Bath's rate, ratio and tax base
Maine Revenue Services certified Bath's 2024 ratio at 100%: its assessments average 100% of market value, exactly at market. Multiplying the rate by the ratio gives $16.50 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: Bath committed $27,858,071 of property tax on $1,688,367,927 of taxable valuation, and $16.50 per $1,000 on that valuation raises $27,858,071. That commitment ranks 25th of 482 in Maine and is 28.76% of all the property tax committed in Sagadahoc County's 10 municipalities; the valuation ranks 33rd.

|---|---|---|
| $200,000 | $3,300.00 | +$388.00 |

Each bill is the assessed value divided by 1,000 and multiplied by $16.50, 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 Bath assessment
In Maine an abatement starts with a written request to Bath'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 Sagadahoc 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 Bath's 100% certified ratio comes in: a $300,000 assessment at that ratio corresponds to about $300,000 of market value.
