As per my knowledge I can that in almost all countries of world, the CAs and Taxation Authority will ask you only one thing that from where you get the amount for expanses as you do not have any sales ? You just have to clarify that in a very proper way and for that you take the help of your accountant or revenue lawyer. They can guide you well as per your countries laws.

And still if you want any help then I am there to help you.
