If my tax value is reduced, will I have to appeal again every year?

Although the standard tax value has been reduced because it exceeded the maximum limit (for the income year 2016, the tax value should not exceed 30 or 96 percent of the dwellings market value for the orimary and secondary dwellings respectively), the tax value will normally be calculated using the standard residential property formula again in future income years.

To avoid repeatedly having to request a reduction in the tax value every year, a proportionate reduction in the square metre rate is given in the assessments for the next five income years. The square metre rate will then be reduced by as many percentage points as you are able to document that the tax value exceeded the maximum limit by. 

Example:

If you are able to document that the tax value amounts to 40 percent of the primary dwelling's market value and the tax value is therefore reduced to 30 percent of the market value, the square metre rate for the property will automatically be reduced by 25 percent for the next five years.
