**celinalinley**Your system is inaccurately calculating basic math for tax. In my screenshot the subtotsl is $65. and my tax rate is 8%. 8% of 65 is 5.20 not $6.00. The calculation behind your code is wrong its not giving the right answer. See screenshot attached.THIS IS A HUGE PROBLEM.

**Jim_R**I'm afraid you accidentally sent us an incorrect screenshot so I checked the actual form https://www.jotform.com/70520866195157 and did exactly as how you described it.

Here's how it looked like from my perspective:

Can you please check it again? The computation should work properly. If you're still seeing it differently, send us a screenshot by following the guide I'm linking below. Don't reply via email, open your thread by clicking this link, then post your reply and screenshot from there.

**Related thread: How-to-add-screenshots-images-to-questions-in-support-forum** **exoteric**I am also experiencing the same issue with incorrect tax calculation from the payment widget after a discount/coupon code is applied. Instead of calculating tax at the discounted price the tax calculation is being calculated at full price i.e. ( Let's say I have a $25.00 off discount code/coupon and am applying a discount to an item priced at $100. The tax rate is 9%. it's calculating the tax at full price which in this case is $100.00 and not $75.00)- JotForm Support
