The city has released fiscal 2016 property value assessments, and there are some reports of Jamaica Plain property taxes leaping significantly from the year before. The residential tax rate in Boston for 2016 dropped to $11.00 per thousand, down from $12.11 the year before. The residential exemption increased to $1,960.00, from $1,879.53. But that doesn't stop property taxes from increasing if assessments rise quickly. Assessments can be viewed on the city assessor's website.
