Introduction: Why the Collection Appeals Program Matters to Americans in Britain
The collection appeals program is the IRS fast-track route for challenging a lien, a levy, a seizure or a rejected payment plan before the damage becomes permanent. For Americans living in Britain, it is often the quickest way to freeze enforcement against US brokerage accounts, US rental income or a pending tax refund. Moreover, it works on a timetable measured in business days, not months.
Most guides to the collection appeals program assume the taxpayer lives in Ohio, collects post from a US letterbox and can phone the IRS during American office hours. Our clients live in London, Edinburgh and the Home Counties, and they typically learn about a levy only when a US custodian freezes an account. Therefore, this guide explains the procedure from the position of a British-resident American, including the time-zone problems, the foreign postmark trap and the assets the IRS genuinely can and cannot reach.
How the Collection Appeals Program Differs From Other IRS Appeals
The collection appeals program, usually shortened to CAP, is an administrative appeal heard by the IRS Independent Office of Appeals. It sits alongside, rather than replaces, the statutory Collection Due Process hearing. Furthermore, CAP covers a wider range of enforcement actions than any other collection appeal, yet it offers no route to court afterwards. Understanding that trade-off is the single most important decision point in any IRS collection dispute.
Who This Guide Is Written For
We wrote this guide for high-net-worth Americans and dual nationals in the United Kingdom who carry an IRS balance. Typically, that balance arose from missed US tax returns, an audit adjustment, or an installment agreement that lapsed after a bonus year. In addition, it covers accidental Americans who discovered their filing obligations late and now face collection notices on assessments they never expected.
What the Collection Appeals Program Covers
The collection appeals program reaches almost every enforcement step the IRS Collection function can take. According to IRS Publication 1660, Collection Appeal Rights, you may use it before or after the IRS files a Notice of Federal Tax Lien, and before or after it levies or seizes property. Additionally, it covers the rejection, modification or termination of an installment agreement.
Liens, Withdrawals, Discharges and Subordinations
You may appeal a proposed lien filing, the actual filing, and every subsequent refiling. Furthermore, the collection appeals program covers denied requests to withdraw a lien, and denied discharges, subordinations and certificates of non-attachment. For an American in Britain who is refinancing a US property or selling a US condominium, a denied discharge can block completion. Consequently, CAP is frequently the fastest way to rescue a transaction with a deadline attached.
Levies, Seizures and Wrongful Levy Claims
You may appeal a levy on wages, bank accounts or other property either before or after it happens. Similarly, you may appeal a seizure at any point before the property is sold. Once proceeds reach the IRS, you may also appeal a denied request for their return. For levies made on or after 23 March 2017, section 6343 of the Internal Revenue Code gives you two years from the levy date to request that return. Notably, third parties, such as a non-US spouse whose joint account was levied, can use the same route after a denied wrongful levy claim under IRS Publication 4528.
Rejected, Modified and Terminated Installment Agreements
Installment agreement disputes are where the collection appeals program earns its reputation. You may appeal when the IRS rejects a proposed payment plan, proposes to modify an existing one, or moves to terminate it. For wealthy clients with lumpy income, termination after a single missed payment during a liquidity crunch is common. As a result, the ability to put that termination in front of an independent Appeals officer within days is valuable.
The Critical Limits of the Collection Appeals Program
Every advantage of the collection appeals program comes with a matching restriction. Publication 1660 states plainly that you cannot challenge the existence or amount of your tax liability in CAP. Moreover, you cannot go to court if you disagree with the Appeals decision. The decision binds both you and the IRS, and providing false or incomplete information voids it entirely.
You Cannot Dispute the Tax Itself
If your balance arose from a substitute for return that ignored your UK tax credits, CAP is the wrong tool for correcting it. Instead, you need audit reconsideration, an amended return or, where rights remain, a Collection Due Process hearing. Our guide to IRS audit reconsideration for Americans in Britain explains how to reopen an inflated assessment. Therefore, the correct sequence is often to fix the liability first and then use the collection appeals program to manage enforcement on whatever remains.
No Tax Court, No Second Bite
The finality of CAP is its sharpest edge. Specifically, a Collection Due Process determination can be reviewed by the US Tax Court, whereas a CAP determination cannot. In addition, if you appeal an installment agreement termination before it takes effect, you may not appeal the same decision again once termination happens. Accordingly, you should prepare a CAP submission as though it is your only chance, because in practice it usually is.
Offers, Penalties and Other Excluded Disputes
Several collection disputes sit outside the collection appeals program entirely. A rejected offer in compromise, a proposed trust fund recovery penalty and a denied penalty abatement request follow the protest procedure instead. Likewise, penalties for a missed FBAR filed with FinCEN are assessed under Title 31 rather than the Internal Revenue Code, so they follow a separate collection path. For missed FBAR exposure, our FBAR and FATCA compliance service addresses the reporting failure itself.
Collection Appeals Program Versus Collection Due Process
The choice between the collection appeals program and Collection Due Process shapes everything that follows. Collection Due Process, or CDP, is a statutory hearing triggered by specific notices, principally the final notice of intent to levy and the notice of lien filing. By contrast, CAP is available for a broader list of actions and at almost any stage of enforcement.
Speed Against Protection
CAP is fast. The Appeals manual at IRM 8.24.1 sets a goal of deciding cases within five business days of receipt. CDP, however, typically takes several months, and the IRS Collection Due Process FAQs confirm that a timely CDP request suspends levy action and the collection statute throughout. Consequently, CDP buys time and preserves court review, while CAP buys a quick answer.
Deadlines That Do Not Overlap Neatly
You have 30 days from a CDP notice to request a full hearing on Form 12153. For a lien, the IRS must notify you within five business days of filing, and your 30 days run after that period. If you miss that window, an equivalent hearing remains available for one year, but it carries no Tax Court review. Meanwhile, CAP deadlines are counted in business days from a manager conference. Our separate guide to Collection Due Process hearings for Americans in Britain covers the statutory route in depth.
When We Recommend Each Route
In our experience, CDP is the better choice whenever a formal notice is still within its 30-day window and the underlying liability is doubtful. Conversely, the collection appeals program is the stronger choice when the liability is accepted, a levy has already landed, or a revenue officer has rejected a reasonable payment plan. Furthermore, the two are not mutually exclusive, because a lien appeal under CAP does not waive CDP rights on a later levy notice.
How to File a Collection Appeals Program Request From the UK
The procedure depends on who took the action you dispute. The IRS Form 9423, Collection Appeal Request and Publication 1660 describe three tracks: a notice or telephone contact, a revenue officer, and an installment agreement decision. Importantly, each track has its own deadline, and the shortest is measured in hours rather than weeks.
When Your Only Contact Has Been a Notice or a Call
If you have only received a notice or a telephone call, you ring the number on the notice and explain which action you dispute and why. You must also offer a solution, such as a payment proposal. If you cannot agree, the employee must refer you to a manager, who will speak to you then or return your call within 24 hours. If the manager also disagrees, the case goes to Appeals, and you do not have to put the request in writing. For a London caller, that means planning calls for early afternoon UK time, when US eastern offices open.
When a Revenue Officer Is Assigned
Revenue officer cases move faster and demand more discipline. First, you must request a conference with the revenue officer's Collection manager. Next, you must tell the officer or manager within two business days after that conference if you intend to appeal. Finally, Form 9423 must be postmarked within three business days of the conference, or collection resumes. If you request a conference and nobody contacts you, the form should be received or postmarked within four business days of your request. After a seizure, you must appeal to the Collection manager within ten business days of the notice of seizure.
Installment Agreement Rejections and Terminations
Payment plan disputes run on a 30-day clock. You must appeal a rejected proposal on or before the 30th day after the rejection letter. Similarly, you have 30 days from a notice of intent to terminate, and a further 30 days after termination takes effect. However, if the rejection or termination came from a revenue officer, your appeal must be in writing, preferably on Form 9423. A manager conference is recommended but not required for these appeals.
Deadlines and the Foreign Postmark Trap
For Americans abroad, the phrase postmarked within three business days hides a serious problem. The timely-mailing rule in section 7502 of the Internal Revenue Code generally protects documents deposited in the US mail or sent through an IRS-designated private delivery service. A Royal Mail postmark from Guildford does not carry the same protection. Therefore, you should never rely on international post for a CAP deadline.
Designated Private Delivery Services
The IRS publishes a list of designated private delivery services, and several of their international express products qualify. Using one of those listed services gives you proof of timely delivery that the IRS recognises. Alternatively, where a revenue officer has provided a fax number, faxing the signed form and keeping the transmission report is the fastest option. We recommend doing both, because a three-business-day window leaves no room for a lost courier envelope.
Time Zones and Business Days
Business days mean US federal business days, and they follow US public holidays rather than UK bank holidays. Consequently, a conference held on a Friday afternoon in Washington falls on a Friday evening in London, and your three days run from the US date. In addition, Thanksgiving and Independence Day can shift a deadline that looks comfortable from Britain. We diarise every CAP deadline against the US federal calendar for exactly this reason.
Authorising a Representative
You may represent yourself, but most British-resident clients authorise a US representative on Form 2848, Power of Attorney and Declaration of Representative. A representative can take manager conferences during US hours and file within the window. Furthermore, the IRS will only discuss your account with someone holding a valid authorisation, so file Form 2848 before the first call, not after.
What Happens After You File
Once Appeals receives a timely collection appeals program request, the IRS normally stops the disputed collection action for the tax periods under review. According to Publication 1660, the exception applies where the IRS believes collection is at risk. Additionally, the Appeals officer may decide the case on the file Collection forwarded, or may ask for further information.
The Levy Hold on Installment Agreement Appeals
Payment plan appeals carry a statutory protection. Under section 6331 of the Internal Revenue Code, the IRS cannot levy for 30 days after rejecting or terminating an installment agreement. If you appeal within those 30 days, the levy bar continues until Appeals decides, unless collection is in jeopardy. The regulations at 26 CFR 301.6331-4 spell out those periods in detail.
The Collection Statute Keeps Moving
The IRS normally has ten years from assessment to collect a tax. However, the levy bar during an installment agreement appeal also suspends that ten-year clock for the same period. As a result, a successful appeal can extend the time the IRS has to collect. For clients whose balances are close to expiry, the IRS Collection Statute Expiration manual is essential reading before choosing any route.
When Appeals Decides Against You
A CAP loss is final within CAP, but it does not end every option. For example, you may still request a CDP hearing if a qualifying notice later arrives, submit an offer in compromise, or seek help from the Taxpayer Advocate Service. Nevertheless, the Taxpayer Advocate Service cannot extend any CAP, CDP or equivalent hearing deadline. Therefore, missing the first window is far more costly than losing the first argument.
What the IRS Can Reach While You Live in Britain
The practical value of the collection appeals program depends on which of your assets are genuinely exposed. The US-UK income tax treaty, published on GOV.UK's USA tax treaties page, contains no general article on mutual assistance in collection. Moreover, British courts apply the long-standing revenue rule, which refuses to enforce foreign tax claims.
US Assets Are the Real Targets
Your UK current account, ISA and London property sit largely outside direct IRS levy reach. By contrast, US brokerage accounts, US bank accounts, US rental income, US pension distributions and federal tax refunds all sit within it. For high-net-worth clients, a levy on a US investment account is the most common trigger for a CAP appeal. Consequently, the size of your US asset base often decides whether CAP is urgent or merely advisable.
Your Passport Sits in the Same Picture
Serious tax debt carries a travel consequence. The IRS may certify a seriously delinquent tax debt to the State Department, which can then deny or revoke a US passport, and the 2026 threshold is $66,000. The IRS passport certification guidance confirms that debts under an agreed installment agreement are excluded. Accordingly, winning a payment plan appeal under the collection appeals program can protect far more than a single account. Our guide to IRS passport revocation for tax debt covers certification in full.
How HMRC Compares
HMRC has no direct equivalent of the collection appeals program. Instead, a UK taxpayer who cannot pay negotiates a Time to Pay arrangement, described on the GOV.UK guidance on difficulties paying HMRC. In addition, HMRC's enforcement tools include direct recovery of debts from bank accounts under Schedule 8 to the Finance (No. 2) Act 2015, subject to safeguards. For dual filers, the two systems therefore run side by side, and a payment plan with one authority must account for commitments to the other.
A Worked Case Study: Saving a $412,000 Portfolio
The following illustrative case combines features of several matters, with details changed. It shows how the collection appeals program works under real time pressure for an American in London.
The Facts
Daniel is an American investment banker living in Richmond. After four years of missed US tax returns, he filed late in 2025 and was left with an assessed balance of $186,400, including penalties and interest. He proposed an installment agreement of $4,200 a month. Subsequently, a revenue officer rejected it, arguing that Daniel could pay $11,500 a month because his London rent and school fees exceeded IRS allowable expense standards. Daniel's US brokerage account held $412,000, largely in positions carrying $97,000 of unrealised gains.
The Pressure Point
The revenue officer warned that a levy on the brokerage account would follow. A forced sale would have crystallised the $97,000 gain, adding roughly $23,100 of US federal tax at 20% plus the 3.8% net investment income tax. Worse, UK capital gains tax at 24% would also arise, and the timing mismatch threatened his foreign tax credit position. Therefore, speed mattered more than anything else.
What We Did
We requested a conference with the Collection manager within a day of the rejection. When the manager upheld the decision, we notified the revenue officer the same afternoon and faxed a signed Form 9423 the next morning, with a courier copy sent through a designated delivery service. The submission documented Daniel's UK income tax and National Insurance, which the officer had omitted from his calculation, and priced London housing on actual, necessary costs. Additionally, we offered a $40,000 lump sum from a UK bonus due within 60 days.
The Outcome
Appeals decided within six business days. It accepted an installment agreement at $6,300 a month after the $40,000 payment, finding that the officer had failed to allow Daniel's UK tax of more than $5,000 a month. As a result, no levy issued, the brokerage account stayed intact, and the $23,100 forced-sale tax charge never arose. Moreover, the agreed plan removed the debt from passport certification. The whole collection appeals program process took eight business days from rejection to decision.
How TaxYork Can Help
TaxYork provides comprehensive US and UK tax preparation and compliance for high-net-worth Americans in Britain. We prepare the returns that resolve the underlying balance, including US tax returns for expats, and we prepare and file collection appeals program submissions within the business-day deadlines. Furthermore, our team calculates the foreign tax credit and treaty position that revenue officers routinely overlook, drawing on our US-UK tax treaty optimisation work.
In our experience, most CAP appeals are won or lost on the financial evidence prepared before the manager conference. Therefore, we assemble UK payslips, P60s, HMRC calculations and US account statements in the IRS format before the first call. We also coordinate the collection strategy with any outstanding FBAR or Form 8938 filings, so that fixing one problem does not expose another.
Conclusion
The collection appeals program is the fastest administrative tool an American in Britain has against an IRS lien, levy or rejected payment plan. It covers more actions than Collection Due Process and usually delivers a decision within days. However, it cannot reduce the tax itself, and its decision is final, with no route to court.
For British-resident clients, the real risks sit in the procedure rather than the law. A foreign postmark, a US public holiday or a missed two-day notice can end the appeal before it starts. Accordingly, treat every CAP deadline as immovable, prepare your financial evidence in advance, and fix any disputed liability through the proper route first. Handled properly, the collection appeals program protects your US assets, your passport and your long-term position.
