Legal advice on Small business taxes

I have a teaching business as a sole proprietor (I have my EIN and DBA registered with this business). Now, I want to start my second, separate and unrelated business (ecommerce) - this time an LLC. Can I get a new EIN number for my LLC or am I supposed to use the same EIN I used in my first business?

2 part question. First. Do i have to file a separate Certificate of formation for my LLC (even though i already filed a DBA)? second, can i use the same EIN number for my new LLC?

In my overzealous youth I got the bright idea to use legal zoom to create an LLC. That was as far as I got. I did receive an EIN but I never actually conducted any business activity or generated any income under it and honestly forgot about it. Now almost 10 years later I'm remembering and panicking. I did a search on the Maryland.gov Business Express site and the LLC status is forfeited in 2016, 2 years after it was created which I'm assuming happened because I never filed any annual reports. I believe there was supposed to be a $300 annual filing fee to maintain the LLC. Am I still on the hook for paying that money for the past 10 years even though the status is forfeited? Can I terminate it without paying those fees? What would happen if I continue to leave it as forfeited with no business was conducted, no assets under it and no income generated?

We each own 50% of a corporation registered in Texas. I loaned the business from my personal funds and partner owes his part of the debt. He wants to shut down the business and start another one on his own. Is there any way he can pull this off legally and how can I hold him accountable? Secondly, although we own equal shares of the company my partner is more involved in the day to day business activities . In the 5 years we’ve been in business we’ve accumulated lots of clients that are loyal to my partner. He intends to open his own company and then have our clients follow him. In essence he is reopening our business under a different name and he will have sole ownership. Is there any way to prevent him from serving these clients?

I have a general-purpose LLC that I use. I'm often snatching up domain names I find available, hoping that I can eventually receive an offer on them. Do these qualify as a business expense?

I own a LLC that my Dad started. I joined as a member years ago, and now he has retired, so I own the now single member LLC. I want to partner with a Sole Proprietor by trading shares of the LLC for his assets, thus making him a member of the LLC and "buying" his business, which we will operate together. He has a loan for his building and equipment that is non-transferable. We weren't planning on exchanging cash in the deal, and I don't have enough cash on hand to pay off his loan. Taking out a new loan to pay off his existing loan would result in the LLC paying a much higher interest rate than his current loan. The building that he operates his business in is tied to his current loan. What can be done?

Just want clarification - register the name - if so, where? How else can I protect myself and company?

My business partner and I co-own properties. I would like to convert our investment property to LLC

I have a question about the following scenario: 1. A Wyoming Corporation exists, formed in Wyoming. Example name: ABC WY Corp Inc. 2. ABC Wy Corp Inc establishes an LLC in New York. It is called DEF NY, LLC. 3. The sole owner of the LLC is ABC WY Corp Inc. BUT the LLC is registered in New York, has physical nexus in New York, and operates in New York (for example, printing and selling/shipping books from New York) How does the income tax work? For example, if the company has 100K gross revenue, and 20K profit at the end of the year: Does the income tax flow through to the Wyoming Corp so that it pays 21% Federal Income tax and 0% Wyoming State Tax? Or does the income get taxed by New York? Note: I am not referring to other New York taxes it would pay such as franchise tax, sales tax, etc. I'm only asking about income taxes.
