Nunes has long been a proponent of a consumption tax model and has been influenced by David Bradford. In 2016, he introduced the American Business Competitiveness Act (H.R. 4377), known as the ABC Act, a "cash-flow tax plan" featuring full expensing and a reduction of the highest rate for federal corporate income tax rate to 25%. Nunes's proposal was influential among House Republicans, and had similarities to the House Republican tax plan introduced by Speaker Paul Ryan and Ways and Means Committee Chairman Kevin Brady in June 2016. Conservative economist Douglas Holtz-Eakin said Nunes had "a tremendous impact on the debate" for a non-chairman.
