My client's S corporation distributed more than her stock basis this year. How is the excess taxed, and what goes on Form 7203?

S Corporation Distribution Above Stock Basis

Short Answer

If your client’s non-dividend S corporation distribution exceeds her stock basis, the excess is generally taxed as capital gain from the sale or exchange of property under IRC § 1368(b)(2). The gain is usually reported on Form 8949 and Schedule D, and the holding period of the S corporation stock determines whether it is long-term or short-term capital gain.

On Form 7203, the distribution is entered in Part I, line 6. If line 6 exceeds line 5, the excess is not allowed to reduce basis below zero; instead, the excess is reported as capital gain on Form 8949 and Schedule D, and Form 7203 line 7 stock basis after distributions is zero. 11
