Before you start
Prepare every page and enclosure. Keep the original to check deadlines, amounts and references. Quote the reference number when contacting the authority and follow the recipient’s language requirements.
Objection: 30 days
For tax assessment decisions, this deadline cannot be extended. A tax-return filing extension does not change it. Missed deadlines are subject to specific reinstatement conditions.
