GDPR and KYC: how data protection applies to identity checks on EU residents

The GDPR governs every piece of personal data a firm collects during customer due diligence. This page covers lawful basis, biometric and criminal offence data, retention, international transfers and the changes still under negotiation.

In brief
  • Processing needed to meet a legal obligation is lawful under Article 6(1)(c), but that obligation must come from EU or member state law (Art 6(3)). A foreign AML law does not qualify.
  • Biometric data used to uniquely identify a person is special category data under Article 9, and criminal offence data, which screening can surface, is restricted by Article 10.
  • From 10 July 2027 the EU AML Regulation sets a five-year retention period for CDD records and then requires deletion (AMLR Art 77).
  • Australia has no EU adequacy decision, so transfers of EU personal data to Australia need another safeguard under Chapter V.

What it is

What it is

The General Data Protection Regulation, Regulation (EU) 2016/679, is the EU's main data protection law. KYC sits at an awkward point in it. AML law requires firms to collect identity documents, beneficial ownership details and screening results, and the GDPR requires that collection to be lawful, limited, secure and time-bound.

The GDPR reaches beyond the EU. Under Article 3(2) it applies to a controller outside the EU that offers goods or services to people in the EU, or monitors their behaviour there. A non-EU firm in that position must usually appoint a representative in the EU (Art 27).

From 10 July 2027 the EU AML Regulation adds specific rules for KYC data: when special category and criminal offence data may be processed (Art 76) and how long records are kept (Art 77). Separately, the Commission proposed changes to the GDPR in its Digital Omnibus in November 2025. In October 2026 member states agreed their position, keeping the current definition of personal data. Negotiations with the Parliament have not finished.

Who it applies to

Who it applies to

The GDPR applies to anyone processing personal data in the context of an EU establishment, and to non-EU firms caught by Article 3(2).

  • Accountants, lawyers, notaries, estate agents and trust and company service providers in the EU doing CDD
  • Firms outside the EU, including in Australia, the UK and New Zealand, that offer services to clients in the EU
  • Vendors that verify identity or screen clients on a firm's behalf, as processors

The UK applies its own version, the UK GDPR, which this page does not cover.

The obligations

What you have to do

Each duty is matched to the kind of work where it bites. How you meet it is for your own privacy and AML programs to decide.

  1. Pick and record a lawful basis

    For CDD required by EU or member state law, Article 6(1)(c) applies. A firm whose AML duty comes from non-EU law needs another basis, such as legitimate interests under Article 6(1)(f), and should record why.

  2. Tell clients what you collect and why

    Explain at collection what data you process for AML checks. The AMLR makes this an express condition for processing special category data (Art 76(2)(a)).

  3. Treat biometric checks as special category data

    A selfie match used to uniquely identify someone needs an Article 9(2) exception, such as explicit consent or substantial public interest based on law. From July 2027, AMLR Article 76 permits processing that is strictly necessary to prevent money laundering, with safeguards.

  4. Handle criminal offence data from screening carefully

    Article 10 allows criminal offence data only under official authority or where EU or member state law authorises it. AMLR Article 76(3) adds that the data must relate to money laundering, predicate offences or terrorist financing, and that procedures must tell allegations apart from convictions.

  5. Keep records for the set period, then delete

    Apply storage limitation (Art 5(1)(e)). Under the AMLR, keep CDD records for five years after the relationship ends or the transaction or refusal, then delete them unless other law requires longer (Art 77(3)).

    Records policy
  6. Put a safeguard on international transfers

    Data can flow freely only to countries with an adequacy decision. For others, including Australia, use an Article 46 safeguard such as standard contractual clauses.

Commonly misread

What firms get wrong

Most errors come from treating the AML duty as a blanket permission.

Our AML law gives us a legal obligation basis for EU clients.

Article 6(3) says the legal obligation basis must come from EU law or the law of the member state the controller is subject to. An Australian or UK AML duty does not meet that test.

Keeping KYC files longer is the safe option.

Storage limitation applies, and the AMLR requires deletion once the five-year period ends unless another law requires more (Art 77(3)).

The Digital Omnibus has already changed the GDPR.

It is a proposal. Member states set their position in October 2026 and talks with the Parliament are still ahead, so the current text applies.

Questions

Questions people ask

What is the lawful basis for KYC under the GDPR?

For checks that EU or member state law requires, it is legal obligation under Article 6(1)(c). Firms whose duty comes from non-EU law usually need another basis, such as legitimate interests, and should document their assessment.

Is a selfie check biometric data under the GDPR?

When it is used to uniquely identify a person, yes. That makes it special category data under Article 9, which needs one of the Article 9(2) exceptions. See biometric identity verification.

How long can we keep KYC records?

Only as long as needed for the purpose. From 10 July 2027 the AMLR sets five years from the end of the relationship, then deletion unless another law requires longer. Before then, national AML laws set the period.

Does the GDPR apply to an Australian firm with EU clients?

It can. Article 3(2) covers non-EU firms that offer goods or services to people in the EU. Such firms usually need an EU representative too (Art 27).

What are the maximum GDPR fines?

For breaches of the core principles, lawful basis, special category rules, data subject rights or transfer rules, up to EUR 20 million or 4% of worldwide annual turnover, whichever is higher (Art 83(5)).

Where StackGo fits

Where StackGo fits

StackGo is compliance middleware. IdentityCheck runs the identity, screening and intake steps where most KYC personal data is created. The lawful basis, notices, retention policy and transfer safeguards remain the firm's decisions as controller.

What IdentityCheck covers today
  • Biometric identity verification: a photo of a government ID document plus a live selfie with liveness.
  • PEP, sanctions and adverse media screening, with ongoing monitoring of screened clients.
  • Two-way integrations with Xero Practice Manager, Xero, Karbon and HubSpot; Salesforce via Zapier. By default no personal details are written back to the connected system, only a link to the result plus the outcome and status, which limits copies of KYC data.
What it does not do
  • It does not choose a lawful basis, write privacy notices or set retention periods for you.
  • It gives no legal advice on the GDPR or on international transfers.
