We had an order come through today for a sub total of $999.50 and sales tax is 8.25% and the Order Total came out at 1,075.77 instead of 1081.96

Our taxes are currently setup to use a Tax Table, and I have double checked the customers zip code which matches 8.25% and I have walked through the steps to duplicate the order total and on my end the order total comes out at 1,069.58   It's like the system is calculating taxes differently on different occasions.

Please see the attached screen shots.  One is my walk through with the wrong total, and the other is a screenshot of of the confirmation emails sent to our managers alongside a receipt that is put through our POS system and you can see the two are different and the physical receipt on the right of the screenshot is correct.

Any help appreciated.

DNN Version: 07.00.05 (130)
Smith Cart: 5.68.0

I was able to reproduce the issue, and my Total equaled a different amount then what it should be when 8.25% tax rate is applied.

Our shipping is set to free.  

There are no errors in the DNN log.  

Doing some troubleshooting it looks like Tax only gets thrown off once the Sub Total reaches a certain amount.  I do not know what that is, but I've done orders for a few hundred, to 500, etc. and it all calculates right.  The sub total at 999.50 is definitely not calculating tax properly though.

Any thoughts?
