TUSKERDIRECT has launched an online tax calculator to check tax levels against those returned by the Inland Revenue.

It can be found at www.tuskerdirect.com. Users are then asked to complete a form and the system will calculate the current tax level and the BIK rates under the new regime from April.

It follows the news that up to 200,000 company car tax returns supplied by the Inland Revenue could be incorrect.

Tom Stephenson, joint managing director of Tuskerdirect, said: 'When we heard from Fleet News of the extent of the problem, we knew we ought to develop a solution, not just for our own customers, but also for the thousands of other company car drivers who are confused.'
