Select Your Legal Entity
The first step in company formation Basel is choosing the appropriate legal structure. For high-capital ventures, an Aktiengesellschaft (AG) is ideal, offering strong liability protection and access to public capital markets. The AG requires a minimum capital of CHF 100,000, with at least 20% paid in at formation. This structure is suitable for companies planning long-term growth, international expansion, or public listings. In contrast, a Gesellschaft mit beschränkter Haftung (GmbH) may be more appropriate for smaller businesses with lower capital needs. The Swiss Company Registration: Guide for Foreign Entrepreneurs provides a detailed comparison of all legal forms and their implications.

2-3 weeks
Prepare and Notarize Statutes
Once the legal form is selected, draft the company’s statutes (Gründungsurkunde) outlining governance, capital structure, and operational rules. This document must be notarized by a Swiss notary public, a mandatory step for all capital companies. The notarization fee varies based on the company’s capital, ranging from CHF 378.25 to CHF 16,215. The notary will verify the authenticity of signatures, ensure compliance with Swiss law, and issue a certified copy. After notarization, the company can proceed to register with the Commercial Register. For guidance on this process, refer to the Company Registration Switzerland: A Complete Guide.

1-2 weeks
Register with the Swiss Commercial Register
The next step is to submit the notarized statutes and other required documents to the Commercial Register (Handelsregister) of the canton of Basel-Stadt. This registration grants the company legal personality and allows it to operate under its official name. The registration fee is CHF 420 for corporations and limited liability companies. After submission, the company will receive a registration certificate and a unique Unternehmens-Identifikationsnummer (UID) from the Federal Statistical Office. This UID is essential for all future interactions with Swiss authorities, including tax and social security filings. The EasyGov.swiss platform simplifies this process by enabling online submissions and document management.

Set Up Tax and Social Security Compliance
After registration, the company must register with the relevant cantonal and federal authorities. This includes the cantonal compensation fund (AHV/IV), the Federal Tax Administration (FTA), and the Swiss Federal Office for Customs and Border Security. The company must also register for VAT (MWST) if its annual turnover exceeds CHF 100,000. For companies with total assets over CHF 5 million, a withholding tax declaration must be submitted within 30 days of the general meeting. The Withholding Tax Declaration Requirements provide detailed guidance on this obligation. Additionally, all companies must file annual financial statements and tax returns, with the first return due within 12 months of incorporation. The Basel Startup Guide: Launch in Switzerland's Life Sciences Hub offers tailored advice for life sciences entrepreneurs.
