Model Universal Credit reg 77 for owner-managers of a company

changelog.d/1948.added.md

@@ -0,0 +1,7 @@
+- Universal Credit now applies regulation 77 to a person who stands as sole owner or partner of a company carrying on a trade or property business.
+  - The company's income counts as their self-employed earnings on top of any pay from it. A loss counts as nil.
+  - The earnings count towards the benefit cap earnings exemption.
+  - The minimum income floor applies when the trade is their main employment.
+  - The company's capital replaces the value of their shares. Trade assets are disregarded while they work in the trade. In households with several benefit units, the shares leave the household's capital before it is shared out.
+  - The intermediaries (IR35) exclusion follows reg. 77(5) as in force: Chapters 8 and 9 of ITEPA Part 2 until 27 November 2018, and Chapters 8 to 10 from main-employment activities from 28 November 2018.
+  - New `owned_company_*` inputs describe the company. Every input defaults to no such company, so existing datasets are unchanged.

+  Annual simulations use the rule in force at the start of each tax year, so
