Describe the bug

Something got broken in the latest update regarding taxes…

Specifically, I’m unable to include a tax on my Purchase Orders…

Steps To Reproduce

Similar to the demo example above, I cannot add a tax to my Purchase Orders anymore. Create a default tax rate in Settings > Tax then create a new Purchase Order, and attempt to set that tax rate to your PO subtotals. The issue will surface in this process.

From my own instance:
InvoiceNinja Tax Issue in Production

Expected Behavior

As was the case prior to updating InvoiceNinja to the latest version, you should be able to just seamlessly set a calculated default tax rate on any document (Invoice, Quote, PO, etc.) without any issues occurring.

Hi,

I suggest asking in a discussion on GitHub.
