Hi all my partner of 3 years has finally moved in with me. Hes earning £22,000 a year and I am earning around £6,600 a year part time. I have a 10 year old from a previous relationship as well. My question is once I let my Credit people know that he is living with me and earning, how much do you think we would be getting from the Working tax credit if anything? I used the online calculator it was pretty high and would push out combined earnings to £29,600 a year or something.
