In January 2012, just before leaving office, Taft published "Follow the Money", his fourth book. Research for the book was supported by two economists: Professor Melville Macmillan and Dr. Junaid Jahagir. Drawing heavily on economic data from Statistics Canada, the book challenges the notion that the Alberta government's spending on public services is far higher than other provinces. Taft shows that total Alberta corporate profits are consistently double or more the rates in the rest of Canada or the United States. In contrast, spending on public services in Alberta is in the normal range, and the government has failed to increase the value of the Heritage Trust Fund. Like its predecessors, "Follow the Money" topped local bestseller lists. The book was also shortlisted for the Alberta Book Publishers Association Trade Non-Fiction Book of the Year in 2013.
