Tax not calculating for some reason

Hi everyone, I’m having an issue with Woocommerce not calculating tax at all. No matter what I do, I seem to get a tax value of 0. All I want to do is tax products sold in the state of Michigan at a rate of 6%. Anywhere outside of the state the rate is 0%. For whatever reason, I can’t get this up and running.

As you can see, tax is being calculated at $0.00. I have the same value when clicking “Checkout” and looking there.

Here you can see that the item is set to taxable with the tax class “Standard.”

These are my tax options for the site. I’m basing tax on the customers shipping address and using the “Standard” tax class again.

Here you can see the settings for “Standard” tax class. I only have the one class so I know that I’m not mixing this up with another class or something. I have it set to US, MI, *, *, 6%, Priority 1. I see that shipping is checked in the photo. I don’t actually want to tax shipping, but the problem persists even after unchecking shipping.

This last one is s shot of the code used to calculate the tax in the theme. I double checked that this code is valid and even copy/pasted the stock code in instead of this. No such luck.

Any help on getting this tax issue solved would be greatly appreciated.
