Confirm period, registration context, and transaction profile. 2. Reconcile sales/purchase evidence to VAT categories. 3. Identify anomalies and missing invoice support. 4. Produce filing readiness output with risk notes. ## Official Source Verification 1. Verify filing deadlines and practical instructions on `belastingdienst.nl`. 2. Verify legal wording when needed on `wetten.overheid.nl`. 3. Log URL + retrieval date for each rule-sensitive statement. 4. Mark unverifiable claims as non-final. ## Escalation Points Escalate when: - Cross-border VAT treatment is uncertain - Reverse-charge or special regime treatment is unclear - Material period-over-period deviations lack explanation - High-value corrections are needed ## Safety This skill supports process quality and does not replace professional fiscal advice. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/johnhout) — claim your Tome and manage your conversions.
