The Merrimack Valley School District tax rate decreased from $19.64 in 2019 to $16.39 in 2020. It appears there are a few reasons for this, including an approximate $188,000 decrease in their valuation apportionment, an $867,000 increase in adequacy grants received, and a $38 million increase in assessed values within the Concord MVSD area. The assessment increase was fueled primarily by the increased value of residential property as well as a strong market for apartments.
