Calculating the adjusted cost base (ACB) for a property sale is a crucial step in determining your capital gains tax (CGT) liability. The ACB is essentially the cost of acquiring and holding the property, adjusted for certain factors. It includes the original purchase price, plus any capital improvements made, less any depreciation claimed under Division 40 and Division 43 of ITAA 1997.
The most common misconception is that only the purchase price impacts the ACB. However, substantial changes can occur through capital improvements and depreciation. Under Division 43, capital works expenditures can increase the ACB, while depreciation claimed can decrease it. This careful balance is essential for accurate CGT calculations.
Take a practical example: Imagine you purchased a 2-bedroom apartment in Sydney in 2010 for $700,000. Over the years, you've added a new kitchen costing $50,000 and claimed $20,000 in depreciation for plant and equipment. Your adjusted cost base would be $730,000 (purchase price plus kitchen improvement minus depreciation). If you sell the property for $1,000,000, your capital gain would be $270,000.
In our experience reviewing thousands of properties across Australia, many investors overlook the impact of capital improvements. They often fail to keep detailed records, which are essential for accurate calculations. Another frequent oversight is not adjusting for depreciation already claimed, leading to incorrect CGT calculations. Investors also tend to forget incidental costs like legal fees and stamp duty, which can be added to the ACB.
The answer can differ depending on your situation. If you acquired the property before 1985, it is exempt from CGT. For properties acquired after 9 May 2017, certain depreciation rules apply. If the property is held within a self-managed super fund (SMSF), different tax implications might arise. Joint ownership necessitates splitting the ACB calculations according to ownership percentage.
Given the complexities involved, it's wise to seek professional advice. A Chartered Quantity Surveyor can provide a detailed breakdown of your property's cost base, ensuring no detail is overlooked. Working alongside your accountant, you can optimise your tax position and avoid costly errors.
