Property Tax Bills Across Merrimack County, New Hampshire
Property tax bills in Merrimack County are calculated by applying the local tax rate to a home’s assessed value, which is based on the market value of the property.

The median home price is $327,300, and tax bills range from the 25th percentile at $5,057 to the 75th percentile at $9,391, with the 90th percentile reaching $12,292. The highest median tax bill is $11,775 in Contoocook, while the lowest is $4,271 in Tilton.
