How to open an online share trading account

What you need before you start

Before opening an account, gather three things: a form of photo ID (driver's licence or passport), your Tax File Number (TFN), and your bank account details for linking. A TFN isn't compulsory to open an account, but skipping it means tax is withheld at the top marginal rate on any unfranked dividend income you receive — most beginners provide it upfront to avoid the surprise later.

Most Australian brokers also ask for your residential address history and employment details as part of standard anti-money-laundering and counter-terrorism financing (AML/CTF) checks — this is a legal obligation for the broker, not something specific to you, so expect the same questions regardless of which platform you choose.

Choosing the right type of account

Individual, joint, company, trust, or self-managed super fund (SMSF) — most beginners open an individual account in their own name, which is the simplest option and the quickest to verify. A joint account works well for shared investing with a partner, but both parties typically need to consent to trades and account changes.

Company, trust and SMSF accounts involve extra documentation — trust deeds, company extracts, and sometimes a certified copy of a fund's trust deed — and are usually set up with guidance from an accountant rather than through a self-service online form. Unless you already have a specific reason to use one of these structures, an individual account is the practical starting point.

HIN vs custodian model — why it matters

A broker-sponsored HIN (Holder Identification Number) means the shares sit directly in your name on the ASX's CHESS register — you get a HIN and can move those holdings to another broker relatively freely, because the ASX's own record shows you, not the broker, as the holder.

A custodian model pools client shares under the broker's own name or HIN, which is often cheaper or fee-free to run, but means you don't hold a HIN yourself — moving providers later can be more involved, since the broker (not the ASX register) is the one who has to action the transfer. Neither model is "wrong," but it's worth knowing which one you're signing up for before you commit, especially if portability between brokers matters to you.

Step-by-step: opening the account

1. Pick a broker and compare fees and account type
2. Start the online application (10–15 minutes)
3. Enter personal and tax details (TFN optional)
4. Choose an individual, joint, company or trust structure
5. Upload ID for verification
6. Link and verify your bank account
7. Wait for approval (often same-day, up to a few business days)

Most of the time in this flow is spent on step two — the application form itself — rather than waiting. Have your ID and bank details ready before you start and the whole process rarely takes more than 20 minutes of active time.

Linking and funding your bank account

Most brokers use a small deposit or verification step — or direct bank-feed matching — to confirm the linked account actually belongs to you before your first trade can settle. This protects both you and the broker from funds being sent to or from an account that isn't yours.

Funding methods vary by platform: BPAY and direct debit are widely supported and typically take one to two business days to clear, while PayID or OSKO transfers can land in your trading account almost instantly, which matters if you want to place a trade the same day you fund the account.

Verifying your identity

Australian brokers are bound by AML/CTF obligations, so ID verification is mandatory, not optional, regardless of which platform you choose. Most brokers now use instant digital verification — matching your ID against government databases — rather than requiring certified paper copies sent by mail.

Expect this step to be near-instant for most applicants, with manual review only kicking in if something doesn't match automatically — a changed address that hasn't been updated on your licence, for example, or a name that doesn't exactly match across documents. If you're asked for manual review, it doesn't necessarily mean anything is wrong; it just means a human needs to check the details a computer couldn't confirm.

Placing your first trade

Once approved and funded, you can place a market order (executes at the current price) or a limit order (executes only at your specified price or better). For a first trade, many beginners use a limit order to avoid unexpected slippage on a volatile stock — you set the maximum price you're willing to pay, and the order simply won't fill above it.

If you're still deciding what to actually buy — an ETF, an individual company, or a mix of both — our guide to the steps for starting to invest in shares walks through that decision in more detail.

Common account-opening mistakes

• Not linking a bank account in your own name, which gets rejected by verification.
• Skipping the TFN and being surprised by withholding tax on dividends later.
• Not checking whether the account uses a HIN or custodian model before committing.
• Comparing headline brokerage only, while ignoring inactivity or account-keeping fees.
