NASHVILLE (AP) — Comcast is suing the state of Tennessee to recoup $17.1 million paid in taxes, claiming the state miscalculated what the company owed for its video and internet services.

Comcast and its affiliates sued state Revenue Commissioner David Gerregano last week in Davidson County Chancery Court.

The lawsuit claims Comcast paid $17.1 million extra in franchise and excise taxes, plus interest, for 2012 through 2015 due to a state audit.

Comcast says the state wrongly counted its tax bill because the company performed more earnings-producing activities for internet and video services outside of Tennessee than inside, which would change the tax formula. The company also claims the state's tax assessment wasn't based on Comcast's actual books and records.

A spokeswoman for Tennessee's attorney general didn't respond to a request for comment.
