CRS 2.0, CARF and the 2027 EU Banking Rule: What Your Bank Reports
The short answer
CRS and CARF reporting for a digital nomad runs on one thing: the tax residence you declared when you opened the account. Your bank already reports your balances to that country. From 2026 data, crypto and e-money join the file. The EU's separate CRD VI banking rule governs licences, not tax, and does not order banks to close individuals' accounts.
Three regimes land across 2026 and 2027 and they do different things. Two are about information. One is about banking authorisation. All three sit downstream of the tax residency you declare, which is why separating them is worth the twenty minutes.
The baseline: what the CRS already reports
The Common Reporting Standard is the OECD's framework for the automatic exchange of financial account information. A bank identifies where each account holder is tax resident, reports their balance and income to that jurisdiction annually, and the jurisdictions swap files.
The identification step is a self-certification: a declaration of your country or countries of tax residence and your taxpayer identification number in each. Japan's National Tax Agency states that individuals must provide one for accounts opened on or after 1 January 2017, and that a TIN from a jurisdiction of residence other than Japan is legally required on it.
It is not a formality. HM Revenue and Customs' International Exchange of Information Manual at IEIM405118 states that an account holder who fails to provide a valid self-certification is "liable to a penalty of up to £300" where the failure is deliberate or due to a lack of reasonable care. Citibank Hong Kong's individual CRS form, like most, requires a fresh certification within 30 days of a change in circumstances.
The tax residence on that form is the most consequential line in your banking paperwork, because it decides which revenue service receives the file. It is meant to be the output of a legal test rather than a preference, and we work through those tests in how tax residency is decided.
The United States is the gap in the map
The CRS is not universal. The United States does not participate in it and runs the Foreign Account Tax Compliance Act instead. The IRS describes FATCA as generally requiring foreign financial institutions to "report on the foreign assets held by their U.S. account holders", alongside legislation "requiring U.S. persons to report, depending on the value, their foreign financial accounts and foreign assets."
The flows are asymmetric: information about Americans abroad travels inward to the IRS, while the outward leg runs through bilateral agreements rather than the CRS network. Ireland's Revenue list of crypto reportable jurisdictions, as of 10 June 2026, does not include the United States in either cohort.
CARF: what the crypto framework actually collects
The Crypto-Asset Reporting Framework is the OECD's extension of automatic exchange to crypto, published in June 2023 alongside the CRS amendments. The obligation sits on intermediaries — exchanges, brokers and certain wallet and payment providers, defined as Reporting Crypto-Asset Service Providers — not on you.
The OECD's published CARF text sets out three categories of Relevant Transaction: exchanges between relevant crypto-assets and fiat currencies, exchanges between forms of relevant crypto-assets, and transfers, including reportable retail payment transactions. A crypto-to-crypto swap is two reportable events, valued in fiat, and alongside them sits the identity layer the CRS already uses: name, address, jurisdiction of tax residence and TIN. Cashing out is not the trigger; trading inside an exchange is already inside the perimeter.
In the EU the instrument that makes CARF law is DAC8, Council Directive (EU) 2023/2226, in force from 13 November 2023, with a transposition deadline of 31 December 2025 and obligations applying from 1 January 2026. Transposition has been ragged: KPMG reports that on 30 January 2026 the European Commission sent letters of formal notice to twelve member states that had not notified national DAC8 measures, among them Spain, the Netherlands and Portugal.
When CARF starts, and how many countries are in
The intended pattern is data collection from 1 January 2026 and first exchanges in 2027 on 2026 information. Ireland's Revenue states it plainly: "Commencing in 2027, Revenue will exchange information on relevant Crypto-Asset Transactions", under CARF and Article 8ad of the amended Directive 2011/16/EU.
The counts are where published figures diverge. Revenue's list, as of 10 June 2026, names 48 jurisdictions undertaking first exchanges by 2027 and 26 by 2028 — Ireland's partners, not the global register. An OECD and Global Forum list last updated 17 June 2025 showed 52 for 2027 and 17 for 2028; 2026 commentary reports the mid-to-high forties. The list has been revised repeatedly through 2026, so check the current OECD and Global Forum register rather than any article's count, including this one.
Two laggards matter. Switzerland is the major financial centre that has slipped: its Federal Council decided on 26 November 2025 that the crypto provisions of the Swiss automatic exchange legislation would not apply in 2026, and the State Secretariat for International Finance puts implementation at 2027 at the earliest. Revenue's own list places Switzerland in the 2028 exchange cohort. The United States is in a later cohort again — the 17 June 2025 list placed it in 2028, 2026 commentary reports a 2029 target — and leans on domestic broker reporting meanwhile: the IRS instructions for Form 1099-DA require brokers to complete the form for sales of covered securities on or after 1 January 2026, having not required basis reporting for 2025 sales. That is a domestic return, not an international exchange.
CRS 2.0: e-money and CBDCs come inside the perimeter
CRS 2.0 is the amended Common Reporting Standard, and it is routinely confused with CARF. Different instruments, different jobs.
According to PwC's analysis of the OECD amendments, the CRS was amended to bring certain electronic money products and central bank digital currencies into scope, and so that indirect investments in crypto-assets through derivatives and investment vehicles are covered by the CRS rather than CARF. Carey Olsen's note, and the British Virgin Islands guidance summarised by Maples, define a specified electronic money product as a digital representation of a single fiat currency, issued on receipt of funds and redeemable at par.
Read that definition twice. It describes the multi-currency balances this audience actually lives on — the category covered in our comparison of Wise and Revolut — much of which sat outside the old CRS perimeter and is being pulled inside it.
Timing is set jurisdiction by jurisdiction. Maples reports that the Cayman Islands amendments took effect on 1 January 2026, with certain operational changes from 2027, and the Virgin Islands government has stated an intention to introduce CRS 2.0 from 1 January 2026, with collection through 2026 and submission by May 2027. Which year a provider starts reporting you changes what a tax authority sees, so this is worth a cross-border accountant's eye rather than an assumption that a year is invisible.
CRD VI Article 21c, and what it does not do
This is the one that gets misread. Article 21c of Directive (EU) 2024/1619, the sixth Capital Requirements Directive, requires third-country undertakings to establish a branch in the member state where they wish to operate, and to obtain authorisation, before providing core banking services into the EU.
According to King and Spalding's March 2026 analysis, the services in scope are taking deposits and other repayable funds, granting credit including consumer credit and lending secured on immovable property, and providing guarantees and commitments. Most CRD VI measures apply from 11 January 2026; the third-country branch requirements apply from 11 January 2027 and do not catch contracts entered into before 11 July 2026. Article 21c carries exemptions, which King and Spalding and Morrison and Foerster both read as covering interbank business, intragroup provision, services ancillary to MiFID investment business, and reverse solicitation where the client approaches the non-EU institution at its own exclusive initiative — a route Morrison and Foerster's July 2026 note warns is read narrowly. Published analyses place those carve-outs in different sub-paragraphs of Article 21c, so the paragraph numbering is worth checking against the directive text itself.
Now the scope limit. This rule is about which institutions may serve EU clients, aimed principally at cross-border lending and corporate banking. It is not a tax reporting rule and it does not instruct any bank to close an individual's account. None of the firm analyses reviewed here documents a retail closure programme attributable to Article 21c. The realistic consequence is duller: a non-EU institution unwilling to build an EU presence may narrow which EU-resident customers it takes on. Transposition is uneven too, with Morrison and Foerster reporting that member states differ on when cross-border lending counts as occurring within their territory and that European Banking Authority guidance was outstanding as of July 2026. The banking landscape itself sits in our digital nomad banking guide.
The four regimes side by side
| Regime | What it governs | Who it applies to | Reported or required | Key date |
|---|---|---|---|---|
| CRS (existing) | Exchange of financial account information | Reporting financial institutions in participating jurisdictions | Identity, tax residence, TIN, balance and income, sent to the declared residence jurisdiction | In operation; self-certification standard from 2017 |
| CRS 2.0 (amended) | Same exchange, wider perimeter | Same institutions, plus providers of specified e-money products and CBDCs | Adds e-money and CBDC accounts, and indirect crypto exposure via derivatives and funds | By jurisdiction: Cayman from 1 January 2026; BVI submission by May 2027 |
| CARF | Exchange of crypto-asset transaction information | Reporting Crypto-Asset Service Providers: exchanges, brokers, some wallet and payment providers | Identity and tax residence, plus crypto-to-fiat and crypto-to-crypto exchanges and transfers | Collection from 1 January 2026; exchanges 2027 |
| CRD VI Article 21c | Authorisation to serve EU clients | Third-country credit institutions and certain large third-country investment firms | A licensed EU branch or authorised entity for deposits, lending and guarantees. No reporting element | From 11 January 2027; contracts before 11 July 2026 fall outside |
What this means in practice for a nomad
The change is not that a new agency is watching you. It is that a declaration you made years ago is cross-checked against far more data.
- A stale tax residence on file is a growing liability. If the country on your self-certification is one you believe you left but never formally exited, it keeps receiving your file. That exit is covered in becoming a non-resident.
- Crypto at a reporting service provider is no longer effectively private. Once CARF collection runs at your exchange, the record exists whether or not you convert to fiat.
- "Resident nowhere" is the answer that gets flagged. A certification with no jurisdiction on it is an incomplete form, not a neutral one, and Citibank Hong Kong's individual CRS form notes that extra checks apply where the only residence declared sits in a jurisdiction on the OECD's list of potentially high-risk residence-by-investment schemes. We take that plan apart in whether you can have no tax residency at all.
- Closures track documentation, not CARF. The European Banking Authority's 2023 de-risking guidelines exist because institutions refuse or terminate relationships on anti-money-laundering grounds, and the EBA's position is that blanket category exits without individual risk assessment "can be unwarranted and a sign of ineffective ML/TF risk management." Finland's supervisor, Finanssivalvonta, found in a thematic review published on 29 September 2025 that incomplete customer due diligence and unclear origin of funds were among the commonest grounds for refusal — and that the problem is overwhelmingly a business-customer one: it reports that around 11 per cent of corporate account applications were refused in 2024, against 0.8 per cent for private persons.
What to actually do
None of this is fixed by moving money. It is fixed by making the declaration true.
- Keep the tax residence on your self-certification current, and expect to re-certify as providers refresh files for CRS 2.0 and CARF.
- Keep the evidence a bank asks for when it challenges a certification: a residence certificate from the tax authority, a lease, a registration document. Obtaining the first is covered in our guide to tax residency certificates.
- Keep a day log and the travel records behind it: the residence you declare has to survive someone else's arithmetic.
- Resolve the underlying residency position rather than the paperwork. If you do not know which country you are resident in, the certification cannot be fixed before the residency is, and that is where an accountant who does cross-border work earns the fee.
The bottom line
Three regimes, two jobs. The CRS, its amended version and CARF are information rules closing the gap between what you declared and what can be seen: crypto transactions, e-money balances and CBDC holdings enter the exchange network on 2026 data reported in 2027, with real variation by jurisdiction. CRD VI Article 21c is not in that family. It decides which non-EU institutions may serve EU clients from 11 January 2027, and the forum claim that it forces banks to close nomads' accounts does not survive contact with the text.
What is left is the oldest problem in this subject, now better instrumented: knowing which country is entitled to call you resident, and having said so on the form. That is worked through in full in our guide to nomad tax residency.
Frequently Asked Questions
What is the Crypto-Asset Reporting Framework (CARF)?
CARF is the OECD framework, published in June 2023, extending automatic exchange of tax information to crypto. The obligation falls on Reporting Crypto-Asset Service Providers: exchanges, brokers and some wallet and payment providers. They report user identity and tax residence alongside three categories of relevant transaction — crypto-to-fiat exchanges, crypto-to-crypto exchanges and transfers.
When does CARF start?
Data collection runs from 1 January 2026 with first exchanges in 2027 covering the 2026 year, and Ireland's Revenue confirms it will begin exchanging crypto-asset transaction information in 2027. Dates vary: the Swiss Federal Council decided on 26 November 2025 that the crypto provisions would not apply in 2026, and the United States sits in a later cohort.
What is the difference between CARF and CRS?
CARF covers crypto-asset transactions at crypto service providers. The CRS covers financial accounts at banks and similar institutions, reporting balances and income rather than transactions. PwC's analysis of the OECD amendments notes one deliberate interlock: indirect crypto exposure through derivatives and funds is handled by the amended CRS, not CARF.
Will my bank close my account because I live abroad?
Closures overwhelmingly follow failed or inconsistent self-certification and anti-money-laundering checks, not the new reporting rules. The European Banking Authority's 2023 de-risking guidelines exist because institutions terminate relationships on AML grounds, and the EBA says blanket category exits without individual risk assessment can be unwarranted. Finland's supervisor, Finanssivalvonta, found incomplete due diligence among the commonest grounds for refusal in its September 2025 thematic review, which also reports that only 0.8 per cent of private-person applications were refused in 2024.
Does CRD VI Article 21c affect my personal bank account?
Not as a reporting matter. King and Spalding's analysis describes Article 21c as requiring non-EU institutions to hold a licensed branch before providing core banking services into the EU from 11 January 2027, with contracts concluded before 11 July 2026 outside it. It is an authorisation rule aimed mainly at cross-border lending, not an instruction to close accounts.
Does the United States participate in the CRS?
No. It operates FATCA instead, which the IRS describes as generally requiring foreign financial institutions to "report on the foreign assets held by their U.S. account holders", with US persons separately reporting foreign accounts and assets by value. The consequence is asymmetry: inbound information about Americans abroad is extensive, the outbound leg far thinner.
