The way you have it, it looks like you've turned on the "round taxes during calculations" setting of the HikaShop configuration. That's actually also how PayPal calculate taxes. So if you turn on the "send order details" setting of the PayPal payment method, you have to have that option turned on so that HikaShop calculate the taxes like PayPal. If you turned off both options then PayPal will only see the total of the order which will be calculated like you want.

My customer swears up and down this was working before recently. I couldn't see any changes in the change log, though. Luckily he's not sending order details to PayPal so I just toggled the "round taxes..." feature off.

Note that it's highly possible that the calculations don't need any rounding based on how you configure your tax rates and the prices of your products. In that case, regardless of that option, it would produce the same results. For example if the untaxed price of the product is 100 and the tax rate is 20%, regardless of that option it will always give a taxed price of 120. It's when you need rounding for the calculations that you can see the difference. So it's totally possible that your merchant didn't see that before because he was using prices and tax rates that didn't need rounding up until now.
