No VOIP services charge taxes. Commercial land-line and cell providers are required to charge taxes. This is another way Residential VOIP can save money for its users. VOIP is considered an Internet-based service, like email or web browsing. These services are not (yet) taxable. However, this benefit comes with a caveat: VOIP services aren't regulated either. So VOIP providers are not required to meet the same governmental standards as commercial land line and cell providers.
