If this is your FIRST home purchase AND if you are a U.S. citizen or resident alien, you qualify for the $8,000 First Time Home Buyer's Credit, which you can claim on your 2009 tax return or you can amend your 2008 return.
I recommend claiming the credit on the 2009 return, because the IRS is back-logged on 2008 amendments, so, quite frankly, you will probably get the refund faster on the 2009 return.
If your friend has never done the NJ tax return, then you should get professional help, as the NJ return is one of the more complicated state returns to prepare.
