A new tax on broadband use could be made law before the next election, according to Minister for Digital Britain Stephen Timms.
It would apply to everyone with a fixed line telephone and could raise up to £175 million a year.
Speaking at a debate in London, Mr Timms said the tax will be presented to parliament as part of the Finance Bill.
He said: "We want to make high speed networks nationally available. The next-generation fund will help that and we will legislate for it this side of a general election."
