Formation Formalities & How Your US Company Is Formed

Part of the guide US company formation: the guide for your real business in America

Forming a C Corporation, LLC or Limited Partnership in the USA is generally a quick process. We take care of all the documents and filings you need, and we complete the formation itself within one week. The rest of the process, every step included, takes no more than 4 weeks in total. Here is how it works:

  1. To form your US company, you choose the legal structure you want (C Corporation, LLC or Limited Partnership) in the US state of your choice and simply book the matching product on our website.
  2. To book, add the product to your cart and proceed to checkout.
  3. We then email you an online form where you enter all the information we need to form your US company.
  4. Once you have completed the form, send it back to us together with proof of identity.
  5. If we have any questions, we will get in touch with you.
  6. Next, the attorneys on the firm's team draft and file all the documents required to form your US C Corporation, LLC or Limited Partnership. We charge state fees at cost. How long formation takes depends on the authority in the relevant state. We then provide a local Registered Agent in your company's home state.
  7. Once your company is formed, we email you the formation documents.
  8. After that, we register your US company with the IRS and open a US business bank account and a euro account for the company.
  9. Finally, we email you all your company information, your US tax number and the details of your US company's bank accounts.

Once formation is complete, we start the ongoing support of your US company. This includes, for example, ongoing bookkeeping, payroll, annual financial statements and more. We fine-tune how we work together and get in touch with you after your company has been formed to go through all the details.

If you have booked any additional services, we handle these during the process once your US company has been formed. Any confirmations or additional information are then sent to you digitally along with your other documents. For a thorough introduction to the topic, read our guide to forming a company in the USA.
