If your LLC, corporation, partnership, or nonprofit corporation conducts business activities in more than one state, you might need to form your business in one state and then file for foreign qualification in other states where your business is active.
The state where you form your business will consider your business to be domestic, while every other state will view your business as foreign. Foreign qualification notifies the state that a foreign business is active there.
To foreign qualify, file a Certificate of Authority with the state. Many states also require a Certificate of Good Standing from your state of formation. Each state charges a filing fee, but the amount varies by state and business structure.
