Selling on Amazon in Australia comes with a clear rule. Once your turnover crosses a set threshold, GST registration amazon sellers rely on becomes compulsory by law. Many sellers get this timing wrong. They register too late, or they misunderstand what counts toward the threshold. Both mistakes create real problems at tax time.
This guide walks you through exactly when to register, how the process works, and what to watch for as your Amazon store grows.
When Amazon Sellers Must Register for GST
The Australian Tax Office sets a clear turnover threshold. Once your business earns more than $75,000 AUD in a 12-month period, GST registration becomes compulsory. This isn’t just profit. It’s your total sales revenue before expenses.
Many new sellers miss this point. They think the threshold applies to profit after Amazon fees and product costs. It doesn’t. The ATO looks at gross sales. A store selling $80,000 worth of product, even at a thin margin, still needs to register.
This is exactly why GST registration amazon sellers timing catches so many people out. The threshold watches revenue, not what actually lands in your bank account after Amazon takes its cut.
You can also register voluntarily before hitting the threshold. Some sellers do this early to claim GST credits on setup costs, inventory, or advertising spend. This move makes sense if you’re investing heavily before sales ramp up.
How GST Registration Actually Works
Registering for GST involves a few clear steps. You’ll need an Australian Business Number first, if you don’t already have one. Most sellers apply for their ABN and GST registration together through the ATO’s online portal.
Once registered, you receive a GST reporting cycle. Most small businesses report quarterly through a Business Activity Statement. Some high-turnover sellers report monthly instead.
Registration also changes how you price and invoice. You must add GST to relevant domestic sales. Your invoices need to show the GST component clearly. Get this wrong from day one, and untangling it later becomes a genuine headache.
Setting up GST registration amazon sellers correctly from the first invoice saves a lot of reconciliation work down the track.
What Counts Toward Your GST Turnover
Calculating your turnover trips up more sellers than any other part of this process. Your GST turnover includes all gross business income. This covers Amazon sales, other marketplace sales, and any wholesale income you generate.
It does not include GST itself, input tax credits, or sales of business assets like old equipment. Refunds and cancelled orders also get excluded from the calculation.
Many Amazon sellers run multiple stores or sell across several platforms. The ATO looks at your combined turnover across all of these, not just one channel. A seller earning $40,000 on Amazon and $40,000 through their own website has crossed the threshold, even though neither channel alone did.
Getting GST registration amazon sellers need right means looking at your whole business, not just one sales channel in isolation.
Registering Through the ATO Portal Step by Step
The actual registration process is straightforward once you know what’s needed. Here’s the general flow most sellers follow:
- Confirm you have an active Australian Business Number
- Log in to the ATO’s Business Portal or use a registered tax agent
- Select GST registration and confirm your expected turnover
- Choose your reporting cycle, usually quarterly for smaller sellers
- Wait for confirmation, which typically arrives within a few business days
Once confirmed, your GST obligations start from your registration date, or from the date you were required to register if you’re backdating.
GST on Amazon’s Fees and Charges
Amazon charges referral fees, FBA fulfilment fees, storage fees, and advertising costs. Each of these carries its own GST treatment, and getting this right matters for your credits.
Fees charged by Amazon Australia typically include GST, which you can claim back as a credit. Fees charged by Amazon’s overseas entities sometimes work differently, depending on the service and your registration status.
This is one of the more common gst registration amazon sellers face when they first set up their reporting. Getting professional advice on your specific fee structure early avoids under-claiming credits you’re entitled to.
Reviewing your GST setup alongside your broader business structure makes this easier to manage from the start, rather than untangling it later.
Common GST Mistakes Amazon Sellers Make
A few mistakes show up again and again among Amazon sellers managing their own GST:
- Registering late after already crossing the turnover threshold
- Mixing up gross turnover with net profit when checking eligibility
- Missing GST credits on Amazon fees and business software subscriptions
- Failing to separate GST-free items from standard-rated products
- Not reconciling BAS figures against actual Amazon payout reports
Each of these creates extra work down the line. Some also risk ATO penalties if left unresolved for multiple reporting periods.
Backdating and Late Registration
If you’ve crossed the threshold without registering, backdating becomes necessary. The ATO expects you to register within 21 days of realising you’ll exceed $75,000 in turnover.
Late registration doesn’t just mean a compliance headache. You may owe GST on sales made after you should have registered, even if you didn’t charge customers GST at the time. This can eat directly into your margin if it’s not planned for.
Catching this early, rather than after several BAS cycles have passed, keeps the correction manageable. A quick review of your Amazon sales history against the threshold date is worth doing if you’re unsure when you crossed it.
Setting Up Systems That Keep GST Simple
Once registered, staying compliant becomes mostly a matter of good systems. A few habits make ongoing GST reporting far less stressful:
- Connect your Amazon account to cloud accounting software that tracks GST automatically
- Reconcile your payout reports against your accounting records each month
- Keep a running note of any GST-free products you sell alongside standard items
- Review your BAS figures before lodging, rather than after the ATO flags an issue
Sellers using cloud accounting tools tend to spend far less time each quarter preparing their BAS, since the reconciliation work happens continuously rather than in a last-minute rush.
Getting GST Registration Right From the Start
GST registration isn’t complicated once you understand the threshold and reporting cycle. The mistakes that trip up Amazon sellers usually come from timing, not complexity. Registering late, miscalculating turnover, or missing credits on Amazon’s fee structure are the most common issues.
A short review with an accountant familiar with e-commerce and Amazon’s fee structure can confirm you’re registered correctly and claiming everything you’re entitled to. This is especially worth doing if your store is approaching the $75,000 threshold or has already crossed it without formal registration.
If you’re unsure where your business currently sits, business advisory support built around e-commerce sellers can help clarify your position before your next BAS is due. Pairing this with a review of your overall accounting setup makes sure your GST reporting stays accurate as your store scales.
Getting GST registration amazon sellers advice tailored to how Amazon’s fee structure actually works puts you in a stronger position heading into every BAS cycle, rather than reacting to issues after they’ve already cost you money.
