|---|---|
| Automatic for disputed portion | If bezwaar includes payment postponement request, collection is suspended for the disputed amount |
| Undisputed portion | Must still be paid by original deadline |
| Interest | Belastingrente continues to accrue during postponement |
| Legislation | Article 25 Invorderingswet 1990 |

| Partially granted | Review residual difference; consider beroep for remainder |

| Deadline | 6 weeks from uitspraak op bezwaar |
| Court | Rechtbank (sector bestuursrecht / belastingkamer) |
| Court fee (griffierecht) | EUR 53 (individuals) / EUR 365 (legal entities) — 2025 |
| Process | Written procedure; may include oral hearing (zitting) |

Conservative Defaults
| Situation | Default |
|---|---|
| Deadline calculation uncertain | Assume shortest possible deadline — file immediately or pro forma |
| Grounds partially supported by evidence | File on supported grounds only; flag unsupported for further documentation |
| Legal interpretation unclear | State the most conservative interpretation; flag for professional review |
| Payment postponement: unclear if automatic | Always request explicitly in the letter |
| Hoorzitting offered | Always accept — right to be heard strengthens position |
| Representative without machtiging | Do NOT file — obtain signed power of attorney first |
| Ambtshalve vs bezwaar unclear | If within 6 weeks: file bezwaar (preserves appeal rights) |
Escalate to a qualified belastingadviseur or belastingadvocaat when:
⚠️ DISCLAIMER: This skill provides workflow and drafting support only and does not constitute legal or tax advice. All bezwaar letters and tax correspondence must be reviewed and signed off by a qualified Dutch belastingadviseur or belastingadvocaat before submission.
