How Does Depreciation Work for a Data Centre?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Depreciation in data centres involves claiming deductions for the decline in value of assets under Division 40 (plant and equipment) and Division 43 (capital works) of ITAA 1997. Plant and equipment include items like servers and cooling systems, while capital works cover structural improvements. Properly claiming these can significantly reduce taxable income.

Depreciation for data centres is a critical consideration for investors and commercial property owners. It involves claiming deductions for the decline in value of both the building structure and the equipment used within. This can result in substantial tax savings over time.

Under Division 40 of ITAA 1997, you can claim depreciation on plant and equipment such as servers, HVAC systems, and cabling. These items have varying effective lives; for example, the ATO might assign an effective life of 4–8 years for servers and 10–15 years for air conditioning systems. It's vital to note that the 2017 budget changes affecting second-hand residential properties do not apply here, allowing full claims on second-hand equipment in commercial settings.

Division 43 of ITAA 1997 covers capital works. For data centres, this includes the structural elements like walls, floors, and ceilings. Buildings constructed or renovated post-1987 can generally claim a 2.5% annual deduction over 40 years.

A common misconception is that all IT equipment must be depreciated over the same period. However, items have different effective lives, and understanding these differences can maximise your depreciation claims.

Take a practical example of a data centre in North Sydney, purchased for $10 million. The plant and equipment, including servers and cooling systems, are valued at $2 million. Under Division 40, assuming an average effective life of 5 years for these assets, you can claim $400,000 annually in depreciation. For the building, valued at $8 million, you can claim $200,000 annually under Division 43. If your marginal tax rate is 30%, these deductions can reduce your tax bill by $180,000 in the first year.

In our experience reviewing thousands of properties across Australia, we find many investors overlook the full range of depreciable assets in a data centre. Often, they miss claiming on items like specialised cabling or under-floor air distribution systems. It's also common to misclassify assets, leading to incorrect depreciation rates. Ensuring a detailed asset register and engaging a qualified Quantity Surveyor can uncover these opportunities.

The answer can differ depending on your situation. For example, if your data centre includes leased equipment, the ownership of the assets determines who claims the depreciation. For pre-1987 buildings, the capital works deductions might not apply unless significant renovations have occurred. Owners in a joint venture must apportion claims correctly, and those using a Self-Managed Super Fund (SMSF) must consider the fund's tax position.

When it comes to depreciation, professional advice is invaluable. Each data centre is unique, and factors like acquisition date, asset condition, and ownership structure significantly impact your depreciation strategy. Collaborating with a Chartered Quantity Surveyor and your accountant ensures you maximise claims while staying compliant.

  • Review your data centre's asset register for completeness.
  • Confirm the effective lives of each asset with a professional.
  • Ensure your accountant applies the correct Division 40 and 43 deductions.
  • Consider a depreciation schedule from a Chartered Quantity Surveyor.
  • Check for any structural improvements eligible under Division 43.
  • Monitor legislative changes affecting commercial property depreciation.
  • Frequently Asked Questions

    Can I claim depreciation on second-hand equipment in a data centre?

    Yes, in commercial properties like data centres, you can claim depreciation on second-hand equipment under Division 40, unlike residential properties where restrictions apply.

    How does equipment leasing affect depreciation claims?

    If equipment is leased, the lessor typically claims the depreciation. It's crucial to review the lease terms to determine who holds the right to claim.

    Are there state-specific rules for data centre depreciation?

    While federal tax laws govern depreciation, state-specific incentives or grants may affect your overall tax strategy. It's wise to consult a local tax professional.

    How do I report depreciation on my tax return?

    Depreciation is reported in your business's tax return as a deduction. It's essential to maintain accurate records and possibly include a depreciation schedule.

    Does renovating a data centre affect depreciation claims?

    Yes, renovations can create additional depreciable assets under Division 43. Ensure these improvements are added to your asset register for maximised claims.
