In 2022 the Finnish Centre for Pensions issued instructions on when to apply for the A1 certificate for work abroad. These instructions have been interpreted in a way that the certificate would be required even for a one day business trips. The instructions have now been updated and there is no need to apply for an A1 certificate for short conferences, business or recreational trips abroad unless it is known that the receiving country requires the certificate. If needed, the A1 certificate can be applied for retrospectively. Such a need may arise due to a requirement by the receiving country or if an occupational accident occurs during the trip. However, if the work abroad is performed at a construction site or a factory, presenting the A1 certificate may be required for the employee to get onto the site regardless of the length of the stay.
