Kennebunk's rate, ratio and tax base
Maine Revenue Services certified Kennebunk's 2024 ratio at 74%: its assessments average 74% of market value, below market, so the $16.95 rate overstates the tax on a dollar of market value. Multiplying the rate by the ratio gives $12.54 per $1,000 of market value at that average level. The state median ratio is 100%, and 234 municipalities are certified at 100%.
The rate comes from the town's own numbers: Kennebunk committed $50,008,188 of property tax on $2,950,335,600 of taxable valuation, and $16.95 per $1,000 on that valuation raises $50,008,188. That commitment ranks 13th of 482 in Maine and is 8.45% of all the property tax committed in York County's 29 municipalities; the valuation ranks 15th.

Appealing a Kennebunk assessment
In Maine an abatement starts with a written request to Kennebunk's assessors within 185 days of the tax being committed. The assessors have 60 days to decide; then the appeal goes within 60 days to the Board of Assessment Review, or to the York County commissioners where the municipality has no board, and on to the Superior Court within 30 days (Maine Revenue Services, Property Tax Bulletin No. 10 (revised March 26, 2020)). Overvaluation is judged against how the town assesses similar property on average, which is where Kennebunk's 74% certified ratio comes in: a $300,000 assessment at that ratio corresponds to about $405,405 of market value.
