I'm a freelance web developer and file taxes on income I receive from my freelance projects on my personal tax returns. I requested and received an EIN number from the IRS so that if I needed to give out my W9 to any clients, I don't have to share my SSN for security reasons.
One client's CPA that I sent my W9 to is saying that since I provided an EIN on my W9, I need to provide the associated company name to them to properly file on their end. However, I never set up a company name associated with my EIN since these are just freelance projects on the side.
I reviewed the letter from the IRS when they provided the EIN number and there is no mention of a company name. The letter does mention that "your name control associated with this EIN is <first 4 letters of my last name>".
From all my research so far, all I can find is why and who can get an EIN, but it's unclear to me if I do in fact need a company name (such as an LLC) associated with it. I thought my name and EIN would suffice since I don't have an LLC and no employees.
