This message can occur if the tax credit on the clients dividend income has been overridden and is not 10%, this can also occur if the tax credit on dividend income is shown as zero. Users are required to contact HMRC who can provide details of an alternative section of the Tax Return where this income can be entered in order to file the Tax Return online. If the tax credit is exactly 10% then send an extract to support@iris.co.uk with a copy of the rejection error for further investigation.
