I started my business as a corp. in the middle of 2013. My wife and I filed a joint personal return and a business return also. I need a copy of the business return so I can buy a house. They want a return with the pages not a transcript. How do get that?

You need to complete form 4506 and mail it to the IRS. The form is avaiable here: http://www.irs.gov/pub/irs-pdf/f4506.pdf

The cost for a copy of the return is $50, and may take 60 days to process. This is one reason why you should print out and keep a copy of your tax return. On the off chance that you paid a 3rd-party preparer to do your taxes last year, I suggest you check with them to see about gettng a copy from their records.
