Hello, I will be happy to assist you. After you receive your answer, please let me know if you need clarification. If not, your accept would be appreciated (and is necessary to compensate me as an expert, even if you are a monthly subscriber - although monthly subscribers will not be charged an additional fee).
A corporation can operate a d/b/a under its umbrella as long as it's not prohibited by the articles of incorporation or the bylaws of the corporation. The corporation, not you, would register the d/b/a, and the d/b/a would not be a sole proprietorship, it would simply be taxed as part of the corporation, since it is the corporation for all legal purposes. Thus, it will be taxed as a c-corporation or an s-corporation depending on how the corporation is taxed.
If you want to operate the d/b/a as a sole proprietorship, you would have to register the d/b/a in your name, individually and it would not be part of the corporation. In that case, you would not have the limited liability features of the corporation.
Since d/b/a must be registered in your state, I doubt the bank will allow you to make a deposit into the corporate account until you can show that the d/b/a is registered to the corporation.
I believe I have answered your question. As noted above, please let me know if you need clarification, and if not your accept would be appreciated. Additionally, if you post a new question for me in another thread, please begin the question with "To TMcJD...." This will ensure that only I answer the question.
