Scope

Box-based classification support (box 1, box 2, box 3)

Filing-readiness checklist and issue flags

Boundaries

Do not decide final tax position without verified support.

Do not provide binding legal interpretation.

Keep uncertain positions explicitly labeled.

Workflow

Reconcile supplied figures with supporting documents.

Flag missing support, anomalies, and prior-year carryover risks.

Build stepwise filing-preparation checklist.

Official Source Verification

For rates, thresholds, criteria, and deadlines:

Verify on belastingdienst.nl.

Verify legal references on wetten.overheid.nl.

Include URL and retrieval date in outputs.

Mark non-verified items as pending professional confirmation.

Escalate when:

Cross-border assets/income exist

Material discrepancies are unresolved

Time-sensitive filing risk is high
