What Is CARF? The Crypto Reporting Rules, in Plain English

CARF is the OECD's Crypto-Asset Reporting Framework: a global system where crypto exchanges and brokers report your identity, balances, and transactions to tax authorities, which then share that data with the country where you're tax resident. It went live in roughly 50 jurisdictions on January 1, 2026. Self-custody wallets carry no reporting duty of their own.

Every relocation plan eventually hits the same question.

You find the zero-tax jurisdiction, you price the visa, you map the flights… and then someone asks: “doesn’t your exchange report all of this now anyway?”

Since January 1, 2026, the answer is mostly yes. That’s CARF.

The bank-account playbook, applied to crypto

For a decade, banks worldwide have run something called the Common Reporting Standard (CRS): your bank tells its tax authority who you are and what you hold, and that authority automatically forwards the file to the country where you’re tax resident.

CARF, the Crypto-Asset Reporting Framework, is the OECD running that exact playbook on crypto.

The OECD finalized the rules in 2023, and 48 jurisdictions committed in a joint statement that November. As of late 2025, the commitment list had grown to 76.

No new tax was created. CARF is purely an information pipe… but information pipes are how taxes get enforced.

What actually gets reported, and to whom

The reporting duty falls on what the framework calls Reporting Crypto-Asset Service Providers, or RCASPs (read: exchanges, brokers, dealers, and some custodial wallet services).

If you have an account at one, they collect and report:

  • Who you are: name, address, date of birth, tax identification number, and country of tax residence
  • What you did: crypto-to-fiat trades, crypto-to-crypto swaps, and transfers, with gross proceeds and aggregate values, reported annually
  • Where you sent it: withdrawals to addresses the exchange can’t identify as another service provider (your hardware wallet, for instance) get reported as aggregate transfer values

Even large retail payments get caught: pay a merchant more than $50,000 in crypto through a provider and that transaction is flagged under the framework’s rules.

The flow is the part that matters. Your exchange reports to its tax authority, which then automatically exchanges the file with the tax authority of your residence country.

The file goes to the country where you live, no matter where the exchange sits.

The timeline, jurisdiction by jurisdiction

Data collection started January 1, 2026 across roughly 50 jurisdictions (sources count 48 live on day one, with the committed list at 76 and most exchanges of data starting by 2027).

Some markers worth knowing, drawn from the jurisdictions in this directory:

  • The EU implemented CARF through a directive called DAC8. Collection from January 1, 2026; first filings due by September 30, 2027. That covers Switzerland’s neighbors and every EU member on our list… and Switzerland itself is phasing in CARF from 2026 on its own track.
  • Cayman Islands: live January 1, 2026. Zero tax, full reporting.
  • Singapore: slated for 2027.
  • UAE: signed in 2025, reporting by 2028.
  • Paraguay: not a signatory as of mid-2026. One of the few holdouts left.
  • The United States isn’t in CARF at all. It built a parallel system instead: brokers report gross proceeds on Form 1099-DA starting with 2025 transactions, and cost basis from 2026. Some reporting suggests the US may join CARF around 2029, but I wouldn’t plan around that date either way.

So the gaps exist. They’re just shrinking on a published schedule.

What CARF killed

The fantasy it ended was specific: keep living where you live, open an account on an exchange in some friendly jurisdiction, and let distance do the hiding.

That’s dead. The exchange asks where you’re tax resident, and the report follows the answer (the same way it has for bank accounts since CRS started in 2017).

An account in Dubai held by a tax resident of Germany generates a file that lands in Germany. The exchange’s location stopped mattering; your location is the whole game.

Which means the only version of the relocation play that still works is the real one: actually moving, actually becoming tax resident somewhere else, actually building a life there. Our guide to crypto-tax-free countries covers which jurisdictions make that worth doing.

What CARF didn’t touch

This is where the doom takes get it wrong.

CARF regulates intermediaries, not the protocol. A person holding bitcoin in their own wallet, with their own keys, has no reporting obligation under the framework, because there’s no service provider in the picture to do the reporting.

Same for genuine peer-to-peer transactions. Two people, one transfer, no platform in the middle: nothing for CARF to capture.

The honest caveat: the on-ramps and off-ramps are thoroughly captured. The withdrawal that moved coins from your exchange to your hardware wallet was reported in aggregate. The eventual sale back to dollars will be reported too. And the blockchain itself is public, which is a separate visibility problem CARF didn’t create and doesn’t control.

So neither extreme survives contact with the text of the framework. “Privacy is dead” ignores that self-custody sits entirely outside the reporting net. “They can’t touch you” ignores that nearly every ramp between crypto and the banking system now files a report.

I’ll be honest about one more thing: how aggressively tax authorities will act on this flood of data, and how fast, is genuinely unclear. The pipe exists. What flows through it in practice… we’ll find out over the next few years, fellow builders, same as everyone else.

The two takeaways

First: jurisdiction still matters, but only the real kind. Picking where you’re tax resident is still one of the highest-leverage decisions available. What’s gone is the pretend version. The report follows your actual residency, so the question becomes “where do I actually want to live?” rather than “where can I hide an account?”

Second: self-custody matters more than it did in 2025. Notice what CARF could and couldn’t reach. The rules reached every intermediary, because intermediaries are companies that follow laws. The rules couldn’t reach keys you hold yourself, because there’s nobody standing between you and the asset to compel.

That’s the sovereignty ladder distinction in action. An exchange account is a paper guarantee: it works as long as institutions keep their promises, and those promises just got rewritten globally in about three years. Keys in your own wallet are bedrock: math that holds whether or not anyone is watching.

CARF rewrote the paper layer for 50-plus countries at once. It left the bedrock layer exactly where it was.

When a framework this thorough reaches every intermediary on earth and stops cold at the keys in your hand, it has told you something useful about which layer to build on.

(Usual caveat, plainly: I’m a guy who reads frameworks, not your tax advisor. Rules differ by country and change fast… talk to a professional who knows your situation before acting on any of this.)

From the atlas

United Arab Emirates

The UAE levies 0% personal income and capital gains tax on crypto for individuals across all emirates, with no personal tax filing at all. A 10-year golden visa costs about AED 2M (~$545K) in property. The catches: business activity falls under 9% corporate tax, CARF reporting starts by 2028, and citizenship is effectively unavailable.

Trusted third party

Singapore

Singapore has no capital gains tax, so personally held crypto sells tax-free — a rule firmly in place heading through 2026. The catch: IRAS can reclassify frequent, high-volume activity as trading income taxed at up to 24%, and residency is the hard part — employment passes or a S$10M investor program. CARF reporting is slated for 2027.

Trusted third party

Switzerland

Private investors pay no capital gains tax on crypto in Switzerland, but holdings face an annual cantonal wealth tax of roughly 0.1–1%, and staking or mining income is taxed. Frequent leveraged trading risks professional-trader classification, which makes gains taxable. Stable and rule-of-law, with CARF reporting phasing in from 2026 — and a high cost of living.

Trusted third party

Cayman Islands

The Cayman Islands levies no income, capital gains, or wealth tax at all — crypto disposals are simply untaxed, with nothing to structure around. A 25-year residency certificate requires about $1.2M invested, including $600K in developed real estate, plus ~$146K annual income. The catches: CARF reporting went live January 1, 2026, living costs are among the world's highest, and citizenship is a decades-long prospect.

Frequently asked questions

Can the IRS see my crypto wallet?
Not directly. A self-custody wallet reports nothing to anyone. What the IRS sees is what brokers report on Form 1099-DA (gross proceeds from 2025, cost basis from 2026), plus whatever blockchain analysis firms piece together from the public ledger. The moment your coins touch a US exchange, that activity is visible.
Does CARF apply to cold wallets?
The cold wallet itself, no. Holding your own keys creates no reporting duty under CARF. But the withdrawal that funded it does: when you move coins from an exchange to an address the exchange can't identify as another service provider, the exchange reports the aggregate value of those transfers. They know the coins left. They don't see what happens after.
Which countries are not in CARF?
The list shrinks every year. As of mid-2026, Paraguay has not signed, and the United States runs its own parallel system (Form 1099-DA) instead of joining the exchange network, with some reports suggesting it may join around 2029. About 76 jurisdictions have committed overall, so treating any gap as permanent is a bet against a clear trend.
When does CARF start in the UAE and Singapore?
Singapore's CARF reporting is slated for 2027, and the UAE committed in 2025 to start by 2028. Both currently charge zero capital gains tax on personally held crypto, so for a genuine tax resident there, the report that eventually gets filed shows gains that aren't taxed anyway.
Does moving to a no-tax country stop CARF reporting?
No, and that's the point of the system. Your exchange reports to the tax authority of whatever country you're tax resident in, based on the residence documentation you gave them. If you genuinely live in a zero-tax jurisdiction, the report still gets made; it just lands somewhere with no tax to collect. Paper residency without real relocation doesn't change where the data flows.
Is peer-to-peer crypto trading reported under CARF?
A genuine peer-to-peer trade, two people, one transaction, no intermediary, has no service provider in the middle and so nothing gets reported. But most platforms that call themselves P2P do act as intermediaries, and those can qualify as reporting providers under CARF. The framework captures the ramps where crypto meets the banking system, not the protocol itself.
What exactly does my exchange report under CARF?
Your name, address, date of birth, tax identification number, and country of tax residence, plus annual transaction data: crypto-to-fiat trades, crypto-to-crypto swaps, gross proceeds, and transfers, including aggregate values for withdrawals to wallets the exchange can't identify. Large retail payments in crypto above $50,000 are also flagged under the framework's rules.
