An early stage startup started mid 2018. Can I claim expense under personal income tax filing for 2018?

Started working on a technology product mid last year. No revenue yet. I haven't set up a business structure (Inc., LLC or anything like that). I could be considered a sole proprieter for now. 

I have expenses from last year - mainly to develop the software product with an overseas development company. Can I file overseas software development expense under personal income tax?

No, start-up cost (even when paid in a prior year) will be claimed when you begin operations.
