Depreciating assets

There are special rules to work out the decline in value of certain depreciating assets.

Last updated 22 August 2025

A depreciating asset is an asset that has a limited effective life and can reasonably be expected to decline in value (depreciate) over the time it is used. Some assets, such as land and trading stock, are not depreciating assets.

The general depreciation principles apply to most depreciating assets used in primary production. However, the deduction for the following primary production depreciating assets is worked out using special rules for:

For more information, see Guide to depreciating assets.

Water facilities

As a primary producer or irrigation water provider, you can claim an immediate deduction for certain expenses you incur primarily and principally for conserving or conveying water for use in a primary production business on land in Australia. You can claim the deduction even if you are only a lessee of the land.

A water facility includes plant or a structural improvement, or an alteration, addition or extension to plant or a structural improvement, that is primarily and principally for the purpose of conserving or conveying water.

Water facilities include:

  • dams
  • tanks
  • bores
  • irrigation channels
  • pumps
  • water towers
  • windmills.

No deduction is available for expenses incurred on acquiring a second-hand commercial water facility unless you can show that no-one else has deducted or could deduct an amount of the earlier expense on the construction or previous acquisition of the water facility.

See Water facilities for definitions and how to claim deductions.

Fencing

As a primary producer you can claim an immediate deduction for the cost of fencing you incur primarily and principally for use in a primary production business on land in Australia. You can claim the deduction even if you are only a lessee of the land.

See Fencing and fodder storage assets for definitions and how to claim deductions.

Fodder storage assets

You can claim a deduction for the full cost of a fodder storage asset, if you:

  • incurred the expense
  • mainly use it to store fodder
  • use it in a primary production business on land in Australia – even if you are only a lessee of the land.

Claim the deduction through your tax return in the year you incurred the expense.

Fodder storage assets include:

  • silos
  • liquid feed supplement storage tanks
  • bins for storing dried grain
  • hay sheds
  • grain storage sheds
  • above-ground bunkers.

See Fencing and fodder storage assets for definitions and how to claim deductions.

Horticultural plants

A horticultural plant is a live plant or fungus that is cultivated or propagated for any of its products or parts.

You can claim a deduction for the depreciation of horticultural plants, provided:

  • you own the plants (lessees and licensees of land are treated as if they own the horticultural plants on that land)
  • you use the plants in a business of horticulture to produce assessable income

Your deduction for the depreciation of horticultural plants is based on the expense incurred in establishing the plants. This does not include the cost of purchasing or leasing land, or expenses on draining swamp or low-lying land or on clearing the land. It would include, for example:

  • the costs of acquiring and planting the seeds
  • part of the cost of ploughing, contouring, fertilising, stone removal and topsoil enhancement relating to the planting.

You can't claim this deduction for trees used in carbon sink forests.

For more information, see Calculating the decline in value of horticultural plants.

Grapevines

If you planted and first used grapevines in your primary production business, the depreciation of the grapevines is worked out under the general rules relating to horticultural plants.

For more information, see Calculating the decline in value of grapevines.

 

Deductions for investing in water facilities can be claimed by primary producers and irrigation water providers.

Primary producers can claim an immediate deduction for capital expenses on fencing and fodder storage assets.

You can claim a deduction for the decline in value of horticultural plants you own and use in a horticulture business.
