Free tools for US expat taxes.
Quick answers to the questions that send US citizens abroad down a rabbit hole — is this fund a PFIC, do I have to file FBAR, what does the §1291 regime actually cost. No account, no email.

US expat tax calculator
The whole picture in one pass — the return, the FBAR, Form 8938, PFICs, foreign companies and whether a Streamlined catch-up may be relevant. Each answer comes back with the reason it appeared.
Start with your question
What are you trying to find out?
Every tool below answers one question well. If you know your problem but not which calculator it belongs to — which is most people, and five of these say “PFIC” on the tin — start here instead of with the grid. Grouped by the problem, not by the form.
Tax estimate and the yearly return
Whether you owe anything, which relief fits, and which forms the year needs.
Will I owe US tax, and which forms do I have to file?
An outlook on the federal tax for your income band with and without the exclusion and the credit, then the return, the FBAR, Form 8938, PFICs and whether a catch-up may be relevant — each with the reason it appeared.
Should I use the FEIE or the foreign tax credit?
A directional read on which one fits your income and foreign tax paid. They are not interchangeable and the wrong choice is expensive to unwind.
How much can I exclude with the FEIE?
The Form 2555 exclusion for your income and qualifying days, prorated if you were only abroad part of the year.
Do I pass the 330-day test?
Counts your full days abroad and finds the best 12-month window — the window is a choice, and the wrong one fails a test you would otherwise pass.
I am self-employed or freelancing abroad
The FEIE does not remove self-employment tax. This estimates what is left, and whether a totalization agreement covers you.
When is everything actually due?
The expat dates differ from the domestic ones — an automatic June extension, a separate FBAR cutoff — with the days remaining for each.
Foreign accounts and reporting
Do I have to file an FBAR?
Which of your accounts count — joint, signature-only, a pension with a cash value, a fintech balance — and whether their combined peak crosses the line. No balances typed; a band is enough.
Where do my balances land against both thresholds?
Enter the actual figures and run the FBAR test and the Form 8938 test side by side — they are different tests with different numbers, and living abroad raises one of them.
What about my Revolut or Wise account?
These apps run US and non-US entities, so the same app is a foreign account for one person and not for another. Settles that first, then the thresholds.
Foreign funds, ETFs and Form 8621
Five tools answer five different questions here. This is which one is yours.
Is my fund a PFIC?
Screens one fund or ETF by name, ISIN or domicile. Start here if you have a single holding you are unsure about.
I have several foreign ETFs
Takes the whole portfolio at once — typed in or imported from a broker CSV — and runs it through the same engine the paid package uses.
I sold a foreign fund, or received a distribution
A sale or an excess distribution is what triggers the §1291 calculation: the tax allocated back across your holding period, plus daily IRS interest.
How much could PFIC filing cost?
Prices the preparation work from your holdings and years. This one never computes tax — it answers the money question only.
How complicated is Form 8621 going to be?
Rates the difficulty rather than the price: missing cost basis, prior elections, how many years and how much reconstruction.
Retirement and pensions
What do I report for my foreign pension?
A pension can reach the FBAR, Form 8938, Form 8621 and Form 3520 at once, and which ones depend on the plan's legal form rather than its country.
Do I pay into US social security as well as my country's?
Whether your country has a social-security agreement with the US, what it does to self-employment tax, and what a certificate of coverage is for.
Years behind, or never filed
I am behind on US filings — what now?
Reviews the published Streamlined criteria against your facts, and says where a question is yours to certify or a professional's to settle.
Which catch-up route fits me?
There is no IRS programme by that name — there are five routes, and the wrong one costs years or penalties. This sorts your situation into the right one before you start any of them.
I have never filed at all
What actually happens, and how to tell which of the three catch-up procedures fits before you start any of them.
Complex situations
A company, an inheritance, a renunciation — each brings its own return with its own deadline.
I own a company abroad
Maps ownership and legal form to the information returns in play — Forms 5471, 8858, 8865 — which are separate from anything personal.
I received an inheritance or a large gift from abroad
Usually no US tax on the money itself — but Form 3520 above the reporting thresholds, on its own deadline, with a penalty for silence that is a share of the amount. The thresholds and the deadline, explained.
I'm thinking about giving up US citizenship
Whether you would be a covered expatriate, what Form 8854 asks, and what has to be filed before the appointment — the three tests, one at a time.
Ready to move
Not a calculator — the routes for someone who already knows what they need.
I want a written plan for my year
The same questions as the calculator, saved: a filing sequence, the documents to gather, and the package or route your year needs — carried into anything you buy after it.
I want to prepare my return
Start a free draft. You see the on-screen result before anything is paid for or generated.
I already have an accountant
Most preparers do not handle Form 8621. The CPA Export hands them the computed PFIC schedules to file with your return.
