If you’re an Australian freelancer, Amazon seller, investor, or business owner earning income from U.S. sources, you may need an ITIN Number issued by the IRS.

The US-Australia Tax Treaty allows Australians to reduce or eliminate U.S. withholding taxes on certain income types including royalties, dividends, and freelance or digital earnings. But to claim these benefits or get paid on platforms like Stripe, Amazon, Payoneer, AdSense, or Upwork, you’ll first need a valid ITIN.

At House of Bookkeepers, an IRS-Certified Acceptance Agent (CAA), we help applicants in Australia obtain their ITIN letters securely without mailing passports to the United States.

What Is an ITIN?

An ITIN is a nine-digit tax processing number (format: 9XX-XX-XXXX) issued by the Internal Revenue Service (IRS) to individuals who:

  • Need to file or report U.S. taxes, but

  • Are not eligible for a U.S. Social Security Number (SSN)

An ITIN is not:

  • A visa or work permit

  • Immigration status

  • A substitute for SSN

It simply identifies you for U.S. tax and payment purposes.

Why Australians Need an ITIN

Thousands of Australians receive income from U.S. companies, platforms, or investments often facing a 30% withholding tax unless they apply the US-Australia tax treaty.

With an ITIN, you can:

  • Claim tax treaty benefits and reduce withholding (using Form W-8BEN)

  • Avoid the default 30% U.S. tax on royalties, digital, or freelance income

  • File a U.S. tax return (Form 1040-NR) when required

  • Open or verify U.S. bank and payment accounts (Stripe, Payoneer, etc.)

  • Receive payouts faster from U.S. clients or marketplaces

  • Stay compliant with IRS and platform reporting requirements

Who in Australia Commonly Needs an ITIN?

  • Freelancers, Creators & Digital Workers

Australian professionals earning through Upwork, Fiverr, Amazon KDP, YouTube, AdSense, or Payoneer must submit Form W-8BEN with an ITIN to avoid the 30% default withholding.
Without it, the platform treats your payments as unverified U.S. income.

Benefits:

    • Avoid excessive withholding

    • Get paid faster

    • Stay tax compliant

  • Amazon & E-Commerce Sellers

Australian sellers on Amazon, Etsy, or Shopify who target the U.S. market need an ITIN to:

    • Validate their W-8BEN tax form

    • Receive payouts without unnecessary deductions

    • Maintain verified seller status

  • Property Investors

Selling or renting U.S. property triggers FIRPTA (Foreign Investment in Real Property Tax Act) withholding, typically 15% of the sale price.
With an ITIN, you can file Form 1040-NR and reclaim overpaid FIRPTA taxes.

  • LLC Owners & Entrepreneurs

Australians who form a U.S. LLC need an ITIN for IRS filings and tax compliance.
You may need to provide:

    • Articles of Organization

    • Operating Agreement (if multi-member)

    • IRS EIN Confirmation Letter (CP575 Notice)

If your LLC is single-member, an Operating Agreement may not be required.

  • Filing Jointly with a U.S. Spouse

If you’re married to a U.S. citizen or green card holder, you’ll need an ITIN to file a joint tax return and qualify for family-related credits.

Benefits of Having an ITIN

✔ File U.S. tax returns legally
✔ Claim refunds for overpaid or withheld taxes
✔ Apply reduced rates under the US-Australia Tax Treaty
✔ Avoid 30% default withholding on U.S. income
✔ Comply with FIRPTA when selling U.S. property
✔ Build financial credibility for your LLC or global business

US-Australia Tax Treaty Benefits

The US-Australia tax treaty allows residents of Australia to save significantly on U.S. withholding taxes:

Income Type Default Rate Treaty Rate (Australia)
Dividends 30% 5-15% (depending on ownership)
Interest 30% 10% (or exempt in some cases)
Royalties 30% 5-10%
Scholarships & Fellowships 30% Exempt (subject to treaty terms)

To claim these benefits, you’ll need:
1️⃣ A valid ITIN
2️⃣ The correct IRS form (W-8BEN for individuals, 8233 for researchers/students)

🧾 How to Apply for an ITIN from Australia in 2025

Step 1: Confirm Eligibility

You must have a valid U.S. tax purpose such as:

  • Filing a U.S. tax return (Form 1040-NR)

  • Claiming treaty benefits via W-8BEN

  • Selling or renting U.S. property

  • Filing jointly with a U.S. spouse

  • Managing or owning a U.S. LLC

💡 Note:
If you only need to file W-8BEN for withholding relief, you may qualify under a treaty exception and might not need to attach a full U.S. tax return.

Quick FAQs: ITIN from Australia

Q1. Can I apply for an ITIN from Australia?
Yes. You can apply directly through House of Bookkeepers (IRS CAA) without traveling or mailing your passport to the U.S.

Q2. Does Australia have a tax treaty with the U.S.?
Yes. The treaty reduces or eliminates U.S. withholding on dividends, royalties, and freelance income. You’ll need an ITIN and W-8BEN to claim those benefits.

Q3. Do I need a U.S. address?
No. The IRS can send your ITIN letter to your Australian address. However, a U.S. forwarding address can help receive mail faster. Alternatively, we can receive your letter and email you a scanned copy (not recommended).

Q4. How will you verify my identity?
You’ll provide a selfie holding your passport’s information page — this step confirms your identity and supports your COA verification.

The IRS sends Letter CP565 once your ITIN is issued. If it doesn’t arrive within 13 weeks, contact us — we’ll check with the IRS and update you.
