On 5 October 2026, the Dutch Tax and Customs Administration (Belastingdienst) opened registration for the annual Intermediairdagen (Intermediary Days) 2026, scheduled to run from 3 November to 1 December 2026 across eight locations nationwide. These events represent the primary engagement platform between the tax authority and the professional tax intermediary community — including tax advisors, accountants, payroll administrators, and legal practitioners — who collectively handle the vast majority of tax filings and compliance interactions in the Netherlands. The 2026 edition focuses on the practical implementation of recent legislative changes, including the 2027 Tax Plan (Belastingplan 2027) presented on Prinsjesdag, updates to the General Tax Act (Algemene wet inzake rijksbelastingen), and the rollout of new digital services such as the expanded “Overzicht betalen en ontvangen” portal. The sessions are designed to provide intermediaries with direct access to policy makers, audit specialists, and IT architects from the Belastingdienst, enabling them to clarify ambiguities, signal implementation challenges, and influence future service design.
Key Takeaways
- Comprehensive Regulatory Update Program: The agenda covers critical topics including the new corporate income tax payment integration, upcoming e-invoicing mandates, changes to the innovation box regime, adjustments to the 30% ruling for expatriates, and enhanced reporting requirements for cross-border arrangements under DAC6 and CRS. Special sessions address the Belastingdienst’s “Aanpak Verhuld Vermogen” (Hidden Wealth Approach) enforcement strategy, which recovered €139 million in 2025.
- Interactive Format with Practical Case Studies: Unlike traditional webinars, the Intermediary Days feature live demonstrations of new digital tools, breakout workshops on complex audit scenarios, and Q&A panels with senior tax inspectors. Participants receive certified CPE credits recognized by professional bodies such as NOB, NBA, and VRT.
- Strategic Feedback Loop for Tax Administration: The Belastingdienst explicitly uses these events to gather frontline intelligence from intermediaries who encounter practical application issues daily. This feedback directly informs the “uitvoeringstoetsen” (implementation tests) that assess the feasibility of new tax legislation before it becomes law, ensuring that policy intentions translate into workable compliance processes.
