A new National Institute for Health Care Reform analysis compares the Cadillac tax to capping the tax exclusion on employer health benefits. The analysis found only modest differences in progressivity—or the degree to which higher-income people bear a higher tax burden—between the Cadillac tax and capping the tax exclusion, primarily because employers are likely to avoid a substantial portion of the taxes by restructuring health benefits, particularly in response to the Cadillac tax.
