What changed

ISDA and two partner associations submitted a joint response to the European Commission's call for evidence on the tax omnibus, specifically addressing beneficial ownership interpretation for withholding tax purposes. The response highlights that inconsistent beneficial ownership definitions across EU member states create significant tax uncertainty for dividends and interest in securities lending and derivatives, a problem the associations warn will intensify with the move to T+1 settlement. The associations propose a prospective EU-level principles-based framework aligned with OECD guidance but supplemented by clear practical rules and safe harbors for standard capital markets transactions.

Compliance teams at firms engaged in cross-border securities lending, repo transactions, and derivatives involving dividend or interest payments should monitor this consultation process. While no compliance deadline exists yet, the associations' call for harmonized EU-level rules suggests future regulatory changes could affect withholding tax procedures and beneficial ownership documentation requirements. Firms should review current beneficial ownership determinations and ensure tax positions are defensible under both existing member state interpretations and anticipated EU-level standards.

What to do next

Monitor European Commission developments on the tax omnibus consultation and potential beneficial ownership framework
Review current beneficial ownership determinations for securities lending and derivatives transactions against OECD guidance
Assess documentation practices for withholding tax exemptions to ensure consistency with emerging EU-level requirements

ISDA Responds to EC Call for Evidence on Tax Omnibus

The associations argue that inconsistent interpretation of “beneficial ownership” among member states creates significant tax uncertainty for dividends and interest in securities lending and derivatives, a problem that will worsen with the move to T+1 settlement. They call for a prospective, EU‑level, principles‑based framework, aligned with guidance from the Organisation for Economic Co-operation and Development but supplemented by clear, practical rules and safe harbours for standard capital markets transactions, to ensure consistent withholding tax outcomes, reduce market fragmentation and keep anti‑avoidance rules separate from beneficial ownership determinations.
