Foreign currency for Australian businesses: what you need to know

If your business imports goods or services — from the US, Europe, China, or elsewhere — you are routinely dealing with foreign currency invoices. The most common scenario: a supplier invoices you in USD or EUR, you convert at whatever the spot rate is when you pay, and the AUD amount actually debited from your account differs from what you recorded when the bill arrived. That difference is a foreign exchange (FX) gain or loss, and it needs to be treated correctly in your accounts and your tax return.

The ATO's rules on FX gains and losses are set out in Division 775 of the ITAA 1997. For most Australian businesses, FX gains are assessable income and FX losses are deductible — but timing matters. The gain or loss is generally recognised when the obligation is settled (i.e., when you pay the invoice), not when the invoice is received. If you use a forward contract or currency option to hedge the payable, different rules apply. Businesses with significant import volumes should get specialist advice on whether to elect into the ATO's financial arrangement rules (TOFA).

For GST purposes, import transactions have their own treatment. Goods imported into Australia attract GST at the border (collected by the ABF), which is generally claimable as an input tax credit. Services imported from overseas suppliers (such as software subscriptions or consulting) may be subject to the reverse charge rules if the supplier is not GST-registered in Australia. The AUD value of the transaction for GST purposes is converted using the exchange rate at the time of the transaction.

How to use this FX calculator

1. Enter the invoice amount in the foreign currency (e.g., USD 15,000 from a US supplier).
2. Select the currency pair — the calculator uses indicative rates to convert to AUD.
3. Use the result to estimate the AUD cost of the invoice for budgeting, purchase order approval, or accrual purposes.
4. When you actually pay, record the AUD amount debited and compare to the accrued figure — the difference is your FX gain or loss for that transaction.

What exchange rate should I use for accounting purposes?

For recording invoices in your accounting system, use the spot rate on the transaction date. Most accounting software (Xero, MYOB) will look up a rate automatically when you enter the invoice date. The ATO also publishes monthly average exchange rates that smaller businesses can use as a simplification measure. The key requirement is consistency — don't switch between spot rates and averages within the same period without good reason.

What is hedging and should my business use it?

Hedging means locking in an exchange rate today for a payment you will make in the future — typically using a forward contract through your bank or a specialist FX provider. If you have large, predictable USD or EUR payables (for example, quarterly bulk orders from an overseas manufacturer), hedging removes the uncertainty about what those invoices will cost in AUD. The trade-off is that you give up potential gains if AUD strengthens. For businesses where FX swings materially affect margins, hedging is worth discussing with your CFO or bank.

How are FX differences handled in AP automation?

When a foreign currency invoice is processed manually, FX differences are often mishandled — the invoice gets recorded at the wrong rate, the payment goes out at a different rate, and reconciliation takes hours. AP automation platforms that integrate with Xero or MYOB can capture the invoice in the original currency, record it at the correct spot rate, and automatically recognise the FX difference when payment is made. This saves reconciliation time and keeps your FX gain/loss ledger accurate without manual adjustments.
