The Streamlined Domestic 5% Penalty: Exactly Which Accounts and Which Year-End Balances It Is Computed On

The miscellaneous offshore penalty is misunderstood in both directions — taxpayers imagine 5% of the whole portfolio and pay too much, or assume 5% of the tax and are shocked at the worksheet. The rule, from the domestic track's own instructions: the penalty equals 5% of the highest aggregate balance or value of the taxpayer's foreign financial assets that are subject to the penalty, during the years in the covered tax return period and the covered FBAR period. Three components each need precision. First, which assets are "subject to the penalty": a foreign financial asset enters the base for a year if it should have been reported on an FBAR for that year and wasn't, or should have been reported on Form 8938 for that year and wasn't, or generated income that was not reported on that year's return — so a properly FBAR'd account whose income was reported stays out; an account reported on the FBAR but whose interest was omitted comes in; and an account never reported anywhere comes in for every year it existed within the window. Second, which years: the base is measured across the covered period — the three tax years for the returns and the six years for FBARs — using each year's year-end value (December 31 balance, or the value at year-end for non-account assets), and the penalty applies to the single highest aggregate among those year-ends, not to each year separately and not to peak intra-year balances (the FBAR reports maximum values; the streamlined penalty uses year-end values — a common conflation that overstates the number). Third, aggregation: within each year, add the year-end values of all assets subject to the penalty for that year; the penalty is 5% of the largest such annual sum. Practical texture that moves the figure: currency conversion runs at the year-end rate for each year (the Treasury year-end rates are the standard reference), so a CAD account's USD value swings with the exchange rate independent of the account itself; an account closed mid-window has a zero year-end value for years after closure but full values before — the closure date matters; assets held through entities (the Canadian corporation's accounts) enter the analysis through the owner's reporting obligations for them; registered plans count if they were reportable and unreported — an RRSP omitted from the FBAR is in the base even though its income was treaty-deferred, because the FBAR reporting failure alone qualifies it; and joint accounts enter at full value for each spouse's FBAR obligation but are counted once in a joint submission. The base also has an important exclusion: assets that were properly reported and whose income was reported are not penalized just because they sit next to ones that weren't — the taxpayer who reported the brokerage account but forgot the small savings account pays 5% of the savings account's highest year-end value, not the brokerage's. The payment mechanics: the penalty is computed on the Form 14654 worksheet, listed by asset and year, and paid with the submission alongside the tax and interest for the three amended years; no interest accrues on the penalty itself if paid with the submission. Where the number comes out badly, the decision returns to the track question — is any covered year a foreign-track year? — and to the alternative routes: where every dollar of income was in fact reported and only the information returns were missed, the delinquent FBAR and delinquent information return procedures carry no penalty at all, and the domestic track's 5% is a price paid only by those whose income also went unreported.

Key takeaways

• The base is assets, not tax: 5% of the highest aggregate year-end value across the covered years of the foreign financial assets that were unreported on the FBAR, unreported on Form 8938, or whose income went unreported on the return.
• Year-end, not peak: the penalty uses December 31 values; FBARs report maximum values — don't compute the penalty on the FBAR figures.
• One year, the highest: aggregate the qualifying assets within each covered year, then take the single largest annual total; the penalty is not charged year by year.
• Properly reported assets stay out: the base is the failure, not the portfolio — an account that was FBAR'd with its income reported is excluded even if it's the largest one you hold.
• Registered plans can be in: an RRSP left off the FBAR qualifies through the reporting failure alone, treaty deferral notwithstanding; closed accounts count for the years they existed; currency converts at each year-end rate.
• The number feeds the route decision: a large base sends you back to the residency test for a foreign-track year, and to the penalty-free delinquent procedures if — and only if — all income was actually reported.

Building the worksheet

Columns: each foreign financial asset; rows: each year in the covered period. For each cell, the year-end value in USD at that year's rate, entered only if the asset was subject to the penalty that year (unreported on FBAR or 8938, or income unreported) — otherwise blank. Sum each year's column; the penalty is 5% of the largest sum. Attach the account statements that support each year-end figure and the conversion source. The worksheet is the exhibit the submission is judged on, and the taxpayer who builds it accurately often finds the number is a fraction of the "5% of everything" figure they feared.

Worked example

A Canadian who moved to Chicago six years ago, filed 1040s every year, and never reported three Canadian accounts: an RRSP (C$220,000, income treaty-deferred but never FBAR'd), a TFSA (C$60,000, income never reported), and a chequing account (C$8,000, negligible interest, never FBAR'd). She closed the TFSA two years ago. Base analysis: all three were unreported on FBARs for every year they existed in the six-year window, so all three enter for those years; the TFSA drops to zero for the years after closure. Year-end aggregates in USD at each year's rate range from about US$205,000 (the most recent year: RRSP plus chequing, TFSA closed, weaker CAD) to about US$229,000 (three years back: all three accounts, stronger CAD). Penalty: 5% of US$229,000 — US$11,450. The two numbers she'd been told before the worksheet: "5% of your Canadian assets" (US$400,000-plus including her Canadian home, which is not a financial asset — wrong), and "5% per year" (five times the real figure — wrong). Her track check confirms no foreign-track year (six years in Chicago), and her income-reporting check confirms the TFSA's income was unreported, closing the penalty-free delinquent route. US$11,450, paid with three amended returns and Form 14654, ends nine years of exposure — and the worksheet, not the folklore, produced the number.

Official sources

The Title 26 miscellaneous offshore penalty is "5 percent of the highest aggregate balance/value of the taxpayer's foreign financial assets that are subject to the miscellaneous offshore penalty during the years in the covered tax return period and the covered FBAR period," and that highest aggregate is "determined by aggregating the year-end account balances and year-end asset values" of each covered year and taking the highest. — Internal Revenue Service, U.S. Taxpayers Residing in the United States, https://www.irs.gov/individuals/international-taxpayers/us-taxpayers-residing-in-the-united-states

A U.S. person must file an FBAR "if the aggregate value of those foreign financial accounts exceeded $10,000 at any time during the calendar year reported"; it is filed electronically through FinCEN's BSA E-Filing System, and "you're allowed an automatic extension to October 15 if you fail to meet the FBAR annual due date of April 15." — Internal Revenue Service, Report of Foreign Bank and Financial Accounts (FBAR), https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar

Practitioner note

The 5% is the most mis-estimated figure in cross-border catch-up: clients arrive quoting 5% of everything, or 5% per year, and leave with a worksheet showing a fraction of either. We compute it asset by asset and year by year at year-end rates, exclude what was properly reported, and then use the result to pressure-test the route — because a large base is the signal to hunt for a foreign-track year or, where income was fully reported, to use the penalty-free delinquent procedures instead.
