This technical paper describes the methods by which the derived annual income variables are constructed as of Release 12 of the HILDA Survey, which contains data from Waves 1 to 12 (2001 to 2012). In particular, it explains how income components are aggregated and certain government benefits are estimated to produce total income measures, and how taxes are estimated to produce post-tax (disposable) income measures. The methods used to impute missing values, and the extent of missing values, are not discussed in this paper; these are described in Hayes and Watson (2009) and Summerfield et al. (2013).
