Which Renovation Costs Are Deductible vs Capital?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

In Australia, renovation costs can be either immediately deductible or capital in nature. Immediate deductions include repairs that restore an asset to its original condition. Capital costs, such as structural improvements, must be depreciated over time under Division 43. Consult your accountant for specifics.

Renovating an investment property can boost its value and rental income, but it’s crucial to understand which costs you can claim immediately and which need to be capitalised. Misclassifying these can affect your tax position.

Understanding Deductible vs Capital Renovation Costs

Immediate deductions are typically available for repairs and maintenance that restore an asset to its original condition. This includes fixing a broken window or repainting a wall. These expenses are claimed in the year they are incurred and can be deducted from your rental income, reducing your taxable income for that year. On the other hand, capital costs are those that improve the property beyond its original state, such as adding a new room or replacing an entire roof. These costs are not immediately deductible but can be claimed over time through capital works deductions under Division 43 of the ITAA 1997.

A common misconception is that all renovation expenses can be immediately claimed. However, improvements that enhance the property's value are considered capital in nature and must be depreciated over their effective life.

How This Works in Practice

Consider a 1980s-built 3-bedroom house in Melbourne purchased for $800,000. If you spend $10,000 on painting and fixing broken tiles, these are immediate deductions. Assuming a 37% tax rate, this results in a tax saving of $3,700 in the year the expenses are incurred.

In contrast, if you spend $50,000 adding a new bathroom, this is a capital expense. Under Division 43, you could claim 2.5% per annum as a capital works deduction, equating to $1,250 annually, reducing your taxable income incrementally over the effective life of the improvement.

Professional Insight

In our experience, investors often overlook the importance of distinguishing between repairs and improvements. One thing we frequently see is clients assuming all renovation costs are immediately deductible, leading to unexpected tax adjustments. Investors also miss out on claiming depreciation on capital improvements, which can significantly enhance cash flow over time. What most investors don't realise is that keeping detailed records and invoices can simplify the process of claiming deductions and maximise their benefits.

When Does the Answer Change?

  • Properties Acquired Pre-1985: For properties built before 16 September 1987, capital works deductions may not be available.
  • Post-9 May 2017 Acquisitions: If you acquired a second-hand residential property after this date, you cannot claim Division 40 deductions on existing plant and equipment.
  • Commercial Properties: Different rules apply, and immediate deductions may be available for some capital improvements.
  • Partial Year Ownership: If you purchase a property part-way through the year, you may only claim a portion of the annual depreciation.
  • When Should You Seek Professional Advice?

    Determining whether a cost is deductible or capital can be complex, and it often depends on the specifics of the renovation and the property's history. Consulting a Chartered Quantity Surveyor can help ensure you’re claiming the maximum deductions available. An accountant can provide guidance on how these deductions fit into your overall tax strategy.
