Do I Need an ABN for a Shopify Store? (2026)
Part of the guide: Do I need to register?
No — not to open one. No Australian law makes an ABN a condition of running a store. But if you’re carrying on an enterprise, yes, and there’s a reason this answer isn’t the same as the one for eBay or Amazon: Shopify isn’t a marketplace, so nothing is collected on your behalf and every dollar you take counts toward your own GST turnover.
That’s the part worth understanding. Two sellers with identical products and identical revenue can land on opposite sides of the registration line depending on whose checkout the money went through.

Checked on 29 September 2026 against ato.gov.au on when to charge GST and taxable sales, and abr.gov.au on what an ABN application needs. Shopify’s own settings and documentation are the platform’s, and are yours to check — nothing here should be read as a description of what your admin does today.)
1. Do I need an ABN for a Shopify store?
Not to open one. Entitlement turns on the ABR’s test: you’re carrying on or starting an enterprise in Australia, you’re making supplies connected with Australia’s indirect tax zone, or you’re a Corporations Act company. If none of those is true, you don’t need an ABN — and you aren’t entitled to one.
The ABR is blunt about the second half: “Not everyone is entitled to an ABN.” It attaches a warning worth reading twice — “You may face prosecution or criminal charges if you apply for an ABN, register for GST and claim GST refunds when you’re not entitled.”
So applying “because the store asked for a number” is not harmless. And it can be revisited: “You may be subject to an ABN entitlement review at any time. If we conduct a review, you’ll be asked to provide evidence that you commenced, or took steps to commence, your business or enterprise from the start date provided in your ABN application.”
Are you carrying on an enterprise?
There is no single test. The ABR lists six features, and the answer is what they look like together:
| The indicator | What it looks like for a store owner |
|---|---|
| Significant commercial activity of reasonable size and scale | A real catalogue and real order volume, not one listing |
| Intention to profit, shown by a plan — “unlike with a hobby” | You buy or make goods in order to sell them at a margin |
| Repeated activity | Continuous trading, restocking, a product line |
| Systematic, organised, business-like, records kept | Supplier relationships, pricing method, bookkeeping |
| Carried on like others in the industry | You run it the way other stores in your category do |
| Relevant knowledge or skill | You know the product, the market and the margins |
A Shopify store leans toward “yes” on most of these more often than a marketplace account does, simply because setting one up is a deliberate commercial act — you chose a domain, a theme and a payment gateway. But it isn’t automatic. Someone selling a handful of their own paintings through a one-page store is still doing a hobby, and the store doesn’t change that.
The 47% myth, quickly
Some store owners worry that “without an ABN they take 47%”. That rule is real but it applies where an Australian business pays more than A$75 (excluding GST) for a supply and no ABN is quoted. A consumer buying from your store isn’t in it, so your Shopify payouts aren’t reduced by it. If you also wholesale to Australian businesses, see our article on no-ABN withholding.
2. Why does Shopify change the answer compared with a marketplace?
Because Shopify isn’t an electronic distribution platform. The ruling excludes a service that only provides the infrastructure, and it uses almost exactly this example: “a service provider who builds a website that includes a shopping cart functionality” (LCR 2018/2, para 27).
That one classification decides everything downstream.
On a marketplace, the platform operator can be deemed the supplier on low value imported goods — items with a customs value of A$1,000 or less sold to Australian consumers and shipped from overseas. The platform collects the GST and remits it, and those sales count toward the platform’s GST turnover, not yours (QC 52554).
On your own store there is no deeming and no collection. You are the supplier for every sale, and every dollar of it is in your GST turnover.
Two sellers, same revenue, different answers
Both sell the same goods. Both ship from overseas to Australian consumers, under A$1,000 a parcel. Both turn over A$90,000 a year.
| Through a marketplace | Through your own Shopify store | |
|---|---|---|
| Who is the supplier? | The platform, on those sales | You, on every sale |
| Who collects the GST? | The platform | You — once registered |
| Counts toward your GST turnover? | No | Yes, all of it |
| Over the A$75,000 line? | Possibly never | Yes |
| Registration needed? | Possibly none | ABN + GST, within 21 days |
Same products, same customers, same money. The difference is structural.
The migration trap
This is where it actually bites people. A seller builds up on a marketplace, correctly concludes they have no Australian registration obligation, then launches their own store — and carries the old answer across. From the first sale on the new store, none of the revenue is being absorbed by a platform’s turnover any more. The threshold can arrive within months.
It’s worth adding that the deeming rules don’t apply at all where the goods are already in Australia or where you are the importer (LCR 2018/2, para 50). If your stock sits in an Australian warehouse, you were always the supplier — marketplace or not.
3. What does an ABN actually get you on Shopify — and what’s the GST trap?
The ABN is free, and what it unlocks is GST registration. But the order of operations is where store owners get caught, because a platform’s tax settings can make it look as though the decision has already been made for you.
What makes a sale taxable
The ATO’s wording is the thing to hold onto:
If you are registered for GST – or required to be – the goods and services you sell in Australia are taxable sales unless they are GST-free or input taxed.
A taxable sale also has to be for payment of some kind, made in the course of operating your business, and connected with Australia. But note what sits at the front of that sentence: registration, or the obligation to register, is what brings your sales into the GST system.
Once they’re in it, you include GST in the price, issue a tax invoice to the buyer, pay what you’ve collected on your activity statement — and you can claim credits for the GST in the purchases you needed to make those sales. That credit side is the real value of the ABN for a store with genuine stock, freight and software costs.
The trap: a tax setting is not a registration
Your store’s admin can calculate 10% and add it to a price. That is arithmetic. It doesn’t register you with the ATO, it doesn’t create an entitlement, and the two systems have nothing to do with each other.
If you collect an amount as GST before you’re registered or required to be, that money was never yours to keep. It has to be dealt with — and the fix is usually more work than registering properly would have been. If you think this has happened, it’s worth getting it looked at rather than quietly adjusting the setting.
Running the other way: if you are required to be registered, your sales are taxable whether or not your store is configured to add GST. Leaving the setting off doesn’t remove the liability; it just means the GST comes out of your margin instead of the customer’s payment.
Voluntary registration
Below A$75,000 you can register anyway. It’s worth it when there’s real GST inside your costs — stock, inbound freight, packaging, apps and subscriptions — and less so when your inputs carry little GST. One catch: “If you choose to register, generally you must stay registered for at least 12 months.” It’s a year-long commitment, not a toggle.

4. How do you actually get an ABN for a Shopify store?
Through the Australian Business Register, for free, and mostly with paperwork you already have. The ABR asks you to settle your business structure first — sole trader, partnership, company, trust — because the application differs by entity type.
Here’s what to have ready:
| What | Notes |
|---|---|
| Your TFN, and associates’ TFNs | Partners, directors, trustees — requirements differ by entity type |
| ACN or ARBN | Companies and registrable organisations, obtained through ASIC first |
| Previously held ABN | If you’ve had one before |
| Entity legal name | As it appears on official documents |
| Authorised contacts | Can be a registered tax or BAS agent if authorised |
| Business contact details | Address, postal address, phone, and an email that is 5–200 characters, has no spaces, and doesn’t start with support@, Sales@ or info@ |
| Main business activity | The main source of income for the enterprise |
| Business locations | All premises the enterprise operates |
| Tax or BAS agent number | If you’re using one |
| The start date | See below — this one matters more than it looks |
The start date is a statement, not a formality
The ABR describes it as the “date your ABN is required”, and defines it precisely: “This should be the date that you expect to start any business activities – for example, buying stock. This date can’t be more than six months in the future when you apply.”
Two things follow. First, there’s a hard forward limit — you can’t register a year ahead of an idea. Second, this is the exact date an entitlement review will ask you to evidence. Put the date you genuinely began commercial activity, which for most store owners is when they first bought stock or committed to a supplier, not the day the store went live and not the day you happened to fill in the form.
Then GST, as a separate step
The ABN is the first of two registrations, not both of them. Once you have it you can register for GST — required once your GST turnover reaches A$75,000, or when you start and expect to reach it in the first year, and then within 21 days.
Watch the projected test. Turnover is measured two ways: current (this month plus the previous eleven) and projected (this month plus the next eleven). The obligation starts the month you expect the next twelve months to reach the threshold — not at the end of a financial year, and not when your accountant next reviews things.
5. What changes if you’re selling into Australia from overseas?
Two things: where your stock sits, and a registration-type choice that a domestic store owner never has to make.
Where the stock sits
Goods already in an Australian warehouse or 3PL when they sell are not imports — they’re ordinary domestic supplies made by you, in Australia. That puts you squarely on the ABR’s second entitlement ground (supplies connected with Australia’s indirect tax zone), so you are entitled to an ABN and generally need one, with standard GST registration behind it.
Goods posted from overseas to Australian consumers are low value imported goods when the customs value is A$1,000 or less. On a marketplace the platform would handle those. On your own store, you handle them.
Simplified or standard — and you can’t have both
Non-residents have a lighter path: simplified GST registration, which issues an ARN rather than an ABN, requires no ABN at all, and is designed for overseas sellers of low value imported goods and digital products. It has two hard limits. It claims no GST credits, and it is not available to a non-resident that imports and warehouses goods in Australia.
Crucially, an entity cannot hold an ABN and an ARN at the same time. So this is a choice, and the credits question usually decides it:
| Your situation | Likely fit |
|---|---|
| Direct-shipping only, no Australian stock, few Australian costs | Simplified (ARN) — no ABN needed |
| Stock in an Australian warehouse | Standard, on an ABN — simplified isn’t available |
| Paying GST at the border on inbound stock | Standard, on an ABN — simplified can’t claim it back |
| Wholesaling to Australian businesses as well | Standard, on an ABN — you’ll need to quote it |
That last row connects back to section 1: an ABN quoted on a B2B invoice is what stops the 47% withholding, and an ARN won’t do that job.
Applying from overseas
The online form is not the constraint — the identity evidence is. Non-resident applications turn on certified identity documents, and a wrong or incomplete document set is the usual reason an application fails. Our article on certified identity documents for non-resident ABN applications sets out what’s accepted.
Where it’s worth getting help
If you’re an Australian store owner clearly in business, this is an afternoon’s work you can do yourself: apply for the free ABN with an honest start date, then register for GST when turnover reaches the threshold.
The parts worth a professional view are the ones with a date or a type attached:
- When did you actually cross the line? The projected turnover test and the ABN start date are both statements about timing that you may be asked to support.
- Which registration type, if you’re overseas? Simplified is cheaper to run and forfeits every credit, and you can’t switch between ABN and ARN casually because you can’t hold both.
- Has GST been charged before registration? That’s fixable, but it’s a clean-up rather than a setting change.
- Running a store and a marketplace? Each channel has to be mapped separately, and the turnover treatment differs between them — which is the whole point of section 2.
That’s the difference between doing it and doing it right the first time: the seller who moves from a marketplace to their own store, keeps the old answer, and discovers twelve months later that registration was due in month four.
If you’d like that looked at properly, our initial assessment form scopes it in about twelve questions — what you sell, what you turn over, and where your stock sits — without needing a meeting.
