What Happens to Your Crypto When You Die? Estate Planning for Australian Investors

The short answer

If you die without a plan, your crypto can vanish, not legally, but practically. Crypto forms part of your estate and passes under your will like any other asset, but inheriting the legal right to it is useless if no one can access the keys. Unlike a bank account, where an executor can present a death certificate and unlock the funds, self-custodied crypto has no recovery mechanism. No keys, no coins, even for your own family.

A workable crypto estate plan solves two separate problems: legal succession (who inherits) and practical access (can they actually reach the wallet). That means having a valid, up-to-date will, plus a secure, separate access plan that tells your executor what you hold, where it lives, and how to get to it, without exposing your keys while you're alive.

One reassuring point for Australians: death itself generally doesn't trigger capital gains tax. Crypto typically passes to your beneficiaries with the cost base carried over, and CGT only applies when they later sell. The bigger risk isn't tax, it's that billions in crypto have already been lost forever because the only person who could access it died without leaving a way in.

Note: This is general information, not legal or tax advice. Wills, estates, and tax are complex and personal. Have your will professionally drafted by an estate-planning solicitor and confirm tax treatment with a registered tax agent.

Why crypto is uniquely fragile at death

For most assets, death is an administrative process. Your executor obtains a death certificate, applies for a grant of probate, and uses those documents to take control of bank accounts, shares, and property. Institutions are legally obliged to hand over assets to the rightful estate.

Crypto held in self-custody breaks that model completely. There is no institution to compel, no "forgot password" link, no court order that can reconstruct a lost private key. The blockchain doesn't recognise wills, executors, or grief. If your heirs don't know the crypto exists, or can't access the wallet, it simply sits there forever, visible on-chain, permanently unspendable.

This is why an enormous amount of crypto is already considered permanently lost: not stolen, just orphaned, locked behind keys that died with their owners. Your legal entitlement to an asset and your practical ability to access it are two different things, and crypto is the one asset class where that gap can swallow your entire holding.

The two problems you must solve

Problem 1: Legal succession (who inherits)

Crypto is property, and in Australia it forms part of your estate. If you have a valid will, your crypto passes according to its terms. If you die without a will (intestate), it's distributed under your state or territory's intestacy rules, which may not reflect your wishes at all.

So the first step is the same as for any asset: have a properly drafted, current will that accounts for your crypto. You don't need to itemise every coin, but your estate plan should make clear that digital assets exist and are covered, and ideally name who should receive them.

Problem 2: Practical access (can they reach it)

This is the part unique to crypto, and the part most people get wrong. Even with a perfect will, your beneficiaries need to be able to physically access the holdings. That requires knowing:

• What you hold and roughly how much.
• Where it lives, which exchanges, which wallets, and where any hardware wallet device and seed-phrase backups are physically located.
• How to access each, without handing the keys to the wrong person, or leaving them somewhere insecure while you're still alive.

Solving succession without solving access leaves your family with a legal right to something they can never touch.

The privacy-versus-access dilemma

Here's the tension at the heart of crypto estate planning. To protect your crypto while you're alive, your keys must be secret and secure, never written somewhere others can find them. But to pass it on after you die, someone trusted must be able to find and use exactly that information. Push too far toward security and your holdings die with you; push too far toward accessibility and you create a theft risk today.

The art of a good plan is resolving that tension safely: making access possible for the right person at the right time, without creating a vulnerability in the meantime. The sections below are about exactly that balance.

Building a crypto estate plan, step by step

1. Make (or update) a professionally drafted will

Have an estate-planning solicitor prepare your will so it's valid and covers digital assets. Critically: do not write your seed phrase or private keys into the will itself. A will can become a public document once probate is granted, so anything in it could be exposed. The will establishes who inherits; a separate, secure document handles how to access.

2. Create a separate access plan (a "letter of instruction")

This is the heart of the plan, a confidential document, kept separate from the will, that records:

• An inventory of your holdings: exchanges and account details, wallet types, and the location of any hardware wallet and metal seed backups.
• Clear, step-by-step instructions a non-expert could follow to access each holding.
• Any passphrases or additional security layers, handled carefully (see below).

The goal is that a trusted executor could, with this document, actually recover the assets, while it remains inaccessible to anyone who shouldn't have it during your lifetime.

3. Store the access information securely

This is where judgment matters. Options people use, each with trade-offs, include:

• Sealed instructions held by your solicitor, to be opened only by your executor on your death.
• A secure physical location (such as a safe or safety deposit box) whose existence and access your executor knows about.
• Splitting the information so that no single location holds everything, for example, keeping the seed-phrase backup and the instructions on how to use it separate, so neither alone is enough to steal funds.

What to avoid: keys or seed phrases stored digitally in plain text, in email, in cloud storage, or anywhere a single breach exposes everything. The same rules that protect you from hackers protect your estate from theft.

4. Tell the right people the plan exists

A perfect plan no one knows about fails. Your executor (and ideally a backup) should know that crypto exists, that an access plan exists, and how to find it when the time comes, even if they don't have the contents now. Many crypto holdings are lost simply because the family never knew to look.

5. Account for exchanges and hardware wallets specifically

• Exchange-held crypto: most reputable exchanges have a deceased-estate process. Your executor typically presents a death certificate and grant of probate to claim the assets. Document which exchanges you use so this can happen at all.
• Hardware wallets: your executor needs both the device and the PIN or seed phrase. Note the device's location and ensure the recovery information is reachable through your secure access plan.
• Multi-signature wallets: if funds require multiple keys to move, your plan must account for where each key is and who can assemble them, otherwise the security that protected you becomes a permanent lock.

6. Consider professional and technical tools

For larger holdings, it can be worth involving an estate-planning solicitor experienced with digital assets, and exploring purpose-built solutions, from split-key (Shamir) backups to specialist crypto inheritance services. Approach "dead man's switch" style services with caution and due diligence, and never rely solely on a third party you haven't vetted.

What about tax when you die?

This is where Australian investors often worry unnecessarily, and where a genuine planning opportunity sits.

In Australia, death itself is generally not a capital gains tax event. When you die, any capital gain or loss on a CGT asset like crypto passing to your legal personal representative or beneficiary is generally disregarded at that point. The beneficiary is generally taken to acquire the asset at your cost base (for assets acquired after CGT began), and CGT applies only when they later dispose of it.

In practical terms, your family usually doesn't face an immediate tax bill simply because they inherited your crypto. But the embedded gain doesn't disappear, it passes to them, and they'll need your cost-base records to calculate CGT correctly when they eventually sell. This is yet another reason to keep clean transaction records: without them, your beneficiaries may struggle to work out what's owed, or overpay.

Note that crypto held inside a self-managed super fund is treated differently and involves death benefit rules and nominations. And the rules here have nuance and exceptions. Confirm your specific situation with a registered tax agent and your solicitor.

Common mistakes

• No will, or an out-of-date one that predates your crypto.
• Putting seed phrases in the will, risking exposure once it becomes a public document.
• Solving succession but not access, heirs inherit the right but can't reach the keys.
• Storing keys digitally in plain text, creating a theft risk while alive.
• A single point of failure, one backup, one location, one person who knows.
• Never telling anyone the crypto exists, so no one knows to look.
• No cost-base records, leaving beneficiaries unable to calculate CGT on later sale.
• Forgetting exchange accounts in the inventory, so estate processes can't be started.

A simple plan most people can implement

You don't need to be wealthy to protect your crypto. A solid baseline:

1. Get a professionally drafted will that covers digital assets.
2. Write a secure, separate access plan listing what you hold, where, and how to access it.
3. Store it safely (sealed with your solicitor, or in a secure location), ideally splitting sensitive elements so no single point exposes everything.
4. Tell your executor the crypto and the plan exist.
5. Keep your cost-base records current, so beneficiaries can handle tax.
6. Review it whenever your holdings or circumstances change.

That's a few hours of work that can be the difference between your family inheriting your crypto and it being lost forever.

Frequently asked questions

Does my crypto automatically pass to my family when I die? Legally, yes, crypto is property and forms part of your estate, passing under your will (or under intestacy rules if you have no will). But legal entitlement isn't enough. If your family can't access the private keys, they can't reach the crypto, regardless of their right to it. You need both a valid will and a secure way for your executor to access the holdings.

Should I write my seed phrase in my will? No. A will can become a public document once probate is granted, so anything written in it, including a seed phrase, could be exposed. Keep your will for establishing who inherits, and record access details in a separate, secure document (such as sealed instructions held by your solicitor) that only your executor can reach after your death.

What happens to crypto on an exchange when someone dies? Most reputable exchanges have a deceased-estate process. The executor typically provides a death certificate and a grant of probate to claim the assets, similar to a bank account. This only works if your family knows which exchanges you used, so include your exchange accounts in your estate inventory.

Is there capital gains tax when I inherit crypto in Australia? Generally, death itself is not a CGT event, the capital gain is usually disregarded when crypto passes to the legal personal representative or beneficiary, who is taken to acquire it at the deceased's cost base. CGT applies when the beneficiary later sells. This means good cost-base records are essential so beneficiaries can calculate tax correctly. Confirm specifics with a registered tax agent.

How do I make sure my hardware wallet can be accessed after I die? Your executor needs both the physical device and the PIN or seed phrase. Document the device's location and ensure the recovery information is reachable through a secure access plan, without leaving the seed phrase somewhere insecure while you're alive. Splitting the device location from the recovery instructions can balance security and accessibility.

What is the biggest risk to my crypto when I die? Not tax, and not the law, it's permanent loss of access. An enormous amount of crypto is already considered unrecoverable because the only person who could access it died without leaving a way in. The single most valuable thing you can do is make sure a trusted person knows the crypto exists and can access it through a secure, documented plan.

Do I need a lawyer for crypto estate planning? For a properly valid will and a sound estate plan, yes, engage an estate-planning solicitor, ideally one familiar with digital assets. The technical access plan you can largely prepare yourself, but the legal structure (the will, and any trusts or SMSF nominations) should be done professionally to ensure it's valid and does what you intend.
