Streamlined filing: three returns, six FBARs, and one test that decides the penalty

Three and six, not three and three

The two numbers that define the programme are different from each other, and almost every summary of it flattens them into one. It is 3 years of returns and 6 years of FBARs.

They differ because they are two obligations under two statutes filed with two agencies. The return goes to the Internal Revenue Service. The FBAR goes to the Financial Crimes Enforcement Network, on its own deadline, with its own back period. Somebody who files 3 years of returns and 3 years of FBARs has not completed the procedure, and has spent the effort anyway.

The years are counted from the most recent for which the due date has passed, which is not the same as the most recent calendar years. In the months between a filing deadline and the next one, the window does not move.

What the procedure says about the two periods

"for each of the most recent 6 years for which the FBAR due date has passed, file any delinquent FBARs (FinCEN Form 114, previously Form TD F 90-22.1)."

The 330-day test, and what it is worth

There are two streamlined procedures, and the only thing separating them is where you live. The foreign version carries no miscellaneous offshore penalty. The domestic version carries 5% of the highest aggregate balance or value of the foreign financial assets concerned, measured across the whole covered period.

The test has two limbs and both must hold in at least one of the 3 covered years: no United States abode, and physically outside the United States for at least 330 full days. It is one of the years, not all of them, which is more generous than it first reads.

Abode is not the same as residence and not the same as domicile. Somebody who kept a home in the United States available to them can fail on the first limb while satisfying the second comfortably, and that is the failure mode worth checking before assuming the penalty does not apply.

What the procedure says about non-residency

"the individual did not have a U.S. abode and the individual was physically outside the United States for at least 330 full days."

What 5% of the highest balance actually comes to

The domestic penalty is not 5% of unpaid tax and not 5% of the closing balance. It is 5% of the highest aggregate value the assets reached at any point in the covered period, which for an account that peaked and was then spent down is measured at the peak.

• Every figure in the middle column is arithmetic on the rate in the rule, not a quoted amount. The rate is the sourced fact; the products are shown so the size of the difference is legible.
• Tax and interest are owed on both paths. It is the penalty that differs, and on a large balance the difference is the whole cost of the exercise.

Non-willful is a certification, not an adjective

Both procedures require a signed statement, under penalty of perjury, that the failure to report was non-willful. That statement is the programme. It is not a box to tick alongside the forms; it is the thing being examined, and it asks for the specific facts of your own case rather than a characterisation of them.

A taxpayer whose conduct was not non-willful is not eligible, and using the procedure anyway is a worse position than not using it. This page states what the thresholds and the periods are. It does not and cannot tell you whether your facts meet that standard, and any page that offers to is selling something.

What the procedure does not fix

• Accounts below the FBAR threshold of $10,000 were never reportable, so there is nothing to catch up on. Check whether you had an obligation before entering a programme designed to cure one.
• A return already under examination is outside the programme. The procedures are for taxpayers the Service has not yet come to.
• Tax and interest on the 3 years are owed in full on both paths. The relief is from penalties, not from the liability.
• Years outside the 3 and 6 year windows are not brought into compliance by filing inside them, and the programme does not represent that they are.

Why the two procedures are so often described as one

They share a name, a certification and a set of forms, and they differ in the one respect that decides what the exercise costs. A page that describes "the streamlined procedure" and quotes a single penalty is describing whichever one its author had in mind, and the reader has no way to tell which.

This site holds them as separate rules under separate identifiers, cited to separate pages of the Service's own instructions, which is why both figures appear above with their own quotes rather than one appearing as the figure.

How to check a figure you found somewhere else

The reason this subject is unreliable online is not that writers are careless. It is that the figures change annually, they are published in documents nobody reads for pleasure, and a page that was right when it was written stays online long after it stops being right. A page with no date on the figure is not making a claim you can check.

Three questions settle almost every case. First, which tax year does this apply to, and is that the year the income was earned or the year the return is filed? Second, what document set it, and does the page name the section rather than the website? Third, when was it read, and does the page say?

Applied to the streamlined procedures, those three questions are answerable from this page: every figure names its tax year, its source document and section, and the date it was read, and the sentence it came from is archived with a hash so a change at source shows up rather than being absorbed silently.

That standard is not a courtesy. A calculator or a guide that quietly serves last year's figure produces an answer no reader can distinguish from the right one, which is worse than an obvious error and far harder to notice.

Where this sits alongside the calculators

Reporting obligations and tax liability are different questions and they are answered by different parts of this site. This page is about the streamlined procedures: a threshold or an amount set by a document, which either applies to you or does not.

The calculators answer the other question. They take a gross salary in one of the jurisdictions this site models and compute what is actually deducted from it, band by band, with each rate carrying the rule behind it. Every one of those jurisdictions has been checked against the average tax rates the OECD publishes for a single person at three different incomes, and any jurisdiction that missed by more than half a percentage point is not published at all.

Somebody working abroad usually needs both. The domestic calculation tells you what the country you live in takes. Pages like this one tell you what your home country still wants to know about. Neither substitutes for the other, and a page that blurs them is the reason so many people abroad discover a reporting obligation years late.

What this site does not do

It does not give advice, and it does not model your situation. Everything here assumes a single person on employment income with no dependants and no reliefs beyond those stated, because that is the only shape that can be computed identically across jurisdictions and compared honestly.

It does not model treaty relief, foreign tax credits, remittance rules, self-employment, or the interaction between two countries taxing the same income. Those are real and they change answers, and each of them requires facts about you that a page cannot know.

What it does do is state the underlying figures accurately, with their sources, and compute the domestic position in each jurisdiction it covers. That is the input every adviser asks for first, and it is the part most often wrong on the pages that rank above this one.
