Product taxes calculated wrong in back office

[GroovyG]

Hi Guys,

 

Just installed the localization pack from Mexico. While adding prices to my products I noticed the taxes are not calculated correctly. 

 

Taxes in Mexico correspond to the 16% of the total price. Here is the correct breakdown of a product costing $1,000:

 

Pretax price: 840

taxes (16%): 160

Total: 1,000

 

 (1,000 x .16 = $160). However the calculations done automatically in the back office do not match. 

 

Can someone help?? attached in an example.

 

 

Thanks 

Emmanuel
