I'm applying spilt year treatment for Year 23/24, some key dates as below: 18 Jul 2023 Arrived UK 18 Jul - 29 Aug Staying in AirBnB / Hotel 30 Aug 2023 Started a home rental 20 Aug 2023 Received an income for working during May 2023 [ITEM A] 1 Sep 2023 Received an income for working during Jun 2023 [ITEM B] I supposed the start day of being the UK tax resident is on 30 Aug 2023 according to CASE 4, is that right? My question is, are ITEM A and ITEM B are taxable income?
