Zillow gets their information from public databases.
You need to go to the city/town/county/state website and look for the property tax records.
Normally there are two values:
- the assessed value of the structure and property (some jurisdictions split this out)
- and the tax rate. It may be expressed at $x.xx per $100.
In some jurisdictions there are several twists:
- some only update the assessment every x years. So you need to see when was the last/next assessment.
- some limit the maximum percentage change between assessments. They will specify what the assessment would be if this limiting factor wasn't included.
- some fix the assessed value at some date in the past or when the home is first constructed, or when it was last sold. This should be noted. These jurisdictions adjust the percentage to reflect the impact of inflation.
If they are using one of these twists they will note that there can be a large change in assessed value when the property is sold.
The local government website will also specify if there are other "taxes" that are added to your tax bill. This can include: storm water management, gypsy moth...
In some cases there are piggy back taxes: the town can be part of a county and both tax you.
based on the numbers in your question the property is assessed at 24K with a ~$7.92 per $100 rate.
