Council tax forms

So the council is changing its procedures or whatever, and I get a new form to fill out in order to claim council tax. This form is even more Orwellian and mind-numbing than the last. It's a full 28 pages long, and among other things, they want my flatmates' national insurance numbers and "proof of earnings" for each of them (i.e. a copy of their payslips for the last two months). They also want to know exactly how many people live in the entire building. Fsckers.
