Definition

A late account report filed with a reasonable-cause statement where the income was reported and no examination is under way.

What turns on it

Catch-up terms describe routes that are open only while a disclosure is still voluntary. Eligibility is assessed before anything is filed, because an ordinary late filing can close a route that was available the day before.

Where the two systems can differ

Two tax systems can agree on every fact of a case and still reach different answers, because each is applying its own definition to the same events. The work is not deciding which definition is better; it is establishing which one governs each question, and then filing consistently with both.

Where it turns up

The quickest way to understand Delinquent FBAR is to see it in place. These are the pages where it decides something.

What it means for your own file

The question worth asking is not what Delinquent FBAR means but whether it applies to you this year. That is a computation on your facts. Send us the facts and we will tell you what has to be filed and what it costs.

If there is a single lesson from files that went wrong on a term like this, it is that the concept was understood and the evidence was not assembled. The definition is the easy half.

Cross-border situations we are engaged for

Case study 1

Late account reports filed where income was already returned

A client had reported foreign interest on every return for years but had never filed the account reports. The engagement tested each of the three conditions the route assumes — income reported, no examination under way, and a cause that could be evidenced — then filed the outstanding reports with a statement setting out the sequence in dates. The work produced the filed reports, a reasonable-cause statement consistent with the returns, and a schedule tying each reported figure to the account it came from.

Case study 2

Aggregate test rebuilt from statements across every account

A client believed they fell under the reporting line because no single account was substantial. The test is the aggregate value of all foreign financial accounts at any point in the calendar year, so we rebuilt the yearly peaks from statements rather than closing balances, including accounts closed part-way through a year and a transfer that counted in both the sending and the receiving account. The exercise produced a year-by-year aggregate schedule and a documented conclusion about which years were reportable.

Case study 3

Returns checked before a late report route was relied on

A prospective client's position rested on the income having been reported. Checking the returns account by account showed that one account's income had been omitted for several years, which took the file outside this route as it stands. We said so in writing and set out what the alternatives involved, rather than filing reports on a premise that was not true. The engagement produced a written eligibility finding and an ordered list of the documents the next step would need.

Case study 4

Reasonable-cause statement built from correspondence rather than recollection

A client's explanation for the missing reports rested on advice received long ago. We worked from what survived — emails, an engagement letter, a bank welcome pack with a date on it — and wrote the statement around the evidenced points, marking plainly where memory was the only source. The engagement produced a statement whose every date can be traced to a document, and a file note listing the gaps so that nobody later mistakes an unevidenced recollection for a proven fact.

Case study 5

Closed accounts brought back into a set of late reports

Accounts closed years earlier had dropped out of the client's own list because the statements had gone with them. Reportability follows the year in which the account existed, so the closure did not remove the obligation for the years before it. We obtained what the banks still held, reconstructed the missing periods, and documented the basis of the estimate where nothing survived. The engagement produced complete reports for each year involved and a written record of how the figures for the unrecoverable periods were arrived at.

Case study 6

Report filings kept separate from the return position deliberately

A client wanted everything corrected in one letter. Because the account reports go to FinCEN and the returns do not, combining them produces a package that is awkward for either recipient to act on and easy to misread. We filed the reports through their own channel with the statement they require, and dealt with the return position separately and in its own terms. The engagement produced two clean filings rather than one composite one, and a note of what was sent where and when.

Case study 7

Accounts Reported Late When the Income Already Was

Where the income was on the return and only the account report was missed, a narrow route allows late filing with a reason attached. It is open only while no income is unreported and no examination has begun, which is why it is checked first.

A Secondment Whose Paperwork Decided the Tax

Who employs, who directs and who bears the cost are the facts a treaty article turns on, and an assignment letter is where they are recorded. Drafting it with the tax position in view prevents an argument later.

Core International & Cross-Border Tax Services

International Tax Planning & Advisory

Strategy and compliance for income, assets and families spread across borders.

One coordinating team: filings on every side of the border are sequenced so treaty relief and foreign tax credits are claimed once — and in the right country.

U.S. & Cross-Border Tax Returns

Dual filers: U.S. citizens in Canada and Canadians with U.S. income run two parallel systems — we prepare both, in the right order, every year.

Expat & Emigration Tax

The move year is its own project: the elections and valuations filed that year decide the next decade of both countries’ returns.

Non-Resident Canadian Tax

Default withholding is 25% of gross: elective returns routinely turn over-withheld rent and pensions into refunds.

Transfer Pricing & BEPS

Documentation prepared with the return is the cheapest insurance in international tax; reconstructing it during an audit is the most expensive.

Cross-Border Estates & Trusts

Wills drafted for one country routinely misfire in the other — deemed disposition here, estate tax there, credits in between.

Cross-Border Corporate Tax

Expansion raises the same four questions every time — entity, PE, repatriation, payroll. We answer them before the tax authorities do.

India Tax for NRIs & Returning Residents

The deduction is taken on the sale price, not the gain — which is why an NRI property sale strands cash unless the certificate is applied for before closing.

Canadian Tax with a Foreign Element

Residency is decided on facts, not on a form — and the year you arrive or leave is the one where the largest amounts turn on the smallest details.

UAE Tax for Expats & Their Home Country

A zero-tax country is only half the answer — the question that decides the bill is whether the country you came from still treats you as resident.

Athletes, Artists & Entertainers

Performance income is taxed where earned — Regulation 105 in Canada, withholding agreements in the U.S. — with special treaty articles overriding the usual rules.

Performance income is taxed where the performance happens, and the deduction is usually taken at source on the gross fee before expenses. Recovering the difference is a filing exercise in the other country, and it only works if the tour, the residency and the withholding certificates were documented while the work was being done.

The follow-up questions on Delinquent FBAR

Can I just file a late FBAR without entering a programme?

Sometimes, and the conditions are narrow. The route contemplates a late account report filed with a reasonable-cause statement, where the income from the accounts was reported on your returns and no examination is under way. If any one of those three is untrue — income left off, an enquiry already open, or no reasonable cause you can actually evidence — you are not in this route and should not file as though you were. Establishing which of the three applies is the first piece of work, and it is done from documents rather than recollection.

What counts as reasonable cause for a late account report?

A statement of what happened, in dates, that explains the failure without contradicting anything in your filings. It is not a form of words. What carries weight is the specific sequence: when the account was opened and why, what you understood at the time, who told you what, when you learned otherwise, and what you did next. Generic assertions about being unaware do little on their own. Where reliance on an adviser is part of the account, it is described as it happened, with whatever correspondence survives, and the gaps are acknowledged rather than smoothed over.

Where does the FBAR actually get filed?

It goes to FinCEN. It is not attached to your tax return and it does not travel with it, which is precisely why the two get out of step: someone who has filed returns faithfully every year can still have never filed an account report at all. Treating them as one exercise is the common mistake, because the filing that turns out to be missing is the one nobody was tracking. It is worth checking the report history separately, year by year, rather than assuming the return history answers for both.

My accounts are small — do I still have to report them?

The test is not whether any single account is large. It is the aggregate value of all your foreign financial accounts, measured at any point during the calendar year rather than on the last day of it. That has two consequences people miss: a set of modest accounts can cross the line together, and a balance that was high for one week counts even if the account was nearly empty in December. Money moved between two of your own accounts can be counted in both. List every account first, then test the aggregate.

I reported the interest but never filed the reports — is that better?

It is materially better, because the route for a late report assumes the income was on the returns. It is also the position that allows the smallest fix: the missing filings are the reports themselves, with a statement explaining why they were late, rather than a reopening of the returns. Establish it properly, though. Reported means the income appears in the right place for each year, which is worth checking account by account before anything is filed, because a single omitted account changes which route you are in.

What if the IRS has already asked me about a foreign account?

Then this route is likely closed, and the first task is reading what has arrived rather than filing. The position depends on no examination being under way, so a notice can be the event that ends it. Bring the correspondence in date order, together with anything a bank has sent you about your tax residence or your accounts. What the letter asks for usually decides what is still available, and filing into a route that has already closed makes the position worse rather than better.

Do I pay US tax on an inheritance from abroad?

A bequest is not income, so the receipt itself is not taxed. Reporting is a different matter: a US person who receives large gifts or bequests from a foreign person or estate files an information return for the year, and inheriting a foreign account or an interest in a foreign trust brings the account and asset reports with it. The penalties here attach to the information return, not to tax — which is why people who owed nothing still get letters. See Form 3520.

Do American citizens living abroad have to pay taxes?

American expats and green card holders need to file US returns for life, and many of them pay little or no US tax once the relief is applied — but the filing is what unlocks the relief, so the two questions have different answers. The exclusion for foreign earned income, the credit for foreign tax already paid and the treaty between the two countries between them usually leave the total at roughly the higher of the two countries' tax rather than the sum. Skip the return and none of it applies. See Americans abroad.
