HOMEOWNERS can assess what their likely property tax will be using an online guide.

Calculate property tax estimate here

The service provides a guide to average market values of properties in a given locality and offers an indicative valuation band for properties depending on type, age and location. It does not provide market values for individual properties. The guidance is primarily based on the market value of properties sold since the year 2010 in the area, adjusted for average price movements in the interim.

This guidance will be helpful in the majority of cases but there are always properties in an area that differ from the average.

Self assessment requires property owners to honestly assess the market value of their own property. If a property is smaller or larger than the average for the area, is in a significantly poor state of repair or has exceptional or unique features, this will have to be factored into the assessment of the valuation.
