Can the IRS put a lien on my house in London?

The statutory lien under IRC 6321 attaches to all property and rights to property of the taxpayer, which in scope includes UK assets. Enforcement is a different question. The Internal Revenue Manual explains that a taxpayer residing abroad is deemed to reside in Washington DC for filing a Notice of Federal Tax Lien, so the public notice sits in a District of Columbia register. HM Land Registry does not record US federal tax liens, so UK conveyancing searches do not surface it.

I missed the thirty day deadline to request a hearing. What can I still do?

Request an equivalent hearing on Form 12153 within the one year period that begins the day after the date of the levy notice, or for a lien the day after the five business day period following the filing. Levy action is generally suspended during it, but the collection statute is not, and the Decision Letter usually cannot be taken to the Tax Court. Also file Form 8822 immediately and pull your account transcripts to confirm what was issued.

Does the ten year collection statute run while I live in the UK?

Not necessarily. The collection period after assessment is ten years under IRC 6502, but IRC 6503(c) suspends it while the taxpayer is absent from the United States for a continuous period of at least six months, and the IRS states the period does not expire before a minimum of six months after the taxpayer returns. Pending instalment agreements, offers in compromise, timely collection due process requests and bankruptcy suspend it too. Read the date from your transcript.

Can my US passport be revoked over a streamlined balance?

Yes, once the debt is legally enforceable and exceeds the threshold, which is 66,000 US dollars for 2026 and adjusts annually for inflation. The IRS issues Notice CP508C and the State Department may deny or revoke the passport, though it may issue a limited validity passport for direct return to the United States. FBAR penalties are excluded from the definition. Certification is reversed within thirty days once the debt is paid or falls below the threshold.

Are FBAR penalties collected the same way as the tax on a streamlined filing?

No. Tax assessed on your returns is Title 26 liability, collected through the federal tax lien and levy machinery described here. FBAR penalties are assessed under Title 31 and sit outside that process, which is why the IRS expressly excludes FBAR penalties from the definition of seriously delinquent tax debt for passport certification. Keep the two exposures on separate ledgers, because their notices, deadlines and collection routes are not the same.

IRS Liens and Levies After a Streamlined Balance

An IRS streamlined filing that reports tax you cannot pay in full does not stay a filing matter for long. Once the returns are processed and the tax is assessed, the account leaves the submission queue and enters collection, where a federal tax lien arises automatically by operation of law, a levy becomes lawful thirty days after a single notice, and the appeal rights that protect you expire on fixed dates whether or not the post reaches you in London. The statutory mechanics are identical for a UK resident and a Manhattan resident. The practical exposure is not, and neither are the traps.

This article is about enforced collection. It assumes the streamlined package has been filed, the tax has been assessed and a balance remains. What follows is the sequence the Internal Revenue Service actually runs, the statutes behind each step, the deadlines that decide outcomes, and an honest account of what all of it means for someone whose home, salary and bank accounts sit entirely in the United Kingdom. Where the practical reach of a mechanism is uncertain, we say so and point at the published source rather than assert a comfortable answer.

What happens to an unpaid balance after an IRS streamlined filing?

The streamlined foreign offshore procedures are not a payment plan. The published instructions at irs.gov/individuals/international-taxpayers/us-taxpayers-residing-outside-the-united-states require three years of income tax returns, six years of FBARs, a signed Form 14653 certifying non-willful conduct, and payment of all tax due as reflected on the tax returns together with all applicable statutory interest on each late payment amount. The penalty relief is conditional on that. The IRS states that eligible taxpayers will not be subject to failure-to-file and failure-to-pay penalties, accuracy-related penalties, information return penalties or FBAR penalties if they comply with all of the instructions. Payment is one of the instructions, not an optional final step.

In the submissions we prepare, the failure mode is rarely a refusal to pay. It is a mismatch of timing. A passive foreign investment company catch-up on a UK fund holding, several years of unreported UK rental profit, or a section 1291 excess distribution can crystallise as one large dollar figure that lands months before a UK property completion or a deferred bonus. The IRS does not hold the account in suspense while that resolves. Topic 201 at irs.gov/taxtopics/tc201 sets out what happens instead: the first notice explains the balance due and demands payment in full, and the unpaid balance accrues interest compounded daily and a monthly late payment penalty up to the maximum allowed by law.

Assessment is the hinge. Before assessment there is a submission under review. After assessment there is a debt, a taxpayer of record, an address of record, and a statutory clock. Every mechanism described below is triggered by that single event, which is why the date of assessment shown on your account transcript is the first thing we pull when a client tells us a balance was left outstanding.

The IRS assesses the tax reported on the streamlined returns and posts it to the account for each year.
It issues a Notice and Demand for Payment, the first balance due notice, to your address of record.
A federal tax lien arises by operation of law under IRC 6321 and is effective from the assessment date under IRC 6322 once the balance is not paid.
Under IRC 6331(a) the account becomes leviable once you have neglected or refused to pay within ten days after notice and demand.
Before the first levy, IRC 6331(d) requires a Final Notice of Intent to Levy at least thirty days in advance, and IRC 6330 requires it to carry notice of your right to a Collection Due Process hearing.
Separately, the IRS may file a public Notice of Federal Tax Lien, which triggers its own appeal window under IRC 6320.
Once the balance exceeds the inflation adjusted threshold, the debt can be certified to the State Department as seriously delinquent.

The lien arises on assessment, before the IRS files anything

This is the distinction almost every article gets wrong. The federal tax lien is created by statute, not by paperwork. The Internal Revenue Manual at irs.gov/irm/part5/irm_05-012-001 puts it plainly: the lien is created by IRC 6321, which is why it is said to be created by operation of law, and IRC 6322 makes it effective from the assessment date and continuing until the liability is satisfied or becomes unenforceable by lapse of time. The IRS page at irs.gov/businesses/small-businesses-self-employed/understanding-a-federal-tax-lien confirms the three conditions: the balance is assessed, a Notice and Demand for Payment is sent, and the taxpayer neglects or refuses to pay in full. Nothing has to be filed anywhere for the lien to exist.

The Notice of Federal Tax Lien is something else entirely. It is the public document that alerts creditors to the government claim, and its legal function is priority. IRC 6323 makes the lien invalid against four categories of competing party until the notice is filed: a purchaser, the holder of a security interest, a mechanic's lienor and a judgment lien creditor. So the lien reaches your property from the assessment date, and the filing decides who ranks ahead of the government if someone else has a claim on the same asset. When the notice is filed the IRS issues Letter 3172, and that letter carries a thirty day window to request a Collection Due Process hearing under IRC 6320.

Getting rid of it follows the same logic. Full payment is the clean exit, and the IRS states that it releases the lien within thirty days after the debt is paid, the timeframe set by IRC 6325. Short of payment there are three partial remedies: a discharge removes the lien from a specific piece of property, covered by Publication 783; a subordination leaves the lien in place but allows another creditor to move ahead of the IRS, covered by Publication 784; and a withdrawal removes the public notice, requested on Form 12277. A withdrawal removes the filing, not the underlying statutory lien.

What does a US federal tax lien actually do to property in the UK?

The scope of the lien is wide. The IRS describes it as protecting the government interest in all your property, including real estate, personal property and financial assets, and attaching to future assets acquired during the duration of the lien. Read literally and applied to a US person, that language reaches a flat in Wandsworth, a stocks and shares ISA, a UK general investment account and shares in a UK trading company. But that is a statement about the legal scope of a claim against a taxpayer. It is not a statement about enforcement, and the two are routinely conflated in expat content.

Look at where the public notice is filed. The Internal Revenue Manual at irs.gov/irm/part5/irm_05-017-002 explains that for the purposes of filing a Notice of Federal Tax Lien, a taxpayer who resides abroad is deemed to reside in Washington DC, so a notice against personal property is filed with the Recorder of Deeds for the District of Columbia, because the situs of tangible and intangible personal property is treated as the residence of the taxpayer when the notice is filed. The consequence for a UK-based filer is concrete. The public record of the lien sits in a District of Columbia register. HM Land Registry does not record United States federal tax liens, and the conveyancing searches run on a London property do not query the Recorder of Deeds for the District of Columbia.

So the honest position is this. A filed Notice of Federal Tax Lien does not, by itself, cloud the title to your UK home in the way it clouds title to a house in Connecticut. Where it bites is at every point where your affairs touch the United States: a US brokerage or bank account you never closed, a US rental property, US source wages or director fees, a US credit application, a future relocation or an acquisition of US assets, and any transaction where a US counterparty or a lender with US compliance obligations runs a United States public records search. Whether a particular UK bank or counterparty takes notice of a US filed lien is a commercial question rather than a legal one, and no IRS publication addresses it. We do not assert an answer we cannot source.

None of this is a reason to reorganise where assets sit. It is the opposite. The lien continues until the liability is satisfied or becomes unenforceable by lapse of time, the balance compounds daily, and the mechanisms that do reach a UK resident, described below, are the ones that damage a professional life rather than a balance sheet. The correct response to a streamlined balance is to resolve it on published terms, not to move it.

What can the IRS levy, and what has to happen first?

A levy is the seizure itself. The IRS defines it at irs.gov/businesses/small-businesses-self-employed/levy as the legal seizure of your property to satisfy a tax debt, and states that it can garnish wages, take money in your bank or other financial account, and seize and sell vehicles, real estate and other personal property. On a bank levy the funds in the account are held and after twenty one days sent to the IRS, which is the only meaningful window a taxpayer has to intervene once a levy has landed.

The procedural conditions are set out at irs.gov/businesses/small-businesses-self-employed/what-is-a-levy. The IRS will usually levy only after four requirements are met: the tax was assessed and a Notice and Demand for Payment sent; you neglected or refused to pay; a Final Notice of Intent to Levy and Notice of Your Right to A Hearing was sent at least thirty days before the levy; and advance notification of third party contact was issued. The delivery rule is the one that matters abroad. That final notice may be given to you in person, left at your home or usual place of business, or sent to your last known address by certified or registered mail, return receipt requested. The Internal Revenue Manual at irs.gov/irm/part5/irm_05-011-001 confirms that the notice is valid when sent to the last known address whether or not it is actually received, and that where collection is in jeopardy property can be levied immediately after a demand for immediate payment.

For a filer whose life is in the UK, the realistic levy surface is narrower than the lien and is defined by US touchpoints.

US bank and brokerage accounts, including the dormant ones people keep open after moving to London.
US source wages, director fees or self-employment payments made by a US payer.
US real estate and the rents arising from it.
Federal payments and any US tax refund on another year.
Funds held at a domestic branch of a foreign financial institution, which the IRS lists among its international collection tools at irs.gov/irm/part5/irm_05-021-003.
Payments routed through a US financial institution on their way to you.

What is not straightforward is a levy served on a UK bank with no US presence. The IRS international collection guidance leans on treaty assistance, on property situated in the United States and on court remedies, rather than on direct service of a levy abroad, and that emphasis tells you where the practical limit sits. One further separation matters here. Everything above is Title 26 machinery for internal revenue taxes. FBAR penalties are assessed under Title 31 and are not collected through the tax lien and levy process described in this article, which is why the IRS passport page expressly excludes FBAR penalties from the definition of seriously delinquent tax debt.

Does HMRC collect US tax for the IRS?

No. The IRS can make a Mutual Collection Assistance Request, described at irs.gov/irm/part5/irm_05-021-003 as a request for assistance from certain treaty partners to collect taxes owed by individuals residing or holding assets in the treaty country. The Manual identifies exactly six countries whose income tax treaties with the United States contain mutual collection provisions: Canada, Denmark, France, Japan, the Netherlands and Sweden. The United Kingdom is not among them. There is no published route by which the IRS asks HM Revenue and Customs to use its domestic collection powers to recover a United States income tax debt.

Do not read that as an information gap. Exchange of information and collection assistance are different things. Account data flows to the IRS under FATCA and under the exchange of information provisions of the US-UK treaty, so the IRS can be very well informed about UK accounts it has no direct means of levying. In practice we see the two facts arrive together: a client is contacted about assets the IRS clearly already knows about, and simultaneously discovers that the enforcement pressure is being applied through channels that have nothing to do with the UK.

Those channels are the ones to plan around. Passport certification, levies on anything US situated, the compounding balance, the lien attaching to future acquired property, and the collection statute that may not be running at all are all fully available to the IRS against a UK resident. The absence of a collection assistance article in the treaty changes the geography of enforcement. It does not change the debt.

Collection Due Process: the thirty day door and the one year door

Collection Due Process is the taxpayer protection built into the collection statutes, and it is time-limited. The IRS Collection Due Process FAQs at irs.gov/appeals/collection-due-process-cdp-faqs identify the two notices that carry the right: Letter 3172 when a Notice of Federal Tax Lien is filed, and LT-11 or Letter 1058 as the Final Notice of Intent to Levy. The request is made on Form 12153, Request for a Collection Due Process or Equivalent Hearing, within thirty days of the notice.

A timely request buys three things, set out in the Appeals manual at irs.gov/irm/part8/irm_08-022-004. Collection by levy is suspended in most timely CDP levy hearings, with exceptions for disqualified employment tax levies, state income tax refund levies and federal contractor levies. The collection statute is suspended under IRC 6330(e) from the date the IRS receives the timely request until the determination from the Independent Office of Appeals becomes final, including any court appeals. And the resulting Notice of Determination can be petitioned to the United States Tax Court.

Miss the thirty days and you are not finished, but you have a weaker instrument. The same manual provides for an equivalent hearing, requested within the one year period beginning the day after the date of the CDP levy notice, or for a lien within the one year period beginning the day after the end of the five business day period following the filing of the notice. Levy action is generally suspended during an equivalent hearing. The collection statute is not suspended. And an equivalent hearing Decision Letter cannot generally be petitioned to the Tax Court, except on spousal relief under IRC 6015, abatement of interest under IRC 6404(h), or the timeliness of the CDP request itself.

There is a third route, the Collection Appeals Program, requested on Form 9423. It is faster and covers lien filings, levies, seizures and the rejection or termination of an instalment agreement, but Appeals decides only whether the collection action was appropriate. It does not consider collection alternatives, and its decision cannot be taken to court. In a CDP or equivalent hearing you can put a great deal more on the table.

Collection alternatives, including an instalment agreement, currently not collectible status or an offer in compromise.
Whether the lien filing or proposed levy is appropriate and no more intrusive than necessary.
Spousal defences, where relevant.
Procedural verification that applicable law and administrative procedure were followed, including whether the notices were properly issued.
The underlying liability, but only where you had no prior opportunity to dispute it, which is rarely available on a streamlined balance because the figures were self-reported on your own returns.

The notice problem: last known address and the deadline you never saw

Almost every enforced collection case we are asked to unpick for a UK resident starts with a notice that was never read. The rule is unforgiving. Treasury Regulation 301.6212-2 defines the last known address as the address on your most recently filed and properly processed return, unless you have clearly and concisely notified the IRS of a change of address. A notice properly mailed to that address is legally effective whether or not it reaches you. The Internal Revenue Manual states the same point directly for levy notices. The thirty day CDP clock therefore starts on the date of the notice, not on the date you learn of it.

Three features of expat life make this worse than it is for a domestic taxpayer. First, the address on a streamlined package is the address you had when the package was assembled, and assembly to assessment can span many months during which people move. Second, the safety net the IRS uses does not work here: the IRS may update your address of record from the United States Postal Service National Change of Address database, and a move from one London postcode to another will never appear in it. Third, certified or registered mail to a UK address is delivered against a signature at a door nobody is answering on your behalf, and the item is returned rather than forwarded.

The fix is administrative and cheap. The IRS lists the accepted methods at irs.gov/faqs/irs-procedures/address-changes: Form 8822, the address on your next filed return, a signed written statement to the office where you last filed, oral notification with identity verification, or the postal database. It asks for four to six weeks for a change of address request to fully process. In the returns we prepare, the current UK address goes on every return in the streamlined package, and Form 8822 is filed separately the moment a client moves, because the return sitting in a processing queue is not yet a properly processed return.

If a deadline has already gone, work in this order. Pull account and notice transcripts for every year, because the issue dates on the transcripts fix which doors are still open. If you are inside the one year window, file Form 12153 requesting an equivalent hearing. File Form 8822 immediately so the next notice arrives. If a levy is already in place, request its release and use the twenty one day bank holding period. Consider a Collection Appeals Program request on Form 9423 where the complaint is that a specific action was inappropriate. And where the IRS process itself has caused hardship, the Taxpayer Advocate Service can be approached on Form 911.

Does the ten year collection statute run while you live in the UK?

This is the point on which expat commentary is most often misleading. The headline rule is real: the Internal Revenue Manual at irs.gov/irm/part5/irm_05-001-019 states that the length of the period for collection after assessment of a tax liability is ten years, the Collection Statute Expiration Date under IRC 6502. What is usually omitted is what suspends it.

IRC 6503(c) suspends the running of the collection period while the taxpayer is absent from the United States for a continuous period of at least six months, and the same Manual section states that the collection period does not expire before a minimum of six months after the taxpayer returns to the country. For a US citizen who has lived in London for a decade without a six month gap, that is not a technicality. It means the assumption that the debt quietly expires ten years after assessment cannot be relied on at all, and it is the single most important reason not to treat waiting as a strategy.

Other suspensions stack on top. The period is suspended while an instalment agreement request is pending and for thirty days after a rejection plus any appeal, while an offer in compromise is pending and for thirty days after rejection plus any appeal, from receipt of a timely CDP request until the Appeals determination becomes final, during bankruptcy and for six months afterwards, during innocent spouse consideration, and during military service plus a further 270 days. The practical instruction is simple: never estimate a collection statute date. Read it from the transcript and have it checked.

Passport certification for seriously delinquent tax debt

For a UK-based professional this is usually the mechanism with real teeth. The IRS page at irs.gov/businesses/small-businesses-self-employed/revocation-or-denial-of-passport-in-case-of-certain-unpaid-taxes defines seriously delinquent tax debt as legally enforceable unpaid federal tax debt, including assessed penalties and interest, above a threshold that is adjusted annually for inflation. The threshold is 66,000 US dollars for 2026 and was 64,000 US dollars for 2025. When the IRS certifies a debt it mails Notice CP508C by regular mail to your last known address, and the State Department will not issue a passport and may deny an application or revoke an existing passport. For a taxpayer overseas, the State Department may issue a limited validity passport good only for direct return to the United States.

The exclusions matter. FBAR penalties and child support are outside the definition, as are debts covered by an approved instalment agreement, an accepted offer in compromise, a Department of Justice settlement, a timely requested collection due process hearing, or a pending innocent spouse request. The IRS also states it will not certify taxpayers whose accounts are currently not collectible due to hardship, who have a pending instalment agreement or offer in compromise, who are identified victims of tax-related identity theft, who are in bankruptcy, who are in a federally declared disaster area, or who are serving in a designated combat zone.

Reversal is quicker than most people expect. The IRS reverses the certification and notifies the State Department within thirty days when the debt is fully satisfied, becomes legally unenforceable, falls below the threshold, or the certification is found to be erroneous, and issues Notice CP508R. Where speed is needed, the IRS asks the taxpayer to say that travel is scheduled within forty five days or that they live abroad. In practice, paying a balance down just below the threshold is a legitimate and frequently used way to unlock travel while a longer term arrangement is negotiated, and a US citizen generally needs a valid US passport to enter the United States regardless of any other nationality held.

Currently not collectible and offers in compromise

Currently not collectible status is a temporary suspension of collection where the IRS accepts that you cannot pay at present. It requires full financial disclosure and it is not forgiveness. Topic 201 states that interest and the monthly late payment penalty continue to accrue while an account is reported currently not collectible, and the account is reviewed as circumstances change. It also does not prevent the IRS from protecting its position by filing a Notice of Federal Tax Lien.

An offer in compromise is the settlement route. Topic 204 at irs.gov/taxtopics/tc204 sets out three grounds: doubt as to liability, doubt as to collectibility, and effective tax administration, the last applying where the tax is legally owed and collectible but payment in full would create economic hardship or would be unfair and inequitable. You must have filed all required returns, received a bill for at least one debt included in the offer, and made required estimated payments. The application fee is the amount stated on Form 656. A lump sum offer payable within five months requires a nonrefundable payment equal to twenty percent of the offer amount; a periodic payment offer is six or more monthly instalments within twenty four months and requires the first instalment with the form. Acceptance commits you to five years of full compliance, and under IRC 7122(f) an offer not rejected within twenty four months of submission is deemed accepted.

Be realistic about which of these fits our readership. Doubt as to collectibility is a function of realisable assets and future income, and a UK-resident business owner, investor or banker with substantial equity, a London property and a strong earnings profile will rarely present an offer the IRS can accept. Effective tax administration is narrow. For most people carrying a streamlined balance, the honest set of outcomes is payment, a structured arrangement, or the enforced collection sequence described above.

A worked example of how a streamlined balance turns into a levy

The following figures are illustrative and are used only to show the sequence. A US citizen living in London, senior at an investment bank, files a streamlined foreign offshore submission covering three years of returns and six years of FBARs, with a passive foreign investment company catch-up on UK fund holdings. The assessed tax and statutory interest come to 180,000 US dollars. He pays 120,000 US dollars with the submission and intends to clear the remaining 60,000 US dollars from the proceeds of a UK property sale expected within a few months. During that period he moves from one London flat to another and does not tell the IRS.

The returns are assessed. A Notice and Demand for Payment goes to the address shown on the returns. The property sale slips. Interest compounds daily on the unpaid amount, and the balance grows. Some months later a Final Notice of Intent to Levy and Notice of Your Right to A Hearing is sent by certified mail to that same address, is not delivered and is returned. The notice is nevertheless valid, so the thirty day window to file Form 12153 opens and closes without him knowing it existed. He learns of the position when a dormant US brokerage account he had forgotten about is levied and the funds are held for twenty one days, and when the accrued balance crosses the certification threshold and a CP508C is issued.

None of that is unrecoverable. Inside the one year window he can request an equivalent hearing on Form 12153, which generally suspends levy action while it is considered, though it does not suspend the collection statute. Form 8822 fixes the address so the next notice arrives. A levy release can be requested, and the twenty one day holding period is the moment to act. Paying the balance below the seriously delinquent threshold triggers reversal of the passport certification, with the IRS notifying the State Department within thirty days. What cannot be recovered is the right to take a determination to the Tax Court, and that was lost purely to an out of date address.

How we keep a streamlined balance out of enforced collection

Model the full liability, including statutory interest, before the streamlined package is filed, so the payment obligation is known rather than discovered.
Put the current UK address on every return in the package, and file Form 8822 separately on any move, allowing the four to six weeks the IRS asks for.
Register for and monitor IRS account transcripts for every year in the submission, so notices are seen even when the post fails.
Diarise the thirty day CDP window from the date on any Letter 3172, LT-11 or Letter 1058, and the one year equivalent hearing window behind it.
Read the collection statute date from the transcript rather than assuming ten years, given the suspension for continuous absence from the United States.
Track the balance against the current seriously delinquent tax debt threshold before travel is booked.
Keep Title 26 tax and Title 31 FBAR exposures on separate ledgers, because they are collected under different authority.
Where a balance cannot be cleared, engage on published terms early, because almost every alternative works better before a levy than after one.

A streamlined submission is a compliance exercise, and it is only finished when the tax and the statutory interest are paid. Where a balance remains, the file becomes a collection matter governed by statutes with hard dates, and the single greatest determinant of the outcome for a UK-resident filer is whether the notices reach a live address in time to use the rights they carry. If you are preparing or repairing a submission, our work on the streamlined route is at us-uktax.com/irs-streamlined-filing and us-uktax.com/streamlined-foreign-offshore-procedures, and the wider US filing service is at us-uktax.com/us-tax-services. Bring the transcripts, the notices and the dates, and the position is usually more repairable than it looks.
