Hoping someone out there can answer that question. I`m a sole proprietor of a small business, and filed in 2006. I make jewelery and tshirts and filed as such. I`ve opened a bank account, but never really needed to deposit money. But now I would like to use my small business for all my income (I`m also a virtual assistant) and would like to file it under the company. Is it too late to get an EIN?
