Crypto Tax and Residence: What Reporting Changes in 2027

Crypto tax has become a question of residence rather than disclosure. From 2026, exchanges and service providers collect data on their users. From September 2027, tax authorities swap it automatically. Where you are resident decides which administration receives your file, and which rules apply to your gains.

Crypto Tax and Tax Residence: What the New Global Reporting Changes

Key takeaways

• Data collection started on 1 January 2026 across the European Union under DAC8.

• First automatic exchange takes place by 30 September 2027, covering 2026 data.

• 76 jurisdictions have committed, in three waves running from 2027 to 2029.

• Residence decides everything: the country you live in receives the report and taxes the gain.

What is actually changing in crypto tax reporting?

Two instruments, one design. The OECD built the Crypto-Asset Reporting Framework, and the European Union wrote it into law as DAC8.

DAC8 entered into force on 1 January 2026. From that date, crypto-asset service providers operating in the EU collect identification and transaction data on their users. Reports go to national tax authorities in 2027, and cross-border information is exchanged within nine months of the reporting year.

30 September 2027 is the date the first exchange completes, covering the 2026 calendar year. The data being gathered right now will land on a tax administration's desk long before most holders think about it.

The framework mirrors what already exists for bank accounts under the Common Reporting Standard. Crypto simply lost its exemption.

One design choice matters for holders. Reporting follows the user's declared country of residence rather than the platform's location, so moving an account to a different exchange changes nothing about where the data lands.

Which jurisdictions exchange, and when?

Seventy-six have committed, but they do not start together. The gaps between waves matter for anyone who has moved recently or plans to.

The staggering has a practical consequence. Someone who moved from Germany to Dubai in 2026 sits in a country reporting from 2028, while their former country reports from 2027. The two systems reach full coverage at different moments, not at the same one.

The United States stands alone in the 2029 wave, two years behind the European Union. That is notable because the country never joined the Common Reporting Standard for bank accounts. Its participation in CARF marks a change of position rather than a routine extension.

The list of jurisdictions that have not committed is now very short. The OECD identifies five relevant ones: Argentina, El Salvador, Georgia, India and Viet Nam. Two of those are already working towards a commitment. The map of places outside the framework has almost closed.

Professional Insight from Hexagone Group

An independent global advisory firm, Hexagone Group works with high-net-worth individuals and families holding assets across several jurisdictions. Its Hexagone Group private wealth advisers recommend documenting acquisition dates and costs for every holding now, while records remain retrievable. They also caution that a change of residence rarely takes effect on the day of the flight, since most countries apply their own residence tests to the whole tax year.

Why does tax residence now decide the outcome?

Because the report follows the holder, not the platform. Service providers identify each user's country of residence and route the information there.

That makes residence the single variable that determines three things at once: which authority sees your holdings, which country taxes a disposal, and which holding-period rules apply to it. The same portfolio produces very different outcomes in different jurisdictions.

The rules themselves diverge sharply. Some countries treat crypto disposals as capital gains, others as ordinary income, and a few exempt gains after a minimum holding period. None of that changes because of CARF. What changes is that the authority now knows the position, and can check the return against it.

The consequence for internationally mobile holders is simple. Residence planning and crypto tax are no longer separate questions.

What information is reported?

More than most holders expect, and the scope is deliberately broad.

• Identification data: name, address, tax residence and taxpayer identification number.

• Transaction totals: aggregate gross amounts for acquisitions and disposals against fiat and against other crypto-assets.

• Transfers: aggregate fair market value where assets move rather than trade.

• Asset coverage: crypto-assets under the MiCA definitions, stablecoins, e-money tokens and certain non-fungible tokens.

• Decentralised issuance: assets issued without a central issuer fall within scope.

Note what is not reported. The framework captures gross flows, not net gains. The tax authority receives the totals and expects the holder to reconcile them with a declared position, which is where discrepancies surface.

That distinction produces a predictable problem. An investor who moved 400,000 euros between three exchanges over a year generates reported gross amounts far larger than any actual gain. Without a documented cost basis, explaining the difference falls entirely on the holder, years after the transactions took place.

What should a holder check before changing residence?

Five points, and the sequence matters more than the individual answers.

• Confirm the exchange wave of both your current and intended country of residence.

• Reconstruct your cost basis across every platform, including those you no longer use.

• Check the residence test in the destination country, which is rarely a simple date of arrival.

• Identify any exit charge on unrealised gains in the country you are leaving.

• Review holding-period rules, since a disposal timed weeks apart can fall under two different regimes.

Treating the move itself as the planning event is where holders lose ground. The reporting obligations attach to a full calendar year, and a mid-year relocation splits that year between two administrations.

Professional Insight from Hexagone Group

As an independent wealth advisory firm working with private clients across jurisdictions, Hexagone Group guides investors on how digital assets fit within a wider estate and residence plan. Its consultants recommend addressing succession alongside reporting, since crypto held in self-custody can be reported to a tax authority while remaining entirely inaccessible to heirs. They advise documenting access arrangements with the same discipline applied to any other asset class.

What happens when crypto passes to the next generation?

Reporting solves visibility for tax authorities. It solves nothing for families.

A holding reported under CARF still requires private keys, seed phrases or exchange credentials to be transferred. An estate can be fully declared and completely unrecoverable at the same time. That gap between fiscal transparency and practical access is specific to this asset class.

Succession rules add a second layer. Where the holder was resident at death usually determines which inheritance regime applies, and crypto is rarely addressed explicitly in national estate law. Families holding significant digital assets across borders face a question their advisers may not have been asked before.

The reporting era does not make crypto simpler. It makes the underlying residence and succession questions impossible to postpone.
