Doing Business As: denotes a business name used by a person or entity that is different from the person's or entity's true name. DBAs are not separate entities and do not shield the person or entity who uses the DBA as a business name from liability for debts or lawsuits. Filing requirements vary and are not permitted for some types of businesses or professional practices. See also Delaware corporation, Delaware statutory trust, Nevada corporation, and Massachusetts business trust.
Since limited liability companies can be a pass-through entity, owners are taxed on their personal income. S-Corp shareholders are taxed personally. The S-Corp, however, is not. C-Corp income is taxed at the corporate level first, then again at the personal level. This is called "double taxation." Non-Profits are only taxed once and can write off most of their expenses. Sole Proprietors are taxed only on their personal tax return.
Your name must be unique, and not deceptively similar, to any other trademarked name or business. It is also required that your name not be used to intentionally misrepresent the products or services you offer. For LLCs, nearly all states will also require you to add a signifier of your limited liability status, such as "LLC" or "L.L.C." to the end of your company's name. You may be able to operate under a name other than your formal LLC name by applying for and using a dba.
Limited liability companies can claim deductions but not tax-exempt status. S-Corps can claim deductions but not tax-exempt status. C-Corporations are not tax-exempt entities Not only are donations to Non-Profits tax-exempt, but NPOs can themselves apply for tax-exempt status. Sole Proprietorships are the least official business entity and cannot claim tax exemption.
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.
