Hello all, this is my first time posting on here. I have been sick with worry regarding working tax credits and the new rules. I am self-employed and have been claiming WTC since July 2014. It was very helpful towards costs and I am not disputing that BUT the new sanctions were causing me anxiety. I renewed my WTC last Fri but telephoned today to withdraw the claim. The guy was very helpful and I explained that I am going back to college in Sept and will be doing a lot of unpaid placements, and, as such, my working hours and income will fall. He withdrew my new claim but said I will have to pay back the money they have been giving me since 5 April this year. No problem, I thought as much, and so I won't spend it. But now I am reading horror stories about people being charged extreme amounts in over payments and I am worried this will happen to me. I have always been above board with my claims. i.e. 2014-15 I only earned £1880, and 2015-2016 I earned £3214 (declared on the WTC claim I want to withdraw). I think I am within their £2500 limit when it comes to an increase in my income, but I am so scared. I was receiving just under £54 a week. Can anyone advise what the likely outcome will be? I am a self-employed author and so my hours were indeed long (proof as the books have been consistently coming out since early 2015). Sorry to ramble on, I have high functioning aspergers and quite bad anxiety and the people who I turn to for emotional support are not here at the moment. So this is a very worrying time. Thanks in advance.
