I think this is the right place to post as it's more about money than work.
DP works in construction on a self employed basis. This is through the Construction Industry Scheme (CIS) which means all his income is taxed at 20% before he gets it. He then submits a tax return each year and generally gets a refund. I think he is classed as a subcontractor, so the building company pays a secondary company to supply bricklayers and labourers. This secondary company then pays DP on a set date each month and sends him a payslip. So basically he is treated as though he is employed but with none of the benefits of annual leave and sick pay. I believe this is a bit of a contentious issue within the industry.
Anyway I am trying to apply for a joint current account online and have to put if he is employed or self employed (sole trader, director or one other unrelated category). Self employed is correct, but it then asks about your business name, company number etc and it's all a bit confusing because he has none of those things. Would I put self employed as a sole trader? That's not really eight either. Employed makes more sense as he just gets a set wage like anyone else but would not be technically correct. I'll give them a ring or just apply in person rather than online but thought someone here might know.
