If you’re an Australian with US income or employment connections, you may have heard about Form 1095-C—especially as tax season approaches in 2025. While this form is a US requirement, it can affect Australians working for US companies or those with dual tax obligations. Here’s what you need to know about Form 1095-C, its 2025 updates, and how it might impact your tax situation.
What Is Form 1095-C and Who Receives It?
Form 1095-C is an IRS document provided by applicable large employers (ALEs) in the United States. It details employer-provided health insurance coverage, reporting whether you and your dependents were offered coverage and for which months. For Australians working in the US, on secondment, or employed by a US-based multinational, receiving this form is common.
-
Who gets it? US employees of companies with 50 or more full-time staff, including some Australian expats or remote workers paid from the US.
-
What does it show? Coverage details, employee share of monthly premiums, and employer identification.
For most Australians, this form is informational unless you’re required to file a US tax return. However, if you have dual tax residency or are navigating the US-Australia tax treaty, it’s wise to keep these forms on file.
Key Updates for 2025: Why It Matters Now
2025 brings some updates to the Form 1095-C process, mainly reflecting the evolving US health care landscape post-COVID and the continued impact of the Affordable Care Act (ACA). Here are the most relevant points:
-
Filing Deadlines Extended: The IRS has maintained the extended deadline to furnish 1095-C forms to employees—March 4, 2025, for the 2024 tax year.
-
Electronic Filing Threshold Lowered: Starting this year, employers with 10 or more returns must file electronically, increasing the likelihood that you’ll receive digital copies.
-
ACA Compliance Remains: Although the individual mandate penalty is $0 federally, some US states (like California and New Jersey) still require proof of coverage. If you’ve lived or worked in these states, your 1095-C is essential.
For Australians who spent any time working in the US in 2024, pay close attention to your US tax reporting. Even if you’re back home, reporting requirements may linger, and the 1095-C provides evidence of employer-sponsored health insurance.
How Form 1095-C Impacts Australians: Real-World Scenarios
Let’s look at how Form 1095-C actually comes into play for Australians:
-
Australian Expats Returning from the US: If you returned in 2024 and file a US tax return for part of the year, you’ll need your 1095-C to answer health coverage questions on your US return (Form 1040).
-
Remote Workers for US Companies: Even if you’re living in Sydney but employed by a US firm, you might receive a 1095-C. Keep it for your records, even if it doesn’t affect your Australian tax.
-
Dual Citizens or Green Card Holders: If you’re still considered a US tax resident, you must report global income and complete all health coverage disclosures. Your 1095-C is crucial for compliance.
It’s important to note that Form 1095-C is not submitted with your Australian tax return. But for those navigating both US and Australian systems, accurate record-keeping is essential to avoid double taxation and ensure proper treaty benefits.
Practical Tips for Managing Your 1095-C in 2025
-
Check for Electronic Delivery: Many employers now issue 1095-Cs via secure employee portals or email. Watch your inbox or HR system notifications.
-
Keep Copies: Store digital and paper copies with your tax records for at least three years, in case of audit or future queries.
-
Coordinate with Your Accountant: If you’re using a cross-border tax specialist, share your 1095-C early to avoid filing delays.
-
Review for Accuracy: Mistakes on your 1095-C (wrong coverage months, incorrect employer info) can cause IRS headaches. Contact your employer’s payroll or HR department for corrections.
Conclusion
Form 1095-C may seem like just another piece of tax paperwork, but for Australians with US ties, it plays a key role in cross-border compliance. With 2025’s updated deadlines and digital delivery, it’s more important than ever to stay organised and informed. Whether you’re an expat, a dual citizen, or just spent a few months working stateside, understanding your 1095-C helps ensure smooth tax filings on both sides of the Pacific.
Understanding the US-Australia Tax Treaty
Navigating the complexities of international tax obligations can be daunting, especially when dealing with both US and Australian tax systems. The US-Australia Tax Treaty is designed to prevent double taxation and ensure fair tax treatment. Here’s how it applies to Australians with US income:
Key Provisions of the Treaty
- Dual Residency Solutions: The treaty provides guidelines for determining your tax residency, which is crucial for understanding your obligations in both countries.
- Tax Credits and Exemptions: Australians may claim foreign tax credits in Australia for taxes paid in the US, reducing the risk of being taxed twice on the same income.
- Specific Income Types: The treaty outlines how different types of income, such as dividends, interest, and royalties, are taxed, often reducing withholding tax rates.
Practical Example: Claiming Tax Credits
Consider Sarah, an Australian who worked in the US for part of 2024. She paid US taxes on her salary and now needs to file her Australian tax return. By using the tax treaty, Sarah can claim a foreign tax credit in Australia for the US taxes paid, ensuring she doesn’t pay more than necessary.
Navigating Dual Tax Obligations: A Step-by-Step Guide
Step 1: Determine Your Residency Status
- Australian Tax Residency: Use the Australian Taxation Office (ATO) guidelines to assess if you’re an Australian resident for tax purposes.
- US Tax Residency: Understand the IRS criteria, such as the substantial presence test, to determine if you’re considered a US tax resident.
Step 2: Gather Necessary Documentation
- Form 1095-C: As discussed, this form provides proof of US employer-sponsored health insurance.
- W-2 or 1042-S Forms: These forms report your US income and taxes withheld, crucial for both US and Australian tax filings.
Step 3: File Your Tax Returns
- US Tax Return: Complete your US tax return using Form 1040, ensuring you include all necessary forms and disclosures.
- Australian Tax Return: Report your global income to the ATO, claiming any applicable foreign tax credits.
Step 4: Consult a Tax Professional
Given the complexities of dual tax obligations, consulting with a tax advisor experienced in cross-border taxation can be invaluable. They can help ensure compliance and optimize your tax situation.
