Hope someone knowledgeable can help me, dh is starting up a small internet shop, as his annual salary is more likely to eventually hit the 40% tax mark he said best to put thebusiness in my name. I work part time and also have a small internet business but earn under the threshold for my business to pay the Ni (i have like an expemption thigymabob), so my business and dh's which will be in my name will be kept entirely seperate and his will also probs stay under NI threshold - if both combined go over do i have to pay it or are they treat seperatly? Sorry im confused now and wondering do i really want it in my name. What is the 40% tax level anyway and is it just onthe bit over it? Hope you understand my post.
