Maine's average effective property tax rate is right around the ~0.99% national average — estimates from reputable sources cluster between 0.98% and 1.10% depending on year and methodology (Tax Foundation puts owner-occupied effective rate at 0.98%; SmartAsset's calculator shows 0.91%–1.02% depending on the data year used; several aggregators put the statewide average near 1.09%–1.10%). Practically speaking, Maine is essentially at the national norm overall, but this masks large regional variation: populous, high-value coastal/southern counties like Cumberland pay effective rates and dollar bills far above the state average (median bill near $4,500–$4,900/year), while rural northern counties like Aroostook pay dramatically less (median bill around $1,700/year). Maine relies unusually heavily on property tax as a revenue source — about 36% of state and local tax revenue comes from property taxes, one of the higher shares in the country — which is why local rates in property-tax-dependent towns can run well above the state average even though the statewide effective rate looks close to typical.
Example: Depending on the data source and year, Maine's statewide median annual property tax bill is reported in the roughly $2,600–$3,600 range. Tax Foundation/Census-based estimates put the median near $2,598–$3,036 (on median home values of roughly $236,600–$296,600), while SmartAsset's more recent calculator (using a higher statewide median home value of about $341,900) shows a median tax bill of about $3,103. A concrete county-level example: a median-value home in Cumberland County (Maine's most populous and highest-cost county, includes Portland) carries a typical annual tax bill of roughly $4,500–$4,900, versus roughly $1,700 in rural Aroostook County — illustrating just how much the "median" varies by where in Maine you look.
Figures vary meaningfully by source because of differing data vintages (some sites cite older Census ACS 5-year estimates, others use current-year assessed values) and differing definitions (effective rate on assessed value vs. market value vs. owner-occupied only). For this reason, several of the "2026" statistics sites surfaced in search (e.g., propertytaxrates.org, taxbycounty.com, plainpropertytax.com, statecalc.com) appear to be low-authority, likely auto-generated aggregator content with inconsistent numbers — treat these as directional only. For authoritative, current figures, rely on Maine Revenue Services (maine.gov/revenue) for exemption rules/amounts and Tax Foundation for comparative effective rates; practical tip: because Maine's homestead exemption is scaled by each municipality's certified assessment ratio (except for the 65+/veteran carve-out starting April 2026), the actual dollar savings from the $25,000 exemption differs town to town — homeowners should confirm their specific municipality's ratio with the local assessor.
