How to Stay Compliant and Avoid Exit Tax Surprises When Expatriating in 2026

For many Australians who have spent years living and working in the United States, the decision to give up a US green card or renounce US citizenship can feel like the final chapter of a major life stage. However, before you can fully exit the US tax system, there is one last administrative hurdle: IRS Form 8854, the Initial and Annual Expatriation Statement.

Form 8854 determines whether the IRS will classify you as a covered expatriate, the status that triggers the US exit tax. This process applies to US citizens and long‑term residents (generally green card holders for at least 8 of the last 15 years).

This guide provides a clear explanation tailored specifically to Australian expats navigating expatriation in 2026, with updated figures sourced from Greenback Tax Services.

Why IRS Form 8854 for Australian Expats Matter

IRS Form 8854 serves two critical functions:

1. Certifying your tax compliance

You must confirm you have filed all required US tax returns, including FBARs and foreign information forms, for the five years prior to expatriation.

2. Determining whether you’re a “covered expatriate”

Covered expatriates may face significant taxes on worldwide assets. Failure to file Form 8854 automatically makes you a covered expatriate and can trigger penalties.

Part 1: General Information (Required for All Expatriates)

Every expatriating Australian completes Part 1. This includes:

• Your name, address, and taxpayer identification number
• Your new country of residence (e.g., Australia)
• Details of your immigration status
• Whether the filing is initial or annual

This section is straightforward and will remain the same each year if you must file subsequent annual forms.

The Three Exit Tax Tests (Covered Expatriate Rules)

Part 2 is the core of Form 8854 for the year you expatriate. Here, you determine whether you meet the criteria for covered expatriate status.

You are a covered expatriate if you meet any of the following:

1. Income Tax Liability Test

Your average annual net income tax liability for the previous five years exceeds:

• USD $211,000 (2026 threshold)

This refers to your actual US tax liability after credits, not your income or AGI.

Because many expats use the Foreign Earned Income Exclusion or Foreign Tax Credit, it’s common for Australians abroad to have low or even zero US tax liability.

2. Net Worth Test

• Your worldwide net worth is USD $2 million or more on the date of expatriation (per individual, not household)

This includes property in Australia, investments, superannuation (depending on structure), and US assets.

3. Compliance Test

• You cannot certify full compliance with US tax obligations for the previous five years.

Even if your net worth is minimal, failing this test makes you a covered expatriate.

How the Exit Tax Is Calculated

If you are classified as a covered expatriate, the US imposes a mark-to-market exit tax, treating you as if you sold all your assets (globally) the day before expatriation. This includes:

• Australian property
• US real estate
• Managed funds
• Shares
• Business interests
• Certain trust interests

You then pay tax on the unrealised gain.

2026 Capital Gains Exclusion Amount

The IRS allows you to exclude the first portion of unrealised gains:

• USD $910,000 exclusion for 2026

This exclusion applies before calculating taxable gain on worldwide assets.

Mark-to-Market Rules Explained

Some categories do not fall under deemed sale rules:

• Eligible deferred compensation
• Ineligible deferred compensation
• Certain tax‑deferred accounts
• Interests in non‑grantor trusts

These have special taxation rules and require professional guidance.

What Assets Are Subject to Exit Tax?

In part 2, section  requires you to report your assets. That is;

• Cash
• Shares and marketable securities
• Real property
• Personal property
• Business interests
• Liabilities such as mortgages

For each item, you must report:

• Fair Market Value (FMV)
• Adjusted basis (what you originally paid, plus eligible cost base adjustments)

This determines your potential exit tax exposure.

Part 2, Section C: Only for Covered Expatriates

You complete this section if you:

• Meet covered expatriate criteria
• Hold deferred compensation
• Have tax-deferred accounts
• Are a beneficiary of a non‑grantor trust

This section includes detailed calculations and, in some cases, IRS valuation requirements.

Part 3: Annual Expatriation Statement

You only file Part 3 in subsequent years if:

• You previously elected to defer exit tax,
• You receive payments from eligible deferred compensation, or
• You maintain an interest in a non‑grantor trust.

Once you no longer hold such interests, you stop filing Form 8854.

When Is Form 8854 Due?

You must file Form 8854 with your final US tax return, due on the standard tax filing deadline for that year (generally 15 April). Failure to file may trigger a $10,000 penalty and continued US tax residency status and taxation on worldwide income.

Exit Tax Tips for Australian Expats

1. Work with a specialist

US expatriation tax can be highly complex, especially when global assets such as Australian superannuation, trusts, or property are involved.

2. Ensure five-year compliance

This is the most common downfall. All returns, FBARs, and foreign reporting forms must be filed.

3. Monitor your net worth

Currency fluctuations between AUD and USD can unexpectedly push Australians over the $2 million threshold quite easily.

4. Consider pre-expatriation planning

Gift strategies or restructuring assets may help avoid covered expatriate status.

Final Thoughts on Avoiding Exit Tax Surprises When Expatriating in 2026

Relinquishing a US green card or citizenship is a major milestone and understanding your obligations under the exit tax rules is essential for making a clean break from the US tax system. But beyond navigating the forms and disclosures, the most important takeaway for Australians is this: your success depends heavily on knowing your obligations before you expatriate, or as soon as practical.

The IRS thresholds, such as the five‑year tax compliance requirement, the average tax liability test, and the USD $2 million net‑worth test, are all rules that cannot be fixed retroactively. Many expats discover too late that missed filings, unreported accounts, or oversight of valuation requirements will classify them as covered expatriates, sometimes when some knowledge and thoughtful planning would have kept them out of the IRS’s tax net.

Once you cross these thresholds or fail a compliance test, it can be much more difficult to manage your tax liability through effective planning.

That’s why it is crucial to plan early and proactively. Understanding the rules early on allows you to:

• Ensure your tax filings are complete and accurate
• Monitor your net worth to avoid inadvertently crossing the $2 million threshold
• Consider restructuring your investments to mitigate the impact
• Maintain proper documentation and asset valuations
• Avoid the heavy administrative and financial burden of covered expatriate status

In short, effective expatriation is not something to figure out on the way out the door. By being mindful of your US tax obligations years in advance, Australian expats can protect themselves, minimise unnecessary tax exposure, and transition out of the US system smoothly and confidently.

The most important step is to understand your tax residency and make the correct disclosures from the start. Tax decisions should never stand alone; integrate them into your broader financial and lifestyle planning, especially if you hold significant assets in multiple jurisdictions.
