Methodology and attribution
Statewide effective rates come from 2024 ACS owner-occupied housing data as compiled in the Tax Foundation 2026 state rankings. NMC models estimates from that source; we did not originate the ACS microdata.
County effective rates are calculated as median real estate taxes paid (ACS table B25103) divided by median owner-occupied home value (ACS table B25077) for the 2020–2024 ACS 5-year release. Because both inputs are medians for the same county, the ratio is an approximation of the county effective rate rather than an aggregate of individual bills. Counties are excluded when either median is suppressed by the Census Bureau or when the county has fewer than 500 owner-occupied housing units, where ACS medians carry wide margins of error.
Rankings and research tables that show a dollar tax apply the statewide or county effective rate to a user-selected home value with a 100% assessment ratio and no exemptions, unless a tool explicitly lets the user change those inputs.
Estimates are for planning only. Actual bills vary by assessed value, taxing districts, special assessments, reassessment rules, and local law. This is not tax, legal, or financial advice and is not an official assessor tool.
