Property Taxes in Portsmouth
Portsmouth's property tax picture is genuinely mixed relative to New Hampshire's own famously high statewide burden -- the city's own cited effective rate (approximately 1.19%-1.66% across sources) runs at or below the statewide 1.5%-1.85% range, even as its official FY2026 municipal rate ($11.51 per $1,000) applies to the city's genuinely high assessed home values.

Learn moreNew Hampshire's Statewide Rate Is Genuinely Among the Highest Nationally
New Hampshire's real, current statewide effective property tax rate is cited in a roughly 1.5%-1.85% range across sources reviewed this pass, commonly ranked among the nation's top 3-4 highest, with a cited statewide median annual bill around $6,667 on a home valued around $402,500 -- the real tradeoff behind the state's no-income/no-sales-tax structure.
Portsmouth's Own Cited Effective Rate Runs Somewhat More Moderate
Despite New Hampshire's high statewide burden, Portsmouth's own cited effective rate ran approximately 1.19% (a ZIP-03801-specific citation, described as below the state average) to approximately 1.66% (a separate citation) -- this record's primary figure. This record's own reasoned interpretation, not a directly sourced causal claim, is that Portsmouth's genuinely large non-residential tax base (the Pease International Tradeport's 250+ businesses, a dense downtown commercial/tourism corridor) likely helps hold the city's own effective RATE below the statewide average.
The Official FY2026 Municipal Rate Applies to Genuinely High Assessed Values
The City of Portsmouth's official FY2026 property tax rate is $11.51 per $1,000 of assessed valuation -- even at a more moderate effective rate, the DOLLAR AMOUNT owed remains real and substantial given Portsmouth's genuinely high home values (cited in the $678,428-$955,000 range across sources).
Confirm a Specific Address Directly With the City Assessing Department
Given the real, disclosed cross-source spread on Portsmouth's own effective rate, buyers and movers should confirm a specific target property's current assessed value, levy, and any applicable exemptions directly with the City of Portsmouth Assessing Department rather than relying on a citywide average.
