What are the most significant credits claimed by individual taxpayers? How do the credits claimed differ by income class? To answer these questions, go to the IRS Tax Statistics page (www.irs.gov/uac/tax-stats) and download the Microsoft Excel spreadsheet that documents tax liability, tax credits, and tax payments. You can find this in the Individual Income Tax Return (Form 1040) Statistics section of the site; click on the “by Size of Adjusted Gross Income” link. Evaluate the credits claimed (both nonrefundable and refundable) by size of AGI. Group the data into the following AGI classes: $25,000 or less; $25,000 to $50,000; $50,000 to $100,000; $100,000 to $500,000; $500,000 or more. E-mail the spreadsheet to your instructor along with a brief summary of your findings.
