RS 02002.148 How a Certificate of Coverage is issued Under the Agreement with Denmark

A. Process for issuing a certificate of coverage

The following steps describe the process for issuing a certificate of coverage:

  1. 1. 

    The employer (in the case of employment) or the worker (in the case of self-employment) writes to the appropriate authority requesting a certificate. NOTE: The employer's or worker's representative (e.g., attorney or accounting firm) may request the certificate on the employer's or worker's behalf.

  2. 2. 

    The Social Security Administration (in the case of U.S. certificates) or the Danish National Social Security Agency (in the case of Danish certificates) issues the certificate, if appropriate.

  3. 3. 

    The issuing agency sends the original and one copy to the requestor.

  4. 4. 

    If the person is employed, the employer or worker presents the certificate to the tax authorities in the other country when requested to do so.

  5. 5. 

    If the person is a self-employed U.S. citizen who is subject only to Danish laws under the agreement, he or she must attach a photocopy of the Danish certificate to his or her U.S. income tax return each year.

B. Procedure for requesting a certificate of coverage

1. Required information

Advise the person to provide the following information when writing to get a certificate of coverage:

  • Full name of worker;

  • Date and place of birth;

  • Country of permanent residence;

  • Country of citizenship;

  • U.S. Social Security number;

  • Danish Central Personal Registration (CPR) number, if known;

  • Name, relationship, and date of birth of family members accompanying the worker;

  • A statement indicating whether the employee remains an employee of the U.S. company while working in Denmark or becomes an employee of a Danish company.

    NOTE: If the worker is an employee of a Danish affiliate of an American employer, the request must indicate whether the American employer has entered into an agreement with the Internal Revenue Service (IRS) under section 3121(l) of the IRS Code and, if yes, the effective date of such an agreement.
