I'm staying out of the political discussions but I'll just add my experience. When I retired from my day job in pharma, I set up a consulting practice. You can get a business ID from IRS for free and I only had to file papers with the State of Maryland for my Limited Liability Corporation (LLC). IIRC that cost $200 or so. I had to file a yearly corporate tax statement with the State that outlined equipment and supply purchases and depreciation and disposal of equipment. that took all of ten minutes to do. I did not have to file separate tax returns for the LLC, it all went into the personal tax filing for both the US and Maryland. Everything was pretty easy and expenses on a yearly basis, minimal.
It should be pointed out that although the LLC status is a federal status, it is up to the states on how one can and how it will cost to register as one. In PA, like in Maryland, it is very easy. I think I paid a one time $125 filing fee. Also, since I run my LLC like a sole proprietor, it is operated like a pass through business with no need for payroll (for myself) or the need to pay corporate taxes.
Other states make it harder and more expensive.
Last, unless you are operating your LLC like a corporation and/or maintain separate bank accounts where you only us the business bank account, and any credit cards, for business purchases only, your business's separation from your person would be easy to argue against in court of you were sued. So, if you opened an LLC to keep your business assets separate from your personal assets, for liability reasons, make sure you do not use your business account to cover personal expenses.
