Tax line not getting created on accounting imported AR Invoice

Summary:

We are currently facing a issue. We have Configured a tax classification code and created a tax setup based on that. When we are creating manual AR invoices using the same tax classification code correct tax lines are getting generated on accounting. When we are importing the transaction through auto invoice import with same data, it is creating the invoice successfully but on accounting the tax lines are not generating.

On clicking the "incomplete" Option on the invoice and then completing it and then accounting the invoice, the tax lines get generated.

Can you please help us to find out why the transaction is not creating tax lines while accounting an imported transaction?
