I haven't had much experience with tax returns in terms of full time work so I'd like some advice for the term/saying "claiming tax back".
I'm working in an architectural firm at the moment and was wondering if I could claim tax back on things such as architecture talks, architecture books, Sketchbooks, Cameras, etc. These items are not REQUIRED for work, but for me they help with professional development. Can I claim tax back on these items and how so? Any formal proof apart from receipts?
