SPMFEDTAXAC measures a family's total tax liability after all tax credits are deducted. Tax credits include the earned income tax credit and the child tax credit. This variable is used in the construction of the Supplemental Poverty Measure (SPM) and is measured for the entire SPM family unit.
In 2014, the Census Bureau updated SPMFEDTAXAC values for CPS ASEC 2012, 2011 and 2010. Extracts made on IPUMS-CPS before April 15th, 2014 have the outdated values for SPMFEDTAXAC.
Tax liability before credits is reported in SPMFEDTAXBC.
Amounts for SPMFEDTAXAC are expressed in dollars of the given year, rather than in constant dollars adjusted for inflation. Users can adjust for inflation using Consumer Price Index adjustment factors.
For more information on calculation of the SPM, see the Census Bureau's "The Research Supplemental Poverty Measure" report.
