What is Cost Base?

The cost base of an asset is its original purchase price plus any acquisition costs, improvements and other allowable amounts. It is used to calculate capital gains or losses on disposal.

The cost base is the foundation for calculating capital gains tax when you dispose of an asset. It includes: the original purchase price, acquisition costs (like legal fees, stamp duty and brokerage), capital improvements made during ownership, costs of ownership that are not tax-deductible (like certain interest in some jurisdictions) and costs relating to the disposal (like legal and agent fees). Maintaining accurate cost base records from the date of acquisition is essential because you may not sell the asset for many years. Without proper records, you may not be able to substantiate a higher cost base, resulting in a larger taxable capital gain. For depreciable assets, the cost base is reduced by the depreciation deductions claimed over the asset's life. SortBooks helps maintain cost base records by correctly categorising asset purchases, improvements and disposal costs in Xero, creating a reliable historical record for future CGT calculations.
