Search AgainRefund Details
Refund totals include those the county has paid and those it estimates it will pay in the future for challenges filed since the 2011-12 tax year. This data is current through mid-2016.
Property Value Details
A property’s assessment is a fraction (.25%) of what the county estimates it is worth — its “full market value” — but since officials have not updated their “frozen” estimates since 2012-13, most properties have become assessed below what they are worth as real estate prices have risen. Appealed properties, though, are assessed even lower.
Factors Details
Exemption change indicates whether exemptions (like STAR for school taxes) changed, affecting the assessment by 10 percent or more than if they had not changed.
Recent STAR Exemption
Properties like this one that more recently obtained STAR property tax exemptions receive a STAR credit check from the state instead of having their tax bills reduced by the exemption. Due to data limitations, STAR credit check amounts are not subtracted from the above tax totals for 2017-18. As a result, those totals are larger than the actual tax burden of property owners who received a check.
