OK, for those who can't see how someone earning £35k might need tax credits, here's a little example.
Single parent of 2 pre-school children, works full time, earns £35k. After tax, NI and student loan deductions, she brings home c.£2,100pm. Lovely.
BUT, what is she to do with those pesky pre-school children while she goes to work? Tie them to a tree outside her office? Leave them at home alone? I imagine both options would be frowned upon by social services. So, she has to pay for childcare. Where I live, in a relatively affordable area of the country, a full time nursery place would cost £170 per week, per child.
So, our woman taking home the lovely £2,100pm now has to pay just under £1500pm of that to the nursery. Leaving £600 to pay for everything else. And she doesn't need tax credits?
Under the current system, she's get approx £150pm in child benefit and £800pm in tax credits, leaving her with a total of £1550pm as her actual income after childcare.
Yes, it costs the tax payer a lot of money for those years when her children need childcare. But she also pays quite a bit of tax and national insurance, and will hopefully continue to do so once the children have grown up.
