Hi, I have recently received a revenue check and based on this have discovered have have incorrectly claimed some tax credits. I had incorrectly put in for income continuance, when I looked into it further there was relief at source so wasn’t entitled. I amended this on my forms and repaid for the amount I received. I also do not have back up for medical claims so will need to adjust this down and repay. However it looks like I will need to repay the single persons tax credit. I bought a house with my partner in 2015 but we didn’t move into it until 2017. I think I should repay 2 years but think will get charged for the four, especially with the other amendments it will look like I was falsifying information. I am terrified here. The repayment could be ten k without penalties or interest. I have no savings as I was supporting the family on my own until this month. Will revenue accept payments of 100 a month to clear this. Thanks
