My wife & I retired in May 2021, closing down our small business (not a limited company). I'm currently filling in our SA 800 Partnership Tax return and am wondering whether I might be able to extend our final accounting period to 15+ months (in order to bring it up to point of closure), or whether I have to stick to the normal 12 month period for 2020-2021 and fill in another (final) form for 2021 -2022 with an accounting period of just 3 months. I'd really like to get it over and done with if possible, since I understand that accounting periods are going to have to be aligned with HMRC's financial year from 2022 and businesses will then have to present their accounting information from April to April. This will create further complications.
I've tried asking HMRC but, as you will probably already be aware, getting a response from them is proving nigh on impossible.
Thankyou for your help.
