GDPR and Financial Data: What Small Businesses Must Know
Compliance & Regulation · 2026-02-20 · 7 min
Financial data is personal data under GDPR. If you process invoices, receipts, or bank statements containing personal information, you have GDPR obligations. Here is what they are.
GDPR applies to any data that can identify a natural person. Financial documents are full of personal data: names on invoices, bank account numbers on statements, addresses on receipts, and email addresses on digital purchases. If your business processes these documents for EU residents, GDPR applies to you.
The key obligations are straightforward: have a lawful basis for processing (legitimate interest or contract fulfillment for accounting data), store data securely, allow data subjects to access and delete their data, and report breaches within 72 hours. For accounting data, the lawful basis is typically contract fulfillment or legal obligation.
A common conflict arises between GDPR deletion rights and tax record retention requirements. Tax authorities typically require you to keep records for 5-10 years. You cannot delete financial records that you are legally required to retain, even if a data subject requests it. The retention obligation takes precedence, but you should inform the subject.
Practical steps: encrypt financial data at rest, use TLS for data in transit, restrict access to financial records to authorized personnel, keep an audit log of who accesses what, and choose accounting software hosted in the EU or with EU data residency guarantees. These measures satisfy GDPR requirements for most small businesses.
