This agreement, which was published in the Official Gazette on 1 September 1970, came into force on the same day. 

As a general rule, workers who move abroad are subject to the Social Security legislation of the country where they are working. However, if this is a temporary transfer, they can remain under Spanish legislation under the terms and requirements given below.

This is applicable only to workers who are not citizens of European Union countries nor of Switzerland.

Initial move

For workers employed by another person who work for a Spanish company and are sent by it to work temporarily in Switzerland, the corresponding transfer certificate should be applied for at a Provincial or Administrative Office of the General Treasury of the Social Security.

Self-employed workers cannot invoke this section to remain under Spanish Social Security legislation during their transfer to Switzerland. However, they can make an application under the terms of the section "Other Exceptions".

Application form

The company must make the application on form TA.200  "Application to remain under Spanish Social Security legislation - Initial transfers" and also form CH/E.1 "Transfer certificate", filled in in triplicate.

The form issued by the local Provincial or Administrative Office certifies that the worker continues to be subject to Spanish Social Security legislation during his or her stay in that country and therefore is exempt from Swiss Social Security contributions.

Period of authorisation 

The maximum length of time for the transfer is 24 months

Ordinary extension

If employees have to extend their stay in that country for more than the initial two years, the employer must apply to the General Sub-Directorate for Affiliation and Special Procedures of the Treasury General of the Social Security for an extension to remain under Spanish Social Security legislation. This must be done far enough in advance before the end of the authorised period.

Application form

The application for an extension must be made on form TA.202  "Application to remain under Spanish Social Security legislation in accordance with |art. 117 of the EEC  Regulation 1408/71 and other extensions of Bilateral Agreements".

Once the Swiss Social Security system has given its consent, the General Sub-Directorate for Affiliation and Special Procedures of the Treasury General of the Social Security will issue form CH/E., certifying that the worker continues to be subject to Spanish Social Security legislation for the authorised period.

Period of authorisation 

There is no maximum length of time for the extension.

Other transfers

The Provincial or Administrative Offices of the Social Security Treasury General.

Are the bodies with the power to authorise transfers for:

• Itinerant personnel of transport companies with their headquarters in Spain.
• Crew members of ships flying the Spanish flag.

The authorisation is issued on form CH/E-1 "Transfer certificate". Form TA-200 must be submitted along with this form filled in in triplicate.

Other exceptions

Applications for other exceptions are processed by the General Sub-Directorate for Affiliation and Special Procedures of the Treasury General of the Social Security.

The application for an extension must be made by the company or self-employed worker on form TA.202 "Application to remain under Spanish Social Security legislation under the terms of art.17 of EEC Regulation 1408/71 and other extensions of Bilateral Agreements"".

Once the Swiss Social Security system has given its consent, the General Sub-Directorate for Affiliation and Special Procedures of the Treasury General of the Social Security will issue form CH/E.1, certifying that the worker continues to be subject to Spanish Social Security legislation for the authorised period.

The Treasury General of the Social Security (General Sub-Directorate for Affiliation and Special Procedures) processes applications for airline workers who are expatriated to Switzerland and issues, upon the request of the company, form CH/E-1 "Expatriation certificate", which is valid for the full duration of the expatriation.

Health Care

The Agreement only includes healthcare caused by work-related injuries and occupational diseases. At the request of the Swiss authorities, the Provincial Office of the National Social Security Institute will issue the corresponding certificates.
