Good Afternoon. As stated on here before, took a tribunal to get pip and lcwra, now I get a letter saying I owe 5k from a previous over payment for tax credits. I'm gutted as the money I get just about covers everything.. They said I need to call before they take a large amount each month. I appealed this back in 2016 but heard nothing.. So my question is what would be a reasonable amount to offer?..
