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.

Tip: Failing to deregister can cause problems with tax, health insurance, banks, and mail delivery. Notify authorities before you leave.

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.
