To describe the extent to which the credit is being claimed, we reviewed IRS data on the claims for tax year 2010. To identify any factors that may limit credit claims and to assess how they could be addressed, we interviewed IRS officials as well as groups representing employers, tax preparers, and insurance brokers, and worked with them to assemble discussion groups on the credit. To assess how these factors could be addressed, we analyzed our interview results as well as relevant documents.
