This unique 13-digit identifier remains unchanged throughout a person&#8217;s lifetime and serves as the primary link between individuals and Swiss tax authorities.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the tax ID used for?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The primary purpose of the TIN is to uniquely identify individuals residing in Switzerland for tax reporting and various administrative processes<\/strong> related to pensions and social security. The TIN also helps facilitate smooth international automatic exchange of information (AEOI) and thus enhances global tax compliance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specifically, the TIN is used in the following contexts:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Filing income tax returns with Swiss authorities<\/li>\n\n\n\n<li>Facilitating identification for tax audits and assessments<\/li>\n\n\n\n<li>Reporting income from employment or financial institutions<\/li>\n\n\n\n<li>Linking individuals to their contributions and benefits under old-age and survivors\u2019 insurance schemes (AHV\/IV\/EO)<\/li>\n\n\n\n<li>Participating in international tax agreements, such as the Automatic Exchange of Information (AEOI), which allows Swiss authorities to share financial information with other countries to prevent tax evasion<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">How is the tax ID assigned and where can it be found?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>In Switzerland, the personal tax ID corresponds to a person\u2019s social insurance (AHV) number.<\/strong> This is assigned to natural persons shortly after their birth if they are born and live in Switzerland, and never changes from that day forward.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Foreign-born nationals who become tax residents of Switzerland receive their tax ID when they register with the Swiss tax authorities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As the tax ID remains the same throughout a taxpayer\u2019s life, and corresponds to their AHV number, it can easily be found in the following ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>From their employer if they are in a full-time employment relationship,<\/li>\n\n\n\n<li>Their health insurance card if they are insured in Switzerland,<\/li>\n\n\n\n<li>From the compensation fund.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">How is the tax ID constructed?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The AHV number (or TIN) in Switzerland consists of 13 digits separated by three dots. It is structured as follows:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Digits 1 \u2013 3:<\/strong> The first three digits represent the country code, which is \u201c756\u201d for Swiss AHV numbers.<\/li>\n\n\n\n<li><strong>Digits 4 \u2013 12:<\/strong> The next nine digits are randomly generated, and therefore contain no personal information of the individual.<\/li>\n\n\n\n<li><strong>Digit 13:<\/strong> The final digit is a check digit calculated using the EAN-13 system. This is computed based on a specific mathematical formula that checks for data entry errors.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Here is an example of what the tax identification number looks like:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>756.3210.9876.06<\/strong><strong><\/strong><\/p>\n<div class=\"cta-block\"><p class=\"blog-section-content\">Book a free initial consultation with our experts.<\/p><a class=\"cta-button\" href=\"https:\/\/www.nexova.ch\/en\/book-a-call\/\">Book a call<\/a><\/div><\/div><\/section>\n\n\n\n<section class=\"wp-block-qweb-blog-section blog-section\"><div class=\"blog-section-wrap\"><h2 class=\"blog-section-title\">What is the company identification number (UID) and why do businesses need it?<\/h2>\n<figure class=\"wp-block-image size-full resp\"><picture><source srcset=\"https:\/\/www.nexova.ch\/wp-content\/uploads\/2025\/01\/AdobeStock_177749872_2-edited.jpg\" media=\"(min-width: 981px)\"\/><source srcset=\"https:\/\/www.nexova.ch\/wp-content\/uploads\/2024\/09\/AdobeStock_177749872_2.jpg\" media=\"(max-width: 980px)\"\/><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" alt=\"\" class=\"lazyload wp-image-21244\"\/><\/picture><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Where individuals are assigned a tax ID, companies and legal entities in Switzerland are assigned a uniform company identification number (UID).<\/strong> The UID is used to uniquely and permanently identify companies in all their interactions with authorities. Since 2011, this number has replaced all previous identification numbers used in public administration, such as the VAT Number and commercial register number.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the UID number used for?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The UID is the universal identification number for businesses in Switzerland<\/strong>. It is used not only for tax purposes but across all national administrative and legal processes, making it a key component of a company\u2019s interactions with Swiss authorities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>It serves multiple purposes, including:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Identifying companies in all administrative, legal, and tax-related interactions with authorities<\/li>\n\n\n\n<li>Managing transactions with federal agencies, customs, and tax authorities<\/li>\n\n\n\n<li>Facilitating business registration and cross-sector operations<\/li>\n\n\n\n<li>Serving as the base identifier for VAT-related activities, especially for domestic tax compliance<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In essence, the UID simplifies communication between businesses and the Swiss government by consolidating various identification systems under one unified number.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How is the UID allocated and to whom?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The UID is automatically assigned to all companies registered in any Swiss administrative register linked to the UID system<\/strong>. These registers include, for instance, the AHV compensation fund, the commercial register, and the VAT register.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The term &#8220;company&#8221; is broadly defined within the UID system<\/strong>, encompassing not only traditional businesses (e.g., corporations, partnerships, and sole proprietorships) but also non-profit organizations such as foundations, associations, and public law entities, as well as foreign businesses operating within the country.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The UID ensures that each entity has a unique identifier for tax and administrative purposes<\/strong>. Even if a business engages in multiple sectors or activities, it will retain a single UID, which is used consistently across all its operations. In the public sector, municipalities and cantons are also assigned their own UIDs, as are the federal government, its departments, and federal offices.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What information does the UID register contain?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The UID register contains essential information on all companies and legal entities with a UID number in Switzerland.<strong> The data includes:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The company name,<\/li>\n\n\n\n<li>The registered domicile address,<\/li>\n\n\n\n<li>The legal form of the entity,<\/li>\n\n\n\n<li>VAT and commercial register entries if applicable,<\/li>\n\n\n\n<li>The legal status (active, in liquidation, etc.)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This information is publicly accessible and can be found through the <a href=\"https:\/\/www.uid.admin.ch\/Pages\/search.aspx?lang=en\" rel=\"nofollow noopener\" target=\"_blank\">UID register online<\/a>. The UID ensures transparency and simplifies business administration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How is the UID number constructed?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The UID is a nine-digit number formatted as &#8220;CHE-123.456.789&#8221;.<\/strong> The &#8220;CHE&#8221; prefix signifies that it is a Swiss identifier, followed by nine digits that are randomly assigned. The number may be written without the hyphen and dots, although it is generally preferred to include them. The UID remains the same for the life of the company and serves as a core identifier for all tax, legal, and administrative purposes.<\/p>\n<div class=\"cta-block\"><p class=\"blog-section-content\">Book a free initial consultation with our experts.<\/p><a class=\"cta-button\" href=\"https:\/\/www.nexova.ch\/en\/book-a-call\/\">Book a call<\/a><\/div><\/div><\/section>\n\n\n\n<section class=\"wp-block-qweb-blog-section blog-section\"><div class=\"blog-section-wrap\"><h2 class=\"blog-section-title\">What is the Value Added Tax Number (VAT Number) and when do companies need it?<\/h2>\n<figure class=\"wp-block-image size-large resp\"><picture><source srcset=\"https:\/\/www.nexova.ch\/wp-content\/uploads\/2024\/10\/shutterstock_1571618281_2-edited-2-scaled.jpg\" media=\"(min-width: 981px)\"\/><source srcset=\"https:\/\/www.nexova.ch\/wp-content\/uploads\/2023\/12\/shutterstock_1571618281_2-768x512.jpg\" media=\"(max-width: 980px)\"\/><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" alt=\"\" class=\"lazyload wp-image-12613\"\/><\/picture><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Companies in Switzerland need a VAT Number when their annual turnover exceeds CHF 100,000<\/strong> or when they voluntarily register for VAT. The VAT Number is based on the company&#8217;s <strong>Company Identification Number (UID)<\/strong> with the suffix &#8220;<strong>MWST<\/strong>&#8221; and is automatically assigned by the Federal Tax Administration upon registration. It is used to handle VAT obligations within Switzerland.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the VAT Number used for?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>VAT Number<\/strong> is particularly used to facilitate the processing and collection of VAT domestically by uniquely identifying companies registered for VAT. The VAT Number serves the following purposes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Assistance in collecting VAT<\/strong> on behalf of the Swiss authorities when selling goods or services.<\/li>\n\n\n\n<li><strong>Reclaiming VAT<\/strong> on eligible business expenses.<\/li>\n\n\n\n<li><strong>Facilitating accounting and reporting<\/strong> related to VAT.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For companies operating in Switzerland, the VAT Number is essential to ensure compliance with national tax laws.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When is the VAT Number assigned and how is it structured?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>VAT Number<\/strong> is automatically assigned to companies by the <strong>Federal Tax Administration (FTA)<\/strong> as soon as they register for VAT. In Switzerland, companies are generally required to register for VAT if their annual turnover exceeds <strong>CHF 100,000<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Important Notes:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Exemptions<\/strong>: Certain activities may be exempt from VAT obligations.<\/li>\n\n\n\n<li><strong>Foreign Companies<\/strong>: Companies based abroad that provide services in Switzerland must register for VAT under certain conditions, regardless of turnover.<\/li>\n\n\n\n<li><strong>Voluntary Registration<\/strong>: Companies with lower turnover can voluntarily register for VAT.<\/li>\n\n\n\n<li><strong>Registration timeline:<\/strong> The FTA usually processes VAT registrations within approximately 3\u20134 weeks. Foreign companies without a registered office in Switzerland must appoint a fiscal representative in Switzerland to handle all VAT correspondence and compliance matters.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">How does the Swiss VAT Number differ from EU VAT Identification Numbers?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The Swiss VAT Number is only used to manage VAT obligations within Switzerland and is therefore not recognized within the EU for intra-community transactions.<\/strong> This means Swiss companies must obtain separate VAT identification numbers in EU countries where they conduct business.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In Switzerland, the <strong>Value Added Tax Number (VAT Number)<\/strong> is used to identify companies that provide services subject to VAT. This number is based on the <strong>Company Identification Number (UID)<\/strong> and is used to manage VAT obligations within Switzerland.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the <strong>European Union<\/strong>, on the other hand, the <strong>VAT Identification Number<\/strong> is used to uniquely identify companies for intra-community transactions. However, the designation of this number varies from country to country:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Germany<\/strong>: <strong>USt-IdNr.<\/strong> (Umsatzsteuer-Identifikationsnummer)<\/li>\n\n\n\n<li><strong>Austria<\/strong>: <strong>UID-Nummer<\/strong> (Umsatzsteuer-Identifikationsnummer)<\/li>\n\n\n\n<li><strong>Other EU Countries<\/strong>: Designations like <strong>VAT Number<\/strong>, <strong>VAT Identification Number<\/strong>, <strong>NIF<\/strong> (N\u00famero de Identificaci\u00f3n Fiscal), etc.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Key Points:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Validity and Recognition<\/strong>: The Swiss VAT Number is <strong>not<\/strong> recognized in the EU as a valid VAT Identification Number. Therefore, Swiss companies cannot use their VAT Number for intra-community supplies or services within the EU.<\/li>\n\n\n\n<li><strong>Applying for an EU VAT Identification Number<\/strong>: Swiss companies conducting VAT-taxable business in the EU must register for VAT in the respective EU member state. They will receive a local VAT Identification Number of the respective country.<\/li>\n\n\n\n<li><strong>Use of the Term &#8220;USt-ID&#8221; in Switzerland<\/strong>: Although the term &#8220;USt-ID&#8221; is specifically used in Germany, it is less common in Switzerland. In Switzerland, the official term is the <strong>Value Added Tax Number (VAT Number)<\/strong>. However, due to close economic ties with Germany, the term &#8220;USt-ID&#8221; may be known in Switzerland, especially in cross-border trade.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Note for Swiss Companies:<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">If you, as a Swiss company, wish to conduct business within the EU, you may need to register for VAT in one or more EU countries and apply for a corresponding VAT Identification Number of the respective country. This allows you to comply with EU VAT regulations and entitles you, under certain conditions, to benefit from VAT exemption for intra-community supplies.<\/p>\n<div class=\"cta-block\"><p class=\"blog-section-content\">Book a free initial consultation with our experts.<\/p><a class=\"cta-button\" href=\"https:\/\/www.nexova.ch\/en\/book-a-call\/\">Book a call<\/a><\/div><\/div><\/section>\n\n\n\n<section class=\"wp-block-qweb-blog-section blog-section\"><div class=\"blog-section-wrap\"><h2 class=\"blog-section-title\">Summary of Differences Between Tax ID, UID, and VAT Number<\/h2>\n<figure class=\"wp-block-image size-full resp\"><picture><source srcset=\"https:\/\/www.nexova.ch\/wp-content\/uploads\/2025\/01\/AdobeStock_330181771-edited.jpeg\" media=\"(min-width: 981px)\"\/><source srcset=\"https:\/\/www.nexova.ch\/wp-content\/uploads\/2024\/09\/AdobeStock_330181771.jpeg\" media=\"(max-width: 980px)\"\/><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" alt=\"\" class=\"lazyload wp-image-21246\"\/><\/picture><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Below is a brief overview of the key differences between the three tax identifiers we have examined in Switzerland:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Personal Tax Identification Number (TIN)<\/strong>: A 13-digit number assigned to individuals for personal tax purposes, mainly used for income tax returns, social security, and international tax reports.<\/li>\n\n\n\n<li><strong>Company Identification Number (UID)<\/strong>: A nine-digit number assigned to companies, used for all national administrative, legal, and tax interactions.<\/li>\n\n\n\n<li><strong>Value Added Tax Number (VAT Number)<\/strong>: An extension of the UID with the specific suffix &#8220;MWST&#8221;, required for handling <a href=\"https:\/\/www.nexova.ch\/en\/accounting\/value-added-tax-in-switzerland\/\" data-type=\"post\" data-id=\"6553\">VAT obligations within Switzerland<\/a>.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">While the <strong>TIN<\/strong> is used by individuals, the <strong>UID<\/strong> and <strong>VAT Number<\/strong> apply to companies, with the <strong>VAT Number<\/strong> specifically relating to VAT obligations within Switzerland.<\/p>\n<div class=\"cta-block\"><p class=\"blog-section-content\">Book a free initial consultation with our experts.<\/p><a class=\"cta-button\" href=\"https:\/\/www.nexova.ch\/en\/book-a-call\/\">Book a call<\/a><\/div><\/div><\/section>\n\n\n    <section class=\"wp-block-qweb-blog-conclusion blog-section conclusion\">\n        <div class=\"blog-section-wrap\">\n                            <h2 class=\"blog-section-title\">Need help with Swiss tax identification numbers?

Switzerland participates in the AEIO to ensure transparency and prevent tax evasion. The TIN is used to track individuals under the AEIO.<\/p><\/div><div class=\"faq-block\"><div class=\"faq-title\"><h3>How do you find your tax ID?<\/h3><span class=\"plus-ico\"><\/span><\/div><p class=\"faq-text\" style=\"\">Individuals can find their TIN on <strong>official tax document<\/strong>s such as tax returns or correspondence from Swiss tax authorities. It can also be found on their <strong>health insurance card<\/strong>, from their full-time employer, or from the compensation office.<br>Businesses can access their UID and <strong>VAT ID<\/strong> via registration documents or through the <strong>UID register online.<\/strong><\/p><\/div><div class=\"faq-block\"><div class=\"faq-title\"><h3>Do foreign companies need a UID?<\/h3><span class=\"plus-ico\"><\/span><\/div><p class=\"faq-text\" style=\"\">Yes, <strong>foreign companies<\/strong> operating in Switzerland receive a <strong>UID<\/strong> to comply with Swiss tax regulations. The <strong>UID<\/strong> is automatically assigned to them as soon as they register with a competent authority, for example in the <strong>commercial register<\/strong> or with the <strong>Federal Tax Administration<\/strong>. This is necessary regardless of turnover if they provide certain services or make deliveries.<\/p><\/div><div class=\"faq-block\"><div class=\"faq-title\"><h3>When is a VAT Identification Number mandatory?<\/h3><span class=\"plus-ico\"><\/span><\/div><p class=\"faq-text\" style=\"\">A <strong>Value Added Tax Number (VAT Number)<\/strong> is mandatory for companies with an annual turnover exceeding <strong>CHF 100,000<\/strong> from taxable services in Switzerland. Companies with lower turnover can voluntarily register for <strong>VAT<\/strong>. <strong>Foreign companies<\/strong> providing services in Switzerland must register under certain conditions, regardless of turnover.<\/p><\/div><div class=\"faq-block\"><div class=\"faq-title\"><h3>Which tax identification numbers do legal entities need in Switzerland?<\/h3><span class=\"plus-ico\"><\/span><\/div><p class=\"faq-text\" style=\"\">Legal entities, i.e. companies and other legal <strong>entities<\/strong>, receive a <strong>company identification number (UID)<\/strong> in Switzerland. This number serves as the central <strong>Swiss tax ID<\/strong> and is issued by the <strong>tax administration<\/strong>. By law <strong>,<\/strong> the UID is required for all administrative and tax <strong>matters<\/strong>. It enables the company to be clearly identified to the authorities and simplifies tax processes. The UID is assigned automatically when a company is founded or registered.<\/p><\/div><\/div><\/div><\/section>\n\n\n<section class=\"wp-block-qweb-company-review blog-section company-review\">\n\t<div class=\"blog-section-wrap\">\n\t\t<h2 class=\"section-title\">Trusted by over 250 companies<\/h2>\n\t\t<p class=\"tx-large-size\">Discover the diversity of our customers<\/p>\n\t\t<div class=\"q_company_reviews\">\n\t\t\t\t\t\t\t<div class=\"reviews_col\">\n\t\t\t\t\t<div class=\"review_wrap\" style=\"background-color:#eeedf7\">\n\t\t\t\t\t\t<div class=\"review_logo\">\n\t\t\t\t\t\t\t<div class=\"logo_wrap\" style=\"background-color:#7864c8\">\n\t\t\t\t\t\t\t\t<img class=\"img-responsive responsive--  wp-post-image\" title=\"logo image\" src = \"https:\/\/www.nexova.ch\/wp-content\/uploads\/2023\/11\/sphero-1.png\" \/>\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"review_head\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"avatar\" style=\"background-image:url('https:\/\/www.nexova.ch\/wp-content\/uploads\/2025\/05\/1633271859535.jpeg')\">\t\t\t\t\t\t\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"title\">\n\t\t\t\t\t\t\t\t<div class=\"reviewer\">\n\t\t\t\t\t\t\t\t\tJan Lichtenberg\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<div class=\"date\">\n\t\t\t\t\t\t\t\t\tCEO, InSphero AG\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"review_content\">\n\t\t\t\t\t\t\t<p class=\"p1\">As an internationally active biotechnology company that stands for innovation and the highest quality, we work exclusively with partners who meet our high standards.
