S1285

I just got a letter from the Tax Credits with a S1285 attached. I am a lady of 61 who lives with a male friend. I know how the locals perceive us and I am fed up of saying he's not my partner. We are friends and have had no romatic or financial arrangement since 2001. Before that we were partners for a couple of years. It looks like the want to class us as a couple which we are not in any sense of the word and the wording on the letter is very scary. Can anyone help please.

The wording is deliberately scary.

Unfortunately we do not give tax advice.
There must be an appeals process. Perhaps you could start here
