Thanks for your help so far Andrew. I have a last question (hopefully):
Questions in C on form page 3
Do I have to answer most of the blocks on that page. They seem to repeat in some occasions. So to give you the details, I am occupying a flat of about 70 Msq free of charge. As I said I work on my laptop, I don't need a desk or a particular room, so you suggested to give them 4 Msq.
Do I have to answer questions 1,2,6,7,11,14,15 or just 20 and 21
Thanks very much Andrews. I have emailed the tax office 2 weeks ago with these questions and of course no reply yet, I phoned and I am on hold for ages, and time is running out.
