I find the question a little confusing. If I am following, the sub-s owns the LLC. The LLC has elected to be taxed as a corporation. I am assuming it is taxed as an s-corporation since a k1 was issued. In my experience, most owners of entities taxed as s-corps pay taxes on the amount reported on the k-1, and any amounts received are usually distributions rather than dividends. If they are dividends, they should be reported on a 1099-DIV and taxed as dividends. If they are distributions, they may not be taxable at all since tax on the profits earned was paid based on the k-1 at the time the profit was earned by the LLC.
