Paying the ATO from Overseas: Bank Details, Currency and What Goes Wrong (2026)

The ATO’s bank account takes international transfers from anywhere in the world — but on three strict terms. The payment must arrive in Australian dollars. The reference field must carry your payment reference number (PRN) and nothing else. And the payment counts on the day the ATO receives it — which can be up to four business days after you send it — not the day it leaves your account. Get any of the three wrong and the result is the same: a balance on your ATO account accruing general interest charge at 11.51% a year, compounding daily — and since 1 July 2025, none of that interest is tax deductible.

1. How do you pay the ATO from an overseas bank account?

Three routes work from outside Australia: an international transfer from your own bank through SWIFT, an international money remitter, or a card payment online — and the ATO’s own instruction for the first is simply to contact your bank and ask how to send a SWIFT payment in Australian dollars. Everything else on the ATO’s payment menu assumes an Australian footing: BPAY runs on Australian banking, direct debit can only be set up against an Australian cheque or savings account (or a card), and the ATO doesn’t yet have PayID.

The three that travel:

• SWIFT transfer from your own bank. The standard route. Your bank sends Australian dollars to the ATO’s account at the Reserve Bank of Australia — the full details are in the next section. Works from any bank that can send international payments; the traps are fees and timing, covered below.
• An international money remitter. The ATO explicitly allows any remitter, with two conditions: the payment is sent in Australian dollars, and the reference field carries an accurate PRN and nothing else. Two providers — OFX and Xe — have a formal agreement with the ATO that is worth knowing about, because it eliminates the two biggest failure modes. Section 5 has the detail.
• Card online. Visa, Mastercard or Amex through the ATO’s online payment service, with a card payment fee added — the international-card rate is the highest on the fee table (1.99% at the time of writing; confirm when paying). One hard deadline to know: after 30 June 2027, credit cards can no longer be used to pay the ATO at all. Debit cards and the other methods remain.

One more route that looks tempting and isn’t: posting a cheque from overseas. The ATO is moving away from cheques generally, delivery times are yours to absorb, and some liabilities (foreign investment application fees, for instance) can’t be paid by cheque at all. Treat it as retired.

2. What are the ATO’s bank details for international payments — and what goes in the reference field?

International payments go to the ATO’s account at the Reserve Bank of Australia. These are the details the ATO publishes, current as at 28 October 2026:

Field	Detail
Bank	Reserve Bank of Australia, 65 Martin Place, Sydney NSW 2000, Australia
Bank identifier (SWIFT)	RSBKAU2S
BSB	093 003
Account number	316385
Account name	ATO direct credit account
Details of payment (Field 70)	Your PRN — nothing else

Always re-check these against the ATO’s own “Other payment options” page before paying — bank details are exactly the thing you don’t want from a third-party article alone, ours included.

The field that does the real work is the last one. Your PRN — payment reference number — is how the ATO matches money arriving at that account to your tax account. It’s printed on your notice, your BAS, and shown in ATO online services, and it’s specific to both you and the type of tax you’re paying: an income tax PRN and an activity statement PRN are different numbers. Two rules follow:

• Use the right PRN for the right debt. Paying a BAS with your income tax PRN puts the money on the wrong account while the BAS keeps aging.
• Put nothing else in the field. The ATO’s instruction is explicit: any other reference or text — your name, “tax payment”, an invoice-style note — causes processing delays when the payment arrives. A delayed match means your money has arrived but your account still shows the debt. Bank transfer forms love to auto-fill this field; clear it down to the PRN alone.

3. Does the payment have to be in Australian dollars?

Yes. The ATO’s instruction for international transfers is unambiguous: the payment must be sent in Australian dollars. The currency conversion happens on your side of the transaction — your bank or your remitter converts, at their rate and their margin, before the money crosses. The ATO doesn’t receive euros or yuan and convert them for you.

That has two practical consequences. First, the exchange rate is a cost you control by choosing where to convert — bank FX margins and remitter margins differ widely, and on a five-figure tax bill the difference is real money. The ATO doesn’t care which you use; it cares that Australian dollars arrive. Second, the amount you owe is fixed in dollars, so the conversion risk is yours. If you budget a tax bill in your home currency months ahead, a moving rate can leave your set-aside short even though you saved diligently. Price the bill in AUD from the start — it’s an AUD debt.

A remitter quote bundles the conversion fee into the foreign-currency amount it asks you for, so what you see is what the transfer costs; a bank SWIFT payment often shows the FX margin and the handling fees separately, and — as the next section covers — some of those fees come out of the payment itself, mid-route.

4. What goes wrong: bank fees, short payments and the four-day lag?

The two failure modes the ATO’s own page warns about are short payments and late payments — and both happen to people who did, in good faith, pay. Take Lukas, selling into Australia from Berlin with stock in FBA Sydney, standard GST-registered, with A$4,800 of GST to pay on his quarterly BAS.

Short: the mid-route fee trap. The ATO’s page says bank handling and exchange fees are generally deducted from your payment at both the overseas bank and their companion bank in Australia, before being forwarded on. Lukas instructs exactly A$4,800; his bank takes its fee, the Australian correspondent bank takes another, and A$4,772 lands. The BAS isn’t paid — A$28 of it is still owing, quietly accruing interest and, eventually, generating letters. The ATO’s own advice is to allow for these fees when arranging the payment: send comfortably over the exact figure (overpayments come back) or use a route where fees can’t touch the principal.

Late: the four-day lag. An overseas payment can take up to four business days to be received and show on your ATO account — and what counts is the received date, not the sent date. Lukas pays on Thursday for a Monday due date; the payment lands Wednesday; it’s two days late. The ATO’s page says it plainly: if your payment is late, you’re responsible for any interest charges.

And a wrong reference compounds either one. Money that arrives with the wrong PRN — or with extra text in the reference field — sits unmatched while your account keeps showing the debt. The fix (a “missing payment” enquiry with the ATO, transfer receipts in hand) costs weeks.

What late actually costs is the general interest charge (GIC): 11.51% a year for the October–December 2026 quarter, applied daily at 0.0315% and compounding. On Lukas’s A$4,800 that’s about A$1.50 a day — survivable. On a A$48,000 company tax bill, fourteen days late is roughly A$212; a year unpaid turns A$4,800 into about A$5,385. And the sting in the modern tail: GIC incurred on or after 1 July 2025 is no longer tax deductible — the law changed, so the 11.51% is a true after-tax cost now, where before it was softened by the deduction. The rate resets every quarter (it was 11.43% the quarter before), so check the current figure — but plan on it staying expensive.

5. What does paying late cost now — and what’s the safest way to pay on time?

The safest route is the one that removes the two failure modes entirely: the ATO has an agreement with two international money remitters — OFX and Xe — under which the PRN you enter is validated before the payment goes, and the Australian-dollar amount you instruct is sent to the ATO without deduction of cross-border or related fees. Full amount, matched on arrival. You can use any remitter you like — the agreement just means that with these two, the short-payment trap and the unmatched-reference trap are handled by design.

Whatever route you choose, the on-time checklist is short:

1. Start from the PRN — the right one for the debt you’re paying, copied exactly.
2. Count back the lag. Treat the due date minus five business days as your real send date for a SWIFT payment; remitters publish their own delivery times.
3. Send in AUD, and over-provide if fees can touch the payment. A bank SWIFT transfer should carry enough margin that two sets of handling fees still leave the full liability covered — excess comes back.
4. Keep the transfer receipt, with the PRN visible — it’s your evidence if a payment needs tracing.
5. Check your ATO account a few days later and confirm the balance is cleared, not nearly cleared.

If the money genuinely can’t be there on time, a payment plan is possible — but GIC keeps accruing inside a plan; it buys time and good standing with the ATO, not cheaper debt. And where a payment went wrong for reasons genuinely outside your control, GIC remission can be requested — the rules on that didn’t change when deductibility did.

The free path is all of the above, done carefully, yourself — the details are public and this article is most of the map. Where a registered agent earns the fee is that we’re watching the account, not the receipt: we see the due date coming, see whether the payment actually landed and matched, chase the A$28 shortfall before it grows letters, and put the remission case when there is one. Overseas clients pay the ATO every week through us without the money going astray — and if the bill behind the payment is the real question, your first BAS as an overseas seller, PAYG instalments explained and what late GST registration costs are the next reads.

This is general information for FY 2026–27, not advice on your circumstances. Bank details and payment mechanics are as published by the ATO at 28 October 2026 — re-check them on ato.gov.au before paying. The GIC rate is set quarterly (11.51% for October–December 2026) and will change; card payment fees are as published at the time of writing. GIC incurred before 1 July 2025 remains deductible under the old rules.
