I really think you would be better speaking with US corporate Attorney firm about it. Essentially no difference between Wyoming and Nevada, except for filing fees and charging orders against a corporation (to do with when you are sued, how people can access compensation if the case is found against you).
The following notes (in blue) are from an information package from Corporate Direct, a law firm in the states, and from my email conversation with my contact there.
When forming LLCs in Nevada and Wyoming the protections offered by state law are very similar. Garrett feels the these two states offer the strongest charging order protection for LLCs. When forming a corporation the main difference is when there is more than one shareholder. In this instance Nevada would be better as Nevada is the only state that includes charging order protection for corporation, but there has to be more than one shareholder.
Why would a person form an entity in one state and then qualify in another state?
Many people will form an entity in Nevada for the privacy and asset protection benefits and then qualify to do business in their home state, California, for example. The qualification process involves having our Nevada office, for example, provide a certificate of good standing for the Nevada corporation and then file with the California Secretary of State for permission for the Nevada corporation to do business in California. It is not an overly complicated process, but it is an important process to ensure that your entity's limited liability protection follows you into the states in which you actively conduct business. Corporate Direct provides this qualification service at an affordable price.
Why incorporate in Nevada?
For many reasons, Nevada is one of the best places in the United States to incorporate. Nevada has excellent privacy laws, minimal reporting requirements, close proximity to the major California market, good road and air transportation connections and a business-related infrastructure that continues to attract major businesses such as Starbucks, Barnes & Noble and amazon.com.
Privacy: Nevada does not share shareholder information with the IRS. In Nevada shareholders are not a matter of public record which allows for maximum anonymity and privacy. In addition, nominee officers and directors can be provided to further enhance privacy.
Asset Protection: Nevada's asset protection laws are viable and the corporate veil remains one of the strongest in the country.
Corporate Flexibility: Directors, officers and shareholders do not have to live in or hold meetings in Nevada. Telephone meetings are permitted. One person may hold all director and officer positions, and directors/officers do not have to be stockholders. Corporate bylaws can be made or expediently changed by Directors. Nevada law also allows for various classes of stock and debt, securities and voting restrictions, rights and preferences to be included in the articles and bylaws. These and other favorable features of Nevada corporate law provide for great corporate flexibility and ease of maintenance.
Favorable Capitalization: No minimum capital number is required to incorporate. Shares may be issued not only for money or assets invested, but also for personal services, leases and options granted, and personal property. In addition, a Nevada company may purchase, sell, hold or transfer shares of its own stock.
Why incorporate in Wyoming?
Wyoming is one of the fastest-growing states for low-cost, low-maintenance and no state tax incorporations. Why? Because Wyoming has actively sought to make it’s corporate law and business tax structure friendly and attractive to out of state companies looking for the best all-around tax and legal structure.
Privacy:Wyoming requires officer and director information only. No information on shareholders is collected or shared with the IRS. Nominee officers and directors can be used to enhance privacy.
Asset Protection:Wyoming has strong asset protection law – perhaps the strongest in the United States today.
Formation Costs:Wyoming is inexpensive compared to other states, even Nevada. Minimum filing fees add up to maximum savings for you.
Maintenance Costs:Wyoming has one of the lowest annual fee structures in the United States. Because the Wyoming annual fees are based on assets or employees physically located in Wyoming, you could pay as little as $50 per year to maintain your non-resident Wyoming entity.
Low Capitalization: Wyoming has no minimum capitalization requirements. Some states, such as Texas insist that you put at least $1,000 into your entity on formation!
Corporate Flexibility: Directors, officers and shareholders do not have to live in or hold meetings in Wyoming. Telephone meetings are permitted. One person may hold all director and officer positions and directors and officers do not have to be stockholders.
