unclaimed expenses on rental property

Hi. I am non resident and return to the uk once a year to check rental properties. I have never claimed expenses associated with these trips previously but now understand these are allowable expenses. I will claim the costs for my 2023/2024 trip on my next return but can you advise me on the process to claim any previous years trips and how many previous years I can claim for. I have tried ringing many many times but the helplines are either not in use or I get cut off. Thank you

Hi ,

Thanks for your question. In terms of previous years, you may claim on expenses up to four years prior to the current tax year, as far back as 2020/2021. I have attached relevant guidance outlining the overpayment relief procedure which should offer further detail for your query: SACM12150 - Overpayment relief: Form of claims  . Thank you .
