    Payment Tool: Rounded off value in the "Location based tax" option shows an incorrect payment total

    Asked by bdoodle on March 01, 2016 at 01:08 AM

    When my customer enters WI as the state in the address, tax is calculated on the subtotal of my purchase order. Sometimes when the purchase order has an odd tax amount, it isn't rounded the same way in the tax and total fields. The total value is a penny off.  See below. How to I prevent this?


    A form where this is happening for me is:



    In the above example:  Although it shows up as  $39.92 on the screen, when I include the purchase order total in email, it appears as $39.93.  The value in the hidden finalOrder field which I've populated from the purchase order total is $39.92, and this value is passed to another form via a Thank You page link and appears in email as well.  It must agree with the purchase order totals on screen and in email, and the subtotal, tax, & shipping should add up to the purchase order total on the screen.

    Thanks for your help.

    I was able to replicate the problem, it seems like the total price is not adding up the rounded off value of the custom tax.


    I have forwarded this to our developers to have it checked and fixed. Apologies for the inconvenience. We will update you as soon as this has been resolved.
