As a result, take-up of the tax credits is very low. The main one, the Working Families Tax Credit - introduced in 1999 and due to be abolished next year - is taken up by fewer than half of the couples entitled to it. This is a record low take-up for just about any benefit. What it means is that there are millions of families who are not getting the basic help they need, because the system has just become so absurdly complicated. It's a cross between the Hampton Court maze and Spaghetti Junction.
