Hi, this is something quite straightforward but my post-Covid infection brain is completely blank.
Tenant’s friend who lived with her died in August 2019 creating a ‘spare’ bedroom. Her son moved in from March 2020 to July 2021 but no-one informed HB. HB has now hit her with nearly 3 years bedroom tax overpayment for the spare room that was in fact occupied for 16 of those months. Can she just inform them of the son being there and ask HB to revise the overpayment decision or does the fact that it was over 2 years ago mean she is stuck with the overpayment for the whole period? Thanks.
Edit, sorry I am, aware of 12 month exemption rule
