This tax is payable at the time your deed is registered. Just enter the purchase price and click on 'calculate' to see the tax payable.
BUT KEEP READING, THE NEWS IS GOOD, FOR NOW!!
If you have not owned property before (either by yourself or with one/more people), you do not have to pay the tax!!
If you have owned property before but are purchasing property with someone who hasn't owned property before, only a portion of the tax is payable!!
