I've just taken on a client with an overseas investment portfolio, with the overseas fund managers providing an income summary for the calendar year.
Using this information, the previous accountant reported income for the 2017 calendar year on the client's foreign pages for 2017-18, rather than income arising during the UK tax year.
Although it would make life considerably easier, I cannot find any justification for this approach and have never seen it done before. My expectation was to file actual income for the UK tax year with estimated foreign tax credit, and then file an amended return when the actual figures are available. However, if I do this, I would then need to file an amended return for 2017-18 as well, as income from 1/1/18 to 5/4/18 would be unreported otherwise.
Am I missing something? I would be most grateful to anyone who can point me in the right direction.
