Client work as self employer (sub-contractor) for Construction company and work only for him self. His company paid him weekly wages and deducted 20% tax only from his salary before giving his salary, contractor did not deduct n.i.c class 4 or other contributions. When sending his TR for 2013/14, does HMRC has his income details in their system as contractor paid through their roll. He has paid large tax bill (around £5,000) but this does not taking into account his expenses, also no class 4 insurance has being paid. I will be completing S100 and S103 and unsure in which box should I enter amount that contractor has deducted his tax.
Should I send as normal by filling all boxes which are relevant to his business and HMRC will do the rest of job, or do I need any special arrangements for this return ?
I am very confused about this.
Any help appreciated.
