Hi KlentB, 

I know that some expenses aren't allowable. However, why, for example, are half of my Zoom subscription payments under 'allowable' and half of them under 'not allowable'? 

It is an allowable expense, it's from the same provider, under the same category. What part of the system chooses that half of the subscriptions aren't allowable? 

I've put the expense under 'Other business expenses' as there doesn't seem to be another category which is more suitable. 

Could you advise if this is correct?

This is a massive flaw in the software.  The automation isn't always going to get it right, so there should be a way of manually changing it so the Taxes data is actually reliable. 

Thanks in advance.
