Help is at Hand

IR35 impacts how you work and how much tax you have to pay – so it’s important you understand how the rules apply to you.

As a limited company contractor, whenever you get a new contract or the terms of your contract change, your end hirer (unless they’re small) must assess your assignment status and issue a status determination statement to let you know if you’re ‘inside’ or ‘outside’ IR35.

Even for the most experienced limited company contractor, this can be difficult to understand and monitor – especially if you’re working on multiple contracts. Our IR35 experts are here to help with advice, our assessment tool and working options for inside & outside IR35 roles.
