Versatile Tax Status One of the most advantageous aspects of the LLC is that it has the ability to choose how it is treated as a taxable entity. According to the IRS an LLC is, by default, federally taxed as a partnership (in the case of a multi-member LLC) or as a sole proprietor (in the case of a single member LLC). The LLC, however, may elect to be taxed as a C- or S-corporation at any time the members so choose.
If you received a Notice to File a Business Property Statement from the Assessor and your business is no longer in operation, you are still required to file the Business Property Statement. You should also include a note on the Business Property Statement indicating that the business has closed, so the Assessor does not continue to assess the property.
On the other hand, if you are not responsible for its tax, then you should declare the equipment in Part III of the Business Property Statement (Equipment belonging to others). Where equipment is declared in Part III of the Business Property Statement, the Assessor will also send a Notice to File to the person reported as the equipment's actual owner.
