GST and ABN Requirements for Amazon Australia Sellers: What Cross-Border Sellers Get Wrong

Introduction
Cross-border sellers get more wrong about GST and ABN requirements for Amazon Australia sellers than almost any other part of expanding into the Australian market. It's not because the rules are secret — it's because they sit at the overlap of three different systems (Australian GST law, Amazon's own marketplace tax collection, and customs rules for low-value goods), and most sellers only ever get a partial explanation of one of them.
The result is a handful of the same misconceptions showing up again and again in seller forums, Seller Central support threads, and accountant inboxes: "Amazon handles GST for me, right?" "I have an ABN, so I must already be GST-registered." "FBA means I automatically need to register." None of these are quite true — and believing them can either cost you unnecessary compliance work, or leave you exposed when you didn't realise you needed to register.
This guide is built specifically around those mistakes. Instead of just listing the rules, it shows you where cross-border sellers on Amazon Australia typically go wrong, and what the correct position actually is in each case. If you haven't set up your seller account yet, it's also worth reading our complete guide to selling on Amazon Australia alongside this one.
Quick answer: Selling on Amazon Australia does not automatically require an ABN or GST registration. Amazon may collect and remit GST on eligible low-value imported goods (customs value A$1,000 or less) shipped from overseas. Your own GST and ABN obligations depend on your Australian-connected GST turnover, whether you store inventory in Australia (e.g., via FBA), and how your sales are classified under Australian tax law.
The Core Misconception Behind Most Seller Mistakes
Almost every mistake in this guide traces back to one wrong assumption: that selling on Amazon Australia from overseas is, by itself, an event that triggers GST or ABN requirements. It isn't.
Australian tax obligations are triggered by specific facts — your GST turnover connected with Australia, where your inventory sits, and how a given transaction is classified — not by the simple act of listing products on an Australian marketplace. Amazon's own marketplace GST collection rules exist precisely because many overseas sellers wouldn't otherwise have any Australian tax footprint at all.
Once you internalise that distinction, the rest of this guide is really just working through the specific situations where that general rule shifts.
Mistake 1: Assuming Amazon Handles All Your GST
The mistake: Believing that because Amazon sometimes collects GST, it always does — and that sellers therefore never need to think about GST themselves.
The reality: Amazon generally only collects and remits GST on eligible low-value imported goods (customs value A$1,000 or less) shipped directly from overseas to an Australian customer. This is a genuinely useful rule for small cross-border sellers, but it has real limits:
It typically stops applying once goods are stored in an Australian warehouse, including an Amazon FBA Australia fulfilment centre.
It doesn't cover goods valued over A$1,000, which are usually handled through standard customs/import GST processes instead.
It doesn't remove your obligation to assess your own GST position as your business grows or your fulfilment model changes.
Cross-border sellers who treat "Amazon collects GST" as a permanent, universal fact often get caught out the moment they start using FBA or their turnover crosses a threshold. For a broader look at how GST compliance is shaping up for Australian sellers, see our Amazon Australia GST compliance guide.
Mistake 2: Confusing an ABN with GST Registration
The mistake: Assuming an ABN and GST registration are the same thing — either "I have an ABN, so I must be GST-registered" or "I'm GST-registered, so I must have (or need) an ABN."
The reality: These are two separate registrations:
An ABN is a business identifier tied to whether you're considered to be carrying on an enterprise in Australia (among other entitlement criteria).
GST registration is about whether you need to charge, collect, and remit GST — and it comes in more than one form.
An overseas seller can have an ABN without being GST-registered, and — under simplified GST registration for non-residents — can have specific, limited GST obligations without an ABN at all. Standard GST registration does require an ABN, but that's a one-directional link, not an equivalence.
Cross-border sellers routinely assume that solving one of these automatically solves the other. It doesn't.
Mistake 3: Miscalculating the $75,000 GST Threshold
The mistake: Adding up all Amazon Australia revenue and comparing it to the A$75,000 GST registration threshold, as if every dollar counts the same way.
The reality: For overseas sellers, the threshold calculation is more layered:
Not all sales are legally "connected with Australia" for GST purposes in the same way.
Sales already covered by Amazon's marketplace GST collection don't necessarily count toward your registration threshold the same way sales you're personally responsible for do.
What actually matters is your relevant Australian-connected GST turnover — not simply your total Amazon Australia sales figure.
Sellers who track only their gross Amazon Australia revenue often either register too early (creating unnecessary compliance overhead) or miss the point at which they were actually required to register (creating compliance risk). The fix is tracking Amazon-collected and seller-responsible sales separately, from day one.
Mistake 4: Not Reassessing Tax Position Before Switching to FBA Australia
The mistake: Moving inventory into an Australian Amazon fulfilment centre to speed up delivery, without first checking how that changes GST treatment.
The reality: Once stock is stored in Australia, the transaction generally shifts from being treated as an import of low-value goods to a local supply — and the low-value imported goods marketplace collection rule generally no longer applies in the same way. That means:
Your own GST registration and reporting responsibilities move to the centre of the picture.
If your Australian-connected turnover is at or near the A$75,000 threshold, switching to FBA can be the very thing that pushes you into registration territory.
An ABN (and standard GST registration) may become necessary at this point, where it wasn't before.
Cross-border sellers frequently make the FBA switch first and ask the tax question later — which is backwards. The assessment should happen before stock moves, not after. If you're weighing up the switch, our breakdown of Amazon FBA Australia costs and guide to Amazon FBA fulfilment centres in Australia are good starting points before you talk to a tax adviser.
Mistake 5: Ignoring the Low-Value Imported Goods Rules
The mistake: Treating all products the same regardless of price, without checking whether they fall under or over the A$1,000 customs value threshold.
The reality: Australia's low-value imported goods (LVIG) regime is specifically about goods with a customs value of A$1,000 or less. For qualifying sales, the marketplace operator (Amazon) can be treated as the GST-liable supplier instead of the seller. Goods above A$1,000 are generally routed through standard customs/import processes instead, where GST — and potentially duty — is handled at the border.
Sellers with mixed product catalogues (some items under the threshold, some over) sometimes assume their entire catalogue is covered by Amazon's marketplace collection. It isn't — higher-value items can carry entirely different GST and customs treatment.
Mistake 6: Picking the Wrong GST Registration Type
The mistake: Defaulting to full standard GST registration (with an ABN) when simplified registration would have been sufficient — or the reverse, choosing simplified registration when the business actually needs an ABN and GST credits.
The reality: Non-resident sellers with narrow, specific Australian GST obligations may qualify for simplified GST registration, which doesn't require an ABN but also doesn't allow GST credit claims. Sellers who need to claim GST credits, or who are storing inventory locally via FBA, usually need standard registration with an ABN instead.
Getting this choice wrong isn't usually catastrophic, but it can mean unnecessary paperwork on one end, or missed GST credits on the other.
Mistake 7: Poor Record-Keeping Between Amazon-Collected and Seller-Responsible Sales
The mistake: Lumping all Amazon Australia sales together in bookkeeping, without separating out which transactions Amazon collected GST on and which the seller is personally responsible for.
The reality: Without this separation, it's very difficult to:
Accurately calculate your Australian-connected GST turnover against the A$75,000 threshold
Complete a Business Activity Statement (BAS) correctly if you are registered
Demonstrate compliance if the ATO ever asks questions about your Australian sales
This mistake is less about misunderstanding the rules and more about not building the reporting habits needed to apply them correctly over time. Our broader guide to compliance and legal considerations for Amazon sellers covers record-keeping practices beyond just GST.
What Cross-Border Sellers Should Actually Do
Rather than reacting to each of these mistakes individually, the more reliable approach is:
Separate your sales data — Amazon-collected vs. seller-responsible — from the start.
Track your Australian-connected GST turnover on an ongoing basis, not just once a year.
Reassess your tax position before any structural change — switching to FBA, adding new product price points, or scaling turnover.
Understand the A$1,000 customs value line for every product category you sell.
Choose standard or simplified GST registration deliberately, based on your actual need for an ABN and GST credits — not by default.
Get a second opinion from a registered Australian tax adviser before making registration decisions, particularly around thresholds and FBA transitions.
If you'd rather have this handled alongside the rest of your account setup, our Amazon Seller Central consulting service and Amazon account setup service can help cross-border sellers get these foundations right from day one.
GST and ABN Requirements at a Glance
Selling setup | Amazon collects GST? | Seller's GST position | ABN |
Overseas stock shipped directly to Australian customer (≤A$1,000) | May apply under low-value imported goods rules | Depends on the seller's Australian GST obligations | Not automatically required |
Stock stored in an Australian warehouse (FBA Australia) | Generally not covered by the low-value imported goods marketplace rule | Seller needs to assess its own GST obligations | Required for standard GST registration |
Seller reaches the applicable GST registration threshold | Seller's own GST obligations need to be assessed | GST registration may be required | Required for standard GST registration |
Non-resident using simplified GST registration | Depends on the applicable transaction rules | Simplified GST registration may be available in eligible circumstances | Not required for simplified registration |
Goods valued over A$1,000 | Handled via customs/import GST, not marketplace collection | Import GST generally applies at the border | Depends on broader business circumstances |
The exact GST treatment depends on your business structure, fulfilment model, customer type, and how goods enter Australia. Confirm your specific circumstances with the ATO or a registered Australian tax adviser.
Real-World Scenarios
Scenario A — Small overseas seller, no local stock. A UK seller ships items under A$1,000 directly to Australian customers with no local warehouse. Amazon likely collects and remits GST on qualifying orders. The seller may not need an ABN or standard GST registration unless their Australian-connected turnover grows or their model changes.
Scenario B — Growing seller approaching the threshold. A US seller's Australian-connected turnover is climbing toward A$75,000, still shipping overseas. The mistake to avoid: counting all Amazon Australia revenue equally instead of separating Amazon-collected sales from their own.
Scenario C — Seller switching to Amazon FBA Australia. An Indian seller moves inventory into an Australian fulfilment centre. The mistake to avoid: making the switch first and only checking GST implications afterward, rather than reassessing GST and ABN needs beforehand.
Scenario D — Non-resident with narrow, specific obligations. A Chinese seller's only Australian GST touchpoint is a narrow category of low-value supplies. The mistake to avoid: defaulting to full standard registration and an ABN when simplified registration may be the more appropriate, lighter-touch fit.

Frequently Asked Questions
1. Do cross-border sellers automatically need an ABN to sell on Amazon Australia?
No. An ABN is only required if you're carrying on an enterprise in Australia or need one for standard GST registration — not simply because you sell into the Australian market.
2. Is it true that Amazon always collects GST for overseas sellers?
No. Amazon generally only collects GST on eligible low-value imported goods shipped directly from overseas. Locally stored FBA stock and higher-value goods are typically treated differently.
3. What's the biggest GST mistake overseas Amazon sellers make?
Treating all Amazon Australia revenue as counting equally toward the A$75,000 threshold, instead of separating Amazon-collected sales from sales the seller is personally responsible for.
4. Does switching to Amazon FBA Australia change my GST obligations?
It can. Once stock is stored in Australia, the low-value imported goods marketplace rule generally no longer applies, and your own GST position becomes more central.
5. Can I have an ABN without being GST-registered?
Yes. An ABN and GST registration are separate; having one does not automatically mean you have (or need) the other.
6. Is simplified GST registration a mistake to avoid, or a legitimate option?
It's a legitimate option for non-resident sellers with narrow, specific GST obligations — the mistake is choosing it (or standard registration) without actually assessing which one fits your situation.
7. When should a cross-border Amazon Australia seller register for GST?
Generally within 21 days of realising your relevant Australian-connected GST turnover will exceed A$75,000 — which requires knowing which sales count toward that figure in the first place.
