To answer your questions, yes, you need to register your business name with your state agency that registers them. You can use your SS# for tax reporting purposes if you are a sole proprietorship. Your bank, however, may require you to obtain an EIN from the IRS. The process is quick and easy and you can get the number by phone, fax, or mail by submitting form SS-4. You can't have both a personal and a business bank account with the same identifying number, hence the need for an EIN. You will need to obtain a sales tax permit, also called a reseller's permit, from your state tax or revenue department. The permit will contain a number that you will use when remitting the taxes you collect. Be sure to keep accurate records of your purchase of materials and your sales. To avoid problems, you should have a separate bank account for the business
