I am a bit stuck here! My husband started his new job in August, and it calculated his estimated income for the rest of the tax year by how much he was getting an hour. Now he has been made permanent, he is getting less per hour but he does a lot of over time which is way more than double. At the moment, it says estimated income is 13k for the remaining tax year but he is going to be earning far more than that due to all the overtime! Shall I now update tax credits and put estimated income? Or leave it? He still works in the same place and contracted to the same hours, plus overtime here and there.
