You must not seek to increase the value of property where any of the following apply

  • any of the bars to assessment of additional tax set out (IHTM30401)
  • an agreement on value (IHTM30442), or
  • a formal notice of determination (IHTM37001) of the value of land.We may however be able to reopen the valuation of property if, since our acceptance or agreement of the valuation, we have received information indicating

  • that the property to be valued needs to be redefined (IHTM30432) or
  • that the valuation was based on wrong or misleading information.Refer any such case to your manager.
