Commonwealth Bank customers in Australia can securely buy Bitcoin and crypto by making transfers to regulated crypto exchanges such as Independent Reserve, one of Australia’s longest-running and most trusted digital currency exchanges. This guide walks you through creating an account, depositing funds, and purchasing Bitcoin, along with CBA’s policies on crypto transactions, and tax considerations.

How to buy Bitcoin with CBA

1. Create your account

To buy Bitcoin and crypto with Commonwealth Bank, start by creating an account on Independent Reserve.

You will need to provide a few documents and details, including:

  • Personal details (full name, email address, date of birth)
  • Proof of address (accepted documents include bank statements, utility bills (gas, water, rates) or government-issued documents (e.g. ATO, vehicle registration, etc.)
  • Proof of identity (driver’s licence, passport, and a selfie)

This ensures compliance with Australian financial laws and enhances security for all users.

2. Deposit funds from Commonwealth Bank

Commonwealth Bank customers can fund their Independent Reserve account using multiple payment options, including:

3. Buy Bitcoin with CBA

Once your funds are available, buying Bitcoin is quick and straightforward.

  1. Log in to your account.
  2. Navigate to the Trade section.
  3. Select Bitcoin from the list of available cryptocurrencies.
  4. Enter the AUD amount you want to purchase.
  5. Select Buy Bitcoin.
  6. Review transaction details and confirm your order.

Once the transaction is complete, your Bitcoin will be credited to your Independent Reserve wallet.

While the steps are the same for desktop and mobile, the desktop and mobile interfaces differ. Below is an example of the mobile app interface.

CommBank’s crypto policies

CommBank may limit the amount you can deposit into cryptocurrency exchanges to no more than $10,000 across your CBA accounts each calendar month.

CommBank will not, however, restrict withdrawals from cryptocurrency exchanges to your CommBank account.

You can read more about this on the CommBank website.

Crypto tax obligations in Australia

According to the Australian Tax Office (ATO), cryptocurrency is considered an asset for capital gains tax (CGT) purposes.

Most of the time (for ordinary investors), the ATO treats buying and selling cryptocurrency like it treats buying and selling shares. This means a CGT event occurs every time you dispose of your cryptocurrency, which includes trading it for another cryptocurrency. If you profit from the sale or trade of a cryptocurrency, then some, or all, of the gain may be taxed.

The rules differ depending on whether you bought the cryptocurrency as an investment or acquired it to use in the same way as fiat money to pay for goods and services. If you’re carrying on a business in cryptocurrency, or you’re a professional trader, there are different rules again, and we suggest you speak to a qualified accountant.
