Recent tax law changes give homebuyers and homeowners new ways to save on their 2008 taxes. First-time buyers who purchase a house any time from April 9, 2008, through June 30, 2009, may be able to claim a tax credit of 10% of the purchase price up to a maximum $7,500. And you don’t have to rush to close the deal before December 31. You can claim the credit on your 2008 taxes even if you buy a home during the first half of 2009.
