Covering the specific tax reporting requirements dual citizens face
Exceptional accuracy
Every return is prepared and reviewed by seasoned tax advisors
As a dual citizen, you're required to file a US federal tax return every year. TFX prepares your return, covering your foreign income, foreign accounts, and any forms your situation requires.
You moved abroad, had no US-source income, and assumed no US return was needed. Or you've just found out that US citizens must file regardless of where they live or where their income comes from.
A company you own abroad, rental income, or growing investment portfolio means more forms and more interaction between different tax systems.
A W-9 or FATCA request from your local bank is often the moment dual citizens first discover they have US reporting obligations. We help you understand what it means and what to do next.
ISAs, RRSPs, superannuation, or other pension accounts – dual citizens often hold assets across two countries, each with specific US reporting requirements that go beyond the return itself.
Whether you've just naturalized, acquired a second citizenship, or recently obtained a US passport – a new status means new questions about what you're required to file and when.

“I file every year as a dual citizen – but managing income and accounts across two countries is more than I can handle alone.”

“I didn't know I had to file. Now I do – and I want to get compliant without penalties.”

“I have a company and accounts abroad. I need a specialist who understands how to report them in the US.”

“My bank flagged my US citizenship. I don't know if I need an FBAR, FATCA form, or both.”

“I'm selling property or winding down a company. I need to know the US tax impact before I act.”
Tax filing for dual citizenship can involve more than a standard US return. We prepare your federal and applicable state returns, report worldwide income, apply relevant exclusions and credits, and complete the international forms required for your situation.
For dual citizens who have missed years of US tax returns, the streamlined foreign offshore procedure offers a structured, penalty-free path back to compliance. TFX has completed 2,200+ of these submissions.
Dual citizens with foreign financial accounts above the reporting threshold must file an FBAR (FinCEN 114) each year. TFX prepares your FBAR alongside your return as part of one coordinated submission.
Guidance on foreign tax credits, filing elections, and how cross-border decisions – a property purchase, a new business, a move between countries – affect your US obligations before they show up as a problem in your return.
Dual citizens with foreign assets above set thresholds must report them on Form 8938 under FATCA — separate from, and in addition to, FBAR. We assess your exposure and file it alongside your return as part of one coordinated submission.
Foreign mutual funds, ETFs, and pooled investments – as well as pensions such as a UK SIPP, Australian superannuation, or Canadian RRSP – may qualify as Passive Foreign Investment Companies, triggering Form 8621 reporting that goes beyond a standard return.
If you're planning to make a significant change to your citizenship status, your US tax filings generally need to be fully current first – including any outstanding returns and FBARs. We can get you compliant and guide you through the full process, step by step.
I've been living in the US for the last couple of years as a dual citizen and was looking for help catching up on my taxes and filing my ongoing taxes going forward. I found Taxes for Expats really helpful in understanding all the processes involved, and the service I received was great. I know there are alternatives out there, but for me, Taxes for Expats has been fantastic.
I'm a UK-US dual citizen living in London. I've used TFX for the past year – they helped me file the Streamlined Offshore Compliance procedures, and I had a really positive experience. They have great customer service, quick response times, and a well-designed website and questionnaire that make submitting your tax information very seamless. I've recommended the service to friends and will continue to do so – I think they have one of the best services in the tax preparation market.
I am a dual US/UK national living in the UK for the past 9 years. TFX has filed my US tax returns for several years - they are a service I definitely trust and are well worth the money! They are responsive to questions, helpful and efficient. Will use forever!
I've been using Taxes for Expats for over four years now and there's a reason why I keep returning. Their tax questionnaire platform is easy to use and breaks things down into manageable steps. They work with you to maximize deductions and understand the complexity for dual-nationals/people working abroad. They're really easy to communicate with; I like that I can text them and don't have to pick up the phone (millennial!).
I have been living in Italy for many years and have dual citizenship. Preparing the tax documents and filing returns was always complicated for me. I started working with Taxes for Expats in 2015. I had back taxes and bank accounts that had to be reported from 2011 and they helped me get through it all. I have been coming back to them every year since then! They are very good about reminding me of deadlines and filing extensions. I have recommended them to other expat friends.

Trusted by dual citizens with US tax obligations worldwide – for annual tax filing, catch-up cases, and complex cross-border situations.
Worldwide income, foreign account reporting, and multi-jurisdiction complexity handled daily.
We prepare and file your return and required reporting, handling the process from start to finish.
Yes. US citizens must file an annual US tax return regardless of where they live or what other citizenship they hold. Holding a second passport does not remove US filing obligations – the US taxes its citizens based on citizenship, not residency.
It depends on your situation – the country you live in, your income sources, and how your return is structured all affect the outcome. Foreign tax credits and income exclusions can reduce or eliminate US tax liability entirely. A CPA will review your specific situation and give you a clear picture before any work begins.
This is more common than you might expect, and there is a defined path forward. Depending on your situation, you may qualify for one of the IRS offshore compliance programs and catch up without penalties. TFX will review your full situation – filing history, income, and foreign accounts – and recommend the right approach before any work begins.
Dual citizens with foreign financial accounts – bank accounts, investment accounts, pensions – that collectively exceed $10,000 at any point during the year are generally required to file an FBAR (FinCEN 114) each year. This is a separate obligation from the tax return, with its own rules, deadlines, and penalties for non-compliance.
No. Dual citizenship does not change your US tax obligations.
Yes, in many cases. The US allows dual citizens to apply foreign tax credits and exclusions, and benefit from relevant tax treaty provisions – all of which are designed to prevent the same income from being fully taxed twice.
This is a common gap, and the right approach depends on your specific history and circumstances. TFX can review your accounts and confirm what years require reporting. In many cases there is a structured way to bring FBAR filings up to date.
A foreign company or holding structure may require Form 5471. Certain foreign funds can trigger PFIC reporting. Foreign pensions, ISAs, and retirement accounts each carry specific US reporting treatment. A CPA will review your full picture and confirm what applies.
Dual citizens often need someone who understands how US obligations interact with the rules of a second country, including treaty positions, foreign account reporting, and coordinating filings across jurisdictions. TFX CPAs specialize in exactly this – and a free consultation is the fastest way to understand what your specific situation may require.
