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

Identify each claim that is date/rate/rule dependent.

Verify practical guidance and deadlines on belastingdienst.nl.

Verify legal basis text on wetten.overheid.nl where applicable.

Capture exact URL, page topic, and retrieval date (YYYY-MM-DD).

If source conflict exists, report conflict explicitly and require professional review.

If source unavailable, mark claim as unverified and stop short of definitive guidance.

Escalation Points

Escalate when:

Official sources appear to conflict

No current source confirms a high-impact claim

Filing or objection timing is near and unresolved

Safety

This skill enforces quality and recency controls; it does not replace professional legal or fiscal advice.
