Partnership- changing nominated partner

Hi, We want to change the nominated partner in our partnership so that they can sign off our tax return. Do we need to inform HMRC of this change and if so, how do we do this? (I spent half an hour on hold on the phone only to be cut off after 30 seconds by the advisor). Or is it fine for us to change this and just list them as the nominated partner on our next tax return form? Thanks Carmen

Hi,
Yes you need to notify this in writing  prior to the submission of the tax return- PM143000 - The nominated/representative partner
Thank you.
