Cross-Border Wealth & Offshore Banking
Holding money abroad is legal. Hiding it is not. These 2026 guides explain the reporting rules that actually apply in the USA, UK, Australia, Canada, Italy and Portugal — FBAR and FATCA, CRS 2.0, Quadro RW, Anexo J and Form T1135 — plus the new crypto reporting framework that started this January.
Editorial note: this series covers legal compliance and disclosure only. We do not publish tax-avoidance techniques, secrecy strategies or “loopholes”, and we recommend only regulated money-transfer providers.
FATCA, FBAR & Foreign Accounts (2026)
FBAR's USD 10,000 aggregate rule, Form 8938 thresholds, penalties, and the streamlined route back into compliance if you are behind.
CRS, Worldwide Income & HMRC Disclosure (2026)
What HMRC already receives through CRS, the post-non-dom regime, nudge letters and the Worldwide Disclosure Facility.
Overseas Accounts & ATO Reporting (2026)
Worldwide income rules, AUSTRAC transfer reporting, crypto data matching and how voluntary disclosure cuts penalties.
Form T1135 & Foreign Property (2026)
The CAD 100,000 cost-amount test, the first-year exemption for new residents, deemed acquisition values and the CRA disclosure programme.
Quadro RW, IVAFE & Foreign Assets (2026)
Italy's foreign-asset monitoring return, the wealth taxes attached to it, DAC8 crypto reporting and ravvedimento operoso.
Anexo J, IBAN Reporting & CRS (2026)
Declaring foreign income and account identifiers, what NHR/IFICI does and does not exempt, blacklisted jurisdictions and voluntary regularisation.
Cross-Border Wealth & Offshore Banking · In-depth
What this hub covers — and the line it never crosses
Almost everyone who moves country ends up with money in two places. A savings account left behind, a flat you have not sold, a pension paid in the old currency, a brokerage account you opened years before you emigrated, or crypto sitting on an exchange registered somewhere else entirely. Holding those assets is completely legal in all six countries we cover. The obligation that comes with them is disclosure, and that is what this hub is about.
We write this series deliberately narrowly. You will not find schemes, secrecy jurisdictions or ways to keep an account out of sight, because that content is both unlawful in effect and dangerous for readers. What you will find is the reporting architecture each country actually runs — FBAR and FATCA Form 8938 in the United States, the Common Reporting Standard for the UK, Australia, Italy, Portugal and Canada, Quadro RW and IVAFE in Italy, Anexo J in Portugal, and Form T1135 in Canada — explained in the order you need it, with the official source for every rule so you can verify it yourself.
The framing matters because the risk is asymmetric. Declaring an account you did not strictly need to declare costs you nothing. Failing to declare one you did can cost a percentage of the balance, extend the tax authority's assessment window by years, and in the worst cases become criminal. Offshore is not a loophole; it is a reporting category.
Who these guides are written for
New arrivals who kept an account at home, returning nationals, dual citizens, remote workers paid across borders, retirees drawing a foreign pension, and anyone who inherited assets in another country. In other words, ordinary migrants — not high-net-worth structures.
What we do not cover
Trust and company structuring, residency-by-investment tax planning, and anything that depends on a jurisdiction not sharing data. We are not tax advisers and these pages are not advice for a specific situation.
The 2026 change that affects every country: CRS 2.0 and crypto
The OECD's amended Common Reporting Standard, together with the Crypto-Asset Reporting Framework (CARF), extends automatic exchange of financial account information to crypto-asset service providers, some e-money and digital wallet products, and a wider set of investment entities. Data collection under CARF began in January 2026, with the first international exchanges following in 2027. Inside the EU the same expansion arrives through DAC8, which is why the Italian and Portuguese guides describe it in local terms.
For readers, the practical translation is simple. A crypto exchange account held abroad is now treated much like a foreign bank account. If you have been reporting your bank interest but leaving crypto disposals off the return on the assumption that nobody could see them, that assumption expires this year. Every country guide in this hub flags the change and shows where the crypto figures belong on the local return.
How to move money between countries without creating problems
Use regulated providers and keep the paperwork. Wise, OFX, Revolut, Remitly and ordinary bank wires are all licensed, all reported, and all leave the clean audit trail you actually want when a bank asks where a large deposit came from. Compare the exchange-rate margin rather than the visible fee — the margin is usually where the real cost sits.
Two habits prevent nearly all friction. First, keep a one-line note and a supporting document for the source of every significant transfer: a sale contract, a payslip, a probate letter, a gift declaration. Second, never split a payment into smaller amounts to stay under a reporting threshold. Automatic reporting of large transfers is routine and harmless; deliberately structuring around it is a separate offence in every country on this list, regardless of whether the underlying money is clean.
If you are already behind on reporting
Every country here runs a formal correction route — Streamlined Filing Compliance Procedures in the US, the Worldwide Disclosure Facility in the UK, ATO voluntary disclosure in Australia, ravvedimento operoso in Italy, voluntary regularisation in Portugal, and the CRA's Voluntary Disclosures Program in Canada. In all six, coming forward before the authority contacts you is the single biggest factor in reducing what you pay.
Frequently asked questions
Is offshore banking legal?
Yes, in all six countries we cover. Holding a foreign bank, brokerage or crypto account is lawful. What is unlawful is failing to report the account where reporting is required, or omitting the income and gains it produces from your tax return.
Does my tax authority already know about my foreign account?
Probably. Over 100 jurisdictions exchange account data annually under the Common Reporting Standard, and the United States runs the equivalent through FATCA. From 2026, CARF and DAC8 extend that exchange to crypto-asset service providers.
Which form applies to me?
FBAR and Form 8938 for US persons, self-assessment foreign pages for UK residents, the foreign income labels for Australian residents, Quadro RW for Italian residents, Anexo J for Portuguese residents, and Form T1135 for Canadian residents above the CAD 100,000 cost-amount threshold. Each country guide sets out the thresholds and deadlines.
What if my foreign account earns nothing?
Several regimes are balance-based rather than income-based. A dormant, zero-interest account still counts toward the US FBAR aggregate, still needs to appear in Italy's Quadro RW, and still counts toward Canada's T1135 test. Declare it anyway — declaring is free.
Do you recommend any specific offshore bank or scheme?
No. We recommend regulated transfer providers for moving money and we explain reporting obligations. We do not recommend jurisdictions, structures or products, and we do not publish anything designed to reduce tax through non-disclosure.
