Does Knock support GST?

Yes. Create a GST tax at your rate (for example 18%) and make it the default.

Is tax calculated before or after discounts?

Discounts reduce the line amount first, then tax is applied to the discounted amount.

Does Knock file GST returns?

No. Knock itemises tax on documents so your accountant has clean data.
