Assuming stock is property under the code, a person transferring appreciated property in exchange for the corporations stock (provided they meet the 80% control rule) does not recognize a gain on the transaction. The "gain" is deferred and will be recognized when the stock is sold.
Your basis in the stock will be $60. Thus, if you sell the stock in the future you will pay taxes on any gain over $60. Furthermore, the corporation will also have $60 basis in the stock it obtained.
The nature of the taxes will depend on the holding period, i.e LTCG or STCG.
I do not deal with this extensively and my corporate tax references are in the garage, in a box, collecting dust, so this may not be 100% accurate.
