Capture user profile and factual context. 2. Map potential deductions/regimes to evidence requirements. 3. Validate completeness and identify weak support. 4. Produce prioritized next actions. ## Official Source Verification 1. Verify criteria, limits, and timelines on `belastingdienst.nl`. 2. Verify legal references on `wetten.overheid.nl` when relevant. 3. Include URL + retrieval date for all rule-dependent statements. 4. Mark non-verified items as pending. ## Escalation Points Escalate when: - Qualification depends on nuanced legal interpretation - Multiple regimes conflict - Missing evidence could materially change outcome ## Safety This skill supports preparation and does not replace qualified tax advice. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/johnhout) — claim your Tome and manage your conversions.
