Haven't had one in years. When I did it was a non-refundable credit and the client did not benefit from it since he was going to receive a full refund anyways. I would take a look at the quickfinder, and the US Master tax guide, to see what the credit amounts are, and if they differ for different vehicles, and then determine whether it is refundable or non-refundable. Also I think it may change with the soon-to-be passed tax legislation, if it is passed?... Maybe it'll be approximately March 15th like last year. I would definitely wait on this return, and see if the software is updated, but all of this is just my opinion.
