Form 14654 is the IRS certification titled Certification by U.S. Person Residing in the United States for Streamlined Domestic Offshore Procedures, currently Rev. 9-2017, Catalog Number 67044W. Signed under penalties of perjury, it certifies the failure to report foreign income and accounts was non-willful, schedules the assets subject to the Title 26 miscellaneous offshore penalty year by year, and computes that penalty at 5% of the highest aggregate of year-end values.

Is the 5% penalty based on the highest balance during the year or the year-end balance?

Year-end values only. The IRS aggregates year-end account balances and asset values for each year in the covered tax return period and covered FBAR period, takes the highest annual aggregate and multiplies it by 5%. A large balance passing through an account mid-year and gone by 31 December never appears on Form 14654. Guidance describing the base as the highest balance at any point in the six years is wrong.

Do I have to name the accountant I relied on?

Yes, if you are claiming reliance. Form 14654 requires the adviser's name, address and telephone number together with a summary of the advice. There is no option to claim reliance anonymously. If you are not prepared to name the adviser, the narrative should not rest on reliance and should explain the failure on its own facts instead.

Are my UK ISAs included in the Form 14654 penalty base?

Very likely, if they were unreported. GOV.UK confirms ISAs are a tax-free savings wrapper, but that is UK treatment only. For US purposes an ISA is a foreign financial account, the income and gains inside it fall within the US tax net, and an account that should have been reported on an FBAR or Form 8938 and was not meets the IRS inclusion test. Its year-end value goes on the asset schedule in US dollars.

What if my spouse will not sign the joint certification?

The IRS streamlined FAQs for US-resident taxpayers permit a joint amended return to be submitted with one signature where it shows a net increase in tax. Write SDO FAQ 14 in red ink on the non-signing spouse's signature line and attach an explanation of why the signature could not be obtained. This is not available where the return shows a net decrease in tax or an increase in credits.

Can I fix a mistake in a Form 14654 after filing?

Yes, provided the returns are not already under examination. The IRS streamlined FAQs allow corrected amended returns and, or, an amended Form 14654 with amended written in red ink on it, plus an explanation of the facts and circumstances, mailed to the same Austin streamlined unit, with corrected FBARs e-filed if required. Once an examination opens, that route closes.

Form 14654: Certifying a Streamlined Domestic Filing

Form 14654 is the sworn certification a US person living in the United States signs to enter the IRS Streamlined Domestic Offshore Procedures, and it is the single document on which the whole submission stands or falls. It does three jobs at once: it declares under penalties of perjury that the failure to report foreign income and foreign accounts was non-willful, it schedules year by year the foreign financial assets sitting in the penalty base, and it computes the 5% Title 26 miscellaneous offshore penalty the taxpayer consents to have assessed. The IRS is blunt about the consequence of getting it wrong: a submission that does not follow the instructions is processed in the normal course without the benefit of the favourable terms. You pay the money and buy nothing.

What follows is about the certification itself rather than the programme around it. For a US citizen or green card holder living in the United States with UK accounts, UK investments or shares in a UK company, this is where the file is won or lost.

What is Form 14654 and what does it actually certify?

Form 14654 is the IRS form titled Certification by U.S. Person Residing in the United States for Streamlined Domestic Offshore Procedures. The version in circulation is Rev. 9-2017, Catalog Number 67044W, carrying OMB Number 1545-2241. The IRS estimates the average time to complete the streamlined certification at eight hours, which is worth quoting to anyone who assumes it is a signature exercise stapled to three amended returns. On the face of the form, the signatory certifies each of the following.

That amended returns, with all required information returns, are provided for each of the most recent three years for which the return due date, or extended due date, has passed.
That original returns were previously filed for those same years.
The tax owed each year as shown on Form 1040-X, the interest and the totals, in a table headed Year, Amount of Tax I Owe Shown On Form 1040X, Interest, Total.
That income from one or more foreign financial assets went unreported.
That all eligibility requirements for the Streamlined Domestic Offshore Procedures are met.
That any FBARs for the last six years that were not timely, correct and complete are now electronically filed.
That the listed assets are the taxpayer's only foreign financial assets subject to the 5% penalty.
That the penalty computation shown is accurate.
That the failure to report all income, pay all tax and submit all required information returns was due to non-willful conduct.

The IRS definition of non-willful conduct is reproduced on the form and is narrower than most people assume: conduct due to negligence, inadvertence, or mistake, or conduct resulting from a good faith misunderstanding of the requirements of the law. Note what is absent. There is no allowance for conduct that was deliberate but well intentioned, nor for a taxpayer who suspected an obligation and chose not to investigate. The certification is a factual claim, not a plea in mitigation.

Who signs Form 14654 rather than Form 14653?

The dividing line between the two streamlined certifications is the non-residency requirement. A taxpayer who meets it certifies on Form 14653 under the foreign procedures and faces no miscellaneous offshore penalty. A taxpayer who fails it certifies on Form 14654 and accepts the 5% penalty. For a joint submission, only one spouse needs to fail the non-residency requirement for the couple to fall into the domestic procedures, which catches many transatlantic couples where one spouse relocated earlier. Beyond that, there are hard eligibility gates a certification cannot paper over.

Original returns must already have been filed for each covered year. The IRS states expressly that delinquent income tax returns, including Form 1040, may not be filed using these procedures. A non-filer is not an SDOP candidate.
A valid Taxpayer Identification Number is required. Under the IRS streamlined FAQs, a submission processed under an internally assigned IRSN rather than a valid SSN or ITIN is not eligible for the favourable penalty provisions.
The taxpayer must not be under IRS civil examination for any year, nor under criminal investigation by IRS Criminal Investigation.
The failure must genuinely be non-willful on the IRS definition, and the narrative must demonstrate that rather than assert it.

One wrinkle: where the most recent covered year is already fully compliant, the IRS streamlined FAQs direct that Form 14654 still be attached to a Form 1040-X for that year showing zero change in tax. The certification needs a return to travel with.

What must the Form 14654 narrative statement of facts contain?

The narrative is neither optional nor decorative. The form carries its own instruction in terms that leave no room: any submission that does not contain a narrative statement of facts will be considered incomplete and will not qualify for the streamlined penalty relief. It can go in the expanding field on the form or be supplied as a signed attachment. The form then specifies what it must cover.

Specific reasons for the failure to report all income, pay all tax and submit all required information returns, including FBARs. Generic statements about not knowing the rules do not qualify.
The whole story, including favourable and unfavourable facts. The form uses that phrasing deliberately.
Personal background and financial background, plus anything else relevant to the failure.
The source of funds in every foreign account and asset. Examples on the form include an account opened while residing abroad and one opened for a business reason.
Contacts with each account or asset, including withdrawals, deposits and investment or management decisions.
Where a professional adviser was relied on, the adviser's name, address and telephone number, and a summary of the advice given.
Where married taxpayers certify jointly with different reasons, the individual reasons for each spouse stated separately.

The adviser disclosure catches people off guard. Clients regularly want to say they relied on their accountant without naming the accountant, and the form does not permit that halfway position. Either reliance forms part of the narrative, with the name, address, telephone number and substance of the advice, or reliance is not claimed. An unnamed adviser is an unverifiable assertion, and that is what a reviewer discounts.

How do you write a non-willful narrative that survives review?

The reviewer is testing coherence: they hold three amended returns, six FBARs, the asset schedules and a story, and are asking whether the story explains the documents. Narratives fail not because they are short but because they are unfalsifiable. Build outwards from the documents, not inwards from the explanation.

Set a chronology with month and year detail: arrival in the United States, when each account was opened, when balances moved, when the reporting obligations were first understood.
Handle each account separately with its own source of funds. UK employment income earned before relocation, proceeds of a UK property sale, a legacy account at a UK bank and a founder shareholding are four different stories and should read as four.
Describe actual contacts with the account. Dormant and actively managed accounts point in opposite directions on willfulness, and the form asks the question directly, so silence is conspicuous.
Identify the discovery event and what followed: a FATCA notice from a UK bank, a Common Reporting Standard letter, a new adviser's question. Then show the gap between discovery and remediation was short.
Own the unfavourable facts in your own words. If the Schedule B foreign account question was answered incorrectly, or a prior adviser was told about an account and did nothing, say so. A reviewer who finds an omitted fact stops reading for explanation and starts reading for evasion.
Reconcile the narrative to the numbers. If the story says an account was dormant while the schedule shows the year-end balance doubling, the story is wrong.

A word on tone. The perjury declaration covers the certification and all accompanying schedules and statements. Emotive language, argument about the fairness of US extraterritorial taxation and complaints about complexity weaken a document meant to read as a factual record.

How is the 5% miscellaneous offshore penalty computed on Form 14654?

The Title 26 miscellaneous offshore penalty is 5% of the highest aggregate balance or value of the foreign financial assets subject to the penalty during the years in the covered tax return period and the covered FBAR period. The mechanics matter more than the rate, and this is where competing guidance is most often wrong. The IRS aggregates year-end account balances and asset values for each year separately, then takes the highest of those annual aggregates. It is not the highest balance touched at any point in the six years, and it is not the sum of the years. Each covered year gets its own table on the form, with columns for the name, city and country of the institution or a description of the asset, the account number, the year the account was opened or the asset acquired, and the year-end value in US dollars.

Which assets go into those tables is a separate question from which accounts existed. The IRS identifies three inclusion tests.

An asset that should have been, but was not, reported on an FBAR in a given year of the six-year covered FBAR period.
An asset that should have been, but was not, reported on a Form 8938 in a given year of the three-year covered tax return period.
An asset properly reported for a year in the covered tax return period, but in respect of which gross income was not reported that year.

What stays out matters just as much. Under the IRS streamlined FAQs for US-resident taxpayers, assets in which the taxpayer had no personal financial interest, such as an employer account over which only signature authority was held, are excluded, and income-producing foreign real estate not reportable on an FBAR or Form 8938 is not included. Where a foreign corporation is involved it is the stock, not the corporation's own accounts, that enters the base, unless the entity is disregarded, in which case the underlying accounts come in instead. That stock may be valued by any reasonable method, such as the Form 5471 balance sheet, and no valuation discounts are permitted. One trap: assets reported on delinquent rather than timely information returns remain in the base.

Three mechanical features are routinely missed. The form provides a seventh year table, used only where the three-year covered tax return period does not completely overlap the six-year covered FBAR period. Where no assets were subject to the penalty in a year, the instruction is to enter N/A next to Total rather than leave it blank. And a continuation sheet, needed where more than four assets are held in a year, must itself be signed with the taxpayer names and TINs printed on it.

A worked example: computing the Form 14654 penalty (illustrative)

The following figures are constructed to illustrate the mechanics and are not drawn from any client file. Assume a US citizen who has lived in New York throughout, holding a UK current account, a UK stocks and shares investment account and a minority shareholding in a UK trading company. Original Forms 1040 were filed every year, but the UK interest, dividends and fund income were omitted and no FBARs or Forms 8938 filed. Aggregating year-end values of the three penalty-base assets across the six covered FBAR years gives these annual totals.

Year 1: $1,180,000
Year 2: $1,340,000
Year 3: $1,610,000
Year 4: $1,455,000
Year 5: $1,720,000
Year 6: $1,690,000

The highest aggregate is Year 5 at $1,720,000, so the miscellaneous offshore penalty is 5% of that, or $86,000. Note that Year 3 saw the largest intra-year balance, because a UK property sale settled in March and was reinvested by November, but that peak appears nowhere on Form 14654, which asks only for year-end values. Assume the three amended Forms 1040-X show additional tax of $41,200 in aggregate. The payment block would then show $41,200 plus statutory interest to the payment date, a penalty of $86,000, and a single total payment remitted by one cheque carrying the taxpayer identification number.

What are you giving up when you sign Form 14654?

Almost no published guide reads the consent language on the form, which is a serious omission because it carries lasting legal effect. In consideration of the IRS agreeing not to assert other penalties, the signatory agrees to a defined set of concessions.

Consent to the immediate assessment and collection of the Title 26 miscellaneous offshore penalty, assessed for the most recent of the three tax years being amended.
Waiver of all defences against, and restrictions on, assessment and collection of that penalty, expressly including any defence based on expiration of the limitations period.
Waiver of the right to seek a refund or abatement of the miscellaneous offshore penalty. Once paid, it is not recoverable by the ordinary refund route.
An undertaking to retain all records, including account statements, relating to assets subject to the 5% penalty for six years from the date of the certification, and records relating to income and assets for the amended-return period for three years, and to produce them on request.
An acknowledgment that the amended returns may report income for years beyond the three-year assessment period under I.R.C. section 6501(a), that other periods in section 6501 may permit assessment, and that seeking a refund on the basis that payment was made beyond the limitations period forfeits the favourable terms.
An acknowledgment that evidence of willfulness, fraud or criminal conduct may lead to examination or investigation, civil fraud penalties, FBAR penalties, information return penalties, or referral to Criminal Investigation.

What is bought in return is precisely defined. A taxpayer who is eligible and complies with all the instructions is subject only to the Title 26 miscellaneous offshore penalty, and not to accuracy-related penalties, information return penalties or FBAR penalties. That protection survives audit: even where a properly filed streamlined return is later examined, those penalties do not apply unless the examination determines the original return was fraudulent or the FBAR violation willful. For a substantial portfolio that is a real bargain, but it is a bargain, and the retention undertakings should be diarised at filing.

How do joint filers and signatures work on Form 14654?

Joint certifications carry a specific note on the face of the form: where the certification is joint, the statements are considered made on behalf of both spouses even though the pronoun I is used throughout. That is a drafting trap. A single first-person account written by the financially engaged spouse is, by the form's own construction, asserted by the other spouse too. Where the spouses genuinely have different reasons, the form requires those reasons stated separately.

Both spouses sign a joint certification, each with printed name and date.
There is a Paid Preparer block, but the form states expressly that the taxpayer signature is required even where the form is signed by a paid preparer.
There is a yes or no box permitting another person to discuss the form with the IRS, with a designee name and number.
Where a joint amended return shows a net increase in tax and one spouse will not sign, the IRS streamlined FAQs permit submission with one signature, with SDO FAQ 14 written in red ink on the non-signing spouse's signature line and an explanation of why the signature could not be obtained. This is not available where the return shows a net decrease in tax or an increase in credits.

How does Form 14654 fit into the rest of the submission?

The certification travels with a defined package, and the assembly rules are part of what complying with the instructions means.

A complete and accurate Form 1040-X for each of the most recent three years for which the due date has passed, with all required information returns, for example Forms 5471, 5472, 8938, 926 and 8621.
Streamlined Domestic Offshore written in red at the top of the first page of each amended return and each information return.
One original signed Form 14654, with copies attached to each return and information return.
Payment of tax, statutory interest and the miscellaneous offshore penalty, with the taxpayer identification number on the cheque.
Paper filing only; the IRS states electronic submissions will not be accepted. The package goes to Internal Revenue Service, 3651 South I-H 35, Stop 6063 AUSC, Attn: Streamlined Domestic Offshore, Austin, TX 78741.
Six years of delinquent FBARs, filed separately through the FinCEN BSA E-Filing System, selecting Other as the reason for filing late and entering Streamlined Filing Compliance Procedures in the explanation box. FBARs are never mailed with the returns.

The thresholds that decide whether an asset should have been reported, and so whether it belongs in the penalty base, are the FBAR threshold of foreign accounts exceeding $10,000 in aggregate at any time in the year, and the Form 8938 thresholds for taxpayers living in the United States: more than $50,000 on the last day of the year or $75,000 at any point when unmarried or filing separately, rising to $100,000 and $150,000 for a couple filing jointly.

How do UK financial assets change the Form 14654 penalty base?

This is where a transatlantic file diverges from a generic one. UK holdings populate the asset tables in a distinctive pattern, and each category behaves differently.

Cash and current accounts at UK banks and building societies are the straightforward case: FBAR-reportable, ordinarily Form 8938-reportable and interest-bearing, so they meet the inclusion tests on more than one ground.
Individual Savings Accounts sit awkwardly. GOV.UK confirms you can save tax-free with ISAs across the four types, but that is UK treatment only. A US person remains subject to US tax on income and gains arising inside the wrapper, and the account is a foreign financial account for US reporting. An unreported ISA is a strong penalty-base candidate.
UK investment accounts holding UK-domiciled funds bring Form 8621 into the package, and the account value goes on the Form 14654 schedule. Information return obligations and the penalty base are separate questions.
A shareholding in a UK company is stock of a foreign corporation. Under the IRS streamlined FAQs it is the stock, not the company's own bank accounts, that enters the base, valued by any reasonable method such as the Form 5471 balance sheet, with no valuation discounts. Founders and shareholders in UK trading companies often find this single line dominates the computation.
UK employer share plan and nominee accounts get overlooked because the taxpayer thinks of them as employment benefits rather than accounts. Test them against the FBAR and Form 8938 rules, not intuition.
UK pension arrangements require care. Whatever position is taken on the taxation of growth inside the arrangement, the reporting analysis is separate, and an arrangement that was reportable but unreported is a penalty-base candidate. Work it through on the scheme documents.

Then there is the currency point, which changes the answer rather than the presentation. Form 14654 asks for year-end values in US dollars, and for FBAR purposes the IRS comparison of Form 8938 and FBAR requirements directs conversion using the end of the calendar year exchange rate. A sterling portfolio that never moves in sterling terms still produces six different dollar aggregates, because each 31 December is converted at that year's rate. For a UK-heavy portfolio the penalty peak is therefore often set by sterling strength on a single date rather than by any investment decision. Where two years sit close together the conversion must be consistent across every asset, because a few percentage points at the top of the table is thousands of dollars of penalty. Preparers who use an average annual rate, or different sources for different accounts, produce a number the IRS can pull apart.

Can a Form 14654 be corrected after it has been filed?

Yes, within limits, and this is the second area published guidance ignores. Under the IRS streamlined FAQs for US-resident taxpayers, a taxpayer who becomes aware of a mistake may submit corrected amended returns and, or, an amended Form 14654 with the word amended written in red ink on the form, explaining all the facts and circumstances, mailed to the same Austin streamlined unit, with corrected FBARs e-filed if needed. The critical condition is that the returns must not already be under examination. Once an examination opens, the corrective route closes and the conversation becomes an examination conversation.

Discovering an omitted account after filing is a correction problem rather than a disaster, provided it is dealt with promptly and before examination. The amended certification should explain how it was missed as well as what it was.
An arithmetic error in the penalty computation is corrected the same way. The form's own payment note warns that a balance due notice or a refund follows if the tax, interest or penalty is calculated incorrectly.
There is a narrow precedent for revisiting an already-assessed penalty: Form 14708, the Streamlined Domestic Penalty Reconsideration Request Related to Canadian Retirement Plans. Its existence shows the assessed figure is not always immovable, but it is a remedy for one asset class, not a general reconsideration route.
For procedural questions that are not case-specific, the IRS operates a streamlined hotline on 267-466-0020, which the IRS states will not provide case-specific or legal advice.

The lesson is sequencing. Because the correction window closes when an examination opens, and because the certification waives limitations defences on the penalty, a complete first submission is worth far more than the weeks it takes to reconcile every account before filing.

What are the most common Form 14654 defects?

No narrative statement of facts, or one asserting a good faith misunderstanding without describing the facts that produced it.
A narrative that omits unfavourable facts the documents disclose, which is the fastest way to move a file from processing to scrutiny.
Claiming adviser reliance without the adviser's name, address and telephone number and a summary of the advice.
Computing the penalty on the highest intra-year balance, the current balance, or the sum of the years, rather than the highest aggregate of year-end values.
Leaving penalty-base assets off the schedule, when the certification states the listed assets are the only ones subject to the 5% penalty.
Missing the red ink annotation, mailing FBARs with the paper package instead of e-filing them, or sending the package to an ordinary service centre rather than the Austin streamlined unit.
An unsigned continuation sheet, a preparer signature without the taxpayer's, or a payment that does not reconcile to the payment block on the form.
Attempting SDOP where no original return was filed for a covered year, or where there is no valid SSN or ITIN.

What happens after you file Form 14654?

Very little that is visible, for a while. The IRS states that streamlined returns are processed like any other return, that receipt will not be acknowledged, and that the process does not culminate in a closing agreement. There is no acceptance letter to wait for, and returns may still be selected for audit under existing audit selection processes, subject to the penalty protection above. What typically arrives is transactional correspondence: notices reflecting the changes to each amended year, and separate assessment of the miscellaneous offshore penalty for the most recent of the three years, consistent with the consent given on the form. The IRS publishes no service standard here and we would not invent one; the honest answer is months rather than weeks, and silence is the normal condition rather than a warning sign.

Because there is no acceptance letter, the file is the record. Keep the signed certification, the narrative, the schedules, the exchange rate source used for each year-end conversion and the statements behind every figure in the asset tables, in line with the six-year and three-year retention undertakings. If the submission is revisited, the ability to reproduce each number from primary documents is what turns a certification into a defensible position.

We prepare Streamlined Domestic Offshore submissions end to end for US persons with UK financial exposure: the covered years, the amended Forms 1040-X and information returns, the delinquent FBARs, the Form 14654 asset schedules built from primary statements, the statement of facts, and the package for the Austin unit.
