The era of tax-free email, Internet shopping and broadband connections could end this fall, if recent proposals in the U.S. Congress prove successful.

State and local governments this week resumed a push to lobby Congress for far-reaching changes on two different fronts: gaining the ability to impose sales taxes on Net shopping, and being able to levy new monthly taxes on DSL and other connections. One senator is even predicting taxes on email.

At the moment, states and municipalities are frequently barred by federal law from collecting both access and sales taxes. But they’re hoping that their new lobbying effort, coordinated by groups including the National Governors Association, will pay off by permitting them to collect billions of dollars in new revenue by next year.
