Reuters:

Sprint, the third-biggest U.S. mobile service provider, failed to bill customers for more than $100 million of taxes for its wireless services over seven years, according to New York Attorney General Eric Schneiderman.

Sprint’s problems continue, as it seems the company might have been giving its customers an unfair break over the past seven years.

Update: Sprint has a response:

“This complaint is without merit and Sprint categorically denies the complaint’s allegations. We have collected and paid over to New York every penny of sales taxes on mobile wireless services that we believe our customers owe under New York state law. With this lawsuit, the Attorney General’s office is claiming New York consumers, who already pay some of the highest wireless taxes in the country, should pay even more. We intend to stand up for New York consumers’ rights and fight this suit.”
