Why does my bank in Denmark ask where my cash comes from?

The duty to know the customer

Answered at: Checked at:

Short answer

As of November 2026, Danish banks are required by the anti-money laundering act to know all their customers well. They may ask about your income, expected payments abroad, how much cash you deposit, and the reason for large withdrawals, deposits or transfers abroad. They must also check your identity against an independent source, so it is not enough that you give the details yourself. If you do not answer, the bank may have to end the customer relationship.

Practical info

Why

  1. Banks must spot and report possible money laundering and terrorist financing.
  2. Questions are a normal part of the customer check, not an accusation.
  3. The bank must keep its information about you up to date.

Details

When a bank reports a suspicious transaction, it may not inform the customer, and such a report is not the same as a police complaint.

Tip

Answer the questions briefly and attach documents; it is usually the quickest way to get your payment through.

What may differ

If you disagree with the bank, complain to its complaints officer first and then to Det Finansielle Ankenævn.

Common misconception

A bank only asks questions when it suspects you of a crime.

What actually happens

Banks ask all customers questions as part of their legal duty to know them.
