Found out yesterday that DH's boss (been with him 6 months) hasn't paid any tax or NI for him. Technically he's been getting paid cash in hand. I've been asking for wage slips so I can get tax credits sorted and get told its being dealt with
I've been claiming tax credits as his wages for the new job were the same as the old job so we just never changed the job details
Now, I don't know what to do. Are we in major trouble? Is it fraud to be claiming TC, even if I didn't know he wasn't paying tax?
Where do I go with this now?
