Introduction: Why Your IRS Online Account Matters More in London Than in Boston
Your IRS online account is the only place where you can see, in real time, what the United States government believes you owe, what it has received and which letters it has already sent you. For an American living in Britain, that matters far more than it does for a neighbour in Boston. Notices go to old US addresses, payments arrive by international wire, and a missed return can sit on your record for years before anyone in London notices. Consequently, the account is often the first honest picture a wealthy expatriate gets of their US position.
At TaxYork, we prepare US and UK returns for investment bankers, company owners and investors who split their financial lives between two tax systems. In our experience, most of these clients have never opened an IRS online account, and many assume they cannot because they have no US phone number, no US driving licence and no US bank. That assumption is wrong. However, the route to access is different from the one the IRS describes for domestic taxpayers, and the account itself has blind spots that matter enormously for anyone with foreign income.
This guide explains how the IRS online account works from Britain in 2026, how to pass identity verification with UK documents, what the account shows and hides, and how to use it when you have missed US tax returns. Furthermore, it covers the power of attorney gap that catches almost every overseas client, and it ends with a worked case study from our own files.
What the IRS Online Account Actually Is
The IRS online account is a secure, individual portal on irs.gov that displays your federal tax record. According to the IRS page on the online account for individuals, you can view balances by tax year, see up to five years of payment history, read digital copies of IRS notices, download transcripts and information returns, and manage payment plans. In addition, you can request an Identity Protection PIN and approve authorisation requests from a tax professional.
Importantly, the account is a window, not a filing system. You cannot file a Form 1040 through it, you cannot lodge an FBAR through it, and it does not interpret anything it shows you. It simply reflects what the IRS has recorded. Therefore, its value depends entirely on how well you read what is there, and on recognising what is missing.
Who Can Open One From Overseas
Any individual aged 18 or over who can verify their identity can create an IRS online account, and the IRS online account FAQs confirm that the service is available to taxpayers with international addresses. You need a Social Security number or an ITIN, a personal email address and a way to receive multifactor authentication codes. Notably, US citizens born abroad who have never lived in America qualify on exactly the same terms as anyone else, provided they hold an SSN.
Setting Up Your IRS Online Account From the UK
The practical barrier for most Americans in Britain is not eligibility but identity verification. The IRS relies on a third-party credential service, ID.me, for its individual accounts, and the IRS guidance on creating an account lists a valid government photo ID, an SSN or ITIN and multifactor authentication as the core requirements. For domestic users, the self-service route checks those details against US credit and financial databases within minutes.
From London, that self-service route usually fails. Your credit file, phone contract and bank accounts are British, so the automated checks have nothing to match. Moreover, the self-service path eventually asks for a US mobile number, which many long-term expatriates no longer have. As a result, repeated attempts through the wrong door can lock you out for a period and create a support ticket that takes weeks to resolve.
The Non-US Route Through ID.me
The correct approach is to tell ID.me at the outset that you live outside the United States. The ID.me guidance for people living outside the US with an SSN instructs you to select the option stating that you do not live in the United States, rather than choosing self-service or a standard video call. You then enter your UK address and your SSN, and you can use an international phone number for multifactor authentication.
After that, you upload your documents and join a video call with an ID.me agent, who checks your name, date of birth, address and SSN against the originals you hold up to the camera. In our experience, clients who prepare properly complete the whole process and reach their IRS online account in one sitting of under an hour. By contrast, those who start on the self-service path and then switch often lose several days.
Documents That Work for Americans in Britain
ID.me accepts either two primary documents, or one primary document plus at least one secondary document. A primary document is a passport, passport card, national identity card or other government photo ID. Therefore, a US passport together with a UK photocard driving licence satisfies the two-primary test for most of our clients. Alternatively, a US passport plus a recent UK bank statement or utility bill, in English and showing your British address, meets the primary-plus-secondary test.
In particular, dual nationals should use the US passport as the lead document wherever possible, because the name and date of birth must match the IRS record attached to your SSN. For those without an SSN, ID.me offers a separate route using a non-US passport, again with a mandatory video call. However, an accidental American with no SSN cannot reach an IRS online account at all until the Social Security number is obtained, which is a separate process we cover in our guide to US tax returns for expats.
Name Mismatches and Married Names
The most common failure we see among high-net-worth clients is a name mismatch. Specifically, many Americans in Britain married after their SSN was issued and now hold a UK driving licence and bank accounts in a married name, while Social Security still holds the maiden name. ID.me will verify the documents, but the IRS will then fail to match the identity to its records. Consequently, the account either refuses to open or opens with no data.
The fix is to update the name with the Social Security Administration first, which from Britain means working through the Federal Benefits Unit at the US Embassy in London. Only after the SSA record changes, and the change flows to the IRS, should you attempt the IRS online account again. Similarly, a hyphenated or double-barrelled surname needs to match exactly across the passport, the SSA record and the name used on your most recent US return.
What Your IRS Online Account Shows You
Once you are in, the IRS online account opens on a summary page showing any balance owed, recent payments and alerts. The IRS tax tip on individual online accounts, published in February 2026, confirms that users can now receive and view more than 200 types of digital IRS notices, check refund and amended return status, and download wage and income documents. For an American abroad, several of these features solve problems that the postal system creates.
Balances, Payment History and Pending Payments
The balance screen breaks down what you owe by tax year, including assessed penalties and accrued interest. Furthermore, the payment history shows every credited payment for up to five years, which is the fastest way to confirm that an international wire actually reached the right year. We routinely use this screen to catch payments applied to the wrong tax period, an error that is common when a UK bank truncates the reference on a wire.
However, paying directly through the account has a catch. The bank-account payment option inside the IRS online account uses the same rails as IRS Direct Pay, and the Direct Pay help page confirms that it needs a US routing number. If your money sits entirely in British banks, you will pay by international wire or card and then use the account only to confirm receipt. Our guide on paying the IRS from a UK bank account explains the wire route and the shortfall trap in detail.
Digital Notices Instead of Lost Post
For expatriates, the notices tab is often the most valuable feature. The IRS posts letters to the last address it holds, and for many Americans in Britain that is a parents' house in Ohio or a flat they left a decade ago. As a result, a balance-due notice, a proposed adjustment or even a statutory notice of deficiency can pass unseen. Inside the IRS online account, you can read digital copies of many notices and opt into paperless delivery for some of them, together with email alerts when something new arrives.
That does not make the post irrelevant. Therefore, you should still update your address with the IRS on Form 8822 after any move, because some letters, including certain legal notices, continue to go by mail. Nevertheless, reviewing the notices tab every quarter would have saved several of our clients from penalties that grew for years simply because nobody opened a letter in America.
Transcripts and Information Returns
The account gives immediate access to account transcripts, return transcripts, record of account transcripts and wage and income transcripts, all of which are also available through the Get Transcript service. Additionally, you can download certain information returns directly, including Forms W-2, 1099-INT, 1099-DIV, 1099-NEC and 1099-MISC. According to the IRS, 2025 wage and income transcripts became available earlier than the usual late-March timeframe this year.
For a UK resident, these transcripts are informative mainly for what they reveal about US sources. They show your US brokerage accounts, US bank interest, US pension distributions and any US-source consulting income. Conversely, they show nothing about your British salary, your ISA or your UK pension, because no British institution files information returns with the IRS in that form. Our detailed guide to IRS wage transcripts for missed US tax returns explains how to read an almost empty transcript correctly.
What Your IRS Online Account Does Not Show
Every IRS online account has blind spots, but for Americans in Britain they are structural rather than occasional. The IRS knows about your foreign life mainly through what you file, and through FATCA data that British banks send via HMRC under the intergovernmental agreement. Crucially, that FATCA data is not displayed in your account. Therefore, an account that looks clean can sit alongside a serious compliance gap.
Your FBAR Record Lives Elsewhere
The FBAR is a Treasury form filed with FinCEN, not the IRS, so no part of your FBAR history appears in the IRS online account. You cannot see whether a prior year's FBAR was received, and you cannot see whether FinCEN has a record at all. Instead, you must keep your own BSA E-Filing acknowledgements, and the FinCEN guidance on reporting foreign bank and financial accounts remains the authoritative source on the filing duty itself. Consequently, a clean IRS account tells you nothing about missed FBAR filings, which is why we always check the two records separately through our FBAR and FATCA compliance service.
Foreign Income, Form 8938 and Treaty Positions
Similarly, the account does not show whether you filed Form 8938, Form 5471, Form 8621 or Form 3520, and it does not flag missing ones. The return transcript shows limited line items from your Form 1040, so you can see that a foreign earned income exclusion or foreign tax credit was claimed, but you cannot tell whether it was calculated correctly. Moreover, nothing in the account tests whether a treaty position under the US-UK convention was properly disclosed.
In practice, that means the account will happily display a zero balance on a return that understated income by several hundred thousand dollars. The IRS may only find the problem years later through FATCA matching, at which point the balance appears suddenly with penalties and interest attached. Therefore, a zero balance in your IRS online account is a necessary signal, never a sufficient one.
Years With No Return at All
When you have simply not filed, the account usually shows nothing for that year. There is no alert saying a return is missing, and there is no balance because nothing has been assessed. However, if a US payer reported income to the IRS, the Automated Substitute for Return programme may eventually prepare a return for you, and at that point an assessed balance appears. We explain how those assessments work, and why they deny foreign tax credits, in our article on substitute for return assessments for Americans abroad.
Using Your IRS Online Account to Fix Missed US Tax Returns
For a client with missed US tax returns, the IRS online account is the first diagnostic tool we use, before a single form is drafted. It tells us which years the IRS believes are open, whether any assessments exist, and whether enforcement has already started. That information determines which route back into compliance is available, and it prevents the costly mistake of filing into a situation you have not understood.
Reading the Account Transcript Before You File
The account transcript for each year, downloadable from your IRS online account, shows transaction codes that reveal the IRS's view of your file. For example, code 150 records a return being filed and assessed, while code 290 shows an additional assessment. Transaction codes associated with substitute returns and examinations indicate that the IRS has already acted without you. In our experience, a single transaction code read before filing has changed the whole strategy for a client more than once.
Specifically, an examination or an existing assessment can affect eligibility for the IRS Streamlined Filing Compliance Procedures, which are generally unavailable to taxpayers already under civil examination. Therefore, checking the account first is not optional. If you are several years behind, our IRS Streamlined filing service begins with exactly this review.
Wage and Income Transcripts as a Reconciliation Tool
Wage and income transcripts in your IRS online account are the IRS's own list of information returns received under your SSN. Consequently, every figure on them must appear somewhere on your reconstructed return, or you invite an automated underreporter notice later. For Americans in Britain, the typical entries are US brokerage 1099-B forms, US bank 1099-INT forms and distributions from a US 401(k) left behind after a move to London.
The 1099-B entry is the most dangerous, because it often reports gross proceeds without cost basis. If the IRS computes tax on the proceeds alone, it treats the entire sale price as gain. Hence, reconciling your own basis records against the transcript is the first job in any reconstruction, and the evidence must be ready before you file.
Protecting Missed Years With an IP PIN
Once you begin filing again, identity theft becomes a real risk, because fraudsters target SSNs attached to dormant filing histories. An Identity Protection PIN is a six-digit number that prevents anyone else from filing a return under your SSN. According to the IRS guidance on getting an IP PIN, the online account is the fastest way to obtain one, and a new PIN is generated every calendar year.
The alternative paper route, Form 15227, is only available if your adjusted gross income is below $84,000 as a single filer or $168,000 on a joint return. For the high earners we represent, that threshold rules it out entirely. As a result, the IRS online account is effectively the only practical way for a wealthy American in Britain to obtain an IP PIN without visiting a Taxpayer Assistance Center in the United States. Remember, too, that the PIN is viewable in the account only from mid-January to mid-November, so retrieve it before your preparer needs it.
The Power of Attorney Gap for Overseas Clients
Most US preparers now expect to authorise themselves digitally. Through the IRS Tax Pro Account, a practitioner submits a power of attorney or tax information authorisation request, and the client approves it in their IRS online account in minutes. For domestic clients, that has almost replaced paper Forms 2848 and 8821.
Why Tax Pro Account Stops at the US Border
However, the IRS limits Tax Pro Account authorisation requests to individuals with an address in a US state or the District of Columbia, and the taxpayer address entered must match IRS records. Consequently, if the IRS holds your London address, as it should, your preparer cannot send you a digital request at all. This single restriction explains why so many Americans in Britain log in, look for the authorisations tab and find nothing waiting.
Moreover, some clients try to solve the problem by reverting to an old US address. We strongly advise against that. It misstates your residence on the IRS record, it can send future notices back to an empty house, and it can undermine the tax home position that supports your foreign earned income exclusion.
Submitting Form 2848 or 8821 Online Instead
The correct route is the traditional Form 2848 or Form 8821, signed by you and submitted by your preparer through the IRS online submission tool for Forms 2848 and 8821. The form is processed onto the Centralized Authorization File in the normal way, and it gives your representative access to your transcripts and the ability to speak to the IRS on your behalf. It does not, however, give them your login.
In addition, never share your ID.me credentials with anyone, including a preparer. The IRS is explicit that only the taxpayer should log into the account. A properly filed Form 2848 gives your representative everything they legitimately need, while shared credentials create a security risk and can invalidate the audit trail if something goes wrong.
Joint Filers and Separate Accounts
Each spouse needs a separate IRS online account. According to the IRS FAQs, both spouses can see balance, payment and tax record information for years they filed jointly, but each sees only their own information for years not yet filed. Similarly, estimated tax payments appear only under the spouse who made them until the joint return is processed.
This matters in mixed-nationality households. A British spouse who is not a US person will not normally have an account at all, even if an election under section 6013(g) has been made to file jointly. Therefore, the American spouse's account becomes the sole window onto the joint record, and payments must be tracked carefully under that SSN.
Case Study: A London Banker's IRS Online Account Review
The following illustrative case is based on the type of situation we see regularly, with names and details changed. Daniel, a US citizen aged 46, is a managing director at an investment bank in London earning around £380,000 a year. He moved from Boston in 2016, filed US returns for his first few years in Britain, and then stopped after 2020 when his previous preparer retired. By September 2026, he had missed US tax returns for 2021 to 2024.
What the Account Revealed
Daniel's first attempt at self-service verification failed because it demanded a US mobile number. We walked him through the non-US route, using his US passport and UK photocard driving licence, and he completed the ID.me video call in about forty minutes. When the IRS online account opened, it showed a balance due for 2021 of $38,940 that he had never heard of.
The account transcript explained why. In 2021, Daniel had sold a legacy US brokerage holding for $180,000, and the broker had reported the gross proceeds without basis. With no return on file, the IRS prepared a substitute return, taxed the full $180,000 as gain after only the standard deduction, and assessed $25,118 of tax. Failure-to-file and failure-to-pay penalties plus interest took the balance to $38,940. Meanwhile, a CP14 balance-due notice and a later CP504 had been posted to his former Boston flat, and the notices tab showed both.
How the Position Was Repaired
Because Daniel's address on the IRS record was in London, we could not send a Tax Pro Account request. Instead, he signed a Form 2848, which we submitted online, and our team then pulled every transcript for 2019 to 2025. His own records showed a cost basis of $142,000, so the true gain was $38,000. Furthermore, as a UK resident he had paid UK capital gains tax at 20 per cent on the same disposal, and under section 865 the gain was foreign-source for credit purposes.
We filed an original 2021 Form 1040 to replace the substitute return, claiming the correct basis and a foreign tax credit that fully offset the 20 per cent US capital gains rate. The only residual liability was the 3.8 per cent net investment income tax of $1,444, which UK tax cannot credit. After recomputed penalties and interest of about $700, the 2021 bill fell from $38,940 to roughly $2,150, a saving of more than $36,000. Subsequently, we prepared his 2022 to 2024 returns, with foreign tax credits covering his UK salary, and filed his outstanding FBARs.
The Lesson for Wealthy Expatriates
Without the IRS online account, Daniel would have discovered the assessment only when the IRS moved to collection. By then, the notice of deficiency window would have closed and the repair would have required audit reconsideration rather than a straightforward original return. Finally, once his returns were current, Daniel obtained an IP PIN through the account and switched eligible notices to paperless, so the same problem cannot recur unseen.
IRS Online Account Security, Scams and Ongoing Housekeeping
A functioning IRS online account is also a target. Criminals send convincing emails and text messages impersonating the IRS, often asking you to verify your identity through a link. The IRS does not initiate contact by email or text to request personal or financial information. Therefore, you should only ever sign in by typing irs.gov into your browser, and you should treat any unsolicited message about your account as suspect.
A Quarterly Review Routine
For high-net-worth clients, we recommend a short review every quarter. Check the balance screen for unexpected assessments, confirm that estimated payments and wires have credited to the correct year, and read any new notices. Additionally, confirm your address on the profile page of your IRS online account after any move within Britain. The whole exercise takes about ten minutes and catches most problems before penalties compound.
Keeping the UK Side Aligned
Your US account is only half of the picture. HMRC's personal tax account is the British equivalent, and it shows your PAYE record, tax codes and payments to HMRC. Consequently, we review both side by side, because UK payment timing drives the foreign tax credit on your US return. Our guide to the HMRC personal tax account for Americans in Britain explains that side in detail.
When to Call the IRS International Line Instead
Some problems cannot be solved online. If ID.me verification repeatedly fails, or if the account shows an assessment you do not understand, the IRS international taxpayer line on +1 267 941 1000 is the direct route, although it is not toll-free and waiting times can be long. In more serious cases, particularly where collection action threatens hardship, the Taxpayer Advocate Service can intervene. The IRS also publishes a useful overview for US citizens and resident aliens abroad.
How TaxYork Can Help
TaxYork provides comprehensive US and UK tax preparation for Americans in Britain, including the diagnostic work that starts with your IRS online account. We help you pass ID.me verification through the correct non-US route, pull and interpret every transcript for the years that matter, and identify assessments, substitute returns and misapplied payments before they grow.
From there, our team prepares any missing US federal returns, FBARs and Forms 8938, alongside your UK Self Assessment where needed, so that foreign tax credits line up across both systems. Furthermore, we file your Form 2848 through the correct overseas route, so we can deal with the IRS on your behalf without ever needing your login. Where treaty positions are involved, our US-UK tax treaty optimisation service ensures that every claim is properly supported.
Conclusion
The IRS online account has become an essential tool for Americans in Britain, but only for those who know how to reach it and how to read it. Access is achievable from London through ID.me's non-US route, using a US passport and British documents, with a video call in place of the domestic self-service checks. Once inside, you gain real-time visibility of balances, payments, notices and transcripts that the postal system routinely fails to deliver abroad.
Nevertheless, the account shows only what the IRS has recorded. It says nothing about FBARs, foreign information returns or the accuracy of your foreign tax credit, and it is silent about years you never filed until an assessment appears. Therefore, treat it as the first step of a compliance review, not the last. If your account shows something you did not expect, or shows nothing where there should be a return, act before the IRS does.
