Question About Tax Information for Amazon Australia (ABN/VAT/GST Registration)

Hello everyone,

I am a US-based Amazon seller operating under a C-Corp structure. Recently, I expanded my business to Amazon Australia and began setting up my tax information for the Australian marketplace. I have a question regarding the tax documents and registration numbers required by Amazon Australia.

In the tax document section, I used my US Tax ID (EIN) to set things up, but when I got to the "Tax Information" section under ABN/VAT/GST Registration Numbers and RFC ID, I’m unsure whether I need to apply for an Australian ABN (Australian Business Number), VAT, or GST registration.

Since I’m based in the US, can I continue using my EIN, or do I need to apply for an ABN or other Australian-specific tax identification numbers to comply with local regulations?

I appreciate any insights or experiences from sellers who have gone through this process. Thanks in advance for your help!
