Single-Owner Disregarded Entities Treated As Separate For Excise Tax and Reporting Purposes

"After December 31, 2007, qualified subchapter S subsidiaries (QSubs) and eligible single-owner disregarded entities are treated as separate entities for excise tax and reporting purposes. QSubs and eligible single-owner disregarded entities must pay and report excise taxes (other than IRS Nos. 31, 51, and 117), register for excise tax activities, and claim any refunds, credits, and payments under the entity’s employer identification number (EIN). These actions cannot take place under the owner’s taxpayer identification number (TIN)."
