The 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 http://www.irs.gov/Businesses/Small-Businesses-&-Self-Employed/How-to-Apply-for-an-EIN for more information. Please note: This number is not the same number as your FEC committee ID number. The FEC does not issue EINs, nor may FEC staff answer questions about the rules that pertain to them or other tax law requirements.
