Cryptocurrency in retirement: tax, Centrelink, and the estate planning challenge

Cryptocurrency holdings are increasingly common among Australians of all ages, including retirees. The tax and Centrelink treatment of these assets is well established, if not always intuitive. The estate planning dimension is genuinely distinctive — without specific arrangements, cryptocurrency can be permanently and irreversibly lost when the holder dies. For any retiree with material cryptocurrency holdings, understanding all three dimensions is important.

How is cryptocurrency taxed in retirement?

The Australian Taxation Office treats cryptocurrency as property for capital gains tax purposes — not as currency (ato.gov.au). This means every disposal triggers a CGT event. A disposal includes selling cryptocurrency for Australian dollars, exchanging one cryptocurrency for another, and using cryptocurrency to purchase goods or services. The cost base of the holding is established at the point of acquisition and any gain or loss at disposal is calculated against that base. For assets held longer than 12 months, the 50% CGT discount reduces the taxable gain for individual taxpayers (Income Tax Assessment Act 1997, s.115-10). One disposal that holders frequently miss is the crypto-for-crypto trade — each exchange of one digital asset for another is a disposal of the first asset at its market value at the time of the trade, potentially triggering CGT even though no Australian dollars were received.

There is a personal use asset exemption under ITAA 1997 s.118-10 that can in theory apply to cryptocurrency — if the holding was acquired and used solely for personal use and enjoyment, and cost $10,000 or less, it may be exempt from CGT. In practice, this exemption applies very rarely to cryptocurrency: the ATO's position is that most cryptocurrency is acquired and held for investment or speculative purposes, and the $10,000 cost threshold makes it unavailable for most significant holdings. Cryptocurrency received as income — from staking rewards, mining, or as payment for services — is generally assessable as ordinary income at the time of receipt at market value. If that same holding is later sold, a further CGT event occurs on any gain or loss from the income-assessment date.

For retirees, the record-keeping challenge is real. Every transaction — every buy, every sell, every exchange, every transfer between wallets — needs to be captured with dates, market values, and cost-base information. Crypto tax software can assist, but the underlying records remain the holder's responsibility.

How does Centrelink treat cryptocurrency for the Age Pension?

For Age Pension purposes, cryptocurrency is treated as a financial investment. Under the assets test, holdings are assessed at market value as at the date of assessment, and any substantial holdings will count toward the assets-test threshold. For the income test, the Social Security Act subjects financial investments to deeming — the same deeming rates that apply to bank accounts and shares (1.25% on the first $103,800 for singles and 3.25% above that, as of 20 March 2026, per DSS Guide 4.4.1.10) apply to the market value of cryptocurrency holdings. Actual realised gains do not generate additional income test obligations separately — the deeming replaces the income test calculation, just as it does for other financial assets.

The compliance point is disclosure. Cryptocurrency holdings must be reported to Services Australia and updated when the value changes materially. The ATO runs a data matching program that collects transaction data from Australian cryptocurrency exchanges, and ATO data sharing with Services Australia means undisclosed holdings carry compliance risk. Holdings that are undisclosed can generate Centrelink debt when identified retrospectively.

What is the estate planning challenge with cryptocurrency?

Cryptocurrency presents a genuinely distinctive estate planning problem that does not arise with bank accounts, super, or shares. Access to a self-custodied cryptocurrency holding requires the private key or seed phrase associated with the wallet. There is no institution, no registry, and no legal process that can override this — if the private key is lost, the holdings are permanently inaccessible, regardless of what a will says or what a probate court orders. This is not a hypothetical risk: a meaningful proportion of all cryptocurrency ever created is believed to be permanently inaccessible because private keys were lost with their holders.

For a retiree who holds cryptocurrency in self-custody — hardware wallets, software wallets, or paper wallets — the estate implications are direct: unless the private key or seed phrase is documented in a form that family or the executor can eventually find and use, the holdings will be lost. The documentation must be secured (a will is a public document after probate; seed phrases in a will are accessible to the world) but ultimately accessible to the right person at the right time. Common approaches include sealed instructions held with a solicitor, a separate document stored securely alongside the will, or a trusted family member with specific instructions.

For cryptocurrency held through an exchange, the family or executor needs the account credentials and may need to navigate the exchange's estate administration process — which varies by platform and is not uniformly straightforward. Some exchanges have failed historically, adding counterparty risk to the picture.

Inclusion in probate also requires identification and valuation at the date of death, which can be challenging for volatile assets. Specialist digital asset estate administration services exist for complex situations.

What security risks emerge for retirees managing cryptocurrency?

Self-custody of cryptocurrency — managing private keys, maintaining secure backups, navigating hardware wallets — requires sustained technical engagement. For retirees in their sixties and seventies who are comfortable with the technology, self-custody may be appropriate. As cognitive function changes or engagement with technology reduces, the operational demands of self-custody can become a genuine practical risk: misplaced seed phrases, forgotten PINs, and inaccessible wallets are common failure modes. A deliberate simplification toward exchange custody as retirement progresses — analogous to the simplification trajectory in investment portfolios discussed in other articles in this series — is pragmatic for many retirees. Exchange custody carries counterparty risk, but for most older retirees the more pressing risk is permanent loss through inaccessible self-custodied holdings.

How does cryptocurrency volatility affect retirement income planning?

Cryptocurrency is substantially more volatile than traditional asset classes. Losses of 50% or more over short periods have been common historically, and the sequence-of-returns risk that applies to all growth assets is amplified for crypto. For a retiree drawing down income from a portfolio, selling crypto in a depressed market to meet living costs locks in losses in a way that can be difficult to recover from. For most retirees, cryptocurrency as a modest allocation within a diversified portfolio — rather than a material concentration — is more consistent with retirement income objectives. The specific proportion depends on individual circumstances, but large concentrations in a single volatile asset are generally not aligned with the income stability that retirement requires.

What steps should retirees with cryptocurrency take now?

The most important actions for a retiree with material cryptocurrency are: ensuring records are complete (every transaction, every cost base, every exchange); disclosing holdings to Services Australia accurately and keeping disclosures current; arranging estate documentation so the holdings can be located and accessed after death; reviewing the custody arrangement to assess whether self-custody remains appropriate; and seeking specialist tax advice if the transaction history is complex or capital gains are material. For holdings that are genuinely small and simple, the self-managed approach may be adequate. For material holdings, specialist crypto-aware tax advice and specific estate planning with a digital asset-literate solicitor are typically worthwhile.
