What the Hamilton County numbers mean
A median is the middle household: half of owner-occupied households in Hamilton County pay more than $3,340, and half pay less. Your own bill is set by your home's assessed value, the exemptions you qualify for, and the local taxing districts your property sits in — so individual bills vary widely around the median.
Dividing the median tax by the median home value gives a derived effective rate of 0.88% for Hamilton County. It is an estimate built from two survey medians, not the county's official rate, but it is a fair way to compare the local tax burden with other counties where home values are very different.

How the tax is worked out
As an illustration of the arithmetic: at Hamilton County's derived rate of 0.88%, a home valued at $400,000 would carry a tax bill of roughly $3,524 a year. That is only an illustration using the derived rate — a real bill is computed from the property's assessed value, its exemptions, and the combined rates of its specific taxing districts, so it can be higher or lower.
The usual sequence is: the local assessor values the property; exemptions are applied; the taxable value is multiplied by the combined local rates; and the county bills and collects the tax, distributing it to the schools, municipalities and districts that levied it.
Checking your assessment in Hamilton County
Most successful appeals are won on facts, not arguments. Start with the property record card held by the Hamilton County assessor: wrong square footage, an extra room, or a missing homestead exemption are common and fixable. Next, line your assessed value up against recent sales of genuinely similar homes nearby. Many disputes end at an informal conversation with the assessor's office; if yours does not, file the formal appeal with the review board named on your notice before its deadline, evidence attached, and keep paying the bill in the meantime so penalties do not build up.
