umbrella p11d dispensation and my self assessment

[tomysofi]

Hi.

I'm doing my self assessment and don't have a p11d. I rherefored asked it to my umbrella company but it turns out that they don't need to provide me with one.
So the question I now have is what am I supposed to do with my expances ?
Do I have to claim them on my self assessment ? If yes, were ? Or am I screwed ?

Thank you all !

Your umbrella company is your employer and therefore they should already have dealt with your expenses as part of their payroll process
