The revenue is so desperate now because of this change in banks and building societies have left people not knowing what the situation is, and er there are millions, I'm, I'm not exaggerating there are twelve million, over two million pounds is being spent by the revenue on a new tax-back advert, sorry I did exaggerate, the idea is to remind about ten million people on all, on low income, that they could claim back tax which has been deducted from taxed savings.
