Do not send ID numbers, bank account numbers or passwords. We cannot give legal or tax advice, or say whether a benefit will actually be approved. Please ask the relevant authority for that.
What happens next
Replies may take several business days, and we cannot promise a reply to every message. If a mistake is confirmed we fix the calculator and record the date in its update log. How the email is handled is described in the Privacy notice.
