How to Deregister (Udrejse) When You Leave Denmark
Leaving Denmark for more than 6 months? You must officially deregister your address (“udrejse”). Here’s when you need to do it, the exact steps, what happens to your CPR, and the links you’ll use.
Overview: What “udrejse” means and why it matters
🪪 Legal obligation
If you move abroad for 6+ months, you must register your departure with the National Register (Folkeregister).
👨👩👧 Applies to everyone
Citizens, expats, students, children—each person must be deregistered individually (parents do it for minors).
⚠️ If you don’t
You risk tax issues, insurance gaps, bank/CPR conflicts, fines, and missed government mail.
How to deregister: your options
💻 Online (easiest)
Log in with MitID at borger.dk/udrejse and submit the departure form. You can do this from abroad.
🏛️ In person
Visit your local Borgerservice if you lack MitID or have issues. Bring ID, CPR, and your new foreign address.
🌍 Already abroad
Still use borger.dk. If you cannot log in, contact the last municipality where you lived in Denmark.
When do you need to deregister?
📆 6+ months away
You must deregister if you’ll be outside Denmark for more than six months—even if you plan to return.
⏱️ Under 6 months
No deregistration needed if gone under six months and you keep a permanent address in Denmark.
🎓 Students & families
Year-abroad students must deregister if away 6+ months. Parents must submit for their children.
Step-by-step: completing your “udrejse”
📝 1) Gather details
CPR number, departure date, and your new foreign address (as complete as possible).
🔐 2) Log in & fill form
Go to borger.dk/udrejse, log in with MitID, and complete the online form.
✅ 3) Submit & save proof
Submit and save/print your confirmation for records, landlords, banks, and schools.
📣 4) Notify others
Inform your bank, landlord, insurer, GP, school, and the Danish Tax Agency (Skattestyrelsen).
After you deregister: what changes
🪪 CPR status
Your CPR becomes “inactive” but remains yours for life. Healthcare and most public benefits stop from your move date.
💸 Taxes & refunds
File your exit-year tax return at skat.dk. Link a foreign NemKonto to receive any refunds.
📬 Mail & e-Boks
e-Boks works abroad—ensure MitID access and update contact details. Set up PostNord mail forwarding if needed.
