My CPA applied EIN as third party designee, any problem?

The Third Party designee on Form SS-4 only receives the ID number and can answer questions about the form on behalf of the taxpayer. This does not make the CPA a responsible party. The CPA should not have used their Social Security number. You should have obtained a taxpayer ID number and put that on the application. It sounds like the CPA was being more than a third party designee. CPA's should also not be setting up corporations since this is a legal process that should be done by a lawyer. For a corporation, the responsible party should be the principal officer of the corporation. The CPA did not have the authority to use his social security number or apply for this tax identification number unless he held this position. Also, applicants that are not in the United States cannot apply for a tax identification number online. It is a federal crime to obtain a tax ID number under false pretenses or to use an incorrect social security number to obtain an ID number. You should see a local attorney to correct this situation.
