Trading stock is any property a business owns, that they intend to sell or exchange. 

These are examples of trading stock:

  • anything that is produced or manufactured to be resold
  • partly completed work that would be trading stock if completed
  • materials kept to produce or manufacture trading stock.

The following items are not trading stock:

  • assets that have been depreciated
  • consumable aids (items that are used in the manufacturing process, but do not form part of the finished product)
  • spare parts not held for resale
  • land
  • financial arrangements.

Taxing trading stock

The opening value of trading stock in an income year is deductible, and the closing value of trading stock in the income year is assessable.

The opening value of trading stock in a year must generally be the same as the closing value of the previous year.

Valuing trading stock

If your business owns trading stock, you must value it at the end of each income year.
