Portugal DAC8: Crypto-Asset Reporting for Expats and What DAC9 Changes

Portugal’s crypto-asset reporting rules matter even if you opened your account abroad or bought your assets before moving. The immediate task is to understand what your provider will report, check the information identifying you and preserve records that explain your transactions. Reporting gives tax authorities information; it does not, by itself, establish your tax bill.

What Portugal enacted on 3 June 2026: Law 26/2026

Portugal published Law 26/2026 on 3 June 2026. The Portuguese Tax and Customs Authority’s official notice identifies it as transposing Directives (EU) 2023/2226 and 2025/872, commonly called DAC8 and DAC9. It amends several laws, including the Personal Income Tax Code and the Global Minimum Tax Regime.

For residents organising their finances after a move, the useful starting point is a complete picture of accounts, income and tax residence. Our Portugal salary and tax hub provides wider context for that planning. Keep your employment budget and investment records connected, but assess each under its applicable rules: a new reporting requirement is not a reason to assume your monthly take-home salary has automatically changed.

DAC8 and DAC9: two different reporting frameworks

DAC8 extends automatic tax-information exchange to crypto-assets. Reporting providers collect relevant information and send it to tax authorities, which exchange information with the relevant EU countries of tax residence. The European Commission’s DAC8 explanation describes the framework and its connection to the OECD’s Crypto-Asset Reporting Framework, or CARF.

DAC9 concerns a different subject: exchanging top-up-tax information under the global minimum-tax framework for corporate groups within scope. The DAC9 directive addresses information associated with the GloBE Information Return. It is not a new personal crypto tax. Holding tokens, accepting a job with a multinational or becoming an expatriate does not, on those facts alone, make you responsible for a corporate minimum-tax return.

The practical distinction is the subject of the information. For an individual crypto investor, questions usually concern provider records and personal tax treatment. For someone responsible for an affected corporate group’s compliance, DAC9 raises a separate reporting project. Ask an adviser to identify which framework applies before accepting a broad statement that “DAC9 changes expat crypto taxation”.

Crypto-asset reporting: providers, users and tax residence

Reporting providers include businesses carrying out relevant crypto exchange transactions for users. Coverage can include crypto-to-money exchanges, crypto-to-crypto exchanges and transfers. Users may need to supply identifying details and tax-residence self-certifications, including tax identification numbers. Relevant provisions appear in Annex VI, Sections II–IV, of the consolidated EU administrative-cooperation directive.

Scope has boundaries. The reportable-crypto definition excludes central-bank digital currencies, qualifying electronic money and assets properly determined to lack payment or investment uses. These are legal classifications, not labels users can choose. Certain entities are also excluded persons. An exclusion from this crypto-reporting channel does not establish an exclusion from every financial-information regime or from tax.

For an international resident, avoid treating nationality, a residence permit, a mailing address and tax residence as interchangeable. Prepare a dated account of your circumstances and seek advice where two countries may claim residence. If a provider’s form allows multiple tax residences, do not remove one simply because you prefer another country to receive the information. Equally, an old address should not remain unchallenged after a move.

What international residents should check with their providers

Start by identifying the legal entity serving your account. A familiar trading brand may operate through different companies, and its website language does not tell you where it reports. Ask which entity holds your relationship, which tax authority receives its reporting and how you can correct inaccurate information. Keep the response alongside your account terms rather than relying on a general marketing page.

Next, review your name, address, tax identification numbers and residence declarations. Under Annex VI, Section III, the EU framework requires self-certification at the start of a relationship and, for pre-existing individual users, by 1 January 2027. Changed circumstances can require renewed verification. The transition for existing users is not a general postponement of the first reporting year.

Before exporting records, check what the files contain. Useful questions include whether downloads distinguish purchases, disposals, swaps, rewards, fees and transfers, and whether timestamps use local time or UTC. Ask how missing acquisition history is displayed. A provider receiving assets from another wallet may not have the evidence needed to explain their original purchase.

• Confirm the account’s legal entity and reporting jurisdiction.
• Review residence declarations and retain confirmation of corrections.
• Download detailed transaction files and annual statements.
• Ask how revised statements and reporting corrections are handled.
• Use the provider’s authenticated support channel for sensitive documents.

Reporting obligations versus personal income-tax liability

A provider’s information report and your Portuguese personal income-tax return, known as IRS, answer different questions. Do not treat a reported transaction value as a calculation of taxable profit, or assume that provider reporting completes your personal filing. Equally, the absence of a statement should not be used as your test for whether an item needs tax review.

For a practical assessment, organise the facts behind each category of activity. Was the asset purchased, received as compensation, earned through a service or moved between wallets? What evidence supports the acquisition date and cost? Which country’s rules require consideration? These questions help an adviser assess the applicable treatment without starting from an unexplained annual total.

When comparing a Portuguese job offer with your current position, keep guaranteed pay separate from investment proceeds. Build the household budget around a properly assessed employment package, then review crypto activity separately. Neither a promise that “Portugal exempts crypto” nor a claim that “DAC8 taxes every transfer” provides enough information for a relocation decision.

Timeline: enactment, application, reporting and information exchange

Publication, legal application, provider submission and international exchange are separate milestones. Article 15 of Law 26/2026 gives the law effects from 1 January 2026, subject to specified provisions taking effect in 2028 or 2030. Those later provisions do not generally postpone crypto reporting. See the official law, Article 15 and the reporting provisions.

Portugal’s provider deadline is 31 May following the reporting year; the first year is 2026. Authority exchanges follow a nine-month year-end deadline. The provisions are Annex III, Article 2, and amended Decree-Law 61/2013, Article 20(9)–(10). Article 124-A(3) of the IRS Code supplies the domestic resident-reporting deadline.

DAC9 has its own timetable. Amended Article 20(11)–(13) provides a normal three-month exchange window, a six-month first-year window and no first exchange before 1 December 2026. These corporate information-exchange dates are not personal IRS filing deadlines.

Cross-border financial information: avoid assuming every foreign income stream is newly reportable

A foreign pension, overseas bank account, rental property and crypto exchange account should not be treated as one reporting category. The EU already has administrative-cooperation arrangements covering several kinds of income and financial information. The European Commission’s overview of the administrative-cooperation directive explains the wider system. DAC8’s arrival does not mean every foreign income stream became newly reportable for the first time.

For each overseas interest, separate three enquiries: what the institution reports, what authorities exchange and what you personally must declare. Ask for the applicable rule rather than accepting a blanket answer about “foreign income”. An institution’s reporting jurisdiction and an income source’s country can be different pieces of the same financial picture.

A simple account inventory helps. Give each account or asset an owner, country, provider and purpose, then attach the supporting statements. Include closed accounts where they contain relevant history. This makes an adviser’s review more efficient and reduces the risk that a change in reporting terminology causes you to overlook an existing personal obligation.

Practical record-keeping checklist and illustrative relocation scenario

Keep records that explain events, rather than preserving only current balances. A balance screenshot cannot show whether assets arrived through a purchase, a reward or a transfer from another account. Save original exports before combining them in a spreadsheet, and document corrections so another person can follow your reasoning.

Consider an illustrative relocation: Maya moves from the Netherlands to Portugal during 2026, starts a salaried role and retains an exchange account opened before the move. She transfers assets from a wallet she controls into that account and later sells part of them. This example assumes no particular tax-residence outcome, exemption or tax rate.

Compare two ways of preparing her records. In the first, Maya keeps only the exchange’s incoming-transfer value and sale receipt. An adviser then has to reconstruct where the assets came from. In the second, she also keeps the original purchase confirmations, wallet transaction identifiers and evidence connecting both wallets to her. The second file supports a much clearer distinction between moving assets and selling them, without predetermining the tax result.

For her relocation budget, Maya treats her salary as one workstream and the proposed sale as another. Before relying on sale proceeds for a housing deposit, she requests a review of residence, transaction history and any filing requirements. The useful outcome is an evidence-based spending decision, rather than a tax estimate derived from the fact that information will be reported.

• Keep a dated relocation chronology and supporting residence documents.
• Retain provider statements, original transaction exports and purchase evidence.
• Record wallet transaction identifiers and evidence of your own transfers.
• Separate rewards, compensation, trading activity and fees in your working records.
• Preserve residence self-certifications and correspondence about corrections.
• Prepare a list of unresolved transactions before consulting an adviser.

This guide is informational and is not official tax advice or a personalised assessment. Whether a transaction is taxable, whether a return is required and how residence affects the answer depend on the applicable rules and your circumstances. Obtain qualified advice where a relocation, disputed residence or incomplete transaction history could materially affect your decision.

Your next practical step is to check each provider’s residence records and export your transaction history. Resolve missing evidence before you need it for a return or a major spending decision. Accurate records will help you respond to reporting requests and obtain advice on the separate question that matters for your finances: what you actually need to declare and pay.
