I moved into an apartment 6 weeks ago in which i pay $200 a week incl bills. The landlord who also lives in the apartment bought it around 8 weeks ago with the home owners grant I am unemployed and have been getting rent assistance from centrelink. i gave her the form to sign which she said she wouldn't as she doesn't want the property to be an investment property (now i know why she wanted cash in hand for the rent) and is worried that if she signs it, it will be on centrelink's records which will get cross referenced with ato or the mob who have a record of who owns houses and she will get done to renting when she shouldn't be or even if she can rent, she isn't declaring it. so i have given my 2 weeks notice and informed her that i may have to pay centrelink back for what i claimed which i thought i was entitled to. she just came to me and said she would sign the form as a kind gesture and hopes that it won't get picked up in the system that she has rented and not declared. what i want to know is how well linked is centrelink with the ato on these matters? she shouldn't even be on centrelinks records as she has never clamed off them so she wouldn't even have CRN. surely me saying she's my landlord would just go on as a note on my file and that's it? would the ATO be able to trace that she has rented a room out? note by the time she lodges a return next year my address will be different as I am moving in 2 weeks. so in total she has rented the room out for 7.5 weeks. surely the ato would have bigger fish to fry?
