The Internal Revenue Service (IRS) requires political committees to obtain a tax ID number, formally referred to as an employer identification number (EIN). Your committee will need this number to open a bank account. The preferred and quickest way to obtain your committee's EIN is via the IRS's website. Visit https://www.irs.gov/businesses/small-businesses-self-employed/how-to-apply-for-an-ein for more information. Please note: The FEC does not issue EINs, nor may FEC staff answer questions about the rules that pertain to them or other tax law requirements.
