In the United States, every state with a sales tax law has a use tax component in that law applying to purchases from out-of-state mail order, catalog and e-commerce vendors, a category also known as "remote sales". As e-commerce sales have grown in recent years, noncompliance with use tax has had a growing impact on state revenues. The Congressional Budget Office estimated that uncollected use taxes on remote sales in 2003 could be as high as $20.4 billion. Uncollected use tax on remote sales was projected to run as high as $54.8 billion for 2011.
