As it is now widely known that car fuel expenses can be requested to adjust against the income tax from paye job. But I am wondering that whether the same applies too in a situation where a paye employee use buses/trains to go to his temporary workplace and employer isn't contributing anything.
There is no statutory requirement to update the main employer about second job. So I am wondering that can the main employer finds out that you are working elsewhere despite your main job is under normal tax code? Does HMRC reveal this information to employer? Thanks
