I am sorry if it is inferred in some arcane way that accountants understand, but I am not an accountant and I can find no specific statements about time limits, maximum number of years it is possible to carry trading losses from etc. As you were so quick and kind to reply initially, I took your silence follow-up reply to mean that I must be thick (not that I am suggesting you would say such a thing!) and that such references must be there, so I looked again, and I must be doubly thick because I still could not find anything, and lay it out before you below, so that I may be shamed (which if it is there, I deserve to be).
I followed your link to the document I had already consulted, and read this:
Carry forward a trading loss
Certain losses that your company has not used in any other way can be offset against profits in future accounting periods.
NO MENTION THERE, SO I CLICKED ON THIS LINK: "Find more information about carrying forward a trading loss" AND READ THIS:
Carry forward Corporation Tax losses
Find out about the type of losses your company can offset against profits in future accounting periods.
AND READ THIS:
Carry forward a trading loss
Your company can carry trading losses forward to deduct from profits of future accounting periods as long as the trade continues.
If your company is using a carried forward trading loss in an accounting period that ends before 1 April 2017, you can only use the relief against profits of the same trade.
Where your company is using a carried forward trading loss in an accounting period that starts on or after 1 April 2017, the situation depends on when your company made the loss in question. If your company made the loss:
before 1 April 2017, it can only be used against profits of the same trade
on or after 1 April 2017, it can normally be used against your company’s total profits
There are special rules for accounting periods that start before and end on or after 1 April 2017.
If your company is part of a group and has carried forward trading losses made on or after 1 April 2017, other companies in the group may be able to use those losses. This is called group relief for carried forward losses.
AS OUR TRADE REMAINS THE SAME, NOTHING IN THE "start before and end on or after 1 April 2017" LINK WAS RELEVANT, SO I CLICKED ON THE "Find more information about trading losses" LINK, BUT THAT TOOK ME BACK TO THE BEGINNING.
Where and how have I gone wrong?
Where does it say the maximum number trading loss years that can be carried forward?
