Hey guys, I've been wanting to take my "casual" reselling up a notch so am now looking into getting a tax ID. However, after researchin this I am getting confused and am not sure which ID/license/permit I need. I know most legit wholesalers require a tax ID...but would a Sales Tax Resale Certificate Number work as well? I am in PA and am not ready to get an LLC or Inc, is this a must to get a Fed Tax ID? Do I need a business license? Anyone that is familiar with this please share what exactly I need to apply for. Also, I don't really want to use my SSN as my ID. Lastly, I am trying to operate a small home based reselling business...mainly selling online and want to get legit wholesalers to deal with me. Thanks!
