hi gmcdowell - Like all tax credits, you will need to work with your accountant to make sure you follow the rules. There are a lot of rules for documentation of employee wages, and other developmental expenses. Meeting with the accountant prior to starting your research will help in the long run. The tax credit can be applied toward research on new products, enhanced processes, redesigned facilities, etc.
On irs.gov (http://www.irs.gov/businesses/article/0,,id=156352,00.html) the research tax credit is claimed on IRS Form 6765. Form 6765 requires the taxpayer to allocate QREs among wages, supplies, and contract research expenses.
One online attorney firm indicated that this tax credit is one that has high IRS scrutiny and the greatest compliance risk. So again, work with your accountant.
Hope that helps.
