So I have a registered business name as a sole proprietor and have made a small amount of money doing photography based work. 

However I also have other employment where I make more taxable income. 

I have expenses like camera gear, travel, print costs etc I'd like to claim as expenses. I'm just wondering if it would make a difference in my overall tax payment? With the photography stuff alone I am nowhere near close enough to be paying tax Soley on that income. Is it beneficial to still claim expenses to reduce my overall tax payment when both jobs are combined?
