Do I need to complete an SA800 Partnership Return?
Partnership started trading from 1 Aug 2018 with year ended 31 July 2019. Husband had been trading as sole-trader with same year-end therefore his profits will be wholly assessed on his 2019/20 Tax Return. As for wife she'll be assessed on her share of the profits from 1 Aug 2018 - 5 Apr 2019 (8 months) firstly on her 2018/19 Tax Return and then again (creating overlaps) on her Tax Return 2019/20 (albeit for the full 12 months).
In order for me to declare her first 8 months Partnership profit share should I also be completing a Partnership Return for 2018/19? If so with just 8 months figures so as not to dupicate on 2019/20 SA800? And, any special boxes to ensure completed or ticked?
