How to Report Zero-Rated GST Exports?

Hey everyone, I’m in a bit of a bind, and I can’t call the CRA for answers because they are on strike, so am hoping someone here can help.

My situation is as follows: I am filing taxes for the first time for the new online marketing business I started last year. In case it’s important to note, the business and tax return are officially in my name and tied to my SIN rather than a business name and number. The two clients I have are both based in Europe and pay me in euros. As the services I provide should all be zero-rated, I have not charged any of them GST nor have I registered for a GST number.

As a result, my accountant, who uses ProFile, doesn’t know how to report that my income is zero-rated, and ProFile automatically flags the field where the GST should be. I don’t want to file my taxes in their current state lest the CRA sees it as a red flag that I earned a substantial income yet did not charge any GST.

After doing some research into this, I learned (and communicated to my accountant) that I need to fill out a GST return form. However, can I do this without having a GST number? Do I need to register for a GST number even though all of my income is zero-rated?

How can I make things clear (using ProFile or any other methods) to the government? What options do I have here?

Any advice on this will be greatly appreciated, as I’ve spent hours the past few days trying to figure this out.

Thanks in advance!
