Naples's rate, ratio and tax base
Maine Revenue Services certified Naples's 2024 ratio at 100%: its assessments average 100% of market value, exactly at market. Multiplying the rate by the ratio gives $9.30 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: Naples committed $12,824,527 of property tax on $1,378,981,361 of taxable valuation, and $9.30 per $1,000 on that valuation raises $12,824,527. That commitment ranks 56th of 482 in Maine and is 1.29% of all the property tax committed in Cumberland County's 28 municipalities; the valuation ranks 41st.

Each bill is the assessed value divided by 1,000 and multiplied by $9.30, before exemptions, credits such as Maine's homestead exemption or special charges. These are assessed values, not sale prices: at a 100% ratio the $300,000 row is a property worth about $300,000. The last column is the difference from the same assessment at the $14.56 per $1,000 state median.

Appealing a Naples assessment
In Maine an abatement starts with a written request to Naples'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 Cumberland 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 Naples's 100% certified ratio comes in: a $300,000 assessment at that ratio corresponds to about $300,000 of market value.
