Acro is right, at least that works here in Canada. "Selling" domains to your corp is a legal trade between 2 distinct legal entities. You could sell the for however much you like - if you want to get $$ out of your corp into your hands, sell high. If you want to leave the corp funding out of it, sell for a dollar. Its just a buyer and seller agreeing on what is "fair value".
My corp just got a great deal on 2 new pc's - cost a buck
