorneys handling coastal luxury transactions are familiar with these provisions and will identify applicable exemptions during the closing process. Do not assume an exemption applies without confirming with closing counsel.
The bottom line on Maine taxes: Even after the November 2025 transfer tax change, Maine is still the most favorable closing-cost state on the Northeast coastal luxury map. The combination of a 50/50 split structure, the absence of a New York-style mansion tax, the absence of a Massachusetts-style Land Bank fee, and competitive municipal property tax rates makes Maine the lowest-cost coastal luxury jurisdiction for any property above $1M. The November 2025 change narrowed the advantage but did not eliminate it.
Frequently Asked Questions
What is the real estate transfer tax in Maine in 2026?
Maine charges a Real Estate Transfer Tax of $2.20 for each $500 of property value, split equally between buyer and seller. As of November 1, 2025, an additional $3.80 per $500 applies to the portion of the sale price that exceeds $1,000,000, bringing the rate on the over-$1M portion to $6.00 per $500. On a $2M Maine purchase, the total transfer tax is $16,400, with each side paying $8,200. On a $5M purchase, the total is $52,400, with each side paying $26,200.
Does Maine have a mansion tax?
No. Maine does not have a New York-style mansion tax that imposes a percentage on the full purchase price above a threshold. Maine introduced a transfer tax surcharge on November 1, 2025, that applies only to the portion of a sale price exceeding $1,000,000, not to the full price, and is split 50/50 between buyer and seller. This is structurally different from a mansion tax.
Who pays the transfer tax in Maine, buyer or seller?
Maine's Real Estate Transfer Tax is statutorily split 50/50 between the grantor (seller) and the grantee (buyer) under 36 M.R.S. § 4641-A. This applies to both the base $2.20 per $500 tier and the additional $3.80 per $500 tier for the portion above $1M. The shared structure means the buyer's effective Maine acquisition tax burden is half of the total transfer tax.
What are property tax rates in Kennebunkport and Cape Elizabeth, Maine?
Both Kennebunkport and Cape Elizabeth set their own annual mil rates, expressed as dollars of tax per $1,000 of assessed value. Cape Elizabeth has historically run a slightly higher mil rate than Kennebunkport. On a $4M assessed-value property, annual property taxes typically range from $22,000 to $32,000 in Kennebunkport and $26,000 to $36,000 in Cape Elizabeth as of 2026. Verify the current mil rate and assessment ratio with the specific town assessor before underwriting any property.
Is Maine cheaper to buy real estate in than Massachusetts, New York, or New Jersey?
For coastal luxury properties above $1M, Maine has the lowest buyer-side transfer surcharge of any Northeast coastal state. On a $5M purchase the buyer's Maine transfer tax is $26,200, compared to $112,500 in the Hamptons (NY mansion tax), $100,000 on Nantucket (2% Land Bank), and approximately $0 in Newport (RI has no surcharge). Maine's 50/50 split structure and absence of a mansion tax or Land Bank fee make it the lowest-closing-cost coastal luxury market in the Northeast for any property above $1M.
