I have a case in which user needs to add the tax in amount not in %. For this as per Odoo default system not allow to add the tax in the amount but as a workaround solution I am currently managing this by the service product.

I created the service product and in the accounting I set the tax accounts. Now user select this product on the invoice and add the amount against that product. Journal entry and all things work properly but only one problem that whatever the tax amount user added that not reflect in the tax report that coming in the default system.

Is there any solution how can we reflect this amount in the tax report.

Odoo version 16
