TL;DR: Two reporting traps catch more Americans abroad than any other tax issue: the FBAR (FinCEN Form 114) and the California exit-tax positions on departing residents. FBAR is owed once your aggregate foreign accounts top $10,000 USD at any point in the year — penalties start at $10,000 per non-willful violation and escalate to 50% of account value for willful failures. California has no formal “exit tax” yet, but its aggressive domicile rules can keep you a California taxpayer for years after you’ve moved abroad if you don’t sever ties cleanly. Both are solvable; both are unforgiving if you ignore them. Below: the practical workflow.

Part 1 — FBAR for Americans abroad
What FBAR actually is
FBAR is FinCEN Form 114, filed online via the BSA E-Filing System. It is not part of your IRS tax return — it goes to Treasury’s Financial Crimes Enforcement Network. The threshold is the aggregate maximum balance of all your foreign financial accounts at any moment during the calendar year. If at any single point your combined foreign accounts touched $10,001 USD, you owe an FBAR for that year.
What counts as a foreign account
- Foreign bank accounts (checking, savings, term deposits)
- Foreign brokerage and securities accounts
- Foreign mutual funds and pooled investment vehicles
- Foreign-based crypto exchange accounts (per 2026 FinCEN guidance — domestic-only U.S. exchanges still don’t trigger FBAR)
- Foreign pensions and retirement accounts (Canadian RRSP, Mexican AFORE, Portuguese PPR plans)
- Foreign life insurance with cash value
- Signature authority over an employer’s foreign accounts (yes — accountants and CFOs, this is you)
Filing mechanics and deadlines
FBAR is due April 15 with an automatic extension to October 15 — no form needed for the extension. Filing is free at bsaefiling.fincen.treas.gov. You report:
- Each account number, institution name, and country
- The maximum balance during the year (in USD using year-end Treasury rate or the daily rate when the maximum occurred)
- Account type and whether you have signature authority only versus financial interest
Penalties — why this is the form people lose sleep over
Non-willful: $10,000 statutory cap, inflation-adjusted to approximately $16,536 per violation per year for 2026 (per FinCEN’s January 2025 inflation adjustment). Per the 2023 Bittner v. United States Supreme Court decision, this cap applies per FBAR form, not per account — a meaningful taxpayer win. Willful: the greater of $100,000 or 50% of the account balance, per year, criminal exposure available. The IRS can go back 6 years; willful violations have no statute of limitations.
If you’re behind
The Streamlined Filing Compliance Procedures remain the standard remediation in 2026 for non-willful failures. You file 6 years of FBARs, 3 amended 1040s, and a non-willful certification. No penalties for the FBARs, but you owe the back tax plus interest. For willful conduct, the OVDP (now Voluntary Disclosure Practice) is the path — penalties are reduced from criminal-exposure levels but remain steep.
FATCA Form 8938 — the IRS’s parallel form
Form 8938 (Statement of Specified Foreign Financial Assets) is filed with your 1040, not separately. It overlaps with FBAR but isn’t identical. Thresholds for taxpayers living abroad: $200K single / $400K married filing jointly at year-end, or $300K/$600K at any point during the year. File both — they are not substitutes.
Part 2 — California exit tax (and the “domicile” trap)
The myth and the reality
California does not currently impose a formal “exit tax” on departing residents. Bills proposing one (AB 2088 and successors) have been introduced multiple times since 2020 but none has passed. That said: California’s existing residency and domicile rules are aggressive enough that thousands of expats are still taxed by California for years after physically leaving. The “trap” is not a new tax — it is the FTB (Franchise Tax Board) refusing to recognize that you’ve actually left.
How California decides if you’re still a resident
California uses two concepts: residency (physical presence) and domicile (intent to remain). The FTB applies a 19-factor test from Corbett v. Franchise Tax Board when contesting a non-residency claim. The factors that move the needle most:
- Where your physical home is (selling vs renting your CA house matters)
- Where your spouse and minor children live
- Where your driver’s license, voter registration, and vehicle registration are
- Where you bank, where your professional advisors are, where your safety-deposit box is
- Where your “permanent” mail goes
- Where you spend more than 6 months in any year
- Where your business activities and source of livelihood are based
- The location of your social, religious, and professional affiliations
No single factor is dispositive. The FTB looks at the whole picture and is documented to challenge departures aggressively for taxpayers with $1M+ income or significant equity events.
The “183-day rule” is not a safe harbor
California has no clean 183-day safe harbor like federal residency rules. Spending fewer than 183 days in California is necessary but not sufficient — if your domicile remains California, you can be a California resident even if you spent zero days there. The rule that protects “spending fewer than 183 days” applies only if you also break domicile.
The 7-step domicile-break checklist
- Sell or rent your California home on arm’s-length terms. Don’t keep it as an obvious return base.
- Move your driver’s license to your new state or country.
- Re-register vehicles in the new jurisdiction.
- Update voter registration outside California — vote where you actually live.
- Change your professional advisors (CPA, lawyer, doctors) to the new location, or at minimum to non-California.
- Move banking and brokerage to non-California addresses; sever credit-card and utility accounts that don’t follow you.
- Document everything — keep a contemporaneous log of where you slept each night for the first two years post-move.
The big-equity-event scenarios
California is most aggressive with people who:
- Have a startup acquisition, IPO, or large equity vest within 2–3 years of “moving”
- Sell a long-held appreciated business or real estate
- Move just before realizing significant deferred compensation
The FTB has a documented playbook for these cases: residency audits 18–36 months after departure, demanding bank statements, calendars, gym sign-in logs, and travel records. If you anticipate a large realization event, “leaving” in November and “selling” in January doesn’t pass smell test — California will look for a clean break of at least 12 months prior.
Other states with similar dynamics
California is the most aggressive, but Virginia, New Mexico, and South Carolina apply similar domicile-leaning tests. New York is the second-toughest state — its “permanent place of abode” rule has caught many former residents who kept a Manhattan apartment for visits.
Putting both together — the 12-month departure timeline
| Timing | FBAR / FATCA action | California exit action |
|---|---|---|
| T-12 months | Inventory U.S. bank/brokerage accounts; identify which will move abroad | Sell or list CA home; start moving advisors out of state |
| T-6 months | Open foreign accounts after you’ve actually moved (avoids creating early “foreign assets”) | Update DMV, voter registration; sever non-essential CA ties |
| T-0 (departure) | Establish residency abroad; begin tracking max account balances | File final CA part-year return (Form 540NR); document departure date |
| T+12 months | File first full-year FBAR (April 15 / October 15) | Maintain “log of nights” — prepare for potential FTB audit |
| T+24 months | Second-year FBAR; review FATCA threshold | If clean break, FTB audit risk drops materially |
Where this connects to the bigger picture
FBAR and exit-tax issues are the two reporting hot spots, but they sit inside the broader U.S. expat tax framework — Foreign Tax Credit, treaty positions, FEIE, PFIC issues, totalization.

Most readers also benefit from the best-countries overview when picking a destination.
Frequently asked questions
Do I owe FBAR if my foreign accounts never crossed $10K?
No. The threshold is aggregate maximum balance. If the combined maximum of all your foreign accounts at any single moment never exceeded $10,001 USD, you don’t owe an FBAR for that year. But check carefully — a one-day spike during a transfer counts.
Does my foreign pension count for FBAR?
Yes if you have access to balance information and a level of control. Canadian RRSP, UK SIPP, Mexican AFORE, and Portuguese PPR plans are all reportable. Employer-controlled pensions where you only see a benefit statement are a gray area — most practitioners report them.
Will my foreign bank report me to the IRS automatically?
Yes, under FATCA. Almost every developed-country bank reports U.S. account holders to the U.S. Treasury annually. The IRS has your foreign account data whether you file FBAR or not. Streamlined remediation is much cheaper than waiting for a notice.
Can California really tax me after I move to Mexico or Portugal?
Yes, if your domicile remains California. The fact that you physically left does not by itself break California residency. The 7-step checklist above is the practical break.
How long does the FTB take to challenge a departure?
Typical residency audits start 18–36 months after the year you claimed non-residency on a part-year return. Expect to provide bank records, calendars, and travel logs going back 3–4 years.
Do I need a cross-border CPA?
For your first year as an expat, yes. Plan on $1,500–4,000 for a full federal + state + foreign return package. After year one, many expats DIY with software (ExpatFile, MyExpatTaxes) once the structure is set.
Bottom line
The FBAR is mostly a paperwork problem — file it on time and the form is genuinely free and fast. The penalties exist to catch people who deliberately hide money offshore; if you’re a normal expat with normal accounts, the form is a 30-minute task once a year. The California “exit” problem (informally called an exit tax, though no formal exit tax exists — see Part 2) is harder because California can challenge the residency exit itself — solve it by treating residency as something you actually break, not just leave for a while.
For both, the best lever is timing: do FBAR and CA-residency planning before you move, not after a notice arrives.
