Online businesses should comply with federal import and export laws, and should also be aware of possible tax liabilities if they do business in a particular state. The U.S. Supreme Court ruled in Quill Corporation v North Dakota that merely conducting business with customers who live in a particular state was not sufficient grounds for a state to force that company to collect sales tax on its behalf. However, another Supreme Court case, Wisconsin Department of Revenue v. William Wrigley Jr., Co., stated that maintaining a "nontrivial" presence in a state does subject an online business to the requirement to collect sales tax for that state, even if its main operations are located elsewhere.

The Children's Online Privacy Protection Act (COPPA) specifically pertains to online commercial establishments that knowingly collect personal information from children younger than 13. COPPA requires such websites to post prominent notices informing parents of their right to obtain information collected about their children and prohibits collecting certain information from children younger than 13 without their parents' explicit consent. Online businesses should also inform visitors of the site's privacy policy, especially how the company plans to use information that it collects about its customers, and to give customers the ability to opt out if they so choose..
