Hebesatz before/after the 2025 reform
The Hebesatz rises from 540% to 975% (+80.6%).
The Hebesatz rises by 80.6% — a meaningful share of owners in Hamburg will pay visibly more property tax in 2025 than the year before.
Hamburg describes the reform as revenue-neutral: the city expects no additional total revenue. Individual properties can still shift noticeably — commercial and high-value locations typically pay more, peripheral single-family homes often less.
The binding figure comes from the municipal Grundsteuerbescheid. The underlying Grundsteuerwert and Messbescheid are issued by the tax office (Finanzamt) — challenges against the assessed value must be filed there within one month, not with the city.
