I have just come across this exact issue myself, i can process the order as a money order and no tax is on the order paperwork, yet it is showing in the cart.
The order total is however not including the 10% GST, although this is displayed correctly.
When trying to process the order via PayPal the order total is ZERO.
I have checked all the admin settings against another site that i have recently built and all are identical, so i cant see where the problem is.
I have replaced the ot_tax.php, ot_total.php and all the other ot_XXX.php files and the tax_rates.php, tax_classes.php files from a clean download of Zencart and this doesn't seem to have resolved the issue.
I am running Zencart 1.5.5e and Database Patch Level: 1.5.5, url is
http://djidronestore.com.au
I have attached some screen captures
image 1) Cart
image 5) Checkout / Payment screen Order total, is not including the GST although this is calculated correctly
image 6) The order total is missing and when processing the order via paypal it show up error 10525 which is expected after reading the forums
I have also deleted all the currency, tax and shipping settings in the hope that one of these was creating an issue.
really appreciate any help on getting this one fixed
Cheers
Murray
