HMRC are issuing One to Many (or ‘nudge’) letters from the end of August 2023 to those taxpayers who made a gift holdover claim in their 2021/22 tax returns, but either did not submit the necessary claim form, or the submitted form was unsigned by the donor and recipient. Recipients of these letters have 30 days to either amend their tax returns or submit/resubmit a completed form; failure to do so may result in HMRC’s amending the tax return or opening an enquiry.
