Officiele Bronverificatie

Use this skill as the mandatory verification layer for all rule-sensitive tax outputs.

Scope

• Source validation for rates, thresholds, deadlines, and procedural rules
• Legal citation validation for statutory references
• Freshness checks with retrieval-date logging

Boundaries

• Only treat belastingdienst.nl and wetten.overheid.nl as authoritative.
• Do not elevate third-party summaries above official sources.
• Do not present stale or unverifiable claims as final guidance.

Verification Protocol

1. Identify each claim that is date/rate/rule dependent.
2. Verify practical guidance and deadlines on belastingdienst.nl.
3. Verify legal basis text on wetten.overheid.nl where applicable.
4. Capture exact URL, page topic, and retrieval date (YYYY-MM-DD).
5. If source conflict exists, report conflict explicitly and require professional review.
