When employees work in member states other than their home country, they need an A1 certificate. It certifies that the employee or self-employed person remains subject to social security contributions in their home country\u2014based on Regulation (EC) No. 883\/2004 on the coordination of social security systems.<\/p>\n<p>Strict requirements apply to the issuance of an A1 certificate. Both the <a href=\"https:\/\/personalleasing-osteuropa.de\/en\/\">Employer<\/a> Both the employer and the employee must comply with these requirements.<\/p>\n<\/div><\/div><div class=\"g-cols wpb_row via_grid cols_1 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_top type_default stacking_default\" style=\"--columns-gap:3rem;\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2 class=\"plo-wissen-title\">What is the A1 certificate, and what is it used for?<\/h2>\n<p class=\"plo-article-text\">The A1 certificate (formerly the E101 certificate) is a standardized EU document that certifies which national social security system an employee is subject to when working across borders. It protects the employee from having to pay social security contributions in two countries at the same time and provides the host country\u2019s authorities with clarity regarding the person\u2019s social security status.<\/p>\n<p class=\"plo-article-text\">The certificate is required for anyone who will be working temporarily in another EU\/EEA country or in Switzerland\u2014whether as a posted worker, a self-employed person, a business traveler, or someone who works in multiple countries at the same time.<\/p>\n<div class=\"plo-highlight-box\">\n<h3>Important: Requirement to Carry<\/h3>\n<p>You must carry your A1 certificate with you at all times while working abroad. In some countries\u2014particularly France, Belgium, and Austria\u2014compliance with this requirement is strictly enforced. Failure to carry the certificate can result in substantial fines.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><div class=\"g-cols wpb_row via_grid cols_1 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_top type_default stacking_default\" style=\"--columns-gap:3rem;\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2 class=\"plo-wissen-title\">What are the requirements for applying for an A1 certificate?<\/h2>\n<p class=\"plo-article-text\">There are various requirements that must be met in order to apply for the A1 certificate.<\/p>\n<ul class=\"plo-article-list\">\n<li>The first requirement is that an employee has only one <strong>Temporary work abroad<\/strong> . The exact duration is not uniformly regulated and depends on the specific regulations governing temporary assignments. However, the maximum duration of an assignment may not <strong>24 months<\/strong> amount to.<\/li>\n<li>The second requirement is that the employee, in his or her home country, <strong>already integrated into the social security system<\/strong> must be. This is because the A1 certificate establishes and verifies that the employee or self-employed person remains subject to social security contributions in their home country.<\/li>\n<li>If the employment is long-term, responsibility for social security contributions may be transferred to the host country. The A1 certificate can only be issued in cases where <strong>This is not the case.<\/strong><\/li>\n<\/ul>\n<p class=\"plo-article-text\">If an employee is temporarily assigned to work abroad, that employee must remain employed by the employer. Part of the assignment is therefore the continuation of an existing employment relationship\u2014the employer retains the authority to issue instructions to the employee.<\/p>\n<p class=\"plo-article-text\">Furthermore, the A1 certificate can only be issued if the posted employee <strong>does not take over another employee's position<\/strong>, who had previously been seconded by the company. This condition is intended to prevent abuse of the benefits of an A1 certificate.<\/p>\n<p class=\"plo-article-text\">The criterion that the activity in the host country must <strong>not to establish a permanent residence<\/strong> ... This means that the employer cannot open a permanent establishment abroad where the employee would continue to be employed on a continuous basis.<\/p>\n<h3 class=\"plo-wissen-subtitle\">What does the A1 certificate for self-employed individuals look like?<\/h3>\n<p class=\"plo-article-text\">Also for <a href=\"https:\/\/personalleasing-osteuropa.de\/en\/services\/freelancer-in-eastern-europe\/\">Self-Employed Individuals<\/a> Similar conditions apply. A self-employed person must provide proof that their primary economic activity continues to take place in their home country. They can provide this proof, for example, through sales figures, the leasing of business premises, or customer contacts. If a self-employed person cannot provide this evidence, the issuance of an A1 certificate is generally denied.<\/p>\n<p class=\"plo-article-text\">Self-employed individuals may only engage in the work they are currently performing. This means they may not undertake long-term projects or establish other business relationships in the host country. They must continue to provide evidence that their activities are temporary and do not constitute a permanent economic activity in the host country.<\/p>\n<\/div><\/div><\/div><\/div><\/div><div class=\"g-cols wpb_row via_grid cols_1 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_top type_default stacking_default\" style=\"--columns-gap:3rem;\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2 class=\"plo-wissen-title\">What are the requirements for employers and employees?<\/h2>\n<h3 class=\"plo-wissen-subtitle\">Requirements for the Employer<\/h3>\n<p class=\"plo-article-text\">The employer must plan the employee\u2019s assignment abroad well in advance and submit the necessary applications. When submitting the application, both the purpose and the duration of the assignment must be clearly defined. It must be ensured that the work abroad is only temporary.<\/p>\n<p class=\"plo-article-text\">Important: The employee is not exempt from the <strong>labor laws of the host country<\/strong> exempt. The employer is required to comply with local labor laws and regulations\u2014including those regarding working hours, occupational safety, and minimum wages.<\/p>\n<p class=\"plo-article-text\">In addition to the regulations of the EU and the EEA, there are also <strong>bilateral agreements<\/strong> between individual countries that govern social security coverage for cross-border work. These may include additional requirements or exceptions that must be taken into account when applying for the A1 certificate. Employers and employees should thoroughly familiarize themselves with the regulations in the respective countries in advance.<\/p>\n<h3 class=\"plo-wissen-subtitle\">Requirements for Employees<\/h3>\n<p class=\"plo-article-text\">The employee must provide all necessary information. Once the employee has received an A1 certificate, he or she must carry it with them while working abroad. The authorities in some countries take the requirement to carry this certificate very seriously. In France, for example, the A1 certificate must always be carried. In other countries\u2014such as those in Scandinavia\u2014this requirement is enforced more leniently.<\/p>\n<div class=\"plo-table-wrapper\">\n<table class=\"plo-table\">\n<thead>\n<tr>\n<th>Country<\/th>\n<th>Frequency of inspections<\/th>\n<th>Special Features<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>France<\/td>\n<td>Very strict<\/td>\n<td>Must be presented immediately upon inspection; high fines<\/td>\n<\/tr>\n<tr>\n<td>Belgium<\/td>\n<td>Strict<\/td>\n<td>Advance registration via the Limosa system is required<\/td>\n<\/tr>\n<tr>\n<td>Austria<\/td>\n<td>Strict<\/td>\n<td>ZKO Report in Addition to the A1 Certificate<\/td>\n<\/tr>\n<tr>\n<td>Germany<\/td>\n<td>Medium<\/td>\n<td>Electronic Application Submission via DRV\/GKV<\/td>\n<\/tr>\n<tr>\n<td>Scandinavian countries<\/td>\n<td>Moderate<\/td>\n<td>Inspections are less frequent, but the obligation to provide proof remains<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><div class=\"g-cols wpb_row via_grid cols_1 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_top type_default stacking_default\" style=\"--columns-gap:3rem;\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2 class=\"plo-wissen-title\">What are the details of the application process for the A1 certificate?<\/h2>\n<p class=\"plo-article-text\">In most member states, it is now possible to submit an application electronically. In Germany, employees are insured through the German Pension Insurance or their health insurance provider. Self-employed individuals who are working abroad temporarily should contact the German Pension Insurance.<\/p>\n<h3 class=\"plo-wissen-subtitle\">Step 1: Submit an application for an A1 certificate<\/h3>\n<p class=\"plo-article-text\">This is done either by the employer or\u2014in the case of self-employment\u2014by the self-employed individual. The application must include the following information:<\/p>\n<ul class=\"plo-article-list\">\n<li>Personal Information (Name, Date of Birth, Social Security Number)<\/li>\n<li>Company Information (Name, Address, Employer Identification Number)<\/li>\n<li>Type of work and planned location in the host country<\/li>\n<li>Duration of the planned assignment<\/li>\n<li>Address of the client or the branch office in the host country<\/li>\n<li>For self-employed individuals: Information regarding business registration<\/li>\n<\/ul>\n<h3 class=\"plo-wissen-subtitle\">Step 2: Checking the Requirements<\/h3>\n<p class=\"plo-article-text\">The German Pension Insurance or health insurance provider then verifies whether the requirements for issuing the A1 certificate have been met\u2014in particular, whether the assignment is indeed temporary and whether the employee is already registered in the social security system.<\/p>\n<h3 class=\"plo-wissen-subtitle\">Step 3: Issuance of the A1 Certificate<\/h3>\n<p class=\"plo-article-text\">If all requirements are met, the A1 certificate is issued and sent to the applicant. In Germany, this is done electronically\u2014which saves time, as the certificate is available more quickly. From that point on, it is the employee\u2019s responsibility to carry the certificate with them at all times while working abroad.<\/p>\n<\/div><\/div><\/div><\/div><\/div><div class=\"g-cols wpb_row via_grid cols_1 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_top type_default stacking_default\" style=\"--columns-gap:3rem;\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2 class=\"plo-wissen-title\">Government Oversight \u2013 Measures in Case of Violations<\/h2>\n<p class=\"plo-article-text\">In recent years, authorities have significantly tightened inspections within the EU to ensure that employees and self-employed individuals comply with social security regulations. If an employee does not have the A1 certificate on hand during an inspection, both the employee and the employer face severe penalties\u2014in the worst case, even a ban on working in the host country.<\/p>\n<h3 class=\"plo-wissen-subtitle\">Language Requirements<\/h3>\n<p class=\"plo-article-text\">When it comes to the language of the certificate, EU countries are generally flexible\u2014the language of the home country is usually sufficient. However, as a precaution, it is advisable to have a translation made into the official language of the host country to avoid any misunderstandings during inspections.<\/p>\n<h3 class=\"plo-wissen-subtitle\">Change in Circumstances During the Assignment<\/h3>\n<p class=\"plo-article-text\">There are cases in which the circumstances of the assignment change\u2014for example, a change in the assignment location or an extension of the stay. In this case, a <strong>Updating the Certificate<\/strong> required. The employee may continue working only if he or she carries a current certificate.<\/p>\n<h3 class=\"plo-wissen-subtitle\">Short-Term Assignments and Emergency Procedures<\/h3>\n<p class=\"plo-article-text\">If an employee is to be posted on short notice, some countries offer emergency procedures or a provisional certificate. These are generally valid for a limited time, and an application for the regular A1 certificate must still be submitted retroactively. As a general rule: <strong>An employee may be sent abroad only if he or she carries a valid A1 certificate.<\/strong> A late application is not legally valid and may result in severe penalties.<\/p>\n<div class=\"plo-highlight-box\">\n<h3>Overview of Penalties for Violations<\/h3>\n<ul class=\"plo-checklist\">\n<li><i class=\"fas fa-check-circle\"><\/i>Fines for employers and employees (varies by state; may amount to several thousand euros)<\/li>\n<li><i class=\"fas fa-check-circle\"><\/i>Immediate suspension of work ordered by authorities in the host country<\/li>\n<li><i class=\"fas fa-check-circle\"><\/i>Prohibition on the Employee Working in the Host Country<\/li>\n<li><i class=\"fas fa-check-circle\"><\/i>Retroactive Collection of Social Security Contributions in the Host Country<\/li>\n<li><i class=\"fas fa-check-circle\"><\/i>Reputational damage to the borrowing company<\/li>\n<\/ul>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><h2 class=\"plo-wissen-title\">FAQ: Frequently Asked Questions About the A1 Certificate<\/h2>\n<\/div><\/div><div class=\"w-separator size_medium\"><\/div><div class=\"w-tabs plo-faq-list style_default switch_click accordion type_togglable has_scrolling\" style=\"--sections-title-size:inherit\"><div class=\"w-tabs-sections titles-align_none icon_triangle cpos_left\"><div class=\"w-tabs-section\" id=\"qeea\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"><button class=\"w-tabs-section-header\" aria-controls=\"content-qeea\" aria-expanded=\"false\"><div class=\"w-tabs-section-title\" itemprop=\"name\">Who needs an A1 certificate?<\/div><div class=\"w-tabs-section-control\"><\/div><\/button><div  class=\"w-tabs-section-content\" id=\"content-qeea\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"><div class=\"w-tabs-section-content-h i-cf\" itemprop=\"text\"><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><p>Any person who is temporarily working in another EU or EEA member state or in Switzerland and remains subject to social security contributions in their home country.
