Baffled...
If persons A, B and C wrote a book, and the book is sold online, the profits from the book go to person A, because you can only have them sent to one person...
Person A then keeps their 3rd, and sends the other 2/3rds to person B who then keeps their bit and sends the last 3rd to person C (there are reasons it happens like this)...
Is person A liable for all of the tax on the whole amount?
Persons B and C are declaring their share and paying tax on that if it pushes them over the tax threshold.
All are self employed one is also retired, no ones on any means tested benefits.
