GST on Imports in Australia: A Small Business Guide

You've paid an overseas supplier, the shipment has landed in Australia, and your customs broker is asking for money before the goods can be released. The invoice says one amount, the freight bill says another, and the GST figure on the import documents doesn't match the number in your accounting software. For a tradie or small importer, that confusion can hold up stock, squeeze the bank account, and create a messy BAS.

The headline is simple: GST on imports is generally 10%. The working question is harder: who collects it, what value does the ATO tax, when do you pay it, and can your business recover it as an input tax credit? Australia's import GST system uses a A$1,000 customs-value threshold, so a shipment's value band affects whether GST is usually collected at the border or by an overseas seller at checkout. The Australian Taxation Office explains the GST rate in Australia in broader terms, but importers need to understand the mechanics behind the figure.

When and How GST on Imports Actually Applies

Australia applies 10% GST to the value of a taxable importation. The Australian Border Force guidance on GST and other import taxes states that most imported goods are liable for GST unless a specific exemption applies. Certain categories, including some medical, food, or religious items, may receive special treatment, so don't assume every product follows the same path.

The A$1,000 customs-value threshold determines the usual collection point. Goods with a customs value over A$1,000 are generally taxed at the border through the customs process. Goods at or below A$1,000 generally fall outside border GST collection under the standard import regime, although low-value imported goods rules can require a non-resident seller or marketplace to collect GST before dispatch. Alcohol and tobacco also sit outside the ordinary low-value treatment.

Use three checks before the shipment leaves

1. Identify the shipment type. Is your business importing commercial stock, tools, equipment, samples, or a consumer parcel? The purpose affects your records and the way you assess recoverability.
2. Confirm the customs value. Don't rely on the supplier's product invoice alone. Freight, insurance, duty, and other prescribed amounts can affect the taxable importation value.
3. Find the collection point. High-value goods usually involve border payment. Low-value goods may show GST on the seller's or marketplace's checkout invoice.

The importer of record remains responsible for accurate declarations and the resulting liabilities, even when a freight agent or customs broker pays the amount upfront to obtain release. That broker payment is a settlement method, not a transfer of responsibility.

Practical rule: Treat the customs entry, commercial invoice, freight records, and GST coding as one transaction. Splitting them across unrelated software entries creates avoidable reconciliation problems.

For a plain-English overview of the threshold and collection pathways, Australian GST import thresholds explained is a useful supplementary resource. The important point for your cash flow is that the 10% rate isn't the whole story. You need to know how long the cash remains tied up and whether your business can claim the GST back.

Understanding the Value of the Taxable Importation

The ATO doesn't calculate import GST solely on the overseas supplier's invoice. GST applies to the value of the taxable importation, which includes the customs value of the goods, customs duty, transport costs to the place of consignment in Australia, insurance for that transport, and wine tax where relevant. The ATO guidance on GST and imported goods sets out the broader calculation.

That distinction matters because a purchase can look affordable in the supplier's currency while producing a higher Australian taxable base. Incoterms can determine which party arranges or pays freight and insurance, but they don't automatically remove relevant costs from the taxable calculation. Customs valuation can also involve assists, royalties, or other amounts connected with the goods, so your broker needs complete commercial information.

Worked example

Assume you import tools with a customs value of A$2,000, pay A$200 for international freight and insurance, and incur A$100 in customs duty. The GST base becomes A$2,300, not A$2,000, before any other relevant costs are considered. At 10%, the GST on that stated combination is A$230. If the shipment also includes applicable transport to the place of consignment or another included amount, the final VTI can be higher.

The table below shows the core arithmetic. It deliberately separates duty from GST, because duty increases the GST base rather than replacing GST.

The ATO also provides a practical worked example of taxable importation value, including the principle that GST applies to the aggregated value rather than the sticker price.

Why under-declaring freight creates trouble

Understating freight can distort both the border GST and the input tax credit recorded later. Keep the supplier invoice, freight invoice, insurance document, duty assessment, and import declaration together. If the Australian Border Force reassesses the entry, the importer may face additional amounts and administrative consequences, particularly where the declaration lacks reasonable support.

High-Value Versus Low-Value Goods Explained

The threshold creates two practical lanes for Australian GST on low-value imported goods. A shipment with a customs value over A$1,000 generally follows the border pathway. A shipment at or below A$1,000 can follow the supplier-side pathway, where a non-resident seller or marketplace collects GST at checkout under the low-value imported goods rules.

Australia extended GST to low-value imported goods sold to Australian consumers on 1 July 2018, a reform described in the ATO guidance for Australian consumers importing goods and services. Overseas suppliers, electronic distribution platforms, or redeliverers generally need to register once their Australia-connected sales reach A$75,000 or more in a 12-month period.

The two collection pathways

For a high-value consignment, the importer or broker lodges the customs entry through the Integrated Cargo System, and GST is generally paid before release. For a low-value transaction, the overseas seller or platform may add GST to the customer’s checkout total and remit it to the ATO.

The ATO rules for GST on low-value imported goods confirm that a non-resident business may have to collect GST when it sells goods with a customs value of A$1,000 or less into Australia. A handbag sold for A$700 would attract 10% GST at checkout when the regime applies.

Don’t split an order or label a commercial purchase as a gift to avoid the paperwork. The correct treatment depends on the customs value, the goods, the seller model, and the applicable exclusions. For businesses reviewing broader changes, Australian GST reform information can provide additional context, but your shipment records must drive the actual BAS treatment.

Claiming Input Tax Credits and Reporting on Your BAS

A GST-registered business can generally claim an input tax credit for eligible GST paid on business imports. The credit doesn’t arise automatically because money left your bank account. You need evidence that the business incurred the GST, the import relates to creditable business activity, and the amount belongs in the relevant reporting period.

For a high-value shipment, the customs assessment or import declaration normally provides the critical GST evidence. Your accounting file should also contain the supplier’s commercial invoice, freight and insurance breakdown, customs duty record, and broker statement. The ATO information on importing goods and services as an Australian business supports the need to connect the import transaction with the GST claim.

A clean BAS workflow

Assume a shipment produces a customs-assessed GST amount of A$350. Your accounting software should capture the import purchase and the GST evidence, report the relevant transaction value at G1 where required, and claim the eligible import GST at 1B. The credit reduces the net GST payable in the BAS period that includes the import settlement date.

The supplier invoice date doesn’t control the import GST credit if the border settlement happens later. Reconcile the customs record to the BAS period in which the GST was paid or otherwise becomes claimable. If the shipment clears in a different period from the supplier invoice, don’t force both documents into one period just because they relate to the same order.

Low-value GST collected by a supplier or marketplace can still be a creditable acquisition for a GST-registered business, provided the purchase meets the normal requirements. The marketplace receipt needs to show enough information to support the claim and must not be duplicated with a border GST entry.

For a broader explanation of GST input tax credit entitlement, focus on the evidence and business-use requirements rather than treating every import payment as automatically recoverable.

Practical Examples for Tradies and Small Business Importers

A sparkie orders a tool chest from a German supplier for A$4,200. The shipment sits above the A$1,000 customs-value threshold, so the broker handles the import entry and the business pays A$420 GST at the border, assuming the relevant taxable base is A$4,200 for this simplified illustration.

The sparkie records the border GST separately from the tool purchase. On the next BAS, the business reports the relevant purchase information at G1 and claims the eligible A$420 at 1B, supported by the import declaration and customs assessment. The supplier's commercial invoice is missing the freight breakdown, so the sparkie chases the German supplier before filing rather than relying on an email confirmation with no clear tax or shipping detail.

That distinction matters in the workshop. If the customs value was understated, the broker may have used an incomplete figure. If the sparkie claims the GST without a reliable import record, the credit becomes difficult to defend during an ATO review.

The marketplace example

A small retailer buys A$900 of phone accessories through an online marketplace. The marketplace charges GST at checkout under the low-value imported goods model and provides a transaction record showing the GST amount. The retailer records the purchase as an imported business acquisition and claims the eligible GST at 1B, but doesn't create a second import GST entry when the parcel arrives.

Shop-floor test: Ask one question before claiming. “Who actually charged and remitted this GST?” If the marketplace did, don't also claim a separate border amount unless the records prove a second GST charge.

The retailer should reconcile the marketplace settlement report, customer invoice, payment record, and accounting entry. A missing marketplace tax record can leave the credit unsupported, while a duplicate bank-feed rule can post the same GST twice.

Import-heavy operators also need the logistics side organised. If you're comparing systems, find haulage software for importers alongside your accounting workflow, but don't let a freight platform replace the tax evidence. Your bookkeeping system still needs a clear link between the shipment, customs value, GST charge, and BAS period.

Common Pitfalls and the Real Cost of Getting It Wrong

The 10% GST rate attracts attention because it's easy to remember. In practice, timing and recoverability often matter more than the rate. A business can be entitled to a credit but still experience working-capital pressure when GST must be settled before goods leave the border.

Importers commonly make four mistakes:

• They use the supplier invoice as the tax base. The customs value and taxable importation calculation can include more than the product price.
• They omit freight, insurance, or duty. Those amounts can increase the GST base and produce an incorrect estimate.
• They claim in the wrong BAS period. The import settlement date and supporting customs record matter.
• They duplicate marketplace GST. A checkout charge and a border charge aren't interchangeable records.

Consider a tradie who under-declares import GST by A$200 per shipment across 12 imports a year. That creates A$2,400 in incorrectly settled or unreconciled GST over the year, based on the stated amounts. The business may also face shortfall penalties and general interest charges if the error leads to underpaid tax or an incorrect BAS position.

Cash flow needs its own control

The Department of Home Affairs reported A$5.9 billion in GST collected and A$40.4 billion in deferred GST on imported goods in 2024–25, compared with A$5.6 billion collected and A$40.1 billion deferred in 2023–24, as reported in the ATO GST administration performance information. Those figures show that import GST operates at a scale where timing and financing deserve deliberate management.

Review the Deferred GST Scheme with your tax agent if your business repeatedly pays substantial import GST and remains eligible. The aim isn't to avoid GST. It's to align payment timing with the BAS and keep legitimate credits moving through the system.

Gifts and samples aren't automatically safe merely because they're not sold to a customer. Marketplace invoices also need careful review, and deregistration can complicate transactions that cross reporting periods. Don't change GST settings halfway through an import cycle without checking the effect on existing credits, supplier charges, and customs records.

Compliance Checklist and When to Call an Accountant

Use this checklist before each import cycle, then make it part of your monthly bookkeeping review:

1. Calculate the customs value. Include the purchase value and relevant transport, insurance, duty, and other prescribed amounts.
2. Check the threshold. Determine whether the goods sit above or at or below A$1,000.
3. Lodge the ABF entry. Use the Integrated Cargo System pathway for consignments requiring border clearance.
4. Pay GST at the border. For high-value goods, confirm the amount before customs release.
5. Verify supplier checkout. For low-value goods, check whether the overseas seller or marketplace charged GST.
6. Keep documentation. Retain the commercial invoice, freight records, insurance details, import declaration, duty assessment, GST evidence, and payment record.
7. Map BAS labels. Check the treatment for G1, 1B, 1A, and 7 rather than accepting a generic imported-purchase code.
8. Claim input tax credits. Confirm that the business incurred the GST and claim it in the correct BAS period.
9. Review deferred GST eligibility. Ask whether the scheme fits your business's cash-flow pattern.
10. Consult a specialist. Use a registered tax agent or customs broker when the transaction falls outside your normal process.

Know when the DIY approach has ended

Call a registered tax agent before lodging the BAS if you're importing for the first time, disputing parcel-level charges, dealing with a consignment of A$50,000 or more, or responding to an ABF letter about suspected undervaluation. Repeated mismatches between GST collected and credits claimed also justify professional review.

Keep import declarations and supporting records for five years, and make sure your accounting file can trace each BAS amount back to a shipment. Documentation is the practical proof of input tax credit entitlement. A spreadsheet can work for a small number of imports, but a growing business needs consistent shipment references, supplier records, broker statements, and bank-feed rules.

The cheapest time to correct a GST import process is before the BAS is lodged.
