A value-added tax (VAT) is a consumption tax collected incrementally at each stage of production and distribution, with businesses crediting tax paid on inputs. Most OECD countries rely on a VAT for a large share of federal revenue; the U.S. is the major exception, relying instead on income and payroll taxes.
Proposals to add a VAT in the United States have come from economists across the political spectrum. Some pair it with cuts to income or payroll taxes; others use it to fund expanded benefits or to reduce deficits. Variants include broad-based VATs, narrower goods-and-services taxes, and "border-adjusted" designs.
Critics worry a VAT is regressive without offsets, hard to remove once enacted, and risks layering on top of existing taxes rather than replacing them. Supporters cite its efficiency, breadth, and ability to raise large revenues with relatively low economic distortion.
