I have been with potential buyers recently who are eligible for the tax credit and have asked this question. The first question is understandable but the second question I was concerned about. They were under the impression that since it is 2010 they had to file for the tax credit on their 2010 taxes (which makes since). This is not the case at all. If you are eligible for the tax credit, and you close on a new home before June 30, 2010 you can file for this tax credit on your 2009 taxes.
