The Prime Minister is issuing tax cuts to middle-income earners, with big businesses at the heart of his bid to win back voters.

Malcolm Turnbull will be in Toowoomba today delivering his first major speech of the year on his government attempting to cut taxes of major businesses, cutting company taxes to 21 percent and a coalition push for personal tax cuts.

This is a clear sign Mr Turnbull has his sights on the next Federal election which is set to be in the next 12 months.
