Crypto Inheritance and Estate Planning in Australia

Why Crypto Estate Planning is Different

Inheriting a traditional asset like a house or share portfolio is administratively straightforward: the executor contacts the bank or broker, provides probate documentation, and the assets are transferred. Cryptocurrency inheritance is fundamentally different. Crypto held in self-custody is inaccessible without the private keys or seed phrase. There is no bank to contact, no customer service line, no account recovery process. If the deceased held their crypto on a hardware wallet and did not leave documented access credentials, that crypto is permanently lost.

The not your keys not your crypto principle, which describes the security benefit of self-custody, becomes a liability in the estate context if no estate plan exists. Every Australian crypto investor who holds meaningful value in self-custody has an obligation to plan for what happens to that value after their death, for the benefit of their estate and their beneficiaries.

This guide covers the tax treatment of inherited crypto, the practical steps for estate planning, the security mechanisms for ensuring access, and the legal documentation required. The legal risks of crypto investing in Australia and the ATO crypto rules provide the regulatory context.

ATO Tax Treatment of Inherited Crypto

The ATO crypto rules for inherited assets follow the general capital gains tax provisions for inherited assets under the Income Tax Assessment Act 1997. The key rules are:

Death Does Not Trigger a CGT Event

The transfer of a cryptocurrency asset from a deceased estate to a beneficiary is generally not a CGT event for the deceased or the estate. The asset passes to the beneficiary, who inherits the cost base and acquisition date of the deceased. This means the beneficiary steps into the shoes of the deceased for CGT purposes: they are treated as having acquired the asset on the date the deceased acquired it, at the deceased cost base.

This is a significant benefit. If the deceased held Bitcoin for five years with a low cost base and large unrealised gain, that gain is not triggered on death: it rolls over to the beneficiary who can choose when to eventually sell, and who benefits from the 12-month CGT discount for assets the deceased held for more than 12 months (the holding period of the deceased counts toward the 12-month threshold).

Pre-CGT Assets

Crypto assets are all post-CGT assets (the CGT regime started in 1985, well before cryptocurrency existed). The pre-CGT asset exemption that applies to assets acquired before 20 September 1985 does not apply to any cryptocurrency.

Exceptions to the Rollover

The CGT rollover on death does not apply if the crypto passes to a tax-exempt entity (such as a charity) or to a non-resident beneficiary. In these cases, a CGT event may be triggered at the date of death, with the estate potentially liable for tax. The donating crypto to charities context is different to inheritance: a bequest to a charity triggers different rules than an inter vivos donation. A specialist tax agent should be consulted on bequests to charities or foreign beneficiaries.

Including Crypto in Your Will

A cryptocurrency holding must be identified in your will to be properly dealt with in the estate. A generic clause leaving all assets to a beneficiary is legally sufficient to include crypto (since crypto is property), but without specific identification of the crypto assets, the executor may not know what crypto exists or how to access it.

Best practice is to include a specific clause in your will that identifies the crypto holdings (by asset type, approximate quantity, and the wallet or exchange where held), names an executor who is technically capable of managing the transfer, and refers to a separate documented access guide (not included in the will itself, since the will becomes a public document on probate).

The access guide should be a secure document that lists the wallets, exchanges, and access credentials (seed phrases, hardware wallet PINs, exchange login details) needed to access all crypto holdings. This document should be stored securely and its location disclosed only to the executor and trusted family members. The will references the existence of the access guide; the access guide contains the actual credentials. This structure protects the credentials from public disclosure (the will) while ensuring the executor can access them.

Executor Selection

Selecting an executor who is technically competent to manage crypto assets is important. An executor who does not understand hardware wallets, seed phrases, or crypto exchanges may struggle to transfer the crypto correctly. Options include: naming a family member or trusted friend with technical competence, naming a professional executor with crypto capability, or naming co-executors where one handles the crypto assets and one handles traditional assets.

For large crypto estates, a specialist crypto estate service or a lawyer with crypto experience can act as executor or support the lay executor. The multisig wallet structure (discussed below) can reduce the technical burden on the executor by distributing the signing authority across multiple trusted parties.

Secure Access Mechanisms for Estate Planning

The technical challenge of crypto inheritance is ensuring that the executor can access the crypto after the holder dies, without compromising the security of the crypto while the holder is alive. Several mechanisms address this:

Documented Seed Phrases

The most straightforward approach is a documented seed phrase stored securely with estate planning documents. The 12 or 24-word recovery phrase for each hardware wallet is written down on paper (or engraved on metal for durability) and stored in a fireproof safe, safety deposit box, or with a lawyer. The location is disclosed to the executor in the will or access guide.

The risk is that anyone who finds the seed phrase can access the crypto. Mitigations include: splitting the seed phrase across two locations that must be combined, using a passphrase (25th word) that is stored separately from the seed phrase, and limiting knowledge of the location to the executor and a backup. The cold storage setup guide covers the technical security of seed phrase documentation.

Multisig Wallets

A multisig wallet (multi-signature wallet) requires multiple private keys to authorise a transaction. A 2-of-3 multisig, for example, requires any 2 of 3 specified keys to sign a transaction. The estate planning application is to distribute the three keys between the holder (who can access the funds alone while alive), a trusted family member, and a lawyer or estate professional. On death, the two remaining key holders can access the funds together.

This structure provides both security during life (the holder holds one key and can transact normally with one of the other two key holders, but a single thief cannot steal the funds with only one key) and access after death (the two remaining key holders can execute the transfer without needing to find the deceased key). Multisig is more complex to set up but is the most robust technical solution for large crypto estates.

Exchange-Held Crypto

Crypto held on exchanges is somewhat easier for estates to access: the executor contacts the exchange, provides death certificate and probate documentation, and the exchange transfers the funds to the estate. The risks of keeping crypto on an exchange and the crypto exchange bankruptcy guide highlight that exchange-held crypto has counterparty risk that self-custodied crypto does not. The estate planning benefit of exchange custody (easier access for executors) must be weighed against the risk that the exchange may fail before the estate is administered.

SMSF Crypto and Estate Planning

Crypto held within a Self-Managed Super Fund is subject to the superannuation estate planning framework, which is separate from the general estate planning framework. SMSF assets do not automatically form part of the deceased estate: they are distributed according to the binding death benefit nomination and the superannuation trust deed, not the will.

For SMSF trustees who hold crypto in the fund, the crypto SMSF guide covers the trustee obligations including the documentation of access procedures. A binding death benefit nomination directs the super fund to pay the death benefit to specific beneficiaries (spouse, children, or estate). The SMSF trust deed governs how the fund is managed after a trustee member dies, and the remaining trustees (or a new trustee appointed under the deed) continue to manage the fund including the crypto holdings until distributions are made.

The tax treatment of SMSF death benefits depends on who receives them and whether they are paid as a lump sum or income stream. Death benefits paid to tax dependants (spouse, children under 18) are generally tax-free. Death benefits paid to non-dependants (adult children) from taxable components attract tax at 17% (taxed element) or 32% (untaxed element). The SMSF crypto guide and a specialist SMSF adviser should be consulted for the specific planning.

Practical Steps for a Crypto Estate Plan

Step 1: Create a complete inventory of all crypto holdings, including the exchange, wallet type, asset type, approximate quantity, and value. Review and update this inventory at least annually.

Step 2: Prepare an access guide that contains the credentials needed to access every holding: exchange login details (username and master password or stored in a password manager with the master password documented), hardware wallet seed phrases, and any passphrase additions. Store this guide securely.

Step 3: Update your will to specifically reference the crypto holdings, appoint an executor with technical competence, and reference the existence and location of the access guide.

Step 4: Notify a trusted person (spouse, adult child, or lawyer) of the existence and location of the access guide without disclosing the contents. This person can locate the guide after your death and provide it to the executor.

Step 5: For large holdings, consider a multisig wallet structure that distributes access across multiple trusted parties, removing the single point of failure of a single undisclosed seed phrase.

Step 6: For SMSF crypto holders, update the binding death benefit nomination and review the SMSF trust deed with a specialist SMSF adviser to confirm the succession arrangements for the fund.

Step 7: Engage a lawyer familiar with digital assets to review the complete estate plan including the will, access guide structure, and SMSF succession provisions.

Record-Keeping for Beneficiaries

A beneficiary who inherits crypto needs to correctly establish the inherited cost base and acquisition date for future CGT purposes. The inherited cost base is the cost base of the deceased at the date of death (not the market value at the date of inheritance). The holding period includes the deceased period of ownership: if the deceased held Bitcoin for three years, the beneficiary is taken to have held it for three years plus any additional period they hold it.

The beneficiary should obtain documentation of the deceased acquisition date and cost base from the estate records, crypto tax software exports, or exchange transaction history. This documentation is needed to correctly calculate the capital gain when the beneficiary eventually sells. Using crypto tax software that allows manual entry of inherited assets with the correct historical cost base ensures the beneficiary records are accurate from the time of inheritance.

The cost basis methods that applied to the deceased do not necessarily bind the beneficiary for their own tax purposes, but the inherited cost base itself is fixed by the deceased acquisition cost and must be correctly recorded.
