Checkoff

A checkoff is a bookkeeping mechanism which provides for regular payment of an obligation such as union dues. The same term is used to refer to a tax on sales of agricultural goods that finance a generic commodity marketing program; one example is the commodity checkoff programs mandated by the United States Department of Agriculture to promote sales of milk, beef, soybeans, or sorghum. Some US states offer income tax checkoffs to contribute voluntarily to various state programs.
