Jollydiane - I see where you are coming from, but surely you can understand the basic principle that some people will work full time, and still be getting more back in tax credits/housing benefit than they are paying in taxes, and if you took that away from them, they would not survive. And I mean that in the most basic fashion, they would not have a roof over their head, not even a single room. Even though they work FT.
You don't abolish something that important to a huge amount of people because it's inefficient - you make it work efficiently!
I understand about the estimates, but if you're on a variable income, that's pretty much imossible to do with any degree of accuracy. At the moment, anything I could earn wouldn't make the slightest bit of difference to our TC's, because I think the limit where they start to 'drop' the TC's is something like £25K? Not certain on that, but even if I worked PT for min wage, say 16 hrs a week, we'd only be getting round about £21,500 - £22K pa household income anyway. So it would just be extra on top of what we scrape by on atm.
I reiterate though, even with DP working FT, and me working PT, our household income without TC's/HB would be £21,500 - £22,000 pa. Yeah, we can rent a house to fit 5 (soon to be 6) in our town and pay for food and utilities out of that. Not.
