The LLC is typically the best choice for smaller entities. The LLC structure provides a great deal of ownership flexibility in that an LLC may have any number of Members (owners) including non-US citizens and subsidiary companies. LLCs are also able to distribute several different classes of stock or ownership interest. However, their owners are typically required to pay a self-employment tax.
A grocery store goes out of business prior to January 1st but equipment such as freezer boxes and store shelving remains in the building on that date. In this case, such items would still be taxable and must be reported even though the business was closed on the Lien Date. That is because in this case, the equipment could not revert to or be used as "Household Furnishings or Personal Effects".
