I'm quite sure they will align. Some interesting other implications too. Eg UK sub with EU parent company can get audit exemption in certain circumstances. Not for periods starting 1/1/21.
I understand that UK exit from Brexit could have some exemptions removed like requirement to prepare consolidation of accounts for UK companies having EU parent companies. Where can i get more information about this applicability and from when will this change affect UK companies.
Yes in some circumstances you can file the TopCo accounts of a EU parent company.
From periods comm 1/1/21 you can't do that so must prepare and file consol accs at UK level.
Similar situation re exemption from audit via EU parental guarantee.
(Sorry, not an IFRS issue).
