How do I submit a quarterly update to HMRC as a joint property owner?

How do I submit a quarterly update to HMRC as a joint property owner? Send your own update with your share of the rent by each deadline, starting 7 August 2027 for 2027 joiners. For a jointly let property you can leave expenses out until after the tax year ends. No. Each of you sends your own updates, covering your own share. GOV.UK says you do not need to link your digital records to the other landlord's. Yes, for jointly let property only. Your updates can carry your share of the income alone. You must add the expenses after the tax year ends, before you submit your tax return. Only if you choose to send income and expenses. The income-only option covers just the income categories, so your share of finance costs is added with the other expenses after the year end.
