Forming a Swiss LLC, also known as a limited liability company, can be a complex process. However, by following a checklist of steps, you can ensure that all the necessary steps are completed and that your LLC is formed correctly. Here is a complete checklist for forming a Swiss LLC:

1. Choose a name for your LLC: Before you can form your LLC, you must choose a unique name that meets the requirements of Swiss law. Your LLC’s name must be distinguishable from the names of other companies and must not contain any restricted words.
2. Obtain a Business Identification Number (UID): Before you can register your LLC, you must obtain a Business Identification Number (UID) from the Swiss Federal Tax Administration (FTA). This number is required for all business entities in Switzerland and must be included in all official documents.
3. Create an LLC agreement: An LLC agreement is a legal document that outlines the rights and responsibilities of the members of the LLC. It should include details such as the percentage of ownership, the management structure, and the distribution of profits.
4. Register the LLC: To register your LLC, you must submit a registration form, the LLC agreement, and other required documents to the Commercial Register of the canton where your LLC will be located. You will also need to pay a registration fee.
5. Obtain a VAT number: If your LLC is engaged in taxable activities, you will need to obtain a Value Added Tax (VAT) number from the Swiss Federal Tax Administration (FTA).
6. Open a bank account: To conduct business and manage finances, your LLC will need a bank account. You will need to provide the bank with the necessary documents, such as the LLC agreement and the Business Identification Number (UID).
7. Obtain any necessary licenses and permits: Depending on the type of business your LLC will be engaged in, you may need to obtain licenses and permits from the cantonal or local authorities.
8. Comply with ongoing requirements: Once your LLC is formed, you will need to comply with ongoing requirements such as filing annual financial statements and tax returns, holding annual general meetings, and keeping accurate records of all transactions.

By following this checklist, you can ensure that all the necessary steps are completed and that your LLC is formed correctly. However, it is important to note that the specifics of the Swiss LLC formation process may vary depending on the canton where you will be forming the LLC, so it’s important to consult with a professional that is familiar with the Swiss corporate law in order to ensure compliance with all the local requirements.
