ILR for a contractor

[kmln]

Hi,

I have been working as a contractor in the UK for last 3 years (to be exact, haven't done any paid work for the last one year, but was in a contract for 2 years prior). I am going to apply for ILR next week, based on Tier 1 General.

I wanted to know, to prove my earnings, do I submit my company's documents (company's accounts, bank statements etc.), or the income I received (e.g. payslips generated by my accountant)?

Best regards
