Today I received my first ever letter from concentrix wanting to check my childcare costs, this to begin with confused me so I checked my award sheet from my tax credits renewal pack and it doesn't say anywhere that I get a childcare element of working tax.
Ok so I phone them and try to find out what is going on lady I spoke to says she needs the receipts from 15/16 tax year, I explain I didn't think I was getting any help towards childcare (i estimated my costs as being £40 when asked last year, this is more now as have 2 children in childcare but am managing to pay it myself). Turns out I may have been overpaid whilst on Mat leave last year (8months) as I didn't put them into childcare while of but when I phoned tax credits to inform them I was on maternity leave they said my money would stay the same regardless 
So fair enough I'll send the stuff they are asking for but out of interest I use the turn 2 us calculator to see what my money comes out as but leave my childcare costs as £0 and the end result is that my working tax credit amount matches what is on my award notice which was input with no childcare costs so I am very confused now as I don't think I receive any childcare contribution from what the calculator says? Sorry I'm really making no sense but I'm a bit hacked off!
Thanks for any answers
