An IRS letter living abroad is either a bank FATCA letter or a real IRS notice — and each runs a different clock. Here's which one you hold, and what to do next.

An IRS letter living abroad is one of two things: a FATCA letter from your foreign bank asking you to confirm your US tax status, or a notice from the IRS itself. The first means the IRS has not yet contacted you and your best catch-up routes remain open; the second starts a real clock.
Key takeaways
Under the Foreign Account Tax Compliance Act (FATCA), banks and investment platforms outside the United States must identify customers who may be US persons and report their account information onward, either through their local tax authority or directly to the IRS. When your bank finds a US marker in its files — a US birthplace on your passport, a US address or phone number, regular transfers to a US account — it writes to you and asks you to confirm your status, typically by returning Form W-9 (you are a US person) or Form W-8BEN (you are not).
Read the letter precisely, because its source matters. It comes from your bank's compliance department, not from the IRS. Nobody in the US government has opened your file, and consequently every voluntary catch-up route the IRS offers is still available to you.
However, the letter is also a starting gun. Once you return a W-9, your bank reports your name, taxpayer identification number and account details onward — and that information can eventually be matched against the returns and foreign-account reports you have, or have not, been filing.
An actual IRS notice is different in kind, not just in tone. Every genuine notice carries an identifying code (CP or LTR followed by a number), explains why it was sent, and states what you must do and by when. The IRS's own guide, Understanding Your IRS Notice or Letter, lets you look the code up before you panic.
Many notices are routine: a calculation adjustment, a request for a missing form, a balance reminder. Others carry far more weight — a notice about unfiled returns, unreported foreign income, or the opening of an examination. The distinction is critical, because the IRS's most generous catch-up program rewards taxpayers who come forward before the IRS comes to them.
If the only letter on your desk is from your bank, you are in the stronger position. First, check whether you actually have a problem: many recipients are fully compliant and simply need to return the form. If, on the other hand, you have missed US returns or foreign-account reports, this letter is your prompt to fix things on your own terms.
For Americans abroad whose failure to file was non-willful — an honest mistake, or simply not knowing the rules — the Streamlined Filing Compliance Procedures let you catch up on a limited, defined set of past returns and account reports, with far better outcomes than being found first. We cover the mechanics in our guide to the Streamlined Foreign Offshore Procedure and our overview of catching up on missed US tax returns.
The trap is timing. The bank will not wait for you, and once its report is filed, the odds that the IRS reaches you first begin to rise. The streamlined route is only open to taxpayers the IRS has not yet placed under examination — so the moment to use it is now, while the letter in your hand is from a bank and not the government.
A genuine IRS notice changes the playbook. The worst possible response to an IRS letter living abroad is silence: the deadlines in the notice keep running whether or not you are in the country, and ignoring them converts solvable problems into expensive ones.
It also changes your options. Under the IRS's published terms, a taxpayer is not eligible for the streamlined procedures once the IRS has initiated a civil examination of their returns for any year — whether or not that examination relates to foreign assets. In plain terms, an examination letter can close the streamlined door, which is exactly why the bank-letter stage is so valuable.
What should you do instead? Three things, calmly and in order. First, identify the notice code and its response date. Second, engage a cross-border professional — a CPA, Enrolled Agent or tax attorney can be authorized to deal with the IRS on your behalf, which alone removes most of the fear from the process. Third, respond on time and completely, through your representative. Depending on the notice, the right path may be filing the outstanding returns with reasonable-cause explanations, using other IRS submission routes that remain open, or — where there is any suggestion of willfulness — taking legal advice before anything at all is filed.
Often, yes — it depends entirely on which letter you received. A FATCA letter from your bank does not affect eligibility at all. A routine IRS notice — a balance reminder, a filing prompt — is not automatically an examination, and many taxpayers in that position can still qualify; that is a judgment call for a professional who has read the actual notice. An opened civil examination, by contrast, ends eligibility under the program's own terms.
One more gate matters. The streamlined procedures require you to certify, under penalties of perjury, that your conduct was non-willful. That certification is a serious legal statement. Receiving an IRS letter living abroad does not stop you from making it — but you should never sign it without a professional review of your facts. Our streamlined filing service for expats exists for precisely this situation.
Whichever letter you hold, the same short sequence applies. Identify the letter: bank or IRS — and if IRS, which code. Note every date in it. Do not return a W-9, and do not sign any certification, before you understand what the IRS will see once you do. Gather what you can: recent returns if any, account statements, and your travel and residency history. Then get advice from someone who handles these letters every week. If the bank's deadline is tight, ask for a short extension; banks routinely grant them while a customer regularizes their status.
Above all, do not attempt a "quiet disclosure" — silently back-filing old returns as if nothing happened. The IRS explicitly discourages it, and it forfeits the protections the formal programs provide.
We triage IRS and FATCA letters for Americans abroad every week: same-day identification of what your letter actually is, an honest assessment of which routes are open to you, and preparation of the full streamlined or catch-up package — with every filing reviewed and signed by a licensed CPA or Enrolled Agent, never software alone. If a notice needs a response, we draft it; if representation is needed, we arrange it. Book a confidential consultation — confidential, same-day reply — and bring the letter with you.
