Tax Considerations for Bitcoin Estates in Australia

Bitcoin is property for Australian tax purposes. That single classification drives almost everything else: capital gains tax applies on disposal, the cost base resets to market value at the date of death when assets pass through a deceased estate, and in-specie transfers to beneficiaries are generally CGT-free at the estate level. Get those three principles right and most of the rest follows.

The cost base reset is the most important and most misunderstood. When a holder dies, the assets in their estate are taken to be acquired by the legal personal representative at the market value on the date of death. For long-held Bitcoin with a low cost base, this is a significant uplift - and it means a beneficiary who later sells is calculating their gain from the date-of-death price, not the deceased's original purchase price. Documenting the date-of-death AUD value of the holdings is therefore a critical executor task; spot price snapshots from a reputable Australian exchange, recorded with timestamp evidence, are the standard.

In-specie transfer to beneficiaries - moving the Bitcoin itself to the beneficiary's wallet rather than selling it inside the estate - is generally the cleanest path. No CGT event occurs at the estate level, the beneficiary inherits the date-of-death cost base, and the beneficiary becomes responsible for any tax consequences of their own future disposal. This is almost always preferable to liquidating inside the estate, which can crystallise CGT and create a tax bill the beneficiaries then have to fund.

There are situations where liquidation is unavoidable - for example, where the will requires a cash distribution, where beneficiaries cannot or will not take custody of digital assets, or where the estate has insufficient liquid assets to cover other obligations. In those cases, the timing of the disposal matters: gains are calculated against the date-of-death cost base, and any movement in price between death and disposal is a taxable event for the estate.

A few traps to avoid. First, do not assume an exchange account balance equals the holdings - cold storage holdings are usually larger and need separate valuation. Second, do not value Bitcoin in USD and convert later; use AUD values directly from an Australian exchange, with timestamps. Third, do not transfer to beneficiaries before resolving testamentary disputes - once the asset has moved on-chain, undoing it requires the beneficiary's voluntary cooperation.

None of this is tax advice. It's a map of the territory. Get a tax adviser who has worked on a digital asset estate before - they exist, and the difference in outcome versus a generalist is significant.
