Thank you for giving me the opportunity to assist you. I will give the best answer that I can with the information provided.
There are no taxes for the recipient of a gift. It is the donor's responsibility to account for amounts for that are given in case there are any gift tax consequences. He is allowed to give you $13,000 per year with no gift tax consequences. However, the fact that he is pre-dating one check and did not actually make it available to you until 2011 is bending the rules...but that is his issue, not yours.
Please let me know if you need additional assistance.
