It depends on the implementation on the server side though.

I work for a website based in Europe and they pay me every month to my bank account (salary account). Every time I receive funds, I will get a call from the bank for confirmation and they ask for the source and reason. I will tell them the website name and software consultancy. They deduct some amount as charges, and credit the remaining to my account.

The question is: do I need to pay income taxes for this money I earned online?
