I think he'll have to pay some council tax as explained here. citizensadvice.org.uk/benefits/help-if-on-a-low-income/help-with-your-council-tax-council-tax-reduction/how-your-council-tax-reduction-is-worked-out/council-tax-reduction-non-dependant-deductions-for-pensioners/ My issue now is that I'm unsure what I'll face when I do submit my change of circumstance. I think I should just come clean and also include when I stopped receiving job seekers allowance, but it looks very bad since this is all 5 years later than I should have informed them.

Since leaving college I was on and off the dole for several years and didn't work in that time. I live with my Dad who owns the house and doesn't pay any council tax due to him being a pensioner and little savings. Then for a couple of years I came off the dole but did some chores for my grandmother to give my Dad some money for food, etc. Then last year I registered as self-employed and have started making a modest income. I wasn't aware at the time but when I stopped claiming dole I should have informed the council then, so my Dad should have had to start paying council tax. When I first registered as self-employed I wasn't sure if I would have to go back on the dole so initially I didn't inform the council of change of circumstance, and then just forgot about it until now. The council seem to have forgotten about me as in all this time I've never heard from them. I was planning on sending the council a change of circumstance using their online form saying that I started work last year when I registered as self employed. Should I mention that I came off the dole a couple of years prior? I have the money to pay for back dated council tax, but I'm worried about if my Dad might at worst get hit with a benefit fraud arrest. What sort of trouble can I expect when I send the change of circumstance form off? Any other advice?

Thanks for the advice. I think I've got everything now.

I moved back into my parent's house at the start of this year which was also when I registered as self-employed. I currently haven't been paying any council tax since I assume I have to let the council know I've moved in. My Dad doesn't have to pay any council tax. I have the money to pay for it but what sort of trouble can I expect to be in when I let the council know about this? Also I've so far earned around £8k this year so I think I may be able to benefit from working tax credits. Am I allowed to back date this benefit to the start of the year from when I registered as self-employed? However, I also have £10k in savings so I don't know how this will effect the benefit. Any help appreciated.
