Hi, I recently filed the self assessment declaration for a new partnership, that is run between my wife and me. The partnership started on 18 April 2018 and my wife joined the partnership in June 2018. The partnership's accounting period is 6 April to 5 April. The partnership uses the cash basis for accounting. I am in the process of completing my wife's 18/19 self assessment for her, I was just going to happily add her share of the profits so that she could pay her tax. But then I came across the boxes where it asks about the basis period and an adjustment if the basis period is not the same as the accounting period. I wasn't expecting to (and would prefer not to) make any adjustments. I'm a little (actually very) confused about this. We've divvied up the profits between us on a simple % basis for the period to 5 April 2019, do I need to make some adjustments because my wife joined the partnership in June 2018 and the partnership started in April 2018? If so, what do I need to do? Thanks in advance for any clarification on this.
