<prompt> Human: My brother in law is working for an employment agency in Canada. The company is paying him in cash for the work hes doing at a warehouse. When he asked about a T4, they raised their hands, shaking them saying We dont speak about that. Dont ask for one.Is he at any risk? He plans to remain honest and claim it. I cant recall, but is there an option to claim cash payments that you get from an established company? Ive always had a T4 so I havent had experience with that.Any input on this is appreciated,Thanks!  <response>: If the company doesnt make him an employee, then hell have to claim business income as an independent contractor. He can report his earnings and also claim eligible expenses and deductions there. If hes under 30k then he doesnt have to collect or claim GST. Honestly though, theres very little risk to him, and if hes a teenager with a low paying job he should just accept the cash and keep quiet. Its good to be aware that the company is not fully on the level though, he wont pay into or be entitled to EI or CPP, wont be covered by workplace insurance if thats appropriate, and will have minimal recourse to labour code violations
