RE: Sales tax is not calculating in product receipt
                     
                    
                      
                        Hi John Perry,
Are you getting any error notification while posting product receipt? Is it possible to share the screen shot of that?
Which type of item you are using - stocked / non-stocked? Are you using procurement category in PO?
Meantime; you can check in below areas whether you have made the setup or not.
--- Go to Inventory and warehouse management parameters > Inventory accounting > Post physical sales tax. Is that set as 'Yes' ?

--- Go to Inventory management > Posting > Transaction combinations. Check if you have set the Activate sales tax group 'Active' or not.

Check from your end all these areas if properly set and update in this forum.
Best regards,
