I rang tax credits to inform them of my 2nd child being awarded dla. The man said he'd backdate everything and I'd get at least £500 backdated money. My award letter came through - I've been given £395. I rang up today to query it and was told they've kept £310 of my award as my whole tax credit amount is quite large (dh didn't earn much last year as he's newly self employed), so they're keeping the £310 until the end of the year when we reapply. If it turns out dh figures were correct then they'll give me the money back then. If his figures were wrong then they'll keep the money and sort out how much I will pay them back?!? Surely they can't do this? Dh has an accountant so figures were right. I'm just 
as to how and why they chose this amount. I've since had 3rd child awarded DLA and they haven't kept any further money apparently. Although her backdated money isn't right either??
