Sales Tax and Order Total

[grantli2002]

I just happen to find out my sales tax doesn't work correctly. I followed the installation guide from the manual. There was a default state FL in the default installation. I added NJ and add the rate 7%.

 

The weird thing is: The tax rate was not calculated right and it was not added up to total order amount.

Sub-Total: $42.79

Flat Rate (Best Way): $5.00

New Jersey Sales Tax: $2.80

Total: $47.79

 

The product before tax was $42.79. Shipping was $5.00 The total amount didn't add the sales tax at all. Furthermore, the tax should be: $3.00 ($47.79x0.07=3.00).

 

I tried using Florida address, I got the same result. Tax was calculated wrong and was not added up to the total amount.

 

I thought maybe somehow US address will be charged a tax rate? I didn't see it. I tried another state, WA, it was not charged sales tax.

 

Any help is appreciated.
