The 7 Best US Tax Accountants in Australia (2026)

Updated October 2026 · 7 picks

The best US tax specialists for Americans in Australia in 2026 include Expat US Tax (Melbourne and North Sydney) for full-service US and cross-border returns, AmTax in Melbourne for streamlined catch-up filings and renunciation, Extax in Sydney for straightforward annual US returns, and PwC Australia for high-net-worth and complex structures.

How we chose

This is a shortlist of established firms that prepare US tax returns for Americans living in Australia — not a ranking. We started with specialists that have an office in Australia and know both systems, then added a Big Four practice for complex cases and a few large US-based online firms that serve Americans in Australia remotely. Each has its own website and a clear US expat focus, and we described each from what it says it does. Nobody paid to be included and there are no affiliate links.

Nothing here is tax advice. Check credentials before you hire anyone: US returns should be prepared by an IRS Enrolled Agent (EA), a US CPA or an attorney — the IRS publishes a Directory of Federal Tax Return Preparers with Credentials, and each US state board of accountancy lists its CPAs. Anyone charging a fee for your Australian return must be on the Tax Practitioners Board register.

US citizens and green card holders must file a US tax return every year wherever they live, on top of their Australian return. Because Australian tax rates are generally higher, most Americans here end up owing little or no US tax — but only if the returns, the FBAR and forms for things like superannuation and Australian managed funds are filed correctly. That is specialist work, and many Australian accountants won't touch it.

1. Expat US Tax — Melbourne CBD, Victoria (also North Sydney, NSW)

A specialist US expat tax firm founded in 2011, with offices in Melbourne and North Sydney.

Specialty US federal returns, streamlined filing, ITINs, renunciation, US–Australia cross-border adviceBest for US citizens and green card holders living in Australia

Expat US Tax was set up in February 2011 by Andrew Landin, a lawyer and tax professional who previously worked at Ernst & Young and PwC, and it focuses on Americans living in Australia, the UK and the Middle East. Its Australian team works from offices in Melbourne and North Sydney, and several of its accountants list EA or CPA credentials.

It handles annual US returns, streamlined catch-up filings, ITIN applications and advice on giving up US citizenship. It says it charges less than the Big Four and offers both a face-to-face service and a lower-cost option for simpler returns.

Good to know: Ask which service level fits you — the hands-on option costs more than its lower-cost tier.

2. AmTax — Melbourne CBD, Victoria

A Melbourne US-tax practice run by an IRS Enrolled Agent since 2004.

Specialty Annual US returns, late returns, streamlined procedures, FBAR, renunciation reliefBest for Americans and green card holders living outside the US

AmTax is run by Tameron McDougall, an IRS Enrolled Agent since 2004 who started in US tax in 2000 and founded AmTax in 2015 after 13 years working in the UK. It prepares annual and late US returns, FBARs, Streamlined Foreign Offshore Procedures filings and the relief procedures for certain former citizens.

It suits Americans who want a dedicated US-tax specialist and are happy to keep a separate accountant for their Australian return — AmTax says it does not do Australian tax. The service runs entirely online, with an office in Exchange Tower for appointments.

Good to know: It only does the US side, so line up an Australian accountant too.

Extax was established in Sydney in 2002 and handles US tax for individuals living in Australia: US citizens, green card holders and Australians with US investments. It prepares all US lodgements and represents clients before the IRS when notices or audits arrive.

It is a good fit for Sydney-based Americans with relatively straightforward affairs who want a long-established local specialist, and for Australians who have US shares or property and need to file there.

4. PwC Australia US Tax Advisory — Barangaroo, Sydney, NSW

The Big Four's Sydney-based US tax team for wealthy individuals, families and family offices.

It is the right call when there are trusts, companies, US property or large investment portfolios involved, or when an employer is paying. For a salaried American with an Australian bank account and super, a specialist boutique will be far better value.

Good to know: Worth it for complex structures; overkill for a simple salary-and-super return.

Frequently asked questions

Do Americans living in Australia have to file US taxes?

Yes. The US taxes by citizenship, so US citizens and green card holders file a federal return (Form 1040) each year if their income is above the filing threshold, even if they have lived in Australia for decades. Most owe nothing because the Foreign Tax Credit offsets US tax with the higher Australian tax already paid, or the Foreign Earned Income Exclusion shelters salary.

What is the FBAR and do I need to file one?

The FBAR (FinCEN Form 114) reports your foreign bank and financial accounts to the US Treasury. You must file it if the combined maximum balance of all your non-US accounts was more than US$10,000 at any time in the year — a threshold most Americans with an Australian bank account and super easily pass. It is filed separately from your tax return, online, and penalties for not filing can be severe.

When are US returns due if I live in Australia?

Americans abroad get an automatic extension from 15 April to 15 June to file, and can request a further extension to 15 October, though interest runs on any tax owed from April. Australia's tax year ends on 30 June, so a specialist will usually prepare your Australian return first and use it to complete the US one.

Is Australian superannuation a problem for US tax?

It can be. The US has no clear rule on how super is taxed, and practitioners take different positions on contributions, earnings and reporting (some treat funds as foreign trusts). Australian managed funds and ETFs are usually PFICs under US rules, which have punitive tax and extra forms. This is exactly why a US expat specialist is worth paying for.

I haven't filed US taxes for years — what can I do?

If your failure to file was non-wilful, the IRS Streamlined Foreign Offshore Procedures let you catch up by filing the last three years of returns and six years of FBARs, usually without penalties. Several firms below offer fixed-price streamlined packages. Talk to a specialist before you file anything.

Do I also need an Australian accountant?

If you are an Australian tax resident you also lodge an Australian return. Some US specialists only do the US side, so you may need a local accountant as well — see our best accountants in Sydney. The US–Australia tax treaty and a separate social security (totalisation) agreement help avoid double taxation.
