How to Open a Business Bank Account in Australia

Opening a business bank account in Australia is mostly a 15-minute online application: you need your ABN, photo ID and, for a company, partnership or trust, your registration documents. Sole traders are often approved and transacting the same day. Companies, partnerships and trusts usually take longer while the bank verifies each director or partner and reads the deed or agreement.

Here's what each structure needs, how partnership accounts work, how the big four compare with online accounts, and the second account that saves you at BAS time. For fees, deposit protection and accounting feeds across 16 providers, see business bank accounts compared.

Do you actually need one?

That depends on your structure. business.gov.au puts it plainly: a sole trader doesn't have to have a business bank account, but it's a good idea, while a partnership, company or trust must have a separate bank account for tax purposes.

Sole traders aren't legally required to have a separate business account. If you use one account for both, business.gov.au says you must clearly identify personal payments in your records. In practice, sole traders who skip a separate account usually end up paying a bookkeeper to untangle twelve months of mixed transactions, which costs more than the account would have. Some personal accounts also forbid business use in their terms.

Partnerships need their own account. The partnership has its own ABN and tax file number and lodges its own tax return, so its income and expenses need to be traceable on their own. The section below covers how to set one up.

Companies and trusts are separate again. A Pty Ltd company is a separate legal entity, so the money belongs to the company, not to you. Running company income through your personal account makes the company's financial records (which directors are legally responsible for keeping) much harder to defend, and it's exactly what a liquidator or the ATO points to when arguing the company was never really run as a separate entity. Trust money has to be traceable as trust money for the same reason. If you've registered a company, open the account before the first invoice is paid.

Three reasons that apply regardless of structure:

• Bank feeds. A dedicated account feeds straight into Xero, MYOB or QuickBooks, and every line in the feed is a business line. Mixed accounts mean someone codes hundreds of grocery transactions to "personal" every quarter.
• Audit trail. The ATO requires you to keep records explaining your transactions for five years. A clean account is that record; a shared one means reconstructing it.
• Getting paid. Customers paying "Lee Electrical" rather than "Samantha Lee" looks like a business, and many payers now see a Confirmation of Payee result that checks the account name, BSB and account number against your bank's records before they pay.

What you need to open one

Every provider runs identity verification under Australia's anti-money laundering rules. Get your ID together first, then the structure-specific paperwork.

Two things trip people up. First, an ASIC-registered business name is not a legal entity; it's a label. The account belongs to the person, partners or company behind it, so you can't open an account in a business name alone. Second, directors need a director ID before they're appointed, and banks will ask for it. If you haven't done the setup yet, work through becoming a sole trader, registering a company or sole trader vs company first, because the account must match the structure.

Opening a sole trader business account online

For most sole traders this is the quickest part of starting out. The major banks and several online providers let you apply on their website or app and check your ID electronically, so you can often be transacting the same day if everything verifies. CommBank and Westpac, for example, publish online applications for sole traders.

Accounts with no monthly fee that accept sole traders, as published on 17 October 2026:

Fees from each provider's published fee guide, via our business bank accounts comparison. Airwallex's entry plan costs $29 a month unless you deposit $5,000 a month or hold $10,000, Revolut's business product data says the business must be incorporated, and Up's terms say its accounts aren't for business use.

Three sole-trader points to check before you apply:

• The name customers will see. Your account is in your own legal name, and some banks can show your business name as well. Ask how the name will appear, because that's what Confirmation of Payee checks when a customer pays you.
• Deposit protection counts across all your accounts. A sole trader's business account is in your own name, so it shares the $250,000 Financial Claims Scheme cap with your personal deposits at the same bank.
• Cash. If you're paid in cash, an online-only provider may not accept deposits at all. Keep a bank account with ATM, branch or Bank@Post deposits alongside it.

Partnership bank accounts: name, signatories and partner exit

A partnership must have its own account, and it needs more planning than a sole trader account because two or more people can move the money.

What name goes on the account

A general law partnership isn't a separate legal entity, so the account is held by the partners. Banks open it in the partners' names (for example "A Nguyen & B Smith"), the partnership's registered business name, or both. Whatever the bank prints, keep these consistent:

• the name on your invoices and quotes
• the name on the partnership's ABN record and any ASIC business name registration
• the name customers enter when they pay you, which Confirmation of Payee compares with the bank's records

A partnership trading under all the partners' own names doesn't need a business name; anything else, such as "Nguyen Smith Plumbing", needs one registered with ASIC. Our guides to choosing a business name and registering one with ASIC cover the steps. The partnership also uses its own ABN for any PayID it registers, where the bank offers ABN PayIDs.

Who has to sign up, and who can sign

Expect every partner to complete identity checks, even a partner who won't operate the account; business.gov.au lists ID for all owners or partners among the things a bank may ask for. Then decide the operating authority, which the bank records when you open:

Partners in a general partnership have unlimited liability for the partnership's debts, so a payment one partner makes can become every partner's problem. Write the account rules into your partnership agreement: who can sign, who holds cards and online banking access, and how drawings are recorded. Our guide to partner drawings and profit shares shows how to reconcile each partner's account, and business partner roles helps you allocate the banking tasks.

Opening can take longer than for a sole trader. CommBank lets partnerships of up to four apply online, while Westpac's online application is for sole traders and companies only, so partnerships go to a branch (as published 17 October 2026).

When a partner leaves

business.gov.au says a partnership dissolves when you change who is in it, and the ATO's partnership change rules decide what happens to the tax registrations. That in turn decides what happens to the bank account.

• Reconstituted partnership (same ABN). If at least one partner continues, the agreement has a continuity clause, the business carries on without a break and there's never only one partner, the ATO can treat it as the same partnership. The partnership keeps its TFN and ABN, but a partner must tell the ATO within 28 days of the change. The bank account can usually continue with the signatories updated.
• New partnership (new ABN). If the change winds up the old partnership, the new one needs a new TFN and ABN and both lodge separate tax returns for the year. Open an account for the new partnership and close the old one once its last transactions have cleared.
• Down to one owner. A partnership needs at least two people. If one partner of two leaves and nobody joins, the continuing owner will trade under their own structure and ABN, and needs an account in that name.

Whichever applies, work through the account changes in this order:

1. Agree the exit terms in writing first, ideally in a dissolution agreement covering how assets and debts are divided, the final accounts and who owns the business name.
2. Remove the outgoing partner's access: cancel their cards and online banking, and change the signing authority with the bank. Ask your bank what form and signatures it needs for the change.
3. Settle the money in the account: the outgoing partner's share, debts owed to suppliers and the ATO, and any final GST or PAYG amounts.
4. Update every payment record: the ATO, customers, payment platforms, direct debits and your accounting feed. If the ABN changes, a registered business name has to be transferred to the new holder through ASIC.
5. Keep the old statements, because the ATO requires business records to be kept for five years and the old partnership still lodges a return.

Some states also expect a public notice that a partnership has dissolved, so check with your state business authority. A lawyer or accountant can help with the agreement and the tax steps.

Big four versus online business accounts

The choice is no longer "bank or nothing". Australian and international providers now offer business transaction accounts with a BSB, account number, debit cards and accounting integrations. They can be very good, but they're not identical to a bank, and the difference matters most on the day something goes wrong.

As at 17 October 2026, from our business bank accounts comparison.

The Financial Claims Scheme point is worth pausing on. The $250,000 government guarantee applies per account holder per authorised deposit-taking institution, and a company or trust counts as its own account holder. Brands that share one banking licence, such as St.George and Westpac, share one cap. If a provider isn't an ADI, that protection isn't there. That's not a reason to avoid them, because plenty of businesses run day-to-day on a fintech account and keep reserves at a bank, but make it a conscious choice and check APRA's list.

Whatever you pick, confirm the accounting feed before you start using the account, because retyping bank transactions by hand is the most avoidable cost in small business bookkeeping. See accounting software bank feeds explained and our comparison of accounting software for Australian businesses.

The fees to actually check

Advertised "$0 monthly fee" rarely tells the whole story. Before you apply, look at:

• Monthly account-keeping fee and what it includes. All four major banks offer a no-monthly-fee business transaction account and a $10 tier with some assisted transactions included (as at 17 October 2026). ANZ cut Business Extra's included transactions from 20 to 5 on 30 September 2026, so check the current fee guide.
• Cash handling. On the no-fee tiers, a staff-assisted counter cash deposit costs $3 to $5 at the major banks, while deposits at their own ATMs are free. For a cafe or market stall this can dwarf the account fee.
• International transfers. Compare the amount that arrives overseas, not just the flat fee. Banks don't publish their exchange rate margins.
• Dishonour and overdrawn fees. Cheap to avoid, expensive to discover.
• Merchant fees, if you take cards. Covered below, and usually the largest banking cost a retail business has.

Open a second account: the tax account

Open two accounts on the same day, not one. The second, call it "Tax", exists to hold money that was never yours: GST you've collected, PAYG withheld from staff wages, and a provision for your own income tax. Move the money the day it lands, and BAS day stops being an event.

This fictional example assumes a GST-registered sole trader, $33,000 of fully taxable sales received and $13,200 of fully creditable business expenses paid in the same quarter, with the required evidence and no other adjustments. It uses a chosen 30% income-tax provision, not a calculated tax rate.

That's $7,200 out of the $33,000 that came in, about 22 cents in every dollar banked. An automatic sweep can help build a reserve, but this illustrative percentage cannot guarantee the next tax bill is covered. Reconcile the reserve to actual liabilities and update the estimate when income or expenses change. Your own figure will differ: the income tax percentage depends on your total taxable income and your marginal rate, so ask your accountant for a number that fits you rather than defaulting to 30%. If you're not registered for GST yet, check where the $75,000 threshold sits; you have 21 days to register once you cross it.

A third account, "Profit" or "Buffer", is a worthwhile habit once the tax account is running. Our guide to business savings accounts and term deposits compares where to hold it, and cash flow management covers the full system.

Merchant facilities: taking card payments

Your bank account and your card terminal are separate decisions; you don't have to buy both from the same provider. Standalone providers such as Zeller and SumUp charge a flat 1.4% and Square 1.6% of each in-person card sale with no terminal rental, while the banks quote lower percentages, sometimes with a monthly terminal rental (as at October 2026). Our EFTPOS machines comparison and Zeller vs Square work through the break-even points.

Check these payment costs when comparing accounts:

• Check current surcharge rules. The October no-surcharge changes are now in force, including PayPal from 5 October. Start with the RBA's network-specific guidance and verify your provider's terms. Our payment-channel checklist covers terminals, checkout and invoice links.
• Compare the current merchant-service quote. Ask for your applicable fixed and transaction charges in writing. A lower interchange cap does not, by itself, establish what your business will pay.

Ask whether least-cost routing is available, how it operates under your pricing plan and whether it changes the amount you pay. Confirm settlement timing and any fees before choosing the arrangement.

Keeping the account clean

• Connect the feed on day one so the account reconciles itself instead of building a backlog.
• Get a business debit card and use it for nothing personal. One coffee is a journal entry later; if it happens, record it with our guide to personal purchases through the business account.
• Don't take money out of a company casually. Company money isn't yours until it's paid as a wage (with PAYG withholding and 12% super guarantee), as a dividend, or as a documented loan under the ATO's Division 7A rules. Ask your accountant how to draw before you start, not at tax time.
• Keep statements for five years. The ATO's record retention period covers bank statements and deposit books as much as invoices.
• Review annually. Fee structures and FX margins move. If you switch, open the new account first and run both for a full billing cycle; the switching checklist covers PayID, direct debits and the ATO.

Key takeaways

• Sole traders aren't legally required to have a separate business account, but business.gov.au says partnerships, companies and trusts must have one for tax purposes.
• Have your ABN and photo ID ready; companies also need the ACN, ASIC certificate of registration, constitution, director IDs and a signatory resolution, partnerships need ID for every partner, and trusts need a certified copy of the deed.
• For a partnership, keep the account name consistent with your invoices and ABN, set the signing authority in writing, and plan for a partner leaving: whether the ABN survives decides whether the account can continue.
• Sole traders can usually open a no-monthly-fee account with a major bank, often online and the same day; check whether an online provider is an ADI and whether it takes cash.
• All four major banks offer a $0 monthly fee business account and a $10 tier (as at 17 October 2026), so compare cash deposit fees, FX costs and accounting feeds rather than the headline fee.
• Open a second "tax" account on the same day and sweep GST and your income tax provision into it as money arrives.
• From 1 October 2026 card surcharging is banned on most networks, so review your pricing and ask your provider about least-cost routing.
