Hello, I was recently forced into unemployment. I currently receive child tax credit for my daughter and jobseekers allowance. I intend to go self employed as I start work for 12 hours a week next week as a counsellor, I am paid as a consultant. I may only invoice for 12 hours but will probably put in about 20 a week. My question is if I tell tax credits that I do 20 hours a week will I receive working tax credit? I can only really prove that I do 12 but know I will put in alot more. I also know that as a single dad I need to work 16 hours a week to claim wtc. How much proof do they need? I'm worried.
