Selling apparel containing trademarked things on them online that is imported in Trademarks, Copyrights, and Patents Posted July 15 · Report reply 3 hours ago, AZ-native said: Will I need to obtain an EIN and create a business entity (LLC) if I were to go forward, prior to the site going live? Not necessarily. An LLC is a disregarded entity for income tax purposes. You would use your own SSN and attach Schedules C and SE to your return. Nor will an LLC protect you from being sued personally for trademark infringement. 3 hours ago, AZ-native said: Would I also have to obtain a trademark license from the company in order to post them online? The best and safest route is to get consent from the manufacturer even if it means buying a license. An infringement lawsuit can put you into the poorhouse just from defense costs even if you haven't done anything wrong. If you aren't willing to do it right, don't do it.
