If you’re a small business owner in Australia, it’s likely you spend money each month on digital tools like Google Ads, Facebook Ads, Canva, Grammarly, Slack, Dropbox, or other cloud subscriptions. Most of these services are billed from overseas, and there’s an important detail you might overlook as a small business owner.
GST Obligations Despite No Charge on Invoices
The ATO has a specific rule that might apply to you: the GST reverse charge. While this rule isn’t new, it is often overlooked by small businesses, including those that use bookkeepers.
This article clearly explains the reverse charge rule, using real examples and a practical checklist.
Why Don’t Google Ads or Canva Charge GST?
Many global digital companies operate outside of Australia or use an overseas billing entity. Even if they have a presence in Australia, their invoicing may still be routed through:
- The US (e.g., many SaaS subscriptions)
- Singapore (Google Ads)
- Ireland (Meta/Facebook)
- Other international hubs
GST is only charged on invoices when the supplier:
- Is making a taxable supply in Australia, and
- Is registered (or required to be registered) for GST.
If the supplier isn’t conducting an enterprise in Australia, the GST rules shift the responsibility to you, the customer. This is referred to as the reverse charge.
Understanding the GST Reverse Charge
Typically, the seller charges GST. However, when you purchase digital services from overseas without GST being charged, the ATO may require you to calculate GST and report it in your BAS. You’re liable for the GST on the purchase price.
The good news? If you’re GST-registered and the purchase is related to your business, you usually can claim an input tax credit, meaning there’s no net cost unless you make input-taxed sales (e.g., financial services, residential rent).
This is why many businesses report reverse charges but end up with a net effect of $0.
Examples from Small Business Clients
1. Google Ads Billed from Singapore
Invoice has no GST → Reverse charge applies.
In BAS:
- You add 10% GST on the amount.
- You claim the same amount as a credit (if eligible).
2. Canva Billed from the US
Invoice has no GST → Reverse charge applies.
3. OpenAI or ChatGPT Team Billed from the US
No GST → Reverse charge applies.
4. Meta/Facebook Ads Billed from Ireland
Often no GST → Reverse charge applies.
5. Xero or Adobe
Some charge GST, while others don’t, depending on the entity and plan. If GST is already charged, then the reverse charge does not apply. Thus, there are inconsistencies, and an accountant can help clarify these differences.
Why the ATO is Concerned
Since 2017, the ATO has been monitoring:
- Foreign digital service providers
- Australian business payments to overseas suppliers
- Mismatches in BAS reporting
- Unclaimed reverse-charge obligations
Audits have identified businesses that:
- Claimed deductions for foreign ads
- Neglected to include the reverse-charge GST
Given that these transactions are now clear (through banks, merchant accounts, and data matching), small businesses should be proactive in their compliance.
