We handle the A1 certificate application of each worker so that they keep contributing to the Spanish Seguridad Social (Social Security) while working in another EU or EEA country, Switzerland or the United Kingdom. One single application for the whole team: the company adds each worker and the price is per worker. If you are a company posting your workers to the Netherlands, we also handle the notification on the Dutch posted workers portal, the site documents in English, the check of the Dutch minimum pay and, if needed, the residence permit of workers from outside the EU, the EEA and Switzerland.

A1 posting certificate (form TA.300): how is it filed?

  1. 11. Say whether you are self-employed and travelling yourself, or a company posting its workers. A company adds all of them here, one card each.
  2. 22. Give the country of destination and the dates. If it is the Netherlands, add each site and answer the questions about the work.
  3. 33. We file one A1 certificate per worker with the Tesorería General de la Seguridad Social (Social Security General Treasury) and, in the Netherlands, the notification of each site on the posted workers portal.
  4. 44. We send you each A1 certificate as a PDF and, in the Netherlands, the documents that must be kept on site, prepared in English.

Which documents do you need?

  • •If the application is made by a company: the deed or power of attorney of the person signing for it, which the Seguridad Social requires to accept that we file on its behalf.
  • •If it is a company and the destination is the Netherlands: the employment contract and latest payslip of each worker, to prepare the site documents and check the pay the Netherlands requires.
  • •If it is a company, the destination is the Netherlands and any worker is not from the EU, the EEA or Switzerland: their Spanish residence and work authorisation (TIE), and the passport of those who need the Dutch residence permit.

Legal basis and things to bear in mind

  • The A1 certificate is compulsory. Working abroad without it can lead to a requirement to register and pay contributions in the country of destination, as well as possible penalties.
  • To keep contributing in Spain, the worker must have been registered with the Seguridad Social for at least one month before leaving and keep their Spanish employment contract, the company must keep its usual activity in Spain, and the worker cannot be sent to replace another posted worker. If any of these points is not met, tell us in the description and we will explain the alternative.
  • In the Netherlands, workers are paid from day one at least the Dutch minimum wage and, if their sector has a generally binding collective agreement, what that agreement sets for their category (in construction, the Bouw & Infra agreement), and if the posting exceeds 12 months (18 with a reasoned notification) all Dutch employment law applies. A worker who replaces another in the same task and site adds their time to that of the worker replaced for those periods.
  • The documents that must be kept on the Dutch site (contract, payslips, time records, A1 and proof of payment of wages) must be in Dutch, English, German or French: Spanish is not accepted. We prepare them in English.
  • If a new worker joins later, they go in a new application with only the new ones. If it is for a site we already notified for you, mark it in the question about the sites and the site is not charged again.
