Shipping cost not included in sales tax for USPS and UPS extensions

[Alex1]

I am using AbanteCart version 1.3.4 and the shipping cost is not being included in the sales tax amount. I am using the shipping extensions included with version 1.3.4.

The store's tax class is "Taxable Goods" and for both the USPS and UPS shipping extensions I have the tax class set to "Taxable Goods".

I cleared the cache however that did not help. I attached an image with screenshots of the settings and the checkout page.

Maybe there is another setting that I need to select to get this to work. Does anyone have any ideas on how I can get the shipping cost to be included in the sales tax?

I figured out why the shipping cost was not adding to the sales tax and now have that issue resolved.

On the Order Totals extension, the Taxes row Calculation Order column was set to 3 which was the same that the Shipping row was set to. I changed it to 5 and now the shipping cost is adding to the sales tax.

I attached an image with screenshots of the Order Totals extension and checkout page showing it now working.

Hello.
Did you select the Tax Class in the shipping extension settings?

Hello,
Yes, in the shipping extension settings, I had selected the Tax Class.
The issue was caused by the taxes calculation order being set to the same number as the shipping calculation order in the order totals extension. This resulted in the shipping cost not being included in the taxes.
When I changed the taxes calculation order to a higher number than the shipping calculation order, it then started working and the sub-total plus shipping were both included in the taxes.
It is working perfectly now.
