UK RE Taxes

There is no depreciation in the UK, only Europe. 

For everything else, sit down with your tax guy and ask him. There's no shame in asking questions if they're not stupid (and most aren't) especially around complex topics like tax. 

You'll want to consider asset vs spv disposal, CIR & grouping structure, loss restrictions, cit, cgt, capital allowances etc etc. 

To put this another way, and expanding on the above, but this really applies to most things

You're an A1, with limited experience and with all due respect, knowledge. Your purpose is to translate concept into analysis for those that you support. 

You will be expected to have a base knowledge (excel, property concepts, structure concepts at least modelling) but when it comes to the minutiae (legal, technical, structure etc and in this case tax) no one is expecting you to be a subject matter expert at A1. Those expecting you to be a subject matter expert are either insane or have hired incorrectly (and that is no disrespect to you - if they wanted someone to model tax from day 1, they should have hired A2+)

You should be a sponge of  information and learning along the way by the time that you're ready for a promotion, you're ready to ask your advisers (external and internal) key questions as to whether they have considered x, y and z, or if a, b or c could propose future problems. 

You can't get there if you aren't asking the right questions in your learning phase. So yea, don't be afraid to ask questions. 

By all means use the forum and ask questions, or use the Internet and research the question before hand. But your question just seemed far too high level given the topic so just wanted to give my 2 cents. 

Don't however ask what is NOI.
