Sales Tax - won't calculate correctly

jsarc — Sun, 21 Sep 2025 12:50:08 GMT

Hi, I'm in Quebec, and the Sales tax are GST 5% and QST 9.975%.
Those are entered correctly in my taxes settings in square.

A transaction of 100$ + tx should be

GST 5$

QST 9,98

for a total price of 114.98$.

However, Square gives me

GST 5.50$

QST 9,98$

It seems like the GST is calculated over the QST, thus the 0.50$ difference.
is there any way to fix that?

Many thanks

Ok, I've created another GST at 5%, then disabled the other one and that fixed the problem.

Weird.

So it's a bug.
