Current rules in the EU regulations for social security2 provide that an employee who resides in a different country from where his or her employer is located can work up to 25 percent in the country of residence and remain covered by social security in the country of his or her employer. This threshold is often insufficient to teleworkers who are usually denied more work from home by their employers because that would change which country is competent for social security.
The Framework Agreement provides an option to employers and employees in which an employee can work up to 49.9 percent in the country of residence and maintain coverage under the social security scheme in the country of the employer. This introduces greater predictability and flexibility in managing the social security tax affairs of a cross-border worker who works from home. To make use of the Framework Agreement, the employer must apply for an A1 certificate, which generally does not apply retroactively except under few and limited exceptions.
